摘要:
A rotor of a motor includes an engaging portion that engages an annular portion of a yoke based on movement of a rotatable shaft in a thrust direction to brake the rotatable shaft. There is provided a Belleville spring that limits the movement of the rotatable shaft in the thrust direction to prevent engagement of the engaging portion with the annular portion when a thrust load applied on the rotatable shaft is equal to or smaller than a predetermined value. Furthermore, the Belleville spring allows the movement of the rotatable shaft in the thrust direction to allow the engagement of the engaging portion with the annular portion when the thrust load applied on the rotatable shaft is larger than the predetermined value.

A thermosetting composition comprises (A) a compound having in the molecule two or more carboxyl groups blocked by a vinyl ether compound, a vinyl thioether compound or a hetero compound having a vinyl type double bond and oxygen or sulfur as the hetero atom, (B) a compound having in the molecule two or more reactive functional groups which can form chemical bonds with the blocked carboxyl groups, and (C) a dispersing component of at least one inorganic oxide sol selected from the group consisting of aluminium oxide sol, silica sol, zirconium oxide sol and antimony oxide sol, and optionally (D) a thermal latent acid catalyst which is activated during curing the composition by heating. A method of coating and a coated article comprise applying the composition. The obtained paint film has excellent weathering resistance, stain resistance, stain-removing property, chemical resistance, moisture resistance and excellent appearance.

A semiconductor module having a compact antenna element capable of providing desired directivity therein has been disclosed. When an electromagnetic-wave radiation window has the capability of a lens, directivity can be set arbitrarily. For improving directivity, a convergent lens for converging millimeter waves or quasi millimeter waves is employed. For impairing directivity, a divergent lens is employed. In the case of the convergent lens, a direction in which radio waves are radiated or received by the antenna element can be set by deviating the center axis of the lens from the center of the antenna element.

A coil component comprises a wire, a terminal pin around which an end of the wire is wound, a terminal section for fixing one end of the terminal pin and for allowing the terminal pin to project therefrom. A conductive connection member is connected to the terminal pin so that it can be electrically connected to the wire. The terminal pin has a diameter on an open side thereof which is formed larger than that on a root side form which the conductive connection member is drawn out. The pin is formed as a contact section with which the conductive connection member makes contact when it is pulled in a projection direction of the terminal pin.

A motor comprises a motor rotation shaft, a first thrust bearing which supports one end of the motor rotation shaft and a second thrust bearing which supports the other end of the motor rotation shaft to control positioning in a thrust direction of the motor rotation shaft. The first thrust bearing further comprises a bearing for supporting one end of the motor rotation shaft and is movable in a shaft direction of the motor rotation shaft, a guide member for guiding the movement of the bearing in the shaft direction and a plurality of pre-loaded elements for opposing the force generated by the bearing in the shaft direction. The pre-loaded elements are evenly spaced around the motor shaft.
