Patent number: 7544427Abstract: [Object] Various electric wave absorbers for the GHz band have been developed. However, parameters for obtaining the optimal electric wave absorption characteristic are only the shape and the content of a dielectric material or a conductive material, and the degree of freedom of the parameters has been small. Furthermore, in a recent wireless LAN, electric wave absorbers that can be used for absorbing potentially dangerous electric waves in a plurality of bands, for example, in two frequency bands of 2.45 GHz band and 5.2 GHz band, have also been desired.Type: GrantFiled: December 20, 2004Date of Patent: June 9, 2009Assignee: Incorporated National University Iwate UniversityInventor: Hideo Oka

Patent number: 6804889Abstract: A holder 20 is rotatably connected to a body 10. A scribe tool 30 is attached to one end of the holder 20. A plate spring 16 is fixed to the body 10, and a receiving plate 26 is fixed to the holder 20. A piezo-actuator 40 is interposed between the plate spring 16 and the receiving plate 26. One end of a plate spring 50 having a small spring constant is fixed to the holder 20. The body 10 is provided with an adjustment screw 60. When a lower end part 65 of the adjustment screw 60 is protruded, the lower end part 65 presses the plate spring 50 for flexure, thereby generating a resilient force to the plate spring 50. By this, a rotational force is given to the holder 20 and thus a pressing load directing toward a workpiece is given to the scribe tool 30.Type: GrantFiled: March 18, 2003Date of Patent: October 19, 2004Assignees: Beldex Corporation, THK Co., Ltd.Inventors: Hirokazu Ishikawa, Toshio Hayashi, Fujio Tateda, Jun Sakamoto, Hideo Oka

Patent number: 4692123Abstract: An outboard engine has a power unit, an extension case extending vertically and having its upper end coupled to the power unit, and a propeller mounted on the lower end of the extension case and driven by the power unit. The power unit comprises an internal combustion engine having a vertically extending crank shaft and a cylinder having its axis extending horizontally, and a cover assembly covering the internal combustion engine. The axis of the cylinder is inclined to one side with respect to the axis of the propeller when viewed in plan. The outboard engine can be handled with utmost ease since it can be laid down during storage or shipment without being drained of engine oil.Type: GrantFiled: November 17, 1986Date of Patent: September 8, 1987Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Yukio Tada, Hiroshi Umeno, Yasuhiro Sugimoto, Hideo Oka

Patent number: 4551786Abstract: An unencapsulated solid electrolytic capacitor includes a substantially flat, multi-layer solid state capacitor element having an anode lead-out wire welded to a solderable flat anode terminal plate located in the same plane as that of the principal surface of the capacitor element. The terminal plate includes a pair of protrusions formed on a side of the terminal plate remote from the capacitor element. The lead-out wire has an end portion positioned between, but not extending beyond, the protrusions. A method of manufacturing the capacitor includes forming a capacitor element array by aligning respective capacitor element lead-out wires so that they are substantially parallel and are spaced at a predetermined pitch, forming notches at substantially the same locations in the lead-out wires.Type: GrantFiled: May 31, 1984Date of Patent: November 5, 1985Assignee: NEC CorporationInventor: Hideo Oka

Patent number: 4017334Abstract: Disclosed is a process for treating aluminum wherein the surface is contacted with a solution containing phosphate, a tannin, titanium and fluoride prior to inking or lacquering. The process produces a coating exhibiting adhesion, color and corrosion resistance comparable to that obtained via conventional chromium-based processes without creating the pollution problems of chromium disposal.Type: GrantFiled: December 15, 1975Date of Patent: April 12, 1977Assignee: Oxy Metal Industries CorporationInventors: Yasunobu Matsushima, Hideo Oka, Katsuyoshi Noji, Hiroyoshi Nakagawa
