    摘要: A polishing apparatus is provided which can effect surface-based polishing of a wafer without causing the wafer to produce an undulation or peripheral protrusion. A sheetlike polishing member 5 constructed by superposing a foam sheet 2 containing minute closed cells in a web of chloroprene rubber and a velour type non-woven fabric (polishing cloth 3) is attached fast to the surface of a polishing table 1. The polishing member is capable of polishing a given wafer while maintaining the uniformity of thickness of the wafer or an oxide film formed on the surface of the wafer because, during the application of pressure by a pressing member 14, the polishing pressure is uniformly distributed throughout the entire rear surface of the wafer and the polishing member is bent in conformity with the global rises and falls in the wafer surface.

    摘要: Provided are a radio communication system, a receiver, and a transmitter, which are capable of reducing an operation time period of a reception circuit of the receiver and achieving reduction in power consumption even if there is a clock error between the transmitter and the receiver. In a case of a conventional method illustrated in FIG. 1(A), the receiver is operated earlier by a time period (Tm), to thereby achieve synchronization before the clock error of the receiver exceeds the time period (Tm). This requires an extended reception time period for achieving clock synchronization, which therefore prevents the receiver from reducing its power consumption. In view of this, according to the present invention, as illustrated in FIG. 1(B), a synchronization signal is continuously transmitted from the transmitter a plurality of times in a short period of time, and the receiver receives only one of the continuously-transmitted synchronization signals. With this, the receiver can achieve synchronization of a reference clock by starting a reception operation earlier only by a time period (Tm′) (Tm′≦Tm).
