Filed: 1980-11-05
Abstract: PURPOSE:To perform efficient reading operation by quantizing document data for one line of a document and classifying the quantized data by classes extracting the features, and converting resolution corresponding to the classes. CONSTITUTION:An analog signal for one line of a document, outputted through the scanning of a photoelectric converting circuit 1, is converted into binary-coded, quantized data through a quantizing circuit 2. Then, the one-line quantized data stored in a line buffer 3 is supplied to a feature extracting circuit 4, which detects complexity by the thickness of lines of a character pattern to output class-discrimination information which corresponds to the complexity. Further, a resolution converting circuit converts the resolution of the data in the line buffer 3 corresponding to the discrimination information and stored the result in a line buffer 7. A control information storage part 6, on the other hand, limits a storage area required to read the contents of an external storage device 8 corresponding to the discrimination information, and a standard character pattern in the area is converted similarly by a 2nd resolution converting circuit 9 and loaded into a dictionary memory 10.

Abstract: PURPOSE:To eliminate the breakdown of an insulating film by a temperature cycle between a room temperature and a cryogenic temperature by reducing the difference of the thermal expansion coefficient of component metal particles of a thin superconductive film and an insulating film. CONSTITUTION:A thin superconductive film 15 which is formed of a mixture 14 of ultrafine lead particles 12 and ultrafine dioxidized silicon or silicon particles 13 is formed on an insulating substrate 11 made of silicon. Then, an insulating film 16 of lead oxide is formed on a region faced with the film 15 on the surface of the particles 12 at the surface side of the film 15. Subsequently, a thin superconductive film 20 made of a mixture 19 of ultrafine lead particles 17 and ultrafine dioxidized silicon or silicon particles 18 for covering the film 16 is formed on the film 15. Since the thermal expansion coefficients of the particles 12, 17 and 13 are respectively 30X10<6>/ deg.C and 2.5X10<6>/ deg.C, while the film 16 has 10X10<6>/ deg.C, the difference of the thermal expansion coefficient between the films 15 and 20 becomes small.

Title: Method of purifying flue gas
Inventor: FURIIDORITSUHI DEIRUKUSU
IPC: B01D53/77
Filed: 1987-06-24
Abstract: A process for purifying flue gases by conducting the hot gases through a dry purification stage, and then through a pebble bed evaporator containing pebbles and a liquid. The flue gases then exit the pebble bed evaporator and are washed in a wet washing step. Waste liquid containing dissolved material from the wet washing step is then used as the liquid in the pebble bed evaporator; as this liquid evaporates in the pebble bed evaporator, solid precipitate forms on the pebbles. This solid precipitate is removed from the evaporator and is stored. Vapor from the pebble bed evaporator is condensed and used in the wet washing step. The purified flue gases exiting the wet washing step pass through a filter stage and are discharged.
