摘要： An apparatus for flicker protection when a servo motor driven sewing machine starts utilizing comparators. Setting the original voltage as the reference voltage and the dropped voltage as the monitor voltage, the comparator compares the voltages and, if the difference exceeded more than the predetermined value, signals for setting the maximum electric current to the servo motor are attenuated such that the voltage drop of the electric source will be reduced.

摘要： A sewing machine needle mounting device includes a grip portion and a needle engaging portion. A vertical hole is vertically passed through the engaging portion. The hole may be configured in two shapes. One preferred configuration is an inversed cone which includes a substantially vertically extending ledge to fit within a thread guide of a sewing machine needle. Another preferred configuration is an inversed hemicone to engage with a flat surface of the sewing machine needle. The invention is useful for mounting needles to needle bars of both domestic and industrial sewing machines.

摘要： A method and an apparatus for picking up a fabric workpiece by applying vacuum provides two vacuum sensors; one for a sample fabric and the other for a fabric workpiece to be picked up. Where the apparatus has picked up incorrect number of sheets, the two vacuum sensors will output different voltages and the values are converted from analog to digital and input to a comparator. Thus, in such a case, the comparator outputs particular signals to stop the picking-up action of the apparatus.
