摘要： A single-chip microcomputer comprising: a first bus having a central processing unit and a cache memory connected therewith; a second bus having a dynamic memory access control circuit and an external bus interface connected therewith; a break controller for connecting the first bus and the second bus selectively; a third bus having a peripheral module connected therewith and having a lower-speed bus cycle than the bus cycles of the first and second buses; and a bus state controller for effecting a data transfer and a synchronization between the second bus and the third bus. The single-chip microcomputer has the three divided internal buses to reduce the load capacity upon the signal transmission paths so that the signal transmission can be accomplished at a high speed. Moreover, the peripheral module required to have no operation speed is isolated so that the power dissipation can be reduced.

摘要： A lens barrel includes a holder, a lens frame, and an elastic member. The holder includes a first guide axis and a second guide axis. The lens frame includes a first guide section which is movably fitted around the first guide axis and a second guide section which is movably fitted around the second guide axis, and retains at least one lens. The elastic member exerts an energizing force on the second guide section and is disposed between the holder and the second guide section. The lens frame moves along the optical axis direction of the lens as the first guide section is guided by the first guide axis. The elastic member energizes the lens frame along the optical axis direction of the lens by exerting an energizing force on the second guide section. The distance from the holder to the second guide section is different from that from the holder to the first guide section.

摘要： The present invention provides a liquid crystal display device having a large holding capacitance in the inside of a pixel. A liquid crystal display device includes a first substrate, a second substrate arranged to face the first substrate in an opposed manner, and liquid crystal sandwiched between the first substrate and the second substrate. The first substrate includes a video signal line, a pixel electrode, a thin film transistor having a first electrode thereof connected to the video signal line and a second electrode thereof connected to the pixel electrode, a first silicon nitride film formed above the second electrode, an organic insulation film formed above the first silicon nitride film, a capacitance electrode formed above the organic insulation film, and a second silicon nitride film formed above the capacitance electrode and below the pixel electrode. The second silicon nitride film is a film which is formed at a temperature lower than a forming temperature of the first silicon nitride film. The first silicon nitride film and the second silicon nitride film form a contact hole therein by etching both of the first silicon nitride film and the second silicon nitride film collectively by dry etching. The second electrode and the pixel electrode are connected to each other via the contact hole. A potential different from a potential applied to the pixel electrode is applied to the capacitance electrode, and a holding capacitance is formed by the pixel electrode, the second silicon nitride film and the capacitance electrode.
