Title: Manufacture of circuit board
Inventor: TSUMITA YOSHIYUKI
IPC: C04B41/80
Filed: 1990-03-09
Abstract: PURPOSE:To remove a burr produced by a laser scribing operation by a method wherein the laser scribing operation which forms a dividing groove used to divide a baked alumina substrate into individual circuit boards is executed and, after that, the substrate is baked again at 1500 deg.C for four hours. CONSTITUTION:An alumina substrate 1 is a procelain substrate composed of alumina whose purity is, e.g. 96%; the alumina substrate 1 is divided to manufacture individual thick-film circuit boards. A dividing groove 3 is formed in a desired size on the surface of the alumina substrate 1 by a laser scribing operation using, e.g. a carbonic acid gas laser. After that, the alumina substrate 1 is baked again at 1500 deg.C for four hours. Thereby, a burr produced by the laser scribing operation can be removed; the surface near the dividing groove in the alumina substrate becomes as smooth as the surface in other parts. As a result, it is possible to prevent a printing defect of a conductor pattern 2, a resistance or the like formed in this part.

Title: Divided television signal transmitter and receiver
Inventor: KAWAI KIYOYUKI
IPC: H04N7/081
Filed: 1988-03-10
Abstract: PURPOSE:To secure a signal/noise ratio(S/N) when the additional signals are received and reproduced by transmitting these additional signals after converting into the non-interlace signals having 525 scan lines and the 30Hz frame frequency vie the frame thinning operation. CONSTITUTION:The additional signals are transmitted at the transmission side with one frame thinned every two frames. At the reception side the signals of the thinned frames are interpolated with the received additional signals and, at the same time, the degrees of attenuation of these interpolated signals are controlled by the movements of pictures. In such a way, since the quantity of information is reduced by the frame thinning operation at transmission of the additional signals, disturbance of the additional signals can be reduced to a primary signal. Furthermore the information lost by the frame thinning operation is supplemented by the frame interpolation at the reception side. Therefore it is possible to avoid the flicker produced in a large area and to eliminate the deterioration of a screen.
