Publication number: 20060163499Abstract: An electron beam irradiation apparatus includes an electron beam emission section having an electron beam irradiating tube that emits an electron beam; an electron beam irradiation section for irradiating the emitted electron beam to a target; a transfer mechanism for transferring the target to the electron beam irradiation section; a rotation mechanism for rotating the target on its own axis when irradiating the electron beam; and a linear movement mechanism for generating a relative linear movement such that the electron beam irradiating tube passes right above the target, between the target and the electron beam irradiating tube, when irradiating the electron beam. The linear movement mechanism generates a relative linear movement such that the electron beam irradiating tube goes from an end portion of the target toward the center of the target and turns back before the center of the electron beam emitting portion of the electron beam irradiating tube reaches the center of the target.Type: ApplicationFiled: January 24, 2006Publication date: July 27, 2006Applicants: Toyo Ink Manufacturing Co., Ltd., TDK CorporationInventors: Naoyuki Echigo, Yo Marui, Yoshihiro Fuse, Mamoru Usami, Kazushi Tanaka, Minao Himeno, Yukio Kaneko

Patent number: 5309253Abstract: A picture element conversion system consists of a simple electric circuit for reducing or enlarging an image at high quality. The system includes a cumulative adding unit for cumulatively adding a multiplying factor, in synchronization with clock signals, and outputting the added data and a carry signal. A contiguous picture element output unit temporarily holds a picture element data array along one of two scanning directions and outputs at least two contiguous picture element data. A typical value calculation unit divides a section defined by the contiguous picture element data into sub-sections and obtains typical values corresponding to each sub-section from the picture element data output from the contiguous picture element output unit.Type: GrantFiled: March 29, 1991Date of Patent: May 3, 1994Assignee: Seiko Instruments Inc.Inventors: Toru Ariga, Naoyuki Echigo

Patent number: 4306170Abstract: An AT-cut quartz resonator is disclosed, wherein the length l, the width w and the thickness t of the quartz crystal plate are respectively chosen in the directions of an electrical axis (X-axis), an optical axis (Z'-axis) and a mechanical axis (Y'-axis), the width-to-thickness ratio w/t is chosen in the range of 2.0 to 2.8 and the length-to-thickness ratio l/t is chosen less than 25. Consequently, an AT-cut quartz resonator of miniature size having high Q-values of the major mode and excellent frequency-temperature characteristics of the vibration frequency is realized.Type: GrantFiled: August 27, 1979Date of Patent: December 15, 1981Assignee: Kabushiki Kaisha Daini SeikoshaInventors: Shunichi Motte, Naoyuki Echigo, Shiro Yamashita, Tsuneo Kuwabara, Kunihiro Takahashi
