Patent number: 6582763Abstract: The oxide coated fine metal particles include fine core metal particles that are covered with a coating layer including an oxygen-containing compound of a dissimilar element that do not contain as a main component a metal element which is the main component of the fine core metal particles, or a complex oxide or a complex salt of the oxide, the complex oxide or the oxy-acid salt and an oxide of the metal element. A metal powder material is mixed with an oxide powder material of the oxygen-containing compound to obtain a powder material mixture. The powder material mixture is supplied into a thermal plasma to make a vapor-phase mixture and then the vapor-phase mixture is quenched to form the oxide coated fine metal particles comprising the fine core metal particles that are finer than the metal powder material and which are covered with the coating layer including the oxygen-containing compound.Type: GrantFiled: January 31, 2000Date of Patent: June 24, 2003Assignees: Nisshin Seifun Group Inc., Nisshin Engineering Inc.Inventors: Keiichi Nishimura, Takashi Fujii, Kazuhiro Yubuta, Sadao Shinozaki

Patent number: 6578381Abstract: The oxides-enclosed fine glass particles are arranged such that two or more pieces of at least two kinds of enclosing particles, which comprise oxides, double oxides, or salts of oxyacids, or double oxides or double salts thereof, are enclosed in each of the fine glass particles. The fine particles can be easily manufactured by mixing a powder material of glass with a powder material of oxides which comprise oxides, double oxides, or salts of oxyacids, or double oxides or double salts thereof that are not made to glass; converting the thus obtained mixture of the materials into a mixture in a vapor-state by supplying the thermal plasma thereto; and quickly cooling the mixture in the vapor-state. Highly-scattered fine particles of oxides can be easily obtained from the fine particles, and thus a plurality of kinds of fine particles of oxides can be evenly and uniformly mixed in a small amount with a mother material without being unevenly scattered.Type: GrantFiled: December 20, 2001Date of Patent: June 17, 2003Assignees: Nisshin Seifun Group Inc., Nisshin Engineering Inc.Inventors: Keiichi Nishimura, Takashi Fujii, Kazuhiro Yubuta, Sadao Shinozaki

Patent number: 6428457Abstract: A former for forming an elongated planar bag-making material into a tubular form is composed of a hollow cylindrical tubular part and a shoulder part which has a planar guide section and is connected to the tubular part along a connecting line surrounding the tubular part. Both the tubular and shoulder parts are formed by cutting a tube-forming piece and a shoulder-forming piece from a flat blank sheet in appropriate shapes and bending these pieces into the shapes of the tubular and shoulder parts. The connecting line is designed such that the angle between its tangent and the axial direction of the tubular part changes at a constant rate. Portions of the edges of the tube-forming and shoulder-forming pieces may be in a shape of a parabola or a hyperbolic function curve, and these pieces are obtained by making a numerical control program from the desired shapes of the curve and controlling a laser cutter by the program to cut a blank sheet in the desired shapes.Type: GrantFiled: September 29, 1995Date of Patent: August 6, 2002Assignee: Ishida Co., Ltd.Inventors: Masao Fukuda, Keiichi Nishimura

Patent number: 6241094Abstract: An object of the present invention consists in providing a new spool case in which the stored spool can be held without contacting with it by hand, engaging or disengaging of the spool in respect to the bonding device can be carried out without having any relation with a length of the holder or presence or non-presence of an engaging means, a reliability in holding the spool is high and a spool held state can be easily maintained. In addition, solving means of the present invention can be handled such that the spool is held by the engaging pieces 7 arranged at the base 3 and the spool is not directly contacted with hand. The spool held state is maintained by the resilient engaging force of each of the engaging pieces 7 and this is not released so long as each of these engaging pieces 7 is not resiliently deformed and is not released from the flange.Type: GrantFiled: August 7, 1998Date of Patent: June 5, 2001Assignee: Tanaka Denshi Kogyo Kabushiki KaishaInventors: Tadao Anjo, Osamu Sato, Toshio Kaji, Keiichi Nishimura

Patent number: 5054134Abstract: In a circulating pool main body which defines a swimming pool or tank, a bottom partition wall and front and rear curved partition walls are disposed and spaced apart by a suitable distance from the bottom and the front and rear curved portions of the main body, thereby defining a water circulation passage having an outlet opening to an upper upstream end of the swimming tank or pool and an inlet at the upper downstream end of the swimming tank or pool so that only the upper water layer of the body of water in the swimming tank or pool is forced to flow. Furthermore, one or more swingable blades or vanes are attached to the outlet of the water circulation passage so that the flow rate of the flowing upper water layer in the swimming tank or pool and its direction may be varied.Type: GrantFiled: July 30, 1990Date of Patent: October 8, 1991Assignee: Ishikawajima-Harima Jukogyo Kabushiki KaishaInventors: Osamu Teratsuji, Keiichi Nishimura, Yoshiro Moriya, Yukihiko Ueda
