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 transmitter excellent in high power characteristic in a low frequency band by providing a two-stage displacement enlarging mechanism to said transmitter. CONSTITUTION:An active columnar body 1 is excited for the vertical vibration. Displacement directions of active columnar bodies 2 and 3 are different from that of the body 1. Hinges 12 and 12' and 13 and 13' are so designed that they can have the rigidity enough to effectively transmit the vertical vibration of the columnar body to a lever 14 and will not inhibit the rotation of the lever 14. When the columnar body 1 and those 2 and 3 are displaced by xsi and -xsi1, respectively, the lever 14 rotates inside to develop an enlarged displacement xsi2 at ends P and P'. When the lever 14 rotates inside, each hinge also develops the flexible deformation. However, since the moment is canceled out due to the geometric symmetry, the columnar body 1 will not develop the flexible deformation. 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.

Title: Controlling device for sheet thickness in rolling mill
Inventor: YAMASHITA KOUICHI
IPC: B21B37/18
Filed: 1981-10-16
Abstract: PURPOSE:To enhance the responsiveness to the control of a sheet thickness, and to improve the flatness of a metallic sheet after rolling and the rolling speed, by performing the heating of rolling rolls controlled by an output of a detector for the thickness of metallic sheet placed at the front of the rolls, with the aid of an induction heater instead of an oil heater. CONSTITUTION:Plural induction heating coils 9a-9g controlled by a heating controlling part 10 are provided to the vicinity of rolling rolls 4. When a detecting signal of the thickness of a part (a) of a metallic sheet 1, detected by a detector 2, is transmitted to the controlling part 10, for instance, the part 10 selects a coil 9b locating at the position corresponding to the part (a) in the direction of the sheet 1 width, after judging the excess sheet thickness of the part (a), and outputs a controlling signal to an inverter 11b. Then, high frequency electric current is supplied to the coil 9b to heat and expand a part of the rolls 4 corresponding to the coil 9b, thereby performing the rolling for correcting the excess sheet against the part (a). Thus, the responsiveness to the thickness control is extremely enhanced, because the control is thoroughly performed by electric signals from the detection to the heating of the roll 4 and the rolls 4 are heated by the coil 9 to the temperature higher than the temp. attained by a oil heating.
