Patent number: 8777363Abstract: A transport method for transporting a long medium in a recording apparatus is performed using a transport control section. The transport control section performs, in a case where a first motor and a second motor are driven so as to transport a long sheet to the downstream side in a transport direction, prescribed processing that is different from the processing in a case where the deflection amount of the sheet becomes equal to or greater than a reference amount, in a case where the deflection amount of the sheet between a shaft member and a sending roller in the transport direction does not become equal to or greater than the reference amount.Type: GrantFiled: October 4, 2013Date of Patent: July 15, 2014Assignee: Seiko Epson CorporationInventors: Masato Mitsuhashi, Yasuharu Harada

Patent number: 8356894Abstract: An ink jet recording apparatus includes a recording head which discharges ultraviolet curing inks toward a recording sheet while reciprocally moving in a reciprocal movement direction M crossing a transportation direction S of the recording sheet; and an ultraviolet irradiation head which irradiates ultraviolet rays toward the ultraviolet curing inks discharged from the recording head and attached to the recorded medium. The recording head includes a going recording head and a returning recording head which are disposed at the front and the back of the reciprocal movement direction M with respect to a region in which the ultraviolet irradiation head irradiates the ultraviolet rays to the recording sheet.Type: GrantFiled: October 10, 2008Date of Patent: January 22, 2013Assignee: Seiko Epson CorporationInventors: Tsunenobu Endo, Kazuma Ozaki, Tsuyoshi Otani, Atsushi Sumii, Yasuharu Harada

Patent number: 6568845Abstract: A stationary mixing machine for mixing various fluid materials in a line. In a fluid path, a pair of mixing element portions 2 and 3 is concentrically arranged. At a surface formed by overlapping these mixing element portions 2 and 3, a respective fluid path is formed as mixing chambers 8 (13) at the both elements. These mixing chambers are peripherally, radially and concentrically, arranged. Fluid material flown from an opening 5 provided at a central portion of one of the mixing element portions 2 and 3 is flown in a radius direction, the juxtaposed mixing chambers in the adjacent rows can be communicated each other and a shearing stress is applied by providing a partition or a step so as to accomplish uniformly mixed and finely-dividing dispersing action.Type: GrantFiled: April 26, 2001Date of Patent: May 27, 2003Assignee: Matrix Global Technology Ltd.Inventor: Yasuharu Harada
