Title: Noise removal method of electronic apparatus
Inventor: YAMASHITA TOMOFUMI
IPC: H05K9/00
Filed: 1994-03-24
Abstract: PURPOSE:To reduce the noise of an electronic apparatus by means of the small number of components as compared with conventional techniques by a method wherein a solid electrolytic capacitor which uses an organic semiconductor as an electrolyte is connected between a power-supply line and a grounding line for an electronic circuit. CONSTITUTION:A solid electrolytic capacitor is formed in such a way that a capacitor element in which an anode foil and a cathode foil, on both of which oxide films have been formed and which are made of aluminum, are wound together with a separator, that the capacitor element is impregnated with a molten TCNQ complex salt as an electrolyte and that the complex salt is cooled and solidified. The solid electrolytic capacitor is designated simply as an 'OS capacitor'. When the OS capacitor is connected to a power-supply line in parts encircled and specified in an on-screen display circuit for a VTR, a noise level can be lowered as compared with a case where an LC filter is connected to the power-supply line. That is to say, since the LC filter or an RC filter which is used in conventional cases in order to remove the noise of a power-supply line in various kinds of electronic circuits is replaced by one solid electrolytic capacitor which uses an organic semiconductor as an electrolyte, the number of components can be reduced.

Title: Intake device for engine
Inventor: TANAKA TOSHIMASU
IPC: F02B29/08
Filed: 1984-03-21
Abstract: PURPOSE:To achieve good combustion performance under wide load area by providing an auxiliary intake path branched from the intake path in the upstream of a gate valve and communicated to one intake port while delaying the opening timing of intake valve of one intake port. CONSTITUTION:Under low load area where a gate valve 18 will close, all of the intake air passing through main intake path 11 is led through an opening 19 to an auxiliary intake path 20 while fed through an opening 21 into a combustion chamber 4. Since the cross section of said path 20 is set lower than those of respective branch intake path 15, 16, relatively high flow speed can be achieved even under low load where the intake air flow is low. While second intake valve for opening/closing second intake port 6 is set to open slightly earlier than first intake valve for opening/closing first intake port 5. Consequently, variation of the strength of swirl of intake air due to the variation of load can be suppressed to achieve good combustion performance.

Abstract: PURPOSE:To automate separation of a product from a plate, to shorten a separation time, and to prevent the generation of burrs by exerting an impact on the plate by means of a coil to generate an impact from the one surface when coupled products are separated from each other. CONSTITUTION:A plate W wherein products G are intercoupled through a small coupling part J is placed on work support members 25 and 27 for an X-axis and a Y-axis of a body frame 15. By moving the support members 25 and 27 in an X-axis and a Y-axis, respectively, the plate material W is set to an origin position. An impact frame 21 is then moved to the positions of separating products (G1 and G2). When, by respectively rotating the members 25 and 27 in a 180 deg. arc, resilient members 29 are brought into an up state from a down state, the upper surface of the plate W is adhered to a coil 3 or a passive plate 11. When, with this state, the coil 3 is energized, an impact is generated on the coil 3, and the products G can be automatically and easily separated from the plate W. In which case, when the plate 11 is located between the coil 3 and the plate W, by exerting an impact on the plate 11, the impact is propagated to the plate W to separate the products G.

Abstract: PROBLEM TO BE SOLVED: To reduce high order fluctuation pressure by forming a film-like thing composed of bubbles in an upper part of a propelling propeller. SOLUTION: A ship 1 has an air blowout device 5. An air blowout port 12 of an air blowout nozzle 10 constituting this air blowout device 5 is positioned in front of a propeller central position 15, and is positioned between a horizontal plane passing through the uppermost end of a propeller rotating surface and a hull outside plate 9, and is positioned on the starboard side more than the hull center.
