Abstract: The present invention provides a process cartridge includes a first unit and a second unit separable (detachable) from the first unit. The first unit includes a photosensitive member, a developing unit that forms an image on the photosensitive member, and a cleaning unit that collects residual toner from the photosensitive member. The second unit includes a toner hopper unit that supplies toner on the photosensitive member, and a waste toner box that stores the collected residual toner.

Abstract: Various kinds of wastewater and water such as methane fermentation digestion liquids, domestic wastewater, sewage, service water, culture pond water, wastewater defined by an active sludge law and wastewater from food industries are decomposed, cleaned and treated with a high efficiency with oxygen radicals, hydroxyl radicals and diphenyl para picrihydoral radicals, and injurious materials are decomposed, cleaned and treated by oxidizing and reducing functions. An apparatus for cleaning dissolved organic matters and a trace amount of injurious materials consisting of a anode which is formed or welded by coating clay or glass with a material prepared by mixing 2 to 15% by weight of a transition metal with 1 to 10% of an oxidized transition metal and sintering the glass within a range from 800 to 1500° C.

Abstract: A fungus belonging to the order of Agaricales, such as mushroom, is cultured with good efficiency by using a liquid culture medium in such a way as to prepare the mycelia separated from the culture medium and the culturing liquid thereof can be served as such for food use. A liquid culture medium containing 3 to 16 g/liter of sucrose and 1 to 6 g/liter of maltose as the carbon source and 0.3 to 1.2 g/liter of yeast extract as the nitrogen source is inoculated with Agaricus mycelia and culturing is conducted by blowing thereinto sterilized air of 20 to 90% of the oxygen concentration.

Abstract: Transaction of electric power has been conventionally conducted mainly to cope with power demand of a large-volume customer, and in which a power customer presents a power demand for covering a certain period of time, and power companies tenders for the offer. In this manner, the transaction was done in reliance on manpower.

Abstract: Disclosed is an efficient method for culturing an edible basidiomycetous fungus such as Mushroom Agaricus Blazei Murill in a liquid culture medium to give fungus aggregates of several centimeter size. Characteristically, the liquid culture medium is formulated with sucrose as a carbon source in the form of crude cane sugar in combination with a water-insoluble growth-supporting material in the form of a fine powder to serve as the core of the fungus aggregates as selected from crushed sugarcane, sugarcane bagasse, pine trees and wheat bran. Further characteristically, the culturing procedure is carried out under an oxygen-enriched condition by blowing oxygen-enriched air of at least 30% by volume oxygen into the culture medium under pressurization at 0.12 to 0.5 MPa (absolute) in a specified blowing rate.

Abstract: A software management system for processing, maintaining improved reliability, a software delivered on a wide-area network. A center server 1 includes a script 12 describing the operation of the application 11, and a fault countermeasure means 13 for coping with the occurrence of a fault. A local server 3 includes a network-directed language execution environment 31, a remote management means 32 for downloading or deleting the application, a script interpretation means 33, and a highly reliable means 34 for recording event data that occur while the application is being executed, for managing the data when the fault has occurred, and for executing the restoration processing.

Abstract: An object of this invention is to offer an incubation carrier for achieving high activity and high density of the microorganism in a bioreactor, in a treatment of waste water, etc.

Abstract: The present invention relates to magnetic carriers in which microorganisms requiring carriers for their growth in the step of treating wastewater have been immmobilized, a process for producing the carriers and a method of treating wastewater. The present invention provides microorganisms-immobilized carriers with a high amount of microorganisms immobilized for use in wastewater treatment, the movement of which is controllable in a treatment chamber by magnetic force. Further the present invention provides a process for producing said carriers easily and a method for treating wastewater efficiently.

Abstract: A receiving apparatus for receiving information transmitted from a bottomhole to a surface by means of electromagnetic waves. The receiving apparatus includes a receiving antenna for receiving a transmitted signal from the bottomhole, a noise detector for detecting noise current received by the receiving antenna, and a noise canceller for removing noise components received by the receiving antenna by comparing an output signal from the receiving antenna and an output signal of the noise detector. The noise canceller is a noise canceller using parallel adaptive filters, and includes a plurality of adaptive filters arranged in parallel fashion, an adder for summing output signals of the plurality of adaptive filters, and a subtracter for subtracting an output signal of the adder from a main input signal.
