A disc cartridge is provided. The disc cartridge in which is housed an optical disc includes a main cartridge body unit, rotatably housing an optical disc, and having an aperture for a head part for exposing a part of the optical disc to outside across the inner and outer rims of the optical disc, and a shutter unit mounted for movement to this main cartridge body unit for opening/closing the aperture for the head part. A recess into which is introduced a portion of a head part of the recording and/or reproducing apparatus is formed in continuation to the aperture for the head part in a surface of the main cartridge body unit on which slides a shutter unit in an area opposite to the area of movement of the shutter unit with the aperture for the head part in-between.

摘要:
A method of production of a semiconductor device such as a plastic pin grid array (PPGA) and a plastic ball grid array (PBGA) having a cavity-fill form. In this method, first, a semiconductor element (3) is placed in a cavity (6) formed in a multiple step-like substrate (2). Under this state, a pellet (7), which is in a solid state at a normal temperature, made of an encapsulating resin composition containing specific components, and has specific characteristics, is placed on the semiconductor element (3). Next, the semiconductor device is heated so that the pellet can melt to fill the cavity (6) with the composition, thereby encapsulating the semiconductor device (3). According to the present invention, a semiconductor device having low stress performance and excellent moisture-proof reliability can be efficiently produced.

Still image recording/playback apparatus comprising an electronic still camera having operating components including an image sensor for sensing an image and producing image signals representative thereof, a recorder for recording image signals derived from the image sensor, playback circuitry for playing back the recorded image signals and a camera controller for controlling at least the recorder and playback circuitry. An electronic player is selectively connectable to the camera and has a signal processor for processing the image signals played back by the playback circuitry to produce viewable picture signals, and a player controller for selectively controlling the operation of the electronic player. When a connection between the camera and player is detected, a predetermined operating mode for both the camera and player is established.

A head pad having a drawing face which draws a flexible disk used for an electronic still camera, for example, by negative pressure and which is made so that the head, which moves along the radial direction of the disk so as to record or reproduce data on the disk, projects out on the drawing face, wherein said depressions are formed in the drawing face around the head and corner portions of the bottom faces of the depressions are further cut away to form undercut portions, thus facilitating generation of a greater negative pressure between the disk and the pad drawing face and enabling greater improvement of the head touch and enabling greater stabilization of the drawing force of the disk by the pad. Also, a process for production of the above head pad wherein one face of a plate material is polished to form the drawing face and then is etched to form depressions around the head and undercut portions at the corner portions of bottom faces of the depressions, whereby it becomes possible to mass produce high precision pads and it becomes possible to greatly reduce the cost of the manufacture of the pads.
