摘要： A technique for stably receiving an orthogonal frequency division multiplexed signal by means of a simple structure. Delay circuits 9–11 add delay times to the signals simultaneously received by antennas 1–4 in such a way that the delay time difference between any two signals is the reciprocal or more of the bandwidth allocated to one subcarrier of orthogonal frequency division multiplex. Thus, the signal synthesized by a mixer 12 can be assumed to be substantially equivalent to the received signal in a multipath environment. Since the delay time differences among the signals simultaneously received by the antennas 1–4 are sufficiently shorter than the length of the guard interval section, the margin prepared for actual arrival of a delay wave because of multipath is sufficiently ensured.

摘要： An AM neighboring interference removing method and circuit is provided which can select only a desired AM modulation wave even if an interference AM modulation wave is partially superposed upon the desired AM modulation wave. An AM modulation wave desired to be received is multiplied at multipliers by local oscillation signals having frequencies 3fc/2 and fc/2 where fc is the carrier frequency of a neighboring interference AM modulation wave. High frequency components contained in the outputs of the multipliers are removed by low-pass filters. Of the outputs of the low-pass filters, the carrier frequency of the neighboring interference wave is fc/2 and the AM carrier frequencies of the AM stereo modulation wave are (fc/2+fα) and (fc/2−fα), where fα is a difference frequency between the AM carrier frequency of the AM stereo modulation wave and the carrier frequency of the neighboring interference wave. A subtractor subtracts the output of one of the low-pass filter from the output of the other to thereby cancel out the neighboring interference wave. This subtraction signal is passed through a low-pass filter having a cut-off frequency of fc/2 to derive only the AM stereo modulation wave.

摘要： A disc cramp device which holds a disc by sandwiching it by a turn table and a cramper, according to the present invention, includes a cramper arm which is rotated in a direction to move close to the turn table and a direction to move away from it, a plate spring member, a part of which is fixed to the cramper arm, which lifts the cramper during an uncramping time, and which presses an upper center of the cramper in a direction of the turn table during a cramping time. It is constructed so that by providing tongue pieces for pressing the upper center of the cramper at a tip end portion of the cramper arm, the plate spring member presses the cramper while it is held at both sides during the uncramping time, and the plate spring member is pressed by the fixing member to be elastically deformed during the uncramping time. Consequently, according to the disc cramp device of the present invention, the number of components is reduced, and the height of the space for transferring the disc can be made large with respect to the height of the entire device, in addition to which, the driving force in a cramping and uncramping operations can be made small.
