  • Patent number: 6184970
    Abstract: A master plate transporting system automatically detects the presence/absence of master plates accommodated in a container and also detects the position of each master plate in the container as well as the type of the container being used. In this arrangement, the master plate transporting system executes the automatic transporting operation without transport errors. Containers each holding one or more reticles, are positioned in a semiconductor manufacturing apparatus. A reticle detection sensor detects the presence and the position of the reticle in each container. A controller controls the transporting operation of a reticle transporting mechanism based on the detection results of the detection sensor to reliably retrieve the reticle, transport it to an exposure system, and return it to the container.

  • Patent number: 6163386
    Abstract: In a photoelectric conversion device for reading signals in succession from plural photoelectric converting elements (S11-S33), arranged two-dimensionally on a substrate, by successively scanning drive lines (g1-g3) in the X-direction thereby transferring signals charges along signal lines in the Y-direction, for reading the signals of the photoelectric converting elements in a partial area, only the arbitrarily selected drive lines for the plural photoelectric converting elements are scanned in succession while the remaining drive lines are not driven or are driven simultaneously for transferring the charges at a timing different from the timing of drive of the arbitrarily selected drive lines.

  • Patent number: 6046446
    Abstract: A high S/N ratio, stable, and high read rate photoelectric conversion device is formed by the same process as that for a TFT in a photoelectric conversion apparatus, and includes a photoelectric conversion device having a first electrode layer, a semiconductor layer, and a second electrode layer, first and second switch devices each having first and second main electrodes, first and second power sources, and a reading circuit, where the first electrode layer is electrically connected to the first main electrode, the second electrode layer is electrically connected to a power source, and the second main electrode is electrically connected to the reading circuit. The switch device is turned on in refresh driving for applying an electric field from the power source to the second electrode layer in a direction for guiding carriers from the semiconductor layer to the second electrode layer, thereby fixing a potential on a first electrode layer side of the photoelectric conversion device.

  • Patent number: 5743187
    Abstract: In a plate clamping device of a printing press for clamping a plate by a bottom clamping rail and a pressure plate, chips hardened to form serrations inclined in the lateral direction of a plate clamp so as to bite the plate in the direction of slipping-off of the plate are embedded in the clamp surfaces of the bottom clamping rail and the pressure plate such that the serrations on the bottom clamping rail side and the pressure plate side are inclined in opposite directions. Thus, the plate can be held with sufficient force without plastic deformation of the end of the plate, and the plate can be reused.

  • Patent number: 5511817
    Abstract: A vehicle axle suspension system including wheel support members for rotatably supporting road wheels, a suspension member for supporting the road wheel support members for vertical swinging movement, and elastic suspension elements. The elastic suspension elements include a pair of front elastic suspension elements provided at different suspension points in front of the road wheel support members for elastically mounting the suspension member to the vehicle and a pair of rear elastic suspension elements provided at different suspension points behind the road wheel support members for elastically mounting the suspension member to the vehicle. The elastic suspension elements are positioned to provide an understeer characteristic when a lateral force acts on a suspension roll center determined by suspension geometry to rotate the suspension member around a virtual roll axis extending through an elastic center of the front elastic suspension elements and an elastic center of the rear elastic suspension elements.

  • Patent number: 5104142
    Abstract: A wheel alignment adjusting mechanism for a rear suspension system for an automotive vehicle. The wheel alignment adjusting mechanism is comprised of a rear upper link for movably connecting a wheel supporting member and a bracket projection from a suspension member assembly. The rear upper link is pivotally connected at one end thereof with the bracket through a pivot pin. The pivot pin is movably fitted within elongate openings which are formed respectively in two side plate sections of the brackets. The longitudinal axis of each elongate opening inclines to be lowered in the outboard direction by an angle of 30 degrees relative to a horizontal plane in a vehicle body, thereby maintaining smaller change amounts in wheel alignment along with suspension stroke.
