Abstract: PURPOSE:To improve efficiency by performing all switching operations with zero voltage or zero current, making use of current and voltage resonance operations alternately, and to reduce the harmonic components of the operation voltage and current waves inside a circuit. CONSTITUTION:When the first switch 1 is turned on, a resonance current in the shape of sine waves flows to resonance means L2 and C2 in series, and the smoothing capacitors C3 and C4 of DC output means are charged. Since the current seeks to be inverted when the resonance circuit passes by a half wave, rectification diodes D1 and D2 are biased reversely, and the resonance path is cut off, and the resonance current vanishes automatically During the on period of the first switching element, L1 excitation and C1 charge accumulation are performed, while resonance is being performed in parallel resonance means L1 and C1. During the zero current period after that, the first switching element is turned off. At the same time, the resonance operation of the parallel resonance means is started, and the output end voltage of the switching means is changed from one voltage to the other voltage, making use of the voltage resonance wave in the shape of sine waves. And while the output end voltage of the switching means is near the other potential, the second switching element is turned on. The first and second elements repeat the above operation.

IPC: H01M10/42
Filed: 1979-12-21
Abstract: PURPOSE: To detect battery life surely without any variance by providing a frequency dividing circuit that does not affect time stepping, dropping the battery voltage, supplying the dropped voltage to said circuit and detecting the frequency dividing abnormality thereof.  
     CONSTITUTION: A frequency dividing circuit D for time stepping is connected to a crystal oscillator Q to drive a motor M; at the same time, a flip-flop circuit F 1  forming a frequency dividing circuit which does not contribute to the time stepping is connected thereto. The voltage slightly dropped from battery voltage VDD by resistances R 1 , R 2  is supplied to this. Hence, if the battery voltage VDD is normal, the flip-flop circuits F 1 , F 2  generate the same pulses and there is no output from a gate circuit G. When the battery voltage VDD drops, the flip-flop F 1  causes frequency dividing abnormality, by which a pulse signal is generated from the gate circuit G. Therefore, the alarming of the time for exchanging the battery may be accomplished surely with the extremely simple circuit.

Title: Magnetic head device
Inventor: SAWAI ATSUSHI
IPC: G11B5/027
Filed: 1994-07-20
Abstract: PURPOSE:To enhance the reliability and the sensitivity on reproduction and to supress the occurrence of deterioration of the signal-to-noise ratio. CONSTITUTION:An IC 16 for amplifying signals from head tips 12 and 13 is mounted on a 1st circuit board 14 connected to the head tips 12 and 13. Consequently, since the weak signals outputted from the head tips 12 and 13 are amplified by the IC 16 positioned close to the head tips 12 and 13, their signal transmitting paths can be shortened, and hence the occurrence of deteriorating the weak regenerative signals from the head tips 12 and 13 can be prevented, and also the signals are hardly affected by crosstalk. Then, since the capacity is reduced by shortening the signal transmitting paths, the number of turns of a coil wound around the head tips 12 and 13 respectively can be increased.
