Title: Differential amplifier
Inventor: ENDO YOICHI
IPC: H03F1/52
Filed: 1989-06-09
Abstract: PURPOSE:To prevent the deterioration in the noise characteristic and the input characteristic of a readout circuit by connecting plural protection diodes in series between two input output terminals and a constant voltage source, using the input and output terminals as anodes and the constant voltage source side as a cathode. CONSTITUTION:When a positive induced voltage at a terminal T1 is applied and reaches nVF+Eb or over, diodes D11-D1n are energized and the inductive voltage is clamped to nVF+Eb. When a positive inductive voltage at a terminal T2 is applied and reaches nVF+Eb or over, diodes D21-D2n are energized to clamp the inductive voltage to the voltage nVF+Eb. When the voltage nVF+Eb is selected to be smaller than the breakdown voltage of the base-emitter junction of transistors(TRs) Q1, Q2, the breakdown of the base-emitter junction of the TRs Q1, Q2 is prevented by the clamping operation.

Abstract: PURPOSE:To comprehend the condition objectively and to express that by enabling detection of the forming condition by a length of a pattern by forming the pattern by using a mask having a linear pattern whose width becomes thinner from one end to another. CONSTITUTION:A light transmissive part of linear form 3 is arranged between a pair of light shielding parts of strip form 2a and 2b and a width of the part 3 becomes narrower from right to left stepwise, e.g. by 0.1mum each. Notches 4a and holes 4b arranged in constant intervals in the light shielding part 2b function as scales. The linear pattern 3 of mask 1 is formed corresponding to a plurality of chips which are different in one sheet of photomask 1 such as a scribe line 6 of a wafer 5 or corners of chips 7a.... When a positive resist on the mask 1 is exposed with changing a quantity of exposing light for each chip, a length of the formed linear pattern differs according to the quantity of exposing light and a condition of forming patterns is better as it is longer. The quantity of exposing light of the longest pattern is determined to be the optimum value and a lot is processed under the same condition. By this constitution, individual variations do not occur in the decision on the forming condition and the condition can be comprehended properly.

Title: Liquid-crystal display unit
Inventor: MIYOSHI TAISUKE
IPC: G02F1/13357
Filed: 1977-12-08
Abstract: PURPOSE: To obtain an excellent display with the entire unit made thin by equipping the observation side of a liquid-crystal cell with a reflective film.  
     CONSTITUTION: At the obervation side of the display body provided with liquid- crystal cell 1, passive reflector 2 arranged under it and lamp 3 adjacent to the flank of the passive reflector, armor 4 is placed, by which the view region of the display part is determined. Then, passive reflector 5 is arranged, without the view region, over cell 1 and under armor 4. The light of the lamp is therefore reflected by passive reflector 5 first, is reflected again by passive reflector 2 after transmitting cell 1, and reaches eyes of an oberving person via cell 1. As a result, since passive reflector 2 only reflects the light from the upper part, a thin metal plate can be employed, and the reflective film can be obtained only by vapor-depositing metal on the top surface of cell 1 under vacuum. In this way, the unit is made thin and a double image due to the thickness of the transparent part of passive reflector 2 can be prevented from appearing.

Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To achieve energy savings by providing a transmission control means which intermittently transmits transmit waves at a predetermined frequency and a frequency setting means which sets the frequency according to the time measured by a timer means. SOLUTION: When a power source is turned on, a microcomputer 29 turns on a transistor 15 to actuate a sensor circuit 13 to effect projection of light from a light projecting element 8. When light is received by a photocell 11 and an automatic faucet is not discharging water, the microcomputer 29 transmits electricity to an H-bridge circuit 27, and drives a valve to open it to start discharging water; when light is not received while the automatic faucet is discharging water, the microcomputer 29 drives the valve to open it. The microcomputer 29, when making sure that the faucet has not been used at the current time zone for a predetermined number of days according to a 24-hour timer, sets the period of light projection longer, judging that the faucet is unlikely to be used.  When the predetermined number of days has not been reached, the microcomputer 29 sets the period of light projection shorter, judging that the faucet is likely to be used. Therefore, energy savings can be accomplished.
