Title: Filter for purifying exhaust gas from diesel engine
Inventor: TEIBERIYUU MITSURAA
IPC: B01D46/10
Filed: 1987-12-23
Abstract: In filters for cleaning the exhaust gases from diesel engines having openpored foam ceramic bodies, the deposited soot particles are burned up at temperatures of between 550 DEG  and 700 DEG  C. at periodic intervals. In order to lower the inflammation temperature of the soot in the regeneration phase of the filter, the ceramic bodies are catalytically coated. The region of the openpored foam ceramic body first subjected to the flow of the exhaust gases of the diesel engines has at least partly a denser pore structure than the remaining foam body so that the inflammation temperature can be lowered since temperature peaks occur in these regions on account of increased soot deposits, which temperature peaks lead to inflammation of the soot located there and consequently burn up all the soot deposited in the filter.

Title: Video and audio signal multiplexing transmission system
Inventor: KAWAGUCHI YUKIHIRO
IPC: H04N19/85
Filed: 1990-11-27
Abstract: PURPOSE:To enhance transmission efficiency and to improve image quality by adding the flag bits to the extent that audio signals are not inputted into a frame format when the audio signals are not inputted. CONSTITUTION:A voice signal off detecting section 1 detects whether an audio signal AUDIO is inputted or not. A video signal VIDEO is inputted to the part of the audio signals in the frame format by a signal transmission side selector section 2S and the flag bits to this extent are inserted into the transmission frame format if the AUDIO is not inputted or not used. The video multiplexing signal VIDEO is then transmitted. The selection section 2R on the signal reception side judges whether the transmitted signal is both of the VIDEO and the AUDIO or only the VIDEO in accordance with the flag bits. The signals are then selected and outputted. The information on the videos which can be transmitted is increased in this way, by which the transmission efficiency is enhanced. Further, the resolution of the image quality is improved.
