Title: Movable scroll for hydraulic machine
Inventor: TANAKA HITOSHI
IPC: F04C18/02
Filed: 1987-07-06
Abstract: PURPOSE:To improve each sliding characteristic of an Oldham's ring key and a guide groove by embedding a channel consisting of iron-based material, having the guide groove, in a movable scroll. CONSTITUTION:A movable scroll 3 consists of an aluminum alloy, and it is driven into revolution to a fixed scroll 2 via an Oldham's ring 11. Hereat, a channel 12 consisting of iron-based material, having a guide groove 12a to be released downward, is embedded in a formation part of the guide groove engaging a key 11b of the Oldham's ring 11 with the movable scroll 3 free of slide motion. And, outer sides 12b, 12b of the channel 12 are formed into an inverse taper form to be tilted to the side of the guide groove 12a toward the release side of the guide groove 12a. With this constitution, the channel 12 is surely held in a slip-stop state, while even if the Oldham's ring 11 is made of the aluminum alloy, its sliding characteristic is improved so that seizure or binding will never happen there.

Title: Spark plug
Inventor: SHIBATA KOSHI
IPC: H01T13/32
Filed: 1999-06-16
Abstract: PROBLEM TO BE SOLVED: To provide a spark plug improving its igniting capability to the maximum with respect to lean fuel. SOLUTION: An outer electrode 6 and a plug body 8 are separately formed, and the outer electrode 6 is arranged in a combustion chamber 4 in such a direction as is orthogonal to the direction from an intake valve side to an exhaust valve side in the combustion chamber 4. With this construction, because the outer electrode 6 formed in the combustion chamber 4 is arranged always in the direction not preventing the flow of an air-fuel mixture in the combustion chamber 4 regardless of the mounting angle/position around the axis of the plug body 8, it is possible to improve the igniting capability of the spark plug 1 to the maximum with respect to lean fuel.

Title: Manufacture of laminate-type film capacitor
Inventor: OTANI SHUJI
IPC: H01G4/18
Filed: 1989-06-30
Abstract: PURPOSE:To enhance qualities including a high breakdown strength of a cut face or an insulating characteristic, to improve a production yield and to supply low-cost products by a method wherein an encapsulant is executed on a parent capacitor where metallized plastic films have been piled up and, after that, the capacitor is cut and divided. CONSTITUTION:Aluminum 3 is vapor-deposited on one face of a film 2; zinc 4 is flame-sprayed to extract electrodes; lead wires 7 which extract the electrodes to the outside are formed. A capacitor 8 formed by executing an encapsulant 1 on a parent capacitor 6 by using an epoxy-based thermoset resin is cut and divided by using a rotary raw blade. When the encapsulant is executed on the main-body capacitor, a mechanical strength is enhanced; a strain which is caused near a boundary between an electrode extraction part and a dielectric layer at a laminate cut-face of a unit capacitor is removed; or a vacant space or a difference in level which is caused when the dielectric layer is loosened in a laminate direction is eliminated. It is possible to suppress a creeping discharge of a low voltage by an air breakdown at a vacant space in the laminate cut-face.

IPC: H04N1/04
Filed: 1987-07-07
Abstract: PURPOSE:To obtain a device in which the blurring of a video is reduced and miniaturized and inexpensive compared with the one driven by a bimorph type piezoelectric actuator, by oscillating a light transmissive end plate on one side by driving the bimorph type piezoelectric actuator by a sine wave, oscillating the light transmissive plate on the other side by driving a laminate type piezoelectric actuator by a rectangular wave voltage, and performing image pickup with high resolution by interpolating a dead zone between image elements. CONSTITUTION:The exposure timings t1 and t3 of a solid-state image pickup element 3 are set so as to conform with the crest of the displacement waveform of the light transmissive plate 1a, and the timings t2 and t4 with the valley of the displacement waveform. Also, the t1-t4 are set so as to conform with a period where the visual field scan of the laminate type piezoelectric actuator 4c in a horizontal direction is not changed. The visual field scan is performed in sequence of t1 t2 t3 t4 by the displacement in the horizontal direction of the light transmissive plate 1b and the displacement is a vertical direction of the light transmissive plate 1a. In such a case, it is possible to interpolate a part where no pnotodetecting part is prepared actually in the solid-state image pickup element 3 in the timings t2, t3, and t4. Therefore, it is possible to obtain a sharp video since no blurring of the video are generated in both directions, and to constitute a miniaturized and inexpensive device.
