Patent number: 8991044Abstract: A method for inserting a wire into a contact pin utilizes a wire insertion tool. The wire insertion tool includes a first division block having a first wire insertion guide ditch forming plane where a first wire insertion guide ditch has been formed, a second division block having a second wire insertion guide ditch forming plane where a second wire insertion guide ditch has been formed, and a division block positioning guide. When the first and second division blocks are fitted together by fitting the first and second wire insertion guide ditch forming planes, the first and second wire insertion guide ditches form a wire insertion guide hole. The division block positioning guide guides one of the blocks linearly to the other block such that these planes approach each other or separate from each other.Type: GrantFiled: August 1, 2013Date of Patent: March 31, 2015Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Fumihito Soma, Minoru Majima, Yosuke Sasaki, Takuya Oshiba, Hiroaki Miyazawa, Takamitsu Hamanaga, Kentaro Nishi

Publication number: 20130312259Abstract: The wire insertion tool by the present invention includes: a first division block having a first wire insertion guide ditch forming plane where a first wire insertion guide ditch has been formed; a second division block having a second wire insertion guide ditch forming plane where a second wire insertion guide ditch has been formed; and a division block positioning guide. When the first division block and the second division block form a coupling unit by fitting the first wire insertion guide ditch forming plane and the second wire insertion guide ditch forming plane, the first wire insertion guide ditch and the second wire insertion guide ditch form a wire insertion guide hole. The division block positioning guide guides one of these blocks linearly to the other such that these planes approach to each other or separate from each other.Type: ApplicationFiled: August 1, 2013Publication date: November 28, 2013Applicant: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Fumihito SOMA, Minoru MAJIMA, Yosuke SASAKI, Takuya OSHIBA, Hiroaki MIYAZAWA, Takamitsu HAMANAGA, Kentaro NISHI

Patent number: 8399774Abstract: A substrate for suspension comprises a metallic substrate, an insulating layer formed on the metallic substrate, having an opening for grounding terminal, and a grounding conductor formed on the insulating layer. A grounding-terminal-forming material is placed in the opening for grounding terminal to form a grounding terminal that connects the metallic substrate and the grounding conductor. The grounding conductor does not surround a portion of the circumference of the opening for grounding terminal.Type: GrantFiled: November 23, 2011Date of Patent: March 19, 2013Assignee: Dai Nippon Printing Co., Ltd.Inventors: Yoichi Hitomi, Hiroaki Miyazawa, Shinji Kumon, Terutoshi Momose

Patent number: 8040634Abstract: A magnetic head suspension having a thin metallic plate as a substrate which is caused to have a new function besides a function as a spring. The magnetic head suspension plural lines for connecting a magnetic head and a control circuit board to each other are formed over a thin metallic plate having a spring property through an insulating layer, and are integrated with the thin metallic plate A metallic pad made of a same metal layer as the plural lines is formed independently of the lines, an opening is made in a portion of the metallic pad to penetrate the insulating layer and then to reach the thin metallic plate, and an electroconductive region is formed into the opening by metal plating, thereby connecting the metallic pad and the thin metallic plate electrically to each other.Type: GrantFiled: July 14, 2006Date of Patent: October 18, 2011Assignee: Dai Nippon Printing Co., Ltd.Inventors: Hiroaki Miyazawa, Terutoshi Momose, Yoichi Hitomi, Tsuyoshi Yamazaki
