Title: Programmable controller
Inventor: KATAGISHI YUKIO
IPC: G05B19/05
Filed: 1988-11-28
Abstract: PURPOSE:To facilitate the detection of the abnormal areas, the maintenance/ inspection, and the degub when the execution of a program is delayed by setting again both the user program data and the input data which are under execution just by switching a mode changeover switch at a buffer. CONSTITUTION:A mode process means 30 decides whether a mode changeover switch 7 is kept at the program side or the monitor side and sets a flag at the decided side as long as an operation switch 8 is kept turned on. A display data production means 50 decides whether the flag is set at the program or monitor side by the means 30 while the switch 8 is kept turned on. If the flag is set at the program side, the program data under execution is set at a display buffer 12. In this case, the program data on a program unit storing the unit No. is set at a display instruction register 13. While the input data received from a device 10 to be controlled under execution is set at the buffer 12 in case the flag is set at the monitor side. A display control means 60 displays the data set at the buffer 12 at a display part 5.

Filed: 1987-11-26
Abstract: PURPOSE:To attain impedance matching with a next level and to make a power source one by reducing the output impedance of an element in which an operation current is small and the output impedance is large through the use of two resistances which are connected in serial and a capacitor connected between both resistances and an earth. CONSTITUTION:FETs 1 and 2 are cascade-connected. The operation current of FET1 is smaller than that of FET2, and the output impedance of FET1 is larger than that of FET2. A drain voltage is supplied to FET1 by a voltage supply circuit consisting of the resistances 21 and 20 and the capacitor 22 connected between both resistances and the earth. Since a voltage drop in the resistances 21 and 20 becomes equal to that in a resistance 10 connected to FET2, and voltage supply for both FETs can be executed by single power source, whereby the output impedance of FET1 can be reduced by said voltage supply circuit, impedance matching between both FETs is attained.

Abstract: PURPOSE:To uniformize the luminance by using a fluorescent dye in a light guide having a flat section. CONSTITUTION:A light guide 21 has a flat section and an organic fluorescent dye 25 is uniformly mixed throughout the light guide 21. An optical fiber 31 is formed where a core material 16 which is extended in the direction perpendicular to the surface of paper and has an elliptic section is coated with a clad material 17, and the fluorescent dye 25 is uniformly mixed throughout the core material 16, and then, the light incident on one end of the core material 16 is reflected on not only the clad material 17 but also the fluorescent dye 25 and is emitted to the outside from the other end of the core material 16. In another example, a radius r1 or curvature of bend in the exit side of the meandering optical fiber 31 is set to a value smaller than the critical angle of the fiber 31, and the opposite side is bent with a larger radius r2 so that the light is not emitted. A high-refractive index material 32 is stuck like a convex lens to one side face of the optical fiber 31 from which the clad material 17 is selectively peeled, and the light is emitted out of the fiber from this side face. Thus, the luminance of the exit light is uniformized throughout the light guide.
