Filed: 1985-03-29
Abstract: PURPOSE:To reduce the cleaning time, by introducing an cleaning liquid through a cleaning liquid introduction port provided on the head of an egg-shaped chamber to push down a mobile port with a liquid pressure thereof. CONSTITUTION:A mobile port 14 and a cleaning liquid introduction port 15 are provided on the head of an egg-shaped chamber 1. As a cleaning liquid is introduced from the introduction port 15, the mobile port 14 is pressed down under the pressure thereof together with a sample liquid introduction tube 13 against the charging force of a coil spring 16 and a valve is opened. The cleaning liquid is jetted forcefully from the perimeter of the mobile port 14, flowing down the inner wall of the chamber 1. The inner wall of the chamber 1 has such a large angle of inclination as to make the cleaning liquid jetted out of the mobile port 14 flow down with an increased flow velocity, thereby permitting thorough cleaning of the inner wall of the chamber 1. After the end of a cleaning, the cleaning liquid is drained outside through a sample liquid drain port 6, a tubular body 11 and a three-way valve 10. Thus, the cleaning of the chamber 1 can be done in a short time with a limited amount of the cleaning liquid.

Title: Measurement of surface flaw in non-destructive manner by magnetization by plurality of frequencies
Inventor: UETAKE ICHIZO
IPC: G01N27/83
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To rapidly and accurately measure the surface flaw of a material while dispensing with confirmation work of the amplificution factor of a measuring apparatus by magnetizing the material by using the alternating magnetic fields by a plurality of frequencies. SOLUTION: A material is magnetized by using the alternating magnetic fields by a plurality of frequencies and the leak magnetic flux 12 generated by the flaw 11 present on the surface 10 of the material is detected and signal output is separated into a plurality of frequency components to calculate the output ratio of signals to evaluate the flaw 11. That is, the flaw 11 present on the surface 10 of the metal material magnetized by the alternating magnetic fields by a plurality of frequencies is confirmed as the detection by the magnetic sensor 13 of the leak magnetic flux 12. The detection signal thereof is separated into signal components synchronous to a plurality of magnetizing frequencies to evaluate the flaw 11 from the output ratio of the respective signals.  Since a constant output signal ratio is always obtained in the case of the same flaw even if the amplificution factor of a measuring apparatus fluctuates in order to take the output ratio by the signal components of a plurality of frequencies, it is unnecessary to confirm the fluctuations of the amplificution factor on the way of measurement.

IPC: B21B45/06
Filed: 1986-03-25
Abstract: PURPOSE:To improve the descaling efficiency by blasting powdered abrasives whose diameters are smaller than a prescribed size onto the surface of steel plates using high pressure water to meet a specific energy conditional equation and then performing ultrasonic pickling. CONSTITUTION:Powdered abrasives such as iron powders whose diameter are smaller than 0.2mm are blasted onto the surface of a hot rolled steel plate to be treated to perform a pretreatment. Then the hot rolled steel plate 1 is carried into a pickling bath 3 provided with ultrasonic oscillators 2 and is put on a support table 4 to be subjected to the ultrasonic pickling. An actual projection energy E of the abrasives at the pretreatment and an ultrasonic energy I are adjusted to meet a conditional equation. In that method, a synergistic effect of the abrasives' energy E and the ultrasonic energy I is made to be remarkable, so that a simple and quick descaling even for high alloy steels is performable. Therefore, the descaling efficiency is improved.
