VARIABLE IMPEDANCE DEVICE WITH FINE ADJUSTMENT MECHANISM |
摘要 |
<p>An assembly for fine adjustment of a variable impedance mechanism is disclosed wherein a first disk-shaped rotary member, which functions as a knob, has a spiral ridge or groove formed on one side surface thereof for engagement with the teeth of a second disk-shaped rotary member or teethed wheel whose shaft is in turn coupled to the rotary shaft of a variable impedance element. When the first rotary member makes one rotation, the second rotary member is advanced one tooth, whereupon the fine adjustment of the variable impedance element is possible.</p> |
