Patent number: 7339386Abstract: A probe is mountable to a printed circuit board testing device which performs a test on a predetermined land and/or a predetermined via hole of a printed circuit board. The probe includes a probe tip and a protrusion. The probe tip is contactable with the land and/or the via hole and projectable from the probe. The protrusion is disposed at a surface of the probe, the surface of the probe being disposed opposite to where the probe tip is projectable. The protrusion is grounded by a reaction pressure that is generated when the probe tip contacts the land and/or the via hole.Type: GrantFiled: November 30, 2005Date of Patent: March 4, 2008Assignee: Fujitsu LimitedInventors: Susumu Miyazawa, Mikio Hara, Syuji Kagiyama, Yasuo Mori, Kyosuke Yoshizu, Shigenori Makita, Yoshino Miyazawa

Publication number: 20080008381Abstract: The present invention has been made to obtain a coordinate acquisition apparatus for test of a printed board that can automatically generate coordinates required for performing the clip test from a predetermined target object formed in a printed board to thereby automate the clip test. A coordinate acquisition apparatus for test of a printed board comprises: a camera that photographs a printed board; a target object detection section that uses pattern matching to detect a predetermined target object formed in the printed board from image data photographed by the camera; and a coordinate position acquisition section that acquires the coordinate position of the target object detected by the target object detection section with respect to the printed board.Type: ApplicationFiled: October 27, 2006Publication date: January 10, 2008Applicant: FUJITSU LIMITEDInventors: Yasunori Ushio, Mikio Hara, Yoshiko Yamaguchi

Patent number: 6711891Abstract: The air-fuel ratio of an air-fuel mixture to be combusted in an internal combustion engine 1 is manipulated to converge an output VO2/out of an O2 sensor 6 which is disposed downstream of a catalytic converter 3 to a target value VO2/TARGET depending on an operating state of the internal combustion engine 1, while at the same time a deterioration evaluating parameter is determined from time-series data of the output VO2/out of the O2 sensor 6. The value of the deterioration evaluating parameter is corrected depending on an average value of the output VO2/out of the O2 sensor 6 or the target value VO2/TARGET, and the deteriorated state of the catalytic converter 3 is evaluated based on the corrected value of the deterioration evaluating parameter.Type: GrantFiled: May 13, 2002Date of Patent: March 30, 2004Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Toru Kitamura, Hideki Uedahira, Mikio Hara
