    Abstract: An input disk and a clutch disk are supported by an output shaft in such a manner that the input disk is rotatable relative to the output shaft, and the clutch disk is non-rotatable relative to and is axially movable relative to the output shaft. When a large load torque is exerted about the output shaft, relative rotation between the input disk and the clutch disk occurs. A connecting rod has one end connected to a worm wheel, and is reciprocally swung through rotation of the worm wheel. A rotatable lever has one end, which is connected to the other end of the connecting rod, and has the other end, which is engaged with and is secured integrally with the gear teeth of the input disk.

    Abstract: A liquid crystal panel (10) includes an active matrix substrate on which a transistor (12), a pixel electrode (17), signal lines (15, 16) and backup wirings (8a, 8b) for recovering a defect in the signal line are formed; a color filter substrate on which a common electrode (counter electrode) is formed; and a liquid crystal material provided between the active matrix substrate and the color filter substrate. The backup wirings (8a, 8b) are (electrically) connected to the common electrode on the color filter substrate, through (i) a protection circuit (9) for discharging an undesired electric charge that occurs in the backup wirings (8a, 8b) and (ii) a sealing adhesive (6). With this configuration, it becomes possible to reduce problems (for instance, unexpected short-circuiting of the backup wiring and the signal line) caused by the undesired electric charge that occurs in the backup wirings.

  • Publication number: 20090195488
    Abstract: A segmented-pixel liquid crystal display has a plurality of pixels of which each has three sub-pixels 10a-10c, namely one middle and two side sub-pixels, arranged next to one another in the column or row direction. The sub-pixels 10a-10c have different brightness levels when the pixel as a whole is in a given middle halftone state, and the middle sub-pixel 10a has the highest brightness level. This eliminates unnaturalness as is conventionally produced when an image with a straight border is displayed, and further improves the gamma characteristic.
