摘要:
The present invention relates to a zirconium based alloy composite having an excellent creep resistance and, more particularly, to a zirconium based alloy composite finally heat-treated to have the degree of recrystallization in the range of 40˜70% in order to improve the creep resistance. The zirconium based alloy comprises 0.8˜1.8 wt. % niobium (Nb); 0.38˜0.50 wt. % tin (Sn); one or more elements selected from 0.1˜0.2 wt. % iron (Fe), 0.05˜0.15 wt. % copper (Cu), and 0.12 wt. % chromium (Cr); 0.10˜0.15 wt. % oxygen (O); 0.006˜0.010 wt. % carbon (C); 0.006˜0.010 wt. % silicon (Si); 0.0005˜0.0020 wt. % sulfur (S); and the balance zirconium (Zr). The zirconium alloy manufactured with the composition in accordance with the present invention has an excellent creep resistance compared to a conventional Zircaloy-4, and may effectively be used as a nuclear cladding tube, supporting lattice and inner structures of reactor core in the nuclear power plant utilizing light or heavy water reactor.

A triple-axis rotation type headset is described herein that preferably uses a Bluetooth™ module in a main housing that has a first hinge axis longitudinally extended therethrough, and has a rotating housing rotatably attached to the main housing. The rotating housing is rotated about the first hinge axis. To the rotating housing is rotatably attached a connecting member having a second hinge axis longitudinally extended therethrough. The connecting member is rotated about the second hinge axis. The second hinge axis is spaced apart from the first hinge axis. The headset further comprises a hanging member having a third hinge axis provided at one end thereof. The end of the hanging member is rotatably attached to one end of the connecting member about the third hinge axis. The third hinge axis is perpendicular to the second hinge axis. The triple-axis rotation type headset provides improved contact between the headset and an ear of a user of the headset, and convenient key manipulation.

A desktop charger for a portable wireless terminal, comprising: a charger housing; a slot for receiving and holding a stationary body of the terminal, the slot being recessed a determined depth from the front side toward the rear side of the charger housing; and an opening for providing a rotation space for a rotatable body coupled to an end of the stationary body rotatably, the opening extending from a side of the slot in the transverse direction and penetrating the charger housing from its front side to its rear side. The lower body of the terminal can rotate even when the terminal is mounted on the desktop charger. Therefore, the user can perform video communication during charging by using the provided display device and camera lens unit. In addition, wireless communication modules installed at the desktop charger make the connection with an auxiliary device or data communication device easier.

A camera lens assembly for a portable terminal. The camera lens assembly comprises a cylindrical housing having a receiving space extended in the longitudinal direction thereof, a camera holder inserted into or drawn out from the housing at one end of the housing, a bracket fixed to the end of the camera holder and linearly reciprocated in the housing, a guide plate linearly reciprocated on the bracket in the direction perpendicular to the longitudinal direction of the bracket and having a guide groove formed in the shape of a prescribed figure, a supporting cap attached to the other end of the housing and having a guide protrusion formed at the inner circumferential surface thereof and slidably moved along the guide groove for stopping the linear movement of the bracket at least once, and a spring supported by the supporting cap at one end thereof for applying an elastic force to the camera holder in the direction of drawing out the camera holder from the housing.
摘要:
A portable communication device includes a first housing extending in a first direction, a second housing extending in a second direction perpendicular to the first direction and formed at a bottom surface of the first housing so that a predetermined region of an outer circumferential surface of the second housing protrudes perpendicularly outward from the bottom surface of the first housing, and a camera lens module rotatably or linearly movably mounted in the second housing. The camera lens module is inserted into or drawn out from the second housing in the second direction. The camera lens module is repeatedly inserted into and drawn out from the second housing by pushing the camera lens module, and the camera lens module moves upward and downward when it is drawn out from the second housing.
