Title: Sediment press feed device
Inventor: FUJIWARA NORIO
IPC: F17D1/14
Filed: 1987-07-30
Abstract: PURPOSE:To reduce the frictional resistance between sediment and a sediment press feed pipe so as to greatly enhance the press feed efficiency by supporting the sediment press feed pipe by means of a vibration suppressing mechanism, and by providing an ultrasonic wave transmitting device on the outer periphery of the sediment press feed pipe. CONSTITUTION:Ultrasonic wave having a predetermined frequency is generated when an ultrasonic wave transmitting device 14 is energized, and is transmitted through a pedestal plate 16 to a sediment press feed pipe 10 which is accordingly vibrated with the same frequency, resulting in that the contact area between sediment and the inner surface of the press feed pipe 10 is extremely decreased. Even though the inner surface of the press feed pipe 10 has a surface roughness of micron order, the frictional resistance between the sediment and the inner surface of the press feed pipe 10 may be reduced. Since the sediment press feed device 10 is supported by a vibration suppressing mechanism, it is possible to prevent ultrasonic wave from affecting the surroundings.

Filed: 1995-07-25
Abstract: PROBLEM TO BE SOLVED: To enhance reliability of measurement and the work efficiency by measuring the distance between incident points of an oblique probe, operating a refraction angle based on the measured distance and the thickness of a specimen, and indicating the operation results. SOLUTION: A frame 2 houses transmission and reception oblique probes T, R such that the interval can be varied only in the facing direction. A drive means 3 imparts a driving force to any one of the probes T, R. An optical distance measuring means 5 measures the distance Y between incident points of oblique probes T, R and means 4 detects and indicates a transmitted echo. Means 6 operates a refraction angle θ based on an output from the means 5 and a previously inputted thickness (t) of a specimen 1 and then indicates the operated refraction angle θ. Since the operations for reading the distance Y and calculating the refraction angle θare automated, reliability of measurement and work efficiency are enhanced.

IPC: A61B17/22
Filed: 1988-07-27
Abstract: PURPOSE: To precisely observe and position a calculus with a compact structure by providing central opening parts on a coil support body, a flat coil, and a metal diaphragm, respectively, so that the ultrasonic head of an ultrasonic transmitter-receiver can be inserted thereto. CONSTITUTION: The impulse source 3 of an impulse generator 1 and a lens device 6 have central opening parts 9, 10, respectively, both the opening parts 9, 10 are mutually connected by a tube body 11. The impulse source 3 of the impulse generator 1 generates a flat wave-like impulse, and this impulse is focused to a focus F by the acoustic lens device 6. Since an ultrasonic head 12, for example, a sector scanner is arranged in the central part of the impulse generator 1, its central axial line is similarly directed to the focus F. Therefore, regardless of the rotating direction of the ultrasonic head 13, or the direction of the sector ultrasonic wave, the focus F can be regularly detected by the ultrasonic wave. Thus, a calculus can be detected ultrasonically, and it can be visually confirmed through a monitor.
