Title: Oxide thin film having rock crystal-type crystal structure and its production
Inventor: TANAKA MOTOYUKI
IPC: C30B1/02
Filed: 1995-07-13
Abstract: PURPOSE: To produce an oxide thin film having a rock crystal-type crystal structure of an arbitrary film thickness and shape in a simple method without using such a large scale apparatus as for a hydrothermal crystallization method and in a low cost. CONSTITUTION: This oxide thin film is composed of at least one layer of 5nm to 50μm in thickness of each layer formed on a substrate. Each layer has a rock crystal-type crystal structure containing silicon dioxide, germanium dioxide or their mixture as a main component. This oxide thin film having rock crystal- type crystal structure is formed on the substrate by a sol-gel method or a vapor- phase accumulation method under an adequate control of substrate temperature optionally by adding a raw material with a very small amount of an alkali metal. A single crystal thin film is obtained by using a single crystal substrate.

Title: Protective device of motor
Inventor: KANEKO RYOJI
IPC: H02K11/00
Filed: 1988-07-15
Abstract: PURPOSE:To facilitate the assembly of a heat sensitive element and to allow a motor to operate accurately by providing the heat sensitive element a brush. CONSTITUTION:A heat sensitive element insertion section 20 is integrally formed with a brush holder 13 to the flank of a brush box 15. The heat sensitive element 21 is inserted into the heat sensitive element insertion section 20 so that its one end may come into contact with the brush box 15, where the heat sensitive element 21 is pressure-welded with spring-loaded pressed segment 22. The pressed segment 22 is integrally formed to the brush holder 13, whose tip section 22a is engaged with a recessed section 21a of the heat sensitive element to stop disjunction of the heat sensitive element 21. In this way, the assembly of the heat sensitive element becomes facilitated as compared with those provided to a coil, etc. Moreover, since the overload of a motor can directly be detected by the heat of the brush and no outside air temperature gives affection, the motor can surely be operated.

Title: Resistive terminator
Inventor: TAKAMIZAWA HIDEO
IPC: C04B35/34
Filed: 1981-11-05
Abstract: PURPOSE:To obtain a resistive terminator having a great reflection loss and excellent heat resistance, by using a sintered body adding bismuth oxide to cobalt. zinc ferrite. CONSTITUTION:Cobalt.zinc ferrite consisting of cobalt oxide, oxide iron oxide and zinc generally has a great magnetic loss, but many holes and is subject to water absorption and in using the material as a resistive terminator, the characteristics have a large dispersion depending on the adsorbed water content. In adding a little of bismuth oxide to this ferrite, however, the ferrite can very deusely be sintered, allowing to offer a high heat resistance and reflection loss to a resistive terminator using this ferrite. The characteristics of examples of execution of this invention are listed in table.

Title: Fuel injection controller for internal-combustion engine
Inventor: TAKEDA YUJI
IPC: F02D41/00
Filed: 1984-08-28
Abstract: PURPOSE:To prevent a spark plug from smoldering as well as to keep off an output drop and a worsening of emission control, by making reduction speed of accelerating increment quick in time of low temperature but slow in time of high temperature, respectively. CONSTITUTION:When an accelerating state of an engine (a) is detected by a detecting device (b), a fuel injection quantity is increased by an increasing device (d) according to engine temperature (c) at that time, and in this case, it is increased much in time of low temperature but less in time of high temperature. At the time of reducing an accelerating increment value by a reduction device (e), this reduction speed is controlled according to the engine temperature (c). That is to say, in time of low temperature, it is reduced quickly but in time of high temperature slowly. With this constitution, smoldering in a spark plug due to excess fuel injection is preventable from occurring and, what is more, a tendency of making an air-fuel ratio, in time of acceleration, into being lean is also preventable.

