Title: Active matrix type liquid crystal display device
Inventor: SAITO HISAFUMI
IPC: G02F1/137
Filed: 1988-12-29
Abstract: PURPOSE:To provide the active matrix type liquid crystal display device which is simple in constitution and with which sufficient illuminance and good display contrast are obtd. by using a guest-host type chiral nematic liquid crystal contg. a black dyestuff as a liquid crystal. CONSTITUTION:The guest-host type chiral nematic liquid crystal layer 28 contg. the black dye is provided between an active matrix substrate 21 arranged with plural picture element electrodes 23 and TFTs 22 in the form of matrix on a transparent electrode substrate 24 and a counter substrate 25 formed with a counter electrode 27 on a transparent insulated substrate 26. Incident light transmits the part of the liquid crystal layer 28 which is on-driven by the applying of voltage from the picture element electrodes 23 and the incident light is absorbed in the off part, by which image display is executed and, therefore, the need for polarizing plates is eliminated and the illuminance is correspondingly improved. The incident light does not arrive to the part of the TFTs 22 and, therefore, the off current decreases in the off state. The on-off ratio of the TFTs is increased in this way and the good display contrast is obtd.

Filed: 1993-12-28
Abstract: PURPOSE:To provide an optical pickup device with satisfactory jitter characteristics by removing the influence of the dead zone of a photo-detector by arranging a hologram element provided with a diffraction grating, of which the basic intervals of gratings are modulated, on one divided side on an optical path. CONSTITUTION:The light emitted from a semiconductor laser 1 is splitted by a line in a direction orthogonal to the track of a medium on the optical axis of a hologram element 2 and becomes zero-order and first-order diffracted light beams by the operation of the diffraction grating of which the intervals of gratings are modulated in the track direction on one side, at least. And, the light beams are made to pass an objective lens 4 and converged to be plural light spots near the recording plane of an information recording medium 5. By this constitution, tracking deviation and focus error signals are obtained by the + or - first-order light of diffracted light flux components, and on the other hand, the non-diffracted zero-order light component can be utilized just for providing a high frequency signal. Therefore, even when a spot diameter is increased/decreased or a spot position is moved, the level of the high frequency output signal is not changed and signals can be detected with satisfactory jitter characteristics.

Title: Optically solidifying molding device
Inventor: NAKANISHI HIDEAKI
IPC: B29K105/24
Filed: 1992-11-20
Abstract: PURPOSE:To provide an optically solidifying molding device equipped with a sweeping member wherein stable performance is maintained and liquid resin on solidified resin can be swept smoothly always to a uniform thickness. CONSTITUTION:A sweeping tool 64 of a sweeper 50 equipped to an optically solidifying molding device 2 in order to sweep a liquid surface 70 of liquid resin 72, is molded by folding a Teflon sheet equipped with flexibility and liquid repellence in a curved shape, and its curved shape part is set at a height so as to enter slightly a liquid surface 70. Therefore, though sweeping is carried out many times, specific elasticity is not missed, and an initial shape can be maintained. Then, stable sweeping performance can be maintained, and reproducibility in height of the liquid surface 70 after sweeping is also excellent. Further, though there is some irregularity on the liquid surface 70, sweeping can be smoothly carried out because of the curved shape. Then, since stuck liquid resin 72 is easy to drop, a trouble wherein an irregularity occurs on the sweeping tool 64 is prevented from occurring by adhesive solidification of the liquid resin 72. Thereby, a three dimensional shape can be molded highly precisely in good reproducibility.

Abstract: PROBLEM TO BE SOLVED: To provide excellent design effect and also a piled body having both damping property and vibrationproof property, etc., together by piling a transparent body and gel-like viscoelastic body one by one and by providing such constitution as making appearance change visible caused by cooperation of deformation of the gel-like viscoelastic body owing to an eternal pressing force with delicate cut of a transparent body. SOLUTION: A piled body K1 is an intermediate element material and practically used by attaching it to the final product in form of something. In this case, a transparent body 1 and silicone gel body 21 are initially in such a state that they make mutual contact at vertex 31a of streak groove like a prism of triangular section with minute cuts 31. Light incident on the minute cuts 31 is refracted and reflected, but at a portion where the silicone gel body 21 makes contact with the vertex 31a, this refraction and reflection are restricted and only this part may be so observed as being fused linearly and stripe patterns seem to the drawn dimly. However, when any external pressing force is applied to the piled body K1, the silicone gel body 21 is deformed and tightly stuck to the minute cut 31. Then, appearance as thick linear stripe patterns comes in vision.
