Abstract: A manufacturing device is used for manufacturing a package including a resin sheet and a predetermined work wrapped with the resin sheet. The manufacturing device includes: a sealing unit that thermally welds overlapping parts of the sheet; and an inspection device that inspects a sealing quality of the sealed portion thermally welded by the sealing unit. The sealing unit makes, by the thermal welding, a thickness of the sealed portion after the thermal welding smaller than a total thickness of the overlapping parts prior to the thermal welding. The inspection device obtains thickness information on the thickness of the sealed portion and determines the sealing quality of the sealed portion based on the thickness information.

Abstract: An inspection device includes: an irradiator that radiates, before content is placed into the pocket, ultraviolet light toward one face of the container film; imaging devices that take images of the container film from another face side of the container film; and a processor that determines, based on the images, whether the pocket includes a pinhole, at least two of the imaging devices being each disposed on respective sides of the container film in a width direction such that the pocket is placed between the two imaging devices, and while the container film is being conveyed along a conveyance path, the two imaging devices take images of the pocket at a timing when the pocket is located at an upstream-side position, a middle-side position, and a downstream-side position of the conveyance path.

Abstract: A solenoid unit of an electromagnetic valve includes a coil, a bobbin, a fixed iron core, a movable iron core, an urging spring, a magnetic frame, and a molded plastic part. The magnetic frame includes a frame end wall, two frame arms, and an internal thread hole, to which the fixed iron core is threaded. A tubular projection protrudes from an end face of the frame end wall that is on a side opposite to the bobbin. The projection forms part of the internal thread hole. The molded plastic part includes a molded end wall, which covers the frame end wall, and a molded peripheral wall. The molded end wall includes a connecting hole that is continuous with the internal thread hole. The connecting hole includes a groove in an inner circumferential surface. The groove extends along an outer circumferential surface of the projection.

Abstract: A vacuum pressure proportional control valve placed on a pipe connecting between a reaction vessel and a vacuum pump to control the vacuum pressure in the reaction vessel includes a cylinder provided with a piston chamber, a piston housed in the piston chamber so as to make reciprocal linear movement, a valve seat surface, and a valve element which contacts with or separates from the valve seat surface according to the movement of the piston. A stopper member is provided in the cylinder so that a leading end portion of the stopper member is placed in the piston chamber. The stopper member is configured to move the piston back and forth in a moving direction of the piston by use of an adjusting unit to thereby adjust the position of the leading end portion.

Abstract: A butterfly valve includes a drive unit and a valve unit that are coupled to each other. The drive unit includes a hollow part in which a rod is inserted between a DD motor and an end portion of the drive unit on a coupling side to the valve unit. In the hollow part, a cylindrical magnetic member is placed coaxially with the rod to cover the outer peripheral surface of the rod. A magnetic fluid is filled in a void between the outer peripheral surface of the magnetic member and the inner peripheral surface of the hollow part. The rod is made of a non-magnetic corrosion-resistant alloy.

Abstract: A three-dimensional measurement device performs three-dimensional measurement of a measured object using a phase shift method. The three-dimensional measurement device includes: an irradiator that irradiates the measured object with a predetermined light pattern having a light intensity distribution in a fringe shape; a control device that shifts a phase of the light pattern radiated from the irradiator in N different ways, where N is a natural number of not less than 3; and an imaging device that takes an image of the measured object irradiated with the light pattern. The control device executes three-dimensional measurement of the measured object by the phase shift method based on N different image data taken under the light pattern having the phase shifted in the N different ways.
