  • Patent number: 8188983
    Abstract: A touch panel includes: a first substrate; a second substrate disposed to face the first substrate; an annular seal material that adheres peripheries of the first substrate and the second substrate to each other so as to set a gap between the first substrate and the second substrate; first seal portions that adhere corner portions of the first substrate and the second substrate through the seal material; and second seal portions that are in connection with the first seal portions and adhere side portions of the first substrate and the second substrate through the seal material. Each of the first seal portions has a thickness which is smaller than each of the second seal portions so that the substrate gap is set to be small.

  • Patent number: 7446836
    Abstract: A transflective liquid crystal display device includes a first substrate including first electrodes; a second substrate including second electrodes; a liquid crystal material interposed between the first and second substrates; and a display region including a plurality of pixels each having a reflective region and a transmissive region. The reflective and transmissive regions are arranged in strip shapes lying across pixel rows. The first substrate includes a layer-thickness adjusting layer adjusting retardation in the reflective and transmissive regions. The layer-thickness adjusting layer includes thick portions arranged in the reflective regions; thin portions arranged in the transmissive regions; step portions formed in the display region at boundaries between the thick and thin portions such that inclined planes are formed in a vertical direction; and relieving portions formed outboard the display region to reduce a step difference between the thick and thin portions.

  • Publication number: 20060061716
    Abstract: An electro-optical device includes a pair of substrates with an electro-optical material layer interposed therebetween, and a plurality of pixels, each having a reflection region and a transmission region. The reflection regions are disposed on opposing sides of adjacent pixels. On one substrate of the pair of substrates, an insulating layer is formed in the reflection region, such that the thicknesses of the electro-optical material layer in the reflection region and the transmission region are made different from each other. Further, the insulating layer is formed across two adjacent pixels along a direction in which the reflection regions of adjacent pixels continue.

  • Patent number: 4728079
    Abstract: A cable pulling apparatus includes a driving sheave on which is wound a tow line detachably connected to one end of a cable to be pulled; a pulling device disposed between the driving sheave and the end of the tow line and adapted to pull the tow line, a tension detector disposed between the driving sheave and the end of the cable and adapted to detect the pulling tension in the cable, and a control means for controlling the traction device in accordance with the tension detected by the tension detector such that, when the tension detected by the tension detector is below a predetermined limit, the pulling speed is controlled to impart a tension which is comparatively small but large enough to prevent any slip of the tow line on the periphery of the driving sheave, whereas, when the tension detected by the tension detector exceeds the predetermined level, the pulling speed is decreased such as to cause a slip of the tow line on the outer periphery of the driving sheave.
