摘要： An edge image extraction light modulator forms an edge portion image corresponding to a boundary between two optically equalized portions of a liquid crystal layer. Each portion has a different bistable state and an edge portion optically distinct from the two optically equalized portions. An optical image is written onto the light valve while applying a voltage between two transparent electrode layers of the light valve to effect switching between a first stable optical axis and a second stable optical axis. The light valve is illuminated and the edge portion of the written image is read. A first and a second polarizer are in crossed-Nicols position so that the two optically equalized portions comprise a portion having the written image except for the edge portion thereof and a non-written portion. The edge portion is not optically equal to the two optically equal portions and can thus be detected. A method of driving the edge image extraction light modulator includes writing an optical image onto the light valve by irradiating a photoconductive layer with light. A first pulse voltage is applied to erase and reset the light valve, and a second pulse voltage is applied, having a polarity opposite that of the first pulse voltage, to generate carriers diffusing in the photoconductive film to impart an electric field to the liquid crystal layer and form an enlarged image of the optical image in the light valve. A third pulse voltage, having the same polarity as that of the first pulse voltage, erases a part of the enlarged image except for an edge portion thereof to form an edge enhanced image in the light valve.

摘要： The present invention is concerned with point/output characteristics of a light input image having density gradation using a light writing type light valve comprising a combination of a hydrogenated amorphous silicon photoconductor and a ferroelectric liquid crystal. More specifically, the invention relates to a method of expressing continuous gradation using a light writing type ferroelectric liquid crystal light valve that has been difficult to realize. The expression of continuous gradation is made possible by superposing a DC bias voltage of from 0.1 V to 10 V on a rectangular-wave voltage or a bipolar pulse voltage that has theretofore been used as a driving voltage in order to strongly couple together the spontaneous polarization of ferroelectric liquid crystal and the polarity of the DC voltage, and by eliminating the bistability exhibited by the ferroelectric liquid crystal while developing a monostable condition.

摘要： An object of the invention is to provide a method of introducing sightly tilting homeotropic orientation into a liquid crystal layer by oblique evaporation of inorganic material by one step, and a further object is to apply this method to provide a reliable liquid crystal electro-optical device or a liquid crystal light valve. FIG. 1 shows an example of the method to introduce the slightly tilting homeotropic orientation into the liquid crystal layer by the one step of the oblique evaporation of the inorganic material. The orientation film is formed by the one step oblique evaporation. An incident angle is set from 45.degree. to 70.degree. relative to a parallel direction of the substrate, and a film thickness is set to 20 nm through 500 nm measured during the film deposition by a film thickness gage disposed at a vertical distance equal between the evaporation source and the substrate. The orientation film is used in the liquid crystal electro-optical device or the liquid crystal light valve.

摘要： A liquid crystal light valve cell has two optically different states switchable therebetween by a bias voltage in response to incident light. A ferroelectric liquid crystal layer is sandwiched by a pair of front and rear alignment layers to establish the two bistable states in the ferroelectric liquid crystal layer. A front electrode layer is disposed on the front alignment layer. An optically reflecting layer is disposed on the rear alignment layer. A photo-conductive layer is disposed on the reflecting layer and responsive to the incident light incident from the rear face of cell to increase its electroconductivity. A rear electrode layer is disposed on the photo-conductive layer in cooperation with the front electrode layer to apply the bias voltage between the multi-layer structure including the liquid crystal layer and the photo-conductive layer such that effective bias voltage is applied across the liquid crystal layer through the increased electroconductive region of photo-conductive layer to thereby effect the switching between the two bistable states. The multi-layer structure is sandwiched by a pair of front and rear transparent substrates to construct the liquid crystal light valve cell.

摘要： An aqueous dispersion-type acrylic pressure-sensitive adhesive composition includes acrylic copolymer emulsion particles dispersed in an aqueous medium. The acrylic copolymer emulsion particles has a ratio (ANIN)/(ANSUR) of 1 or more, wherein (ANIN) is an amount of acid groups in the acrylic copolymer emulsion particles, and (ANSUR) is an amount of acid groups on the surfaces of the acrylic copolymer emulsion particles, (ANIN) and (ANSUR) being calculated from a titration curve of potentiometric titration performed by adding an inorganic base solution to an acidic sample dispersion solution containing the acrylic copolymer emulsion particles dispersed in ion exchange water. A pressure-sensitive adhesive tape which strongly adheres to an adherend and has excellent removability can be formed using the aqueous dispersion-type acrylic pressure-sensitive adhesive composition.
