Title: Inverter
Inventor: MATSUMOTO TETSUYA
IPC: H02M7/5387
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To facilitate the control of a neutral voltage within a minute sampling period by a method wherein, after the lapse of time for generating the neutral voltage of each phase since the start of the minute sampling period, the first or fourth switching device of a unit inverter is turned on. SOLUTION: At the starting time of a minute sampling period Ts 1, the output voltage of an inverter is a neutral voltage. The direction of a current is obtained by a means which detects the direction of the current at an inverter output terminal. Further, the adjusted value T1adj of a time T1 for generating a neutral voltage is calculated from the potential difference Vc 1 between a DC power supply potential and a neutral potential and the neutral potential Vc 2 and the obtained time T1 is made to be within the minute sampling time Ts 1. On the other hand, as an output voltage at the starting time of a minute sampling period Ts 2 is a voltage E, a time for generating a neutral potential is kept as a time T2. Thus, from the obtained times T1 and T2 within the minute sampling periods Ts 1 and Ts 2, one pulse with a voltage E is generated to control the neutral voltage.  As a result, the fluctuation of the neutral voltage can be suppressed.

Title: Method for retraction of focus servo, and focus servo apparatus
Inventor: UEHARA MINORU
IPC: G11B7/085
Filed: 1993-12-22
Abstract: PURPOSE:To obtain a retraction method making possible the normal start of focus servo by using and comparing different reference values with an error signal. CONSTITUTION:When an objective lens 1b is moved to increase or decrease a distance between the objective lens 1b and a recording medium 2 monotonously, a reference value-generating means 6 outputs two reference values V1, V2 sequentially approaching a predetermined value. The reference values V1, V2, are between an extreme value at a position closer to an initial position where the lens lb is started to move and tone predetermined value when the lens 1b is in focus. A comparison means 7 compares an error signal output from an error signal-generating means 3 with the reference values output from the means 6. A control means 8 forms a focus servo loop when the relationship of the error signal and reference value V2 i.e., that the error signal is larger (smaller) than the reference value V2 is reversed after the relationship of the error signal and reference value V1 is reversed. Focus servo is normally started.

Filed: 1989-12-14
Abstract: PURPOSE:To prevent a write reset pulse superimposed on a read reset pulse by setting a time when the write reset pulse arrives, setting a time when the read reset pulse arrives, finding width between them, and delaying the read reset pulse when the write reset pulse approaches the read reset pulse. CONSTITUTION:A synchronizing counter part 11 counts a clock 1, and generates a carry-out signal when full counting is performed, and it is inputted to a set/ reset monitoring part 12 as a reset signal. Meanwhile, the set/reset monitoring part 12 is set with the write reset pulse synchronized with a clock 2, and is reset with the read reset pulse. The width between set and reset is counted with the clock 2. A read reset processing part 13 supplies a control signal to delay the generation of carry-out to the synchronizing counter part 11 when the width is reduced i.e. when the write reset pulse approaches the read reset pulse. Thereby, it is possible to prevent the write reset pulse superimposed on the read reset pulse.
