Abstract
A joint includes a first block, a second block, and a single pipe section connecting the first block and the second block. The first block, the second block, and the single pipe have a first gas passage and a second gas passage inside therein. The first gas passage is formed so that a first port which opens at an outer surface of the first block, the single pipe section, and a second port which opens at an outer surface of the second block communicate with each other. The second gas passage is formed so that a third port and a fourth port which open at the outer surface of the second block communicate with each other. The second port is disposed between the third port and the fourth port.

A joint comprising:
- a first block;
- a second block;
- and
- a single pipe section connecting the first block and the second block, wherein
- the first block, the second block, and the single pipe has a first gas passage and a second gas passage inside therein,
- the first gas passage is formed so that a first port which opens at an outer surface of the first block, the single pipe section, and a second port which opens at an outer surface of the second block communicate with each other,
- the second gas passage is formed so that a third port and a fourth port which open at the outer surface of the second block communicate with each other,
- the second port is disposed between the third port and the fourth port,
- the first gas passage includes a first passage formed on the first block and a second passage formed on the second block,
- the first passage includes the first port and an another port, the another port of the first passage opening at an another outer surface of the first block orthogonal to the outer surface at which the first port opens, the another port of the first passage being connected to the single pipe,
- the second passage includes the second port and an another port, the another port of the second passage opening at an another outer surface of the second block orthogonal to the outer surface at which the second port opens, the another port of the second passage being connected to the single pipe, and
- the outer surface of the first block and the outer surface of the second block face a same side, and the first port and the second port open on a same side.
A fluid control device comprising:
- a plurality of gas lines, each of the gas lines including a plurality of fluid control apparatuses and joints on which the fluid control apparatuses are installed, wherein
- the joint including:
- a first block;
- a second block;
- and
- a single pipe section connecting the first block and the second block, wherein
- the joint has a first gas passage and a second gas passage inside the joint,
- the first gas passage is formed so that a first port which opens at an outer surface of the first block, the single pipe section, and a second port which opens at an outer surface of the second block communicate with each other,
- the second gas passage is formed so that a third port and a fourth port which open at the outer surface of the second block communicate with each other,
- the second port is disposed between the third port and the fourth port,
- the first gas passage includes a first passage formed on the first block and a second passage formed on the second block,
- the first passage includes the first port and an another port, the another port of the first passage opening at an another outer surface of the first block orthogonal to the outer surface at which the first port opens, the another port of the first passage being connected to the single pipe,
- the second passage includes the second port and an another port, the another port of the second passage opening at an another outer surface of the second block orthogonal to the outer surface at which the second port opens, the another port of the second passage being connected to the single pipe, and
- the outer surface of the first block and the outer surface of the second block face a same side, and the first port and the second port open on a same side.
