  • Publication number: 20100170440
    Abstract: The present invention has an object to provide a surface treatment apparatus, which can form a high-quality film at a high speed while preventing deterioration of the film due to collisions of charged particles. The surface treatment apparatus (1) of the present invention comprises a casing (2) partitioned to two chambers, that is, a plasma generating chamber (3) provided with plasma generating electrodes (5, 5?) and a substrate processing chamber (4) provided with a substrate supporting table (8). A plasma vent (6) is formed in the electrode (5?) that composes the partition between the chambers (3, 4). A conductive mesh-shaped sheet (9) is disposed in a direction across the plasma between the plasma vent (6) and a substrate (S) on the substrate supporting table (8). The sheet (9), to which a variable bias is applied, captures charged particles in the plasma so that the charged particles can be excluded from the plasma.

  • Patent number: 6952595
    Abstract: A digital broadcast channel reception system and a portable terminal allow watching a digital broadcast on the terminal. In the examples, a receiver unit for receiving digital broadcasts transmits video data to a display unit, using its TX data manipulator, modulator, TX circuit, and antenna. The TX data manipulator manipulates the output from an OFDM demodulator into data to transmit from the TX circuit and appends error correction codes to the data. The modulator modulates the output from the TX data manipulator. A display unit for digital broadcast display receives video data transmitted from the receiver unit, using its antenna, TX/RX section, and modulator/demodulator. After error correction codes in the received signals are decoded by a TX/RX data manipulator, video data is extracted. After the video data is decoded by a MPEG4 decoder, a picture is output on the display.

  • Patent number: 6796729
    Abstract: A shutter for a camera capable of opening a shutter sector in a reduced period of time includes a shutter opening formed in a shutter plate, shutter sectors for opening and closing the shutter opening, a drive lever having a drive pin for operating the shutter sectors, and an actuator for driving the drive lever. The drive pin penetrates through-holes formed in the shutter sectors. The through-holes have a size sufficiently large so that the drive lever is driven by the actuator substantially in a no-load state immediately after starting to drive the drive lever so that the shutter sectors are not moved until the drive pin has achieved sufficient acceleration.

  • Patent number: 6702484
    Abstract: A camera shutter has a base plate provided with a shutter opening. Sectors are mounted on the base plate to undergo movement to open and close the shutter opening. A driving lever has a driving pin that extends through through-holes in the sectors for operating the sectors. One of the through-holes is configured so that a gap is formed between an edge of the through-hole and the driving pin in the direction of movement of the driving pin. As the driving pin moves to drive the sectors to close the shutter opening, the movement of the driving pin is abruptly stopped when the sectors fully close the shutter opening thereby causing the driving pin to rebound. The rebounding motion is not transmitted to the sector in which the gap is formed, and inertia permits further movement of the sector in the closing direction over a distance equal to the gap. This maintains the sectors in overlapping relation and prevents reexposure when the shutter is in a fully closed state.

  • Patent number: 6491450
    Abstract: To prevent rebounding motion of sectors caused in stopping the sectors and achieve small-sized formation of a shutter, there is provided a shutter for a camera including sectors for opening and closing a shutter opening by reciprocal and pivotal movement, a motor for reciprocally and pivotally moving the sectors by forwardly and reversely rotating a rotor of the motor by applying current to a coil in forward and reverse directions, a control circuit for controlling current applied to the coil for exposure control in accordance with a brightness of an object to be photographed and a memory circuit for outputting data used for applying current to the control circuit in correspondence with operational characteristics of the motor and the sectors. The memory circuit is provided with current data for applying current to the coil for rotating the rotor in a direction reverse to a rebounding direction of the sectors to prevent a rebounding motion of the sectors.
