Title: Semiconductor type heat sensor
Inventor: MORISUE KAZUNARI
IPC: G08B17/06
Filed: 1988-03-28
Abstract: PURPOSE:To reduce dispersion in sensitivity by comprising a charge circuit by connecting the emitter of a transistor to a capacitor via a first diode, and comprising a discharge circuit by connecting a discharge time constant setting resistor via a second diode set in a direction opposite to the first diode. CONSTITUTION:When an ambient temperature rises moderately, the decrease of potential Vt at the connecting point of a series circuit consisting of a resistor R1 and a thermistor Th is also moderate, and the terminal voltage of the capaci tor C is decreased following the above, therefore, comparators Q2 and Q3 issue no output to a switching circuit Q1. However, when the ambient temperature rises steeply, the potential Vt at the connecting point of the series circuit is decreased steeply, thereby, the voltage drop of the capacitor C due to a dis charge resistor R3 is delayed, therefore, the output of the comparators Q2 and Q3 are issued to the switching circuit Q1, and a thyristor SCR is turned on when the terminal voltage of the capacitor C exceeds the terminal voltage Vt of the series circuit, then, an alarm signal is outputted. In such a way, the dispersion in the sensitivity can be reduced.

Patent JP-S60218758-A (JP)
Title: Low pressure mercury vapor electric-discharge lamp
Inventor: ITOU HIDENORI
IPC: H01J61/28
Filed: 1984-04-13
Abstract: PURPOSE:To enable desired rising characteristics to favorably last over a long period by using a high-melting-point metallic material as a base body to be coated with an indium film. CONSTITUTION:An auxiliary amalgam 20 is installed between a filament 17 and the opening of a fine tube 18. The auxiliary amalgam 20 is prepared by coating a base body 21 consisting of high-melting-point metallic foil with a thin indium film 22 by plating, vapor deposition or similar method. Therefore, even when the auxiliary amalgam 20 is heated to high temperature, due to the high melting point of the base body 21, the base body 21 is maintained stable and almost no alloying reaction proceeds between the base body 21 and the indium film, thereby suppressing the thickness decrease and the deterioration of the indium film. Consequently, it is possible to favorably continue desired rising characteristics of luminous flux until the last stage of the life of the lamp.

Title: Life detector for capacitor
Inventor: MATSUI KOUICHI
IPC: G01R31/01
Filed: 1980-06-03
Abstract: PURPOSE:To detect the life of a capacitor before toxic gas evolves by measuring the capacity of the capacitor and comparing the same with a capacity at the life. CONSTITUTION:Before a capacitor reaches a life, its capacity increases by about 7-8%. An integral network 10 integrates the current flowing in a capacitor 3 and obtains integrated voltage F. When the voltage F and reference voltage V1 coincide, a control signal is supplied to a sample to a holding circuit 12, by which an output H is obtained. The circuit 12 is held applied with C and D which are the voltages before and after closing of a switch 2. The output H indicates the voltage at the time of constant charge and when this voltage is a certain constant value V2 or less, it indicates that the capacity is larger than a reference capacity from the basic equation of C=Q/V. Hence, H is compared with a reference value V2 by an operational amplifier 13, and when it is V2 or less, current flows to a light emitting diode 14, by which light emission displaying is accomplished and the life of the capacitor is detected.

IPC: G01D5/26
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To enable discovering of abnormality in operation by generating an alarm when chattering is caused between a rotating shaft and a bearing of a rotor and when positional deviation of a throttle plate is caused. SOLUTION: A first (second) counter 5 (6) counts the number of pulse signals which is generated from a reference signal generator 8 in proportion to time at which a first phase output signal exists as generated by a first (second) photosensor 55 (58) and no second (first) phase output signal exists as generated by a second (first) photosensor 58 (55). A subtraction means 7 detects the time difference between the first phase output signal from the first photosensor 55 and the second phase output signal from the second photosensor 58. When chattering occurs between a rotating shaft 51 and a bearing 52 of a rotor 53 arranged in an encoder 50 or a positional deviation occurs in a throttle plate 54, the first phase output signal and the second phase signal may vanish at the same timing.  On this occasion, judgment output is generated by a comparison means 9 to generate an alarm with an alarm device 10 to report the abnormality.

Title: Optical deflector
Inventor: OKAMOTO NORIHISA
IPC: G02F1/133
Filed: 1987-03-27
Abstract: PURPOSE:To permit deflection of an incident luminous flux over a wide range where a voltage distribution is formed by forming a titled deflector into the construction in which liquid crystal molecules are oriented parallel with the surface of a base on one base side and perpendicularly to the surface of the base on the other base side when a pair of transparent conductive layers have an equal potential. CONSTITUTION:The orientation of the liquid crystal molecules when respective electrodes are held at the equal potential rises gradually in parallel with the base surface on a polyimide layer 9 side and forms the oriented state perpendicular to the base surface on a chromium complex layer 11 side. The upper electrode is then grounded and one end 12 of the lower electrode receives square wave pulses of + or -3V heater value and 1kHz frequency. The orientation distribution of the liquid crystal molecules when the other end is grounded receives the potential distribution in the lower electrode and changes continuously from a partially oriented state 13 on the ground side to the perpendicularly oriented state 14 at the other end, thus generating a continuous change within the plane of a refractive index. The polarization component of the incident light is thereby deflected over the wide range according to the impressed voltage.
