Title: Air-fuel ratio controller
Inventor: NATSUMEDA TAKESHI
IPC: F23N1/02
Filed: 1982-11-09
Abstract: PURPOSE:To provide an air-fuel ratio controller with the aid of which a combustion amount varying burner device is operated at a low air excess rate. CONSTITUTION:A first throttle part 1 and a second throttle part 3 are mounted to a fuel gas path 2 and a path 4 for the air for combustion, respectively, and the downstream sides thereof are joined together to generate a mixture pressure. A pressure Pg between a fuel gas pressure control means 5, mounted to the fuel gas path 2, and the first throttle part 1 and a pressure Pa between means 6 for feeding the air for combustion, mounted to the path 4 for the air for combustion, and the second throttle part 3 are guided to a differential pressure detector 11. When a differential pressure is zero, an output which is as if a pressure on the fuel gas side is higher than a pressure on the air for combustion side, is applied as a primary offset to the differential pressure detector. During operation of a device, through operation of the fuel gas pressure control means 5 or the means 6 for feeding the air for combustion, the differential pressure detector is brought into an approximate zero output, and control is conducted so that Pa-Pg is substantially equal to P0, unevenness in an air excess rate due to the error of a diffential pressure device is reduced, and this enables a reference air excess rate to be set to a lower value.

Title: Die-bonding method of semiconductor element
Inventor: NISHIGUCHI KATSUNORI
IPC: H01L21/52
Filed: 1990-07-25
Abstract: PURPOSE:To fix a semiconductor chip to a carrier by using a preform in which an oxide film does not exist on the surface. CONSTITUTION:A foillike preform 2 composed of a eutectic alloy is placed in a prescribed part on a carrier 1. An oxide film which is formed during the storage exists on the surface of the preform 2. The oxide film which has been formed on the surface is removed in an inert gas atmosphere. After the oxide film on the surface of the preform 2 has been removed in this manner, a semiconductor element 5 is placed on the preform 2 in a vacuum. Then, the preform 2 is heated and melted while the atmosphere is being kept; a eutectic reaction is caused; and the element 5 is fixed to the carrier 1 by using the preform 2 as a bonding material. When this method is used, a die-bonding operation of an MMIC whose thickness is at 100mum or lower can be executed with high reliability although it was difficult by conventional methods.

IPC: B26B19/10
Filed: 1988-08-05
Abstract: PURPOSE: To improve convenience by preventing hair from being engaged through a simple means by protruding an edge shaving blade to the side at a position proximate with a main blade and forming a projection for hair guard protruded from the upper surface of the edge shaving blade between the main blade and the edge shaving blade. CONSTITUTION: When an operating handle part is moved up, a projecting part 27b of a lever 27 is locked to a blade attaching stand 33. When the operating handle part is further moved up, an edge shaving blade case 23 is moved up but since the lever is locked, the edge shaving blade 26 starts turning with a protruding boss 26a of the edge shaving blade 26, which is engaged with a long hole 27a on the lever 27, as a turning axis. Afterwards, when the operating handle part is further moved up, the edge shaving blade 26 is turned into protruding state. In such a state, the edge shaving blade 26 is moved up to the height close to the main blade and since the horizontal protruding amount of the edge shaving blade 26 is sufficient, in the case of edge shaving, there is no danger to erroneously cut hair.

IPC: G01F3/16
Filed: 1981-12-09
Abstract: PURPOSE:To improve the measuring efficiency of the flowmeter, by providing a means for returning a piston to a measurement starting position forcibly, in the flowmeter which detects the flow rate without contact in correspondence with the amount of the displacement of a free piston. CONSTITUTION:Both ends of the glass piston 1 having the free piston 4 in the inside are closed by caps having fluid outlet and inlet ports 8 and 9. A displacement detector 5, which generates a voltage in response to the movement of the piston, is provided in the cap 2. The fluid outlet and inlet ports 8 and 9 are connected to the pipe 11, which is in turn connected to a pipe 10 that is communicated to a fluid source, a surge tank, and the like. The pipes 11 and 10 are connected by a bypass 12 that is in parallel with the cylinder 4, a pump 14, and paths of a four way valve 13. In this constitution, when the fluid enters a chamber 6 of the cylinder 1 through the pipe 10 and the outlet and inlet port 8, the piston 4 is pushed to the right, and the voltage corresponding to the flow rate of the fluid is generated in the detector 5. At the same time, the four way valve 13 is switched to a chain line and the piston 4 is forcibly returned. Therefore the measuring efficiency is improved.

Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To prevent reduction in the modulation degree of an SV signal at the time of passage through a branching unit by splitting a wavelength divided multiple signal beam, modulating drop channel light, corresponding to a monitor signal and adding this light to pass channel light. SOLUTION: A drop channel 18 from an optical branching filter 16 is split into split beams 30 and 32 by a beam splitter 34. The split beam 30 is inputted to an SV signal demodulation circuit 36, detects a monitor signal SV(slow velocity) and is inputted to a drive circuit 40. Further, the split beam 32 is supplied to a station as the drop channel light. Next, an optical modulator 38 is driven through a drive circuit 36 by the SV signal and its modulation degree becomes equal with the SV signal. Further, a modulated add channel beam 22' from the optical modulator 38, and a pass channel beam 20 from the optical branching filter 16 are added by an optical branching filter 24 and sent out to a network 6. Thus, when the wavelength divided multiple signal light passes through the branching unit, the modulation degree of the SV signal is not lowered.

Abstract: PURPOSE:To restrict series resistance and capacitance to small values, increase drain breakdown voltage, and improve RF characteristics, by making the distance between the source and the gate of a GaAsFET smaller than the distance between the source and the drain. CONSTITUTION:After a temporary gate electrode 4 is formed on a GaAs substrate 20 on which an active layer is formed, a silicon oxide film 5 is formed on the side-wall of the gate electrode 4. After an N<+> contact layer 14 is formed for the temporary gate electrode 4 in the self alignment manner, an ohmic electrode composed of a gold-germanium layer 6 and a nickel layer 7 is formed. After the temporary gate electrode 4 is eliminated, a gate electrode 13 and metal turning to the upper layer metal of ohmic electrode are vapor-deposited from oblique direction. Thereby, a gate electrode 13 of off-set structure near from a source electrode 8 and distant from a drain electrode 9 can be obtained. Therefore a GaAsFET having excellent Rf characteristics is obtained, wherein the series resistance and capacitance are small, and the drain breakdown voltage is high.
