Title: Vacuum heat insulation material and refrigerator
Inventor: FUJINAMI TAKUMI
IPC: F25D23/06
Filed: 1995-05-26
Abstract: PURPOSE: To increase strength and restrict an increase of heat conductivity due to secular deterioration and hence ensure a heat insulation state stable over a long period of time by forming a core material inserted into an airtight container with urethane foam subjected to a high temperature high humidity processing. CONSTITUTION: In a vacuum heat insulation material wherein a core material is inserted into an airtight container and the inside of the container is reduced in its pressure and the container is sealed, the core material is formed with urethane foam subjected to a high temperature high humidity processing. Urethane foam used as the core material is desirably hard open cell urethane foam. With the high temperature high humidity processing, a non-reaction isocyanate group remaining in the hard open cell urethane foam is inactivated and hence it does not produce carbon dioxide gas even it reacts with water. Hereby, strength is increased, and increased heat conductivity due to secular deterioration is restricted, and hence a heat insulation state stable over a long period of time is ensured.

Title: Formation of alloy layer
Inventor: AOYAMA TOSHISADA
IPC: C23C10/30
Filed: 1995-05-26
Abstract: PURPOSE: To easily form a zinc coating layer by mixing specific amounts of zinc powder of specific grain size with a solution of organic high polymer compound dissipating by thermal decomposition, applying the resulting mixed solution to an iron bar, and then heating the bar up to a temp. not lower then the melting point of zinc. CONSTITUTION: A zinc powder of <=10μm average grain size is mixed by 60-80wt.% with a solution or colloidal dispersed solution of organic high polymer compound. The resulting mixed solution is applied to the surface of a bar composed of iron and iron alloy. The bar is heated to a temp. not lower than the melting point of zinc powder to make the zinc diffuse and penetrate into the surface of the bar. When the average grain size of the zinc powder exceeds 10μm, sedimentation is liable to occur in the case where the zinc powder is mixed with resin solution and, further, the thickness of an alloy layer becomes nonuniform. When the amount of the zinc powder to be mixed esceeds 80%, the amount of resin becomes too small and the ability of sticking film becomes insufficient.  By this method, the coating layer of zinc and alloy layer can be formed while obviating the necessity of equipment for exclusive use for plating, vapor deposition, thermal spraying, etc.

Abstract: PURPOSE:To obtain a compound semiconductor integrated circuit having a high electrostatic surge withstand voltage, by defining the length of the resistance region of a resistor element directly connected with an input terminal or an output terminal. CONSTITUTION:As to resistor elements R1-R4, R7 directly connected with I/O terminals 2-6, either of the length L or the width W is not set to be minimum, but the length L of a resistor region is defined independently of a resistance value R, and then the width W is determined according to the resistance value R. The length L of the resistance region is set to be longer than or equal to 25mum. That is, when the length L of the resistance region is shorter than or equal to 25mum. the electrostatic surge withstand voltage becomes small and lower than or equal to 30 V, but when the length L is longer than or equal to 25mum, the large electrostatic surge withstand voltage higher than or equal to 150 V can be obtained. Thereby electrostatic breakdown withstand voltages of the resistor elements R1-R4, R7 become larger than the breakdown voltages of protective diodes D2-D6, which can effectively be operated.

Title: Thin film transistor and manufacture thereof
Inventor: MATSUMOTO HIROSHI
IPC: H01L29/78
Filed: 1990-05-21
Abstract: PURPOSE:To make a thin film transistor small enough in hysteresis of VG-ID characteristics so as to enable it to carry out an excellent switching action by a method wherein a very small amount of N-type impurities is diffused into a semiconductor layer. CONSTITUTION:A very small amount of N-type impurities is diffused into a semiconductor layer 14. If N-type impurities are diffused into the I-type semiconductor layer 14, the semiconductor layer 14 is lessened in band gap, so that a band gap difference between the semiconductor layer and a gate insulating film 13 becomes large. Therefore, the injection of charges between the semiconductor layer 14 and the gate insulating film 13 is of no effect, and in result a thin film transistor of this design becomes small in hysteresis. By this setup, a thin film transistor is possessed of a VG-ID characteristic very small in hysteresis.
