摘要： A gasket includes a first slope at a first axial end. The fluid device includes a second slope that contacts the first slope. The first slope and the second slope have different gradients. The first slope allows at least the first axial end to be deformed along the second slope. The first slope contacts the second slope with a gradient that varies depending on a gradient of the second slope to seal a gap between the first slope and the second slope.

摘要： A diaphragm pump includes a reciprocable diaphragm, an actuator including a motor, and a control device. The control device resets an origin of the diaphragm in a reciprocating direction, when detecting a step-out of the motor. After resetting the origin, the control device activates the actuator to move the diaphragm to the origin.

摘要： A diaphragm pump has: a housing; a piston; a shaft; a rolling diaphragm, which is configured so that a lid portion reciprocally moves integrally with the piston; a driving device, which can convert rotational movement of a motor section to linear movement, and output the linear movement from an output axle to the shaft; a guiding member; and a restricting mechanism. The guiding member is placed on another axial end side of an interior of the housing with respect to the piston, attached to the housing, and able to guide the shaft movably in the axial direction. The restricting member is disposed in the housing and between the guiding member and the shaft, and able to restrict rotation of the shaft about the axis while allowing reciprocal movement in the axial direction.

摘要： An antistatic cover which, when the cover covers an insulating resin-made tube, can enhance the certainty of preventing the tube from being electrically charged, and can facilitate attachment to and detachment from the tube. The tubular cover body, is divided in a circumferential direction to form first and second divided portions. The cover body is elastically deformed such that the first and second divided portions separate from each other, and allow the tube to pass through between the first and second divided portions. The cover body has a plurality of first cutaway portions, which pass through at least one of the first and second divided portions in a radial direction of the cover body, and is configured such that, when the cover body is fitted onto the tube, a part of the tube can be exposed through the plurality of first cutaway portions.

摘要： An inner ring 4 of a pipe joint 1 includes a cylindrical body portion 5 having a communication hole 5a for providing communication between flow passage holes 2c and 8a of a joint body 2 and a tube 8, and an annular primary sealing portion 11 projecting from a radially inner side of an axially outer end portion of the body portion 5 toward an axially outer side and to be press-fitted into an annular primary sealing groove 2d formed on the joint body 2. The primary sealing portion 11 is formed so as to be tapered from an axially inner end thereof toward an axially outer end thereof in an axial cross-sectional view, and has a flat surface 11c extending from a radially outer end 11b of the axially outer end thereof toward the radially inner side.

摘要： A bellows pump device includes a control unit which, before operation of the bellows pump device is started, performs initial control in which solenoid valves are switched and pressurized air is supplied to suction-side air chambers in advance, thereby determining operation air pressures which are air pressures of the pressurized air to be supplied to the suction-side air chambers during the operation. As the initial control, the control unit outputs control commands to electropneumatic regulators so as to gradually increase the air pressures of the pressurized air to be supplied to the suction-side air chambers in advance, and when detection signals resulting from detection of expansion positions of the bellows are inputted from the proximity sensors to the control unit, the control unit determines the air pressures of the pressurized air supplied to the suction-side air chambers at that time as the operation air pressures.

摘要： A pipe joint includes: an inner ring having a bulge portion to be press-fitted into an end portion of the tube; a joint body having an inner circumference into which an end portion of the inner ring is to be press-fitted, and having an external thread portion on an outer circumference thereof; and a union nut having an internal thread portion to be tightened to the external thread portion, and configured to press the end portion of the tube when the internal thread portion is tightened to the external thread portion. The bulge portion has a tapered portion configured to generate a surface pressure between the tube and the tapered portion by pressing by the union nut. An outer circumferential surface of the tapered portion has a concave surface portion formed in a concave surface shape in an axial cross-sectional view.
