    摘要： A dynamic damper in which the inner diameter (D2) of a first hole part formed at the axial one end part of a body part overlapped with a weight part in the radial direction is set smaller than the inner diameter (D3) of a second hole part formed at the axial other end part of the body part not overlapped with the weight part in the radial direction and tightened with a band member (D3>D2). The outer diameter (D1) of a drive shaft to be press-fitted into the first and second hole parts is set larger than the inner diameter (D2) of the first hole part and the inner diameter (D3) of the second hole part (D1>D3>D2).

    摘要： A spread spectrum receiving device is disclosed, in which data demodulation is effected in such a way that a received signal is divided into two parts, from which a COS PN code chip signal and a SIN PN code chip signal are obtained; that these chip signals are A/D-converted by means of A/D converters and then given to digital correlators; and that correlation outputs thus obtained are combined to synthesize a final correlation output. Further there are disposed a plurality of steering gates on the input side of the A/D converters. The a/D conversion can be effected in the neighborhood of a point, where the level of PN code chip waveforms is stable, owing to the fact that the steering gates are controlled by control signals obtained by processing the correlation outputs or output of the A/D conversion. In this way it is made unnecessary to raise the sampling frequency for the A/D conversion and to increase the number of stages of shift registers in the digital correlators.

    摘要： A GOLD code generating device in an SSC device is disclosed, which is so constructed that, in the case where two kinds of GOLD codes are used in the SSC device by the CSK system, etc., in order to generate a GOLD code by means of two m sequence codes, a first GOLD code is generated by using an m sequence code generated by one of the m sequence code generators and another m sequence code generated by the other m sequence code generator, while a second GOLD code is generated by using an m sequence code obtained by delaying the m sequence code generated by the other m sequence code generator by a predetermined number of chips.
