摘要： A combination-information creating unit creates combination information for determining a maximum number of combinations or a maximum frame length according to a usable radio band and a modulation method and combination possibility information for indicating that a combination of frames is possible. A frame combining unit combines a plurality of frames received from an outside access line, based on the combination information, the combination possibility information, and predetermined packet information. A frame dividing unit divides a combined frame included in a received radio signal into individual frames.

摘要： A communication method for a CSMA network including a radio terminal and a base station supporting RTS/CTS, includes: the base station transmitting and RTS frame to the radio terminal during a transmission-suspend-period in which the radio terminal suspends transmission to prevent a collision of packets; the radio terminal transmitting an RTR frame to the base station after the transmission-suspend-period has elapsed; and the base station transmitting a date frame to the radio terminal in response to the RTR frame.

摘要： An electromagnetic clutch includes a first rotatable member for connection to an external driving source and a second rotatable member for connection to a driven member. An annular magnetic member is connected to the second rotatable member through a plurality of leaf springs. A third rotatable member is connected to the second rotatable member to limit the axial movement of the annular magnetic member. A plurality of connecting and absorbing devices are fixedly disposed between the annular magnetic member and the third rotatable member. These devices absorb vibration and impact forces when the annular magnetic member is attracted to the first rotatable member. A device is provided for preventing the destruction of the connecting and absorbing device due to the impact force and vibration created upon engagement of the electromagnetic clutch.
