A clamp type ultrasonic processor comprises a transducer assembly and a functional gripper. The transducer assembly comprises a transducer () and an amplitude transforming shaft () attached thereto. At least one transducer assembly is connected to the functional gripper. The functional gripper comprises an irradiation front line shaft-approximal block () and an irradiation front line tube-supporting block (), and a functional gripper chamber () is provided in the functional gripper for accommodating an ultrasonic irradiation receiver. The irradiation front line shaft-approximal block () and the irradiation front line tube-supporting block () are connected to grip tightly the ultrasonic irradiation receiver to be irradiated. Irradiation front line shaft-approximal block () and/or the irradiation front line tube-supporting block () are connected to the amplitude transforming shaft (). An application of the clamp type ultrasonic processor and its application in metal production are also provided.

Clamp type ultrasonic processor and application thereof

A method for implementing roam restriction and a system thereof are disclosed in the present invention, by setting up a list of areas where the terminal is allowed to roam. The method includes: the terminal sends a wireless service request to the mobile switching center on the wireless communication network side, wherein the request carries the information of at least one cell currently activated by this terminal; the mobile switching center determines whether there is a cell among the at least one cell currently activated by this terminal, whose cell information is included in the list of areas where the terminal is allowed to roam, if yes, executes current wireless service for this terminal; otherwise, rejects to execute current wireless service for this terminal. With this method, when the number of the cells is increased or changed, there is no need to modify the relationship between the associated IMSI/MIN and the cells or modify the IMSI/MIN of the terminals one by one under the circumstance of migration. Furthermore, since the information of all cells currently activated by the terminal is obtained by the wireless communication network side, when the terminal is located in an overlapped area covered by two cells, this method for implementing roam restriction on the terminal can still be used.
