  • Patent number: 6804889
    Abstract: A holder 20 is rotatably connected to a body 10. A scribe tool 30 is attached to one end of the holder 20. A plate spring 16 is fixed to the body 10, and a receiving plate 26 is fixed to the holder 20. A piezo-actuator 40 is interposed between the plate spring 16 and the receiving plate 26. One end of a plate spring 50 having a small spring constant is fixed to the holder 20. The body 10 is provided with an adjustment screw 60. When a lower end part 65 of the adjustment screw 60 is protruded, the lower end part 65 presses the plate spring 50 for flexure, thereby generating a resilient force to the plate spring 50. By this, a rotational force is given to the holder 20 and thus a pressing load directing toward a workpiece is given to the scribe tool 30.

  • Patent number: 6470782
    Abstract: A scribe device comprises a body (10). A holder (20) is supported by the body (10) such that the holder (20) can slightly slide in a direction of a slide axis (Lb) which intersects a surface of a workpiece (100). Retaining portions (15, 21) spaced apart in a direction of the slide axis (Lb) are formed on the body (10) and the holder (20), respectively. A vibratory actuator (40) is sandwiched between the retainer portion of the body and the retainer portion of the holder. The holder (20) holds an abutment member (30). The holder is biased by a biasing member (23) such that said retaining portion of the holder is pressed against the vibratory actuator. The vibratory actuator renders the vibrations in the direction of the slide axis to the holder. The abutment member transmits the vibrations from the holder to the workpiece. That is, the abutment member (30) is subjected to a static force and a vibration energy and pressed against the workpiece (100).

  • Patent number: 5751392
    Abstract: One end of a vacuum evacuation passage is connected to a suction port of a cell and one end of a liquid crystal supply passage is connected to an introduction port of the cell. In that state, an internal space of the cell is evacuated through the vacuum evacuation passage and the suction port. Thereafter, a pressurized liquid crystal is supplied to the internal space of the cell through the liquid crystal supply passage and the introduction port while evacuating the internal space of the cell. After the completion of a liquid crystal filling operation to the internal space of the cell, the supply of the pressurized liquid crystal is stopped and the level of the negative pressure in the vacuum evacuation passage is gradually eased to the level of the atmospheric pressure.

  • Patent number: 5638876
    Abstract: A liquid crystal introduction connector includes a connector body. The connector body has a guide groove formed in its front surface and a receiving space formed backwardly of the guide groove. A resilient seal member is received in the receiving space. A nozzle member is allowed to extend through the seal member such that the nozzle member can move forwardly and backwardly. The nozzle member is biased forwardly by a spring. When a side edge of a cell having an introduction port is inserted through the guide groove, the seal member is resiliently deformed to receive the side edge. Under the effect of the spring, the nozzle member is brought into abutment with the side edge of the cell. The liquid crystal passes through a liquid crystal supply passageway and reaches the introduction port of the cell via nozzle ports of the nozzle member.

  • Patent number: 5461502
    Abstract: An apparatus for feeding a liquid crystal includes a support member having a rotational axis and capable of rotating about the rotational axis. A thin container is supported by the support member. In that supporting condition, an air discharge port of the container is near to the rotational axis, a liquid crystal feed port is away from the rotational axis, and the air discharge port is open to the atmosphere. The liquid crystal is fed through the feed port while rotating the support member about the rotational axis. Rotation of the support member causes a centrifugal force to be applied to a leading edge of the liquid crystal which has been fed in the container, the direction of the centrifugal force being reverse to a proceeding direction of the leading edge.
