Title: Plug flow type digesting method
Inventor: IMOMOTO MASAHIRO
IPC: C02F11/04
Filed: 1983-10-20
Abstract: PURPOSE:To cause efficient methane fermentation of org. acids by generated bacteria by drawing the digested sludge out of the digestion chamber on the outflow side and returning intermittently the drawn-out sludge to the digestion chamber on the inflow side after a specified period when the return is stopped. CONSTITUTION:Raw sludge 3 is charged into a digestion chamber 2 on the inflow side and as the sludge 3 is charged into said chamber, the treated liquid 4 in each chamber 2 overflows successively from said chamber 2 on the inflow side to the chamber 2 on the outflow side. The digested sludge 5 and eluate 6 are drawn out of the chamber 2 at the rear end on the outflow side. The sludge 5 is returned by a return pump 7 to the chamber 2 at the above-described front end. The return of the sludge 5 is accomplished intermittently; for example, the sludge is quickly returned for a specified time after a specified period when the return is stopped.

Title: Combustion of internal-combustion engine utilizing wet steam and supplying device thereof
Inventor: YOSHIDA TOSHIO
IPC: F02M25/022
Filed: 1983-10-22
Abstract: PURPOSE:To burn the mixture of air, wet steam and fuel and improve fuel consumption and output by a method wherein the air, induced into the combustion chamber of the internal-combustion engine together with the fuel, is mixed with the wet steam of proper temperature and amount, which is generated artificially. CONSTITUTION:Upon starting the engine E, a solenoid valve 2 is closed when the engine temperature is low, therefore, feed water from a pump P returns into a tank T through a returning pipe 19. Accordingly, the water is not fed to an evaporator 6, the air, flowing through a warm air supplying pipe 9 is sent into the evaporator 6 and flows into an air cleaner 13 through a mixing air supplying pipe 12. On the other hand, when the temperature of the engine E is risen and the temperature in the evaporator 6 arrives at a set value, a temperature regulator 15 opens a solenoid valve 2 by the detection of a temperature sensor 14 and water feeding to the evaporator 6 is started. Accordingly, water, heated in a fore exhaust pipe 4, flows into the evaporator 6, becomes the wet steam and is mixed with the warm air of the warm air supplying pipe 9, thereafter, is mixed with the fuel in a carburettor 20 and is sent into the engine E.

Title: Organic photoconductive body
Inventor: ROBAATO BURAASU CHIYANPU
IPC: G03G5/047
Filed: 1989-08-01
Abstract: PURPOSE: To make it possible to obtain an org. photoconductor improved in wear characteristics by using charge transport layers higher in the concn. of a charge transport material in the lower part than in the upper part. CONSTITUTION: Mixing is induced and the concn. gradient of the charge transport material is obtd. by using a common solvent for forming both layers by increasing the concn. of the charge transport material in the layer next to a charge generating layer and making the concn. of the outer layer relatively lower. The charge transport material is, for example, 4- diethylaminobenzaldehyde diphenylhydrazone, etc. The transport layers provided with the concn. gradient in such a manner are improved on photoresponse as compared with the single transport layer and the wear is lessened, but the electron copying characteristics of the two transport layers are invariable. As a result, the photoconductor improved in the wear characteristics is obtd. without deteriorating the electronic copying characteristics.
