    摘要： A rotary mechanism of a machine tool (driving device) includes a first motor for carrying out rotary driving and positioning of a workpiece support (rotary stacking-receiving die assembly), and second motors for supplementing rotation of the rotary stacking-receiving die assembly. The stop positioning accuracy of the rotary stacking-receiving die assembly due to the second motors is lower than the stop positioning accuracy of the rotary stacking-receiving die assembly due to the first motor.

    摘要： Data sequences correspond to L different parameter sets (effective symbol length, guard interval length, the number of carrier waves) and transformed into parallel data by respective serial/parallel converters, which are allocated to respective carrier waves for OFDM and subjected to inverse discrete Fourier transform by inverse discrete Fourier transformers to produce sampled values for the transmission waveform in the time domain. The sampled values are transformed into serial sequences of sampled values by parallel/serial converters and then into a single temporal sampling sequence by a temporal sampling sequence switching unit. A frame synchronizing symbol is added to the temporal sampling sequence and then transformed into an analog base band OFDM signal before it is converted up to a transmission signal. The frequency bandwidth of the OFDM signal is made smaller than a predetermined value defined by the bandwidth of the available transmission channel. As a result, an OFDM signal that can be received well regardless of the mode of reception can be transmitted.

    摘要： A lubricating system for a valve seat of an internal combustion engine produces a lubricant oil film on the valve seat (7) of a seat ring (2) providing the valve seat. At least a part of the seat ring (2) providing the valve seat surface (7) is made of a porous material (6, 9) readily containing lubricant oil. The outer cylindrical surface of the seat ring (2) is formed with an annular groove (4) along its circumferential direction. A cylinder head (1) to which the seat ring (2) is fastened is formed with an oil passage (5) for feeding lubricant oil to the groove (4). Feeding of the lubricant oil through the oil passage (5) to the groove (4) causes the valve seat surface (7) providing the part of the seat ring (6, 9) made of the porous material to contain lubricant oil. The lubricant oil thus contained produces a lubricant oil film on the valve seat surface (7), which prevents wear in the valve head and the valve seat surface.
