Title: Circuit for supplying constant current
Inventor: TAMURA YASUTAKA
IPC: G05F3/02
Filed: 1982-12-28
Abstract: PURPOSE:To obtain a constant current supplying circuit having superior constant current properties and low power consumption by inserting a Josephson junction having large dumping at its junction part into a current line in series. CONSTITUTION:The Josephson junction 3 having no hysteresis on current-voltage characteristics has a large differential resistance value less than a gap voltage. A current is supplied from a constant voltage power supply 1 to a load 4 through a resistor 2 and a Josephson element 3. Even if the voltage VOUT of the load 4 is changed, the current IOUT is not almost changed, so that constant current characteristics having large differential resistance are obtained and the current is maintained almost at a constant value until the current IOUT exceeds the critical current.

Patent JP-S60122451-A (JP)
Title: Data transfer system
Inventor: OKONOGI TAKASHI
IPC: G06F13/37
Filed: 1983-12-07
Abstract: PURPOSE:To improve the utilizing efficiency of a common bus by shifting a request to the level lower by one level so as to replace the request of the same level to the request of separate when a module positioned upperstream side from the own module acquires the right of use of the common bus with high priority. CONSTITUTION:When a module 2-i generates an internal request at level ''0'', a signal req0 from the upperstream is a signal not requesting the use of a common bus, an output signal req'0 of the circuit 4 goes to ''1'', the operating request of the common bus of the lowerstream module is suppressed into ''0'' and the own module acquires the right of use of the common bus. On the other hand, when the signal req0 requests the use of common bus, the outut signal req'0 of the circuit 4 goes to ''1'' to suppress the use of the module common bus of the downstream. In this case, the request level is shifted by the circuits 6, 7. When the output of the circuit 6 goes to ''0'', an output of a 2-input AND circuit 7 is brought into ''0'' level and the same operation as the generation of an internal request signal is attained.

Title: Electrostatic capacity type proximity sensor and lock control device using the sensor
Inventor: USUI TOSHIYUKI
IPC: E05B85/18
Filed: 1999-08-16
Abstract: PROBLEM TO BE SOLVED: To provide an electrostatic capacity type proximity sensor having less power consumption. SOLUTION: An oscillation circuit 31 oscillates, for example, at 40 kHz. A resonant circuit 41 causes a resonance at a higher harmonic of 120 kHz which is three times the oscillation frequency. By this, the amount of current flowing through the resonance circuit 41 is reduced so as to reduce a power consumption. Then, when a detected object Q moves closely to a detection electrode 51, the state of resonance varies by an electrostatic capacity Cx produced between the detected object Q and the detection electrode 51 so as to vary an output voltage. The proximity of the object can be detected by monitoring the output voltage.
