Patent number: 7671608Abstract: An electrical junction box is adapted to be set in a conductivity inspection device. The conductivity inspection device includes a sensing pin assembly and guide pins, the guide pins extending beyond the sensing pin assembly. The electrical junction box includes a casing including a containing section and at least two guide holes formed in a surface wall of the casing, the guide holes being spaced away from each other by a given distance.

Patent number: 7508626Abstract: The present invention provides a thin film magnetic head in which a magnetic domain structure of a magnetic pole layer is controlled and fluctuation in recording magnetization caused by leaked magnetic flux generated by unintentional shift of a magnetic domain wall can be prevented. When a length of a front end portion of a magnetic pole part layer, which specifies a recording track width of a recording medium, is set as D, and a width of an upper edge of a magnetic pole end surface, positioned on a medium outflow side, is set as W, a dimensional ratio D/W of the length D to the width W is set so as to lie within the range of 0<D/W?2.3. Since magnetic domain stability of the magnetic pole part layer is assured on the basis of the proper formation of the shape of the front end portion, leak of magnetic flux from the front end portion immediately after recording is suppressed. Therefore, occurrence of an inconvenience such as unintended erasure of information caused by the leaked magnetic flux is prevented.Type: GrantFiled: November 25, 2003Date of Patent: March 24, 2009Assignees: TDK Corporation, SAE Magnetics (H.K.)

Patent number: 7328499Abstract: Provided is a thin film magnetic head capable of inhibiting the occurrence of track erasing and improving the reliability of magnetic recording. Two taper surfaces are disposed on both sides of a return yoke layer. As no corner portion which may induce concentration of a magnetic flux exists on the both sides of the return yoke layer, even if the magnetic flux emitted from a pole layer is returned to the return yoke layer through a hard disk, a magnetic field strength is not locally and pronouncedly concentrated in proximity to the taper surfaces of the return yoke layer. Thereby, the concentration of the magnetic flux can be prevented, and the probability of the occurrence of unnecessary recording decreases, so the occurrence of track erasing can be inhibited, and the reliability of magnetic recording can be improved.Type: GrantFiled: January 17, 2006Date of Patent: February 12, 2008Assignees: TDK Corporation, SAE Magnetics (H.K.)

Publication number: 20070273846Abstract: A video projector (1) comprises a projection lens (18) which projects an image on a screen (S), a zoom ring (19) which varies a magnification ratio of the projection lens (18), a drive wheel (32) which is partially protruded from a bottom face of a housing (2), and a plurality of gears (310, 311, 312) that constitutes a power transmission mechanism (31) between the drive wheel (32) and the zoom ring (19). When the video projector (1) is moved in an anteroposterior direction to the screen with rotating the drive wheel (32), the zoom ring (19) is turned in conjunction with the rotation of the drive wheel (32) through the power transmission mechanism (31). Since the magnification ratio of the projection lens (18) is varied with the turning of the zoom ring (19), the size of the image projected on the screen is varied without a direct operation of the zoom ring (19) by a user.Type: ApplicationFiled: May 24, 2007Publication date: November 29, 2007Applicant: Funai Electric Co., Ltd.Inventor: Akihiro Oda

Patent number: 7206166Abstract: Provided is a thin film magnetic head which enables both ensuring overwrite characteristics and preventing an adverse effect resulting from side erase, such as degradation in an output signal. An exposed surface of a magnetic pole portion layer is configured to have the shape of an asymmetric inverted trapezoid corresponding to a remaining region which remains after removing a width increasing region in the shape of a right triangle from a rectangular region on the side of a side edge. The side edge of the exposed surface is caused to correspond to the side on which a magnetic flux emitted from the magnetic pole portion layer onto a target track of a hard disk causes information to unintentionally overwrite existing information recorded on an adjacent track. This configuration allows preventing the exposed surface from extending to the adjacent track, thus preventing the adverse effect resulting from side erase.Type: GrantFiled: August 12, 2003Date of Patent: April 17, 2007Assignee: TDK CorporationInventors: Yasuyuki Notsuke, Akihiro Oda, Tetsuya Roppongi
