摘要： PROBLEM TO BE SOLVED: To decrease the restriction on execution by eliminating a stopper part arranged between a pair of base members and arranging an opening to a side surface only on one side of a cabinet. SOLUTION: Instead of a stopper part 9 arranged between a pair of base members 5 (rail central part), an opening 7 is arranged to a side surface on the one side of the cabinet. The fixing method of each of the base members 5 is that the one edge on the opening 7 side is fixed by screws 10 to the edge part of a rail 6 and as the other edge of the base member 5 on the other side of the opening 7 cannot be reached by hands and the screws 10 cannot be used 7, it is pushed in along the rail 6 to be pushed into a stopper part 9 arranged to the edge part of the rail part 6 in advance and fixed, and each of the joining parts between a pair of base members 5 (central part of rails 6) is has the structure of wedge shape. Therefore, an air conditioner can be installed with the condition the space for extracting a blower unit 8 to either side of the left and the right of the air conditioner cannot be secured by the trade off with beams in the space of a ceiling plenum.

摘要： PROBLEM TO BE SOLVED: To minimize the leakage of refrigerant gas by performing the operation to recover the refrigerant by an outdoor unit in an air conditioner where the refrigerant such as fluorocarbon is used. SOLUTION: In a refrigeration cycle in which an outdoor unit A is connected to indoor units B, C through refrigerant pipes 13, 14, a refrigerant gas sensor is provided on each of the indoor units B, C. When the refrigerant gas leaks from the indoor units B, C, refrigerant recovery operation is performed in a state where a control valve 9 is closed and circulation of the refrigerant gas to the indoor units B, C is stopped. Refrigerant recovery time is determined by the capacity, etc., of the indoor units B, C, and the operation is completed by closing a control valve 10 after the refrigerant recovery operation is performed for a prescribed period of time. During the refrigerant recovery operation, the refrigerant bas returned from the indoor units B, C enters the indoor unit A from a stop valve 12, and stored in a refrigerant quantity adjuster 5 after the gas passes through an accumulator 6, a compressor 1, a four-way valve 2, an indoor heat exchanger 3, and an outdoor flow rate control valve 4.

摘要： PROBLEM TO BE SOLVED: To improve the reliability on the superconductive magnet of a linear motor train by varying the natural frequency of at least one inner vessel out of a plurality of inner vessels from those of other inner vessels, within one outer vessel. SOLUTION: For a superconductive magnet, 8-a, 8-b, 8-c, and 8-d different in rigidity are used as the load supports 8 to support and fix four pieces of inner vessels 2-a, 2-b, 2-c, and 2-d housing superconductive coils. Then, the natural frequencies of the inner vessels 2 come to severally different values, because the spring constants of the load supports 8 are all put to different values by putting the diameters of the cylinder parts 8C-a, 8C-b, 8C-d of the load supports 8 to severally support and fix the four pieces of inner vessels 2a-2d in severally different sizes. Further, the dispersion of the natural frequency is determined to be roughly 5%. As a result, it becomes to prevent the four pieces of inner vessels from resonating at the same time, and the reliability on the supperconductive magnet for a linear motor train can be improved by reducing heat generation.

摘要： PROBLEM TO BE SOLVED: To detect malfunction of a superconducting coil in an early stage and protect a superconducting coil by providing an element for magnetic flux detection inside an outer vessel of a superconducting magnet, judging the presence or absence of abnormality of an output voltage of the element and indicating malfunction based on the output signal thereof. SOLUTION: The inside of an outer vessel 3 of a superconductive magnet 1 is provided with search coils CA1 to CA4 as magnetic flux detection elements. Especially, the search coils CA1 to CA4 are installed at the side of a truck and a voltage signal induced in the search coils CA1 to CA4 is sent to a judgment device 10 through signal lines 31 to 34. The judgment device 10 judges which voltage of the search coils CA1 to CA4 is abnormal and sends an alarm signal indicating abnormality and a signal of a place which is out of order to alarm display device 15 through a signal line 37. The alarm display device 15 indicates detection of malfunction by a lamp, a buzzer, a CRT, etc., and displays the place of malfunction and the degree of the malfunction.
