Patent number: 7938883Abstract: A method of making metallic iron in which a compact, containing iron oxide such as iron ore or the like and a carbonaceous reductant such as coal or the like, is used as material, and the iron oxide is reduced through the application of heat, thereby making metallic iron. In the course of this reduction, a shell composed of metallic iron is generated and grown on the surface of the compact, and slag aggregates inside the shell. This reduction continues until substantially no iron oxide is present within the metallic iron shell. Subsequently, heating is further performed to melt the metallic iron and slag. Molten metallic iron and molten slag are separated one from the other, thereby obtaining metallic iron with a relatively high metallization ratio.Type: GrantFiled: September 14, 2007Date of Patent: May 10, 2011Assignee: Kabushiki Kaisha Kobe Seiko ShoInventors: Takuya Negami, Kazuo Kunii, Shinichi Inaba, Masataka Shimizu, Isao Kobayashi, Yoshimichi Takenaka, Toshihide Matsumura, Akira Uragami, Takashi Kujirai, Osamu Tsuchiya, Kimio Sugiyama, Shuzo Ito, Shoichi Kikuchi

Patent number: 6301757Abstract: A buckle comprises a male member and a female member. The male member is provided with an insertion portion adapted to be inserted into the female member and an insertion hole formed inside of the insertion portion. The female member is provided with a recess in which the insertion portion is to be fitted, and an accommodating portion adapted to communicate with the insertion hole. The accommodating portion is provided therein with an engaging piece swingable in an inserting direction to the insertion hole. The engaging piece is provided with an engaging portion which is to be inserted through the insertion hole. The insertion hole of the male member is formed with a locking surface against which the engaging portion is adapted to abut.Type: GrantFiled: December 10, 1999Date of Patent: October 16, 2001Assignee: YKK CorporationInventors: Kazuo Kunii, Tomohisa Ishida

Patent number: 5343610Abstract: A method for making an anti-skid apparatus for an automobile tire includes coating a plurality of core materials with rubber to form a plurality of cords; placing the cords in grooves of a preliminary molding plate and knitting the cords to form a net body; molding the cord into a non-vulcanized net body which inherently possesses crossing sections-where one of the plurality of cords lies on top of another of the plurality of cords; pressing the crossing sections so as to cause the core materials at the crossing sections to become linearly aligned; and vulcanizing the pressed non-vulcanized anti-skid net bodies to form a vulcanized net body. The step of pressing the crossing sections temporarily fixes the respective cords to each other at respective crossing sections. Also, affixing elements are attached to the vulcanized net body to detachably secure the vulcanized net body to an automobile tire.Type: GrantFiled: May 14, 1993Date of Patent: September 6, 1994Assignee: Okamoto Industries, Inc.Inventors: Osamu Haruda, Shin Imamura, Suguru Hanzawa, Nobuo Amada, Kazuo Kunii, Hidetaka Kobayashi, Shinichi Yano, Muneo Nishiyama

Patent number: 5247980Abstract: An anti-skid net body for a tire includes a plurality of cords having crossing portions and open portions, with the crossing portions having a flat shape. At least one rope is fixed to an inside portion of the net body. An actional band and a setting band are detachably connected to an outside portion of the net body, wherein the setting band is connected prior to connecting the actional band, thereby tightly fastening the anti-skid net body to a tire.Type: GrantFiled: April 5, 1990Date of Patent: September 28, 1993Assignee: Okamoto Industries, Inc.Inventors: Osamu Haruda, Shin Imamura, Suguru Hanzawa, Nobuo Amada, Kazuo Kunii, Hidetaka Kobayashi, Shinichi Yano, Muneo Nishiyama
