    摘要： An object of the invention is to provide an injection molding process for preparing thermoplastic resin molded articles and an injection molding apparatus for use in practicing this process, the process and the apparatus being adapted to supply a blowing agent, especially a nonreactive gas such as carbon dioxide or nitrogen gas, to a thermoplastic resin continuously at a relatively low pressure with good stability to incorporate the agent or gas into the resin. As shown in FIG. 3, a resin in a cylinder (2) of an injection molding machine (1) as melted by rotating a screw (3) is mixed and dissolves carbon dioxide which is supplied to the molten resin from a gas supply opening (5) formed in the screw (3). An amount of the gas-incorporating molten resin is measured out and injected into a mold cavity to obtain an expansion-molded article. To incorporate carbon dioxide into the molten resin, the gas is supplied from a gas inlet (11) formed in a rear end portion of the screw to a portion (4a) not fed with the resin and positioned between front and rear screw flights and closer to the front flight, through a gas supply channel 6 extending through the screw and via the supply opening (5).

    摘要： The invention provides a foamed body of thermoplastic resin having a high expansion ratio, desired shape and cells of desired diameter, especially fine cells. The foamed body of thermoplastic resin is produced by filling the thermoplastic resin containing a foaming agent into a cavity 31 of a mold 2a and thereafter enlarging the cavity 31 to expand the resin. In this process, the cavity 31 is completely filled with the resin as melted and containing the foaming agent, then held in its shape as filled with the resin and enlarged to an increased final cavity width upon the average temperature filled in the cavity 31 reaching the range from the melting point of the resin to the melting point plus 30° C.

    摘要： Disclosed is a wireless communication system and the like that can avoid interference even if a plurality of networks coexist. The wireless communication system includes a primary user, cluster head equipment, and a secondary user. The cluster head equipment is for providing a local area network to a cluster region containing the abovementioned primary user. Also, the cluster head equipment contains: an acquisition means that acquires one or both—of information regarding the primary user and information regarding a primary signal—and the like; and a transmission means that transmits information to the secondary user. Then, using this wireless communication system, the secondary user performs cognitive wireless communication or the like on the basis of the information received from the transmission means of the cluster head equipment.

    摘要： There is disclosed a channel adjusting method capable of suppressing the occurrence of interference between a cognitive pilot channel (CPC) and an auxiliary control channel (ACS) in cognitive wireless communications. According to the channel adjusting method for use in cognitive wireless communications, initially, a connection using a cognitive pilot channel (CPC) is set up. Thereafter, it is determined whether or not a spectrum sensing channel (ACS) is to be utilized. If yes, it is then determined whether or not any interference occurs between the spectrum sensing channel (ACS) and the set-up cognitive pilot channel (CPC). This allows an adjustment to be performed such that no interference occurs between the cognitive pilot channel (CPC) and the spectrum sensing channel (ACS).
