Patent number: 9824867Abstract: Provided is a plasma generation apparatus capable of generating uniform plasma over a wide range. The plasma generation apparatus includes two oppositely arranged plasma guns each injecting a discharge gas to be ionized, and having a cathode for emitting electrons, and a converging coil for forming a magnetic flux to guide the emitted electrons, and polarities of the converging coils with respect to the cathodes in the two plasma guns are opposite to each other.Type: GrantFiled: February 27, 2013Date of Patent: November 21, 2017Assignee: CHUGAI RO CO., LTD.Inventor: Eiji Furuya

Patent number: 9199413Abstract: In this method for producing an ornament (1), wherein an ornamental sheet (3) is bonded/affixed by means of a vacuum-press-bonding method to the convex front surface (21) of a substrate (2) provided with a convex front surface (21) and a concave back surface (22), a work-support base (6) is placed on a work placement surface (121a) formed on the upper surface of the suction chamber (120) of a vacuum-press-bonding device (100), and the substrate (2) is positioned by fitting an engagement protrusion (28) formed on the back surface of the substrate (2) covered by the ornamental sheet (3) to an engagement hole (68) at the work-support surface (61) formed on the upper surface of the work-support base (6). When bonding/affixing the ornamental sheet (3) to the substrate (2) by means of the vacuum-press-bonding device (100), position deviation of the substrate (2) is prevented by the engagement of the engagement hole (68) and the engagement protrusion (28).Type: GrantFiled: October 31, 2011Date of Patent: December 1, 2015Assignee: FUJIGEN INC.Inventors: Eiji Furuya, Kei Komatsu, Kazutaka Ono

Patent number: 6089186Abstract: The invention provides a vacuum coating forming device for forming a thin-film coating by a plasma beam on a substrate arranged in a vacuum chamber, the vacuum coating forming device being provided with a pressure gradient type plasma gun for generating the plasma beam toward the vacuum chamber and a converging coil which is provided so as to surround a short-tube portion of the vacuum chamber projecting toward an outlet of the plasma gun and which reduces a cross section of the plasma beam. This vacuum coating forming device further comprises an insulating tube provided at the outlet so as to surround the plasma beam and project in electric floating state, and an electron return electrode which surrounds the insulating tube within the short-tube portion and which is higher in electric potential than the outlet.Type: GrantFiled: September 13, 1999Date of Patent: July 18, 2000Assignees: Chugai Ro Co., Ltd., Dai Nippon Printing Co., Ltd.Inventors: Kinya Kisoda, Eiji Furuya, Ryoichi Ohigashi
