Abstract: A hand dryer device includes nozzles to blow airflows into a hand-placeable drying portion, a blower to generate the airflow to be blown out of the nozzles, a sensor having a light-emitting element to detect the presence or absence of a hand in the drying portion, and a controller to make a hand detection determination of whether the hand is present or absent in the drying portion based on a detection result of the sensor, and control driving of the blower based on a determination result of the hand detection determination. The controller controls an intermittent driving of the light-emitting element of the sensor. In first and second driving cycles of the sensor, when a determination result in the first driving cycle and a first determination result in the second driving cycle differ from each other, the controller extends a driving period of the sensor in the second driving cycle.

While one of the capacitance-detection-type proximity sensor structures is in operation, an operation of at least another of the capacitance-detection-type proximity sensor structures is stopped to operate the capacitance-detection-type proximity sensor structures during different periods of time.

Abstract: This invention provides a nonhuman transgenic mammal carrying transgene comprising the regulatory genes capable of functioning in the hyperacute rejection-occurring local cells and gene encoding human N-acetylglucosaminyltransferase III (GnT-III), or a nonhuman transgenic mammal carrying transgene comprising the regulatory genes and genes encoding GnT-III and the human complement inhibitor. Because of reduced ?-Gal antigens in the hyperacute rejection-occurring local cells or because of both reduced ?-Gal antigens and expression of the human complement inhibitor, the transgenic mammal of this invention can effectively inhibit the hyperacute rejection caused by discordant xenotransplantation. Consequently, this invention provides the transgenic mammal suitable for organ transplantation.

Abstract: The invention presents a swine cell not expressing ?-1,3-galactosyl transferase and expressing human complement inhibitor and/or human N-acetyl glucosaminyl transferase III; a method of selecting the same; and a swine for xenotransplantation. The swine for xenotransplantation of the invention is very useful in inhibiting the acute rejection characteristic to xenotransplantation because it does not express ?-Gal antigen but inhibits the progress of a complement reaction, if unexpectedly induced, and/or expresses little xenoantigen other than ?-Gal antigen.

Abstract: A diagonally joined cylindrical fabric in the form of a cylindrical endless fabric is obtained by shifting ends of facing wefts of a non-endless fabric leftward or rightward and joining together the ends of the wefts to thereby form a joining portion inclined relative to an axis of a cylinder. The cylindrical fabric comprises a weave pattern in which warp passes over continuous two or more wefts, then passes under a less number of wefts, the joining portion at ends of the fabric formed into an endless cylindrical shape is inclined relative to the axis at 25° to 5°. The surface of the cylindrical fabric is formed with crimps that are longer in a face length direction than in a circumferential direction.

Abstract: This invention provides transgenic mammals other than man carrying the gene of the human complement inhibitor (DAF/CD55) and expressing the human complement inhibitor in their organs and tissues, particularly in their endothelial cells. This invention provides nonhuman transgenic mammals useful as laboratory animals in the medical and pharmacological fields and/or sources of organs, tissues, cells and the like for medical treatment of man.

Abstract: This invention provides a nonhuman transgenic mammal carrying transgene comprising the regulatory genes capable of functioning in the hyperacute rejection-occurring local cells and gene encoding human N-acetylglucosaminyltransferase III (GnT-III), or a nonhuman transgenic mammal carrying transgene comprising the regulatory genes and genes encoding GnT-III and the human complement inhibitor. Because of reduced &agr;-Gal antigens in the hyperacute rejection-occurring local cells or because of both reduced &agr;-Gal antigens and expression of the human complement inhibitor, the transgenic mammal of this invention can effectively inhibit the hyperacute rejection caused by discordant xenotransplantation. Consequently, this invention provides the transgenic mammal suitable for organ transplantation.

Abstract: The present invention provides the base sequence defined as Sequence No. 1, DNA comprising a part of the sequence, or DNA containing the sequence, and relates to a promoter gene of the porcine complement inhibitor. In generating transgenic pigs transformed with human complement inhibitor and/or such thrombosis-inhibiting factors as thrombomudulin (collectively termed the complement inhibitor), DNA of the invention can effectively be used to express the complement inhibitor by integrating the gene into the upstream part of the human complement-inhibitor gene. Since hyperacute rejection, which occurs on transplanting a porcine organ or tissue to man, can be prevented, xenotransplantaion of the porcine organs and tissues to man will become possible. Therefore, the problem of the lack of donors for transplantation can be solved.
