Abstract: PROBLEM TO BE SOLVED: To obtain all of a light display, high energy efficiency, and long battery life by arranging a light absorption part on the reverse surface side of a lower substrate and a light emission source on an end surface side of the liquid crystal display device. SOLUTION: This device is equipped with transparent electrodes 16 and 17 formed on the opposite surfaces of upper and lower substrates 20 and 21 and a light scatter type liquid crystal layer 22. The light absorption part 23 is arranged on the reverse surface side of the lower substrate 21 across an air layer and equipped with the light emission source 24 and a lamp reflector 25 which are arranged at the end part of the liquid crystal display body. In an area 18 where no voltage is applied, the liquid crystal layer 22 is in a white turbid state to scatter incident light source 28 by the liquid crystal layer 22 and part of the scattered light reaches the light absorption part 23 below it and absorbed while the rest of the light is scattered upward to present a white outward appearance. In a voltage- applied area 19, on the other hand, a black outward appearance is presented. In the night, etc., the light emitted by the light emission source 24 reaches the white turbid liquid crystal layer in the voltage non-application area 18 to become scattered light; and part of the light is absorbed by the lower light absorption part 23 and the rest is scattered upward, so that although an observer sees white glitter from above, almost no light exits from the voltage non-application area 19.

Abstract: PROBLEM TO BE SOLVED: To provide a front-mounted surface lighting device which is high in visibility in both a lighting ON and a light OFF state. SOLUTION: A light guide plate 1 which has unevenness 12 is arranged on the reflected and projection light surface side of a flat plate and a light source 2 is arranged on its end surface. A lighting device of this constitution is mounted in front of a lit body and has a function which projects a light beam on the lit body and transmits the light beam reflected by the lit body nearly without dispersing it. When lighting is OFF, external light and a light beam emitted by reflecting the external light by the lit body are transmitted nearly without being dispersed.

Abstract: PROBLEM TO BE SOLVED: To obtain, comparatively simply and at low costs, a sliding component, for a watch, whose lubricative performance is excellent and whose lubricative performance can be held for a long period. SOLUTION: A coating treatment by which a thiol compound is stuck is executed to a rotor 4, at a motor 1, and a bearing body (composed of a base plate 5 and of a wheel train receiver 6) which supports the rotor 4 as sliding components at an electronic watch. An -R group at the thiol compound is directed to the outer face while an -SH group is directed to the face of the sliding component. Consequently, when the surface energy of the -R group is lowered, the apparent surface energy of the sliding components becomes low so as to be easily slidable. Since the thiol compound is formed on the whole face in a close state, an ultralow surface energy face is formed, and its coefficient of friction can be made extremely low. In a treatment method, the sliding components are immersed in a solution in which the thiol compound is dissolved.

Abstract: PROBLEM TO BE SOLVED: To guide the light from the rear of a fluorescent tube to a light guide plate by forming a reflecting mirror with reflecting surfaces having a cross sectional shape of a flattened involute curve and reflecting surfaces connected to expand the opening section of the reflecting mirror. SOLUTION: A reflecting mirror 11 is formed with reflecting surfaces 11a1, 11a2 and reflecting surfaces 11b1, 11b2. The reflecting surface 11b1 and the reflecting surface 11a1 are symmetrical with respect to the xz-plane, and the reflecting surface 11b2 and the reflecting surface 11a2, are symmetrical with respect to the xz-plane. The reflecting surface 11a1 is in the range that (x) is larger than the x-coordinate xc of a connection point Ca, i.e., x>=xc, and its shape is shown by the locus of x=(r)×cosθ+f(θ)×(r)×θ×sinθ, y=(r)×sinθ-f(θ)×(r)×θ×cosθ. The reflecting mirror 11 is formed with the reflecting surfaces having such a cross sectional shape and the reflecting surfaces connected to expand the opening section of the reflecting mirror 11, and the light from the rear of a fluorescent tube can be guided to a light guide plate.

Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device with which back light illumination is possible adcording to need, usually with a bright reflection type, an inverter circuit is not needed and the selection of free light emitting colors is possible by arranging a diffusion plate having a light scattering function behind a liquid crystal panel and further, arranging an org. EL surface light emitting body. SOLUTION: The diffusion plate 2 having the light scattering function is arranged behind the liquid crystal panel 1 formed by holding liquid crystals 12 with two sheets of transparent substrates 11 formed with transparent electrodes. The org. EL surface light emitting body 3 formed by laminating transparent electrodes 32, an org. light emitting layer 33 and metallic electrodes 34 on the transparent substrate 31 is arranged behind the diffusion plate 2. This org. EL surface light emitting body 3 may be functioned as a reflection plate at the time of non-energization. The directivity of the reflected light is high and the visibility is poor in the case of the reflection plate having a smooth surface and therefore, the light diffusion plate 2 is necessary. A light diffusion plate which is provided with ruggedness on its surface and is transparent is general as the light diffusion plate 2. The free changing of the light emitting colors is made possible by selecting the org. light emitting materials or combining these materials.

The rear surface of the nozzle plate 2 or the interior of a nozzle is protected by a photoresist and the prepared sol is passed through a 0.5mum-filter to be applied to the surface of the nozzle plate 2 by a dipping method and the coated nozzle plate 2 is heat-treated at 150 deg.C for one hr. A zirconia membrane 21 having many hydroxyl groups is formed in a thickness of about 0.2mum and a fluorine-containing silicone membrane 22 is formed on the zirconia membrane.

Abstract: PURPOSE:To provide the liquid crystal display device having excellent brightness and homogeneity and high visibility and the process for easy production of this device. CONSTITUTION:This liquid crystal display device is constituted by forming a high-refractive index layer 23 consisting of a siloxane macromolecule contg. oxide particulates and a low-refractive index layer 24 consisting of a fluorine contained macromolecule on the surface of parts (glass of a light source, light transmission plate, diffusion plate, liquid crystal panel, cover glass). An excellent reflection attenuating effect is obtd. by adjusting the refractive indices and film thicknesses of the siloxane macromoleculw and fluorine contained macromolecule formed on the surface. The liquid crystal display device is easily produced by applying a sol prepd. by mixing at least the oxide particulates and org. silicon compd. in a solvent and preparing a homogenous soln. on the surface of the parts and further applying a fluorine contained org. compd. soln. thereon, thereby forming two-layered films.

Abstract: PURPOSE:To obtain an ink jet recording head capable of maintaining high printing quality for a long period by applying fluorine-containing silicon coupling agent solution on an oxide fine particle layer, and then heating it to the boiling point or above of the solvent for removing unreacted coupling agent therefrom. CONSTITUTION:When oxide fine particle-dispersed sol is applied on the surface of a nozzle plate 2 and heated, the oxide fine particle layer 21 is fixed firmly. The surface of the oxide fine particle layer 21 is active and has many hydroxyl groups. For this reason, a chemical combination of the fluorine-containing silicon coupling agent 22 can be done with high density. After the completion of the reaction by heating the solvent to boiling point or above, the fluorine-containing silicon coupling agent adhered in an unreaction state is rinsed out and removed with the solvent, so that water and oil-repelling properties become more remarkable.
