Title: Projection type display device
Inventor: MASUBUCHI SADAO
IPC: G03B21/00
Filed: 1984-10-09
Abstract: PURPOSE:To perform projection in a light room by arranging polarizing plates in front of a screen and noise light so that the transmission axes of the polarizing plates cross each other nearly at right angles and the polarization direction of projection light is nearly parallel to the transmission axis of the polarizing plate in front of the screen. CONSTITUTION:Light projected from in front of the screen 1 is transmitted through the before-screen polarizing plate 2 which has the transmission axis nearly in parallel to the polarization direction of projection light without large attenuation to form an image on the screen surface, and the light is reflected to reach an observer 7. On the other hand, the noise light emitted by the noise light generator 4 consisting of a noise light generation source 5 such as a window and the before-noise-light polarizing plate 6 which transmits only polarized light crossing the transmission axis of the polarizing plate 2 nearly at right angles is attenuated greatly by the polarizing plate 2, so the quantity of light reaching the screen surface is reduced greatly. Consequently, the brightness of a display image on the surface of the screen 1 becomes larger than that of the noise light, so projection in a light room becomes possible.

IPC: B29C39/12
Filed: 1987-08-25
Abstract: PURPOSE:To mold a turn table having uniform thickness, by molding at first a base part of the turn table and then molding a disc part thereon. CONSTITUTION:At first, a top force 6 and a bottom force 7 are brought into tight contact and a base part 9 of a turn table 8 is molded by pouring a molten synthetic resin into a space thereby formed and cooling and solidified it. Then, the top force 6 is taken off and the second top force 10 is set on the base part 9 and is brought into tight contact with the bottom force 7. A ring-shaped space is thereby formed between a ring-shaped groove 11 and the upper face of the outer circumferential part of the base part 9. A ring-shaped disc supporting part 12 of the turn table 8 is formed on the base part 9 by pouring therein a molten synthetic resin. When the thickness of the base part 9 is small, the thickness of the disc supporting part 12 accordingly becomes large and when the thickness of the base part 9 is large, the thickness of the disc supporting part 12 accordingly becomes small. The disc surface becomes thereby sufficiently flat.

IPC: B41M5/382
Filed: 1990-08-10
Abstract: PURPOSE:To obtain a co-winding thermal transfer sheet excellent in both of adhesiveness and releasability, imparting a printing image having resolving power and generating no background staining by forming an adhesive layer from pressure-sensitive adhesive particles having low glass transition temp., resin particles having high glass transition temp. and transferrable wax particles. CONSTITUTION:A thermal transfer sheet A and a material B to be transferred are constituted so as to be temporarily bonded by an adhesive layer C and the adhesive layer consists of pressure-sensitive adhesive particles having low glass transition temp., resin particles having high glass transition temp. and wax particles. The adhesive strength of the adhesive layer is pref. within a range of 300 - 1500g when the adhesive strength of a cut-off sample is measured. When the adhesive strength is below this range, the adhesive strength of the thermal transfer sheet and the material to be transferred is two low and both of them are easy to release and the thermal transfer sheet is easily creased with wrinkles. When the adhesive strength exceeds said range, adhesive strength is sufficient but an ink layer is easily transferred to the material to be transferred even in an unprinted part and the contamination of the material to be transferred is generated.

Abstract: PURPOSE:To feed metal powder into a powder reservoir under stable conditions not affected by the humidity of the open air and to produce a beltlike green compact having high homogeneity and satisfying required characteristics by controlling the atmosphere of the powder housing space in a device for feeding powder for rolling. CONSTITUTION:When metal powder 50 is fed into a powder reservoir 30 formed between a pair of rolling rolls 10, 20, a freely liftable lid 70 is fitted to a feeding device 40 housing the metal powder 50 to be fed and the top of the powder housing space 45 is blocked.

Abstract: PURPOSE:To make protection and rust prevention of steel products in an inorg. material easy by coating and impregnating an aq. inorg. salt soln. having a rust preventive effect on and in the surface of the inorg. material contg. the steel products, then coating a silicone primer on the surface thereof. CONSTITUTION:An aq. soln. of the inorg. salt having the rust preventive effect to steel product is coated on and impregnated into the surface of the inorg. material (e.g., concrete) contg. the steel products. Calcium nitrite, etc. is used for the inorg. salt and the coated amt. thereof is made about 3-30%. Since the rust preventive agent is strongly alkaline, the atmosphere in the concrete, etc., in which neutralization is progressed is returned to the strong alkalinity by coating and impregnating such rust preventive agent. The primer of the silicone or/and silane is then coated on the surface of the inorg. material. The chlorine ions in the inorg. material enclosing the steel products is thereby easily made pollution-free and the protection and rust prevention of the steel products are executed.

Filed: 1990-08-10
Abstract: PURPOSE:To improve brightness and to uniformize the intensity distribution of transmitted light all over the surface of a display part by forming the reflection surface of a side plate in a mirror surface. CONSTITUTION:The side plates 64 of a reflection part 60 are arranged on both sides of a light source 12 so that their reflection surface 70 may be nearly orthogonally crossed with the plate surface of a light diffusing plate 16 and formed in the mirror surface. Therefore, the light source 12 is reflected on the side plates 64 on both sides and a state becomes the same as the state where light sources are arranged on both sides of the light source 12. Therefore, the brightness in both ends of the display part 30 becomes the sum of the brightness from the original light source 12 and the brightness from the virtual light source reflected on the side plates 64 of the reflection part 66. Thus, the brightness is improved and the intensity distribution(light distribution) of the transmitted light becomes nearly uniform all over the surface of the display part 30.

Abstract: PURPOSE:To obtain a picture signal with less noises by controlling each photodetector on and off in accordance with moving of a scan point so that among respective photodetector at least the one farthest from the scan point can be turned off and at least the one nearest to the scan point can be turned on. CONSTITUTION:When a scan point G lies within a range H1, photomultipliers 91 and 92 are turned on, while others 93 and 94 are turned off. When the scan point G lies within a range H2 which covers the middle point of a light condensing guide piece 82 and that of a light condensing guide piece 83, the photomultipliers 92 and 93 are turned on and the others 91 and 94 are turned off. The photomultipliers are controlled in accordance with moving of the scan point G such that the photomultipliers 93 and 94 are turned on and the others 91 and 92 are turned off when the scan point G lies within a range H3. The accelerated phosphorescent light emitted from the scan point G is practically detected by the photomultiplier in the range near to the scan point G, whereas the photomultiplier far away from the scan point G by some distance hardly detects said light.
