Title: Rear projection type screen and rear projector
Inventor: YAMAGUCHI HIROSHI
IPC: G03B21/625
Filed: 1998-09-08
Abstract: PROBLEM TO BE SOLVED: To provide a rear projection type screen and a rear projector whose transmitted light loss is small and whose reduction effect of external light reflection is large. SOLUTION: A Fresnel lens sheet 4, a lenticular lens array sheet 5 whose perpendicular direction is set as a longitudinal direction and a light diffusing plate 7 are arranged from a projection side. The light diffusing plate 7 possesses louver-like light absorbing wall lines 8 arrayed so as to set a horizontal direction as the longitudinal direction and a light diffusing layer 9, and the light diffusing layer 9 is arranged on an observing side from the light absorbing wall lines 8. Projected light is appropriately diffused and emitted without causing an absorption loss by the light absorbing wall column 8. External light made incident from the observing side is absorbed by the light absorbing wall lines 8 after being diffused by the light diffusing layer 9. Also, a total reflection component on a lenticular lens surface is absorbed by the light absorbing wall lines 8.  Thus, the deterioration of contrast by diffusing reflection is remarkably reduced.

Filed: 1997-08-14
Abstract: PROBLEM TO BE SOLVED: To suppress generation of flaw, contamination, or the like, by additionally providing an oxidation process employing an oxidizing agent as a principle component after provision of a catalyst or activation in a plating process of an easy-to-plate resin where the easy-to-plate resin is subjected to two color molding such that it can be exposed in an arbitrary shape. SOLUTION: A primary molding 3 of ABS resin having a substantially T-shaped protrusion is produced and then a secondary molding 2 of second resin PET is produced by two color molding such that the substantially T-shaped protrusion is exposed by a PET resin with other part being wrapped. The two color molding is subjected to plating through standard plating process for ABS and an oxidation process employing an oxidizing agent as a principle component is employed additionally. Since a catalyst adhering to the surface of resin is inactivated or removed by the oxidizing agent, the catalyst adhering onto the easy-to-plate resin, i.e., ABS, 15 left and the catalyst on a plate retardant resin, i.e., the PET, is removed. Thus, generation of flaw, contamination, or the like, can be suppressed.

Abstract: PURPOSE:To enable camera-shake correction dealing with a slow camera-shake to a fast camera-shake at the time of photographing by detecting the shake of a photographic optical axis and driving a correction optical system by the output of an integrating circuit when an integration constant is changed. CONSTITUTION:The integration coefft. of the integrating circuit 23 is set on a small size and the low-frequency components, including DC components, such as null voltage, are rapidly removed when a main power source switch of a camera is turned on. A moving piece 26 switches to a large resistor R2 side for integration and the integration constant of the integrating circuit 23 changes to a large side when a photometric switch 33 is turned on in this state. The output of an angular velocity sensor 21, of which the band pass is set down to a low frequency region, and the output from which the DC components, such as null voltage, are removed are then amplified by a differential amplifier 22. The angular velocity signal adequately reflecting the output of the angular velocity sensor 21 is inputted to the integrating circuit 29 which converts the camera-shake at the time of pushing a release button to an angular displacement quantity and outputs this quantity. Correction motors 15, 16 are driven in accordance with this output and the output of an MR sensor 18, by which the camera-shake is corrected.
