    摘要: A duplex transmission and reception system wherein a local oscillator of the receiver is dispensed with by using the output of a modulated transmission oscillator, with its modulation cancelled, in lieu of a receiver local oscillator. The transmitter modulation signal is adjusted by appropriate level correction and phase inversion. The modulated output of the transmission oscillator is itself applied to a modulator, where it is modulated by the adjusted modulation signal. This results in substantially cancelling out the modulation component of the transmission oscillator output. This modulation-cancelled signal is supplied to the mixer of a superheterodyne receiver as a local oscillator signal.

    摘要: A polishing apparatus is used for polishing a workpiece such as a semiconductor wafer to a flat mirror finish. The polishing apparatus comprises a turntable having a polishing surface, a top ring for holding a workpiece and pressing the workpiece against the polishing surface to polish the workpiece, at least three cleaning apparatuses for cleaning polished workpieces, and a transfer structure for transferring the polished workpieces between at least three cleaning apparatuses. The polishing apparatus further includes a rotary transporter disposed in a position which can be accessed by said top rings and having a plurality of portions positioned on a predetermined circumference from a center of rotation of the rotary transporter for holding the workpieces.
