  • Publication number: 20030164704
    Abstract: For the purpose of changing the geometry of and spacing between loop coils incorporated into an RF coil without moving the RF coil, loops 200-220 having a geometry optimized for a square sum method employing a phased array, and second small loops 202-222 having a geometry optimized for a sensitivity encoding method are switched by switching elements 24-54 and 25-55 for an open/close operation using a diode 330, and at the same time, first decoupling means 230 and 231 and second decoupling means 240 and 241 are switched. Thus, an operator is not required to replace the RF coil positioned on a cradle, and the loops 200-220 for the square sum method employing a phased array and the second small loops for the sensitivity encoding method can be switched by electronic switching and can be used as RF coils.

  • Patent number: 5698118
    Abstract: A flash welding machine is capable of cutting ends of a pair of preceding and following weld members 1, 2 by means of a shear device 26, 27 and then flash welding them with each other. The flash welding machine can coat an appropriate amount of combustible fluid on the cut end surfaces of the weld members 1, 2. When a first end sensor 31 and a second end sensor 31 sense widthwise leading ends of the weld members 1, 2, a first and a second nozzle 35, 36 start coating the combustible fluid on the cut end surfaces of the weld members 1, 2 from the widthwise leading ends of the weld meets 1, 2. The nozzles 35, 36 stop coating when either one of the sensors 31, 33 senses a widthwise trailing end of one of the weld members 1, 2. Thus, it becomes possible to coat the combustible fluid on the cut ends of the weld members 1, 2 over an area extending from the widthwise leading end to the widthwise trailing end thereof.
