IPC: F04B41/04
Filed: 1980-04-30
Abstract: PURPOSE: To prevent a firing hazard of unburunt fuel in an exhaust pipe, by switching muffler and filter side selector valves with a time lag and preventing the unburnt fuel in a cylinder from being mixed into compressed air.  
     CONSTITUTION: With the lapse of preset time, operation of a timer means 9 closes a valve 2a, opens a valve 2b and switches a valve 2. In accordance with switching operation of the valve, high pressure air delivered from each cylinder of a cylinder block 12a is selected to flow in from a branch pipe 3b to a branch pipe 3a and fed into a filter 5. During said period the high pressure air is promotively cooled by a fin 4 and the periphery of the filter 5, further removed its free carbon and oil mist by the filter 5 then delivered to an outflow pipe 52, consequently the unburnt fuel in a cylinder is not mixed into compressed air to eliminate its firing hazard in an exhaust pipe.

Title: Demodulator
Inventor: MURATA HIROYASU
IPC: H04L27/22
Filed: 1985-03-20
Abstract: PURPOSE:To decrease the scale of a circuit by providing a frequency band shift circuit of a reception signal to the pre-stage of a demodulator to convert a ratio of a sampling frequency to a frequency of a demodulation carrier in the demodulator to a prescribed value. CONSTITUTION:A frequency shift circuit 10 consists of a tone input section giving a prescribed input to an output of an A/D converter 11 and a tone input having a frequency corresponding to a carrier frequency of the output of A/D conversion. A demodulation circuit 12 gives a prescribed carrier frequency to the A/D conversion output or a band-shift signal. Since the signal is subjected to band shift by the frequency band shift circuit 10 and the ratio of the carrier frequency to the sampling frequency is limited to a prescribed value, the arithmetic scale in a roll-off filter 13 is reduced.

Title: Overcurrent protective circuit
Inventor: YANAGISAWA RYUICHI
IPC: H02M3/28
Filed: 1988-03-11
Abstract: PURPOSE:To bring an overcurrent detecting point into coincidence with a transfer point from a constant-voltage characteristic to a constant-current characteristic by level-comparing by using a level comparator an error voltage with an output current detection signal, and transmitting an overcurrent alarm signal when an output current detection signal becomes the error voltage or more. CONSTITUTION:When an output current I0 exceeds a rated current It, a power source is shifted from constant-voltage characteristic to constant-current characteristic, and a voltage VA1 is raised to a level range III corresponding to an increase in the current I0. On the contrary, a voltage VA2 becomes a low level smaller than the minimum value of a triangular wave (a) of a triangular wave generator 6 upon abrupt drop of an output voltage V0. Accordingly, a comparator 16 outputs an OCA signal of a high level at this time. Thus, an OCA detecting point can be brought into coincidence with a point of shifting from the constant-voltage characteristic to the constant-current characteristic.

Title: Rotary head drum
Inventor: MIYAZAWA OSAMU
IPC: G11B21/10
Filed: 1984-03-27
Abstract: PURPOSE:To improve the durability of a rotary drum with no generation of sparks and to give no adverse effect to a magnetic circuit for record/reproduction of signals as well as to the revolving performance of a drum, by using a piezoelectric oscillator and a rectifying device at a feed part to an actuator consisting of a piezoelectric element, etc. CONSTITUTION:When a piezoelectric oscillator 3 has a distortion as shown by a broken line, the electric charge is produced by a piezoelectric phenomenon. Thus the electric charge flows into a rectifying device 4 in the form of an alternating current in case said distortion occurs repetitively. This electric charge is turned into an alternating current of frequency fr as long as the oscillator 3 is oscillated by the resonance frequency fr and rectified by the device 4 to be applied to an actuator 5. The displacement amount of the actuator 5 is varied by the applied voltage, i.e., the amplitude of the oscillator 3. Therefore the displacement of the actuator 5 can be controlled with control of the amplitude of the oscillator 3. Thus the actuator 5 for automatic tracking can be driven with no contact. This can avoid the deterioration of durability due to the friction, an evil effect to be given to the revolving performance of a drum and the generation of sparks for a rotary head drum.
