Abstract: A method for manufacturing a resin pipe joint with a joint body includes the following steps. Preparing a mold and a supply device configured to supply molten resin. The mold includes a first mold for an outer shape of the joint body and a second mold for an inner shape of the joint body. Combining the second mold with the first mold to form a cavity, into which the molten resin is injectable, inside the mold. Supplying the molten resin to the cavity in the mold. Solidifying the molten resin in the cavity after stop of the supply of the molten resin from the supply device. The second mold has a gap that connects the cavity to a discharge space outside the cavity and allows gas to flow.

Abstract: Provided is a coating base material having a new configuration capable of enhancing the durability of a coating regardless of the adhesion strength of a primer. A coating base material 1 whose surface is subjected to application of a coating includes: a mesh-like valley portion 2 formed on the surface; and a plurality of island portions 3 formed on the surface and surrounded by the valley portion 2. Each island portion 3 has a crater-like recess 4 formed on an upper surface thereof.

Abstract: A bellows pump device includes first and second bellows mounted on a pump head so as to be expandable/contractible independently of each other and configured to suck a fluid from a suction passage thereinto by expansion thereof and discharge the fluid therefrom to a discharge passage by contraction thereof. First and second air cylinder portions are configured to respectively cause the first and second bellows to perform expansion/contraction operation. First and second detection devices are configured to detect expanded/contracted states of the first and second bellows, respectively. A control unit is configured to control drive of the first and second air cylinder portions on the basis of each of detection signals of the first and second detection devices such that, before one bellows comes into a most contracted state, the other bellows is caused to contract from a most expanded state.

Abstract: A pipe connecting device having a joint body including a fitting cylinder to which a flared synthetic resin-made tube is to be externally fitted, an external thread formed on a radially outward side of the fitting cylinder; and a union nut including an internal thread screwed with the external thread, and a tube pressing portion that presses a diameter changing portion formed between a flared portion in the tube, and a non-flared portion, in the direction of the axis. In a fastening completion state in which the tube pressing portion is caused to press the diameter changing portion by a screw advancement of the union nut, the screw advancement being produced by screwing the internal thread to the external thread, positions of a basal end of the external thread and a tip end of the union nut in the directions of axes coincident with each other.

Abstract: A synthetic resin-made welding joint that has a pipe end portion into which an end portion of a synthetic resin-made tube is to be fitted and inserted, and that is configured so that the pipe end portion and the tube end portion which is fitted and inserted thereinto are enabled to be welded together by heating of heating means which externally surrounds the pipe end portion, therefore, a synthetic resin-made holder which is fitted and attached onto the pipe end portion is disposed, and a flange for ensuring a radial expansion gap with respect to the heating means is integrally formed in the holder.

Abstract: A fluid apparatus includes a bellows that is configured to be extendable and contractible in an axial direction in order to suck a fluid from a suction flow passage and eject the fluid to an ejection flow passage. The bellows has peak portions and valley portions, which are alternately formed in the axial direction, and annular side surface portions, which are located between the peak portions and the valley portions and connect the peak and valley portions to each other. A ratio B/A of the thickness B of the axial middle part of each of the peak portions in a direction which is perpendicular to the axial direction, to the thickness A of each of the side surface portions in the axial direction is set within a range of 1.3 to 1.8.

Abstract: A resin pipe joint including: a synthetic resin-made joint body including an inner cylinder portion, an external thread portion, and a radial groove m into which an end of a tube enters; and a union nut that is made of a transparentable fluorine resin, and the union nut including an internal thread portion, a seal peripheral edge which presses a tip end portion of a tube flared portion, a slipping-off prevention peripheral edge which is actable on a large-diameter portion of a flaring changing region, and a pressing inner peripheral portion which is externally fittable to a flared straight portion.

Abstract: In a resin pipe joint having a configuration where, by a screw advancement of a union nut caused by screwing an internal thread to an external thread in a state where a tube is externally fitted to an inner cylinder to form a flared portion, a flaring changing region is pressed by a seal pressing portion, a torque varying portion in which projecting portions of a joint body and recess portions of the union nut are fitted to or unfitted from each other by a flexural displacements of the projecting portions in the direction of the axis in accordance with fastening rotation of the union nut from the vicinity of a portion in front of an end of the screw advancement, the screw advancement being caused by pressing of the seal pressing portion against the flaring changing region is configured.
