摘要:
The present invention relates to a structure of a liquid crystal (LC) cell using an antiferroelectric liquid crystal. The LC cell includes: an electrode substrate with color filters; an opposite electrode substrate; a first alignment film provided on the electrode substrate with color filters; a second alignment film provided on the opposite electrode substrate; an antiferroelectric liquid crystal provided between the first and second alignment films; and the electrode substrate with color filters and the opposite electrode substrate being superimposed so as to face each other through the first alignment film, the antiferroelectric liquid crystal, and the second alignment film. In the present invention, an alignment process of the first alignment film is performed based on a rubbing density larger than the rubbing density of the second alignment film so that an angle of layer rotation of the antiferroelectric liquid crystal is defined within a predetermined allowable angle range.

A second heating device heats an inner wall of an ink chamber of a print head to a temperature not lower than the melting point but not higher than evaporating temperature of ink 3, for a prescribed time period after the end of printing, based on a signal from a second heating control device. Consequently, the ink solidified and deposited on the inner wall of ink chamber and not used for printing is liquefied and recovered to the ink chamber to be used for the next printing.

An analog sampling circuit of a signal electrode driver of a matrix type liquid crystal device includes two pairs of FETs. During a first half of a select period of a scanning electrode, a first pair of serially connected FETs are deactuated while actuating one FET of the second pair of FETs to provide a signal voltage to a signal electrode of the display device. On the other hand, during the latter half of the select period, the first pair of FETs are actuated to provide an image signal voltage to the signal electrode.
摘要:
A linear motor is capable of reducing cogging which may be present in the motor. Cogging is an obstruction in realizing constant speed control or high accuracy of position control. The reduction of cogging is accomplished, for example, by pole location or specific detailed shapping of pole iron plates.

A method of checking the functioning of a driving wheel slip control system installed in a vehicle. Driving wheels are placed on support rollers and rotatably supported thereby. The driving wheels are driven by the engine. False signals indicative of tentative rotational speeds of trailing wheels are supplied to an ECU which in turn outputs a control signal for controlling the engine. Predetermined monitoring signals including at least the control signal output from the ECU are taken out from the driving wheel slip control system. It is determined whether the predetermined monitoring signals show values falling within respective predetermined allowable ranges. Further, a steering handle of the vehicle may be turned at the same time of rotation of the driving wheels, the steering angle of which is detected by a steering angle sensor. Further, instead of using the false signals, the trailing wheels may be placed on second support rollers for rotatably supporting the trailing wheels thereby. The second support rollers are capable of rotatively driving the trailing wheels.
摘要:
A hollow space of limited volume is defined in the central aperture formed through a heat-conducting plate, held in contact with a planar temperature-responsive resistance element, to receive the bimetal and heater supporting shaft. By varying the diameter and/or the length of the space, the rates of heat transmission from the heater to the bimetal and the resistance element can be properly correlated with each other so that any premature current control or overheating is effectively prevented.

An ozone generator generates ozone gas; a gas-liquid mixer mixes the ozone gas and a liquid; a liquid storage tank separates an introduced gas-liquid mixture into gas and a liquid; a circulation path circulates gas among the ozone generator, the gas-liquid mixer and the liquid storage tank; and an opening and closing control means controls a flow of gas flowing out through a gas outlet port of the liquid storage tank in accordance with a stored liquid amount in the liquid storage tank. As a result, the stored liquid amount of the liquid stored in the liquid storage tank can be adjusted.
