摘要:
A gas-liquid dissolving apparatus that dissolves an oxygen-containing gas into water taken in from an oxygen-deficient water area, increases a dissolved oxygen concentration of the water, and returns the increased dissolved oxygen concentration water to the oxygen-deficient water area is provided. The apparatus includes a pump 3 that takes in the water from the oxygen-deficient water area, an oxygen supplying unit 4 that supplies the oxygen-containing gas, an elongated cylindrical gas-liquid dissolving chamber 5 that has at least one hole 5b formed in a lower portion and that has a dome-shaped top plate 5a provided in an upper portion, a nozzle 2 that ejects the gas from the oxygen supplying unit 4 and the water from the pump 3 upward so that the gas and the water strike against an inner wall of the top plate 5a of the gas-liquid dissolving chamber 5, that vigorously agitates the gas and the water by forces of the ejected gas and water, and that has a tip end having a tapered inside, a gas-liquid separating chamber 6 that communicates with the gas-liquid dissolving chamber 5 through the hole 5b, and that separates bubbles and the water flowing out from the gas-liquid dissolving chamber 5 through the hole 5b from each other while storing the bubbles and the water, and a water supply port 6b that returns the water separated from the bubbles to the oxygen-deficient water area.

The semiconductor device has a collector electrode, a p+ collector region formed on the collector electrode, an n− drift region formed on the collector region, a p− body region formed on the drift region, and a plurality of n+ emitter regions formed within the body region. The emitter regions are connected to an emitter electrode. A plurality of trench gate electrodes is formed within the body region. Each trench gate electrode opposes, via an insulating layer, a portion of the body region separating the drift region and the emitter region. The body region is divided into a plurality of body sections, and the body sections are classified into two groups. One group has the emitter region within the body section, and the other group has no emitter region within the body section. A plurality of first trenches is formed within the body section having no emitter region. A p+ contact region is formed between the first trench and the trench gate electrode.

The invention concerns GENSET polynucleotides and polypeptides. Such GENSET products may be used as reagents in forensic analyses, as chromosome markers, as tissue/cell/organelle-specific markers, in the production of expression vectors. In addition, they may be used in screening and diagnosis assays for abnormal GENSET expression and/or biological activity and for screening compounds that may be used in the treatment of GENSET-related disorders.

The present invention relates to the field of metabolic research. Metabolic disorders, such as obesity, are a public health problem that is serious and widespread. GSSP4 polypeptides have been identified that are believed to be beneficial in the treatment of metabolic disorders. These compounds should be effective for reducing cholesterol levels, body mass, body fat, and for treating metabolic-related diseases and disorders. The metabolic-related diseases or disorders include, but are not limited to, obesity, hyperlipidemia, hypercholesterolemia, atherosclerosis, diabetes, glucose intolerance, insulin resistance and hypertension.

A pressure sensor includes a semiconductor substrate having a diaphragm in which an electrical circuit including a gauge resistance is formed, an insulation film provided on a surface of the semiconductor substrate, an Al film provided on the insulation film and electrically connected to the electrical circuit through a conductor hole of the insulation film, an Au film provided on the Al film through a Ti film, a first protective film which covers the Al film and has an opening portion from which a portion of the Au film is exposed. In the pressure sensor, a second protective film made of polyimideamide or polyimide covers at least the surface of the Au film exposed from the first protective film, and a vicinity of the opening portion of the first protective film. Therefore, corrosion resistance of the Al film can be prevented while the pressure sensor has a reduced component number.
