摘要： PURPOSE:To provide an apparatus which surely and efficiently defoam the inside of through holes-to-be in a plurality of through-hole substrates at the same time, prevent bubbles inside through holes-to-be from being trapped, and form a thin, uniform and proper resist film on the entire surface of through-hole substrates. CONSTITUTION:This apparatus is for forming photosensitive resist films on the inside wall of through holes-to-be and the entire surface of a through-hole substrate 1. The apparatus is provided with a reservoir 2 for photosensitive resist liquid 3, means for lifting/lowering and swinging through-hole substrates. A plurality of fixing plates 5 are upright placed, at an equal interval, in the reservoir, facing to each other. Each through-hole substrate is inserted between fixing plates by the lifting/lowering means, and then swung by a swinging means in the direction of the thickness of through-hole substrate. Subsequently, the substrates are pulled up from between fixing plates by the lifting/lowering means.

摘要： PURPOSE:To enhance stage effects of an indirect lighting system by providing, around a halogen bulb, a reflector having a liquid crystal dimming element on a side of the reflecting surface thereof, and changing over ON-or OFF- operation of a voltage with respect to the liquid crystal dimming element of the reflector by the use of a switch. CONSTITUTION:An indirect lighting system 10 is provided with a halogen bulb 12 as a light source inside a cup-like casing 11. The halogen bulb 12 is turned on or off by a switch 13. The lighting system 10 is further provided around the halogen bulb with a reflector 1 constituted of a liquid crystal dimming element on a side of the reflecting surface thereof, where a switch 14 changes over ON-or OFF-operation of a voltage with respect to the liquid crystal dimming element of the reflector 1. If a voltage is not applied to the element, light incident into the reflector 1 is remarkably diffused by the translucent element 2 and reflected light becomes diffusing reflected light. Meanwhile, if a voltage is applied to the element, light incident into the reflector 1 permeates the element 2 which is transparent so as to be reflected by a base plate 7, where the light is approximately regularly reflected owing to high reflectivity of the base plate 7.

摘要： PURPOSE:To view the outside of a door in a wide field of view by disposing a planar lens on one surface of a liquid crystal dimming element changing between the transparent and opaque conditions with the application and non- application of voltage to constitute a peeping window. CONSTITUTION:A peeping window 2 connected to an electric circuit 4 having a switch 3 is incorporated in a door 1 and composed of a liquid crystal dimming element and planar lens. Further, the liquid crystal element dimming is composed of a transparent conductive film interposed between both surfaces of composite film of a transparent resin and liquid crystal substance to dispose a transparent substrate such as glass or plastic film therein so that the element gets transparent in the application of voltage and opaque in the non-application of voltage.

摘要： PURPOSE:To prevent a color from being left at the time of decoloring by forming electrodes on both surfaces of a specific smectic liquid crystal film, and making at least one of the opposite electrodes transparent. CONSTITUTION:The electrodes 11 are formed on both surfaces of the smectic liquid crystal film consisting of dichroic pigment made of side chain type high molecular liquid crystal wherein a mesogen group is coupled with the side chain of the skeleton chain of a polymer and a low-molecular nematic liquid crystal and at least one of the opposite electrodes 1 is made transparent. This composite liquid film 2 is smectic liquid crystal in a constant temperature range. When an electric field of low frequency is applied, the light transmissivity becomes considerably lower than that before the electric field is applied and the opaqueness increases, but when an electric field of high frequency is applied, the film increases in light transmissivity to come to transparent, and the transparency varies continuously with the frequency of the applied electric field, so that the previous transparency is maintained when the application of electric field is turned off. Consequently, no color is left at the time of decoloring.

摘要： PURPOSE:To allow the writing, displaying, preserving, erasing, and changing of information on characters, graphics, etc., and to prevent the splashing of powder at the time of writing and erasing by inserting a film consisting of a specific material between a lower electrode and a surface transparent electrode. CONSTITUTION:The film of such material which is reversibly changed in the transparent state and the opaque state according to the various levels of the frequencies of impressed electric fields and maintains the transparent or opaque state before the removal in spite of the removal of the impressed electric fields is inserted between the lower electrode 2 and the surface transparent electrode 1 constituted by packing transparent conductors 1b into the many through-holes bored in a transparent insulating film 1a. The transparent insulating film 1a is exemplified by, for example, films, etc., of polyethylene terephthalate, polyvinyl chloride, etc. The transparent conductors 1b are exemplified by conductive high-polymer compds., etc., such as polypyrrole and polythiophene. The writing, displaying, preserving, erasing, and changing of the information on the characters, graphics, etc., are freely executed in this way without splashing the powder.

摘要： PURPOSE:To improve the response of functions and to reduce the size and cost of the whole optical circuit and increase its integration by controlling a switch function and a volume function by using an electric signal. CONSTITUTION:A liquid crystal layer 5 which changes in orientation with an electric signal is put halfway in the waveguide of a core 3, and the quantity of light transmitted through the waveguide is controlled by the change in the orientation of the liquid crystal layer 5. Therefore, the responding speed is much faster than when the quantity of the transmitted light is controlled by a mechanical driving device. Further, the liquid crystal layer 5 is arranged in the optical circuit board 1, so the need to provide a mechanism which controls the quantity of the light propagated in the waveguide outside the optical circuit board 1 separately is eliminated. Consequently, the optical circuit is reduced in size, increased in integration, and reduced in cost.

摘要： PURPOSE:To produce the high-performance light guide at a low cost by previously forming a resin layer of a low refractive index to serve as a clad to core forming parts, subjecting a thermoplastic sheet to thermal press forming to form grooves for cores, the inside surfaces of which are enclosed by the resin layer of the low refractive indexz, and embedding a resin of a high refractive index to serve as cores into the grooves for cores. CONSTITUTION:The resin layer 2 of the low refractive index to serve as the clads is formed on the surface of the thermoplastic sheet 1. The thermoplastic sheet 1 constitutes the substrate (base material) to support the cores 6 to be formed afterward. The thermoplastic sheet 1 (composite sheet 11) is then subjected to hot press forming. The press hot press forming is executed by using metallic molds 3, 4 heated to the softening temp. of the resin of the thermoplastic sheet 1 to form the grooves 5, the inside surfaces of which are enclosed by the clad layers 2. The cores 6 are formed in the formed grooves 5 for cores. The example, a liquid curing type high refractive index resin is cast into the grooves 5 and is cured. The high-performance light guide is produced in this way at a low cost.

摘要： PURPOSE:To improve an optical coupling property by preparing a base plate formed with lenses for optically coupling cores and external optical systems in the positions opposite to the desired end faces of grooves and packing a liquid resin into the grooves. CONSTITUTION:The grooves 21 are formed in desired patterns on the surface of the base plate 2 and the lenses 4 are integrally formed in the positions opposite to the desired end faces 21a of the grooves 21 of the base plate 2. The liquid resin 5 is packed into the grooves 21 and the cores 3 are embedded and formed in the base plate 2 by solidifying the liquid resin 5, by which the optical circuit plate 1 is obtd. The lenses 4 are opposed to the desired end faces 3a of the cores 3 and execute optical coupling of the cores 3 and the external optical system. The need for freshly adding the lenses or making optical registration thereof is thereby eliminated and the optical coupling property is improved.
