Abstract: The present invention addresses the problem of providing a cloth that is excellent in terms of not only flame retardancy but also stretchability, and also a textile product using the cloth. As a means for resolution, a composite yarn is obtained using a spun yarn that contains a flame-retardant fiber having a limiting oxygen index of 25 or more as measured in accordance with JIS K7201 and a conjugate fiber that is made of two components put together in a side-by-side manner or an eccentric sheath-core manner, and then a cloth is obtained using the composite yarn, in which the weight proportion of the flame-retardant fiber is 75 wt % or more based on the weight of the cloth, and the weight proportion of the conjugate fiber is within a range of 5 to 15 wt % based on the weight of the cloth.

Abstract: In an exhaust device for an internal combustion engine, a control device controls a motor based on an output signal of a sensor. The control device has a first valve position detector detecting a first valve position when a valve unit is biased to close using only a biasing force of a spring. The control device has a second valve position detector detecting a second valve position when the valve unit is biased to close using a driving force of the motor that is larger than the biasing force of the spring. The control device detects a foreign object between a valve object and a valve seat and detects a size of the foreign object based on a comparison result between the first valve position and the second valve position.

Abstract: An EGR valve includes an aluminum valve body, an outer metal ring, an inner resin ring, a butterfly valve, and a seal ring. The valve body includes a gas passage therein. The gas passage is part of an EGR passage, through which EGR gas is returned from an exhaust passage to intake passage of an engine. The outer ring has a cylindrical shape, and is fixed and disposed on an inner wall of the gas passage. The inner ring has a cylindrical shape, and is disposed on an inner peripheral wall of the outer ring. The butterfly valve opens or closes an inside of the inner ring, and includes a seal fitting groove at an outer peripheral edge of the butterfly valve. The seal ring is fitted into the groove, and seals a clearance between the butterfly valve and the inner ring when the butterfly valve is closed.

Abstract: In an exhaust system for an internal combustion engine, an output member is configured to transmit power generated by a motor to a valving element via a valve stem. An output shaft is disposed on a rotation central axis of an output gear and coupled with the output gear to be rotatable integrally therewith. A follower is disposed eccentrically relative to a rotation central axis of the output shaft and connected to the output shaft to be rotatable integrally therewith. A first accommodating chamber accommodates at least the valve stem and the follower. A second accommodating chamber accommodates at least the motor and the output gear. A housing includes a housing wall that divides the first chamber from the second chamber. The housing wall includes a first bearing slidably supporting the output shaft in its rotation direction, and a cylindrical first bearing holder holding outer periphery of the first bearing.

Abstract: A full close position limiting member is adapted to be engaged with a valve gear when a valve is driven in a valve closing direction and reaches a full close position of the valve. An intermediate position limiting member is adapted to be engaged with a return spring when the valve is placed on a side of a predetermined intermediate position where a full close position of the valve is located. The intermediate position limiting member receives an intermediate reaction force from the return spring through engagement with the return spring, and the full close position limiting member receives a full close side engaging force from the valve gear. The full close side engaging force and the intermediate reaction force are generally directed in a predetermined direction.

Abstract: A valve apparatus performs at least one of a first operation in which an electric motor is energized in a valve-close direction and a rotation shaft is rotated until its rotation is stopped and a second operation in which the electric motor is deenergized and a valve is fully closed by a biasing force of a return spring. Thereby, a rotation angle of the rotation shaft becomes a rotation-stop angle or the rotation angle becomes in the backlash range, so that a biasing force of the return spring is not transmitted to the rotation shaft. Then, the electric motor generates a specified torque, which is less than a valve-opening torque by which the valve starts opening. Thereby, a rotation angle of the rotation shaft can be stopped at a full-close angle. The full-close angle can be made correspond to an output of a rotational angle sensor.

Abstract: A cam full close stopper defines a cam full close position that is a limit position of a rotatable range of a cam. A sensor element outputs a signal corresponding to a rotation angle of the cam. A signal processor changes the signal output from the sensor element into a sensor output. A storage part memorizes a data table representing a correspondence relationship between the rotation angle of the cam and the sensor output of the signal processor in a predetermined form, characteristics of the sensor output being adjustable at a plurality of points with respect to the rotation angle of the cam. The storage part memorizes the sensor output of the signal processor when the cam is fully closed at the cam full close position.
