Title: Diffusion plate, illumination device and liquid crystal display
Inventor: MIYAMOTO TAKESHI
IPC: G02F1/13357
Filed: 1996-08-28
Abstract: PROBLEM TO BE SOLVED: To make it possible to efficiently utilize the light from a light source by allowing the particles formed by coating the surfaces of pearl gloss pigments with polymers to exist in uniform dispersion at a diffusion plate. SOLUTION: The particles 11 formed by coating the surfaces of mica 10 with titanium dioxide 12 and coating the surfaces of the titanium dioxide 12 with the polymers 15 exist in uniform dispersion on the diffusion plate 34. Even if the particles 11 exist at the diffusion plate 34 constituted in such a manner in the state of maintaining contact therewith, the spacings of at least twice the thickness of the polymer layers are eventually generated between the pearl gloss pigments and the pearl gloss pigments by the polymers 15 with which the pearl gloss pigments are coated. Incident light 14, therefore, passes the polymers 15 and can pass, as scattered light, the diffusion plate 34 even if the particles 11 exist in the state of maintaining the contact. As a result, the loss of the incident light 14 is made smaller in comparison with the nonmodified pearl gloss pigments.

Filed: 1985-11-05
Abstract: PURPOSE:To obtain a cooling device for a rotary body in a vacuum with a high heat-removing efficiency for objects to cool in a vacuum and with an ability of producing vacuum, by feeding a coolant to the object to cool and forming a jet spray of the fed coolant. CONSTITUTION:An evaporated coolant 4 is spouted through a gap between a target 3 and a nozzle 7 in the direction of the arrows. Since the gap is made smaller compared with the heat exchange portion of the target 3 and the coolant 4, the gaseous coolant 4 makes a jet spray. Because the peripheries of the target 3 and the nozzle 7 are all faced downward, the coolant 4 is spouted as a jet spray downward obliquely, depressing the residual gas in the vacuum container 1 until it strikes to the side wall of the vacuum container 1, to raise the degree of vacuum around the target 3. The vapor is liquefied after striking to the side wall of the vacuum container 1, drops along the side wall, and is screwed up by a screw 8, repeating such a process. On the other hand, the residual gas depressed downward is confined and kept at the bottom of the side wall, raising the degree of vacuum around the target 3.
