Title: Control system for cell buffer
Inventor: YAMAGUCHI TAKESHI
IPC: H04L12/28
Filed: 1995-02-09
Abstract: PURPOSE: To stably control the write-in and read-out to/from a buffer of cell data, regardless of input/output conditions such as a write-in speed and a read- out speed, etc., and to detect the abnormality of an address line. CONSTITUTION: For the cell buffer not shown in the figure, the area of the cell buffer is divided into banks by the area of the integral multiple of one cell. Information holding means 9-1-9-n are provided for the respective banks, signals for indicating the end of the write-in to the banks are held when ending the write-in to the banks and the holding of the signals is cancelled when ending the read-out from the banks. The states of the information holding means are inspected. Thus, buffer overflow, buffer empty and an address line abnormal state are judged.

Title: Microcomputer incorporating eprom
Inventor: NAKAMURA TOSHIMASA
IPC: G11C17/00
Filed: 1986-02-05
Abstract: PURPOSE:To prevent the miswriting to an EPROM by setting forcibly a dynamic circuit which has a malfunction due to irradiation of the light entering through a window into a static state in an EPROM writing mode. CONSTITUTION:A transmission line 7 for control signal of oscillation circuit is provided to stop the working of an oscillation circuit 13 that could not be stopped by the conventional P.S signal. Thus a dynamic circuit of a control part has no malfunction despite irradiation of the light entering through a window by setting the dynamic circuit forcibly (electrically) into a static state. This is because both signals the inverse of phi1 and phi1 are controlled so that the signal of a fixed level is transferred for conduction of the 1st p-type MOSFET 502 and the 2nd N-type MOSFET 505. Thus the charging/discharging of a capacitor 501 can be entirely ignored. As a result, the correct signal (level 1 with phi) is transferred to a switching part where the connection/disconnection is carried out between an ALU 20 and a bus line 1. Then the ALU 20 is completely separated from the line 1 and the program information is written correctly to an EPROM 2.

Filed: 1983-02-15
Abstract: PURPOSE:A novel type of pressure- and heat-sensitive recording sheet which can be used either in heat-sensitive recording or in pressure-sensitive application and also can promote the simplification of business work. CONSTITUTION:A thermal color forming layer containing a combination of a colorless or light color basic dye (e.g., triphenylmethane phthalide series, fluoran series, etc.) and an organic acid or phenolic substance (e.g., solid organic acids such as stearic acid or an acid polymer of these with formalin) is provided on one side of a supporter (e.g., paper). Also, a pressure-sensitive colorant layer of microcapsule is provided on the other side of the supporter to obtain a sheet capable of either thermal recording or pressure-sensitive duplication. By using a chromogenic substance to forming a color different from the pressure-sensitive colorant used for the pressure-sensitive colorant, recording and duplication having different colors can be made on the same surface. The pressure- and heat-sensitive recording sheets are laminated in plural numbers and copying recording can be obtained on each recording sheet.
