Patent number: 7829306Abstract: A gene encoding a production amount-potentiating factor is introduced into an animal cell to transform the cell. Alternatively, a protein production gene and the gene encoding the production amount-potentiating factor are introduced into the animal cell to transform the cell. Herein, as the production amount potentiating factor, there is used a factor having caspase activity inhibiting activity and/or protein biosynthesis activity potentiating action, for example, baculovirus P35. Further, the animal cell is cultured by a culturing method under a condition that apoptosis is not induced, so that a protein is mass-produced.Type: GrantFiled: October 21, 2004Date of Patent: November 9, 2010Assignee: Juridical Foundation the Chemo-Sero-Therapeutic Research InstituteInventors: Reiko Matsuyama, Hiroaki Maeda, Hitomi Shirahama, Takayuki Imamura, Yasuharu Kamachi

Patent number: 7685670Abstract: An input disk, a clutch disk and wave washers are installed to an output shaft to form an output shaft assembly of a motor apparatus. The input disk is axially non-detachable from the output shaft and is rotatable about an axis of the output shaft. The input disk is driven by a drive force supplied from a motor main body of the motor apparatus. The clutch disk is supported by the output shaft in such a manner that the clutch disk is non-rotatable relative to the output shaft and is axially movable along the output shaft relative to the input disk. The wave washers apply a resistive force against axial movement of the clutch disk from a coupled state, at which the input disk is coupled with the clutch disk to rotate together.Type: GrantFiled: November 2, 2004Date of Patent: March 30, 2010Assignee: ASMO Co., Ltd.Inventors: Hideyuki Yagi, Takayuki Imamura

Patent number: 7568257Abstract: Initiation of coupling between an input disk and a clutch disk at a maximum rotational coupling force without making relative rotation between the input disk and the clutch disk is enabled only when the output shaft is placed in a single engageable point within a normal reciprocal angular range of the output shaft. When a load applied to the output shaft is equal to or greater than a predetermined value, the input disk and the clutch disk are decoupled from one another, so that the relative rotation is made between the input disk and the clutch disk.Type: GrantFiled: November 2, 2004Date of Patent: August 4, 2009Assignee: ASMO Co., Ltd.Inventors: Hideyuki Yagi, Takayuki Imamura
