Title: Pyroelectric type thermal detector
Inventor: TAGASHIRA HIROSHI
IPC: G01J5/34
Filed: 1988-02-19
Abstract: PURPOSE:To remarkably increase an output and to improve the S/N by connecting in series two pyroelectric elements whose polarization directions are different and connecting its series coupling point to a gate electrode of an FET. CONSTITUTION:Two pyroelectric elements 1, 2 whose polarization directions are different are coupled in series like a bridge and connected between positive and negative terminals 8, 9 of a power source, and its series coupling point 4 is connected to a gate electrode of an FET 3. Also, a drain electrode of the FET 3 is connected to one terminal 8, and a source electrode is connected to the other terminal 9 through a source resistance 6, and also, led to an output terminal 7. In this state, when heat ray of long wavelength is made incident simultaneously on the elements 1, 2 or cut-off, one element 1 is electrified in the positive direction and the other element 2 is electrified in the negative direction, therefore, the potential of the coupling point 4 is varied, and its potential variation is brought to impedance conversion by the FET 3, and can be led as a large signal to the terminal 7.

Title: High-voltage stabilizer
Inventor: KATAOKA TERUO
IPC: H04N3/185
Filed: 1980-03-18
Abstract: PURPOSE:To reduce the capacity in terms of electric power and to prevent regulation from deteriorating by obtaining high-voltage power from two high-voltage generating circuits and by balancing those electric power outputs without reference to load fluctuations. CONSTITUTION:Owing to variance in the boosting ratio of FBT, the voltage of FBT61 is to rise above that of FBT74, and a load current is also to increase. Consequently, voltage V1 at one input terminal of operational amplifier 41 further drops negatively and amplifier 41 develops voltage V0. This voltage V0 permits the base potential of transistor TR50 to rise through resistance 56. Therefore, negative feedback is provided to decrease emitter voltage E1 of control TR48, and the output of transformer 61 is to decrease, exercising control until current IB1=IB2 (IB1 and IB2 are currents of transformers 61 and 74).

Filed: 1985-02-25
Abstract: PURPOSE:To prevent a projection from generating when a groove is formed by cleaning an Si substrate with aqueous fluoric acid solution prior to dry etching of the substrate after opening a window at an insulating layer. CONSTITUTION:A silicon substrate which has an insulating layer made of an oxide is locally etched to form a groove on the substrate. In this case, after a window is opened at the layer, the substrate is cleaned with aqueous fluoric acid solution prior to the dry etching of the substrate.

Title: Synchronous multiplex system
Inventor: KAMATA YOSHINOBU
IPC: H04J3/17
Filed: 1984-02-27
Abstract: PURPOSE:To suppress consecutive information bit 0s at input interruption by supervising N-set of inputted staff signals and using a special pattern in case of the input interruption to apply synchronism multiplexing. CONSTITUTION:Staff synchronism circuits 7, 8, 9 input respectively two low- order group signals, generate staff synchronizing signals A, B, C subjected to duplicatedly multiplexing and input them to input interruption detecting circuits 15, 16 and 17 in synchronization with a clock dividing a click from a high-order group clock generator 10 into 1/3 by a 1/3 frequency divider circuit 11. The circuits 15, 16, 17 supervise respectively the input of the signals A, B, C give an output to a synchronism multiplexing circuit 12 as it is when an input exists, and when the input interruption is detected, and special pattern from a special pattern generating circuit 14 is outputted to the circuit 12 in place of the input staff synchronizing signal immediately. The form of the special pattern signal is decided so as to decrease information bits 0 as less as possible. Thus, when the staff synchronism signal is interrupted, the consecutive 0s are suppressed and the clock is extracted easily by the reception side.

Title: Method and device for selecting grain
Inventor: YAMAMOTO SOICHI
IPC: B07C5/342
Filed: 1990-02-16
Abstract: PURPOSE:To separate only the grain having a preset major axis from the grains by optically measuring the major axis of the grain. CONSTITUTION:The grains 14 are ordered in a fixed direction by a chute 26 and moved in a specified direction. Light is emitted from a light emitting element 34 in the direction crossing the moving course of the grain 14, and the light reflected or interrupted by the grain 14 is received by a light receiving element 36. The received light is transduced into an electric signal and outputted. An air injection gun 46 is arranged on the downstream side of the chute 26 to deflect the moving course of the grain 14. The major axis of the grain 14 is measured by a controller 44 based on the electric signal from the light receiving element 36, and the gun 46 is controlled so that the moving course of the grain 14 is deflected in accordance with the major axis. As a result, only the grain having the preset major axis is separated from the grains.

IPC: H01J29/28
Filed: 1984-02-29
Abstract: PURPOSE:To prevent any accident of inferior conduction at high voltage by forming a conductive graphite film on a metallic film formed by vapordeposition on the peripheral irregular surface of a phosphor film which is formed on the inner surface of a bulb panel and extends to the slant inner surface of the reinforced area. CONSTITUTION:A fluorescent film 2 and an aluminum film 3 are formed on a bulb 1a which has a reinforced area, the inner surface of which is oblique to the screen portion, between the screen section and the side section.

Abstract: PURPOSE:To provide an illuminator of which a lead wire can be led out with simple constitution. CONSTITUTION:A reflector 10 is composed of a front reflector and a rear reflector 12. In the rear reflector 12, a circular positioning projection 54 to be positioned in the front reflector is made around the periphery, and a storage groove 55 in which to arrange a lead wire 47 for leading around is made on its inner periphery side.
