IPC: G11B17/035
Filed: 1983-06-13
Abstract: PURPOSE:To reproduce several different types of optical disks with just a single reproducer by pressing selectively clampers for a large and small diameter to a turntable and therefore chucking the optical disk of a different diameter to the same driving rotary shaft. CONSTITUTION:An arm 4b which supports a roll rubbing the perpheral part and the recess part 11a of the 1st cam plate 11 is fixed to the rotary shaft 4a of a clamp mechanism 4 together with an arm 4c which supports the shafts 5a and 6a of clampers 5 and 6 respectively. When the plate 11 is rotated toward an arrow A, the arm 4b and the shaft 4a are turned counterclockwise. Then the shaft 6a reaches a point P of a lever 10. In this case, the 2nd cam plate 12 is also turned counterclockwise. Then the position of the point P moves up by a taper surface 12a to push up the shaft 6a. Thus the clamper 6 is pressed to a turntable 2. Then the clamper 5 is pressed to the table 2 by reversely rotating the plate 11.

Title: Control method of converter
Inventor: OKUZAWA KATSUHIRO
IPC: H02M7/797
Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To reduce the losses caused by a switching element with its stable operation, by keeping constant the ratio of a modulating wave to a carrier, controlling the power factor at 1, and performing constant-DC-voltage control. SOLUTION: The control portion of this converter has a dead-time adjusting circuit 21 as well as a PWM control signal generator 12 and a PLL control circuit 10 including a power factor detector 9. One arm, which is connected to a phase with the minimum and maximum absolute value of a three-phase AC voltage, controls a switching element in PWM to suppress higher-harmonic currents. Also, the other two phases are commutated continuously to give to this converter a DC voltage characteristic similar to the diode-bridge converter. Then, when the DC voltage is increased, the PLL control circuit 10 detects a power-factor angle from the power supply voltage and AC current and adjusts the value of the power factor to 1.  On the other hand, the dead-time adjusting circuit 21 adjusts the value of a Y-axis component from the input AC current and the power-factor angle of the power factor sensor 9 to make the vaue zero. Thereby, stable operation is maintained and the losses of the switching element can be reduced.
