Title: Conductive antireflection film
Inventor: FUKUYOSHI KENZO
IPC: G02B1/14
Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To improve conductivity and visible ray transmissivity and improve moisture resistance and time elapsed stability by footing a transparent oxide thin film of a specific mixed oxide and containing a gold element of a specific value or more in a silver thin film. SOLUTION: A transparent oxide thin film which is composed of ternary mixed oxide containing tin oxide, cerium oxide, and gallium oxide is a conductive antireflection film containing a gold element of 1.5at%(atom percent) and more in a silver thin film. Because addition of the gold element to the silver thin film suppresses the movement of the silver, which is apt to move, without reducing the conductivity and light transmissivity of the three-layer film, it is effective to improve moisture resistance of the three-layer film. Though it is effective to add the gold element 1.5at% or more in the silver, there is the tendency that the increase in addition quantity of the gold element reduces the light transmissivity of the three-layer film and it is also expensive so that the little addition is preferable in view of the cost, for example, 10at% or less.

Title: Earth fault contact detector
Inventor: KOISHI HIDEMITSU
IPC: H02H3/17
Filed: 1978-02-22
Abstract: PURPOSE: To facilitate normally monitoring plural power sources by the procedure in which series circuit consisting of rectifying element and DC power source for detection is connected in the direction of obstructing the outflow of current from power source to be detected and at the same time its one end is earthed in order to obviate the needs for switching operation.  
     CONSTITUTION: When the voltages of the DC power sources 5A11 and 5A12 for detection are set up to smaller ones than that of the DC power source 1A1 to be monitored in case where there is no earth fault or earth fault contact, the rectifying elements 10A11 and 10A12 are in inverse-characteristic state and thus the current flowing in the series circuits 11A11 and 11A12 is zero. The same is true of the AC system. When an earth fault occurred in the DC system, current flows and then detected by the current detector 7A12. In the case of earth fault in the AC system, the current is detected by the current detectors 7B11 and 7B12.

IPC: H04N5/00
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To provide a remote controller improved in operability while saving labor for searching a remote controller suddenly such as when a telephone call is incoming. SOLUTION: A remote volume controller 1, for which an operating function is narrowed into volume control only, having operating buttons 3a and 3b for operating the sound volume of television is used while being stuck on the back of a receiver with a double coated cushion adhesive tape. When a telephone call is incoming to a person watching a television, the sound volume of television can be lowered by the remote sound volume controller 1 stuck on the receiver while answering so that labor for searching, taking and returning the remote controller can be saved and the telephone call can be smoothly dealt with. Further, because of simple structure narrowed into basic function, the operating button can be secured wide so that even the aged or a person disabled in sight can easily perform remote control operation.

Title: Light switch
Inventor: BABA NOBUYUKI
IPC: G02F1/31
Filed: 1993-02-08
Abstract: PURPOSE:To provide a light switch operated by liquid crystal holography and capable of uniformly distributing the light in various orders with various wavelengths at high diffraction efficiency. CONSTITUTION:Light is incident on a liquid crystal grating 1, the light is deflected by the diffraction action, and the light is switched by a light switch and incident on a different wave guide path, a fiber, a light guide path, and a light receiving element. Segments 2 of the liquid crystal partitioned by electrodes are divided into groups (grating lines), the refraction factors of the segments 2 in each group are distributed into the same gradual refraction factor distribution for each group, and the refraction factor distribution is switched from one distribution to another distribution at a high speed. The phase of the light transmitting the segments 2 is changed, the order of the diffracted light is changed to switch the diffraction direction at high efficiency, or the number of the segments 2 in each group is changed, the space frequency is changed to switch the diffracted light angle, and the light path is switched.

Title: Output circuit for digital controller
Inventor: AMANO TAKAYOSHI
IPC: G05B9/02
Filed: 1992-02-06
Abstract: PURPOSE:To output a plant trip signal by setting an output inhibiting element to the conductive state at the time when an output signal off command is inputted from an operation part through an isolator. CONSTITUTION:If a short-circuit fault of an output element 3 occurs, that is, the output of an arithmetic part 8 is turned off, a light emitting element 1a of an isolator 1 extinguishes the light and light receiving elements 1b and 1c are made non-conductive, but the output element 3 is in the conductive state. A current flows to an output inhibiting element 6 through a resistance 5 because the light receiving element 1c is non-conductive, and the current flowing to the short-circuited output element 3 is shunted to the series circuit of a current limiting resistance 7 and the output inhibiting element 6 and an auxiliary relay 4 because the output inhibiting element 6 is in the conductive state. Therefore, the auxiliary relay 4 can be set to the non-exciting state by reducing the current flowing to the auxiliary relay 4 to the holding current of this relay or smaller. Thus, the plant trip signal is outputted.

Title: Phase control circuit
Inventor: SHIMADA SADAHIRO
IPC: H02M1/08
Filed: 1981-02-13
Abstract: PURPOSE:To effectively perform power control by phase control by achieving a charging circuit to a capacitor of a gate trigger circuit by a variable current type constant-current source. CONSTITUTION:A current flowing in a circuit when a power source 1 is in positive half cycle depends upon an FET6 and a variable resistor 7, and the voltage between the gate and the source of the FET6 becomes a current flowing through a circuit of VGS=-R7.I0.R7, resistance of variable resistor 7 and I0. Accordingly, when the voltage applied to the circuit becomes high, the voltage VGS becomes high at the negative side, thereby acting to reduce the current. According- ly, the current I0 does not vary. Similarly, when the power source 1 is in negative half cycle, the current I0 does not change. As a consequence, the current which charges the capacitor 5 becomes constant, the conduction angle theta does not alter, thereby reducing the variation in the power due to the variation in the voltage.

Abstract: PROBLEM TO BE SOLVED: To make the discharge amount in a minute amount, as well as to secure the strength of a plunger, by making the sliding part of the plunger into a two stage plunger having a large diameter part and a small diameter part coaxial each other. SOLUTION: A plunger 1 has the sliding part made in a two stage plunger having a large diameter part 1a and a small diameter part 1b coaxial each other, and it is slided up and down inside a plunger barrel 2. Between the outer periphery of the small diameter part 1b of the plunger 1, and the plunger barrel 2, a pump chamber 2c is formed, and it is communicated to an oil feeding joint metal 9 attached to a pump housing 3, and the oil feeding port 2a of the plunger barrel 2. As a result, the actual cross section area of the pump chamber 2c to compress and discharge the oil can be reduced, without making the plunger diameter smaller extensively. Consequently, a plunger pump necessary to obtain a very minute discharge amount can be provided, as well as the strength of the plunger can be secured.
