Title: X-ray irradiation crystallization method and crystallization device
Inventor: SATO SHIRO
IPC: H01L21/26
Filed: 1993-12-16
Abstract: PURPOSE:To crystalline an amorphous thin film at a relatively low temperature in a short time by irradiating X-ray which has photon density exceeding a specified threshold value and enables inner shell excitation of an amorphous thin film constituent atoms on an amorphous thin film. CONSTITUTION:A sample which is formed by doping a silicon single crystalline substrate with a large amount of arsenic for realizing an amorphous surface is attached to a tip of a transfer rod 4. The transfer rod 4 is inserted into a return yoke 23 and a sample 5 is mounted on a position 0.7m apart from a light source point and irradiated with SR light. In the process, crystallization starts abruptly when photon density exceeds 6X10<15>/s.mm<2>. Therefore, photon density should be more than a fixed threshold value for causing crystallization. On the contrary, if photon density is high, crystallization occurs even about 10 minutes. Therefore, an amorphous thin film can be crystallized at a relatively low temperature and in a short time.

IPC: D21F9/02
Filed: 1992-11-26
Abstract: PURPOSE:To provide the subject dehydrating unit good in resistance to corrosion and wear. CONSTITUTION:The objective dehydrating unit is so designed as to slide with one surface of a papermaking wire to control the dehydration from the pulp liquor on the other surface. The part to be contacted with the papermaking wire consists of an alloy prepared by calendering and heat-treating an Ni alloy having a composition comprising 14-23wt.% of Cr, 14-20wt.% of Mo, 0.2-5wt.% of W, 0.2-7wt.% of Fe, 0.2-2.5wt.% of Co and the balance Ni with inevitable impurities. By this constitution, sufficient hardness of this alloy can hold high wear resistance and corrosion resistance against sulfates and sodium hydroxide in pulp liquor. Besides, as the alloy has been put to intense calendering, its structure is fine, leading to little wearing of the papermaking wire as the counterpart for sliding. Furthermore, because the alloy is a material obtained by calendering, a continuous material can easily be obtained.
