Title: Driver of vibrator
Inventor: HASEGAWA KAZUO
IPC: G01C19/5776
Filed: 1999-10-12
Abstract: PROBLEM TO BE SOLVED: To make lockable again the frequency of detection signal by preventing a drive frequency from locking in antiresonant frequency of a vibrator even if the drive frequency offsets in higher frequency zone than the antiresonant frequency of the vibrator by disturbance. SOLUTION: The control signal SI of VCO15 is monitored from a control means 20 having a comparator with hysteresis. In the case the control voltage VI becomes a voltage corresponding to a higher frequency zone than the antiresonant frequency of a vibrator 11 exceeding the upper limit value of the hysteresis, the control means 20 temporarily lowers the control voltage VI. By this, the drive frequency SD is forcedly changed to lower frequency than the resonance frequency of the vibrator 11, a locking of the drive frequency SD to the antiresonant frequency of the vibrator 11 is prevented and detection signals SK1 and SK2 can be locked again.

Title: Integrated circuit for controlling time stroke
Inventor: UCHIGASAKI HIROAKI
IPC: G04G13/00
Filed: 1986-12-06
Abstract: PURPOSE:To simplify designing and manufacture by switching time signals outputted to a stroke number control circuit when a counter specifying signal is outputted and when not, and developing a circuit only by designing one circuit. CONSTITUTION:A time counter 2 receives a just o'clock detection signal and outputs a 1st time signal. A timing signal generating circuit 4 receives the just o'clock detection signal and outputs a time stroke timing signal. A stroke number control circuit 14 counts how many times the time stroke timing signal is outputted, and outputs a time stroke stop signal when the counted value reaches the 1st time signal, thereby stopping the output of the time stroke timing signal. Then a 2nd time signal corresponding to a specified time is inputted to code input terminals D1-D4, but when a non-time signal is applied to the terminals D1-D4, a code detecting circuit 20 outputs a counter specifying signal. A time signal switching circuit consisting of a multiplexer 22 outputs the 1st time signal to a circuit 14 when a counter specifying signal is outputted and the 2nd time signal applied to the terminals D1-D4 when not.

Title: Device of phase shift fixed loop type to demodulate frequency-modulated signal
Inventor: PASUKARU REMASON
IPC: H04N5/455
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a demodulator using a phase shift fixed loop which has an improved linearity over a comparatively wide frequency fluctuation range of an input signal in the order of ±10% of a signal center frequency. SOLUTION: In order to linearize a frequency fluctuation of a local oscillator 11 by the action of a control signal Vb, a fluctuation capacitance Cv is realized by an electric module 20.

Title: Protecting method for wiring appliance and wiring appliance with protecting element
Inventor: KAWAMOTO TOSHIHIKO
IPC: H02H5/04
Filed: 1997-10-07
Abstract: PROBLEM TO BE SOLVED: To protect a terminal block from abnormal heating, by connecting an overheat protecting element which is normally open, and is short-circuited and becomes in continuity at the time of abnormal heating of a wiring appliance, in parallel to the wiring apparatus in a wiring path provided with a circuit breaker, short-circuiting and turning on the overheat protecting element, and operating the circuit breaker at the time of abnormal heating of the wiring appliance. SOLUTION: If a terminal block A for fluorescent lamps generates heat and reaches a specified dangerous temperature T deg.C, an overheat protecting element B is short- circuited and turned on. And by its short circuit current, a circuit breaker 4 operates, and power feeding to fluorescent lamps 7 is interrupted. In this case, an input power to a terminal block nearest to a power source becomes maximum usually, since an input power to each terminal block decreases as it becomes remoter from the power supply (a side more distant from the power source S), but the use of the overcurrent protecting element B makes it possible to interrupt power feeding to fluorescent lamps at the dangerous temperature surely, regardless of the input power to each terminal block.  Accordingly, it becomes possible to restrict the range of flow of an overcurrent to a narrow one and the terminal blocks become safer.
