摘要： An automatic lower-thread winder for use with a sewing machine which automatically rewinds lower thread around a bobbin loaded into the bobbin case, strings the bobbin case with the lower thread, and cuts the lower thread after the bobbin case is strung. The lower-thread winder removes slacks of the lower thread created during the stringing operation. The lower-thread winder is programmed to retry a predetermined number of automatic retrials of the stringing operation, and checks if it has succeeded in the stringing operation. As a consequence, even if it fails in the stringing operation, it repeats the stringing operation automatically or warns the operator. Thus, the lower-thread winder effectively prevents malfunctions caused by defective stringing operations.

摘要： An under thread supply apparatus for a sewing machine comprises a bobbin case, a bobbin exchange device, a thread removal device and a winding device. The bobbin case is removably set to a shuttle of the sewing machine and accommodates a bobbin with the thread wound thereon. The bobbin exchange device takes the bobbin case out of the shuttle, and set the bobbin case accommodating the bobbin with the thread wound anew therearound to the shuttle. The thread removal device removes the thread from the bobbin accommodated in the bobbin case which is taken out. The winding device winds a preset amount of thread around the bobbin after the thread is removed therefrom.

摘要： Three basic types of iron-base alloys are disclosed as follows. An iron-base alloy having excellent workability comprising 2 to 60 atomic % of at least one of Ni and Mn, 7.5 to 60 atomic % of Cr, 0.5 to 12 atomic % of Al, 0.5 to 10 atomic % of at least one of C, B and P and the balance consisting substantially of Fe. An iron-base alloy having excellent workability comprising 2 to 60 atomic % of at least one of Ni and Mn, 7.5 to 60 atomic % of Cr, 1 to 15 atomic % of Si, 0.5 to 10 atomic % of at least one of C, B and P and the balance consisting substantially of Fe. Also provided is an iron-base alloy having excellent workability comprising 2 to 60 atomic % of at least one of Ni and Mn, 7.5 to 60 atomic % of Cr, 0.25 to 15 atomic % of Si, 0.5 to 10 atomic % of at least one of C, B and P, 0.02 to 0.5 atomic % of Al, and the balance consisting substantially of Fe. These Fe-base alloys are highly ductile and have high workability. By cold-working, they have very high tensile strength, and superior corrosion resistance and fatigue resistance to conventional Fe-base alloy materials. They are very useful as various industrial materials and composite materials.
