    Abstract: Provided is an actuator including a ball-type thrust amplifier therein that controls a valve in which a high-pressure fluid flows, and having less wear between members and a long lifespan. This actuator for a valve includes a thrust amplification mechanism therein, in which the thrust amplification mechanism includes a disk, a ball presser, a stem, and a plurality of balls that are sandwiched by and in contact with an upper surface of the disk, a tapered surface of the ball presser, and a tapered surface of the stem and disposed to move outward as the stem moves downward, the surfaces of the parts constituting the thrust amplification mechanism are coated with grease containing an additive, and the additive of the grease includes at least chloroalkane.

    Abstract: Provided is a small-sized controller capable of precisely controlling a flow rate of a high-pressure fluid. Between a working shaft of a drive device and a valve stem, a power transmission device is disposed to amplify a force acting on the working shaft and transmit the resultant force to the valve stem. A diaphragm as a valve element is made of metal and is deformable to: a state where a fluid passage is fully closed; a state where the fluid passage is fully open; or a state where the fluid passage is partially open. When the fluid passage is partially open, on the basis of the flow rate of a fluid flowing through fluid passages, the drive device finely adjusts the position of the working shaft such that the flow rate is constant.

    Abstract: Provided herein is a pipe joint of a relatively small joint diameter for use under ultrahigh pressure conditions. The pipe joint includes first and second joint members having mutually communicating fluid passages; and a gasket interposed between abutting end surfaces of the first and second joint members. The first and second joint members have ring-shaped seal projections formed at the abutting end surfaces thereof. The pipe joint satisfies a coefficient F of 0.4 or less in the following formula (1). F=(D32−D12)/(D42−D22),   Formula (1): where D1 represents the inner diameter of the first and second joint members, D2 represents the inner diameter of the gasket, D3 represents the diameter of the seal projections, and D4 represents the outer diameter of the gasket.

    Abstract: Provided is a switching valve for use in an analyzer module for switching flow passages of fluids, in which the manufacturing cost is reduced and the life is increased. The valve element is provided with a lower contact portion that comes into close contact with a lower valve seat disposed at a valve body when a valve is closed, and with an upper contact portion that comes into close contact with an upper valve seat disposed at a counter plate when the valve is open. The counter plate has a first recess that is open downward and a second recess that is open toward the first recess and has a smaller horizontal cross-sectional area than that of the first recess, and the upper valve seat is press-fitted into the second recess.

    Abstract: Provided is a fluid controller in which reduction of the accuracy caused by the loosening of a screw portion and reduction of the durability caused by torsional stress are prevented. A stem vertical-movement-amount adjustment means 11 is provided with: a handle 41 which has a female screw 41b on an inner periphery thereof and which is rotatably supported by a casing 4; a movable body 42 in which a male screw 46b is provided on an outer periphery thereof and is screwed into the inner periphery of the handle 41; and a guide means 43 which prevents rotation of the movable body 42 relative to the casing 4 and which enables vertical movement of the movable body 42.

    Abstract: Provided are a fixing device for a lower-stage member which facilitates a leveling operation for making upper surfaces of lower-stage members coplanar, and can further enhance a vibration absorbing effect generated by an elastic member, and a fluid control device which includes the fixing device. A fixing device for a lower-stage member is configured such that respective lower-stage members (2) are fixed once and, thereafter, a desired lower-stage member (2) is moved upwardly against an elastic force (21) so as to finely adjust positions of upper surfaces of a plurality of lower-stage members (2). The elastic member (21) is formed of an annular body made of rubber or a synthetic resin. A cutout (21a, 21b) which imparts the elastic deformation by bending when a force in the vertical direction is applied to the elastic member (21) is formed on an upper portion and a lower portion of an inner peripheral surface of the elastic member (21).
