    摘要: A small-scale timer assembly includes a PWM signal generator including a selector for selecting one of a plurality of clock sources, a timer for counting based on the selected clock source to deliver an overflow signal, a comparator for comparing the count in the timer against a setting to deliver a coincidence signal, and a signal processor for generating a PWM signal based on the overflow signal and the coincidence signal, and a count controller for counting the number of overflow signals to allow the selector to select another of the clock sources. The PWM signal is used for generating a sinusoidal signal.

    摘要: A thread spreading apparatus for use in an overlock sewing machine capable of performing over-edge chain stitching and other stitching. The thread spreading apparatus uses a lower looper for over-edge chain stitching to allow a needle to surely drop into a triangle defined by a needle thread, a looper thread and the lower looper, thereby enabling multi-thread chain stitching and covering chain stitching to be performed without fail. The apparatus includes a thread spreading hook having hook portions with different heights for retaining needle threads and a projection formed on one of the hook portions. During stitching other than over-edge chain stitching, the hook portions of the thread spreading hook retain the needle threads when two needles drop, thereby allowing each needle to drop into a triangle defined by the looper thread, the lower looper and the corresponding needle thread. During over-edge chain stitching, the hook portions lie rearwardly of an idle chain stitch forming bore provided in a needle plate.
