摘要： In an optical encoder comprising an optical scale in which a light transmission portion and a light non-transparent portion are arranged and an output pattern obtained by emitting an incident light functions as an optical code, a light source portion and a light detecting portion, the light non-transparent portion is constituted of at least one pair of inclined surfaces which are opposed in such a manner as to become farther away from each other towards the side where the incident light enters and set so that an incident angle of the optical axis of the incident light from the light source should not be smaller than a critical angle of incidence, and the light non-transparent portion is constructed so that the incident light which enters one inclined surface should be totally reflected thereon to enter the other inclined surface and then at least part of the incident light should be reflected on the other inclined surface, and a reflected light which is reflected on the other inclined surface should not enter a light emitting portion of the light source and a reflecting portion around the light emitting portion.

摘要： A scale generates a periodic light-intensity distribution pattern having a pitch upon irradiation by emission light from a light source. Light-detecting element groups are shifted relative to the scale to generate phase signals having fixed phase differences. Light-detecting elements are adjacently positioned to have the same phase to form each light-detecting element group. Area centers of gravity on a phase axis of the light-detecting element groups having a fixed phase difference are made coincident with each other.

摘要： A liquid crystal light valve has a photoconductive layer between a pair of electrodes, and a liquid crystal layer. The resistivity of the photoconductive layer at the portion which is irradiated with light is reduced by partial light irradiation. By applying a voltage between the electrodes in this state, the voltage is applied to the liquid crystal layer in the portion which is irradiated with light and the crystalline structure at this portion is changed, thereby enabling image data writing. The photoconductive layer is a laminate of an amorphous Si film and an inorganic insulating film disposed on the electrode side, which structure suppresses the carrier injection from the electrode to the amorphous Si film. The polarity of a voltage for writing image data into the liquid crystal light valve is inverted for every horizontal scanning operation. That is, writing of black portions on a white background and writing of white portions on a black background are alternately executed. It is therefore possible to write data on one line and erase the data on the next line by a voltage of one polarity. By periodically setting a period in which no voltage is applied during writing, writing error caused by stored charges is prevented.
摘要翻译：液晶光阀在一对电极和液晶层之间具有光电导层。通过部分光照射，光照射部分的光电导层的电阻率降低。通过在这种状态下在电极之间施加电压，将电压施加到被照射的部分中的液晶层，并且该部分的晶体结构发生变化，从而使图像数据写入。光电导层是设置在电极侧的非晶Si膜和无机绝缘膜的层叠体，该结构抑制从电极向非晶Si膜的载流子注入。对于每次水平扫描操作，将图像数据写入液晶光阀的电压的极性反转。也就是说，交替地执行在白色背景上写入黑色部分并在黑色背景上写入白色部分。因此，可以在一行上写入数据，并通过一个极性的电压擦除下一行的数据。通过周期性地设定在写入期间不施加电压的周期，防止由存储的电荷引起的写入错误。

摘要： A large-size screen display apparatus, having a plurality of projection display devices arrayed in a matrix arrangement to form one large screen, is for displaying characters and the like. A screen of each projection display device consists of a transparent plate disposed on the light entrance side and a diffusing surface disposed on the viewing side. Further, and the periphery of the transparent plate is mounted to a housing of the display apparatus. Light rays emanated from a projection lens are reflected by the transparent plate, whereby an optical image is formed on the entire diffusing screen. Since the optical image is displayed on the entire surface of the diffusing screen, no non-display areas will appear on the screen even when the plurality of projection display device are arranged in the matrix array.
