Background. We investigated retrospectively the usefulness of polysaccharide K (PSK) administration for prolonging survival after noncurative resection in patients with stage IV gastric cancer who underwent surgery at our department. Methods. 357 patients with gastric cancer evaluated as stage IV according to thegeneral rules for gastric cancer study, 11th(More)
An increase in the sheet resistance at small diffusion regions is caused by the formation of high resistivity phases of nickel silicide. The increase in the sheet resistance strongly depends on the size of diffusion region at which nickel silicide is formed. On the condition under which NiSi is formed at large diffusion regions, Ni<sub>3</sub>Si<sub>2</sub>(More)
La<sub>3</sub>Ta<sub>0.5</sub>Ga<sub>5.5</sub>O<sub>14</sub> (LTG) single crystals, which have no phase transition up to the melting point, were heat treated in air at temperatures from 1000&#x00B0;C to 1450&#x00B0;C for 10 h. LaTaO<sub>4</sub> (LT) and LaGaO<sub>3</sub> (LG), which coexist with LTG in the three-phase region on the Ga-poor side,(More)
The compressive stress distribution below the specimen surface of severely surface deformed steels by shot peening was investigated by using laboratory X-rays and high-energy X-rays from a synchrotron radiation source, SPring-8 in the Japan Synchrotron Radiation Research Institute. Medium carbon steel plates were heat treated in two different conditions.(More)
Furnace anneal for the first anneal dramatically improves the uniformity of the sheet resistance of nickel silicide at small area. The main cause of the deterioration in the uniformity of the sheet resistance is not the crystalline state or the implanted impurities but the size of the pattern which nickel silicide is formed at.
