Title: Liquid crystal display device with optical fiber
Inventor: ONISHI KEITA
IPC: G02B6/00
Filed: 1988-10-25
Abstract: PURPOSE:To sufficiently mix colors even in a short distance and, at the same time, to prevent the occurrence of differences between the colors of the light made incident on an optical fiber and the colors of the light appearing at the outgoing end of the fiber by providing composite picture elements respectively composed of plural picture elements of each color of R, G, and B on the incident ends of optical fibers. CONSTITUTION:Each composite picture element 7 is composed of R, G, and B picture elements 9, 10, and 11 uniformly distributed within the outline 8 of an optical fiber. This composite optical fiber 7 is constituted in such a way that the area ratio of R, G, B included therein is almost the same as the ratio of respective totalized areas of all R, G, B picture elements in the optical fiber even when any part of the optical fiber is segmented with a circle having the area by three picture elements. Light emitted from a light source 5 and passed through the composite picture element is made incident on the optical fiber 4 after the light is adjusted in light quantity and rays of light of three colors are emitted from the outgoing end of the fiber 4 in an arbitrary ratio. Therefore, all colors can be displayed by one optical fiber and, at the same time, a change in color caused by the watching angle or a bend of the fiber can be prevented.

Title: Phase plate and optical pickup
Inventor: NISHI NORIAKI
IPC: G02B5/30
Filed: 1995-09-22
Abstract: PURPOSE: To make it possible to enhance the degree of freedom at the time of optical design by arranging crystals in such a manner that the luminous fluxes having a higher refractive index among the luminous fluxes passing the inside of the crystals have a larger angle formed by the plane perpendicular to the luminous fluxes and an optical axis. CONSTITUTION: The crystals are so arranged that the luminous fluxes having a higher refractive index among the luminous fluxes passing the inside of the crystals have a larger angle formed by the plane perpendicular to the luminous fluxes and the optical axis. Since when the optical path is made longer, the angle formed by a ray direction and an optical axis direction A is made smaller and the distance difference Δn between the major axis and the minor axis can be made smaller, if the optical axis direction A of the rock crystal is made to incline to the plane perpendicular to the main ray L1 in such a manner. Namely, the cut section of an ellipse is gradually approximated to a circle.  However, the incident angle of the incident ray is required to be so set as to be Sin<-1>  NA/n} or larger with respect to the numerical aperture NA and refractive index (n) on the incident side. This setting is the requirement necessary for the optical path length of the luminous fluxes passing the rock crystals to attain a uniform optical path length.

Filed: 1985-11-30
Abstract: PURPOSE:To eliminate the unstable state of a potential due to alpha particles by forming a load with nonlinear impedance in a memory cell which are a couple of inverters equipped with loads and driver transistors (TR) and composed of an FF. CONSTITUTION:Diodes D1 and D2 are connected in parallel to load resistances R1 and R2 and then the V-I characteristic that the load impedance based upon the diode D1 or resistance R2 and diode D2 indicates is nonlinear. Therefore, the potential at a point (a), i.e. voltage applied to the resistance R2 drops be cause of an electron generated by alpha particles to prevent storage from being inverted owing to the bistability of the FF. Namely, the junction dielectric strength of the diode D2 is broken down the moment the voltage drop occurs, and a current path is opened between V1 and (a) to supply a voltage, thereby maintaining the potential at the point (a). Consequently, the unstableness of the potential due to alpha particles which occurs possibly to the storage node of the memory cell is eliminated.
