Title: Digital television signal processing system with error correction
Inventor: HENRI GAATON RUISU JIYUNIA
IPC: H04N11/00
Filed: 1983-10-20
Abstract: A digital television processing system is provided which contains error correction capability, A digital processing section (23, 26, 31, 36, 37, 38, 45, 46, 51, 52) accepts first digital samples as input and produces modified digital samples (Yc) as output. These respective digital samples each contain picture information. A processing stage (23, 45, 46) in the digital processing section, however, when supplied with selected input digital samples, produces digital output samples (Yp) subject to error. The modified picture information, derived from the output samples subject to error possibly contains erroneously modified picture information. A digital-to-analog converter (49, 50) accepts the modified (possibly erroneous) digital samples and produces an analog signal (Y min ) containing picture information subject to error. 
<??>An error detector (70) is coupled to the digital processing stage for detecting the presence of the error. Correction means (48) are coupled to the digital-to-analog converter to change the analog signal upon detection of an error to a different analog signal such that the picture information is corrected for the effects of the error.

Title: Gas-insulated switchgear
Inventor: YUZA YASUYUKI
IPC: H02B13/02
Filed: 1999-07-13
Abstract: PROBLEM TO BE SOLVED: To achieve integration, and at the same time to reduce installation space by providing a connection seat on the opposite surface of each tank in an adjacent unit, by connecting the connection seats each other, and by arranging bus pipelines at height so that they do not interfere mutually. SOLUTION: Height H3 of a pipeline 8 in a receiving unit 10 is set higher than normal one. On the other hand, height H4 of a pipeline 14 in a transformer primary unit 16 is lower than normal one, thus increasing the difference between the height H3 and H4, and preventing the pipelines 8 and 14 from mutually interfering even when the receiving unit 10 approaches the transformer primary unit 16. Even when the receiving unit 10 and the transformer primary unit 16 are fixed to a common trestle 20, the connection force between the both is not insufficient since merely the lower parts are connected, thus providing connection seats 18 at both the sides of tanks 6 and 12 to connect the upper part of the tank 6 to the broken part of the tank 12.
