Title: High voltage switch device
Inventor: TOKUNAGA KIICHI
IPC: H02M1/06
Filed: 1983-08-31
Abstract: PURPOSE:To stabilize the turn-on state of a main switch element independently of a load current by detecting that the load current of a main switch circuit becomes lower than a turn-on holding current to flow an on-gate current to the main switch circuit. CONSTITUTION:GTOs which are self-arc-extinguishing semiconductor switch elements are used as main switch elements 11-1N of the main switch circuit. The GTO11 is turned on by a turn-on signal, and an on-state current is flowed from a capacitor 51 to the GTO12 to turn on the GTO12. GTOs11-1N are turned on successively in this manner. At this time, if the load current is small, the on-gate current is deficient when terminal voltages of capacitors 51-5N-1 become lower than a certain value, and voltages between anodes and cathodes of GTOs12-1N rise transitionally. As the result, a voltage divided by resistances 71-7N-1 turns on FETs 61-6N-1 to complement the on-gate current.

In this case, if RB is set to 0, the integral value is set to LM-Kpes (es is an offset) finally, and integral feedback operation is performed. If RB is set to Kpes, the deviation feedback operation is performed.

IPC: G06F9/48
Filed: 1989-06-22
Abstract: PURPOSE:To save and restore used registers with one instruction at the time of context switching by allowing logical registers and physical registers to correspond to each other on a register management table by a CPU and recognizing the number of used physical registers by a used register number management register. CONSTITUTION:When a call instruction 210 is executed, registers r0 to r2 out of physical registers are assigned to a user stack pointer 107, a user program counter 108, and a user status register 109. When a logical register which the physical register corresponding to is already registered appears in a program, the number of the physical register existing in a register management table 102 is referred to access data in the corresponding physical register. When a call instruction 211 appears, contents of the used register number management table are automatically referred to save contents of seven physical registers r0 to r6. Thus, context switching is performed without taking save and restore of registers into consideration, and programming is facilitated.

Title: Focus detecting method for optical pickup
Inventor: GOTO HIROSHI
IPC: G02B7/28
Filed: 1990-06-19
Abstract: PURPOSE:To stably control the focus by separating an ordinary-ray luminous flux and an extraordinary-ray luminous flux in directions orthogonal to the prism edge of a Foucault prism. CONSTITUTION:A convergent luminous flux is made incident on a Foucault prism 15. The Foucault prism 15 is made of a birefringence material like crystal and subjects the incident luminous flux to prism action and birefringence action. That is, the incident luminous flux is divided into a pair of luminous fluxes 171 and 172 in directions (upward and downward in the figure) orthogonal to the prism edge 150 (directed orthogonally to the drawing) by the action of Foucault prism 15. Since the incident luminous flux has 45 deg. polarization direction in the linear polarization state, the ordinary-ray luminous flux and the extraordinary-ray luminous flux are separated in directions orthogonal to the prism edge 150 by the birefringence action of the Foucault prism 15. As the result, four luminous fluxes, namely, two ordinary-ray luminous fluxes and two extraordinary-ray luminous fluxes are emitted from the Foucault prism 15, and they are convergent, and ordinary-ray luminous fluxes and extraordinary- ray luminous fluxes constitute pairs of luminous fluxes.
