  • Publication number: 20140320943
    Abstract: An optical scanning device has a reflecting portion and a supporting body for supporting the reflecting portion. The reflecting portion has a reflecting surface for reflecting light beam. A pair of outside beam members is arranged between the reflecting portion and the supporting body in a longitudinal direction of the device. The device also has a first driving portion, one end of which is connected to the supporting body, while the other end of which is connected to a driving point of the reflecting portion.

  • Patent number: 6779198
    Abstract: A transport stream is received and recorded, and the recorded transport stream is reproduced normally. A cycle timer generates a time stamp based on a clock generated by means of a clock generation circuit that is independent of the system clock generated by means of a built-in PLL of an AV decoder, a receiver adds the time stamp to a TS packet, and the TS packet is recorded in a hard disk. On the other hand, a transmitter supplies the TS packet read out from the hard disk to the AV decoder by way of a switch, MVLink-IC, DEMUX, and FIFO memory at the timing so that the time interval between adjacent TS packets is coincident with that of the time when it was received based on the time stamp added to the TS packet.

  • Patent number: 6508168
    Abstract: A stencil printer includes a printing drum which has an ink-permeable peripheral wall and is rotated about a predetermined axis of rotation with a stencil master wound around the peripheral wall, a back press roll which associates with the printing drum to nip and convey a printing paper, and an internal press roll which is provided in the printing drum to be movable back and forth toward and away from the back press roll and pushes the peripheral wall of the printing drum toward the back press roll. An internal press roll drive mechanism moves back and forth the internal press roll between a first position where the internal press roll is held away from the back press roll and a second position at a distance from the first position toward the back press roll and is able to freely change the distance between the axis of rotation of the printing drum and the second position.

  • Patent number: 6343379
    Abstract: A receiver, such as that used in broadcasting, is provided with a simplified structure for storing and updating the receiver's control program and for preventing a loss of the control program because of a power outage during such updating. The structure includes a first storage means comprising an erasable, non-volatile memory and a second storage means comprising a volatile memory. The control program is stored in the first storage means and is executed to download and store a second program in the second storage means. The second program then is executed to download and store an updated version of the control program in the first storage means.

  • Patent number: 5099329
    Abstract: The first difference signal between the current and previous frame signals is obtained by the subtracter pixel by pixel and supplied to both the line memory and the average value calculation circuit. The average value calculation circuit calculates the average value for at least one line of the first difference signal which relates to only pixels with smaller absolute of the difference value than the present threshold. If the pixels which have absolute values smaller than the threshold, are less than the present number, the average value is set 0. Large values of the first difference caused by motion of the target are excluded and not treated as the flicker noise. The second difference signal is transformed by the non-linear circuit according to predetermined characteristics and supplied to the adder. The previous frame signal is supplied to the adder at the same time by delaying the signal through the line memory.
