摘要： A spectrum spread signal spread by a spread code synchronized with a synchronous signal accompanying to an information signal is superimposed on the information signal and is then transmitted and the spectrum spread signal is then detected using the spread code for detection synchronized with the synchronous signal from the information signal on which the spectrum spread signal is superimposed. A value of the information signal on which the spectrum spread signal is superimposed is added or subtracted depending on the chip value of the relevant spread code for detection in each chip of the spread code for detection. The spectrum spread signal is detected by determining whether the added/subtracted value has exceeded the predetermined threshold value or not.

摘要： A playback device 10 generates a pseudo random noise (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.

摘要： A spread code generation section outputs selectively one of a plurality of different spectral spread codes corresponding to an anti-duplication control signal for indicating the content of the duplication prevention control such as duplication permission, duplication inhibition, and duplication of generation restriction of a video signal in a recording medium. The plurality of spectral spread codes is different in phase or series, or generated by multiplying a specified spread code by the plurality of different orthogonal codes. An additional information signal is spectrally spread using the selected spread code, and superimposed on the video signal to output a combined information signal. The spectral spread code in the combined information signal is detected, duplication control of the video signal in the recording medium is performed correspondingly to the detected spectral spread code, and the additional information is extracted by performing inversion spectral spread on the combined information signal using the detected spectral spread code.

摘要： An image transmission method, image anti-duplication method, image anti-duplication device, and image recording medium in which information for anti-duplication control is superimposed on a video signal without deterioration of the resultant video signal and the information is extracted accurately and quickly to perform anti-duplication control. An output device starts generation of pseudo-noise (PN) corresponding to a PN code start timing signal generated based on a video sync signal. One chip interval of the PN code is divided into a plurality of divided chips corresponding to a PN code inversion timing signal HT, and an original value of a chip is inverted on an alternate one divided interval to generate a PN inversion code. An anti-duplication control signal is subjected to spectral spreading using the PN inversion code and superimposed on the video signal. In the recording device which receives the video signal from the output device, inversion spectral spreading is performed based on the PN inversion code generated in the same way as that generated in the output device.

摘要： When an information signal recorded in a magnetic card is updated by an information recording and updating apparatus, a spectrum spread signal corresponding to the updated information signal is generated and it is then recorded superimposed on to the information recorded previously in the magnetic card without erasing the old information. Since the information is spectrum spread, alteration is difficult. Moreover, the magnetic card may be discriminated whether it may be used or not by considering the old information recorded in the magnetic card when it is used.

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).
