Patent number: 8337747Abstract: In a process for manufacturing composite sintered machine components, the composite sintered machine component has an approximately cylindrical inner member and an approximately disk-shaped outer member, the inner member has pillars arranged in a circumferential direction at equal intervals and a center shaft hole surrounded by the pillars, and the outer member has holes corresponding to the pillars of the inner member and a center shaft hole corresponding to the center shaft hole of the inner member. The process comprises compacting the inner member and the outer member individually using an iron-based alloy powder or an iron-based mixed powder so as to obtain compacts of the inner member and the outer member, tightly fitting the pillars of the inner member into the holes of the outer member, and sintering the inner member and the outer member while maintaining the above condition so as to bond them together.Type: GrantFiled: March 11, 2011Date of Patent: December 25, 2012Assignee: Hitachi Powdered Metals Co., Ltd.Inventors: Hiromasa Imazato, Koichiro Yokoyama

Patent number: 8267512Abstract: A recording apparatus has a recording head, a platen, and a first hole. The recording head includes a dot formation element array, and the platen holds a recording medium opposite the recording head. The first hole is disposed in an area of the platen opposite a downstream portion of the dot formation element array and guides ink discarded outside an end of the recording medium when the end is printed without a margin. Alternatively or additionally, a second hole is formed in an area of the platen opposite an upstream portion of the dot formation element array, and the platen guides ink, which is discarded outside an end of the recording medium when the end is printed without a margin, to the second hole.Type: GrantFiled: February 24, 2011Date of Patent: September 18, 2012Assignee: Seiko Epson CorporationInventor: Koichiro Yokoyama
