Abstract: PURPOSE:To enable smooth and quiet engagement and disengagement of a rotation power, by a method wherein, in an engine starting device, an electromagnetic solenoid, which deflects a friction roller, is mounted in the friction roller. CONSTITUTION:Upon closing a switch 27, the voltage of a DC power 28 is energized to an electromagnetic coil 21 through a brush 26 and a slip ring 24, and an armature 22 attracts a yoke 20 to protrude a friction roller 18 in the direction of an outer periphery to deflect the roller, which is forced into contact with an outer peripheral surface 31a of a fly wheel 31. Thereafter, a rotation power is generated through energization of an armature 12, and is transferred to a friction roller 13 through a rotary shaft 14 and splines 15 and 17, the fly wheel 31 being turned and energized to start an internal-combustion engine. After starting, by releasing the electromagnetic coil 21 from energization, the friction roller 13 is released from deflection to restore the roller to its original shape, and driving of a DC motor 12 is stopped. This causes smooth engagement of a rotation power, and relieves an impact at starting, resulting in the possibility to improve reliability of a device.

Title: Noise reduction circuit
Inventor: MATSUO YASUTOSHI
IPC: G11B20/24
Filed: 1985-03-13
Abstract: PURPOSE:To prevent the missing of waveform at recording and to reduce smear and residual noise just after a luminance signal edge with a large amplitude at reproduction by taking out a signal being the sum between a recorded luminance signal and an output signal at an amplitude limit circuit as an output signal. CONSTITUTION:A feedback type LPF is formed from a noise reduction circuit 27 by using a subtractor circuit 32, an LPF 33, a subtractor circuit 34, an LIM 35, a coefficient circuit 36, a subtractor circuit 37 and a coefficient circuit 38 as building blocks. A reproduced luminance signal Sa is fed to the one input terminal of the subtractor circuit 32 via the input terminal 14 of the noise reduction circuit 2, one input terminal of the subtractor circuit 34, and one input terminal of the subtractor circuit 37 respectively. Further, since an output signal from the coefficient circuit 38 is fed to the other input terminal of the subtractor circuit 32, the subtractor circuit 32 outputs a signal subtracting the output signal of the coefficient circuit 38 to the other input terminal of which a signal is given from a reproduced luminance signal Sa fed to the one input terminal. Thus, the missing of the waveform due to overshoot at the recording is not generated and the generation of residual noise and smear at reproduction is prevented.

Abstract: PURPOSE:To provide a ZnO element suitable for use in a lightning arrester provided with a gap, by including Bi2O3, and using ZnO whose specific dielectric factor is over 600 and whose restrictive voltage ratios at 1mA/cm<2> and 10muA/cm<2> range 1.4 thru 2.0. CONSTITUTION:It is known that a resistant body chiefly containing ZnO and also including a minor amount of Bi2O3, etc., exhibits an excellent linearity, and the restrictive voltage ratio has generally been flattened between 1mA/cm<2> and 10muA/cm<2> according to any conventional method. Contrary to this common sense, the restrictive voltage ratios at 1mA/cm<2> and 10muA/cm<2> shall be made over 1.4 and below 2.0. The specific dielectric factor of ZnO incl. Bi2O3 shall be kept over 600. This provides easy flowing of current in the minor amperage range, causes flash shortcircuit on the series gap 4 side certainly at the time of cloud-to-ground discharge, and enhances the insulative coordinativeness with an arc horn 1. Also the subsequent stream shutoff characteristic is enhanced due to selecting the V1mA/V10muA to below 2.0.
