Title: Semiconductor device
Inventor: TOGO YOSHIKIYO
IPC: H01S5/06
Filed: 1995-01-24
Abstract: PURPOSE: To provide a semiconductor device with which such an optical modulator or waveform converter that the chirping occurred due to modulation, which is important for high-speed light transmission, is reduced and its output light strength has excellent linearity to input can be realized. CONSTITUTION: A semiconductor device is constituted of a DFB laser 11 for output carrying nonreflective 15 films at both ends, optical coupler 12, optical isolator 13, and modulated laser 14 for input. The modulated light form the laser 14 having a different wavelength than that of the laser 11 is poured toward the resonator of the laser 11 through the isolator 13 and coupler 12. The output light of the laser 11 is outputted through the coupler 12. Therefore, a light pouring type high-speed optical modulator which has excellent linearity, is less in chirping, and does not consume much electric power as compared with the conventional modulator is obtained. The modulator also has a wavelength converting function.

Abstract: PROBLEM TO BE SOLVED: To obtain a cast plate having uniform and fine cast structure and use the cast plate as an Al alloy plate for foil metal by specifying injection pressure of supplied molten metal at the tip part of a nozzle. SOLUTION: The molten Al alloy composed of 0.2-2.8wt.% Fe, 0.05-0.3wt.% Si and the balance Al with inevitable impurities is cast into the cast plate having <=30mm thickness. This cast plate is cold-rolled and as necessary, is intermediate-annealed and further is final-cold-rolled. In this case, the metallic Al alloy is supplied into the space between movable molds 4, 5 from the horizontal direction or while being tilted upward from the lower side to the horizontal direction or just below side by the casting nozzle 2. Then, the molten metal is supplied at <=0.6kPa injection pressure at the tip part of the nozzle 2. By this method, the cast plate can be used as the Al alloy plate for foil metal.

Title: Flat thermal flow-rate sensor
Inventor: NUNOKAWA ISAO
IPC: F02D35/00
Filed: 1993-01-22
Abstract: PURPOSE:To prevent heat from escaping due to heat conduction to a support member from a flat substrate by a method wherein a conductor interconnection and a groove part are formed on the support-member face of the flat substrate on which a temperature-dependent thin-film resistor has been formed. CONSTITUTION:A temperature-dependent resistor 12 as a platinum film is formed on an alumina flat-sheet substrate 11. Then, parts other than an electrode- extraction terminal 12a are coated with a glass paste or the like, a protective film 13 is formed, and a metal thin film 14 for bonding to a support member 16 is laminated on the terminal 12a by a printing method or the like. Thereby, a thin-film resistor element 10 is manufactured. The element 10 is bonded to a conductor interconnection 15 on the support member 16, and a groove 16a is formed in the support member 16. Since the conductor inter-connection 15 is formed on the support member 16 and the element 10 is bonded directly, heat does not escape from a wire. In addition, since the groove part 16a is formed, a heat-insulating layer 19 by the air is constituted, a face from which heat escapes to the support member 16 is reduced, and its temperature rise is reduced. Thereby, the measuring error of the title sensor is reduced.

Title: Method of controlling injected quantity of fuel for internal-combustion engine
Inventor: OOBA HIDEHIRO
IPC: F02D41/24
Filed: 1984-01-25
Abstract: PURPOSE:To achieve an optimal air-fuel ratio even at the transient run of an engine, by calculating the injected quantity of fuel for the engine in terms of the final pressure in an intake pipe determined from a signal produced by the A/D conversion of the output of a pressure sensor for the intake pipe. CONSTITUTION:The detection output of a sensor for the pressure in the intake pipe of an internal-combustion engine is applied to a low-pass filter for the A/D conversion of the detection output. A compensatory processing is performed on the basis of a formula PMDi=PMDi-1+K.(PMA/D-PMDi-1) wherein PMA/D denotes a signal produced by said A/D conversion. In a step 82, the pressure PMOS in the intake pipe is calculated on the basis of a formula PMOS=2PMA/D -PMDi to produce a signal PMOS, in terms of which the injected quantity of fuel for the engine is determined. This results in providing an optimal air-fuel ratio even at the transient run of the engine.

Date May 26, 1994The invention relates to a method and an apparatus for the hydraulic branching of an open stream having at least one straight main stream of a specific momentum and having one or more branch streams. Deflection from the main stream is brought about using the Coanda Effect. The hydraulically working channel, i.e., the main stream channel has an upstream corner in common with the branch stream channel which corner is rounded in the form of an arc of a circle between the upstream channel and the branch channel and which converges toward the corner and extends opposite that wall of the upstream channel leading toward the corner and forms with the corner an outflow gap, such that the momentum of the main stream flow which emerges, creates the Coanda Effect, thereby deflecting the controlled flow of water into the branch channel.
