Title: Electrode adhesion evaluating method
Inventor: TSUDA SHIGERU
IPC: H01L21/66
Filed: 1992-06-19
Abstract: PURPOSE:To provide a simple method of surely evaluating the adhesion of an electrode to a semiconductor substrate by a method wherein an impact is given to the rear of a semiconductor substrate through a punch to enable the substrate to break into pieces, and the magnitude of adhesion is judged by the crashed pieces. CONSTITUTION:A specimen piece 1 is formed of a semiconductor substrate where an electrode 2 is fixed, the electrode 2 fixed to the substrate of the specimen piece 1 is soldered 4 to a base 3, and an impact is given to the rear of the semiconductor substrate with a punch 5 to break the specimen piece 1 into pieces. If the electrode 2 is large in adhesion, a cleavage plane appears in the specimen piece 1, and if the electrode 2 is small in adhesion to the substrate, the specimen piece 1 is made to scatter, whereby the adhesion of an electrode to a substrate can be evaluated. By this setup, the adhesion of an electrode can be easily and surely evaluated by taking advantage of a fact that the breakage conditions of a specimen piece depends on the adhesion of an electrode.

Title: Mark edge reproduction circuit of optical disk
Inventor: SHINOHARA MASAHITO
IPC: G11B7/00
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To provide an optical disk device that can surely remove a defective sector by verification, and stabilizes reading by reducing the reproduction capability of the verification as compared with the reading. SOLUTION: Switching circuits 13 and 14 are provided so that a first-order differential signal is allowed to pass through a fixed-magnification-rate amplification circuit 14 with a fixed amplification rate on verification, and reproduction capability is reduced as compared with reading. Therefore, a reproduction signal on verification is less different from that on reading in a sector without any defect and no verification errors occur. On the other hand, the distortion of the signal is large in a sector with defects and the verification error occurs, thus eliminating the sector with defects, and hence stabilizing reading.

Title: Semiconductor laser array device
Inventor: YANO MORICHIKA
IPC: H01S5/40
Filed: 1986-07-08
Abstract: PURPOSE:To make it possible to perform stable oscillations with high output in conformity to a single standard transverse mode by removing a portion of an electric bottleneck layer of a combined area and forming a light-guide layer at the above portion. CONSTITUTION:For example, this device allows a Ga0.6Al0.4As layer 2 and an n-GaAs layers 3 to grow on a p-GaAs layer 1 in conformity to a liquid-phase epitaxial growth process and then permits them to grow a double hetero-structure to form laser oscillation areas 8 and combined areas 9. In such a case, growth conditions are selected so that the n-GaAs layers 3a are eliminated in accordance with a melt-back process. In other words, the n-GaAs layers 3a absorbing light at the combined areas 9 are removed and are substituted by a p-Ga0.5Al0.5As clad layer 4. Thus, a difference in refraction factors between the laser oscillation areas 8 and combined areas 9 becomes so smaller that the combined areas 9 turn into guided wave areas. Then it is possible for 0 deg. phase oscillation to oscillate selectively.

Title: Breakwater
Inventor: TORII KAZUICHI
IPC: E02B3/06
Filed: 1981-10-08
Abstract: PURPOSE:To perform water-breaking work as well as hydraulic power generation by a method in which a pump to be driven by the movement of tidal wave is provided between a block with a waterway and a water-breaking mechanism provided in a rocking manner to the block and water is pumped up to the waterway by the pump. CONSTITUTION:When a water-breaking mechanism D receives transverse wave from the direction of X, a wave riding plate 12 with a float 14 rides on the tidal wave and pushes a water-breaking plate 11. Then, a cylindrical stopper 33 goes into a position 33', a valve 36 is opened, and the sea water is pushed up and discharged through a conduit 38 to a waterway 1. At the same time as transverse wave is bent downwards by the wave riding plate 12 and goes into a cavity 2, the wave-breaking plate 11 also goes into the cavity 2, whereby the water level is doubly raised, the upper edge W of the float 23 goes up to the position W', the valve 24 is closed, the valve 22 is opened, and water is discharged through the conduit 21 to the waterway 1. When the transverse wave disappears, the wave-breaking plate 11 moves to the position 11' and thereby the sea water is smoothly sucked into cylinders 34 and 25.

Filed: 1993-06-30
Abstract: PURPOSE:To obtain high output characteristic with few distortion by varying attenuation quantity with a fixed phase in a prescribed operating range by means of a variable attenuator based on an attenuation control signal from an attenuation control means. CONSTITUTION:An input signal is detected and converted by a diode detector 28, and is inputted to the one side of a differential amplifier 32. While, an output signal from an output coupler 24 is also detected and converted by a diode detector 29, and is inputted to the other side of the differential amplifier 32. The differential amplifier 32 compares the output signals of video amplifiers 30, 31, and outputs constant output when they are equal to each other, and varies only the constant output of the one in accordance with the size of difference between them when they are different from each other. The output is converted and amplified to a control voltage to control the variable attenuator 12 by a current buffer amplifier 33, and is supplied to the variable attenuator 12. Amplitude compensation can be performed by adjusting the attenuation quantity of the variable attenuator 12 so that the output can cope with the difference of the output signals of the video amplifiers 30, 31 by the differential amplifier 32, and varying the attenuation quantity without generating a phase error.

Title: Fuel cell cooler
Inventor: YAMAGUCHI MASANORI
IPC: H01M8/02
Filed: 1989-06-26
Abstract: PURPOSE:To make a temperature distribution in a cell surface homogeneous so as to reduce a stress due to a heat deformation by dividing the header part of the cooler into several pieces along the air flow in the cell surface and allowing cooling medium to flow into each cooler in series. CONSTITUTION:Branch pipes are divided into three groups 5 to 7. Cooling medium is allowed to flow from a header inlet from a first stage cooler into a header 2 through a branch pipe group 5, and then flow into a header 3 through a branch pipe group 6. Thus, the cooling medium finally reaches at a final header outlet E. In this flow, the cooling medium flowing through a part on an air inlet side where heat generation is large, is in low temperature and the cooling medium flowing through a part on an air outlet side where heat generation is small is in high temperature, which makes the temperature in the cell surface homogeneous. Since the number of the branch pipes connecting with one header is reduced compared with the conventional manner and the difference in elongation between respective branch pipes is reduced, it is possible to reduce the distortion of a branch pipe supporting part and prevent the damage of the cooler.
