A brazing method for brazing metal pieces together via a brazing material includes the step of, in a heating chamber controlled to a preset oxygen concentration or less, sandwiching a workpiece of which the metal plates are stacked via the brazing material between a first heating plate and a second heating plate in such a manner that the first heating plate and the second heating plate cover the workpiece entirely as viewed in a thickness direction of the workpiece, and heating the workpiece to braze the metal plates together via the brazing material.

An electrically heated catalyst device includes a catalyst support supporting a catalyst, a surface electrode disposed on an outer surface of the catalyst support and extending in an axis direction of the catalyst support, a wiring line member including a root section extending in the axis direction of the catalyst support and comb teeth-like wiring lines extending from the root section in a circumferential direction of the catalyst support and fixed to the surface electrode, an outer cylinder covering an outer surface of the catalyst support, and a holding member holding the catalyst support and packed between the catalyst support and the outer cylinder, in which the catalyst support is heated by feeding a current through the surface electrode and the wiring line member. At least a plurality of through-holes or a plurality of protrusions are formed in the root section covered by the holding member.

Electrically heated catalyst device and its manufacturing method

A rotation/linear motion converting mechanism includes a shafthaving an external threadon an outer circumferential surface, a nuthaving an internal threadon an inner circumferential surface, and a rollerarranged between the outer circumferential surface of the shaftand the inner circumferential surface of the nut. The roller has a threadthreaded to the external threadand the internal thread. A spur gearand a spur gearare provided in portions of the roller. A spur gearis provided in a portion of the shaft. The spur gearis meshed with the spur gearof the roller. Internal teethare provided in a portion of the nut. The internal teethare meshed with the spur gearof the roller. This improves the lead accuracy of the shaftwhen the nutis rotated.

Rotation/linear motion converting mechanism

An electromagnetic control valve has a passage for conducting fluid. An electromagnetic actuator generates an electromagnetic force. A main valve body opens and closes the passage in accordance with the electromagnetic force generated by the electromagnetic actuator. A bypass is formed in the main valve body. A sub valve body opens and closes the bypass in accordance with the electromagnetic force generated by the electromagnetic actuator. The electromagnetic force generated by the electromagnetic actuator is adjusted such that the sub valve body is opened and closed while the main valve body closes the passage.
