Title: Flocculant for treating tap water
Inventor: IWANE NOBUO
IPC: C01G23/00
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To largely reduce turbidity after treatment and to conserve the use amt. of an alkali auxiliary agent by adding titanyl sulfate as a flocculant of tap water in a specific ratio with respect to tap water in terms of the concn. of TiO2 . SOLUTION: When titanyl surfate is added to raw material water for tap water, it is dissolved in water in a crystal state to be used as a 5-15% aq. soln. and the prepared aq. soln. is added to raw material water for tap water so as to become a ratio of 5-20ppm in terms of the concn. of TiO2 . Ions of Ti and H2 O formed by partial hydrolysis of titanyl sulfate form a polynuclear complex and these components become main to be flocculated as a flocculant of tap water to generate floc and, finally, turgidity is effectively removed. By this constitution, when the titanyl sulfate aq. soln. is used as the flocculant for tap water, turbidity after treatment can be reduced and a use amt. of an alkali auxiliary agent can be saved.

IPC: H01L21/223
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To form a diffusion layer of high quality with good reproducibility by mount ing a specimen and a diffusion source, without the use of quartz ampoule in a labor- saving manner, in an equipment diffusing impurity elements in a semiconductor crystal wafer. SOLUTION: A semiconductor crystal wafer 22 and a diffused source 23 are arranged in a diffusion equipment, and the entire is covered with a lid 21 made of quartz. In this structure, diffusion (heat treatment) is performed. The contact part of the lid 21 and the reference surface 26 of the equipment constitute a line contact structure. By pressing the contact part from the outside, the internal pressure at the time of diffusion is prevented from leaking to the outside. For quick heating and cooling in the diffusion process, a heating part and a specimen diffusion part 20 are movable. Since the structure, wherein the specimen and the diffusion source 23 are covered with the lid 21 made of quartz is used, the preliminary process is labor-saving and cost reduction is realized. Since the lid 21 and a diffusion jig can be used repeatedly, diffusion is enabled at low running cost.  The specimen is arranged sufficiently distant from the diffusion source 23, and diffusion can be performed by temperature change of quick heating and cooling with an optimum temperature profile, so that a diffusion layer of high quality can be formed.

Abstract: PROBLEM TO BE SOLVED: To prevent a gas sensor from being corroded by a silicone and to enhance its moisture resistance by a method wherein an opening is formed only in one side on the outer circumference of a metal oxide semiconductor film and other circumferential sides are covered with a glass film. SOLUTION: Three circumferential sides of a metal oxide semiconductor film 12 are covered with a glass film 14, and an opening 16 is left in one side. In addition, a glass whose MgO content is at 2wt.% or lower is used as the glass film 14. When the opening 16 is formed only in one side of the semiconductor film 12, it is possible to prevent a corrosive substance from creeping and from being accumulated and to enhance a corrosion-resistant property. In addition, the response characteristic of a gas sensor is hardly dropped. When the MgO content in the glass film 34 is set at 2wt.% or lower, its durability to a high-temperature and high-humidity atmosphere is enhanced. In addition when an SiO2 content in the semiconductor film 12 is set at 1wt.% or lower, its durability to the high-temperature and high-humidity atmosphere is enhanced further.
