  • Patent number: 6693249
    Abstract: An inhibitor switch is used to correctly perform the detection of speed change positions. This inhibitor switch has a terminal block with fixed contacts and a moving block which is mounted and fitted onto a manual shaft of an automatic transmission, has a signaling contact and large capacity current-carrying contacts, and is rotatable relative to the terminal block. This inhibitor switch is used for electrically detecting a speed change position of the automatic transmission on the basis of a relative rotating positional relationship of the fixed contacts and the signaling contact in accordance with the rotation of the manual shaft. The moving block, which is mounted on the manual shaft, has a boss portion formed of a resin and a contact support portion whereon the signaling contact and large capacity current-carrying contacts are mounted. The contact support portion is formed of metal and the signaling contact is joined to the contact support portion by caulking.

  • Patent number: 6693258
    Abstract: A polycrystalline thin film of good quality is obtained by improving a crystallization process of a semiconductor thin film using laser light. After conducting a film forming step of forming a non-single crystal semiconductor thin film on a surface of a substrate, an annealing step is conducted by irradiating with laser light to convert the non-single crystal semiconductor thin film to a polycrystalline material. The annealing step is conducted by changing and adjusting the cross sectional shape of the laser light to a prescribed region. The semiconductor thin film is irradiated once or more with a pulse of laser light having an emission time width from upstand to downfall of 50 ns or more and having a constant cross sectional area, so as to convert the semiconductor thin film contained in an irradiated region corresponding to the cross sectional area to a polycrystalline material at a time. At this time, the energy intensity of laser light from upstand to downfall is controlled to apply a desired change.

  • Patent number: 6683595
    Abstract: An object of the invention is to improve moving-picture quality of an active matrix type liquid crystal display apparatus. The apparatus comprises liquid crystal pixels disposed in matrix configuration, a line drive circuit sequentially scanning each line of the pixels at every frame repeating with a predetermined frequency, and a column drive circuit writing image signal into the pixels in sync with the sequential scanning. The frame is divided into a preceding and following sub-frame. The line drive circuit scans sequentially for the preceding and following sub-frame. The column drive circuit writes image signal originally assigned to a frame into the pixels for the preceding sub-frame, and then writes an image signal for adjusting image quality into the pixels for the following sub-frame. The image signal for adjusting image quality is obtained by operating the image signal assigned to the frame and an image signal assigned to the next frame.
