Abstract: A power conversion apparatus includes: a three-phase inverter that supplies alternating-current power obtained by conversion to a load via a filter circuit including a three-phase reactor circuit and a three-phase capacitor circuit; a voltage detector that detects three-phase voltages that are voltages at respective connection points between the three-phase reactor circuit and the three-phase capacitor circuit; and a control device that controls operation of the three-phase inverter on the basis of the three-phase voltages detected by the voltage detector. The control device includes a calculation unit that calculates a zero-phase voltage obtained by adding together the three-phase voltages, a separation unit that separates an instantaneous value of the zero-phase voltage into an alternating-current signal and a direct-current signal, and a first determination unit that determines whether a ground fault occurs on the basis of an effective value of the alternating-current signal.

Abstract: A power conversion device includes a converter and an inverter that form a power converter to convert a first power into a second power, an input-current sensor to measure a first current value that is a current value of the first power, an output-current sensor to measure a second current value that is a current value of the second power, and a control unit to detect an abnormality of the input-current sensor based on the first current value and the second current value.

Abstract: It is intended to provide a cancer metastasis inhibitor which shows a potent effect of inhibiting cancer metastasis comparable to bikunin, has no side effect and can be obtained in a large amount at a low cost. As the results of studies on the cancer metastasis inhibitory effect by administration of soybean Kunitz trypsin inhibitor (KTI), a potent activity of inhibiting cancer metastasis was found out. Since KTI is contained in soybean whey, which is yielded in a large amount in preparing isolated soybean protein and the like from soybeans, and soybean whey can be obtained at a low cost, KTI extracted and purified in a large amount from soybean whey is clinically applicable.

Abstract: The invention provides a process for producing a baked food of wheat flour by using a soybean protein in which NSI shows a low denature value of 40 or more, the content of solid component extracted with a solvent mixture of chloroform and methanol (2:1) is 2.0 wt % or less, and the crude protein content is 63% or more. When wheat flour in dough is replaced with the soybean protein at a small ratio, baked foods of wheat flour which are resistant to freezing and show good texture even after thawing in a microwave oven can be obtained. Moreover, a process for making a baked food mainly comprising soybean proteins, which has a good taste and texture and is appropriately taken by human, can be provided by replacing most part or all of wheat flour with a soybean protein.

Abstract: The present invention is directed to 3-benzoylindole derivatives represented by the following formula (I): (wherein R1 represents a lower alkyl group, n is an integer from 1 to 5; each of R2 and R3 represents a hydrogen atom, a lower alkyl group, or an optionally substituted phenyl group; and R4 represents a hydrogen atom, a lower alkyl group, or a benzyl group) and to a pharmaceutical containing the same. This compound is endowed with strong &agr;1-adrenergic receptor blocking action and strong testosterone 5&agr;-reductase inhibitory action, as well as high level of safety, and thus is useful as an excellent preventive or therapeutic drug for prostatic hypertrophy or accompanying urination disorder, alopecia, and acne.

Abstract: A process for manufacturing a photoreceptor for electrophotography excellent in electrophotographic characteristics such as charging properties and sensitivity, which process comprises the steps of forming on a substrate, which comprises an electroconductive support or a support having an electroconductive film thereon, a thin film composed of a material selected from the group consisting of silicon dioxide and silicon oxides, containing predominantly SiO.sub.2, by deposition from the vapor phase to produce an under coat layer, and forming on said under coat layer a carrier generation layer and a carrier transport layer in this order.
