IPC: F23N5/12
Filed: 1997-10-21
Abstract: PROBLEM TO BE SOLVED: To reduce consumed power of a circuit and decrease the time lag required for flame detection. SOLUTION: When electric power is supplied from a power supply through a chalk coil L to an oscillation circuit, any one between transistors Tr1, Tr2 is first switched on.

Title: Bonding wire
Inventor: SATOU TATSUHARU
IPC: H01L21/60
Filed: 1986-12-26
Abstract: PURPOSE:To obtain a suitable hole even by a bonding device in which a gas supply system is not disposed by using a bonding wire in which reducing gas or inert gas is sealed. CONSTITUTION:Inert gas or reducing gas 2 is sealed in a bonding wire 1 made of good conductive metal. For example, an aluminum wire 1 in which reducing gas, such as H2 or inert gas, such as Ar or their mixture gas is sealed in air bubble 2 state is used. Thus, since sealing gas is injected to the periphery of a ball at the time of forming the ball, and the formation of an oxide film on the ball is suppressed to obtain the ball of suitable shape. Accordingly, a wire bonding device for Au wirings in which a function for supplying reducing gas or inert gas is not provided can use a bonding wire of metal which is easily oxidized with an aluminum wire or a Cu wire.

Title: Josephson ad converting circuit
Inventor: OBARA SHIRO
IPC: H01L39/22
Filed: 1987-12-07
Abstract: PURPOSE:To make the inductance of an injection type quantum interference device (SQUID) so as to reduce malfunctions at the time of operating at high-speed by providing two branches which are formed by respectively connecting in series the SQUID and a bias blocking gate and a reference SQUID and another bias blocking gate and making a bias current to flow by connecting the two branches in parallel. CONSTITUTION:A signal SQUID S1 and reference SQUID S2 are connected in parallel with each other. Injection type DC-SQUIDs are used for the SQUIDs S1 and S2 and magnetic-field coupling type DC-SQUIDs are used for SQUIDs S3 and S4. 1st and 2nd branches have the same constitution and the right and left sides of this circuit are made symmetrical about the central axis. When, for example, an impressing current Ic is changed as time elapses while the IA is in the peak zone, the bias currents IB1 and IB2 of the SQUIDs S1 and S2 first become equal to each other, but gradually increase. As the time elapses, the SQUID S2 reaches a voltage state, since the SQUID S2 reaches the threshold earlier than the SQUID S1. Then the current IB2 is no longer made to flow to the SQUID S2 and induces a magnetic flux in the SQUID S3 when the current IB2 flows to a mutual inductance M3 through a resistance R2 and, as a result, the SQUID S3 reaches a voltage state. Therefore, the inductance of the SQUIDs can be smaller and malfunctions can be reduced at the time of operating at high-speed.

Title: Optical attenuator
Inventor: KADOWAKI MAKOTO
IPC: G02B6/12
Filed: 1986-12-27
Abstract: PURPOSE:To obtain an optical attenuator capable of electrically controlling an attenuation factor by forming an area having a different refractive index on a part of a base showing double refraction when a voltage is impressed to form a waveguide and impressing a voltage in the prescribed direction of the base. CONSTITUTION:The waveguide 3 into which impurity is diffused is formed on the base 1. Independent electrode plates 2x, 2y, 2z are formed on six faces of the base 1. The electrode plates 2x, 2y, 2z can impress voltages respectively in the x, y and z directions of the base 1. When a voltage is impressed to the electrode plates, the refractive indexes of the waveguide 3 and the base 1 are changed. When the refractive index of the waveguide 3 is increased, the attenuation is dropped, and on the other hand the attenuation can be increased by reducing the refractive index of the waveguide 3. Thus, the attenuation of the optical attenuator can be controlled by controlling the voltages of respective electrode plates.

Abstract: PURPOSE:To provide a coordinate input device which can specify a coordinate position by means of only an upper transparent electrode of a liquid crystal display panel without using any transparent tablet exclusive for input of the coordinates nor any exclusive driving circuit. CONSTITUTION:A tablet consists of plural electrodes arranged in the coordinate axial direction against the dot pitches and is set on a dot matrix liquid crystal display panel 1.
