Title: Temperature sensor
Inventor: SHIYOUJI MAGOZOU
IPC: G01K11/18
Filed: 1979-04-28
Abstract: PURPOSE: To provide a highly waterproof temperature sensor useful to detect the temperature of a bath or the like, by filling a container with a termosensitive substance which changes from an opaque state into a transparent state at a detected temperature and by inserting a light irradiation member for irradiating light upon the thermosensitive substance and a light receiving member which receives the incident light from the light irradiation member, into the container.  
     CONSTITUTION: A temperature sensor comprises an enclosed container 1 made of a material of high thermal conductivity, a reflector 2 placed on the inside surface of the bottom of the container, a pair of optical fiber units 5, 6, etc. A thermosensitive substance 3 such as heptadecylic acid, which changes from an opaque solid into a transparent liquid when the temperature of the substance exceeds its boiling point of about 60°C, is filled in the enclosed container 1. The substance turns transparent around an objective detected temperature. Light emitted from a light emitting diode LED is transmitted through the optical fiber unit 5. When the thermosensitive substance 3 is transparent, the light is conducted to the reflector 2 and transmitted through the substance and the other optical fiber unit 6 and reaches a phototransistor PT which detects the light.

Title: Fsk demodulator
Inventor: FUJITA SUSUMU
IPC: H04L27/156
Filed: 1978-05-06
Abstract: PURPOSE:To improve the stability of a FSK demodulation circuit on a zero-cross system, by using a clock generator of sufficiently-high frequency stability and a counter. CONSTITUTION:The demodulation circuit is provided crystal oscillator 25 and with counter 26 of sufficiently-high frequency stability, which counts up the frequency of oscillator 25 and is reset by the output pulse of zero-cross detector 10. In the above constitution, FSK signal (a) is converted into output pulse (c) by detector 10. When the oscillation of above-mentioned oscillator 25 is set to a period much shorter than the maximum period of the output pulse of detector 10, counter 26 counts the output pulses of oscillator 25 and generates its output until the discrete value reaches a fixed value, thereby obtaining rectangular wave (e). This output signal becomes demodulated signal (g) by passing through LPF7 and level converter 8. In this way, the demodulator can be obtained which is under no influence of variance of parts and a power voltage.

Title: Preventing maintenance method of circuit breaker
Inventor: NONOMURA TAKESHI
IPC: G01R31/333
Filed: 1978-05-09
Abstract: PURPOSE: To make possible accurate checking of action of the contact at the shut-off section by  two conversions into electric signals comprising one at the high potential section where the situation of the contact the shut-off section is initially converted into an electric signal and the other at  the low potential section where an optical signal is converted into an electric signal by a photoelectric element after transmitted through an optical conductor via conversion of the electric signal  by a light-emitting element after the initial conversion.   
     CONSTITUTION: To convert the action of contacts 4 and 5 at the shut-off section into an electric  signal directly at the high potential section, a voltage dividing capacitor 4 in parallel to the contacts are provided with a voltage dividing capacitor (impedance body) in series to ensure the  voltage required for light-emitting elements 6 and 7 for example when the contacts 4 and 5 open.  Photoelectric elements 10 and 11 and amplifiers 13 and 12 are provided at the low potential section through fibers 8 and 9. Accordingly, while the contacts 4 and 5 are open, light-emitting  element 6 and 7 emit-light so that the optical signal is converted with the photoelectric elements to  an electric signal. In this manner, the action of the contact at shut-off section can be checked  directly on the high potential side, thereby improving the reliability.

IPC: H01L29/78
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To increase drain withstand voltage of a high withstand voltage transistor with high reliability, and increase current driving capability. SOLUTION: An impurity in an impurity region 26 in a channel region 23 compensates for an impurity in an impurity region 25 in an offset drain region to reduce impurity concentration in a part of the impurity region 25 on the side of the channel region 23. For this, a depletion layer is extended into the part having the lower impurity concentration in the impurity region 25, while parasitic resistance is decreased in a part having higher impurity concentration in the impurity region 25. An impurity of the same conductivity type as that of the drain region is introduced into the surface of the channel region 23 to adjust threshold voltage to a desired value.

Abstract: PURPOSE:To achieve uniform temp. distribution by a method wherein the air in a cylindrical body of each flow element is sealed up tightly between a flat plate for the lower plate and the element to act as a heat insulating layer and projections placed at the closed end parts of the cylindrical body provide a fluid passage between the outer wall of the closed part and a flat plate for the upper plate. CONSTITUTION:Each flow element 20 enables its outer wall of a cylindrical body 21 to adhere each other and its open end part to adhere on a flat plate 10 for the lower plate. The upper part side of the element 20 fixes a flat plate 30 for the upper plate by using projections 22. By this constitution, a heat insulating layer 23 is formed by sealed air between each element 20 and the plate 10 and a fluid passage provided by the projections 22 is formed between the outer wall of a closed end part and the flat plate 30. As the projections 22 are located with various relative angles and arrangements in the fluid passage, the fluid is branched off in various directions by the projections 22. As a result, a labyrinth-shaped passage is formed and as the fluid flows complicatedly in the overall region of a panel, uniform temp. distribution is obtained.

Title: Flash photographing device on ttl light metering system
Inventor: OOMORI KOUICHI
IPC: G03B7/16
Filed: 1982-04-02
Abstract: PURPOSE:To discriminate previously propriety of exposure, by providing a dimming level varying means which varies a photographic emission dimming level to a test emission dimming level in interlocking with the closure of a test switch, and performing test light emission. CONSTITUTION:When the test switch 38 is operated, a flash discharge bulb 25 starts the light emission. A transistor 37 turns on and a resistance 34 is short- circuited to vary the uninverted input potential of a comparator 33 to a test emission dimming level different from that when a synchronizing contact 40 is turned on. The quantity of light incident to a phototransistor 32 decreases owing to an obstacle such as a mirror, but the minus electrode potential of an integrating capacitor 31 reaches the test emission dimming level, so the time is unchanged, obtaining the amount of light emission equal to that during photographic light emission. When the comparator 33 outputs a light emission stopping signal, a light emitting diode 41 turns on to display dimming emission, so whether proper exposure is obtained or not is confirmed.
