Title: Method for analyzing non-metal inclusion in metal
Inventor: YAMAMURA HIDEAKI
IPC: G01N33/20
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To highly accurately and quickly analyze a total amount of an inclusion and the amount of a constitutive primary component, by irradiating a metal piece with X rays generated while a voltage of an X-ray generation tube is set in a specific range. SOLUTION: A metal piece is irradiated with electron beams by an electron beam generation device set in a vacuum container, thereby dissolving the metal piece. An internal inclusion contained in the metal piece is consequently moved to a surface of the dissolved metal. Then, the surface of the cooled and solidified sample is indicated with X rays generated while a voltage of an X-ray generation tube is set to be approximately 5-25 kV. The sample is analyzed by X-ray fluorescence analysis, whereby the amount of constitutive elements of the non-metal inclusion is measured and the non-metal inclusion is analyzed. Since the inclusion is collected at the surface by the dissolution, the amount of the inclusion can be determined correctly when an intensity of characteristic X rays generated by primary X rays is detected by a detector.  The determination can be made automatically because of the elimination of the need for separating the inclusion part from the metal part with human eyes.

Title: Waterproof structure of connector
Inventor: KOBAYASHI KOJI
IPC: H01R13/52
Filed: 1998-05-11
Abstract: PROBLEM TO BE SOLVED: To prevent water infiltration surely at a connecting part between a cover and a rubber boot. SOLUTION: A ring fit protrusion 55 formed on an adhesion face 29 of a female-side cover 20F is fitted with a ring fit depression 56 formed on an adhesion plane 34 of a rubber boot 30. These ring fit protrusion 55 and ring fit depression 56 surround a whole circumference of a wire outlet hole 51 of the female-side cover 20F. Therefore, even if an interstice occurs between the adhesion faces 29 and 34 and water infiltrates into a connector from the outside, this waterproof structure prevents the water from infiltrating further into the wire lead out hole 51 side across a fitting part of the ring fit protrusion 55 and the ring fit depression 56.

CONSTITUTION:A current of 50-200mA flows between a wiring electrode 12 and an ohmic electrode 16 to write a memory cell, and the electrode 12 is buried in a semiconductor substrate 10 by heat generated at that time. After writing, a depletion layer 15 of a region in which the electrode is buried is introduced to the end of an impurity region 13, a current passage between a reading electrode 11 and an ohmic eleotrode 16 is interrupted, thereby becoming a high resistance writing state. The memory cell is read by applying a current of approx. 1 mA from a reading bit line 22a with a word line 23a or 23b as a ground potential. At this time, a potential corresponding to writing or reading state is generated at the reading bit line 22a. Thus, the wiring width of the bit line is reduced to increase the operating speed.

Namely, rotor holes 1 and 1A and pilot holes 2 and 2a are blanked in the 1st process and stator holes 3 and 3A are blanked in the 2nd process. Blanked plates for rotor 4 and 4a are blanked in the 3rd process, and the blanked plate are taken out through a chute installed to the lower part of the die. Blanked plates for stator 5 and 5A are blanked in the 4th and 5th processes, and the blanked plates are also taken out in  the same way as mentioned above. Unnecessary remaining parts 6 and 6A of the  raw material are blown off in the direction in which the raw material is fed by compressed air jetted out through nozzles 15 and 15A at the same tine when the top mold is raised. At this time, the remaining part 6 are fenced by a partition 17 whose upper part is always fitted to the stripper of the upper mold, so that the remaining parts are not blown off to the right side, and thus the remaining parts are removed.
