Patent number: 4948091Abstract: A motor-operated valve is constructed such that a stator is provided outside of a nonmagnetic tubular member allowing flow of a fluid, with stator coils wound around a plurality of magnetic poles, and a plurality of permanent magnets are secured to an operating surface of each magnetic pole. The permanent magnets are magnetized into a number of pole-pairs arranged at a constant pitch. A rotor is rotatably supported inside of the tubular member. A number of induction teeth are formed along the circumference of the rotor at a pitch equal to the pitch of the pole-pairs of the permanent magnets, and the total number of the induction teeth is so selected that it is different from the total number of the pole-pairs of the permenant magnets by an amount equal to an even number. A mechanism including a rotation-preventing means is also provided in the rotor for converting the rotating movement of the rotor into a linear movement of a valve member.Type: GrantFiled: February 16, 1990Date of Patent: August 14, 1990Assignees: Kabushiki Kaisha Yaskawa Denki Seisakusho, Toyo Engineering CorporationInventors: Ikumi Satoh, Jun Nakano, Riichiroh Harada, Tatsuhiko Koba, Yuichi Fujita, Kazumi Shima

Patent number: 4347221Abstract: A catalytic converter is disclosed, which incorporates an improved mechanism to supply a part of a make-up gas for temperature control. A plurality of stages of a gas injection device are provided in the main body of the catalytic converter, each of the stages of the gas injection rings consisting of a plurality of gas injection rings concentrically arranged therein. Each of the gas injection rings is interconnected through connecting tubes to each of the small chambers which corresponds to each of the stages of the gas injection rings and is provided in a make-up gas supply chamber.Type: GrantFiled: March 2, 1981Date of Patent: August 31, 1982Assignee: Toyo Engineering CorporationInventors: Jun Zamma, Isao Makino, Toshiyuki Mii, Kazumi Shima
