Abstract: In a pressure/temperature sensor, a sensor circuit is held by a holding member inside a tube that is fixed to a pipe, and an introduction portion is provided in the holding member at an inner side of the pipe with respect to the sensor circuit. The introduction portion includes a plurality of blades having blade surfaces extending along a protrusion direction of the introduction portion with respect to the sensor circuit. The plurality of blades are arranged radially on a surface perpendicular to the protrusion direction, and angles defined by the blade surfaces of the adjacent blades are all acute angles. Thus, regardless of the angle at which the blade is attached with respect to the flow direction of the measuring medium, an acute-angled portion of any adjacent blades is directed to the flow direction of the measuring medium. Therefore, a pressure loss of the measuring medium can be reduced.

Abstract: A pressure/temperature sensor includes a sensor circuit configured to detect a pressure and a temperature of a measuring medium in a pipe, a holding member configured to hold the sensor circuit to be positioned inside a tube fixed to the pipe, and an introduction portion provided in the holding member to be positioned at an inner side of the pipe with respect to the sensor circuit. The introduction portion includes a plurality of blades having blade surfaces extending along a protrusion direction of the introduction portion with respect to the sensor circuit. The plurality of blades are arranged radially on a perpendicular surface perpendicular to the protrusion direction, and angles defined by the blade surfaces of the adjacent blades are all acute angles.

Abstract: The present invention provides removing agents comprising a solid substance with a weakly acidic or weakly alkaline surface. Since the removing agents can be used for treating body fluid of a patient by, for example, extra-corporeal circulation system thereby effectively removing human immunodeficiency virus and/or its related compounds contained in the body fluid, it is expected that the life of the patient could be prolonged. The significance of the present invention therefore is great.
