Abstract: A receiver of a spread spectrum communication system comprises a plurality of despreading circuits, a rake circuit, and a path searcher. The plurality of despreading circuits despreads received signals having multipath components at predetermined timing allocated thereto. The rake circuit performs rake combining of the signals despread by despreading circuits. The path searcher forms a first window showing a part of a search range and calculates delay profile data of said received signals in said first window to search an effective path, forms at least one second window in the search range except said first window and calculates delay profile data of said received signals in said second window, and detects timing at which said received signals are despread based on calculated delay profile data to allocate the detected timing to said despreading circuits.

An image recording support material is produced by the above method. A method of recyling an image recording support material, based on the above method, is also conducted.

Abstract: In a regenerating method and apparatus of a recorded material in which at least a portion of the recorded material in the vicinity of a surface thereof on an image forming side is wet and expands with a liquid, the wet and expanding liquid (also called an image removing accelerating liquid in the following description) is provided to the recorded material so that the portion of the recorded material in the vicinity of the surface thereof is wet and expands with this liquid. A separating member comes in contact with an image forming substance having a film shape and a thermoplastic or thermally melted property and formed in the vicinity of the surface of the recorded material in a state in which joining force between the image forming substance and the recorded material is reduced. An image in the vicinity of the surface of the recorded material is transferred onto the separating member so that the image forming substance on the recorded material is removed therefrom.

Abstract: A predetermined processing liquid is supplied by a liquid supplying unit to a sheet of transfer paper having a surface on which toner is stably attached. An adhesive state of the toner on the transfer paper sheet is changed to an unstable adhesive state. The processing liquid is constructed by water, aqueous solutions of a surfactant, a water-soluble polymer, etc. The transfer paper sheet including the processing liquid is fed to a toner separating unit. While the toner is heated and pressurized in the toner separating unit, the toner is attached to a separating roller having a surface on which the softened toner is easily attached. The toner separating unit then separates only the transfer paper sheet from the surface of the separating roller by a separating claw. The processing liquid is removed from the transfer paper sheet by heating the transfer paper sheet, etc. using a drying unit such that the transfer paper sheet can be reused for a copying machine, etc.

Abstract: After a row address and a column address are supplied to a dynamic RAM in response to a row address strobe signal and a column address strobe signal, respectively, a high impedance state is maintained for column address access time period after the fall timing of the column address strobe signal, thereafter data is outputted to a data bus, and the high impedance state of the data bus is quickly resumed after the rise timing of the column address strobe signal. If different column addresses of RAM at the same row address are successively read, data are read and outputted to the data bus in response to a change only in the column address strobe signal, and thereafter, even after the high impedance state of the data bus is quickly resumed, a data value is held by the data bus until the dynamic RAM outputs the data.
