IPC: G06F12/00
Filed: 1985-05-23
Abstract: PURPOSE:To execute a highly speedy image processing and to handle the large capacity of frame memory by providing a frame memory, etc., to store an image at the address to make X and Y coordinates of the image correspond to the higher order byte and the lower order byte of the address. CONSTITUTION:The memory area of the program memory corresponds to a bank 0 and the memory of the frame memory corresponds to a bank 1. The lowest order bit only from the address space 0000 of the bank 1 to FFFF is used,and the bit from a bit D1 to D7 is not used. When the reading and writing are executed for the frame memory area, the aces can be executed by making the X and Y coordinates of the image correspond to the higher order byte and the lower order byte of the address as they are and executing the address designation. Namely, when the frame memory is accessed, the bank of the frame memory is automatically selected through a change-over circuit, etc., and the address can be designated as the address equivalent to the X and Y coordinates. Thus, the image information can be processed at a high speed and the comparatively large quantity of the frame memory can be handled.

Title: Protective circuit for semiconductor laser
Inventor: TAKENAKA SHINYA
IPC: H01S5/042
Filed: 1989-05-01
Abstract: PURPOSE:To enable a protective circuit to absorb surges applied to a semiconductor laser irrespective of their frequencies by a method wherein a diode whose conduction voltage is slightly higher than the oscillation voltage of the semiconductor laser is connected. CONSTITUTION:A Zener diode 2 is connected to a semiconductor laser 1 in parallel, and the laser 1 is driven by an alternate current voltage source 3 through the intermediary of a resistor 4. As the forward breakdown voltage of the semiconductor laser 1 is a hundred volts to several hundred volts, the Zener diode 2 of low yield voltage is used to clip a voltage applied to the semiconductor laser 1, whereby the semiconductor laser 1 can be protected against breakdown. Moreover, the Zener diode 2 functions as a low impedance the same as a conventional diode against a reverse voltage to clip a reverse voltage, so that it can protect the semiconductor laser 1 against a reverse surge voltage. Even if the Zener diode 2 is connected to a drive circuit in which a direct current voltage source 3' is employed in place of the alternate current voltage source 3, the same effect can be realized. When a capacitor is inserted in parallel with a diode, a protective circuit can absorb a surge of frequency higher than the switching frequency of the diode.
