IPC: G09G3/36
Filed: 1988-08-26
Abstract: PURPOSE:To make the light-dark brightness difference between a display dot and a nondisplay dot constant regardless of a display pattern and to make a display image plane clear by making the absolute value of a voltage applied to a liquid crystal panel larger and larger as the quantity of variation of display data of one image plane by a detecting means is larger and larger.

Abstract: PURPOSE:To prevent the troubles due to the trouble of a safety circuit, etc. set alone, by installing a safety anomaly detecting device which is energized if the output of the safety circuit is not generated when a sliding door is opening-shifted. CONSTITUTION:A contact point 16 is closed, and a sliding door 5 is closing- shifted. If a working body 6 is pressed by a passenger at an entrance/exit 1 during the closing shift of the sliding door 4, a detector 9 operates. Since a safety circuit 8 generates an output because of the operation of the detector 9, an AND gate 19 generates an output, and a door closing anomaly controller 20 is energized. Then, the sliding door 4 is controlled through the reverse opening of the door. When the output of the safety circuit 18 is not generated during the opening of the sliding door 4, (even after the working body 6 retreat-shifts), because of the trouble of the detector 9 or the disorder of the safety circuit 18 itself, a NAND gate 21 generates an output. The AND gate 22 generates an output through the output of the NAND gate 21, and a safety anomaly detecting device 23 is energized. Therefore, the countermeasure for safety such as operation suspension of an elevator is carried out.

Title: Temperature detecting method by semiconductor pressure sensor
Inventor: MINAGAWA HIROSHI
IPC: H01L29/84
Filed: 1989-08-19
Abstract: PURPOSE:To detect the temperature of the sensor form the variation in the voltage between both input terminals by using a result that the voltage between both input terminals of the sensor varies linearly in relation to the temperature of the sensor when the temperature of the sensor varies owing to the variation in the ambient temperature of the sensor. CONSTITUTION:The temperature variation characteristics of the voltage between both input terminals of a semiconductor pressure sensor 9 are found previously and inputted to a microcomputer 14, then the voltage is converted by an A/D converter 15 into digital data to derive the temperature or temperature variation of the sensor 9. Even if the voltage between both input terminals of the sensor 9 varies, the voltage between both output terminals of the sensor 9 never varies unless there is pressure variation because of a bridge of piezoelectric resistance elements gamma. Therefore, the temperature is detected from the voltage between both input terminals of the sensor 9 and pressure is detected from the voltage between both output terminals, so that one sensor 9 can be used as a temperature sensor.

Title: Cathode for recovering metal copper and method for recovering metal copper from solution containing hydrochloric acid and copper chloride
Inventor: NAKAGAWA OSAHIRO
IPC: C25C7/02
Filed: 1986-09-12
Abstract: PURPOSE:To efficiently recover metal copper by using the cathode etched with HF and consisting of Ti, Zr, Nb, or Ta, and electrolyzing the soln. contg. hydrochloric acid and copper chloride to deposit metal copper in the form of fine particles. CONSTITUTION:Metal copper and gaseous chlorine are recovered by electrolysis from the soln. contg. hydrochloric acid and copper chloride such as a copper waste soln. In such a method, the cathode etched with HF and consisting of Ti, Zr, Nb, or Ta is used. The cathode is obtained by etching the metal with 5% HF until generation of hydrogen due to the activated dissolution of the metal is remarkably exhibited. Besides, the electrolysis is preferably carried out while keeping loss in the current efficiency at 15-50%. As a result, the fine particles of metal copper having excellent releasability are deposited on the cathode. The fine copper particles can be easily released by the vibration imparted to the cathode, and recovered as a solid-liq. mixture with the catholyte. Accordingly, the exchange and extraction of the cathode and the stoppage of electrolysis can be dispensed with.
