  • Publication number: 20070112107
    Abstract: At least one resin component which is selected from a biodegradable resin and a plant-based resin, and a flame retardancy-imparting component are kneaded to obtain a resin composition having flame retardancy. This resin composition makes it possible to apply the environment-friendly resin such as the biodegradable resin and the plant-based resin, for example, polylactic acid and polybutylene succinate to exterior bodies of home appliances. Particularly, in the case where polylactic acid is used with the acetylacetonatoiron as the flame-retardant component, a resin composition having excellent flame retardancy can be provided as a non-halogen material.

  • Patent number: 6800008
    Abstract: A method and an apparatus for removing a film from a display panel are provided that can remove even a film with relatively high strength that is stuck on a display panel without relying on manual work and also can reduce the operating cost. The apparatus that removes a film stuck on a display panel by injecting a liquid includes a liquid injector and a carrier. The liquid injector injects the liquid in the direction that tilts with respect to a normal to the surface of the display panel on which the film is stuck. The carrier transports the display panel. The liquid injector starts the injection of the liquid at the boundary between one end of the film and the display panel on the side of the transport direction. The liquid is injected while transporting the display panel so that the film is removed successively from one end to the other end in the opposite direction to the transport direction.

  • Patent number: 6425672
    Abstract: A reflecting film is made by forming resin layers on both sides of a metal thin film, and using a colorless, transparent, and optically isotropic material at least in one resin layer. A reflecting film is made by forming a metal thin film on one side of a resin film, and forming a colorless, transparent, and optically isotropic resin coat layer on its surface by printing or other method. A mirror having such a reflecting film is mounted on a frame. A projection type image magnifying apparatus for liquid crystal panel and a projection type image magnifying apparatus for CRT, improved in resolution and contrast ratio, is obtained by using such mirror as an image reflecting mirror.

  • Patent number: 5058821
    Abstract: A coil bobbin includes a main cylinder portion opened at both ends around which a coil is wound, and a leader cable accommodating groove portion disposed in a manner surrounding the main cylinder portion at one end of the main cylinder portion on an outer peripheral surface of the main cylinder portion. The leader cable accommodating groove portion includes a leader cable front end accommodating portion for accommodating a front end of a leader cable, and the leader cable front end accommodating portion has a radialwise width, being smaller than a radialwise width of an inner portion of the leader cable accommodating groove portion, at a portion adjacent to an opening of the leader cable accommodating groove portion. Hence, the coil bobbin not only holds the leader cable in the leader cable accommodating groove portion stably, but also inhibits the leader cable from coming off the leader cable accommodating groove portion outward in an axial direction with the leader cable front end accommodating portion.
