    Abstract: According to the present invention, there is provided an automatic rotating-type turret device for work machinery, in which a lift-type turret is not used. The configuration makes it possible for a clutch device to lock a turret using one drive device (actuator), and generates a wedge effect, thereby obviating the need for a large driving force capable of directly countering a load during cutting operation. The turret can even be locked using air or a small driving force generated by a motor and obviates the need for hydraulics. The automatic rotating-type turret device for work machinery is provided with an axial-direction slide body 7, which is advanced or retracted in the direction of the axis of rotation of the turret 3 by the drive device 5 advancing or retracting the drive body 6 in a direction orthogonal to the direction of rotation axis; and a clutch device 4 that is engaged or disengaged by the axial-direction slide body 7 being advanced or retracted, the turret 3 being of a non-lift-type, and there being provided to the drive body 6 a tapering action part 8 for generating an expanding action caused by the movement of the drive body 6 and pressingly sliding the axial-direction slide body 7 against the turret stage 1.

    Abstract: A light-emitting device includes an active region, an n-type region, a p-type region, an n-electrode and a p-electrode. The active region is formed from a semiconductor material. The semiconductor material has a tetrahedral structure and includes an impurity. The impurity creates at least two energy levels connected with the allowed transition within a band gap of the semiconductor material. The n-type and p-type regions in contact with the active region are disposed between the n-type and p-type regions. An excitation element is configured to inject an electron from the n-type region and inject a hole from the p-type region so as to generate an electron-hole pair in the active region. The active region has a thickness no less than an atomic distance of the semiconductor and no more than 5 nm.
