Title: Production of raw material powder for permanent magnet material
Inventor: OOTA AKIYASU
IPC: H01F1/06
Filed: 1986-07-24
Abstract: PURPOSE:To safely and stably produce raw material powder for a permanent magnet material by coarsely crushing specifically composed raw material Fe-B-R ingots, occluding H2 therein to form coarsely crushed powder and pulverizing the powder by a supersonic inert gas contg. O2 at a specified ratio. CONSTITUTION:The ingots essentially consisting of 12-20atom% R (at least 1 kind among Nd, Pr, Dy, Ho, and Tb or further at least 1 kind among La, Ce, Sm, Gd, Er, Eu, Tm, Yb, Lu, and Y), 4-20atom% B, 65-81atom% Fe are crushed and H2 is occluded therein to cause natural decay and to form the coarsely crushed powder having 500-10mu average grain size. The coarsely crushed powder is then injected into a pulverizing chamber for gaseous flow pulverization using the supersonic inert gas contg. 50-6,000ppm O2 and is thereby pulverized to the fine raw material powder having 1.5-5mu average grain size. The fine powder is molded to a required shape and size by orientation in a magnetic field; thereafter, the molding is sintered in a vacuum and is allowed to cool. The molding is further subjected to an aging treatment in an Ar atmosphere, by which the permanent magnet material is obtd.

Title: X-ray generation device
Inventor: ARAI KATSUYUKI
IPC: G21K5/02
Filed: 1995-06-16
Abstract: PURPOSE: To provide an X-ray generation device, having the less attenuation of an X-ray, being usable for a soft X-ray too, excellent in airtightness, and moreover having an X-ray takeout window sufficient in strength. CONSTITUTION: An electron, emitted from a filament 8 in an electron gun 2, is made to collide with a rotor target 3 to form an X-ray focus F, and an X-ray is radiated from the focus F to take out a radiated X-ray outside through an X-ray takeout window 16. As for the window 16, since the thickness of an X-ray passing part in a center part, through which an X-ray is passing, is formed thin as a degree of 10-50μm, the attenuation of the X-ray, passing the X-ray passing part, can be inhibited. On the other hand, since the thickness of a ring-like peripheral part around the X-ray passing part is formed thick as a degree of 0.4mm, sufficient mechanical strength can be obtained to be correctly fixed over the whole inner peripheral surface region of a fixing flange 22 by soldering etc.
