Title: Television video signal scrambling system
Inventor: INABA MASAO
IPC: H04N7/169
Filed: 1983-11-09
Abstract: PURPOSE:To obtain a scramble system put into practical use essentially by dividing each line including a synchronizing signal of a television video signal into two sections and transmitting the signal while replacing the divided two sections. CONSTITUTION:An original signal is transmitted from a part 5 among parts 0- 15, and when the part 14 before the part 15 is transmitted, then the remaining parts 0-5 are transmitted. In this case, the number of picture elements of the original signal and the picture element after rotation are equal and while the 15th picture element of the original signal is not transmitted, the 5th picture element is transmitted twice, at the start and end of the transmission. Since the picture element is transmitted twice, the timewise margin due to the overlapping around the joint of the pictures is caused and since the part is overlapped even if the switching is conducted by a high speed electronic switch, the defect at the joint does not appear on the restored TV signal.

Filed: 1990-08-09
Abstract: PURPOSE:To reduce a space necessary for joining operation and to perform pressure welding excellent in joining quality by installing a transparent body passing laser beam at the front opening of a clamping body on the side passing the laser beam. CONSTITUTION:Materials 6a, 6b to be welded are clamped between the transparent body 100 and a lower side tip 5 and irradiated with laser beam 9 under this state.
