Abstract: PURPOSE:To eliminate the need for a line changeover device and to attain changeover of an active and a standby system even in the unit of lines by controlling whether a communication line is connected to a communication controller or disconnected from the communication controller based on a connection interruption display data. CONSTITUTION:Suppose that a switching command signal of a switching command area 65-2A read simultaneously is set, when a line controller 52A reads a line relevant memory area 65-0A. A data control section 67A clears a transmission reception control command signal SRC regardless of the content of other areas of a line memory 65A. Then a switching data from a changeover data area 65-1A is sent to a data line DL. In this case, since the switching command is set in this case, a gate G4A is active and a switching data is set to a changeover control section 74 via the line DL. Similarly, a gate G4B is set and the switching data from a device 52B is set to the control section 74. The control section 74 commands the execution of connection/interruption to/from a communication line and changeover of a system A/B or the like to a line changeover section 75 according to the predetermined switching logic based on the set switching data of the systems A/B.

IPC: G03B21/62
Filed: 1988-11-22
Abstract: PURPOSE:To improve the resolution of image light by arranging a sheet which has a Fresnel lens on a light incident side, disposing a sheet which diffuses light on a light emitting side and providing a diffusion layer part which prevents the resolution of the image light from being deteriorated caused by multiple diffusion on this light diffusion sheet, besides. CONSTITUTION:An image on the tube surface of a CRT 12 is magnified and projected by a projection lens 13 and the image is formed on a screen 16 through reflecting mirrors 14 and 15. The image light is image-formed on a double lenticular lens sheet 16b after it is converged by the Fresnel lens sheet 16a. Then, since the diffusion layer 17 is formed exceedingly thin on the surface of the light incident side of the sheet 16b, the formed image is not multiple- diffused. As the result, it does not become a multiple image and a clear image is obtained. Besides, the angle of visual field in the right and left directions of the screen is made constant by the constitution of the double lenticular lens.

Title: Switching circuit
Inventor: YOKOO HIDETOSHI
IPC: H03K17/08
Filed: 1989-11-14
Abstract: PURPOSE:To reduce heat dissipation from transistors(TRs) and resistors by operating the circuit as Darlington connection with a rush current arisen and the circuit as single TR connection at a steady-state current. CONSTITUTION:When a TR Q1 is in unsaturated state, part of a current of a load L passes through a diode D1 and a base current for the TR Q1 is supplied through a base-emitter connection of a TR Q2, then the TR Q1 reaches a saturat ing state. Thus, the base-emitter voltage of the TR Q1 is suppressed, That is, when a rush current flows to the load L, the circuit acts like a Darlington TR operated with a few base current and when the current reaches its steady- state, the circuit acts like a single TR thereby lowering the emitter-collector voltage of the TR Q1. Thus, heat dissipation of the output TR Q1 and of the base resistor R1 of the TR Q1 is reduced.
