    摘要： A portable electronic device in which microswitches (12) controlled by operation buttons (11) are mounted on one side of a printed circuit board (13), and circuit elements accommodated in BGA packages (14), (15) and (16) are soldered on the other side of the printed circuit board. In the portable electronic device, a shield wall (22) for surrounding the BGA packages (14), (15) and (16) is mounted on the printed circuit board (13), a first protrusion portion (18b) for holding down the shield wall (22) on the printed circuit board (13) is protruded from a case (18) of the portable electronic device (10), and second protrusion portion (18c) for holding down surfaces of the BGA packages (14); (15) and (16) on the printed circuit board (13) is protruded from the case (18) of the portable electronic device (10). With such a construction, the BGA packages are prevented from being peeled off from the printed circuit board (13). Further, even when the push buttons are frequently depressed in playing a game, the soldering parts of the BGA packages mounted on the back side of the operation button can be maintained in good conditions.

    摘要： A pretensioner is provided, which can be partially changed in mechanical strength of in a cylinder, in addition, can be widely used. In the pretensioner, the cylinder is molded by forging, and a positioning portion as a high-strength portion is formed from a partition formed using a excess portion produced during the forging-molding. Therefore, while an outer circumferential shape of the cylinder is not changed, a specification of the positioning portion can be varied, the specification including a formation position of the positioning portion, an extension dimension of the positioning portion from the cylinder, and thickness of the positioning portion along a through direction of the cylinder.

    摘要： The present invention provides a coating material for forming a coating layer that can achieve excellent adhesion to a transparent film. The coating material is prepared so that it contains a thermosetting resin, an inorganic filler, and a mixed solvent containing cyclohexanone. The content of the thermosetting resin is in the range from 5 to 20 wt % with respect to the total amount of the thermosetting resin and the inorganic filler, and the content of the cyclohexanone is in the range from 25 to 35 wt % with respect to the entire mixed solvent. By coating a surface of a transparent film with this coating material and then heat-treating the resultant coating, a coating layer with excellent adhesion can be formed on transparent film. The thus-obtained laminate of the transparent film and the coating layer can be used as an antireflection film.

    摘要： This invention relates to a transmissive liquid crystal display including a light source (BL), a reflective linearly-polarizing layer (Pr1), a birefringent layer (A) having specific optical properties and specific retardation properties, a light source-side absorptive linearly-polarizing layer (P1), a liquid crystal cell (LC), and a viewer-side linearly-polarizing layer (P2) which are arranged in this order. In the transmissive liquid crystal display of the invention, light leakage is suppressed in oblique directions so that black brightness can be reduced. A reduction in contrast in the normal direction can also be suppressed, which is caused by the distribution of light to the normal direction.
