摘要： This invention relates to a device for removing short fibers from a mass ofibers. A pair of perforated cylindrical bodies are opposed to each other with a predetermined spacing defined therebetween, and static electricity is applied across the perforated cylindrical bodies. A suction-wise removing device is installed in at least one of the perforated cylindrical bodies. The initial end of a transfer conveyor is located on the surface of one perforated cylindrical body adjacent the opposed region. Short fibers contained in the mass of fibers fed to the opposed region by a feeding device are drawn into the suction-wise removing devices through the through holes in the cylindrical bodies by the action of electrostatic force and suction air currents. The mass of fibers having the short fibers removed therefrom are oriented by electrostatic force and transferred by the conveyor while being maintained in this oriented state.

摘要： A vibration and acoustic wave detecting device employing a piezoelectric element has a construction such that a piezoelectric element comprises a first surface electrode disposed on a first surface of the piezoelectric element and having a first output terminal of the detecting device, a second surface electrode opposite to the first surface thereof, a side electrode disposed to surround a side surface of the detecting device and having portions respectively extending over the first and second surfaces, the three electrodes being disposed separately from each other, and a resistor disposed on the piezoelectric element to extend across the first surface electrode and the side electrode and to be connected therewith electrically, and the piezoelectric element further comprises a conductive member which is attached to the piezoelectric element to be in contact with the second surface electrode and the side electrode and hence to provide electrical connection between both electrodes. The conductive member supports the piezoelectric element and also provides its second output terminal. Thus, the piezoelectric element and the resistor are electrically connected in parallel between the first and second output terminals of the detecting device. This construction makes it possible to simply and easily manufacture a detecting device incorporating a resistor for increasing the available frequency bandwidth without causing any problem in the manufacturing process.

摘要： A knock detecting apparatus for an internal combustion engine includes a vibrating sheet branched into a plurality of vibrating reeds by forming a recess from one end of the vibrating sheet. The vibrating reeds have different lengths, shapes or thicknesses, and the other end of the vibrating sheet is fixed to a supporting member which is secured to the engine thereby to allow the vibrating reeds to vibrate with different resonance characteristics in response to the vibration of the engine caused by the knocking. The vibration of the vibrating sheet is detected, for example, as a change in reluctance by forming a magnetic path through the vibrating sheet and air gaps respectively located between the free ends of the vibrating reeds and a core.

摘要： A spark plug includes a body of dielectric substance mounted on one of central and earth electrodes and having polarization effects. A gap for capacitive discharge is defined between the body of dielectric substance and the other of the electrodes, and a gap for inductive discharge is defined between the electrodes, which gap for inductive discharge is larger in dimension than the gap for capacitive discharge. With the arrangement, capacitive discharge to be produced in the early stage of discharge is caused at low discharge breakdown voltage due to polarization effects of the body of dielectric substance, and inductive discharge taking the main part of discharge for ignition is produced by utilizing the capacitive discharge of low voltage as trigger, thereby lowering discharge breakdown voltage to improve ignition performance of the spark plug.

摘要： A knock detecting apparatus for an internal combustion engine includes a vibrating reed of magnetic material. One end of the vibrating reed is fastened to a supporting member interposing therebetween a magnet and one end of a core. The free end of the vibrating reed confronts with the other end of the core with an air gap therebetween to form a magnetic path including the magnet, vibrating reed, air gap and core. As the vibrating reed vibrates in response to vibration of the engine on which the supporting member is securely mounted, the distance of the air gap changes causing a change in magnetic flux passing through the magnetic path. The change of magnetic flux is detected by a coil wound on the core. The resonance characteristic of the vibrating reed is arranged to fall in the frequency range of the knocking.

摘要： Method and apparatus is provided for calculating an optimum ignition timing for an internal combustion engine on the basis of values set in dependence on operating conditions of the engine. With a view to prevent ignition times in two successive cycles from differing remarkably from each other, the ignition time or angle for the current cycle is controlled with reference to the ignition time or angle in the just preceding cycle. As one example of the control, in the case where the ignition time electronically anticipated for the current cycle appears to have deviated from the preceding ignition time by more than a predetermined value, the anticipated ignition time is modified to result in the optimum ignition time by adding to or subtracting from the anticipated ignition time a predetermined value. Alternatively, the optimum ignition time may be given by a mean value of the anticipated ignition time and a plurality of the preceding ignition times.

摘要： An ignition system for an internal combustion engine comprises knock detecting means for detecting knocking of the engine, and ignition timing control means for controlling the ignition timing of the engine in response to the presence or absence of the knocking condition. The knock detecting means detects the pressure in the cylinders of the engine to detect the occurrence of knocking by the fact that the detected pressure includes a high frequency pressure variation. The ignition timing control means is responsive to the output of the knock detecting means, whereby as long as no knocking is detected the ignition timing is controlled to provide the minimum advance for best torque (MBT) and ensure improved engine power efficiency and fuel consumption, whereas when knocking is detected the ignition timing is retarded in relation to the minimum advance for maximum torque (MBT) to prevent the engine from knocking.
