摘要： A switchgear is provided with interlocks that enhances safety and reliability. On a front face panel, a single line connection diagram, an indicator showing state of ON, OFF and disconnection, another indicator showing a state of an grounding switch, a selection mechanism for selecting manipulation of circuit break, disconnection and grounding, push button switches and for closing and opening a circuit breaker, a manipulation handle insertion hole for disconnecting and a manipulation handle insertion hole for grounding are provided. Depending on positions of a manipulation pin 12 of the selection mechanism, a machine and apparatus to be manipulated is selected. Further, other than the selection of the manipulation the selection mechanism mechanically couples with shutters respectively provided at the manipulation handle insertion hole for disconnecting and the manipulation handle insertion hole for grounding and realizes mechanical interlocks in series of manipulations between circuit break, disconnection and grounding.

摘要： A pull-tab connector for attaching a pull tab's round strap to a slider body is composed of a connector body and a connecting ring on one end of the connector body. The connector body has a transverse through-hole t a side toward the connecting ring, and a pair of longitudinal strap-insertion holes communicating with and perpendicularly to the transverse through-hole and opening to the other end of the connector body and to opposite sides of the connector body via a pair of inwardly tapering longitudinal inlet openings. The strap is inserted through the transverse through-hole and then forced into the longitudinal holes from the respective inlet openings, whereupon opposite ends of the strap are laterally aligned and then pulled to tighten the strap. Thus the strap can be threaded through the connector body simply and neatly, and the threaded strap can be exchanged with another as a demand arises.

摘要： A superconducting magnet includes: first and second torus coolant containers substantially symmetrically, vertically arranged to have a space and a symmetrical plane therebetween for storing a coolant. Each of the first and second torus coolant containers includes therein a main coil bobbin with a main coil for generating a measurement magnetic field, a shield coil bobbin with a shield coil for generating a shielding magnetic field for suppressing outside leak of the measurement magnetic field, a plate member vertically reinforced at a plane thereof opposite to a plane thereof facing the symmetrical plane for supporting the shield coil bobbin and the main coil bobbin. The main coil bobbin is further supported by the shield coil bobbin, to cause the main coil to generate the measurement magnetic field having a substantially uniform magnetic field intensity at a middle region of the space. A magnetic resonance imaging apparatus using the superconducting magnet is also disclosed.
