Title: Manufacture of vertical type semiconductor element
Inventor: MURAKAMI KOUICHI
IPC: H01L23/522
Filed: 1982-04-09
Abstract: PURPOSE:To prevent the generation of element defects due to short-circuit or poor withstand voltage by a method wherein an anodic oxidation is performed between the process of contact hole opening for the electrode of the surface side of a substrate and the process of adhering an electrode substance on this contact hole. CONSTITUTION:When there is short or low withstand voltage between a source and a drain, a current flows from the substrate 1 to a cathode via the source region 3 as shown by the arrow mark, and an insulating anodic oxide film (SiO2) 11 constituted of the fixed thickness d is formed on the surface of the source contact hole 8. Next, Al which is the electrode substance is evaporated on the surface of a substrate, and, when an Al electrode 13 is formed thereby, the source region 3 and the Al electrode 13 are adhered closely each other resulting in ensuring good conduction, in a normal transistor. On the contrary, in a transistor of defects between the source and the drain, the both are electrically insulated by the anodic oxide film (SiO2) 11 formed between the source region 3 and the Al electrode 13, and accordingly the electrode 13 is not short-circuited by the substrate 1 and Al.

Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To provide a small-size motor including an inverter, in which the life a capacitor is elongated. SOLUTION: A cover 29 has a ventilation hole 29b, through which cooling air is passed, and a ventilation path 31 to ventilate the cooling air into a through hole 26a of a capacitor 26. The capacitor 26 is cooled well by the cooling air through the ventilation path 31, so the life of the capacitor 26 is elongated. Since the capacitor 26 is made flat and the length in height is made small, the inside volume of the cover 29 is made small. Then, the whole body of a motor 21 with an inverter is made small.

Title: Hammer device
Inventor: SUZUKI TOMIO
IPC: E02D7/10
Filed: 1983-04-06
Abstract: PURPOSE:To generate a great penetrating force without noise by lowering a weight when the pressure is reduced by a method in which a piston and a cylinder are provided to each of a weight and a pile, and the feeding and discharging of pressure oil and water into the cylinder are intermittently controlled. CONSTITUTION:Pipes 2 and 3 through which pressure oil and water are supplied and discharged are provided to a cylinder 1, and a weight receiver 4 is provided to the upper part of the pipes. A coupler 9 for a pile 8 is provided to the lower part of a piston 7, and the whole of the device is hung down by a wire 10 and a hanger 11. Pressure oil and water are fed via the pipe 2 and discharged from the pipe 3. When the inflow amount of the pressure oil and water is smaller than the outflow amount, the amount of oil and water in the cylinder 1 is abruptly reduced, and thereby the weight 5 goes down with the cylinder 1. Whereupon, a great penetration force is generated at the lowering end portion and the pile 8 is driven. Noise and vibration can thus be leassened, energy-saving effect can be obtained, the structure can be simplified, and the movement of the hammer device can be made easier.

Inventor: ZECHNALL MARTIN DR
IPC: G01F1/692
Filed: 1998-03-11
Abstract: PROBLEM TO BE SOLVED: To ensure a stable temp. dependency of electric resistance by using a platinum layer containing a low quantity of zirconium or zirconium oxide. SOLUTION: A thin film element 4 is patterned to form a resistance loop in a film region by a thin metal layer. With two conduction paths 5, 5 one end of each resistance loop is connected to one connection part 6. To the part 6 a lead wire for the connection of a sensor 1 to an external part can be fixed. By the aid of the element 4 formed as the resistance loop in this way, a current can be supplied and a voltage drop generating at that time can be measured. In the case where the element 4 is formed from a material of which electric resistance is dependent on temp., the temp. of a film 3 can be measured accordingly. It is noted that platinum is especially suitable to form the element 4 which can be produced with a reproducable temp. dependency of electric resistance thereby.  To ensure a long time stabilization of the temp. dependency, after the element 4 made from platinum is produced, it should be subject to heat treatment at a temp. not less than 500 deg.C.

Title: Combustion chamber forming member for internal combustion engine and method of producing the same
Inventor: FUKUDA MASAKATSU
IPC: C23C4/06
Filed: 1978-05-22
Abstract: PURPOSE:To improve the heat insulating and resisting characteristics of a combustion chamber forming material for an internal combsution engine by coating the contact surface side of the material with high temperature gas with contact member formed of nickel or iron porous metal. CONSTITUTION:When the contact surface of a piston is coated, for example, with porous metal 7 of nickel or iron alloy or the like, the pore opening diameter of the metal 7 becomes about 0.1mm. In order to prevent the interior of the piston from being polluted through the pores, ceramic is sprayed only on the surface of the metal 7 to close the pores. Since penetrated layer 9 is formed on the contacting surfaces between a piston mother material 2 and the metal 7 thus formed, the adhering strength of both the material 2 and the metal 7 becomes large. Accordingly, it can thus obtain a piston having superior heat insulating and resisting characteristics strong against crack and separation.

Filed: 1993-03-19
Abstract: PURPOSE:To obtain a high-quality dyed product free from dyeing unevennesses, high in the degree of exhaustion by bringing a dyeing liquor-imparted and dried fibrous material into contact with a parallel-traveling band-like material impregnated with a dye-setting liquor followed by squeezing to impart the fibrous material with a specified weight range of the setting liquor and then by carrying out steaming. CONSTITUTION:In carrying out continuous dyeing (or printing) of a fibrous material comprising natural or regenerated cellulose fibers with a reactive dye, the fibrous material is first imparted with a setting agent-free dyeing liquor (or a printing color size) and dried. Second, an endless parallel-traveling band-like material is impregnated with a setting liquor containing a neutral or alkaline electrolyte (NaOH, Na2CO3, etc., except water-glass) followed by regulating the pickup using a squeezer. Then, the resultant band-like material is brought into contact with the above continuously conveyed dried fibrous material followed by squeezing to impart the fibrous material with 15-60wt.% of the setting liquor and then steaming this material, thus obtaining the objective dyed product free from dye bleedout and dyeing unevennesses. With this method, the degree of exhaustion of the final product can be raised with a small amount of the setting agent, thus being advantageous in terms of environmental protection.
