摘要： Multi-carrier transmission is performed without inserting a repetitive signal into guard interval periods. A transmitter provides guard interval periods by using a null signal to save transmission power and prevent the deterioration of the SN ratio. Delayed waves at the head of each received symbol cause high-frequency waves to occur and carriers to interfere with one another. Accordingly, a receiver adds a component following each received symbol to a delayed-wave component at the head of the received symbol. As a result, the delayed-wave component at the head of the received symbol and the added component become continuous in wave form and subcarriers do not interfere with each other.

摘要： In a radio communication such as a radio telephone system or the like, a transmission channel which can accommodate a change in a transmission capacity is set. While a terminal apparatus and a base station are in communication for transmitting a predetermined information using a predetermined transmission channel, a signal requesting to set another transmission channel is transmitted using a part of the predetermined transmission channel to initiate communication between the terminal apparatus and the base station through the other transmission channel.

摘要： In order cope with a change of the transmitting capacity in a wireless telephone system. A number of transmission channels are set within the transmission frequency band prepared for each base station. When a communication is made between the terminal equipment and the base station through the transmission channels, at least a first transmission channel and a second transmission channel are set as the transmission channel depending on a class of information to be transmitted. The first transmission channel is set to have a fixed transmitting capacity and the second transmission channel is set so that the minimum transmitting capacity may be defined and the transmitting capacity greater than the minimum transmitting capacity may be set depending on the setting condition of the transmission channels within the transmission frequency band prepared.

摘要： A pulsation damper mounted in a fuel chamber (23) of a high-pressure fuel pump (20) is provided with a diaphragm (11) having a flat section (11a) displaced when fuel pressure is applied thereto, a pump cover (10) for supporting the diaphragm (11), and a gas chamber (12) formed by the diaphragm (11) and the pump cover (10). Pressure pulsation occurring in the fuel chamber (23) is suppressed by displacement of the flat section (11a). The diaphragm (11) is formed in a closed-bottomed tubular shape with the flat section (11a) located at the bottom and has a projection (11b) provided to the periphery of the flat section (11a) and projecting to the side opposite to the pump cover (10). A tubular peripheral section extending from the outer periphery of the projection (11b) so as to be vertical to the flat section (11a) is fitted over the pump cover (10). The externally fitting portion of the tubular peripheral section is a joint section (11c) joined to the pump cover (10).
