PURPOSE: To make improvements in accuracy by forming a damper into the telescopic structure of a cover and a cylinder, composing a transducer of a conductive coil and a magnet, and having it carried on a cover member of a damper, in this captioned system detecting the relative velocity between two vehicle constituent elements connected by a fluid-type damper. CONSTITUTION: A spring 16 and a fluid-type damper are set up in space between two vehicle constituent elements 12 and 14, thereby constituting a suspension system 36. Then this fluid-type damper 18 is formed into a telescopic movement mode with a cover 36, whose one end is supported on the constituent elements 12, and a cylinder 28 supported on the constituent elements 14. A velocity transducer 26 is comprised of a conductive coil and a magnet and carried on the cover 36. In this constitution, the flux field of the magnet is changed by each relative displacement of these constituent elements 12 and 14, inducing a voltage in the coil. This voltage is transmitted to a control means 20 from a connector 24, and it is offered to control while it is monitored by a monitor 25. With this constitution, monitoring accuracy is improvable.

PURPOSE: To improve traveling stability and riding comfort of a road surface traveling vehicle by furnishing a stationary cover made of a non-magnetic material with a sensor coil, providing a permanent magnet on the guiding closed side on a free end of a damper cylinder and providing an evaluation circuit. CONSTITUTION: A vibration damper is connected to a wheel mass by a connecting member 4, and a piston rod 2 is connected to a car body mass through a fixed member. The rod 2 passes through a guiding closed member 36, a permanent magnet 10 is fixed on the member 36, a cover 35 made of a non-magnetic material is fixed on the rod 2 through a connecting means 19 and a sensor coil 8 is buried in it outside of a damper cylinder 1. When the cylinder 1 is pushed up by a non-planar property of a road surface, the magnet 10 moves upward in the coil 8, and voltage in proportion to speed is induced in the coil 8. This induced voltage is transmitted to a filter 20 through a connecting line 12, supplied to a microprocessor 28, and this evaluation circuit eliminates work of the vibration damper and prevents transmission to the car body mass.

193	Measurement of particle speed for inkjet printer	JP21899682	1982-12-14	JPS59108961A	1984-06-23	KOUNO ICHIROU
PURPOSE:To measure the speed of ink particles at a high accuracy by gaging a magnetic field generated with a magnetic field detector section depending on the moving speed of charged particles. CONSTITUTION:When charged particles move in the sequence of Q1 Q2 Q3, the intensity ¦C¦ at the point C indicates the maximum at the point Q2 from the formula. Here, the intensity of the magnetic field at the point C ¦C¦=Qv/4pir<2> naturally changes in the maximum value with variation in the speed (v). In this theory, ink particles 10 injected from a head 1 of an inkjet printer are charged with a fixed load Q large enough by a charging device 2 and a magnetic detector section 3, for example, comprising a Hall element close to the moving path to measure the intensity ¦C¦ of the magnetic field of ink particles varying at an angle theta once converted into an electric value. In other words, the speed (v) can be determined by measuring the time and distance until ink particles reaches the peak in the intensity ¦C¦ of the magnetic field, namely, the point right above the magnetic field detector section 3 from a certain point.

195	SPEED DETECTOR	JP8596779	1979-07-09	JPS5611360A	1981-02-04	TAKASE HIROBUMI
PURPOSE:To make it possible to detect the speed of reciprocating movement of a long stroke directly with a high precision, by holding always the density of the leakage magnetic flux at a fixed value in the region where the leakage magnetic flux exists. CONSTITUTION:A leakage magnetic flux is generated between magnetic poles 3a and 3b as shown by the dotted-line arrow in the figure. Here, when displacement corresponding to the speed of a detected object is given to coil 2, Hall element 5 fitted to coil 2 converts the leakage magnetic flux to a voltage according to the moving position. This voltage is compared with the voltage of reference power source 6 by voltage comparator 7, and the deviation voltage is fed back to electromagnets 4a and 4b to increase or reduce exciting currents of electromagnets 4a and 4b, and control is performed until the deviation voltage becomes zero. As the result, even if coil 2 is moved, intensity of the leakage magnetic flux near coil 2 is always held at a set fixed value. Thus, the speed of reciprocating movement of a long stroke can be detected directly with a high precision.
