  • Patent number: 5721971
    Abstract: A wireless slave electronic photoflash device is located separately from a camera body, and responsive to light emission of a master electronic flash unit built in or connected to the camera body, for emitting light synchronized therewith. The slave flash device includes a discharge tube, a trigger section responsive to a trigger signal for causing the discharge tube to emit light, a photodetector adapted to detect an optical signal from the master flash device, a one-shot section which is retriggerable and generates and issues a signal during a predetermined time period in response to the receipt of a signal from the photodetector, and a trigger signal output section which generates and issues the trigger signal based on the signal from the one-shot section and the signal from the photodetector.

  • Patent number: 5708891
    Abstract: A camera has barrier supported by a rail block attached to the body of the camera and movable from a fully closed position where the barrier entirely covers the front of an imaging lens to a fully opened position where the barrier is fully retracted clear of the front of the imaging lens. At its fully closed position and fully opened position, the barrier clicks when a ball is pressed into contact with a cam formed on the rear surface of the barrier. Projection of the ball is restrained by a slip-off prevention portion of the rail block so that the barrier is not subjected to an excessive urging force. In the camera, the barrier is not subjected to an unnecessarily large urging force and is less likely to lift away from the camera. The advantage is particularly great if the barrier in use is narrower than the outer diameter of a lens barrel.

  • Patent number: 5708895
    Abstract: A camera whose body is wound with a belt-like protective cover having an end detachably held by pin members thereon in such a manner as to cover a wall surface thereof. The protective cover is operative to cover and protects at least a photographing lens, a distance measuring or range finder window and a stroboscopic window. Thus, the camera is put into an enclosed state. Further, the enclosed state, in which the protective cover is wound around the body of the camera, is maintained by fitting a magnet hook attached to the other end of the protective cover into another magnet hook attached to the body of the camera and making these magnet hooks attracted to each other. Moreover, when putting the camera into a ready-to-photograph state, the protective cover is unwound by removing the magnet hooks from each other and opening the photographing lens and so on.

  • Patent number: 5701533
    Abstract: A camera with a lens mount having an imaging lens and a barrier which is disposed on a camera body and which is shiftable between a closed position where the barrier covers a part of the lens mount and the entire front of the imaging lens and an open position where the barrier is clear of the front of the lens mount. When the barrier is at the closed position, the barrier allows the front of the lens mount to be partly exposed. The camera thus constructed achieves a minimum dimension in the width across the camera body including the barrier.

  • Patent number: 5677760
    Abstract: A rangefinding device for use in a camera comprising a projection section for projecting a light beam emitted by a light source through a projection lens to an object, a light pickup section disposed diagonally opposite from the projection section that picks up, on its light pickup element, light reflected off the object, two-dimensionally senses the light, and outputs incident light position information, a CPU for computing the range to the object based on the output of the light pickup section and an attitude sensor section for sensing the orientation or attitude of the camera. In response to the output of the attitude sensor section, the CPU computes the range to the object based on the incident light position information in either the vertical direction or horizontal direction of the photographing frame, output by the light pickup section.

  • Patent number: 5658642
    Abstract: Method and apparatus for producing a protective covering for beds or the like comprised of a first thermoplastic web, a pair of fibrous mats of substantial loft, said web and mats being bonded together in accordance with a quilted pattern utilizing a thermoelectric bonding technique. The bonding layer, which is preferably polyurethane or a derivative thereof, forms an excellent bond with both the web and the fibrous mats. The fibrous mats provide excellent moisture absorbency and are breathable since the fibrous mats are bonded to the web only at the limited areas defined by the pattern. The first web provides an excellent waterproof barrier, while the mats provide an array of puffed-up regions each delineated by the bonding pattern to yield an aesthetically appealing cover which may be used with either fibrous web exposed.

  • Patent number: 5653776
    Abstract: Apparatus for scrubbing a gas in which a vortical flow of a gas and liquid mixture created by an entrainer is introduced into a de-entrainer through a guide/deflector assembly. Particulate is removed from the gas and picked up by the liquid during entrainment. De-entrainment separates the liquid from the gas and delivers the scrubbed gas to an outlet. A conical top provided upon the primary de-entrainer prevents water droplets, which also contain particulate from being re-entrained with the scrubbed gas and further serves to deflect the droplet toward the sides of the de-entrainer where they may be collected, filtered and returned to the entrainer, thereby significantly increasing contaminant removal from the gas stream.
