Patent number: 7930826Abstract: When an outer circumference of a clamping portion 25 and an outer circumference of a circular outer circumference 26 are restrained by a die 6 while inserting a non-circular punch 5 into a circular hole 28, paddings 27, 27 are pressed by a semi-circular inner circumference of the die 6 to thereby be forced into interior of the circular hole 28. The volume of the paddings 27, 27 is set to be substantially the same as a volume obtained by subtracting the volume of a non-circular hole 23 in an extension shaft 2 from the volume of the circular hole 28. The circular hole 28 is deformed, and the paddings 27, 27 forced into the circular hole 28 abut with inclined planes 52, 52 of the punch 5, whereby the non-circular hole 23 is formed in the extension shaft 2.Type: GrantFiled: October 31, 2007Date of Patent: April 26, 2011Assignees: NSK Ltd., Gunma Seiko Co., Ltd.Inventors: Koji Inoue, Yasushi Watanabe, Koji Marumo, Junichi Okada

Patent number: 7735359Abstract: A process quantity measurement method with which an engine output is accurately measured in a relatively simple manner. Torque of an engine is measured based on the amount of torsion of the output shaft of the engine, and an engine output is obtained based on the measured torque. On the other hand, an engine output is calculated based on input and output heat quantity, and a difference between the engine output based on the torque and the engine output based on the input and output heat quantity is obtained in advance. When the engine is operated, the previously obtained difference is added to the engine output that is based on the calculated input and output heat quantity to obtain the engine output.Type: GrantFiled: November 14, 2005Date of Patent: June 15, 2010Assignee: The Tokyo Electric Power Company, IncorporatedInventors: Shuichi Umezawa, Junichi Okada
