Title: Cdma transmitter
Inventor: HAYASHI TATSUYA
IPC: H04B1/707
Filed: 2001-03-12
Abstract: PROBLEM TO BE SOLVED: To transmit only arbitrary channel transmission data from radio transmitting sections, even if all pieces of digital baseband transmission data are subjected simultaneously to radio transmission from the plurality of radio- transmitting sections. SOLUTION: Spread sections 23a to 23k multiply transmission data for each of N channels from separation sections 21a to 21k, by different spread codes allocated respectively for the channels to generate spread transmission data for each of the N channels which are spread directly. A selection section 25 inputs spread transmission data of all the inputted channels to one or two addition sections, selected arbitrarily from addition sections 27a to 27k. For example, when digital baseband transmission data for transmitting spread transmission data of all the channels from one radio transmission section is generated through addition, the addition sections 27a to 27k output and transmit the data to one of radio transmission sections 30a to 30k.

Title: Manufacturing method of semiconductor wafer
Inventor: HARADA SEISHI
IPC: H01L21/304
Filed: 2001-03-28
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of a semiconductor wafer making a processing damage of a chamfered part of the semiconductor wafer uniform. SOLUTION: At the time of finishing chamfering, a chamfering is carried out such that a chamfering processing direction of the silicon wafer W is perpendicular to a chamfering processing direction at the time of primary chamfering. As a result, a polishing streak to a circumferential direction of the wafer generated on the chamfered surface at the time of the primary chamfering is removed by the finishing chamfering. During the finishing chamfering, the wafer W and a finishing chamfering grinding wheel 20 are not intruded into a groove of a grinding wheel as a conventional method. Accordingly, even if an impact force during chamfering is applied to the finishing chamfering grinding wheel 20, the chamfering grinding wheel 20 outwardly escapes within a predetermined permission range.  As a result, an impact at the time of contact of a polishing applying surface of the chamfering grinding wheel 20 with the chamfering surface of the wafer W becomes small, a generation of polishing streak is inhibited and a damage of the chamfered part is made uniform.
