Abstract: PURPOSE:To reduce the thickness of the title display panel by applying a voltage to part of a core layer and varying the refractive index of the core layer, and emitting light confined previously to the core layer of an optical waveguide out of the optical waveguide and displaying a graphic form. CONSTITUTION:Light emitted by a light source 7 is varied in intensity by an intensity adjusting device 8, propagated in an optical fiber 6 and made incident on the core layer 3 of the optical waveguide 20, and then confined to the core layer 3. Then when switch circuits 12 and 14 are closed, a voltage is applied to the core layer 3 at the corresponding part to vary the internal polarization rate of the core layer 3, and when the refractive index of the core layer 3 decreases to the refractive indexes or less of clad layers 2 and 4, the light confined to the core layer 3 is transmitted through the clad layer 2 (clad layer 4) and emitted out of the optical waveguide 20; and this light is used to display the graphic form and the main body of the display panel is constituted as the optical waveguide 20 to reduce the thickness of the device.

Filed: 1998-01-22
Abstract: PROBLEM TO BE SOLVED: To improve measurement accuracy and working efficiency by providing a first switch for selecting either of a pair of light-emitting diodes whose conduction directions are opposite to each other, and a second switch for connecting a lead wire for measurement to be connected to a measurement target. SOLUTION: First, a switch 9h is closed and a power supply is connected and then switches 9g and 9f are closed to sides (d) and (b), respectively. Then, since no current flows to power transistors 1-6, light-emitting diodes 9j, 9l, 9n, and 9p do not turn on. Then, when the switches 9g and 9f are closed to sides (c) and (b), respectively, current flows to the power transistors 2-6 and light-emitting diodes 9i, 9k, 9m, and 9o turn on. After that, when the switches 9f and 9g are closed to the sides (d) and (a), respectively, current flows to the power transistors 4-6 and the light-emitting diodes 9j, 9l, and 9n turn on. In this manner, since the diodes are turned on the off by switching the switches 9g and 9f, it can be judged whether the IPM(intelligence power module) of an inverter is good or not.
