The back side of a strip substrate with plural semiconductor chips mounted thereon is vacuum-chucked to a lower mold half of a mold, and in this state the plural semiconductor chips are sealed with resin simultaneously to form a seal member. Thereafter, the strip substrate and the seal member are released from the mold and are cut into plural semiconductor devices. The semiconductor devices thus obtained are improved in their mounting reliability.

Liquid crystal for a right eye and liquid crystal for a left eye are not positioned in one plane, but are positioned to incline at an angle of 5°. To be concrete, both liquid crystal are inclined so that they become closer to the viewer's face as making toward the side of the face from the middle of the forehead. The inclination of liquid crystal as above-described to set the preferential direction of visual view of liquid crystal to be horizontal leads in that the direction by which the high contrast of liquid crystal can be obtained is toward the 3D display. It diminishes a phenomenon like cross-talk and allows the viewer to view the appropriate stereoscopic image. Liquid crystal for a right eye and liquid crystal for a left eye have the same construction. These liquid crystals make contrast with each other and then they are mounted on the liquid crystal shutter glasses portion. This makes it possible for each electrode to position in the center of liquid crystal shutter glasses portion. The construction in which the electric circuit is in the center of the liquid crystal shutter glasses portion makes it easy to make electric contact between the circuit and the electrode.

A flat CRT having a phosphor screen inclined with respect to the center axis of an electron beam and formed by applying phosphors to the inner surface of a tube wall. The tube inner surface is defined by rotating a plurality of logarithmic spiral curves having a constant angle of incidence and present in the x-y plane of a polar coordinate system in which the deflection center of the electron beam is its origin, the center axis extends through the origin and serves as the x-axis, and the y-axis extends through the origin and intersects the x-axis at right angles therewith. The spiral curves are rotated about the y-axis each through a specified angle to obtain a group of logarithmic curves defining the tube inner surface.

An object of the present invention is to provide a flexible printed wiring board and multilayered flexible printed wiring board in which, in methods of laminating substrates comprising a non-adhering section and an adhering section, adhesion of the FPC substrates of the flexure part can be prevented and adequate flex resistance can be maintained.The present invention provides a flexible printed wiring board comprising at least an electric insulating layer and a conductor layer wherein the surface of the electric insulating layer has a 10-point average roughness of at least 1.5 μm and less than 2.0 μm and contact angle of at least 60° and less than 120°, or has a 10-point average roughness of at least 2.0 μm and less than 4.0 μm, and also provides a multilayered flexible printed wiring board formed by the lamination of two or more of the flexible printed wiring boards in which the surface of the electric insulating layers of the two or more flexible printed wiring boards exposed in a bendable state are opposing in a non-adhered state, and a part of the wiring boards is laminated on each of a first multilayered flexible printed wiring board and a second multilayered flexible printed wiring board.
摘要:
An aqueous solution is formed by dissolving a dye made of alizarin and a humectant made of glycerin, and alkalized by dissolving a base (alkaline substance), thereby preparing a detector solution (101) in which the content of the humectant is about 20 wt %. An impregnated carrier (104) impregnated with the detector solution (101) is formed by dipping for 30 sec a sheet-like carrier (103) made of cellulose filter paper in the detector solution (101) so that the carrier (103) is impregnated with the detector solution (101). The impregnated carrier (104) is pulled up from the detector solution (101), and dried in dry nitrogen by evaporating a solvent such as water contained in the impregnated carrier (104), thereby forming an ozone detecting device (105).
