Patent JP-H03276088-A (JP)
Title: Ultrasonic level gauge
Inventor: MARUYAMA KAZUO
IPC: G01F23/28
Filed: 1990-03-27
Abstract: PURPOSE:To reduce residual vibration by suspending and supporting a cylinder type vibrator below a transmitter receiver main body through a support shaft made of a vibration-preventive member. CONSTITUTION:A vibrator mechanism 6 which includes the cylinder type vibrator 9 is suspended and supported below the transmitter receiver main body 4 through the support shaft 18 which is made of the vibration-preventive member and inserted along a center axis. The area of coupling between the cylinder type vibrator 9 and transmitter receiver main body 4 is therefore decreased and the vibrator 9 is supported at a distance from its vibration surface, so the influence of the supporting upon the respiratory vibration of the vibrator 9 becomes small. Consequently, the resonance between the vibrator 9 and transmitter receiver main body 4 is reducible and a defect in operation due to the influence of residual vibration can be improved.

Filed: 1988-03-31
Abstract: PURPOSE:To facilitate connection with high reliability by horizontally compressing an oil pressure head in the direction vertical to an axial line of a sleeve, and measuring the width between the two faces of sleeve compressed. CONSTITUTION:A wire W is supported by wire supporting means 2, 3c at both sides while it is inserted into a sleeve S, which is arranged between a pair of dies of a hydraulic compressor 4, and the movement is done along the sleeve S while the steps of compression-release-movement are repeated, and thereby compression operation with a specified length is carried out. Since the compression of sleeve S is done simultaneously horizontally from both sides, deformation in compression on both sides is substantially equal without warpage. When the movement of compressor 4 for compression is over, a measuring means 20 rotates a stepping motor 23 normally to make moving plates 25 and a frame 22 move until contacts 29, 27 abut against the two faces of compressed parts of sleeve S. A controller operates, stores and displays the width between the two faces. It is thus possible to confirm the compression results at every compression operation and to refer the aging of compression on another day. The connection with high reliability can be attained in this way.
