Patent number: 9343219Abstract: The present invention is directed to a reactor 1 including a combined product 10 made up of a coil member 2 and a magnetic core 3, and a case 4 storing the combined product 10. The case 4 is formed by a combination of a side wall portion 41 surrounding the combined product 10 and a bottom plate portion 40 being a member separate from the side wall portion 41. Between the bottom plate portion 40 of the case 4 and the coil member 2 (coils 2a and 2b), an insulating sheet 42 is interposed. In order to fabricate the reactor 1, the insulating sheet 42 is disposed on the bottom plate portion 40, and the combined product 10 is disposed on the insulating sheet 42. Then, the side wall portion 41 is disposed from above the combined product 10, and the side wall portion 41 and the bottom plate portion 40 are engaged with each other.Type: GrantFiled: March 14, 2012Date of Patent: May 17, 2016Assignees: Sumitomo Electric Industries, Ltd., Sumitomo Wiring Systems, Ltd.Inventors: Hajime Kawaguchi, Hideo Tawara, Takahiro Onizuka, Akinori Ooishi

Patent number: 7250755Abstract: A magnetic variation sensor includes a magneto-electricity conversion element for picking up variations in magnetic fields and converting the variations picked up into electric signals. A cable is connected to the magneto-electricity conversion element. The magneto-electricity conversion element and a portion of the cable where the cable is connected to the magneto-electricity conversion element are embedded in a resin shell. A mounting piece in the form of a metallic plate is secured to the shell with its portion embedded in the shell. The portion of the mounting piece embedded in the shell is formed with a hole through which the cable passes. The hole includes a radial recess formed along the outer circumference of the hole. The recess is filled with a portion of the resin forming the shell, whereby the resin filling the recess serves to prevent the mounting piece from rotating relative to the shell.Type: GrantFiled: December 10, 2004Date of Patent: July 31, 2007Assignee: Sumiden Electronics, Ltd.Inventor: Hideo Tawara

Patent number: 6454489Abstract: The NOx-cleaning paving structure of the present invention comprises a concrete base layer 1, a paving layer 2 and a surface layer 3 as illustrated in FIG. 1. The surface layer 3 comprises 100 parts by weight of cement, 5-50 parts by weight of titanium oxide powder and 100-700 parts by weight of aggregate, by which the surface layer on the paving layer can be provided with an NOx-cleaning action and an excellent durability. In addition, pozzolan materials, particularly a blast furnace slag, or adsorbing materials can be added to the surface layer. The paving layer 2 comprises an asphalt paving 21 or a concrete paving 6, both of which may include the used paving layers. It is preferable that the asphalt paving is porous and the surface thereof has an unevenness. Additionally, it is preferable that the thickness of the surface layer is 1-300 mm for the concrete paving and 2-15 mm for the asphalt paving. Among cement, injection cement for half-flexible paving is preferable.Type: GrantFiled: November 24, 1999Date of Patent: September 24, 2002Assignee: Mitsubishi Materials CorporationInventors: Yoshihiko Murata, Kiyoshi Kamitani, Hideo Tawara, Hiroshi Obata, Yutaka Yamada
