Title: Low frequency underwater ultrasonic transmitter
Inventor: INOUE TAKESHI
IPC: H04R1/44
Filed: 1984-08-07
Abstract: PURPOSE:To offer a small-sized two-way or nondirectional echo sounder transmitter excellent in high power characteristic in a low frequency band by providing two-stage displacement enlarging mechanism to said transmitter. CONSTITUTION:An active columnar body 31 is excited for the vertical vibration. A non-active columnar body 41 made of high tensile steel is so designed that it can have a large rigidity with respect to the vertical displacement and can be flexible with respect to a flexible displacement. When the columnar body 31 is displaced by xsi1, a lever 34 rotates inside to develop an enlarged displacement xsi2 at ends P and P'. At this time, the columnar body 41 having a thick base part 31' transmits efficiently the vertical displacement of the columnar body 31 to the lever 34. Even when the lever 34 rotates with respect to the 1st stage displacement enlarging mechanism, structually the flexible moment is canceled out, and the flexible moment arising in the columnar body 31 goes to approximately zero. In terms of the 2nd stage displacement enlarging mechanism, when the displacement by xsi2 occurs at the points P and P', the displacement several times larger than the xsi2 is given as shown by the double arrows owing to the form effect of a convex shell.

Abstract: PURPOSE:To reduce the processing volume of a discrete cosine transformation by judging whether it is a valid block or an invalid block before executing a discrete cosine transforming process, and omitting the discrete cosine transforming process when judged to be the invalid block. CONSTITUTION:A predictive error signal is inputted into a judging part 19, and a judgement whether the valid block or the invalid block is executed before the discrete cosine transforming process in a discrete cosine transformer 12.
