摘要： PURPOSE:To allow a simple investment of a minimum limit and to efficiently, economically cool a surrounded space by surrounding a compartment to be cooled with a suitable wall member, forming a simple room opened at an upper part, supplying cold air into the room by an air conditioner, and overflowing the air from the upper part of the room. CONSTITUTION:A periphery of a place is suitably surrounded, for example, by a wall member such as a screen (a) to match a state of a jig site, a simple operating room S opened at its upper part is formed, a large quantity of cold air is continuously supplied thereto in a laminar state, and a cold air layer is formed in an operating space in the room S by utilizing a difference of densities of the cold air and warm air existing from the first in the room. That is, the cold air is always supplied at least to a position and height to become a behavior range of an operator to allow an operation in the layer. The cold air flows in a lower part in the room, but as it approaches a heat source, it is heated to be raised, it becomes together with the warm air disposed from the first in an upper part in the room to be released from the room. Thus, the cold air is always replaced, and eventually overflowed from the upper part of the room.

摘要： PROBLEM TO BE SOLVED: To enable a branching working with the necessary minimum excavation by checking the embedding position of an underground pipe by a surveying device using the radio wave, forming an excavated shaft toward the embedded pipe by an advancing device installed on the ground aside and above the embedded pipe, and connecting a branch pipe after excavated earth and sand in a muddy condition. SOLUTION: In connecting a supply pipe to an underground pipe such as one for water service in a branched manner an excavated shaft 5 is formed by driving an advancing head 4 of a supply pipe advancing device 3 provided on a private area side toward the drilling position of an opening part. An underground embedded object surveying device 6 using the radio wave is arranged on a road side, and the advancing direction and angle of the advancing head 4 are corrected while checking the position of a main-branch pipe 2. A protective tube 7 is press-fitted in the excavated shaft 5 from the ground, and high-pressure water is ejected from an ejection nozzle 8 to make earth and sand in a muddy condition. The earth and sand in the muddy condition are sucked and discharged through a discharge pipe 9, a branch hole is made in the main-branch pipe 2 using a scraping blade or the like, and a branch pipe is connected thereto through a pipe joint.

摘要： PURPOSE:To reduce an operator's load and to uniformly clean by evenly diffus ing the air from an air injection port to an entire operator while a working base for placing the operator is slowly rotated once or twice. CONSTITUTION:A stair tread 19 is rotated at a slow speed of the degree in which an operator placing on it does not feel giddy, and stopped when it is rotated once. If cleanness is required, it can be rotated with more time in the degree to be stopped when it is rotated twice. A blower is operated while the tread 19 is rotated, and clean air is diffused from an air injection port 15 to the operator on the tread 19. Since the operator is slowly rotated in a state that he is stopped on the tread 19, it is not necessary to alter a direction so that the air is diffused to the entire operator as prior art. Accordingly, clean injection air is uniformly brought into contact with the entire operator automatically in a state that he is stood on the tread 19 in a room, and dust adhered to operator's clothing, etc., can be removed.

摘要： PROBLEM TO BE SOLVED: To provide an overflow preventing valve which allows valve opening/closing operation from the outside even if pressure difference inside a pipe cannot lead to valve closing action due to tiny leakage on a secondary side.
SOLUTION: The overflow preventing valve cuts off passage of fluid by abutment of a valve element onto a valve seat when the downstream side pressure inside a pipe drops. During normal circulation, a spherical valve element 60 is biased by a coil spring 70 in a direction separating from the valve seat 43, and retained by a supporting member 52. When carrying out the maintenance due to occurrence of tiny leakage on a secondary side, the valve closing operation is manually executed. By using magnetic force generated by a ring-shaped external magnetic circuit member 8 slidably provided in the outside of the valve and an internal magnetic circuit member 6 provided to the inside of the spherical valve element 60, the spherical valve element 60 is seated on the valve seat 43 against the biasing force of the coil spring 70 to perform the valve closing operation.
