    Abstract: A fluid control valve includes a multi-stage piston actuator unit with first piston and second pistons coaxially and slidably arranged therein and a valve unit provided with an inlet port for inflow of a control fluid and an outlet port for outflow of the control fluid. The first and second pistons are slidable in a sliding direction perpendicular to an imaginary line connecting the center of the inlet port and the center of the outlet port. The multi-stage piston actuator unit has a smaller thickness in a direction perpendicular to the imaginary line and perpendicular to the sliding direction than the thickness of the valve unit in the direction perpendicular to the imaginary line and perpendicular to the sliding direction. The first and second pistons have either an elliptic or oval cross-section taken perpendicular to the sliding direction, the cross-section having a long axis parallel to the imaginary line.

    Abstract: A fluid control valve for controlling high-temperature fluid includes: a valve body including a valve chamber communicating with first and second flow passages, and a valve seat provided in the valve chamber; a metal diaphragm that contacts with and separates from the valve seat; a stem that moves the metal diaphragm up and down; and an actuator that drives the stem. The first flow passage includes a first orifice having a diameter set to 50% or less of a diameter of the second flow passage. Alternatively, the second flow passage includes a second orifice having a diameter set to 50% or less of the diameter of the second flow passage. The diameter of the second flow passage is calculated by converting a cylindrical flow passage area defined between the valve seat and the metal diaphragm when separated from the valve seat into a diameter of a circular flow passage.

    Abstract: A blister sheet includes a container film including pockets receiving a content, and a cover film mounted to the container film to close the pockets. The container and the cover film are made of synthetic resins. The cover film is thinner than the container film. One pair of cuts formed for each pocket passes through the container and the cover film and extends to the pocket such that each pocket is placed between the cuts. The container and the cover film are broken from the one pair of cuts toward the pocket. A cutting slit or perforation is formed in the container film to allow for separation of the blister sheet into sheet pieces. The cutting slit or perforation is extended to intersect with the cut and a portion of the cutting slit or perforation that intersects with the cut passes through the container and the cover film.
