Title: Multiple transmission system
Inventor: TAKAI TAKAO
IPC: H04N7/08
Filed: 1991-10-01
Abstract: PURPOSE:To permit one carrier wave to simultaneously transmit more than two programs in the same time zone by modulating one carrier wave while repeating the changeover of more than two video signals of different source in a short cycle. CONSTITUTION:The transmission is performed by modulating the carrier wave 1 while repeatedly changing two signals, for example, a 'baseball' signal 2 and a 'rakugo' (the telling of long humorous stories) signal 3 in the very short cycle. On the reception side, a selection circuit selects a video signal of the same source. In short, for example, the 'baseball' signal 2 and the 'rakugo' signal 3 are switched in one screen unit, transmitted as the 'baseball' signal 2 and the 'rakugo' signal 3. On the reception side, the only program is selected by the selection mode. For example, when selecting the 'baseball' signal, the display is turned to the 'baseball' signal 2, void, 'baseball' signal 2, and void. The void is supplemented by video signal storage elements CF and RAM. When the 'baseball' signal is inputted first, it is outputted to the CRT as it is. The same signal 2 is stored in the VRAM, and the inputted VRAM signal is outputted to the next void period.

Abstract: PURPOSE:To improve turn-off characteristics at a high temperature by a method wherein a lattice-defect region is formed in the vicinity of a high-resistivity region in an anode region in a semiconductor device provided with a high- resistivity region between its anode region and cathode region. CONSTITUTION:Ions are implanted into an N<->-type Si substrate 1a and then diffusion is accomplished for the formation on the rear side a P<+>-type anode region 2 and, on the front side, an N<+>-type cathode region 4 and a P<+>-type gate region 5, for the construction of a static induction thyristor 1. After the construction of Al electrode 2', 4', and 5', a proton beam is applied, vertically from the side of the front surface of the N<->-type Si substrate 1a. This process produces a lattice-defect region 6 to contribute to reduction in the positive hole life ad turn-off time. It is so designed in this process that the peak Q in lattice-defect distribution will be found near an N<-> high-resistivity region 3 in the P<+>-type anode region 2. This design realizes an element shorter in turn-off time at a high temperature. This technique holds in the manufacture of the insulated gate bipolar transistor(IGBT), too.

Abstract: PURPOSE:To repeat tricolor exposure to accelerate printing while a light sensitive element is transported continuously and at constant speed by providing R.G.B. monochromic line light sources, a tricolor division crystalline liquid shutter which opens, receiving a color selection signal and a crystalline liquid shutter array which is synchronized with the time for opening of the shutter. CONSTITUTION:A tricolor division shutter 2 is provided in the optical path of monochromatic line light sources 1r, 1g, 1b. The crystalline liquid shutters 2r, 2g, 2b open for a specified time receiving a color section signal, and allow light to pass to a focus F. A crystalline liquid shutter array 3 opens at the positions of elements (3a, 3b, 3c...) for given colors for a specified exposure time, receiving an image signal. Then the shutter permits line dot-like, red, green and blue lights to pass to light sensitive paper 4 sequentially. In this case, tricolor exposure of data for a single line is repeated without interruption on the light sensitive paper 4 which is continuously fed at constant speed, thus completing the printing of a single color image. As described above, printing time can be significantly shortened while exposure accuracy is maintained, because the paper is fed continuously and at constant speed. At the same, time, the structure of feed rollers 5, 5 can be simplified and thereby the subject device can be manufactured at low cost.
