Abstract: PURPOSE:To reduce the power consumption of a solid-state oscillator, by providing a synchronous holding circuit which intermits the power supply to the solid- state oscillator by a pulse and holds the crest value of a detected output of mixed waves of the output of the oscillator and a received radio wave during each pulse cycle. CONSTITUTION:The power supply from a power source 2 to a solid-state oscillator 1 is intermitted by pulses (a) of a pulse generator 4, and the solid-state oscillator 1 oscillates for several tens mus with several ms cycle. Received waves R transmitted from an antenna 5 and reflected by a moving object 6 are mixed with a part T of the output of the oscillator 1 in a detector 7 and is subjected to synchronous detection by a delayed pulse (b) attained by delaying pulses of the pulse generator 4. This detection output (c) has the crest value held during each pulse cycle by a synchronous holding circuit 9 and becomes an output (d). This output (d) is converted to sine waves (e) by a waveform processing circuit 10 and is supplied to a display part 11. Then, the power consumption of the oscillator 1 is reduced to several % of that for continuous operation, and the oscillator 1 is prolonged in life and made economical.

Title: Circuit for protecting sector mark detection
Inventor: KARAKIDA SHIYOUJI
IPC: G11B20/10
Filed: 1987-09-01
Abstract: PURPOSE:To supply a synchronizing signal with a satisfactory timing even when a sector mark can not be detected by delaying a sector mark detecting signal and a digital reproducing signal only for the same time in a delay circuit. CONSTITUTION:The sector mark detecting signal from a sector mark detecting circuit 1 is delayed for a constant time by first delay circuit 9 and 10 and outputted and the synchronizing signal is outputted from a synchronizing signal generating circuit 7 with the same timing as the delayed sector mark detecting signal. The digital reproducing signal from a disk is also delayed by the second delay circuit for the delaying time of the first delay circuits 9 and 10. Thus, even when the sector mark can not be detected, a synchronizing signal Y0 can be generated at a position where it should appear originally.

Title: Constant voltage circuit
Inventor: SUGANO MUNEYOSHI
IPC: G05F1/56
Filed: 1991-08-29
Abstract: PURPOSE:To attain the sure rise of the output voltage when the output of a constant voltage circuit is changed to an open state from a short circuit state. CONSTITUTION:When the output terminal of an output transistor TR 56 is short-circuited, an auxiliary TR 63 starts working and the output short circuit current of the TR 56 is added to the auxiliary current of the TR 63. Thus the output short circuit current is never equal to zero despite its fluctuation owing to the temperature characteristic of a constant voltage circuit. Then the output terminal l voltage of the TR 56 can surely rise even if the output terminal of the TR 56 is changed to an open state from a short circuit state.

IPC: B26B19/04
Filed: 1988-09-01
Abstract: PURPOSE:To improve the cutting quality by rotatably fitting an eccentric cam shaft fitted with a rotary shaft of a motor into a fitting hole on a drive aiding plate and by rotatably fitting a sub-pivot into a hole for the sub-pivot bored on a trembler. CONSTITUTION:A trembler 12 is provided, which transmits the driving of a motor 3 to an inner edge body 38. A drive aiding plate 19 connecting the trembler 12 and an eccentric cam shaft 9 fitted with a rotary shaft 10 of the motor 3, forms both a fitting hole 21 which rotatably fits the eccentric cam shaft 9 through an elastic thin part 20 on one side thereof and a sub-pivot 23 which is rotatably fitted into a hole 16 on the trembler 12 on the other side thereof and prevented from falling off by an E type of snap ring. When the eccentric cam shaft 9 is eccentrically moved by driving of the motor 3, straight reciprocation is transmitted to the sub-pivot 23 on the drive aiding plate 19 by using the elasticity of an elastic arm 20. Though the movement of the sub-pivot 23 produces some discrepancy between the movement of the drive aiding plate 19 and the ideal reciprocation of the trembler 12 by the deformation of the elastic arm 20, this discrepancy is compensated by the rotary motion to the hole 16 for the sub-pivot 23 and the reciprocation of the trembler 12 approaches to an ideal movement.
