  • Patent number: 5694620
    Abstract: A camera device comprises a photosensitive film, a frame connected to the film for holding the film fixed in a plane, a plurality of lenses having respective focal lengths, and a plurality of spring loaded brackets equal in number to the lenses. The brackets removably mount respective lenses to the frame and are dimensioned for holding the lenses at respective focal positions relative to the film. Releasable locking elements equal in number to the lenses are attached to the frame in operative engagement with respective brackets for holding the brackets in collapsed pre-usage configurations in opposition to spring forces tending to expand the brackets and position the lenses at the respective focal positions. A plurality of shutters equal in number to the lenses are mounted to the frame for enabling light transmission selectively from the lenses onto the film.

  • Patent number: 5693382
    Abstract: Disclosed is a frame-supported pellicle, which is an integral body consisting of a rigid frame and a transparent plastic film adhesively bonded to one end surface of the frame in a slack-free fashion, for dustproof protection of a photomask used in a photolithographic patterning work in the manufacture of fine electronic devices such as LSIs and liquid crystal display panels. The frame-supported pellicle is prepared by bonding the frame and plastic film with an adhesive having a glass transition temperature substantially lower than that of the polymeric resin forming the film and the adhesive bonding work is performed at a temperature higher than the glass transition temperature of the adhesive but lower than that of the polymeric resin of the film so that excellent adhesive bonding strength can be obtained between the frame and the resin film still without causing any adverse influences on the resin film such as distortion and crease formation.

  • Patent number: 5694180
    Abstract: In a projection system for projecting a video picture composed of picture points on a screen with at least one light source which emits a light bundle and can be varied in intensity and with a deflecting device which deflects the light bundle to illuminate the picture points on the screen, a transformation optical system having at least two stages is arranged between the deflecting device and the screen and is corrected according to the tangent condition so as to be free of distortion. The transformation optical system has at least two optical stages. The first optical stage produces an intermediate image plane which is imaged on the screen by means of the subsequent optical stage (s).

  • Patent number: 5682644
    Abstract: The self-closing hinge assembly has a pair of cam members which are biased against each other by a pair of coil springs. The outer coil spring serves to bias the cam members together under a first restoring force and is effective during an initial opening of a door, for example to a 90.degree. position. The second inner spring becomes compressed only after the outer coil spring has been compressed. Compression of the second coil spring occurs as a door is opened beyond the 90.degree. position. The door may be held in one of two dwell positions corresponding to the cam surfaces on the movable cam member.
