Inventor: OGURA ICHIRO
IPC: H04N9/808
Filed: 1985-07-11
Abstract: PURPOSE:To minimize deterioration of picture quality by scattering a data to be corrected in a pattern in the unit of samples of a required number for the operation to separate a luminance signal at reproduction even when an error not corrected by an error correction code takes place. CONSTITUTION:Shaffling circuits 4a, 4b, 4c apply proper operation to a signal sent from a channel separator 3 at first and divide it into plural sample sets so as to separate only a color signal. Figure shows the relation between a sampling point and a sub carrier phase as to the l-th line and the (l+1)-th line in sampling the NTSC color television signal at 4fsc. Two sample points Xl,i, Xl+1,i used for the operation to obtain a luminance signal and the color signal are combined and the order of data coming consecutively in time series at random or under a prescribed rule. At reproduction, in a deshaffling circuit, the arrangement is restored to the original sampling by rearranging reversely with the shaffling circuit.

At the same time, the signal ST1 is delivered outside from a contact (b) of the circuit 16 via a terminal 191. This delivered signal ST1 is applied to the computers 14 of other boards 12-1i respectively. Receiving the signal ST1, each computer 14 transmits immediately an arithmetic start signal ST2 to each interporation arithmetic circuit 3. The input/output of the signal ST1 is carried out with a board 1n as long as the circuit 16 of the board 1n is kept under a connection state J3. Therefore an independent actuation is possible for the board 1n.

Abstract: PURPOSE:To obtain a ceramic sintered member having high strength at high temp. and excellent in oxidation resistance by providing a surface layer composed of alumina particles with an average particle size of a predetermined value or more on a substrate composed of silicon nitride. CONSTITUTION:A ceramic sintered member consists of a substrate 1 composed of silicon nitride and the surface layer composed of alumina particles with an average particle size of 20mum or more formed on the substrate. As mentioned above, the ceramic sintered member has such a structure that the surface layer 2 composed of alumina particles excellent in oxidation resistance and corrosion resistance is formed on the substrate composed of silicon nitride excellent in strength and tenacity. Therefore, the surface of the substrate 1 is protected by the surface layer 2 and prevented from being directly exposed to an oxidative or corrosive atmosphere. Since the surface layer is composed of alumina particles with an average particle size of 20mum or more, even if tensile residual stress is applied to the surface layer by the difference of the coefficient of thermal expansion with the substrate 1 composed of silicon nitride, the surface layer has strength withstanding tensile residual stress.
