Title: Rear projection device
Inventor: TAKEDA YASUHIKO
IPC: H04N5/74
Filed: 1994-09-28
Abstract: PURPOSE: To make the spacings between effective screens approximately zero (seamless) so as to impart a continuous feel to these screens and to provide powerful videos and enhanced appealing power by varying the directions of the planes of polarization of paired polarizing filters by each of the adjacent pairs. CONSTITUTION: Projectors 1, 7, 13 are provided with the polarizing filters 3, 9, 15 on their front surfaces. The screens 5, 11, 17 formed to make pairs are provided with the polarizing filters having the directions of the planes of polarization approximately the same as the directions of the planes of polarization of the polarizing filters at any of the front polarizing filters or rear polarizing filters or the inside of these screens to make a pair. This pair consists of a plurality and is so constituted that the directions of the planes of polarization of the paired polarizing filters vary with each of the adjacent pairs and that the adjacent pairs are intersected approximately orthogonally with each other. The light rays emitted from the projectors 1, 7, 13 pass only the screens formed to make the pair and do not pass the adjacent screens any more.  The need for forming the joints to prevent the crossinterference of the light rays between the adjacent screens is thus eliminated. Then, the adjacent screens continue with zero clearances and the interruption by the joints of the videos is prevented.

Inventor: OSAWA YASUO
IPC: B60C15/024
Filed: 1992-08-07
Abstract: PURPOSE:To sufficiently improve proofing of a tire against slipping off of a rim and/or smoothness against a rim without making the tire and rim assembly work difficult. CONSTITUTION:A shape, which is similar to a circular arc shaped protrusion made when a bead portion 23 is pressed outward with a uniform pressure, is turned reversely and a recessed groove 38 is formed on a bead base part 36. Thus, when the bead base part 36 is so deformed as to overlap on one circular cone surface (outside surface of a rim) by virtue of equipping it to a rim, the contact pressure between the bead base part 36 and the outside surface of the rim becomes so uniform that sliding of the tire 21 in the shaft direction or in the circumference direction may be strongly restrained.

The concn. of the carbon dioxide is displayed in a display part 5. The size and weight are reduced in this way and the carrying of the sensor is facilitated. In addition, the calibration is easily made even if the standard gas is not used. The exact measured value is thus obtd.

Title: Method for injection molding of plastic molded article with partly thin part and mold used for injection molding
Inventor: ISHIYAMA HIDEYUKI
IPC: B29C45/73
Filed: 1996-09-05
Abstract: PROBLEM TO BE SOLVED: To prevent weld from being generated on a thin part and to speed up molding cycle by performing molding while development of a skin layer is suppressed when the thin part is molded by using a movable core. SOLUTION: This method for molding is performed in such a way that a movable core 2 is combined in a mold for injection molding of a plastic and just after a resin is filled, this movable core 2 is forwarded to a definite distance and a thin part is molded there. In this case, a cartridge heater 5 and a cooling medium circulation flow path 2a are combined in the movable core 2 and when the movable core is forwarded into the mold, the movable core 2 is heated by driving the cartridge heater 5 to heat the resin of the thin part and when the mold is cooled, a cooling medium is circulated in the cooling medium circulation flow path 2a to cool the thin part. Development of a skin layer can be suppressed by this effect of heating and cooling and as the result, weld is not generated. In addition, by performing forcible cooling, molding cycle can be sped up (shortened).

Abstract: PURPOSE:To always obtain prescribed recording output even when the characteristic of a semiconductor laser changes by providing a level holding circuit, performing feedback control even at the time of recording, and holding recording current just before by the level holding circuit provided newly at the time of reproduction. CONSTITUTION:At the time of switching a mode from a recording state to a reproducing state, a recording current value just before is held by the level holding circuit 8.

Thereby, it is possible to apply power control by the feedback control even in recording in a power control device with slow response. In such a way, it is possible to always obtain the prescribed recording output even when the characteristic of the semiconductor laser 13 changes due to the influence of return light from a medium, temperature change, or deterioration in the lapse of time, etc.
