Abstract: PURPOSE:To provide a range measuring device which is simple in circuit constitution, low in cost, and high in performance by measuring a distance to an object to be photographed, basing on the output results from an optical current signal amplifying means. CONSTITUTION:First a switch 7a is turned on and a switch 7 is turned off to amplify an optical current signal received by a photo diode 3b in a light receiving amplifier 9. Next the switch 7a is turned off and the switch 7 is turned on to amplify the optical current signal received by the photodiode 3a in the light receiving amplifier 9. Then, an A/D converter 10 makes A/D conversion of the optical current signal at a specified timing in synchronous with the infrared light emitting action, and the converted signal is input into a CPU 11. Also it is judged basing on the converted signals and by the CPU 11 which signal value is larger among optical current signals from the photo diodes 3a and 3b. Basing on the judgment results, a relative distance to an object to be photographed 14 is measured, i.e., the distance to the object to be photographed is determined.

Title: Relieving device of standby current defect of memory element
Inventor: RIN YUNNHO
IPC: G11C29/04
Filed: 1992-10-23
Abstract: PURPOSE: To prevent defective stand-by current by selectively turning on and off a transistor for a ground selector provided serially to the transistor of a string with an address decoding signal so as to eliminate a current path to the ground at the time of stand-by. CONSTITUTION: Trm7 is serially provided for the transistors(Tr) m1 to 6 of strings ST 1 to n constituting a NAND cell array. This Trm7 selectively turns on and off the current path between Trm5 and m6 with a ground string selecting signal GSS. Tr selected by word lines W/L1 to n, bit lines B/L1 to n and ST selecting signals SS 1 and 2 forms a current path at the ground. However, a signal GSS turns off Trm7 at the time of stand-by and turns on it at the time of a reading mode at need. Thereby the increase of current due to the breakdown of the memory element at the time of stand-by is reduced to prevent the defective stand-by current.
