IPC: G02F1/133
Filed: 1989-09-12
Abstract: PURPOSE:To nearly completely eliminate the dependency on the visual angle of the liquid crystal display device by utilizing a film which has an optical axis or ray axis substantially in the normal direction thereof in combination with a uniaxially stretched film. CONSTITUTION:The film which has the optical axis or ray axis in substantially the direction perpendicular to the plane is usable. Namely, the film having at least one optical axis or ray axis within 45 deg. circumference from the normal direction of the plane is satisfactory and, therefore, the films which are not in zero in the retardation in the perpendicular direction are also included. Even if the optical axis or ray axis is not within 45 deg. circumference, a satisfactory result is obtd. if the film satisfies the conditions etaTH-etaMD+etaTD/2>0 where the refractive index in the plane direction of the film is designated as etaTH, the refractive index in the longitudinal direction of the film as etaMD, and the refractive index in the transverse direction of the film as etaTD. The angle of visibility is greatly expanded if the laminate of the uniaxially stretched film formed of the film and the high-polymer having the positive specific double refraction value is incorporated into the liquid crystal display device.

Abstract: PURPOSE:To prevent fluctuation and aging of speed change performance, by regulating the working pressure such that an actual speed change time coincides with a preset referential value. CONSTITUTION:When speed change is made, speed change time (b) is detected by a speed change time detecting means (a) and compared with a referential value (c) in a comparing means (d). Based on the comparison results, a hydraulic pressure correcting means (e) boosts the working pressure if the actual speed change time (b) is longer than the referential value (c), for example, while reduces the working pressure in reverse case by providing a signal to a hydraulic pressure command means (f). Since the working pressure is regulated such that the actual speed change time coincides with a preset value, fluctuation of speed change performance of a transmission is eliminated and aging of the transmission performance can be prevented.

Abstract: PURPOSE:To eliminate the need for the space for an image-to-image gap electrostatic discharging device and to realize compact constitution by equipping an electrophotographic part with an inserting means which puts a beam expanding means on the optical path of a laser beam and an insertion control means which performs image-to-image gap erasure. CONSTITUTION:When the exposure of an image is finished, a control part 5 operates a solenoid 19 at a no-image part to put a slit 18 on the optical path. The laser beam 6 reaches a photosensitive drum 11 through the slit 18 to perform the image-to-image erasure. At this time, the laser beam 6 becomes out of focus on the photosensitive drum through the diffracting operation of the slit 18, namely, increases in beam diameter to reduce an irregularity in the quantity of light, thereby carrying out electrostatic discharging with a small irregularity in erasure. Thus, the laser beam from a laser scanning device is used to perform the image-to-image discharging, so no image-to-image gap discharging lamp is required and the compact laser printer is obtained.
