Title: Video signal processor
Inventor: KAWAKAMI TOSHIKATSU
IPC: H04N5/46
Filed: 1990-07-03
Abstract: PURPOSE:To reduce memories and to simplify its periphery by performing double scanning conversion and compression conversion with the identical circuit. CONSTITUTION:ED-processed active line signal (active Y) and an interpolation line signal (interpolation Y) are written in memories 6-1-6-4 by a writing reset signal WRST for each 2H. The reading is performed by the active RRST generated for each 2H delayed for 1H from a reading reset signal WRST, and a interpolation RRST delayed for 0.5H more. The active RE and the interpolation RE are generated in turn. The RE is designed to be obtained after counting a clock for 910, and a starting position is varied to be at the center at all times according to the frequency of the clock, since when the frequency of the clock becomes higher, the width of the RE is narrowered. The double-speed synthetic data can be obtained by synthesizing the data from the memory. Thus, the memories are reduced, and not only simple double speed but also further compression can be performed.

Filed: 1995-07-12
Abstract: PROBLEM TO BE SOLVED: To generate finite elements for structure analysis which need not be corrected after being generated without altering a conventional CAD system and a computer system while sufficiently reflecting the experience of a designer. SOLUTION: A wire frame 23 in a final shape consisting of plural polygonal elements is inputted to the CAD system. To generate input data for the structure analysis, the wire frame 23 is read as line information in a processor and processed to find the coordinates of the intersections of all the pieces of line information, and the respective pieces of line information are divided into pieces LM-1 to LM-12 of information connecting adjacent coordinates. On the basis of the pieces LM-1 to LM-12 of information divided having nodes at the coordinates of both ends of the divided pieces LM-1 to LM-12 of information, plural finite elements 105 and 106 in polygonal shapes are generated.

Title: Afc circuit
Inventor: IMAI MASASHI
IPC: H04N5/50
Filed: 1988-07-15
Abstract: PURPOSE:To attain automatic switching by controlling the opening and closing of a switch with prescribed timing at the time of keyed AFC and closing the switch at the time of average value AFC. CONSTITUTION:A keyed switch 15 is always turned off in order to execute average value AFC operation when a composite type satellite transmitting station is received. When a component type satellite broadcasting signal is received, the switch 15 is turned on only during a clamp period and turned off during a hold period. The control of the switch 15 is executed by a control signal 10a from a mode switching circuit 10. A receiving mode detects a pulse to show the clamp period in a component type demodulating signal and decides the synchronization of the pulse. Then, in case of the correct period, such a time is decided as the time of component type broadcasting signal reception. Then, in case of the different period, such a time is decided as the time of composite type satellite broadcasting signal. Accordingly, a switching circuit excepting for the switch 15 is not needed.
