Patent number: 9773973Abstract: A production process in which in an element isolation process for a magnetoresistive effect element, a re-deposited film adhered to a side wall of the element is efficiently removed by ion beam etching. Ion beam etching is performed while a substrate located being inclined relative to the grid is rotated. In the ion beam etching, an energy amount of an ion beam entering from a direction in which a pattern groove formed on the substrate extends is increased larger than the energy amount of the ion beam entering from another direction by controlling a rotation speed of the substrate, and the re-deposited film adhered to the side wall of the magnetoresistive effect element formed on the substrate is efficiently removed by etching.Type: GrantFiled: November 14, 2013Date of Patent: September 26, 2017Assignee: CANON ANELVA CORPORATIONInventors: Yoshimitsu Kodaira, Isao Takeuchi, Mihoko Nakamura

Patent number: 6408038Abstract: A receiving apparatus receives a digital broadcast signal having been modulated in an orthogonal frequency multiplexing method of which data of each frame is composed of a synchronous reference signal and transmission data and of which data is assigned to a plurality of carriers that are orthogonal to each other. A synchronous TFPR signal is transmitted every frame. An AFC (automatic frequency control) circuit receives the synchronous TFPR signal, and obtains a frequency error and a timing error of the received signal to control the frequency and the timing. To remove an influence of a multi-path to the synchronous TFPR signal, an equalizer is disposed. The influence of the multi-path to the synchronous TFPR signal is removed by the equalizer. Thus, the frequency and the timing of a carrier of the receiver side can be exactly controlled.Type: GrantFiled: January 8, 1999Date of Patent: June 18, 2002Assignee: Sony CorporationInventor: Isao Takeuchi

Publication number: 20020058487Abstract: A radio wave that will act as an interference wave is received together with a desired wave. A phase locking section produces a phase-locked signal that is phase-locked at the frequency of the interference wave. A level adjusting section adjusts the level of the phase-locked signal and supplies the level-adjusted, phase-locked signal to a subtracter, whereby the interference wave component is eliminated from the desired wave. The desired wave from which the interference wave component is eliminated is fed back to the level adjusting section.Type: ApplicationFiled: May 22, 2001Publication date: May 16, 2002Inventor: Isao Takeuchi
