Title: Semiconductor memory circuit
Inventor: TAKAHASHI HIROYUKI
IPC: G11C11/416
Filed: 1988-10-06
Abstract: PURPOSE:To reduce parasitic capacity and to accelerate a readout operation by dividing a sense amplifier into plural groups, and connecting a pair of read buses to the emitter of a multi-emitter type bipolar transistor comprising a current-voltage conversion circuit at every groups. CONSTITUTION:The sense amplifier 3 is divided into the plural groups, and the wiring pair of the read buses SB1, SB2 or SB'1, SB'2 in respective group are connected to the different emitter terminals of the bipolar transistors T3, T4, or T7, T8 in the current-voltage conversion circuit 4. Thereby, in the amplifier 3 set at a non-selective state which belongs to the same group as that of a selected amplifier 3, the collector capacity of the bipolar transistor functions as a load, however, no signal transmission by the buses SB'1, SB'2 is performed in the group including the amplifier 3', and it does not function as a load capacitor. Therefore, it is possible to reduce the incidental capacitance and to accelerate the readout operation.

Title: Control method for path movement of robot
Inventor: NISHIMOTO KATSUSHI
IPC: B25J9/10
Filed: 1986-10-23
Abstract: PURPOSE:To prevent a robot from being stopped at a passing point, by applying velocity control by velocity vectors toward the passing point and a targeted point, and performing no positioning control at the passing point. CONSTITUTION:The velocity control is performed by the velocity vectors Vdi, Vdi+1, and Vdi+2, from a start point Pio to the passing point Pi, from the passing point Pi to the passing point Pi+1, and from the passing point Pi+1 to the targeted point Po, and the positioning control is performed only at the targeted point Po. Since the velocity control for path movement is performed by using the velocity vector, it is possible to change a moving direction at the passing point according to the velocity vector, and no positioning control is performed. In other words, the coordinate of the passing point is used for the change of the velocity vector, not for positioning. Therefore, it is possible to prevent the robot from being stopped at the passing point unrequired to stop, and also, to smoothly operate each axis (joint).
