Abstract: Magnetic material powder that can be detected by a metal detector and the like and tungsten powder that can be detected by an X-ray inspection device are dispersed in a polymer material of the molded article.

Abstract: A liquid sensor comprising a laminate including a first conductive layer, an insulation layer, and a second conductive layer layered in this order, wherein the laminate has through holes penetrating the first conductive layer, the insulation layer, and the second conductive layer in the lamination direction, and the first conductive layer and the second conductive layer are layers of a resin having electrical conductivity.

Abstract: The present invention relates to a gasket for a food processing plant, a piping joint structure for a food processing plant using the gasket and an O-ring for a food processing plant.

Abstract: A spacer is disclosed in which a retaining portion of a product being conveyed is not generated even if the product being conveyed in a hose has high pressure or an inner pressure of the hose is high. The spacer includes a cylindrical body. The cylindrical body is cut along a shortest line on an outer periphery surface of the cylindrical body which connects a point on an end of the cylindrical body with a point on the other end of the cylindrical body and which is not parallel to an axis of the cylindrical body. The cut cylindrical body is interposed between a hose band for tightening an outer periphery of the end of the hose under a state that the end of the hose is put onto a hose joint.

Abstract: A tool for assisting spray work at a high position which includes a pole, a holder for holding a spray device at an upper portion of the pole, a valve-opening mechanism for opening an ejecting valve of the spray device, and an operating mechanism for remotely operating the valve-operating mechanism from a lower portion of the pole. The holder for holding the spray device at an upper portion of the pole includes an upper holder fixed on the upper end of the pole, laterally extending and having a fitting portion for holding a neck portion of the spray device, and a lower holder having a tubular portion slidably mounted on the pole, an arm laterally extending from the tubular portion, and a receiving portion provided at a free end of the arm. The receiving portion supports the lower center surface of the spray device. A clamping mechanism is provided for fixing the tubular portion on the pole.

Abstract: A tool for assisting spray work at a high position which includes a pole, a holder for holding a spray device at an upper portion of the pole, a valve-opening mechanism for opening an ejecting valve of the spray device, and an operating mechanism for remotely operating the valve-operating mechanism from a lower portion of the pole. The pole can be telescopic with a rigid wire rod running therethrough. A chuck mechanism at the lower portion of the pole catches the wire rod when the operating mechanism is operated.
