Filed: 1993-06-01
Abstract: PURPOSE:To make it possible to perform a quick speed control to a target speed by controlling electric power control means in such a manner that the detecting speed of a traveling motor becomes a command speed. CONSTITUTION:First judged speed setting means M7 set a first judged speed A1 which is higher by a predetermined quantity than a command speed A from command means M5, and second judged speed setting means M8 set a second judged speed A2 which is higher by a predetermined quantity than the first judged speed A1.

Abstract: PURPOSE:To obtain a signal having a desired frequency characteristic with simple constitution by constituting at least one of a couple of electrodes into an inter-digital electrode having a shape spread gradually and arranging a grating structure reflecting a surface acoustic wave of a prescribed frequency to a prescribed location between the electrodes. CONSTITUTION:Electrode fingers 26a, 26b are arranged interdigitally, the tip of the electrode finger 26a approaches gradually toward a common electrode 24b and the tip of the electrode finger 26b is spread gradually toward the common electrode 24a.
