PROBLEM TO BE SOLVED: To prevent the speed component caused by mutual inductance between coils from being intermingled in a speed signal and being fed-back when a drive coil and a speed detection coil are arranged in close proximity. SOLUTION: A current detection circuit 6 is provided in a current-carrying circuit for a drive coil 1, and the detected signal is differentiated in a signal generation circuit 7. A signal for cancelling a signal component caused by mutual inductance between a drive coil 1 and a speed detection coil 2 is generated, and the above-mentioned cancellation signal is synthesized with a signal output by a speed detection circuit 4 in a signal synthesis circuit 8 to generate a feedback signal to an electricity conducting control circuit 3. In this way, the feedback signal includes only normal speed signal component detected by a speed detection coil 2, and it becomes possible to control a position of a movable part 5 in a wide band at high speed and with high precision.

PURPOSE: To provide a small speed detecting device suitable for speed detection and having the flat output characteristic of the induced voltage at a low cost. CONSTITUTION: This speed detecting device 1 is constituted of a columnar magnet 3 fixed to a lens barrel at one end section and extended in the direction of an arrow D which is the optical axis direction, a nearly cylindrical bobbin 5 having a hole 5a for inserting the magnet 3, and a coil 4 wound with a lead wire on the peripheral face 5d between outer flanges 5b, 5c protruded at both end sections in the axial direction of the bobbin 5. The peripheral face 5d of the bobbin 5 wound with the coil 4 is formed into a taper shape made finer in diameter toward the base end section of the magnet 3, the actual magnetic gap between the magnet 3 and the coil 4 is changed in the moving direction, and the output characteristic of the induced voltage is made flat.

PURPOSE: To detect the moving speed of any conductive moving object in a non-contact state without applying a mark by detecting the current induced in the moving object by an exciting coil by a magnetic detection coil. CONSTITUTION: When a current (ib) flows to an exiting coil 12b, the magnetic field ϕ piercing a moving object 10 is increased and a current I is induced in the moving object 10 by the increase of the magnetic field ϕ. When the moving object 10 moves to the left, an electric power producing current Iv is induced in the moving object 10. Therefore, a current (I-Iv) flows in the vicinity of a magnetic detection coil 12a and a current (I+Iv) flows in the vicinity of a magnetic detection coil 12c. The currents (ia), (ic) corresponding to the magnetic field change by the currents (I-Iv), (I+Iv) are induced in the coils 12a, 12c. When both coils 12a, 12c are reversed in output polarity to be connected in series, a current i=(ia-ic) flows across output terminals A, B. Since the current Iv corresponds to the speed of the moving object 10, the moving speed of the moving object 10 can be detected on the basis of the output current (i).

PURPOSE:To estimate the speed of a vehicle body adequately even if an error occurs in the detection of an actual acceleration and a driver does not ease an accelerator in slipping. CONSTITUTION:An acceleration VBF corresponding to a wheel speed and an actual acceleration GX are compared, and whether a wheel starts slipping or not is judged with a slip-starting judging means 216f. When the wheel starts slipping, the values with regard to the actual acceleration GX are integrated with time based on a body speed VB0 corresponding to the wheel speed obtained at this time and the actual acceleration. The obtained speed value is added to the body speed VB0 corresponding to the wheel speed, and the body speed is computed. The body speed is made to be the estimated body speed VB with a body-speed estimating means 216g corresponding to the actual acceleration. After the specified time has elapsed from the start of the slipping of the wheel, the adoption of the estimated body speed with the body-speed estimating means 216g corresponding to the actual acceleration is stopped in this constitution.

PURPOSE:To estimate the speed of a vehicle body adequately.

When the wheel starts slipping, the values corresponding to the actual acceleration GX are integrated with time based on a body speed VB0 corresponding to the wheel speed obtained at this time and the actual acceleration GX. The obtained speed value is added to the body speed VB0 corresponding to the wheel speed and the body speed is computed. This body speed is made to be the estimated body speed VB with a body-speed estimating means 216g corresponding to the actual acceleration. When the slip of the wheel is the slip caused by the acceleration of the vehicle, the lower limit is clipped so that the value GX of the actual acceleration used in the body-speed estimating means 216g corresponding to the actual acceleration becomes 0 or the positive specified value or higher.

