Abstract: A packaged-body producing method that minimizes damage to packaged bodies due to constriction or the like and that enables formation of packaged bodies in various shapes is provided. The method includes a first step in which a plurality of packages 10 accommodating toilet paper rolls or the like are stacked, and recesses are provided at predetermined positions of the stacked form; a second step in which a packaging film 20 is spirally wound on the sides of the package stack form; and a third step in which the packaging film 20 is wound so as to cover the circumference, including an upper end portion and a lower end portion, of the package stack form.

Abstract: A method of producing a packing body includes the steps of: stacking a plurality of packaging bodies, placing reinforcing sheet materials so as to wrap outer peripheries of side surfaces of the packaging bodies that have been stacked, and fastening the packaging bodies that have been stacked by placing a fastening band from an outer side of the reinforcing sheet materials. The placing step includes placing the reinforcing sheet materials on the side surfaces of the packaging bodies to protrude an end portions of the reinforcing sheet material from an upper surface of a packaging body in an uppermost layer and from a lower surface of a packaging body in a lowermost layer. The fastening step includes bending the end portions, covering an edge portion of each packaging body, and placing the fastening band on the edge portions with the reinforcing sheet materials interposed therebetween.

Abstract: A method for manufacturing a marked toilet paper roll by winding a sheet of wide toilet paper a predetermined length about a winding shaft to form a log roll and by cutting the log roll at a predetermined width into a plurality of toilet paper rolls, the method including marking stamps at intervals, each interval of the predetermined width, on an end portion of a winding end of the log roll before the log roll is cut into the toilet paper rolls.

Abstract: An OFDM signal communication system used in broadband mobile communication, achieves stable operation under severe frequency selective fading environments, giving high quality. The OFDM signal communication system which transmits OFDM signals over the same radio frequency from N transmitting antennas, has an inverse matrix computer for computing an N×N inverse matrix constituted by propagation coefficients for respective propagation paths between each of N transmitting antennas and each of N receiving antennas, and a subcarrier demodulator which separates the signals of the respective propagation paths, based on the obtained inverse matrix.

Abstract: In a wireless access system which uses the sector antenna of a radio base station to transmit an access channel to and receive an access channel from a radio terminal in each frame, and which switches the sector at each frame, the sector ID s is set in a specific functional relation to the access channel ID a, and a radio terminal which communicates with a radio base station transmits and receives in accordance with the access channel ID a without knowing the sector ID s.

Abstract: A method for producing a packed article of a plurality of box-like packages having the same dimension is provided. The method comprising the steps of: forming a first layer of packages by arranging a plurality of box-like packages in a predetermined pattern; forming upper layers of packages, each upper layers including the same number of the packages as that of said first package and having the same pattern as that of said first layer; forming an intermediate layer of packages, said intermediate layer including number of packages less than that of said first layer or said upper layers; and disposing said intermediate layer between said first layer and the upper layer adjacent to said first layer so as to form spaces on opposite sides of said intermediate layer.
