摘要:
In an internal combustion engine, an NOx selective reduction catalyst is arranged in the engine exhaust passage and a urea aqueous solution stored in a urea aqueous solution tank is fed to the NOx selective reduction catalyst where the NOx is selectively reduced. Opening and closing of the urea aqueous solution refill port of the urea aqueous solution tank are detected and it is judged if the urea aqueous solution is refilled in the urea aqueous solution tank. When it is judged that the NOx purification rate has fallen to an allowable level or less at the time of engine operation right after the urea aqueous solution is refilled in the urea aqueous solution tank, it is judged that the refilled urea aqueous solution is abnormal.

摘要:
A method for fabricating a semiconductor device is disclosed. The semiconductor device includes a capacitor and a support insulator. The capacitor includes a cylindrical electrode. The cylindrical electrode comprises upper and lower sections. The lower section has a roughened inner surface and an outer surface supported by the support insulator. The upper section upwardly projects from the support insulator. An initial cylindrical electrode is formed, wherein the initial cylindrical electrode comprises an initial upper section and an initial lower section which correspond to the upper section and the lower section of the cylindrical electrode, respectively. The initial upper section is supported by the support insulator. Specific impurities are implanted into the initial upper section, wherein the specific impurities serve to prevent the initial upper section from being roughened. Then, the initial cylindrical electrode is exposed to a roughening process so that the initial lower section is roughened to be the lower section.

Characterized by checking, after stopping a stocker driving motor, whether a target pattern can be detected at the stopping position or not; and by reducing, if the target pattern cannot be detected at the stopping position, the driving force of the stocker driving motor during retrying operation carried out by reversing the rotation of the stocker driving motor.
摘要:
A probiotic lactobacillus was discovered from lactobacilli of the Lactobacillus genus independently isolated from human adult feces. The probiotic lactobacillus was selected from other bacterial strains for: (1) being highly resistant to gastric acid/bile acid; (2) having a high promoting activity on IL-12 production from mouse derived spleen cells and a high Th1/Th2 balance-improving effect; (3) having a high ability to inhibit the production of antigen-specific IgE induced by intraperitoneally administering ovalbumin to BALB/c mice; (4) having a high ability to inhibit the production of antigen-specific IgE induced by orally administering a food antigen to C57BL/6N mice; (5) having a high Natural Killer cell-activating ability; (6) having a high IL-12 production-promoting activity on spleen cells and mesenteric lymph node cells derived from mice immunized with ovalbumin and a high Th1/Th2 balance-improving effect; and (7) having a high ability to suppress eosinophilia induced by a cedar pollen-extracted antigen. This discovery led to the completion of the present invention.

摘要:
A noncontact voltage sensor is housed in a container comprising a container body having an opening on one side and an insulation cover body for sealing the opening. A plate type electrode insulated from a ground is housed in the container. The cover body side is opposed to a charging part of such as cables of an aerial line. A voltage is induced in the plate type electrode due to aerial electric charges between the charging part and the plate type electrode in the container, allowing detection of the voltage in the charging part. The cover body of the noncontact sensor is made of a fluorine containing resin such as an ethylene tetrafluoride resin to prevent a water film from forming on the outside surface of the insulation cover body and causing deterioration of the detection.
