Title: Logical circuit
Inventor: FUJII TAKASHI
IPC: H03K19/018
Filed: 1982-12-07
Abstract: PURPOSE:To stabilize always an I<2>L circuit by connecting odd-numbered gates to one external circuit and even-numbered gates to other external circuit to make an injecting current constant at all times regardless of the logical state of the gates. CONSTITUTION:Inverters Q5, Q6 are provided additionally and an external circuit 12B supplying a current almost the same value of current as the flowing from an external circuit 12A to an inverter Q4 when the inverter Q6 is turned on, is connected to an output of the inverter Q6. When an input to an inverter Q3 is, e.g., at a high level in such constitution, an output of the inverter Q4 goes to high level and an output level of the inverter Q6 goes to low level. When the input of the inverter Q3 is at low level, the output of the inverter Q4 goes to low level and the output of the inverter Q6 goes to high level. Thus, a constant current flows from any one collector of the inverters Q4, Q6 regardless of the logical state, thus making the injecting current constant at all times.

Inventor: KOIDE SHIRO
IPC: G02F1/1343
Filed: 1991-07-31
Abstract: PURPOSE:To facilitate the pattern recognition of the liquid crystal device by giving a stereoscopic effect to a display pattern. CONSTITUTION:First and second segment electrodes 24 and 26 are formed in an inter-digital shape and the 1st segment electrode 24 is formed at a 1/2 pitch at the center part of a common electrode pattern and made narrow at the upper and lower end parts of the pattern.

Abstract: PURPOSE:To realize an external direct access to each peripheral function circuit in a one-chip microcomputer, by adding a bus separation control circuit. CONSTITUTION:The bus separation gate circuits 30a-30f are added to a core CPU 12a of internal bus 22 and the input/output parts of peripheral function circuits 16a, 18a and 20a respectively.
