Title: Liquid crystal display device
Inventor: ISHII TOSHIYA
IPC: G02F1/1337
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal display device showing fast response and having excellent viewing angle characteristics by forming an optical compensation layer having the optical axes aligned in the direction to compensate the double refraction of the respective regions on at least either the upper or lower part of a plurality of minute regions having different alignment directions of the liquid crystal. SOLUTION: In this device, a color filter substrate is disposed between an optical compensation layer 2 and a polarizing plate 4, and a glass substrate with TFT(thin film transistor) formed is disposed between a lower alignment film 3 and a lower polarizing plate 4. The liquid crystal which constitutes the liquid crystal display device consists of two groups of molecules with optically compensated bend alignment. The alignment directions of the liquid crystal in the layer having the two groups of bend alignment differ by 90 deg. from each other. By aligning the two kinds of liquid crystal regions with 90 deg. difference in the alignment direction from each other, the best viewing angle characteristics can be obtd., which avoids the dependence of black display on the viewing angle or the dependence of white or middle tone display on the viewing angle.  Thus, a high contrast ratio can be obtd. in a wide viewing angle range.

Filed: 1988-03-24
Abstract: PURPOSE:To perform stable printing generating no positional shift, by constituting the title printer so that recording paper is held to a predetermined position by a holding means and a line head is moved by a moving means to perform printing. CONSTITUTION:In such a state that recording paper 2 is set to a holding means 5 and a line head 4 is brought into contact with the recording paper 2 under definite pressure through an ink sheet 3, the line head 4 is moved in the direction shown by an arrow A to perform printing.

Title: Cryopump
Inventor: KASHIBE MITSUNORI
IPC: F04B37/08
Filed: 1987-03-27
Abstract: PURPOSE:To obtain a cryopump whose gas discharge speed is variable, by providing a shutter means which may change the exposed area of a second panel for absorbing and trapping a low boiling point component, after a high boiling point component is absorbed and trapped from gas to be discharged by means of a baffle. CONSTITUTION:A shutter composed of a foldable thin film is secured at one end to a supporter 8 part and at the other end to a support 12 so that it is attached openably. A magnet 13 at the forward end of a support 12 is moved together with the shutter in association with the movement of a magnet 18 driven by a motor 19. Accordingly, the shutter 14 passes through a baffle 6 so that it may open and close its surface for exhaust gas such as N2, O2 or the like which is absorbed and trapped by a second panel 7. Further, since the shutter 14 is located downstream side of the baffle 6 in the direction of gas flow, no moisture and carbon oxide gas or the like are condensed on the shutter. Accordingly, it is possible to change the discharge speed satisfactorily without the rotation being stopped. Further, it is possible to prevent moisture and carbon oxide gas from being hindered in discharge to the baffle 6 even when the shutter 14 is fully closed.
