摘要： A chuck mechanism for a dental handpiece and a dental handpiece with the chuck mechanism are disclosed. The chuck mechanism holds the columnar rotary tool for dental care rotatably with an annular rotor of the dental handpiece and the columnar rotor tool is concentrically detachable to the annular rotor which is rotatably attached to a head part of the dental handpiece. The chuck mechanism is characterized by an annular chucking member which comprises a cylindrical base part into which the annular rotor is integrally fitted and an elastic chucking piece having a chucking pawl for engaging with a locking groove formed at a base end of the rotary tool. The chuck mechanism enables the rotary tool to be easily removed from the annular rotor by elastically deforming the elastic chucking piece against elastic force of the elastic chucking piece to disengage the chucking pawl from the locking groove.

摘要： A varistor having a favorable heat-dissipating property is provided.In the varistor, a composite part having a favorable heat-dissipating property formed by a composite material composed of ZnO and Ag is arranged between main faces of a varistor matrix. Therefore, the heat transmitted from a semiconductor light-emitting device to a varistor part through an outer electrode can rapidly be transferred toward a main face on the opposite side through the composite part. In this varistor, side faces excluding inner side faces are exposed at side faces of the varistor matrix. Such a structure yields a favorable heat-dissipating property.
