  • Patent number: 7880781
    Abstract: A solid-state image pickup apparatus selects, in a first image pickup circumstance in which dark current is liable to occur in vertical transfer paths of an array of photo-sensors, a first transfer mode in which the potential well capacity in the vertical transfer paths is relatively small, and, in a second image pickup circumstance in which the dark current is small in quantity, a second transfer mode which is greater in potential well capacity than the first transfer mode. As a positive voltage applied to the read-out gates of the photo-sensors, a first voltage mode indicating a relatively low positive voltage that suppresses impact ionization is set in the first image pickup circumstance, and, a second voltage mode indicating a positive voltage higher than in the first voltage mode is set in the second image pickup circumstance so as to cause the impact ionization.

  • Patent number: 5424522
    Abstract: A card convey device includes a card convey unit, a punching unit, a counting unit, and a control unit. The card convey unit selectively conveys a card in a discharging direction and an opposite direction thereto. The punching unit punches the card which slows down, while the card is conveyed by the card convey unit in the discharging direction. The counting unit is enabled after a punching operation is performed by the punching unit, and counts the number of times of repetition of a reciprocal card convey operation in the opposite direction and the discharging direction. The control unit controls a convey operation of the card convey unit and repeatedly reciprocally conveys the card in the opposite direction and the discharging direction until the count value of the enabled counting unit reaches a predetermined count value. When the count value of the counting unit reaches the predetermined count value, the control unit conveys the card in the discharging direction and discharges the card.

  • Patent number: 4874153
    Abstract: The invention provides a process for producing ceramic products using, as one of the materials, the sludge obtained by sewage treatment. The invention thus not only makes the sludge treatment unnecessary, but makes the sludge useful as a material for products. A plastic ceramic raw material and, if required, another raw material are added to either the sludge or the ashes obtained by burning the sludge, so as to prepare a body. The body thus obtained is molded into a desired shape, and fired to produce a ceramic product. The firing process prevents the product, containing the sludge, from emitting an offensive odor or being decomposed. The product may be used as a tile, brick block, or the like. Production conditions such as the proportion of each raw material used and the like may be suitably selected to obtain a ceramic product with a desired characteristic in respect of water permeability, from almost no permeability to a very high permeability.
