Title: Distance detecting apparatus
Inventor: TSUJI TAKAHIRO
IPC: G01C3/06
Filed: 1990-11-30
Abstract: PURPOSE:To improve the accuracy with a simple constitution when the distance is measured by casting a pulse light to an object to be measured, detecting the spot of the reflecting light, integrating the spot for a predetermined time, and outputting pulse-like distance data having the pulse width proportional to an inverse number of the distance. CONSTITUTION:A spot of the reflecting light is received by a PSD 1. Current outputs I1, I2 are output from both ends of the PSD 1, which are amplified by current amplifying circuits 2, 3 thereby to obtain amplified currents I1a, I2a. Since the sum of the voltages between an anode and a cathode of each diode Q1, Q2 is equal to the voltage between an anode and a cathode of a diode Q3 and the voltage between a base and an emitter of a transistor Q4, a collector current I4 of the transistor Q4 indicates a value obtained by multiplying the ratio of the outputs I1, I2 with a constant current I0 of a constant current source 7. The collector current I4 is integrated in an integrating circuit of a comparator 10, a constant power source 11 or the like, so that the distance data corresponding to the current I4 and proportional to an inverse number of the distance can be obtained. In other words, the current ratio is obtained by a single transistor Q4, thereby preventing measuring errors due to the variations of elements.

Title: Semiconductor memory device
Inventor: OTA MASAKO
IPC: G11C11/40
Filed: 1987-12-28
Abstract: PURPOSE:To prevent the interference of data and the mix of noise by providing switching MOS transistors between driver transistors and loads in a differential amplifier for BICMOS sense amplifier and turning off the transistors with respect to a non-selection bit line. CONSTITUTION:A CMOS amplifier 41 on the side of a bit line BL0 and the inverse of BL0 operates as an amplifier, and information on the bit line BL0 and the inverse of BL0 are read by output nodes B1 and B2. The BICMOS differential amplifier 5 which a clock has activated reads information on the output nodes B1 and B2 to output line OL and the inverse of OL. Even if there is a time when driver MOS transistors TRQ3 and Q4 in the CMOS amplifier 42 of non-selection are simultaneously turned on, an inter-output node is completely detached by the switching MOSTRQ13 and Q14. The interference of data between the nodes B1 and B2 does not occur. An incidental capacity between the gates of TRQ3 and Q4 and the nodes B1 and B2 becomes extremely small due to the existence of TRQ13 and Q14 and the mix of noise is also prevented.
