  • Publication number: 20100231831
    Abstract: 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.

  • Publication number: 20100060830
    Abstract: A method of easily manufacturing a light diffusion film by a continuous process, which achieves both good display properties and an increase in viewing angle when used in a liquid crystal display. A method of manufacturing a light diffusion film includes forming a laminate of an original light diffusion film and a photosensitive resin, wherein the photosensitive resin includes at least two types of materials that are different in refractive index from each other; and irradiating the laminate with a collimated laser beam from a side of the original light diffusion film, wherein a reflection hologram formation-preventing layer is located on a side of the laminate opposite from the side of irradiation of the laminate with a collimated laser beam. In the process of irradiating the laminate, the reflection hologram formation-preventing layer prevents formation of a reflection hologram on the photosensitive resin due to a reflected light from the irradiation.

  • Publication number: 20100051734
    Abstract: 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.

  • Publication number: 20100051733
    Abstract: A pretensioner is provided, of which the cylinder, including a restriction portion, can be inexpensively formed, the cylinder having the restriction portion for positioning a gas generation unit to be mounted to a cylinder, and a pretensioner manufacturing method for manufacturing such a pretensioner is provided. In the pretensioner, since the cylinder is molded by forging, an inexpensive material compared with a stainless pipe member can be used for the molding. In addition, since the positioning portion can be molded during forging-molding for molding the entire cylinder, cost can be reduced even in this regard.

  • Publication number: 20090244447
    Abstract: A directional diffusion film with diffusion properties that vary depending on the incidence angle is characterized in that a diffusion axis direction is in the range of 20° to 50° with respect to a normal direction of the film, and a diffusion half-value angle is at least 20° and lower than 90°. The diffusion axis direction is a light irradiation direction in which the strongest diffusion light is obtained when the film is irradiated with light. The diffusion half-value angle is a diffusion angle at which intensity of outgoing diffusion light at a plane A is 50% of the peak intensity, with the plane A containing the normal direction and the diffusion axis direction of the directional diffusion film, when collimated light is incident at an incidence angle of 30° from the normal direction of the directional diffusion film in the plane A. A polarizing plate containing the directional diffusion film. An LCD device containing the directional diffusion film.

  • Publication number: 20080007389
    Abstract: A determination is first made on the presence or absence of input of an advance application number as advance application information (S2). Here, when it is determined that the input is present (Y in S2), the advance application number and a reception number as identification information for identifying a wireless tag handed to an attendee, are registered as entrance information in an attendee management table being a database in association with each other (S7 and S14). Meanwhile, when it is determined that the input is absent (N in S2), the reception number is registered as entrance information in the attendee management table (S12 and S14). Hence, it is made possible to hand IC tags to all attendees promptly to complete an entrance reception in a short period of time, and therefore it is possible to smoothly perform the entrance reception.

  • Publication number: 20070128370
    Abstract: 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.
