Patent number: 6154950Abstract: In a production method of a rotor, a lower layer slot insulator is held at a slot insulator holding portion of a combining jig. A lower layer coil bar is inserted into a coil inserting path of the combining jig and is combined integrally with the lower layer slot insulator by being pushed together. Thereafter, the combined set is set in a coil integrating path of a coil holding member. The coil holding member is attached to a coil inserting device along with an armature core. The lower layer slot insulator and a lower coil trunk are integrally inserted into a slot of the armature core by pushing the lower layer coil bar in the coil integrating path. The lower layer coil trunk and an upper layer coil trunk may be formed integrally with respective coil arms as a single coil bar.Type: GrantFiled: March 6, 1998Date of Patent: December 5, 2000Assignee: Denso CorporationInventors: Koji Katahira, Yasuhiro Ono, Tatsuo Gotoh, Norimasa Okada, Jiro Ebihara, Masayuki Takiguchi

Patent number: 6076267Abstract: A leveling pole which includes a scale visibly provided on a front surface of the leveling pole and at least two colored divisions formed on the front surface of the leveling pole. A border between two adjacent colored divisions of the at least two colored divisions extends in a longitudinal direction of the leveling pole. One of the two adjacent colored divisions and the other of the two adjacent colored divisions are painted a first color and a second color, respectively. A brightness of the first color is different from a brightness of the second color.Type: GrantFiled: February 20, 1997Date of Patent: June 20, 2000Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventor: Tatsuo Gotoh
