摘要： PURPOSE:To detect a leak of gas over a wide range with simple constitution by sucking gas sucked free end parts to the base end parts of detection pipes in common through the operation of a suction pump. CONSTITUTION:Free end parts 6a-8a of detection pipes 6-8 are open to plural detection spaces A-C. The base end parts 6b-8b of the detection pipes 6-8 are connected to the suction pump 9 is common. The suction pump 9 is operated to suck the gas from the free end parts 6a-8a to the base end parts 6b-8b of the detection pipes 6-8. The gas from the suction pump 9 is detected by one gas detecting element 14 of a gas detecting means 10. Thus, a gas leak is detected by one gas detecting element 14 over a wide range. Consequently, the gas leak is detected over the wide range through easy fitting operation, and the economical load is reduced and the maintainability is improved.

摘要： PURPOSE:To efficiently treat waste water contg. high-concn. suspended matter as well as ammonia and COD components by oxidizing the waste water in a liq. phase in the absence of catalyst and then oxidizing the water in a liq. phase in the presence of a catalyst deposited on a honeycomb structure. CONSTITUTION:When the waste water contg. suspended matter, ammonia, and >=2 kinds of COD components is wetly treated, the waste water is oxidized in a liq. phase in the absence of catalyst and in the presence of an oxygen-contg. gas. Then the water treated in the preceding stage is oxidized in a liq. phase in the presence of a catalyst body obtained by depositing iron, Co, Ni, Ru, Rh, Pd, Ir, platinum, copper, gold, W, and at least one kind among the compds. of the metals insoluble or difficultly soluble in water on a honeycomb structure and in the presence of an oxygen-contg. gas. Consequently, the waste water contg. high-concn. suspended matter as well as ammonia and COD components can be efficiently treated. Furthermore, the decolorization, deodorization, and sterilization of the waste can be simultaneously carried out.

摘要： PURPOSE:To simply, surely joint the pipes, by inserting the end of the pipe to be jointed into the pipe joint provided with the O-ring being set inside of the bulge ring, and then, by pressing this bulge ring from outside for indenting the pipe's outer surface inward. CONSTITUTION:The thin walled cylindrical socket 1 is prepared; this socket 1 is provided with the diameter contracted stepped part 1a at the middle, and also is provided with the outward bulging rings 1b, 1b, on both of the right and the left sides of the stepped part 1a, and besides, the O-ring 2 is set inside of each bulge ring 1b. Each opposite end of the pipes 3, 4, to be jointed together is inserted into the open mouths on both ends of this socket 1 so as to pass over the O-ring 2 until the pipes 3, 4, touch the diameter contracted stepped part 1a of the socket 1. Hereupon, each bulge ring 1b of the socket 1 is pressed inward by the suitable press die like as the press roller 5, etc.; hereby, the bulge ring 1b is forced to cause the plastic deformation so as to reduce the bulging height, and also, the wall of each pipe 3, 4, is circumferentially indented inward 3a, 4b, through the O-ring 2.
