  • Patent number: 6298888
    Abstract: Disclosed herein is a new kind of veneer which has the cross grain (such as wavy grain and interlocked grain) artificially formed on the surface of straight-grained veneer cut by quarter sawing from a species of wood which should yield the cross grain but actually has no cross grain. Disclosed also herein is a method of producing the cross-grained veneer, said method comprising cutting wood into veneer of desired thickness which assumes the straight grain, by using a veneer peeling machine equipped with a knife whose cutting edge waves continuously in the lengthwise direction, and flattening the veneer having an uneven surface by means of thermal fixing or hot pressing, thereby artificially forming the cross grain on the surface of the straight-grained veneer. The knife is constructed such that the cutting edge waves in the widthwise direction of the knife and the troughs of the wave are disposed along the straight line extending in the lengthwise direction of the knife.

  • Patent number: 4963985
    Abstract: A still video camera includes a solid-state image pickup device including a photosensor section, a vertical transfer section for vertically transferring charge from the photosensor section, and a horizontal transfer section for outputting the charge from the vertical transfer section to the outside. The solid-state image pickup device is arranged to change an exposure time. Exposure is started at an end of transfer of the charge from the photosensor section to the vertical transfer section. Emission of an electronic flash is started on the basis of a predetermined shutter speed when a predetermined period of time has elapsed. The charge of the photosensor section in the solid-state image pickup device is transferred to the vertical transfer section when an amount of light reflected by an object to be photographed reaches a predetermined value, thereby completing the exposure.

  • Patent number: 4672456
    Abstract: An apparatus and method for the automatic focussing of a video camera having a camera circuit for generating electric image signals corresponding to the brightness of an object, a circuit for sampling at least two sampling signals from the electric image signal, an A/D converter for obtaining at least one inclination value corresponding to at least one pair of the sampling signal, and a stop for stopping a focussing lens when at least one of the inclination values exceeds a predetermined value.
