Patent number: 8911249Abstract: A connection cable includes a cable-side connector, a cable body, a cover member, and a locking member. The cover member is configured to define a gap between the cable-side connector and the cover member such that a bulb-side connector is fitted to the gap when the cable-side connector is connected to the bulb-side connector. The locking member includes a slide portion arranged to slide along an outer circumferential surface of the cover member. The slide portion is provided with a protrusion extending through the cover member and engaging with a locking hole formed in the bulb-side connector. The slide portion is configured such that, when the slide portion is caused to slide, the protrusion is moved away from the cable-side connector and disengaged from the locking hole.Type: GrantFiled: January 23, 2013Date of Patent: December 16, 2014Assignee: Panasonic CorporationInventor: Kenichi Takamatsu

Patent number: 7394340Abstract: An electromagnetic device and a high-voltage generating device which are thin and improved in the characteristics are provided in which a magnetic core is made of a cylindrical form of a ferrite material having a higher intrinsic resistance. A winding is provided by winding a flat rectangular wire conductor in an edge-wise winding form directly on substantially the entire length of the magnetic core. As any insulator such as a coil bobbin is not needed between the flat rectangular wire conductor and the magnetic core, the winding can be decreased in the overall size or thickness thus contributing to the dimensional reduction of the electromagnetic device. Also, as its flat rectangular wire conductor is wound directly on the magnetic core, the winding can be minimized in the length and thus the overall resistance. Moreover, as there is no gap between the winding and the magnetic core, the self-inductance can be reduced while the size and the number of turns of the winding remain unchanged.Type: GrantFiled: October 11, 2006Date of Patent: July 1, 2008Assignee: Matsushita Electric Works, Ltd.Inventors: Hidenori Kakehashi, Takashi Kanbara, Toru Fujiwara, Kenichi Takamatsu, Tomoyuki Nakano, Kazuhiko Kinutant, Takaaki Chuzawa, Masaki Satou, Takao Miyai
