Title: Manufacture of semiconductor device
Inventor: KATO ICHIRO
IPC: H01L21/76
Filed: 1987-10-13
Abstract: PURPOSE:To obtain an element isolating layer having no bird beak by implanting an impurity into an isolating region thereby to form a high impurity concentration layer, forming a low impurity concentration silicon layer covering the boundary region of the vicinity of an element forming region, and oxidizing it. CONSTITUTION:An element forming region and an isolating region are formed on one surface of a substrate 10 made of silicon single crystal containing low concentration impurity. High concentration impurity is implanted into the isolating region, and a high impurity concentration silicon layer 22 which arrives at a predetermined depth from the surface is formed. A low impurity concentration silicon layer 28 selectively covering a whole element forming region and a boundary region near the element forming region of the layer 22 is formed. The surface of the substrate 10 from which the layers 28, 22 are removed is oxidized, thereby forming a silicon oxide film 30 having a predetermined thickness. The substrate 10 is exposed on the element forming region. Thus, an element isolating layer having no bird beak is obtained.

Title: Partial oxidization for hydrocarbon and device therefor
Inventor: ITO DAISHIN
IPC: F02M21/02
Filed: 1991-10-04
Abstract: PURPOSE:To solve problems when employing an ignition by a conventional plug and to stably and surely obtain hydrogen with high yield in accordance with an effective ignition without generating a ignition error in a method for obtaining a gas mainly containing hydrogen in accordance with the partial oxidization of hydrocarbon. CONSTITUTION:A material gas containing hydrocarbon and oxygen is fed to a cylinder 5, compressed by a piston 6 and ignited with a compressed gas to obtain a produced gas mainly containing H2. The compressed gas is irradiated with laser beams through a translucent window 12 from a laser irradiation device 4 and ignited. Accordingly, since the compressed gas is not subjected to the influence of a free carbon, an ignition error can be prevented. Since the laser can give a high ignition energy to a wide range, a hydrogen can be easily and surely obtained with a high yield based on an effective ignition.

Title: Method for controlling direction of combine
Inventor: ONO HIROYOSHI
IPC: A01B69/00
Filed: 1987-10-12
Abstract: PURPOSE:To carry out smooth reaping operation, by detecting the reaping row with a row-reaping sensor and switching the control to a side-reaping with a side-reaping sensor when a specific number of the detection signals of opposite lateral directions are continuously and alternately outputted during the movement of the combine at a definite distance. CONSTITUTION:An interrow spacing of culm relative to the moving direction of a combine is detected by a row-reaping sensor 2 attached to the tip end of a reaping apparatus 1 and judged whether the reaping direction is parallel or perpendicular to the row. When the judged result is parallel, the steering control is carried out based on the detection result of the right and the left culms detected by the row-reaping sensor 2. When a specific number of the detection signals of opposite lateral directions are continuously and alternately outputted from the row-reaping sensor 2 during the movement of the combine at a definite distance and abrupt hunting of the machine body takes place, it is judged that the side direction is erroneously judged as the row direction to interrupt the steering output and switch the control to side-reaping control with a side-reaping sensor 5.

Abstract: PURPOSE:To remove the dislocation between a bearing hole and a conductive pattern and lessen dispersion or slippage, which occur in the relation of contact position between a conductive brush, rotating together with an output shaft, and the conductive pattern, and control the stop angle position of the output shaft by molding the bearing hole on the conductive pattern integrally with a wiring board. CONSTITUTION:A conductor pattern 2 and a bearing hole 25 are manufactured in the range of very small dislocation by molding the conductor pattern 22 and the bearing hole 25 integrally when molding a wiring board 20. As a result, dispersion or slippage occurring in the relation of the contact position between the conductive brush 17, rotating together with the output shaft 25 set in the bearing hole 25, and the conductive pattern 22 becomes very small. Accordingly, the stop angle position of the output shaft 15 can be controlled accurately by controlling the rotation and stoppage of a motor 7 from the contact relation between a collective brush 17 and the conductive pattern 22.

Title: Charger
Inventor: KIBE TETSUICHIROU
IPC: H01M10/46
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To attain cost reduction, improve reliability against additional stress from the outside, and obtain a structure which prevents variation from occurring at contact pressure between mutual terminals by forming a charging terminal out of a metallic plate material stamped by means of press work, and using elastic capability of metallic material. SOLUTION: A charging terminal 1 is formed with only stamping by means of press work using a mold suited to the shape of the charging terminal, therefore, a free shape can be selected. The thickness of the charging terminal 1 is kept constant to stamp a metallic plate material whose thickness is uniform. The characteristic of the charging terminal 1 is influenced by not only the character of the material of the metallic plate itself but also the thickness, width, positions of the contact 2 and rotational fulcrum 3 of the charging terminal and so on. However, by selecting these values appropriately, its shape can be selected over a variety of ranges within the elastic deformation range of the material. It is possible to attain the charging terminal 1 and its mold at a low cost and a highly reliable charging terminal.

IPC: B42D15/08
Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To discriminate the release at a confidential postcard which makes it possible to visually recognize information by the release of a temporarily adhered surface. SOLUTION: One surface of a surface to be temporarily adhered is coated, with a releasable type sticky layer 2 which is not adhered in a normal state before adhering and after releasing and adhered by pressure, and the other surface is formed with an overprint layer. A sheet that inner information can be visually recognized when released is formed with a strong adhered part 6 that a base material and the layer 2 are adhered by stronger adhesive strength than that of the layer 2 to the overprint layer to be formed with a pattern such as reversed character on the part exposed with the base material without overprint layer on the surface to be temporarily adhered with the overprint layer formed.  When it is released after it is temporarily adhered, the surface layer side of the base material of the part 6 exposed before the temporary adherence is broken to be transferred to the layer 2 side together with the layer 2, and hence it is discriminated that the reversed character having the broken surface is released.

Title: Lubricant provided with function of preventing oxidation of high-temperature metal surface
Inventor: HIRAME YASUTERU
IPC: B22D11/111
Filed: 1989-10-03
Abstract: PURPOSE:To obtain a lubricant provided with functions of both lubrication and preventing oxidation of a high-temperature molten metal surface by mixing a vegetable or mineral oil with a tetrafluoroethylene resin so as to disperse the resin in the oil to form a colloid. CONSTITUTION:A lubricant which contains at least one oil selected from a vegetable oil, such as rapeseed oil or soybean oil, and a mineral oil, such as liquid paraffin or mineral oil, and 1-20wt.%, based on total weight, tetrafluoroethylene resin dispersed in the oil to form a colloid. This lubricant can be used for all kinds of processing, e.g. casting of iron, iron alloy, stainless steel, aluminum, aluminum alloy, copper, etc. Particularly in, e.g. casting of iron, a tetrafluoroethylene resin alone cannot perform a lubricating action in some cases. In those cases, boron nitride may be added thereto. Since the use of a lubricant having boron nitride incorporated therein can improve the mold release properties of metal, boron nitride can be employed as a component of a lubricant for processing, such as casting, of all kinds of metals.
