摘要： PROBLEM TO BE SOLVED: To provide a pipe joint maintaining airtightness with respect to a vacuum vessel, and further performing a pressure test only by a joint without separately requiring a detachment preventing mechanism.
SOLUTION: This pipe joint connects the vacuum vessel to a pipe communicating with a vacuum device, and is provided with a cylindrical joint member 4a having one end connected to the connection part 1a of the vacuum vessel 1 and the other end connected to the pipe 3. The inside of the one end of the joint member 4a has a larger diameter than that of the connection part 1a. A first seal member 5 maintaining airtightness, a sleeve-like member 11, a second seal member 12 maintaining pressure to the connection part 1a, and a clearance member 6, are mounted in a clearance between the inside and the connection part 1a, and the clearance member 6 is fastened by a fastening member 7a from the outside of the one end of the joint member 4a. Thereby, the connection part 1a of the vacuum vessel is fixedly connected to the one end of the joint member 4a.

摘要： PROBLEM TO BE SOLVED: To detect a fluid pressure which is subjected to temperature compensation without actually measuring the temperature of a pressure detection element constituting a dual pressure sensor.SOLUTION: Two functions f1 and f2 respectively represent the temperature/pressure characteristics of two pressure detection elements 16A and 16B which are integrated in the state of contacting with each other. A temperature variable T and a pressure variable P are set to be common to the two functions f1 and f2. Taking that detection values S1 and S2 of the pressure detection elements 16A and 16B are the solutions of the functions f1 and f2, respectively, the pressure of the fluid is obtained by systematically solving the functions f1 and f2.
