  • Patent number: 5336132
    Abstract: A ship, in which stereoscopic imagery is displayed, can move, and the ship can swing in various directions and can vibrate. The ship moves along a guide path while the stereoscopic imagery is being viewed by inside viewers. The guide path includes a plurality of diverging guide paths midway along the guide path. The ship can freely select one of the diverging paths in accordance with the contents and running time of imagery. The ship, which has passed the diverging guide path, passes through a confluence portion and returns to the start position. Thereby, multisensation can be created, and an effective sensation atmosphere can be created on the basis of visual and other senses, with a small space for installation and low costs.

  • Patent number: 4876177
    Abstract: A process for producing a printed circuit board, which comprises the steps of forming a layer comprising a photosensitive resin composition on an insulating substrate having on its surface an adhesive layer adherent to a metal being subsequently plated thereon; exposing said layer comprising a photosensitive resin composition to an actinic radiation in a manner so as to form on said layer a negative pattern of a conductor circuit pattern and to semicure said negative pattern to an extent sufficient to keep it from erosion by a plating solution; developing by dissolving away with a solvent the uncured areas not exposed to said actinic radiation, thereby to form a plating resist on the areas of said negative pattern; chemically plating said conductor circuit pattern areas not covered with said plating resist, thereby to form a conductor circuit; and carrying out a curing treatment to cure completely said resist.

  • Patent number: 4604160
    Abstract: This invention concerns a method for the manufacture of a printed wiring board which particularly proves useful as a printed coil. This method is characterized by the fact that in the work in process which has undergone the step for formation of a conductor circuit and which has not undergone the step for separation of a plating resist, the plating resist and other insulating substratal material are separated for transfer from the surface of the substrate having the conductor circuit formed thereon.Since this method permits formation of an extremely thin insulating layer and a conductor circuit layer thicker than the insulating layer, it enables production of very thin printed wiring board and printed coil having high circuit density in the surfaces of component layers as well as in the direction of superposition of component layers.
