Abstract: A superconducting arcing induction type DC circuit breaker includes a superconducting fault current limiter and an arcing induction type DC circuit breaker connected in series to each other. The arcing induction type DC circuit breaker includes an induction member that has a through-hole, is continuously formed in a 360-degree direction, and has a certain shape and thickness, and an induction needle that protrudes from an inner surface of the induction member toward a center of the induction member. A contact point where an anode and a cathode, which are mechanical contacts, approach from opposite directions and come into contact with each other is formed in the through-hole of the induction member, and the anode and the cathode are separated in a direction far away from each other.

Abstract: A dual mode terminal including two Subscriber Identity Module (SIM) cards and a method for automatically selecting a SIM card according to network environment in the dual mode terminal is provided. The method includes switching a master/slave setting when a SIM card setting change condition is met in a standby state, and setting a network of a switched SIM card as a master network.

Abstract: An apparatus and a method for setting a main Subscriber Identity Module (SIM) card in a multiple SIM card terminal are provided. The method includes displaying a segmented setting item according to a service type per each SIM card when a main SIM card setting menu is selected, and setting a SIM card selected per the service type as a main SIM card for the corresponding service type when one SIM card per each service type is selected.

Abstract: A Faraday assembly of an ion implantation apparatus includes a Faraday cup in a vacuum chamber, a driving shaft to which the Faraday cup is connected, a motor for inserting the driving shaft further into and drawing the driving shaft out of the vacuum chamber to cause the Faraday cup to advance and retreat within the chamber, and an auxiliary supplier of power for exerting a force that acts on the driving shaft as the driving shaft is being extracted by the motor from the vacuum chamber. Therefore, the force of suction, due to a pressure difference between interior and exterior of the vacuum chamber, is prevented from overloading the motor as the Faraday cup retreats within the vacuum chamber. As a result, the Faraday cup is positioned precisely and efficiently within the vacuum chamber.

Abstract: A mobile station and a method for selecting a public land mobile network thereby which are capable of reducing roaming time and electric current consumption of a mobile station battery by previously determining whether a public land mobile network corresponding to currently received public land mobile network information can be roamed and selectively registering its location in only a base station with a roaming function according to the determination during international roaming.

Abstract: A faraday cup assembly includes a frame attached to a sidewall of a vacuum chamber, a lead screw rotatably attached to the frame, a drive unit which rotates the lead screw, a carrier engaged with the lead screw and horizontally movable with a rotation of the lead screw, a faraday cup located in the vacuum chamber, a shaft extending through the frame and including a first end engaged with the faraday cup and a second end attached to the carrier a brake unit which selectively stops the rotation of the lead screw, and a main controller which controls at least one of the drive unit and the brake unit.

Abstract: Disclosed is an automatic frequency band selection method in a multi-band supported mobile station. In the method, the mobile station checks a Mobile Country Code (MCC) and a Mobile Network Code (MNC) from system information when international roaming has occurred, selects a frequency band corresponding to the MCC and MNC checked from a frequency band information table as a search frequency band, the frequency band information table storing in advance information for frequency bands used according to each country/network, and searches for the selected frequency band, thereby performing network synchronization. According to the automatic frequency band selection method, frequency search time can be reduced, network registration can be performed more quickly when international roaming has occurred, and unnecessary operations can be omitted. Consequently, it is possible to prevent the battery from being wasted.
