Abstract: Provided is a torsion bar support structure of a seat belt retractor capable of smoothly rotating a rotary torsion bar and preventing deformation of the torsion bar due to moment applied to the torsion bar by coupling support members to both ends of the torsion bar. The torsion bar support structure of a seat belt retractor includes a housing constituting a main body of the seat belt retractor, a guide drum rotatably coupled to the housing, a torsion bar inserted into the guide drum, a base member fixed to one side of the housing, a locking member fixed to the other side of the housing, and a cylinder accommodating a piston therein to rotate a gear member fixed to the base member, the structure including: a bearing member coupled to the gear member, and a cap surrounding a cover fixing shaft projecting from the locking member, wherein the bearing member and the cap rotatably support the torsion bar when rotation moment is applied in a circumferential direction and an axial direction of the torsion bar.

Abstract: An instrumented capsule for nuclear fuel irradiation tests in research reactors includes an outer shell; a rod tip assembly assembled to a lower end plate of the shell, thus absorbing impact; fuel rod assemblies supported in the shell by means of support tubes and housing therein, sintered fuel bodies and in-capsule instruments, such as thermocouples and self-powered neutron detectors (SPND); a protective tube connected to the upper end plate and protecting instrument control cables; and a guide pipe connected to the inclined extension part of a junction tree and guiding the instrument control cables to a control unit provided outside the reactor.

Abstract: An instrumented capsule for material irradiation tests in research reactors. The instrumented capsule performs an optimum material irradiation test under a testing environment similar to the operational environment of a real reactor. The capsule minimizes the influence of flow-induced vibration caused by forced-circulation-type coolant flow in a research reactor, and overcomes the problems experienced in the conventional breakable parts of instrumented capsules which may be broken during the process of loading/unloading the capsules in vertical irradiation holes of reactor pools. The instrumented capsule includes a capsule main body installed in the vertical irradiation hole. The capsule main body consists of a shell and several instruments, such as thermocouples, dosimeters, a vacuum control pipe, and heaters housed in the shell.

Abstract: A method and system providing an advertisement using a tone of ringing sounds of a mobile phone terminal, and a commercial transaction service in association with the same, is provided. An advertisement is output instead of an incoming call ring sound which rings when a user of the mobile phone terminal receives the call, or for a predetermined time from start of an outgoing call which is achieved by pressing a telephone number of a called party and a SEND button for making a phone call to reception of a response signal of the called party, and a benefit bestowed to the user according to the advertisement listening or watching is spread to product purchase to thereby enhance an advertisement effect.
