Title: Method for forming electrode of semiconductor element
Inventor: MATSUSHITA NORIYUKI
IPC: H01L23/52
Filed: 1994-08-01
Abstract: PURPOSE:To make an ohmic connection of an electrode comprising Cr/Au to a GaAs layer without generating the dispersion of element characteristics. CONSTITUTION:An electrode is formed of a Cr layer 11 and an Au layer 12 on a GaAs layer 8 of a semiconductor laser element and heat-treating them to make an ohmic contact.

Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To minimize reduction in a transmission range due to a cable loss in the case of long distance transmission by improving degradation in a noise figure in the reception. SOLUTION: An output signal from a LAN transmitter-receiver 2 is fed to a directive antenna 1 via a circulator 11, a directional coupler 12 and a circulator 13 of the radio LAN booster 10. Furthermore, the signal is detected by a detector 15, amplified by a DC amplifier 16, the amplified signal is given to a control terminal (c) of a high frequency changeover switch 14 to select an output terminal (b) of the high frequency changeover switch 14 and to disconnect a reception path. When the LAN transmitter-receiver 2 is set to the reception mode, no output signal is present from the detector 15 and a control terminal (c) of the high frequency changeover switch 14 becomes an 'L' level.  Thus, an output terminal (a) is selected by the high frequency changeover switch 14, after the received signal is amplified by a low noise amplifier 18 and the amplified signal is fed to the LAN transmitter-receiver 2 from the circulator 11.

Therefore, the reduction of the brake hydraulic pressure and the pumping-up to an accumulator 12 are carried out, and then a gate valve 1 closes a main passage 4. When the wheel deceleration speed lowers a certain value, outputting a signal S2 is suspended, and the brake hydraulic pressure is maintained in the held state. When the wheel speed reaches the acceleration speed state, outputting a signal S1 is suspended, and the pressurized oil supplied from the accumulator 12 is transmitted to a wheel cylinder W/C by opening the hold valve 2.

Filed: 1986-07-30
Abstract: PURPOSE:To prevent edge cracks, surface cracks, etc., from occurring at the time of hot rolling, by minimizing respective contents of Pb and Bi as impurities in phosphor bronze and also by applying hot rolling under specific conditions. CONSTITUTION:The quantities of Pb and Bi as impurities in phosphor bronze containing <7%, by weight Sn are limited to <0.002% and <0.001%, respectively, and, at the time of hot rolling, this phosphor bronze is previously heated to 650-750 deg.C for 0.5-8hr. This stock is hot-rolled at an initial rolling temp. of 650-750 deg.C, and a draft per pass is regulated to <=10%, particularly 3-5%, until the total draft exceeds 20%. Next, there is no necessity for carrying out rolling by the use of edger mills at every pass of rolling until, at least, the total draft of edge-rollings comes to 25%, and, when at least >=25% total draft is reached, edge-rolling is carried out each time. In this way, the hot-rolled plate of phosphor bronze free from edge cracks and surface cracks can be obtained.

Abstract: PURPOSE:To form a copper wiring with high yield, by eliminating photo resist residue on a substratum copper foil with mixed gas plasma wherein CF4 is added to O2, and preventing the eluation of a solder-plated film as the etching resist in an etching process. CONSTITUTION:Photo resist 3 is stuck on the whole surface of a substratum copper foil 2 of a substrate 1. After a patterned copper-plated layer 4 is formed, a solder-plated film 5 whose Sn ratio is 40% or lower is formed on the layer 4, and the plotoresist 3 is peeled. Resist residue 6 left on the substratum copper foil 2 by the solder-plated film 5 process is eliminated by ashing with mixed gas plasma wherein CF4 is added to O2. The solder-plated film 5, whose Sn ratio is 40% or lower, formed on the patterned copper-plated layer 4 is not eluted by a hot water washing treatment before etching process for eliminating the substratum foil in the next process. Thereby the copper residue defect in the etching process can be prevented, and a copper wiring can be formed with high yield.

Filed: 1990-07-09
Abstract: PURPOSE:To reduce noises in specific frequencies of a compressor by providing a converter with a controller to stop the output of power source with the same frequency of vibration as that of refrigerant pipe connecting the converter to the compressor. CONSTITUTION:A converter 6 of outdoor heat exchanging unit 1 is provided with a room temperature setting device 31, a temperature difference detector 32 to detect the temperature difference between the temperature set by the room temperature setting device 31 and the temperature detected by a room temperature detector 24, a computing device 33 to compute the target value of frequency of power source in the range of 35Hz - 105Hz according to the temperature difference, and a control device 40 to switch the frequency of power source to another frequency when the frequency of power source set by device 33 accords almost with the natural frequency of vibration. Because the power source with the same frequency as a natural frequency of refrigerant pipe connected to the compressor is not supplied to the compressor, the transmis sion rate of the vibration to the fixed base of the compressor is suppressed to a low level. In this way, the abnormal vibration caused by base beat, etc. can be prevented and the noise can be reduced.