PURPOSE:To enable detection of a relative speed between positions on and below a coil spring without any differentiation processing using a compression force working on a car body from the spring. CONSTITUTION:In a shock absorber 6, a piston not illustrated is inserted into a cylinder 4 axially free to slide. The piston is connected to one end of a piston rod 7 while the other end of the piston rod 7 is mounted on the body 1 through an upper support 2. The cylinder 4 is provided with a spring receiver 10 and a coil spring 3 is arranged between a sensor section 3 and the spring receiver 10 being compressed beforehand. As the coil spring 3 is arranged being compressed, a compression force works on the sensor section 5 even at the initial state. A piezoelectric body is provided inside the sensor section 5 and a rate of change in compression force, namely, relative speed is taken out as voltage by the piezoelectric body and a resistance.
155	DETECTING DEVICE OF SPEED	JP23894488	1988-09-26	JPH0287071A	1990-03-27	KAMIIDE TAKUO
PURPOSE:To enable highly-precise measurement of a speed of an object making a linear movement by a simple construction, by using a magnet rod and a plurality of coils and rectifiers. CONSTITUTION:A magnet rod 1 extending in a prescribed direction is divided in a plurality of permanent magnets 1a, which are so arranged that each magnet 1a is different in polarity from an adjacent one. Coils 3 and 4 are disposed in proximity to the rod 1 so that the axes thereof intersect the direction of the extension of the rod 1 perpendicularly, and they are connected to bridge rectifiers 5 and 6 respectively. When the rod 1 and the coils 3 and 4 move relatively in the direction of an arrow in the figure, according to this constitution, alternating-current electromotive forces are generated in the coils 3 and 4. These alternating-current signals are rectified in the rectifiers 5 and 6 respectively, and direct-current voltage signals obtained therefrom are inputted as a synthesized direct-current voltage signal Vi to an amplifier 7, amplified thereby and outputted Vo. Since the signal Vi differs according to the speed of linear movement of the rod, it increases with an increase in the speed of the linear movement, and the signal Vo increases also therewith. Accordingly, the speed of the linear movement of the rod 1 can be determined by measuring the amplitude of the signal Vo.

PURPOSE:To reduce a space occupied by a sensor, by a method wherein a detecting means, outputting a speed signal in accordance with the passing speed of respective slits of a slit plate only during a period when the slit plate, provided on a carrier, is detected, is provided in the title detector. CONSTITUTION:When light beame, generated by a light emission diode D1, are intercepted by the upper area UA of a slit plate 16, the potential of the collector of a phototransistor Tr1 becomes a H-level and a carrier detecting signal is outputted from a terminal T1. When the light beams, generated by the light emission diode D2, are intercepted intermittently by the lower area LA of the slit plate 16, in which slits 16a are formed, the potential of the collector of the phototransistor Tr2 becomes H-level intermittently and a speed signal, having a pulse frequency corresponding to the moving speed of the slit plate 16, is outputted from the terminal T2.

PURPOSE:To improve an S/N by providing plural detection coils which generate signals corresponding to the moving speed of a moving body through electromagnetic inducing operation and canceling them by mutual induced electromotive force generated by a driving coil. CONSTITUTION:The moving body 50 is constituted of a movable part 34 with a tracking coil 28, a frame 36, the speed detection coils 46 and 48, etc., and supported by two guide shafts 53. When a current flows through the coil 28, the moving body is moved as shown by an arrow 26 by magnetic flux from a magnet 52. At this time, detection coils 46 and 48 generate electromotive forces corresponding to the moving speed through electromagnetic inducing operation based upon the magnetic flux from the magnet 56. Further, an electromotive force is generated as a noise through the mutual inducing operation of the coil 28. Those noises are at nearly equal potentials and in the same phase, so the coils 46 and 48 are connected differentially to cancel the noise with each other.
