Title: Magnetic detector
Inventor: TOMITA TSUKASA
IPC: G01R33/02
Filed: 1995-02-22
Abstract: PURPOSE: To provide a multichannel type magnetic detector in which the influence of a magnetic noise source can be effectively removed even if the position of the source is relatively near to a space to be measured without particularly using a high-order differential gradiometer and without providing a reference SQUID. CONSTITUTION: The detection signals of at least three SQUIDs of SQUID detectors 12(1) to 12(n) for measuring with known position and direction are used, and hence the magnetic vector components of the spaces in which they are disposed can be calculated by calculating means 14b. The vector components corresponding to the positions and the directions of the detectors 12(1) to 12(n) of the SQUIDs can be calculated from the calculated results. The results are subtracted from the signals of the SQUIDs by correction calculating means 14c, thereby removing the magnetic noise components.

Title: Adhesion of thin piece sample
Inventor: SAKAI AKIRA
IPC: G01N1/28
Filed: 1989-02-13
Abstract: PURPOSE:To enable even chemical polishing by a method wherein a hot melting adhesive is placed on a plate glass to set a thin piece sample thereon and then, a hot melting adhesive attached evenly onto the plate glass is melted thermally to be solidified immediately by cooling. CONSTITUTION:A hot melting wax 12 is attached at the center of a plate glass 11. The wax 12 is melted once to be attached evenly onto the plate glass 11. Under such a condition, a thin piece sample 13 is set on the wax 12. Then, the plate glass 11 is heated by a heater 14 again to melt the wax 12 existing between the sample 13 and the plate glass 11. With the liquefaction of the wax 12 and the weight of the sample 13, the wax 12 adheres to the underside of the sample 13 and then, the glass 11 is cooled immediately to solidify the wax 12. As the wax 12 is solidified as staying near the end of the sample 13, it is prevented from penetrating about the surface of the sample 13, thereby enabling the surface thereof to be kept clean.

Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To suppress production of cavitation by providing the sealing water passage of labyrinth structure having a substantially constant flow passage area, and losing energy which high pressure fluid has by flowing friction loss. SOLUTION: Mechanical seal water is flowed from the inlet part 6 of a decompression device 1 to a flow passage 7, collides against a wall face orthogonal to the flow passage 7 while advancing the substantially orthogonal flow passage 7 in the circumferential direction, and flowed while the flow direction is changed. A flowing direction distance is secured long by labyrinth structure, after energy which fluid has is decreased by changing the flowing direction, it is drained from an outlet part 8. In accordance with the flow rate of mechanical seal water, a proper flow speed condition is obtained by securing a proper flow passage area. The number of flow passage bend parts is secured according to required decompression draft, so that proper decompression draft can be obtained.  Thus, in the case where a decompression is used, anxiety of production of erosion and cavitation can be avoided.

Abstract: PURPOSE:To provide a liquid detector which can be easily installed and handled and detect a liquid with high accuracy and, at the same time, a level gauge which can detect the very small movement of a liquid level with high accuracy. CONSTITUTION:Light 25A from an LED 25 is made incident on the face 21 of a prism 20 which is in contact with a liquid 2 at a prescribed incident angle and the totally-reflected light 26A of the light 25A from the part of the prism which is not in contact with liquid 2 due to the difference in refractive index between vapor and liquid is detected by means of a phototransistor 26. Since the quantity of the reflected light 26A varies in accordance with the contact area of the face 21 with the liquid 2, namely, height of the liquid level 2A, the height of the liquid level 2A can be detected from the value of the electric current generated in the transistor 26 in accordance with the quantity of light. Since the detection of the liquid level 2A utilizes the total reflection of the light 25a, even a very small change in the liquid level 2A can be detected with high accuracy.