Title: Production of precipitation hardening type stainless steel washer
Inventor: NAKAMURA MINORU
IPC: C21D9/00
Filed: 1995-06-22
Abstract: PURPOSE: To obtain a washer with which oxidized films are less formed and surface finishing is simple by cutting a round bar of a precipitation hardening type stainless steel to form a disk-shaped working piece, forming the disk-shaped working piece to a washer shape by cold and hot forging and subjecting the washer to a precipitation hardening heat treatment. CONSTITUTION: The round bar of the precipitation hardening type stainless steel is cut to form the disk-shaped working piece of the prescribed size. The piece is formed into the washer shape by the cold and hot forging and is subjected to the precipitation hardening heat treatment. Since the precipitation hardening heat treatment is executed at the temp. similar to the temp. of cold forging, there is no need for heating the working piece to a high temp. as in hot forging and since the oxidized films on the surface is thin, the surface treatment by such a simple method as shot blasting is made possible. There is no end for intermediate annealing either. The disk-shaped working piece is formed from the round bar, by which the production and heat treatment are simplified and therefore, the cost is low and the yield of the material is good.

Filed: 1981-11-06
Abstract: PURPOSE:To attain simple adjustment, by obtaining a voltage having a level in response to a local oscillating frequency from a frequency-voltage conversion circuit, and driving a display according to this volage level. CONSTITUTION:An output signal of a prescler 2 is proportional to an output frequency of a voltage controlled oscillator VCO1, and this signal is inputted to a wave shaping circuit 12. The circuit 12, a monostable multivibrator 13 and an integration circuit 14 constitute a frequency-voltage F-V conversion circuit and the output of the circuit 14 is inputted to a display drive circuit 16 via a DC amplifier 15.

Title: Winding for oil-immersed transformer
Inventor: FURUKAWA SADAO
IPC: H01F27/32
Filed: 1997-07-03
Abstract: PROBLEM TO BE SOLVED: To shorten the main insulating distance of a winding for oil-immersed transformer and improve the mechanical strength of the winding. SOLUTION: A linear spacer 8 is formed by alternately putting tapered insulating pieces 10, 11, and 12 upon another, in such a way that the piece 11 is inserted between the pieces 10 and 12 and firmly binding the pieces 10, 11, and 12 with an insulator 13 which shrinks, when the insulator 13 is heated or dried. When the spacer 8 is heated in a drying process, the insulator 13 shrinks and the thickness of the spacer 8 is increased, because the piece 11 is inserted more deeply between the pieces 10 and 12 by the shrinkage force of the insulator 13. Therefore, the occurrence of a gap between a high-voltage winding 2 or an insulating pipe 7 and the linear space 8 can be prevented, even if the insulating coating of the pipe 7 or winding 2 shrinks as the coating is dried.

Filed: 1998-06-25
Abstract: PROBLEM TO BE SOLVED: To shorten a total cross section monitoring time by reducing a processing time of a sample when the cross section of the sample is monitored by a focused ion beam. SOLUTION: After a sample 5 is fixed to a sample holding plate 10 under a condition that a stress is generated in an inner part, the sample 5 is cut.

Abstract: PROBLEM TO BE SOLVED: To simply improve surface morphology of a semiconductor layer formed on a sapphire substrate by forming a semiconductor layer on the sapphire substrate whose rear surface is polished in mirror plane so as to carry out epitaxial growth by using an organometallic chemical vapor phase growing method. SOLUTION: A crystal is subjected to epitaxial growth on a sapphire substrate whose rear surface is polished to a mirror plane having preferably <=100 nm unevenness by using an organometallic chemical vapor phase growing methods to form a semiconductor layer. In the sapphire substrate, the rear surface is uniformly brought into contact with a susceptor. Thereby, thermal conduction is uniformly carried out in a substrate face and occurrence of unevenness of temperature distribution is prevented and the semiconductor layer is uniformly grown in the substrate face to provide a crystal substrate phase in which surface morphology is improved. A nitride semiconductor represented by the general formula InxAlyGa1-x-yN (0<=x<=1 and 0<=y<=1) is preferable as the semiconductor layer.  A high quality semiconductor layer can be further formed on the semiconductor layer according to maskless ELO(Epitaxial Lateral Overgrowth) technique or ELO technique using mask having opening.
