Title: Treatment of desorbed liquid of anaerobic digestion
Inventor: MORI NAOMICHI
IPC: C02F3/34
Filed: 1980-11-20
Abstract: PURPOSE: To remove the ammonia and org. nitrogen in desorbed liquid after anaerobic degestion effectively by separating the org. acids formed in an acid fermentation process of anaerobic digestion and supplying the org. acids to a biological denitrification process.  
     CONSTITUTION: After raw materials are subjected to an acid fermentation treatment in an acid fermentation vessel 1, they are fractionated to org. acids and sludge in an org. acid decomposing vessel 2. The separated sludge is fed to a methane fermentation vessel 3, where org. materials are separated to gaseous methane and carbon dioxide by methane germs. The slurry of methane fermentation is separated to digested sludge and desorbed liquid. The desorbed liquid is subjected to removal of BOD and a nitrification of ammoniacal nitrogen in an aeration tank 5, thence it is transferred into a denitrification vessel 6. The org. acids separated in the vessel 2 are supplied into the vessel 6. Since these org. acids are utilized as a carbon source for denitrification germs, nitrate nitrogen and the like are separated efficiently to gaseous nitrogen.

Title: Device for controlling paper feed in copying machine
Inventor: HIRONO TATSUO
IPC: G03B27/34
Filed: 1984-08-03
Abstract: PURPOSE:To permit variable power rate to be changed automatically when a newly selected paper is different from the first paper in size by selecting a plurality of paper feeders in response to the operation of a switch and controlling the magnification according to the selected paper size. CONSTITUTION:At the time of the initial mode selection, a feed paper size selection switch 4 and a variable power rate designation switch 2 are operated, whereby a unmagnification, e.g., B4 size, is displayed on a display unit 5. If a switch 4b for an intermediate paper feeder is selected, during copying in the first mode the B4 size is switched over to B5 for the intermediate paper feeder. Since an image-cut results in the original scale copying, the variable power rate is automatically switched over to 0.71 time magnification. The variable power rate is automatically selected according to the selected paper size, so that image- cut will never occur.

Abstract: PURPOSE:To simplify the circuit constitution and to facilitate the circuit integration by varying two control potentials in the same direction by the same width when the gain is varied. CONSTITUTION:A 1st pair of FETs comprising parallel connection of two FETs Q1, Q1' and a 2nd pair of FETs comprising parallel connection of two FETs Q2,Q2' are connected in series between power terminals 20 and 21.

Furthermore, control terminals 241, 242 applying different control potential to the gate of the other FET Q1, of the 1st pair FET and one FET Q2' of the 2nd pair FET are connected. Then in the case of varying the gain, the two control potentials are varied in the same direction by the same width. Thus, the circuit integration is easily attained with simple circuit constitution and since no operating point compensation circuit is required, a comparatively low bias voltage such as 2 or 3V is enough for the purpose.
