Title: Electronic timepiece
Inventor: NISHIWAKI ZENJI
IPC: G04C3/14
Filed: 1983-09-07
Abstract: PURPOSE:To stably and reversibly rotate the rotor of a step motor for an electronic time piece, by forming a section such that a current is not flowed to a coil for a definite time at the time of rotation to a reverse direction to apply voltage to the motor. CONSTITUTION:When second pulse voltage is applied at the point of time when a rotor 2 comes to the vicinity of the notches 3, 4, the rotor 2 begins to rotate reversely. A period, such that no inverse induction current flows to a coil when the rotor 2 is accelerated and reversely rotated to reach a position shown by the drawing (d), is set. By this mechanism, the rotor 2 succeeds reverse rotation to a position shown by the drawing (e) by inertia without being subjected to speed reduction resulting from the reception of braking action due to a current flowing the coil. In addtion, when the rotor 2 comes to a position shown by the drawing (e), a third pulse is applied to further rotate the rotor 2 reversely. By this method, the application timing of the third pulse can be also made well and reverse rotation becomes stable.

Title: Control signal reproducing circuit for video instrument
Inventor: ARAKI KYOICHIRO
IPC: G11B15/087
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To make a dynamic range of an input signal large by generating the respective threshold voltage values on the upper and the lower sides of a hysterisis comparator and the reference level of amplitude of the output signal of a current output amplifier. SOLUTION: When an output voltage exceeding the voltage VP of a connection point P is generated in a current output amplifier 11, a gain control circuit 12 generates a prescribed control current value and converges it and performs gain control for suppressing the output voltage by suppressing the output current. Since the voltage VP at the connection point P has a larger value than the threshold level VH in a voltage divider circuit 13. The amplification factor is largely described by performing gain control when the output signal level of the current output amplifier 11 exceeds this value. Consequently, referring to the other voltage dividing resistance, the threshold level VH is set at an arbitrary point and similarly, threshold level VL is set at an arbitrary point within the range lower than the threshold level VH.
