Title: Coated particulate metal material and manufacture thereof
Inventor: POOPATEI KATEIRUGAMANATAN
IPC: C09D11/00
Filed: 1990-06-13
Abstract: PURPOSE: To improve shielding effect for interrupting an incident electromagnetic wave with reflection and/or absorption by coating the powdered or granular metallic materials with intrinsic conductive polymer-formed materials. CONSTITUTION: The powdered or granular or flaky or fibrous metallic materials are peculiarly coated by the conductive polymer-formed materials. The powered or granular metallic materials are desirable to have the aspect ratio of 1-10000 and average diameter or average length of 0.1-500μm, and it is desirable that they have the average diameter or the average length of 10-300μm. Since plural coating layers are desirable to be combined and used for the coating layers, the plural coating layers are combined and coated. But, at least one of the coating layers is coated by the coating layer being intrinsic conductive polymer. Thus, shielding effect for interrupting the incident electromagnetic wave can be improved by reflection and/or absorption.

Title: Gas insulated switchgear
Inventor: SHIRAISHI KATSUHIKO
IPC: H02B13/02
Filed: 1995-06-20
Abstract: PURPOSE: To prevent decrease in insulation of an outlet conductor and a current transformer by locating the current transformer closer to a cutout section than an upper end of a hot gas blow port of the cutout section in a tank of a cutout section. CONSTITUTION: In a tank of a cutout section 16 that is filled with insulation gas, a cutout section 2 which has a hot gas blow port 21 and a current transformer are installed. The current transformer 4 is located closer to the cutout section 2 than it is to an upper end of the hot gas blow port 21 of the cutout section 2. Therefore, even if the hot gas is blown from the hot gas blow port 21, the hot gas does not work on an outlet conductor 3 and the current transformer 4, and thereby the outlet conductor 3 and the current transformer 4 are not affected by the hot gas flow. By this method, the decrease in the insulation of the outlet conductor 3 and the current transformer can be avoided.

Title: Heat transfer pipe
Inventor: SAKAI TOSHIYUKI
IPC: F28F1/02
Filed: 1986-06-30
Abstract: PURPOSE:To improve the pressure resisting performance as well as thermal conductivity by compressing the heat conducting pipe from outside along the lengthwise direction and continuously welding the compressed locations so that the pipe may be divided into multiple flow passages. CONSTITUTION:In order to divide the interior of a flat pipe (a), the pipe is continuously compressed along its lengthwise direction at several lateral points. By applying the resistance welding at mating points A, the interior of the pipe is divided into multiple flow passages 4a, 4b, 4c, 4d. As the heat conducting pipe 4 so processed has the divided flow passages 4a, 4b, 4c, 4d, each of them becomes more or less a round shape, resulting in an improvement in the pressure resisting performance. Regarding the heat transmission performance, the coefficient of overall heat transmission becomes larger as the ratio between the air side surface area and the refrigerant side surface area is made smaller. Therefore, since the present heat conducting pipe 4 has a large pipe interior surface compared to prior flat pipes even though the outside surface area remains same, the coefficient of overall heat transmission becomes larger, improving the thermal conductivity as compared to the prior arts.

Title: Package device and manufacture thereof
Inventor: SUGIHARA HISASHI
IPC: H05K3/34
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To prevent a chip from being stressed due to the thermal expansion of a sealant by forming irreguralities on the surface of a package. SOLUTION: The package device 1 has a package 3 and chip 2 sealed therein. The package 3 is like a rectangular thin plate with chip's leads 4 extruding from its four side faces and has irregularities on the surface to form grooves 7 arranged with specified spacings on the top face of the package. Soldering causes the package to thermally expand, resulting in a stress concentrated on the irregularities and hence in the absorption of the thermal stress. Thus, a high stress is never exerted on the chip, this preventing the life reduction, function deterioration and function breakdown of electronic circuits in the package. The irregularities formed as grooves reduce the stress being exerted on the chip, keeping a bending strength of the package in a fixed direction.

Title: Print head
Inventor: AOKI KENICHI
IPC: B41J2/275
Filed: 1989-06-16
Abstract: PURPOSE:To obtain a print head with an excellent high-speed follow-up property and make the print hammering force stronger by a method wherein a double structure is given to the return spring of an armature so that the returning force, which is added to the armature, suddenly increases when approaching a core stud end surface, and the return motion of the armature can be smoothly performed, when an armature gives a print hammering motion. CONSTITUTION:At the rising time of an print hammering motion of an armature 2, a conventional return spring 8 works alone. Only when the armature 2 approaches the end surface of a core stud 3, and the armature 2 transfers to a return motion, auxiliary return spring 8A works, and in addition to the force by the conventional return spring 8, the force by the auxiliary return spring 8A is added, therefore, the returning force, which is impressed to the armature 2, increases. By this method, without spoiling the motion rising property and print hammering force of the armature 2, the returning motion is smoothly performed while resisting the drawing force by remaining magnetic flux in the magnetic circuit and the inertial force, etc., of the armature 2 and a print wire 1.
