摘要： Prefoamed particles of a polyolefin resin are produced by dispersing starting particles of the polyolefin resin, which contains a volatile foaming agent, in a dispersant in a pressure vessel, heating the resultant dispersion to a temperature of at least the softening point of the starting particles in said pressure vessel and then opening the vessel at one end thereof so as to release the starting particles and dispersant into an atmosphere of a pressure lower than the internal pressure of the vessel. The release of the starting particles and dispersant is performed while feeding a heating liquid.

摘要： Method of producing a molded article of a foamed thermoplastic resin. A molten mass of an expandable thermoplastic resin is accumulated in an accumulator while it is prevented from foaming. A predetermined quantity of the accumulated thermoplastic resin is ejected rapidly from the accumulator into the atmosphere so that the thermoplastic resin commences foaming. The ejected thermoplastic resin is placed in a mold cavity before the foaming expansion has been completed and is compressed. The expansion and molding of the ejected thermoplastic resin is completed in the mold while controlling the compression pressure to obtain a foamed molded article.

摘要： There is provided a logic device wherein an alternating input signal having a frequency which is one of two frequencies allotted to two input logical values, respectively, positive logic "1" and negative logic "0", is inputted to the device. An output logical value is decided depending on the determination which frequencies the input frequency coincides with or not, and an alternating output signal having a frequency which corresponds to the output logical value is delivered out of the device. The logic device, even when constituted with semiconductor elements, can have highly reliable fail-safe capability and can be reduced in size and weight.

摘要： A handover method is to provided by which a station can move between access points with interruption in communication minimized. An access point assigns mobile stations existing in its own wireless network to identification codes, different from station to station, to thereby carry out association, and thereafter transmits beacon frames each containing a different identification code to the mobile stations. The identification codes are allocated beforehand specifically to each of the access points included in the wireless LAN. When the station is handed over to an adjacent access point, the adjacent access point transmits beacon frames containing the corresponding identification code to that station. Thus, the station is able to continue communication without recognizing the transfer from one wireless network to another.

摘要： An access point is provided which is able to secure QoS of multimedia traffic. In the method of controlling QoS for wireless LAN base station apparatus used in a wireless LAN system operating in accordance with IEEE 802.11 standard, the base station or access point is included in a network working in an infrastructure mode with other mobile stations controlled in access by the DCF function. When the access point is receiving a first frame sent from the mobile station and holds a multimedia frame to be sent with high-priority after having received the first frame, it loads the Duration/ID field of an ACK frame responding to the first frame with a time required for transmitting the multimedia frame, and then sends the ACK frame.
