Publication number: 20140091788Abstract: A current detector includes a magnetic core that is molded by sintering powder made from a magnetic material, and a current detection busbar. The current detection busbar is a conductor including a penetrating portion that penetrates a hole portion of the magnetic core in a first direction in which a current flows, and terminal portions that are in connection with the penetrating portion on both sides in the first direction. The width of the terminal portions is larger than the maximum width of the hole portion, and the minimum width of the cross-sectional contour of the penetrating portion is larger than the thickness of the terminal portions. An insulating casing holds the magnetic core, the current detection busbar, and the Hall element, while keeping them from coming into contact with each other.Type: ApplicationFiled: April 5, 2012Publication date: April 3, 2014Applicants: AUTONETWORKS TECHNOLOGIES, LTD., SUMITOMO ELECTRIC INDUSTRIES, LTD., SUMITOMO WIRING SYSTEMS, LTD.Inventors: Takashi Misaki, Kouji Nishi, Hirokatsu Nakajima, Susumu Fukuyama

Publication number: 20140084914Abstract: In a current detection device for detecting current in a busbar, a reduction in device size may be realized by employing a small magnetic core. The prevention or reduction of excessive heat generation by the busbar, the facilitation of the attachment task, and a reduction in the amount of space required for the attachment task may also be realized. The folded-back busbar is U-shaped with a bar-shaped penetration portion that passes through a hole portion of a magnetic core, two bar-shaped extension portions, and two flat plate-shaped penetration portions. The width of each terminal portion is larger than the widths of the penetration portion and the extension portions. An insulating casing supports the magnetic core, a Hall element, and the folded-back busbar in a fixed positional relationship, with the two terminal portions being exposed to the outside.Type: ApplicationFiled: October 24, 2011Publication date: March 27, 2014Applicants: AUTONETWORKS TECHNOLOGIES, LTD., SUMITOMO ELECTRIC INDUSTRIES, LTD., SUMITOMO WIRING SYSTEMS, LTD.Inventors: Hirokatsu Nakajima, Satoru Chaen, Kouji Nishi, Takashi Misaki

Publication number: 20070235077Abstract: In a solar cell module, a solder fillet 19 is formed on an end surface on the shorter length side of a connection tab to be connected to a bus bar electrode 2a, 3a up to the height of the connection tab. The geometry of the solder fillet 19 is adjusted so that an indentation amount is 0-54% of the height or a bulge amount is 0-10% of the height, by which the maximum principal stress generated during the manufacturing process of a solar cell element 4 can be reduced, and therefore occurrences of cracks can be reduced. Also during a laminating process, breaking of the solar cell element or crack generation can be eliminated.Type: ApplicationFiled: March 26, 2007Publication date: October 11, 2007Applicant: KYOCERA CORPORATIONInventors: Masaru NAGATA, Toshifumi KIYOHARA, Kouji NISHI

Patent number: 6765601Abstract: A thermal printhead is disclosed which prevents an undesired color from being generated around the periphery of a desired color, even when a two-color thermo-sensitive paper is used as the recording medium. A plurality of variable electric potential regions are formed on top of a heating resistor. Each region is disposed between two adjacent projections, and has an individual electrode that intersects therewith. The variable electric potential regions generate colors due to electric potential differences that are produced between a common electrode and individual electrodes. The width of each variable electric potential region corresponds to one dot, and is set such that the temperature of the entire region is substantially uniform when heated. A plurality of fixed electric potential regions are formed on top of the heating resistor, and each region has a fixed electric potential even when an electric potential difference is produced between the common electrode and the individual electrodes.Type: GrantFiled: February 17, 2003Date of Patent: July 20, 2004Assignee: Rohm Co., Ltd.Inventors: Kouji Nishi, Takaya Nagahata

Patent number: 5729330Abstract: A magnet is provided on either a negative film mask or a negative film mask table of a negative film mask apparatus, and a magnetic material is provided on the other of these. When the negative film mask in which a negative film has been loaded is placed on the negative film mask table, the negative film mask is held in place by a magnetic force. The negative film mask apparatus is provided with a stopper. The stopper is adapted to press a closely-contacting member against a sliding surface of the negative film mask table when necessary, thereby preventing the negative film mask from sliding. The closely-contacting member is made of a material such as rubber so that it can closely contact a sliding surface of the negative film mask table. Further, a magnetic member is included in the stopper. The stopper generates a large frictional force utilizing pressing force and magnetic force.Type: GrantFiled: January 19, 1996Date of Patent: March 17, 1998Assignee: Noritsu Koki Co., Ltd.Inventors: Kouji Nishi, Mitsuhiko Itojima
