Abstract: To decrease the area of a chip, improve the manufacturing efficiency and decrease the cost in a semiconductor device such as a driver integrated circuit having a number of output pads, and an electronic circuit device such as electronic clock. There are disposed output pads superposed in two dimensions on driving transistors or logic circuits connected thereto, respectively. Further, not only aluminum interconnection but also bump electrodes or barrier metals are used for the interconnection of the semiconductor device. In a case where a semiconductor integrated circuit is electrically adhered on to a printed circuit board in a face down manner, a solder bump disposed on the semiconductor integrated circuit and the interconnection of the printed circuit board are directly connected to each other, thereby realizing the electrical connection. On this occasion, the bump electrode as the external connecting terminal of the semiconductor integrated circuit is laminated on the transistor.

Abstract: A pickup adjusting mechanism is provided with a turntable on which a disk-shaped recording medium is clamped, a disk motor which drives the turntable, a first base which supports the disk motor, a pickup which reads information recorded on the disk-shaped recording medium, a second base which is supported on the first base and movably supports the pickup, and an angle adjusting part which is provided between the first base and the second base, and adjusts an angle of the pickup with respect to the disk-shaped recording medium clamped on the turntable.

Abstract: A disk ejection mechanism includes a tray on which a recording disk is held, the tray being arranged so that the tray is movable between an inserted position and a disk-change position in both an insert direction and an eject direction. A tray locking member locks the tray when the tray is at the inserted position. A tray pushing member pushes the tray in the eject direction by an actuating force, the tray being ejected by the tray pushing member when the tray is unlocked from the tray locking member. A slidably-arranged eject switch, associated with the tray locking member, unlocks the tray from the tray locking member when the eject switch is moved in a direction perpendicular to both the insert direction and the eject direction.

Abstract: A tray guide mechanism for guiding a movement of a tray in one of an inserting direction to insert the tray into a chassis of a disk apparatus and an ejecting direction to eject the tray from the chassis includes a rail connecting unit provided on a side of the tray, the rail connecting unit being integrally formed with the tray. A slide rail is movably supported on the rail connecting unit. A rail guide unit is fixed onto a side of the chassis and movably supports the slide rail on the rail guide unit. In the tray guide mechanism, the rail connecting unit on the side of the tray comprises a pair of longitudinally extending projections with a groove between the projections, the slide rail being fitted into the groove of the rail connecting unit.

Abstract: A disk information recording medium is loaded on a tray. The tray is loaded in a frame and rotated when information is read from the disk information recording medium. The tray projects from the frame and causes the disk information recording medium to be exposed from the frame when the disk information recording medium is replaced with another one. A braking member is provided on the frame in a position such that the braking member comes into contact with the disk information recording medium when the tray having the disk information recording medium loaded thereon projects from the frame and exposes the disk information recording medium from the frame.

Abstract: A disk drive apparatus which eliminates the eject button on a front bezel and eliminates the opening for the eject button is provided. A tray carries a recording medium, and is movable between an eject position in which the recording medium in the tray is ejected and a disk loading position in which the recording medium is positioned inside the disk drive apparatus for reading operations. The tray is moved toward the eject position by a moving mechanism. The tray is maintained in the disk loading position by an engaging member engaging with the tray. An engagement of the tray is released by pressing the tray in a disk loading direction from the eject position to the disk loading position.

Abstract: The present invention is provided for improving latch-up resistance in a semiconductor integrated circuit device employing CMOS structure, for preventing the photoelectric carriers from getting into the sensors and improving the afterimage characteristic in a semiconductor image sensor device, and for impurity the switching characteristic in a semiconductor device having bipolar element.
