Title: Transmission type liquid crystal display device
Inventor: SONEHARA TOMIO
IPC: G02B6/00
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To save the energy of a backlight source and to improve visibility of a liquid crystal display element in the viewing angle direction by controlling the distribution of luminous intensity characteristics of light emitted from a flat light source for backlight illumination to be almost coincident with the viewing angle characteristics of a liquid crystal display element as a modulating means for light. SOLUTION: This device consists of a liquid crystal display element holding a liquid crystal between a pair of substrates and a light source for illumination disposed on the back side of the liquid crystal display element. The illumination light source consists of a light emitting body and a light guide in which the light from the light emitting body enters through the side face and outgoes to the liquid crystal display element direction. The light emitted from the light guide shows distribution characteristics with the peak in a specified direction by the light guide. The peak of the distribution characteristics is controlled to be almost coincident with the center of the viewing angle characteristics of the liquid crystal display element.  The figure shows the distribution of luminous intensity characteristics 6 of light in the system (shown as a broken line) and the viewing angle region 7 (shown as arrows) to give >=5 contrast of the liquid crystal display element.

Title: Image preservative stabilizer for thermosensitive recording paper
Inventor: YAMAMOTO NOBUYUKI
IPC: B41M5/337
Filed: 1988-03-30
Abstract: PURPOSE:To eliminate occurrence of texture fog and restrict the extinction of a recorded image by adding specific substituted bisphenol compounds to the thermosensitive coloring layer of thermosensitive recording paper. CONSTITUTION:Thermosensitive recording paper contains added substituted bisphenol compound shown by formula I. This compound eliminates generation of texture fog and restricts the discharge of a recorded image due to humidity or heat as superior properties. Furthermore, this compound can be industrially manufactured in a simple manner. It is easily obtained by allowing substituted phenols and ketonic acids such as glyoxylic acid and pyruvic acid to undergo reaction process in the presence of acid catalysts to obtain acids of substituted bisphenol compounds and further perform esterification of the acids. To manufacture thermosensitive recording paper, this preservative stabilizer is added to an aqueous dispersion liquid containing a coloring material which forms color at the time of heating, a developer and a binder, and this preparation is applied to base paper.

Abstract: PURPOSE:To make distribution of light bidirectionally among four pieces of optical fibers possible by using a square columnar reflecting mirror. CONSTITUTION:The light transmitted through an optical fiber 12 spreads in a pi/2 cut cylindrical focusing lens 16, and emits from an outlet end faces as parallel rays.

The reflected rays respectively direct toward pi/2 cut cylindrical focusing lenses 15, 17. The remaining one third of the parallel rays does not fall onto the mirror 19, passes by each one sixth through both sides of the reflecting mirror and is made incident to the end face of a pi/2 cut cylindrical focusing lens 18 opposite thereto. Hence, the light propagating in the fiber 12 is distributed uniformly to optical fibers 11, 13, 14.

Abstract: PURPOSE:To prevent a ghost image from being generated on a recording medium, and to obtain a recording image having a high quality by shifting and placing a cylindrical lens in the direction vertical to the scanning direction of a light beam so that an optical axis of the cylindrical lens is not overlapped on an optical axis of other lens which has been placed on the incident side of the lens. CONSTITUTION:An optical axis of the second cylindrical lens 6 is placed by shifting it by a distance L in the direction vertical to the scanning direction of a light beam so that it is not overlapped on an optical axis of a light beam which is scanned by a rotary polyhedral mirror 4 and made incident on the second cylindrical lens 6. Accordingly, the incident surface of the second cylindrical lens 6 is inclined against the incident direction of the light beam, and a reflected light beam thereby is not returned to the rotary polyhedral mirror 4. In this way, the generation of a ghost image due to a rescan by the rotary polyhedral mirror 4 can be prevented, and a recording image having a high quality can be obtained. Also, a distortion caused by an aberration as in case the optical axis of the second cylindrical lens 6 has been inclined is not generated, and the adjustment can also be easily executed.

A control information setting means M5 writes the initial value used in comparison in the non-volatile memory M1 so as to set it when restoration flag information is not restored yet and also the comparing means M14 judges non-coincidence. A restoration flag information setting means M6 executes setting as the restored one in the non-volatile memory M1 when restoration flag information is not restored yet.
