The invention relates to a butt welding machine adjusting the ends of plastic pipes and welding them to each other, which comprises a cutter having a driving element for moving the trimmer by being driven, at least one movable claw, moving depending on a connector to hold pipes which are positioned, a motor which does not have direct connection with the cutter and transfers power to the cutter and to the movable claw via one connector for each, a cutter which needs to be had two different driving motion performed via two different connectors, a drive gear unit providing driving energy to the movable claw from one point.

A sheet bonding device includes a pressurization mold which is constituted of an upper mold and a lower mold and performs sealing through heating by sandwiching a sealing target portion of a bag main body and a sealing target portion of a gas barrier function sheet with pressurization surfaces; a plurality of support pins which are provided in the lower mold so as to be retractable and position the gas barrier function sheet with respect to one surface of the bag main body by penetrating the sealing target portions of the bag main body and the gas barrier function sheet; and gas spray means for making the gas barrier function sheet float by spraying inert gas to an area-enlarged portion, which does not overlap the bag main body, of the gas barrier function sheet supported by the support pins.

A resin end-face butt joint, a method for welding the joints, and a piping member ensure a sufficient clamping margin with the clamp of an ordinary welding machine, and ensure an appropriate distance between the centers even when joints having short tubular welding ring parts are welded. It is also possible to align the centers by positioning the centers along the same axis. The resin end-face butt joint includes multiple welding ring parts which communicate with a flow path within a joint base part and which are provided on the joint base part. Fastening parts are coaxial with at least one of these welding ring parts at the outer end of the joint for the purpose of clamping a welding machine.

Systems and methods for controlling a pump system for use in negative pressure wound therapy are described herein. In some embodiments, a method for controlling a pump system includes causing provision of negative pressure, via a flow path, to a wound dressing configured to be positioned over a wound, the flow path configured to fluidically connect the pump system to the wound dressing, measuring a first pressure value in the flow path at a first time, measuring a second pressure value in the flow path at a second time, calculating a first rate of pressure change using the first and second pressure values, and in response to determining that the calculated first rate of pressure change satisfies a threshold rate of change, providing an indication that the wound dressing is full, wherein the method is performed under control of a controller of the pump system.

A system for ultrasonic or vibration welding, staking, swaging, forming or degating of a thermoplastic workpiece includes a vibratable horn having a face, a thermoplastic workpiece, and a vibratable tool positioned between the vibratable horn and the thermoplastic workpiece. The system is configured to energize the vibratable horn to transfer energy from the vibratable horn through the vibratable tool to the thermoplastic workpiece to induce welding, staking, swaging, forming or degating of the thermoplastic workpiece. Optionally, the upper and/or lower surfaces of the vibratable tool may have three-dimensional contour(s) that are complementary to three-dimensional contour(s) of the vibratable horn and/or the thermoplastic workpiece. Additional systems and methods for ultrasonic or vibration welding, staking, swaging, forming or degating of a thermoplastic workpiece are also disclosed.

A tubular body formed by joining two semi-tubular portions that are divided in radial direction, the tubular body having a connection flange portion provided with a bolt hole on at least one end portion. The two semi-tubular portions have joint projection portions at both edge portions in circumferential direction, the joint projection portions projecting in radial direction and extending in axial direction, and each joint projection portion of the semi-tubular portions on at least one of both sides in circumferential direction is configured to be bent so as to deviate from a virtual division face passing a central axis in such a manner that a joint portion formed by abutting the joint projection portions does not interfere with a tool for fastening a bolt inserted into the bolt hole in a predetermined area in the vicinity of the bolt hole of the connection flange portion.
