IPC: G01D5/249
Filed: 1988-06-21
Abstract: PURPOSE:To obtain an output having an S/N ratio twice as large as one of a detector by providing a track of an absolute pattern and a track of an inverted pattern thereof on a code plate, by reading the two patterns and by taking a differential of complementary detection signals of the two. CONSTITUTION:Two tracks 2a and 2b, a first and a second, having an absolute pattern and an inverted pattern thereof respectively are provided as tracks on a code plate 1, and first and second MR element sensors 11 and 12 of a detector 10 are assigned to the tracks respectively. The patterns of the first and second tracks are read synchronously by these two detectors, the first and the second. Signals appearing at output terminals 18 and 19 of the two detectors are subjected to differential amplification in a differential amplifier 24 of a signal processing circuit 21 and a signal shaped substantially in a rectangular wave is obtained at an output end 25. This signal is converted into a rectangular wave at a prescribed comparison level by a comparator 26. Then a signal of a rectangular waveform having sharp rise and fall is obtained at an output terminal 27a of the circuit 21, and this signal is taken as an encoder signal.

Filed: 1980-10-28
Abstract: PURPOSE:To obtain a digital input device of the cnventional type input sense with a simple mechanism, by making it possible to generate output signal by compensating content of pulse interval counting of pulse generating by a rotary input step and also to generate single-shot pulse at the same time. CONSTITUTION:When a knob 111 is rotated, a signal Q is issued from an input step 1 by a drive claw 112 and a piezoelectric switch 12, etc., and pulses are formed by a waveform shaping circuit 2 in accordance with rotation of the knob 111 and impressed onto a control circuit step 3. The step 3 impresses count-starting and ending pulses onto a pulse interval counting step 4, and at the same time, it controls a compensating circuit step 5 and an output signal preparing circuit 6 by its control pulses. By so doing, content of counting is compensated by the number of pulses corrected in accordance with the pulse interval, and the circuit 6, which is designed to generate single-shot pulses, too, generates time-correcting signal for a watch, etc. in accordance with thus compensated content. Therefore, it is possible to obtain a digital input device of the conventional type input sense with a simple mechanism.

Title: Timer circuit
Inventor: YOSHINAGA MAKI
IPC: H03K17/28
Filed: 1983-08-22
Abstract: PURPOSE:To compensate the reduction in a capacitance value by supplying a reference voltage regulated into a constant voltage to a base of a transistor (TR) supplying a charging current. CONSTITUTION:When an input signal IN is at a high level, a TRQ11 is turned on and a capacitor C2 is discharged. When the signal IN is changed to a low level, the TRQ11 is turned off and an emitter current of a TRQ10 is charged to the capacitor C2 through a resistor R10. When the charging voltage reaches the reference voltage Vref, TRs Q12, Q14 are turned on and an output current is supplied. Since the reference voltage Vref regulated into a constant voltage is fed to a base of the TRQ10, a voltage applied to the resistor R10 is made smaller in inverse proportion to the charging voltage VP to the capacitor C2 to compensate the reduction in the capacitance value based on a p-n junction of the capacitor C2.
