Abstract: PURPOSE:To improve the function and the modulation efficiency of a ballistic conduction element and a quantum interfering type transistor by the resonance tunnel phenomenon by the double barrier structure. CONSTITUTION:The emitter of a vacuum electronic element is provided with, for example, a thin wide-gapped potential barrier B4 composed of AlGaAs. A semiconductor layer composed of GaAs is formed on the end side of the potential barrier B4.

Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To restore an oscillating circuit to a normal oscillating state, without interrupting a power supply by stopping discharge of one oscillation capacitor in the case that 1st and 2nd discharge transistors(TRs) are simultaneously conductive due to noise and the oscillation is stopped. SOLUTION: In the case that discharge TRs Q11, Q12 are simultaneously conductive due to noise and the oscillation is stopped, a level of an oscillation capacitor C12, being a collector level of the TR Q12, goes to a low level, An oscillation stop release means 14 detects it to control a base level of the discharge TR Q12, thereby stopping discharge of an oscillation capacitor C11. The oscillation stop release means 14 is made up of NPN TRs Q23-Q26 for detecting a level of the oscillation capacitor C12, a timer capacitor C13 and a resistor R11. At this time, since the oscillation capacitor C12 is in a discharge state, the oscillation capacitor C12 is restored to the normal oscillation state. Thus, the oscillation stop is automatically released without interrupting power.

Title: Distribution type pump
Inventor: RUISU BUI BIRAADO
IPC: F02M41/14
Filed: 1981-12-17
Abstract: A pump including a floating piston (64) mounted in a cavity of a cylindrical body (32) rotated by a shaft (14). A timing chamber (62) and a metering chamber (60) are formed on either side of the floating piston (64). The amount of fuel admitted to either chamber (60, 62) is controlled by a single electromagnetic valve (20). The duration of energization of the valve (20) determines the fuel supply to the chamber (60) from a supply annulus (40) through passageways (82, 84, 86, 88). Upon completion of fuel metering into the chamber (60), the valve (20) is de-energized and the fuel is admitted from the supply annulus (40) into the timing chamber (62) and also by means of a passageway (72) to the opposing faces of a pair of pumping plungers (66, 68) forcing them outward towards a predetermined position. For initiating injection the plungers are forced radially inward by an annular cam (80), thereby increasing the pressure within the timing chamber (62) and displacing the floating piston (64), thereby forcing the fuel out of the metering chamber (60) into a discharge connection.

Abstract: PURPOSE:To satisfactorily and stably record and reproduce video and audio signals at all times by completely correcting skew generated at a head switching point at the time of reproduction by providing a non-signal term at the head switching point where a track changes at the time of recording, thereby record ing the signals. CONSTITUTION:Switching circuits 19a and 19b are driven by head switching signal synchronized with the rotary phase of a rotary head at the time of reproduction from an input terminal 31, the video signal generates at the output of the switching circuit 19a and the audio due to overlap recording generates at the output of the switching circuit 19b respectively separately.
