Title: Method and circuit for driving display device
Inventor: ETO SUNAO
IPC: G02F1/133
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To evade deterioration in display quality and display an image of high quality by suppressing variation in the mean potential of a data line within a constant range. SOLUTION: A unit driving circuit outputs output data to a corresponding voltage data line. The output data is updated at constant intervals of time and the voltage corresponding to the updated output data is outputted to the data line. In this case, the timing of the update of the output data is delayed by a specific delay time. This output data is updated halfway in the sampling of next data in the horizontal period right after the horizontal period of the output data based upon data sampled in one horizontal period. In the latter half part of one horizontal period and in the former half part of the next horizontal period, voltages having the positive and negative polarities corresponding to the same display data are outputted to the data line, so the mean potential of data lines for all pixels becomes constant without reference to the display data.

Title: Garbage disposer
Inventor: MIWA YOSHIYUKI
IPC: B04B7/08
Filed: 1989-11-25
Abstract: PURPOSE:To previously prevent that an inner cover is separated and broken at a time of dehydration and garbage in a vessel is scattered by providing a regulating member which inhibits an upper cover from being fitted to the regular position when a part to be stopped is in a nonstop state. CONSTITUTION:When an upper cover 30 starts to be fitted to a plate holder 3 at a time of a state wherein a clamp 26 is not stopped in a stopping part 16, namely of a state wherein an inner cover 18 is positioned in the placing position of a vessel 13, the upper end of the projecting part 23 of the inner cover 18 interferes in the lower end of an introduction port 31a and then the upper cover 30 can not be fitted to the regular position. Thereby it is judged that the inner cover 18 is not fixed to the pushing position and refitting of the inner cover 18 is promoted. Dislocation of the inner cover 18 and scattering of garbage are previously prevented. Further in this case, a reed switch is allowed to stand in an OFF-state in the state wherein the upper cover 30 is not fitted to the regular position. Even when a switch for dehydration is operated in this state, electricity is not conducted to a motor. Therefore it is more surely prevented that dehydrating operation is performed in a state wherein the inner cover 18 and the upper cover 30 are incompletely fitted.

IPC: G02F1/13
Filed: 1990-11-14
Abstract: PURPOSE:To convert a bright spot defect to a black spot defect and to easily obtain a liquid crystal display which has no problems in practicable use quality from the products which are defective originally by forming a layer contg. a material which exists on the surface of the liquid crystal corresponding to a picture element electrode to form the bright spot defect and can absorb the light leaking from the bright spot detect. CONSTITUTION:A display state is inspected by the layout of a pair of polarizing plates which are not in contact with each other to detect the bright spot defect part before these polarizing plates are stuck in the layout fixed to the surface of both electrode substrates. Namely, the liquid crystal of a normal operating part turns on to make black display when a voltage is impressed to all the picture element electrodes; however, the voltage is substantially not impressed to an abnormal part and this part remains as the initial bright spot defect. The light absorptive layer 13 is formed only in the position on the electrode substrate surface corresponding to this bright spot defect part. The formation of the light absorptive layer is executed by a method of uniformly dispersing a black pigment, such as carbon black, into a negative type photoresist, uniformly applying such photoresist on the substrate and exposing only the bright spot defect part to cure the resist and removing the rest to complete the formation.
