摘要： An anomaly judgment apparatus for a secondary air supply system which includes a secondary air supply path for introducing secondary air into an exhaust path of an internal combustion engine and an open-close valve disposed in the secondary air supply path. The valve is opened and/or closed by drive force of negative pressure introduced from a portion of an intake path of the engine downstream of a throttle valve. The anomaly judgment apparatus includes an anomaly judgment section for judging whether or not the secondary air supply system is anomalous; a negative pressure judgment section for judging whether or not the negative pressure is secured to a degree required for the drive force to reliably open and/or close the open-close valve; and an anomaly judgment prohibition section for prohibiting judgment by the anomaly judgment section when the negative pressure is not secured to the required degree.

摘要： After a winding machine connects a winding wire to a terminal pin, a slackening member is moved in a substantially horizontal direction substantially orthogonal to a direction of a terminal block being extended so as to be located on an orbit of the winding wire. Then, a led part of the winding wire radially between the terminal pin and teeth is extended to the teeth while in contact with a curved surface of a tip of the slackening member. That is, the led part is extended while bent in the substantially horizontal direction. After the winding wire is wound around the respective teeth, the slackening member is moved out of the orbit.
