Title: Setting method for x-ray diffraction goniometer
Inventor: TOIKAWA FUJIYUKI
IPC: G01N23/20
Filed: 1990-01-24
Abstract: PURPOSE:To widely attenuate X-ray strength near a shortest wave and to execute goniometer setting work with high accuracy by attenuating an X-ray direct beam by using an X-ray absorption board composed of the same material as a target. CONSTITUTION:As an example, when the absorption board composed of copper is used to a copper target, in a quantity absorption coefficient curve 28 of copper, an absorption end 30 is positioned at a wavelength slightly smaller than characteristic X-rays Kalpha and Kbeta. When the X-ray direct beam is attenuated by using this copper absorption board, a spectrum like a second figure is obtained. Namely, the X-ray strength is widely attenuated at a place, where the wavelength is smaller than the characteristic X-ray, and is not so much attenuated near the characteristic X-ray. Therefore, a fluctuation area 32 for the X-ray strength near the shortest wave does not exert an influence upon total X-ray strength to much. Thus, when the copper absorption board is used to the X-ray tube of copper target, the time fluctuation of the X-ray strength hardly occurs at the time of goniometer setting and the accurate setting work is executed.

Title: Superconducting magnet
Inventor: SONOBE TADASHI
IPC: H01L39/04
Filed: 1993-01-28
Abstract: PURPOSE:To prevent occurrence of quenching of a permanent current switch by incorporating two sets of the switches in refrigerant for one permanent current switch. CONSTITUTION:Two sets of permanent current switches 20a, 20b for energizing/ deenergizing two adjacent superconducting coils are contained in one refrigerant box 2 for the switch. Thus, when the two sets of the adjacent switches 20a, 20b are contained in the one box 2, the size of the box 2 is increased as compared with the one box when the individual boxes are contained as prior art. Thus, since a natural frequency of the box 2 is increased, it is not deviated from an operating frequency of a moving body placed with a superconducting magnet to prevent resonance, and hence quenching of the switches 20a, 20b can be prevented.
