Publication number: 20120149285Abstract: A structure for deburring a ball is provided. The structure includes an arm, a gear structure for changing the effective length of the arm, and a cam structure for changing the effective angular position of the arm. A finger having an abrasive surface reciprocates on the arm. A ball is placed in a rotating holder and positioned in effective position for the abrasive surface to contact and remove at least one burr on the ball.Type: ApplicationFiled: December 14, 2010Publication date: June 14, 2012Applicant: Nike, Inc.Inventor: Takahisa Ono

Patent number: 7685855Abstract: A vertically oscillating working device 2 has a body to be oscillated 23 having an inner space that is formed by a cover member 21 and a vehicle wheel 22, which is a body to be worked, and receives working materials 25 in it and also has oscillating means for vertically oscillating the body to be oscillated 23. The working materials 25 are allowed to collide with the vehicle wheel 22 by the oscillation, and thereby the vehicle wheel 22 is worked. With the working device 2, a casting can be oscillated together with hardening materials, and excellent mechanical properties can be uniformly added to a predetermined portion of the casting by the oscillation without changing the position of the casting.Type: GrantFiled: March 30, 2007Date of Patent: March 30, 2010Assignee: Asahi Tec CorporationInventors: Matsuo Suzuki, Shinichirou Azuma, Takayuki Sakai, Kiyomi Hagita, Atsurou Yamamoto

Patent number: 7458881Abstract: There is provided a surface treated product that moves relatively in a fluid, wherein a surface of the surface treated product has continuous dimples, each dimple having a diameter of 10 to 2500 ?m and a depth of 50 ?m or less. The surface treated product significantly reduces resistance of a fluid to an object in the fluid, and significantly improves a flow state of the fluid.Type: GrantFiled: March 8, 2006Date of Patent: December 2, 2008Assignee: Asahi Tec CorporationInventors: Shiro Kawashima, Hiromi Akihori, Matuo Suzuki, Hidekatu Hirahara, Aturo Yamamoto, Katuya Kawamori

Publication number: 20040242133Abstract: The a present invention is related to an abrasive cleaning article, made of spread abrasive particles and microencapsulated particles of an aromatizing substance contained in urea-formaldehyde walls, through a three-dimensional non-woven web of fiber that are bonded to the web by a resin adhesive. The item, of any geometric shape, offers the user a sensation of cleanliness due to the constant presence of a “fresh” scent associated to the fiber; the scent remains during the whole life of the abrasive item since the microcapsules break partially during the normal use of the item. The invention also refers to the production process of such abrasive item.Type: ApplicationFiled: July 12, 2004Publication date: December 2, 2004Inventors: Raul Maldonado Arellano, Efren Perez Vazquez

Patent number: 6641465Abstract: There are disclosed a polishing method and a polishing device in which cleaning of a glass substrate surface can be achieved to a high level. A glass substrate (MD substrate 1) in the shape of a circular disc having a circular hole in a center portion is immersed in an abrasive liquid 50 containing free abrasive grains, and an inner peripheral end surface of the glass substrate is polished using the abrasive liquid containing the free abrasive grains by rotating a rotary brush 4 or a polishing pad in contact with the inner peripheral end surface.Type: GrantFiled: July 3, 2001Date of Patent: November 4, 2003Assignee: Hoya CorporationInventor: Takemi Miyamoto
