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).

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： According to one embodiment, in a data write operation, the average value of the emission power detected by a front monitor is obtained via a low-pass filter and a sample hold circuit. In the write operation, erase power controlled by an erase APC is obtained via a sample hold circuit. While an LD is emitting light with the erase power, an erase current is determined from the output voltage of the erase APC. On the basis of the average power, the erase power, the erase current, and a waveform of the recording pulse, a current-to-emission-power characteristic of the LD is estimated. Furthermore, on the basis of the current-to-emission-power characteristic, the peak power in the write operation of the LD are controlled.

摘要： A playback device 10 generates a PN code with a start timing based on a video sync signal, and generates a PN inverse code which has a reverse polarity to that of the PN code with a timing based on the video sync signal. An anti-duplication control signal is spectrally spread using this PN code, superimposed on the video signal and supplied to a recording device. A PN inverse code which is the same as the PN inverse code used in the playback device is also generated in the recording device based on the video sync signal, and reverse spectral spread is performed using this PN inverse code.
