The lens 13 becomes a converging lens in the direction as indicated with the arrow 31, and does not operate as a lens in the vertical direction. A photodetecting area of a photodetector 14 is divided into four, and the reflected light on the photodetector 14 becomes a beam shape which is thin in the direction as indicated with the arrow 31 and long in the vertical direction. Accordinly, the reflected light 11 on the photodetector 14 moves in the direction as indicated with the arrow 31 in accordance with a converging state of an optical beam 4, and a pattern is varied in accordance with a track shift. Accordingly, differential amplifiers 23, 24 output focus and track control signals, respectively, basing on an output of each photodetecting area 35-38 of the photodetector 14.

Title: Gate circuit
Inventor: HOSHI KIMIHIRO
IPC: H02M1/06
Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To prevent a GTO from being destroyed by providing a control circuit for restricting the on-command period of a second switch to the rise period of a reactor current and to the period of an off-gate current. SOLUTION: When the output of an on-signal generating circuit 9 is changed from 1 to 0, an SW 1 is turned off and on the other hand, a pulse generating circuit 20 generates the pulse of a period t3. The pulse is transmitted to an SW 2 through an OR circuit 21 to turn on the SW 2 again. Therefore. an off- gate current rapidly flows into a GTO 3, so that the impedance between the gate G and the cathode K of the GTO 3 is changed from very small value to a very large value to start applying an inverse bias thereto. When the SW 2 is turned off after the period t3 elapses, since the impedance between the gate and the cathode of the GTO 3 is very large as compared with a resistor 17 (R1) or a resistor 18 (R2), an inverse bias voltage becomes nearly [R2/(R1+R2)] × the voltage of a DC power source 5.

Abstract: PURPOSE:To obtain a die cast rotor for an induction motor without having any blow hole by mounting a rotor core having plural slots in molds having annular recessed spaces and charging a molten metal through a gate provided on the inside of the recessed space. CONSTITUTION:A rotor core 11 formed with plural slots 12 is mounted in annular recessed spaces 14, 17 for molding of an end ring formed in a bottom mold 13 and a top mold 16 in such a way that the opening end of each slot 12 faces to the spaces. A molten conductive material is charged through a pin gate 19 provided on the inside of the space 17 in the mold 16 and is cast from the space 17 into each slot 12. Since the pressure of the molten metal decreases in this stage, no blow hole is formed in the secondary conductor formed in the slot 12 and an end ring 21. The seizure of the molten metal is prevented as the molten metal does not strongly contact directly with the inside wall of the mold 13 and the mold 16. The molds 13, 16 are parted upon solidifying of the molten metal and the solidified material in the gate 19 part is cut, then the die cast rotor is removed.
