Publication number: 20100302662Abstract: A testing method of a wafer provided with a plurality of thin-film magnetic heads is provided. Each of the plurality of thin-film magnetic heads includes a main pole layer, a first test pad formed on the wafer and electrically connected with an extended top end section of the main pole layer and a second test pad formed on the wafer and electrically connected with a back end section of the main pole layer. The testing method includes a step of measuring an electrical resistance between the first test pad and the second test pad, a step of judging whether the measured electrical resistance is within a set range, and a step of discriminating that the thin-film magnetic head is a non-defective product when the measured electrical resistance is within the set range.Type: ApplicationFiled: May 28, 2009Publication date: December 2, 2010Applicant: TDK CORPORATIONInventors: Isamu TOBA, Yasuhiro HASEGAWA, Koichi OTANI, Takamitsu SAKAMOTO

Publication number: 20100220710Abstract: A multicarrier transmitting apparatus capable of providing a fast cell search. A base station apparatus (100), which serves as a multicarrier transmitting apparatus for transmitting frames each including, as synchronization channel sequences, first synchronization sequences (P-SCH sequence) used for timing determinations and second synchronization sequences (S-SCH sequence) different from the first synchronization sequences, comprises a frame forming part (130) that forms frames each including the first synchronization sequence (P-SCH sequence) disposed in each of subcarriers symmetrical with respect to a DC component subcarrier (DC subcarrier) in the frequency direction; and an RF transmitting part (160) that transmits the frames. In this way, a frame receiving end can use a filter having a polarly symmetrical pass-band and needs no frequency shifting process, with the result that the processing amount at the receiving end can be reduced and hence a fast cell search can be achieved.Type: ApplicationFiled: September 8, 2006Publication date: September 2, 2010Applicant: PANASONIC CORPORATIONInventors: Tomohiro Sugawara, Yasuhiro Hasegawa

Publication number: 20100151803Abstract: A multi-carrier transmission device improves peak suppression efficiency in a multi-carrier signal. The multi-carrier transmission device (100) has a peak suppression unit (140) for dividing a multi-carrier signal into two parts: a first multi-carrier signal and a second multi-carrier signal. A peak signal detection unit (142) detects a power value at a predetermined interval concerning the first multi-carrier signal. When the detected power value is equal to or above a predetermined level, a peak extraction unit (144) extracts a signal component equal to or above the predetermined level from the first multi-carrier signal. A band limit filter unit (146) passes only a predetermined band from the extracted signal component. An adder (154) subtracts the signal component after the band limit from the second multi-carrier signal.Type: ApplicationFiled: October 6, 2005Publication date: June 17, 2010Applicant: MATSUSHITA ELECTRIC INDUSTRIAL CO., LTD.Inventors: Yuta Seki, Yasuhiro Hasegawa, Shinji Ueda

Publication number: 20040166808Abstract: An amplitude-phase information acquiring section 105 acquires information indicating variation in amplitude and phase, using a probe signal that suffers the same variation in amplitude and phase as a communication traffic signal received by antennas suffers, between each antenna and the amplitude-phase information acquiring section 105. A received power measuring section 106 measures the received power of the communication traffic signal and the probe signal. A correction value control section 107 adaptively determines, based on the amplitude-phase information and the received power, a correction value for correcting for the variation of the amplitude and phase of the communication traffic signal. A correcting section 108, for each antenna, corrects for the variation of the amplitude and phase of the communication traffic signal by using the correction value determined based on the received power.Type: ApplicationFiled: December 11, 2003Publication date: August 26, 2004Inventors: Yasuhiro Hasegawa, Keiji Takakusaki
