Title: Vertical direction filter for video signal
Inventor: AKIBA TOSHIYA
IPC: H04N5/14
Filed: 1989-04-18
Abstract: PURPOSE:To obtain an optimum output video signal having a space frequency component as high as possible within a range where no return distortion is produced in the vertical direction by attenuating each high vertical space frequency component of a video signal in response to plural vertical reduction factors before the signal is written into a frame memory. CONSTITUTION:A mobile contact 43f of a switch tap 43 is connected to a fixed contact 43b. Thus the alternating currents flowing to the resistors 39A and 39B having the resistance value 2R are mixed and supplied to a resistor 47 having the load resistance value R since the input impedance of a base-grounded transistor 45 is so small that can be neglected. When the contact 43f of the tap 43 is switched to fixed contacts 43b-43e, the vertical reduction factors of images equivalent to one screen are set at 1/2, 1/3, 1/4 and 1/6 respectively. As shown in the diagram, the highest space frequency can be set at about 1/n just by applying the weighted average to (n) pieces (n=2, 3, 4, 6) out of a luminance signal Y and its delayed luminance signals Y1-Y5 via an analog circuit.

Title: Method for joining ceramics and metal
Inventor: NAKADA HIROHIKO
IPC: C04B37/02
Filed: 1987-04-21
Abstract: PURPOSE:To securely join ceramics and metal in a short period of time by subjecting a metal or alloy which is interposed between the ceramics and the metal and reacts with the ceramics to melting by an electron beam. CONSTITUTION:The metal or alloy which reacts with the ceramics in a molten state is interposed between the ceramics and metal to be joined. The metal or alloy consisting of >=1 kinds among Ti, Ca, Zr, Al, Nb, W, Mo, Ni, Fe, and Tl and Ti-Ca-Ag alloy are adequate as the above-mentioned metal or alloy. The interposed metal or alloy is then melted by projection of the electron beam thereto for about several seconds. The ceramics and metal are thereby securely joined. Since the electron beam is focused and projected to the ceramics and metal in a short period of time, thermal stresses are decreased. This method is advantageous for joining of thermally weak materials as well.
