摘要:
A valve operating mechanism for operating at least one valve of an internal combustion engine, includes a camshaft rotatable in synchronism with rotation of the internal combustion engine and having a pair of low- and high-speed cams of different cam profiles, a rocker shaft, and a pair of first and second rocker arms rotatably mounted on the rocker shaft and operable selectively by the low- and high-speed cams for operating the valve according to the cam profiles of the cams. A selective coupling is operatively disposed in and between the first and second rocker arms for interconnecting the first and second rocker arms in high-speed operation of the engine and for disconnecting the first and second rocker arms from each other in low-speed operation of the engine.

An internal combustion engine is equipped with a supercharger which includes an intake port, an intake passage communicated with the intake port and a compressor interposed in the intake passage and compressing the intake air flowing through the intake passage. A unidirectional valve such as a reed valve is disposed inside the intake passage in series with the compressor in order to prevent backflow of the supercharged air inside the intake passage and thus to prevent a drop in the engine output when a throttle valve inside the intake passage is abruptly closed.

An electronic part includes a first electronic member having a wiring side. An anisotropic conductive sheet has a first side and a second side opposite to the first side and is disposed on the first electronic member so that the wiring side contacts the first side. A second electronic member has a third side and a fourth side opposite to the third side and is disposed on the anisotropic conductive sheet so that the second side contacts the third side. The second electronic member is electrically connected to the first electronic member through the anisotropic conductive sheet. An elastic body has a fifth side and a sixth side opposite to the fifth side and is disposed on the second electronic member so that the fourth side contacts the fifth side. A pressing member is disposed on the sixth side of the elastic body.
摘要:
An optical disk is constructed such that a thin film including a reflective layer is formed on a substrate, or on a thermoplastic resin layer on the substrate. A stamper having an asperity pattern corresponding to information signals is directly pressed against the thin film to transfer the asperity pattern on the thin film. Heat-pressing the stamper against the thin film makes it possible to further accurately transfer the asperity of the stamper to the reflective layer with less pressing force in the case where the reflective layer is formed on a thermoplastic resin layer.

Disclosed herein are a sheet-like probe capable of surly preventing positional deviation between electrode structures and electrodes to be inspected by temperature changes in a burn-in test, even when the object of inspection is a wafer having a large area of 8 inches or greater in diameter or a circuit device, the pitch of electrodes to be inspected of which is extremely small, and thus capable of stably retaining a good electrically connected state, and a production process and applications thereof. The sheet-like probe of the present invention comprises a contact film obtained by holding a plurality of electrode structures arranged in accordance with a pattern corresponding to respective electrodes to be connected and having a front-surface electrode part exposed to a front surface and a back-surface electrode part exposed to a back surface by an insulating film composed of a flexible resin, and a frame plate supporting the contact film.
摘要:
When displaying moving images by using liquid crystal panels and others, a problem exists in that tail streaks occur, and image degradation is resultantly caused. To solve this problem, an echo suppression circuit divides a video signal into a pair composed of two successive frames for comparison between these two frames in signal level for the purpose of suppressing an echo phenomenon occurring when a liquid crystal panel displays video signals including moving images. If these two frames are not the same in signal level, the signal is accordingly corrected so as to equalize the signal level of these frames. Based on the video signals and others corrected by the echo suppression circuit, a controller operates the liquid crystal panel with AC drive through a source driver and a gate driver. As such, the drive voltage used to operate the liquid crystal panel with AC drive is adjusted so as to be balanced between positive and negative. In this manner, the tail streaks are prevented when displaying moving images.
