Patent JP-S6145230-A (JP)
Title: Optical switch
Inventor: NAKAMURA HITOSHI
IPC: G02F1/015
Filed: 1984-08-10
Abstract: PURPOSE:To obtain superior switching characteristics such as power consumption, a quenching ratio, and insertion loss by employing bottleneck structure in which a carrier injected into an optical branching part does not spread as the structure of a carrier injection type switch. CONSTITUTION:The top surface drawing of a 1X2Y reflection optical switch is expanded to show a path of light, and light incident from an incidence port 31 reaches a part 25 where there is variation in refractive index due to carrier injection. When no carrier is injected and the refractive index therefore has no variation, the majority of the incident light is projected from a projection port I 32 through the path 36 and leak light is projected from a projection port II33. When a carrier is injected, the refractive index of said port 25 decreases, the incident light is refleted there and passes through a path 35, and the majority of the light is projected from a projection port II33. Namely, the path of the light is switches from the projection port I 32 to II33. Consequently, the ratio of the projected light and leak light is the quenching ratio, which is improved greatly.

Title: Picture tube
Inventor: KIMURA MASAMICHI
IPC: H01J29/86
Filed: 1984-08-09
Abstract: PURPOSE:To produce easily readable regenerative images on a vertical picture screen without deteriorating the structural strength or increasing the cost of the glass bulb by specifying the relationship between the diagonal length, the vertical curvature radius and the horizontal curvature radius of the outer surface of the front wall. CONSTITUTION:The picture tube of this invention has a front wall 2 the horizontal outer diameter of which is smaller than the vertical outer diameter. The diagonal length (l), the vertical curvature radius (a) and the horizontal curvature radius (d) of the outer surface of the front wall 2 are adjusted according to the formula 8l>=a>=2b. When the vertical curvature radius (a) is adjusted to be larger than the horizontal curvature radius (b) of a conventional level according to the above formula, there is only little distance between the central area of the front wall 2 and its right and left sides because the horizontal diameter of the front wall 2 is relatively small. Therefore, a rectangular picture screen consisting of a phosphor screen formed on the inner surface of the front wall 2 appears to be flat. Furthermore, there is no possibility that light emitted from an illumination lamp installed near the ceiling is reflected by the front wall 2 and enters the eyes.
