Abstract: PURPOSE:To enable favorable ohmic contact to be taken even in a compound semiconductor substrate such as an n-type GaAs substrate, etc., by stacking an AuGe layer, an Ni layer, an AuSn layer, and an Au layer in order on the rear of the substrate using a group III-V compound semiconductor material. CONSTITUTION:An AuGe layer 22, an Ni layer 23, an AuSn layer 24, and an Au layer 25 are formed in order on the rear of GaAs substrate 21. These are processed into a chip 26 by dicing or cleavage in the condition that each metallic layer is made on the rear of the substrate 21. This package 26 is pressure- bonded by heat to a package 27. Favorable ohmic contact is made with the n-type GaAs substrate 21 by the AuGe layer 22 and the Ni layer 23. There is no exfoliation by the superiority of the close adhesion between the Ni layer 23 and the AuSn layer 24, and the AuSn layer 24 itself executes the role of a package 27, so a pellet becomes needless. Furthermore, since the Au layer 25 prevents the oxidation of the AuSn layer 24, the close adhesion to the package 27 improves.

Abstract: PROBLEM TO BE SOLVED: To smoothly guide an optical coated fiber without any excessive bending and surely drop it at a high speed by providing a plurality of rotary wire distribution boards between an assembly die and a fixed wire distribution board. SOLUTION: A plurality of rotary wire distribution boards 61, 62 are provided between a fixed wire distribution board 5 and an assembly die 4. After passing through a wire distribution hole 51 of the fixed wire distribution board 5, respective optical coated fibers 3 are guided to the assembly die 4 via respective wire distribution holes of the rotary wire distribution boards 61, 62. The optical coated fiber 3 thus advances to a bent line ABCD shown by a solid line. These points B, C follow an SZ groove 2 and rotate in the direction following thereto, namely, in the direction for approaching to a point P so that the bending angles in the bent points B, C of respective bent lines become smaller.  That is to say, the advancing route of the optical coated fiber 3 is changed into a curved line more natural as a whole than the bent lines by the rotary wire distribution boards 61, 62 and the increase in the number of the rotary wire distribution boards makes it into a more smooth curve.

Abstract: PURPOSE:To provide titled machine which welds even metal with high thermal conductivity stably by detecting the surface temperature of objects to be welded, and controlling a main power source device on the basis of the detection signal and a reference signal from a surface temperature standard setter for the objects. CONSTITUTION:A differential amplifier 20 compares the reference signal from the surface temperature standard setter 22 for the base materials 10a and 10b with the detection signal, which is proportional to the surface temperature of the base materials 10a and 10b, obtained by processing the detecting output of a temperature detector 16 by amplification 18. On the basis of the difference signal, the main power source device 24 is controlled. Namely, the control over the device 24 is so performed by the output signal of the amplifier 20 that a welding current is increased when the detection signal based upon the surface temperature of the base materials 10a and 10b is lower than said reference signal, on the contrary, decreased when higher. Under this control, the surface temperatures of the base material 10a and 10b are held constant to stabilize the fused state of a weld zone.

Title: Heating and cooling apparatus
Inventor: KAKUBARI ZENICHI
IPC: F25B1/00
Filed: 1990-02-15
Abstract: PURPOSE:To realize smooth circulation of a refrigerant in a cooling operation by connecting a heater between the high pressure passage of the refrigerant, namely, a condenser and a pressure reducing capillary tube. CONSTITUTION:A four-way changeover valve 2 is changed over and a solenoid valve 10 is closed in a cooling operation. Therefore, a refrigerant gas discharged from a refrigerant compressor 1 flows into a condenser 3 via a passage 11, the four-way changeover valve 2 and a passage 12 to become a refrigerant liquid. The refrigerant liquid flows into a heater 9 via a passage 13, a first check valve 4 and a passage 14 and further flows into an indoor heat exchanger 6 via pressure reducing capillary tubes 5a and 5. After cooling the indoor air by the evaporation of the refrigerant liquid in the indoor heat exchanger 6, the refrigerant liquid is sucked into the refrigerant compressor 1 via a passage 15, the four-way changeover valve 2, a passage 16, a check valve 7 and passages 17 and 18. Thus, the accumulation of the excessive refrigerant in the condenser 3 dissolves and the smooth circulation of the refrigerant can be obtained in the cooling operation even with the small size condenser 3.

Title: Gate circuit
Inventor: TANAKA KOUICHI
IPC: H03K17/14
Filed: 1983-03-03
Abstract: PURPOSE:To prevent noise level deterioration due to a temperature rise by inserting a constant voltage element at the base of a gate transistor (TR). CONSTITUTION:The parallel connection body of diodes D1 and D2 is connected to the base of the gate TRQ1; the diode D1 is in the forward direction and the diode D2 is in the backward direction. The diode D2 uses, for example, an aluminum Schottky diode and its forward voltage is smaller than that of the TRQ1. The collector of a control TRQ2 is connected to the common connection point of the D1 and D2 on the side opposite to the base of the TRQ1. When the TRQ1 is off, an inequality I holds where VFD is the forward voltage of the diodes. In this case, the left side member of the inequality I never becomes smaller than the right side member even at high temperature, so the noise level at high temperature does not increase. The diode D2 discharges base accumulated charges of the Q1 when the Q1 turns off and an inequality II holds.
