Title: Feeding period detecting device for intermittent current
Inventor: OZAKI SATORU
IPC: G05F1/10
Filed: 1986-09-11
Abstract: PURPOSE:To detect the feeding period of an intermittent current by providing a means which detects the crest value of the instantaneous waveform of the output current of a converter exceeding a specific value, a means which differentiates the instantaneous waveform, and a means which detects the size of the differentiated waveform exceeding a specific value. CONSTITUTION:A phase control angle command alpha is processed 1 and supplied to a phase regulator 2 through a bus 13 and then an ignition signal G is generated corresponding to the phase signal P of an AC power source V. An SCR 3 performs commutating operation to supply a current (i) to a load 4. A sensor 5 detects the current (i) to generate a signal Vi. The Vi is differentiated 6 and compared with a reference voltage Vei to detect whether or not the current is present, thereby detecting 8 a differentiated signal Vid being larger than a positive reference value Vc2 and also detecting 9 the signal being smaller than a negative reference value Vc3. While the OR result of an OR gate 10 is '1', counting 11 is performed with a reference clock F and the counted value is reset with a trigger signal S synchronizing with the signal G and a counted value theta before the resetting is latched 12 and a processor 1 evaluates the current feeding period based on the theta to compensate current intermittence.

Title: Signal input and output circuit
Inventor: TANEMO SHINICHI
IPC: G11B5/02
Filed: 1981-12-29
Abstract: PURPOSE:To increase the amplitude of an input signal, by providing an input signal  conducting loop from the base to the emitter of a transistor so as to ensure a parallel  shift of potential to each other between the base and the emitter when turning off the transistor for signal output with its base connected to an input/output line. CONSTITUTION:The signal SR which is fed to a recording/reproducing head 1 from a  recording transistor (TR) T1 is supplied to the base of a reproducing TRT2 as well as  to the base of a TRT3 at the side of the reference voltage through an input signal  supply loop. Therefore the voltage V1 of the base of the TRT2 is identical with the  sum of the DC bias voltage E0 and the signal SR; while the voltage V2 of the base of  the TRT3 is equal to the sum of the DC bias voltage E2 and the signal SR respectively.  This means that the voltage higher by an amount equivalent to the difference between  the voltage E2 and E0 is applied to the base of the TRT3 so as to have a shift in  parallel to the base voltage of the TRT2 as the time elapses. Therefore the base  potentials of the TRs T2 and T3 have a parallel shift to each other as long as the  peak potential of the voltage V2 does not exceed the power supply voltage and at the  same time the peak potential of the voltage V1 does not exceed the minimum working  potential of the TRT2.
