Title:
DISTORTION WAVEFORM CONTROL DEVICE, DISTORTION REGULATING MEMBER, DISTORTON WAVEFORM CONTROL METHOD OF DISTORTION WAVEFORM CONTROL DEVICE, AND DISTORTION WAVEFORM CONTROL PROGRAM
Document Type and Number:
WIPO Patent Application WO/2004/029574
Kind Code:
A1
Abstract:
A printed circuit board (2) is horizontally supported on a frame (5) so as to generate distortion in the printed circuit board (2) by a rigid ball dropped from an upper part, and buffer blocks (1A and 1B) are disposed to oppose to front and back sides of the printed circuit board. The buffer blocks (1A and 1B) are movably supported by a movable stage (3) so as to be appropriately brought into contact with the front and back sides of the printed circuit board (2). The buffer blocks (1A and 1B) are appropriately brought into contact with the printed circuit board distorted, regulates the distortion and relatively changes and adjusts peaks of a first distortion waveform and a second distortion waveform generated by impacts, and changes and adjusts the steepness of the distortion.
