Title: Fuel injector
Inventor: TERADA TOMOHIKO
IPC: F02M47/00
Filed: 1982-02-25
Abstract: PURPOSE:To facilitate the control of period of fuel injection, by only displacing a first and a second control valve againt springs to shift the valves from the closed position to the open position to switch the supply of high-pressure fuel to a fuel pressure intensifier. CONSTITUTION:When a fuel injector starts injection, the plunger 42 of a first pressure generator 40 begins compression. The time of the beginning of the compression is determined by the lead 45 of the plunger 42. For that reason, the time of the starting of the injection can be optionally controlled by moving a control rack 48 to turn the plunger 42. A second pressure generator 67 includes a plunger 70 oil-tightly and slidably fitted in a barrel 68. The plunger 70 is provided with a lead 73 on the top. The lead 73 acts for augmentation as it goes forwards. The plunger 70 is turned by a control force from a control rack 75 through a control sleeve 74 to select a lead position to regulate the end of the injection.

Inventor: KUME TAKEO
IPC: F02B33/36
Filed: 1987-02-13
Abstract: PURPOSE:To restrain an increase in air intake volume and prevent a sharp rise or drop in engine speed by closing a ventilation passage and shutting off a clearance near the bearing of a supercharger from the atmosphere. CONSTITUTION:In controlling the ventilation of a supercharger, an electric control unit 20 first makes judgment as to whether an engine 10 is under starting operation, on the basis of detected signals from a starter switch sensor 32 and an engine speed sensor 31. And when the engine 10 is under starting operation, a ventilation valve 29 closes and a clearance between a housing 16a and a rotor 16b in a supercharger 16 is shut off from the inside (atmosphere) of an air intake pipe 12 at the upstream of a throttle valve 15.

Title: Driving circuit of ultrasonic motor
Inventor: SHIMIZU MASAO
IPC: H01L41/04
Filed: 1986-02-13
Abstract: PURPOSE:To eliminate uneven rotation by conducting a feedback control of a phase difference of frequency voltage applied to a driving electrode so that said phase difference relation will become a prescribed relation, and by locking said phase difference relation. CONSTITUTION:A pulse from VCO 5 is frequency-divided by a frequency divider circuit 19 and applied to an electrode 1-1 through an amplifier 7 and a coil 10. From a multiplexer 21, on the other hand, a pulse of the output end of a register 20, that is, a pulse 90 deg. deviated from the pulse of the frequency divider circuit 19 is applied to an electrode 1-2 through an amplifier 8 and a coil 11. If a driving waveform to the electrodes 1-1, 1-2 does not retain a 90 deg. phase difference, an output of the multiplexer 21 is changed by a counter 22. During the process where the 90 deg. phase difference control is conducted, a processor 26 obtains the average value of a phase difference relation changing in conformity to a feedback control and locks the phase difference relation at this average value.

Title: Gas sensor
Inventor: YAMAMOTO MINORU
IPC: G01N27/12
Filed: 1983-02-24
Abstract: PURPOSE:To make a gas sensor compact as the whole and to enhance noise resistance, by providing a gas detecting part comprising a metal oxide semiconductor of which the resistance is changed by a gas concn. and a CR oscillation circuit containing the same as a resistance element on an insulating substrate by a membrane forming method while providing a temp. sensitive part, a heater part and a heater control circuit thereon by the same method. CONSTITUTION:When the resistance value of a gas detecting part 2 is changed by the reaction with reductive gas, the output frequency of an oscillation circuit 51 is changed corresponding to the change of said resistance value and taken out to the outside through a filter circuit 52. At this time, the output voltage of an inverter 511 applied to the gas detecting part 2 is changed in a pulsated state at the same frequency as the above mentioned output frequency. Therefore, the life of the detecting part 2 is improved to a large extent as compared with such a case that DC is continuously applied. In addition, because the resistance change of the gas detecting part 2 is taken out as the frequency change of a pulse signal, noise resistance is excellent. Furthermore, by providing a vent hole 1a to a substrate 1 so as to partition the upper half and lower half parts thereof, heat transfer is prevented and the deterioration of circuit elements is prevented.

Abstract: PURPOSE:To prevent counting-up from being started by a hard reset signal and to enable operations by the first hit signal at the monitor timer circuit to detect the run-away of a program. CONSTITUTION:An AND circuit 3 inputs the set output of an SR flip-flop 1 and the inverted output of an n-aray counter 2, and the output is inputted to the ENA terminal of the n-aray counter 2 and an AND circuit 4. Then, the hit signal is defined as the set input of the SR flip-flop 1 and the other input of the AND circuit 4. The output of the AND circuit 4 is defined as the input of an OR circuit 5. The hard reset signal is defined as the reset input of the SR flip-flop 1 and the other input of the OR circuit 5. Thus, until the hit signal is inputted after hard reset, the n-aray counter 2 stops the count-up operation and starts the count-up operation from the first hit signal.
