Abstract: On ending communication, a timer is started in order to watch a communication stop time interval. On staring the next communication, a timer value of the timer is watched. If the timer value is less than a communication stop time interval threshold value, a cell search processing is carried out by using a cell search result on previous communication. By monitoring a communication stop time interval and by using a previous cell search result in the manner described above, a cell search circuit has an important function which realizes a high-speed cell search in the same sector (the same cell) on continuous communications and decreasing of a consumed power.

Abstract: In manufacturing thinned semiconductor chips by grinding a semiconductor wafer supported on a rigid support substrate, in order to remove semiconductor wafer or semiconductor chips from the support substrate without damage to the semiconductor wafer or semiconductor chips, a semiconductor wafer at its surface is bonded on a light-transmissive support substrate through an adhesive layer having an adhesion force to reduce upon exposed to light radiation, thereby exposing the back surface of the semiconductor wafer. A tape is bonded to the backside of the semiconductor wafer integrated with the support substrate of after grinding, wherein the tape is supported at the periphery. Before or after bonding of the tape, light radiation is applied to the adhesive layer at a side close to the support substrate to reduce the adhesion force in the adhesion layer.

Abstract: A path searching circuit is provided which is capable of searching a stable path. A power delay profile calculated by a powering section using an I component correlation value and a Q component correlation value is input to a power level change monitoring section, where a change in a power level is monitored at a sampling point for each of two or more delay profiles to be used for same power adding processing. With correct signal receiving path timing, stable high correlation values are observed, that is, it is observed that the received power level is small in change. On the other hand, with instantaneously high correlation values caused by noises, it is observed that the received power level is great in change. As a result, in the weighing coefficient controlling section, a weighing coefficient for correlation values providing a great change in a received power level is determined so that the received power level becomes low when power is added and so that weighing control is exercised.
