Patent number: 8322759Abstract: In a pod used in an FIMS system, an engaged portion is provided on the outer surface of the lid of a pod. A through hole is provided in a flange portion that is provided around the pod opening and in which the lid is to be received. The through-hole allows access to the engaged portion from the external space. A latch mechanism is supported on the pod body side surface of the flange portion in such a way that it can slide in a direction parallel to the side wall of the flange. The engagement portion of the latch mechanism reaches the engaged portion through the aforementioned through-hole. Movement of the latch mechanism brings the engagement portion into an engaging state and a disengaged state.Type: GrantFiled: November 10, 2009Date of Patent: December 4, 2012Assignee: TDK CorporationInventors: Tsutomu Okabe, Toshihiko Miyajima, Hiroshi Igarashi

Patent number: 8300243Abstract: When an image to be printed is specified in a print system for printing images, a telephone number or e-mail address is entered as a contact destination to be contacted when printing ends. At the conclusion of printing, the entered contact destination is so notified. Upon being so notified of end of printing, the user returns to the location at which the print system has been installed. Since the user will thus know when printing ends, the user can make effective utilization of time until printing ends.Type: GrantFiled: August 7, 2001Date of Patent: October 30, 2012Assignee: Fujifilm CorporationInventors: Sugio Makishima, Hiroshi Igarashi

Patent number: 8285182Abstract: A fixing device has a frame, a heating roller, a press roller, a peeler, a guide member, and a wheel. The heating roller includes a roller rotation axis and a cylindrical surface. The press roller is pressed against the cylindrical surface to feed a recording medium together with the heating roller along a feeding path. The peeler has a peeling surface having a leading edge, where the peeling surface faces the feeding path. The guide member faces the peeling surface to guide the recording medium to downstream of the feeding path. The guide member is movable between a near position and a far position relative to the peeling surface. The wheel is positioned in a manner that a part of the circumferential edge protrudes from the peeling surface to the guiding member in a virtual plane perpendicular to the wheel rotation axis.Type: GrantFiled: November 29, 2007Date of Patent: October 9, 2012Assignee: Brother Kogyo Kabushiki KaishaInventors: Tomitake Aratachi, Hiroshi Igarashi

Patent number: 8186927Abstract: A transfer chamber is partitioned into a second chamber in which a transfer robot moving through an opening portion which can be opened/closed by a door is arranged, and a minute first chamber which serves as a FIMS system and includes a door capable of retaining a lid of a pod. The second chamber maintains a state in which an inert gas constantly circulates owing to minute nitrogen while having a pressure higher than that inside the first chamber. The first chamber is normally sealed while an oxide gas is suppressed in advance. In addition, at a time of transferring wafers, a partial pressure of the oxide gas is lowered with use of a downflow which is caused by the inert gas. Further, the first chamber and the second chamber are communicated with each other after a level of the partial pressure is confirmed with use of an oxygen level meter.Type: GrantFiled: May 26, 2009Date of Patent: May 29, 2012Assignee: TDK CorporationInventors: Tsutomu Okabe, Toshihiko Miyajima, Hiroshi Igarashi

Publication number: 20120076536Abstract: A developing cartridge that maintains a pressing condition to press a developer carrier against the image carrier is described. The developing cartridge may include a coil spring that presses the developer carrier against the image carrier. The coil spring may include a handle that transmits a pressing force to the coil spring via the contacting member. By doing so, every time the developing cartridge is replaced, a new coil spring and handle can be provided for the color laser printer with the developing cartridge attached. Therefore, a constant pressure by the coil spring can be continuously maintained. Thus, a preferable pressure condition of the developer carrier against the image carrier can be continuously maintained.Type: ApplicationFiled: November 23, 2011Publication date: March 29, 2012Applicant: Brother Kogyo Kabushiki KaishaInventors: Hiroshi IGARASHI, Naoya KAMIMURA

Patent number: 8062406Abstract: A process for producing metallic ultra-fine powder, which can use a raw material which is spread over a wide range, and control freely the grain size of the metallic powder to be produced, at low cost and high safety. The process for producing the metallic ultra fine powder consists of using a burner and a furnace which can generate a high temperature reductive atmosphere, and an apparatus for separating gas which is generated in the furnace from powder to recover the powder. The burner has a function of blowing a powdery metallic compound as a raw material into a high temperature reductive flame. The raw material powder is efficiently heated in airflow of a high temperature reductive flame, thereby being reduced rapidly into metallic ultra-fine powder. At this time, the grain size of the metallic ultra-fine powder is controlled by adjusting the oxygen ratio (i.e.Type: GrantFiled: December 22, 2005Date of Patent: November 22, 2011Assignee: Taiyo Nippon Sanso CorporationInventors: Hiroshi Igarashi, Takayuki Matsumura, Shinichi Miyake
