Abstract: PROBLEM TO BE SOLVED: To perform switching which is high in contrast ratio and high in the utilization efficiency of light. SOLUTION: Light which is made incident of a 2nd surface 12b of a prism 12 is guided to refractive index material layers 5 and 7 without being reflected by the surface of a light-transmissive substrate 10.

Title: Vertical deflection circuit
Inventor: KUBO KATSUHIKO
IPC: H04N3/16
Filed: 1993-04-28
Abstract: PURPOSE:To protect a transistor after output from being destroyed due to the fluctuation of a power source by connecting two transistor circuits with the detecting circuit of currents supplied to a deflection coil, and connecting capacity components and a diode with the connecting part. CONSTITUTION:At the time of steeply dropping the power source, since charge is stored in a capacitor 14, the potential of a pin P5 is made to steeply fall close to-Vcc beyond the ground potential. Then, a large current almost equal to the current obtained by converting a power supply voltage Vcc into current is allowed to be about to pass from a pin P9 to the pin P5. At that time, since a diode 15 is connected between the pin P9 and the emitter of a transistor TR15, and the pin P5 is connected with the collector of the transistor TR15, the current is allowed to pass from the pin P9 through the diode 15 to the pin P5. Therefore, the large currents can be prevented from running to transistors TR13 and TR14 or the like, and especially the transistor TR14 provided at an output stage can be prevented from being destroyed due to the large currents.
