IPC: C21C7/10
Filed: 1989-01-19
Abstract: PURPOSE:To safely and quickly execute exchange of degassing vessel by removing a lower vessel, which completes the use at hot state, after melting and removing solidified metal stuck to inner wall in a vessel by blowing oxygen and exchanging into a new lower vessel. CONSTITUTION:In the RH degassing vessel, after completing the treatment, the whole of molten steel is returned back into a ladle. After that, immediately electrodes are removed to insert the pipes 30 in holes 20. A cuter is removed from a hole 18 to insert the pipe 30. Gas containing the oxygen as main component is supplied in each pipe 30 and blown to the stuck metal 24 to melt the metal 24 and the melted metal is discharged to out of the vessel through the submerged tubes 12, 14 little by little.

Filed: 1997-01-23
Abstract: PROBLEM TO BE SOLVED: To achieve a reduction in cost by reducing the length of piping as much as possible even in an air conditioning system using a plurality of outdoor units. SOLUTION: In this air conditioning system, an outdoor unit 1 and a room unit 2 are arranged in a building so as to position the outdoor unit 1 above the room unit 2 while the both are interlinked by a refrigerant piping to circulate a refrigerant by a difference in specific gravity between a refrigerant liquid mainly liquefied by the outdoor unit 1 and a refrigerant gas vaporized by the room unit 2. In this system, a plurality of outdoor units 1 are arranged in the building at positions above the room unit 2 and are connected in parallel to a main refrigerant liquid piping 3 and a refrigerant gas piping 4 while a plurality of room units 2 are connected in parallel to the refrigerant liquid piping 3 and the refrigerant gas piping 4. Thus, even when a plurality of outdoor units 1 are arranged, the main refrigerant liquid piping 3 and the refrigerant gas piping 4 are used in common to circulate the refrigerant. This enables shortening of the piping as much as possible to simplify application work thereby achieving a reduction of cost.

Title: Hydraulic pressure sensing type water sampling device
Inventor: OI YUKIO
IPC: G01N1/12
Filed: 1989-01-19
Abstract: PURPOSE:To obtain the device which suits to the sampling of underground water at large depth by utilizing the displacement of a piston supported by a spring with hydraulic pressure and opening and closing a water sampling container. CONSTITUTION:The hydraulic pressure applied to the piston 12 rises as the water sampling device is lowered in underground water. Consequently, the piston 12 is intruded into a spring case 18 against the force of the spring 16. When the water sampling device reaches specific water sampling depth, the lower ends of an air discharge groove 30 and a water sampling groove 32 protrude from the reverse surfaces of an upper plug 21 and a lower plug 22 by the downward movement of the piston 12 at this time. Then, the air in the water sampling container 10 is discharged through the air discharge groove 30 and peripheral underground water enters the water sampling container 10 through a water sampling nozzle 38 and the water sampling groove 32 almost at the same time. Then, the hydraulic pressure becomes low as the device is lifted, so the piston 12 is elevated gradually and the lower ends of the air discharge groove 30 and water sampling groove 32 enter the upper plug 21 and lower plug 22. Consequently, the water sampling container 10 is sealed automatically.

Title: Ultrasonic distance measuring apparatus
Inventor: TAKESUTE TAKAAKI
IPC: G01S7/52
Filed: 1992-01-24
Abstract: PURPOSE:To enable the measuring of distance between a plurality of ultrasonic vibrators and an object to be measured by arranging the plurality of ultrasonic vibrators, the one on the end side thereof used for transmission and the others for receiving. CONSTITUTION:An ultrasonic wave 26 transmitted from an ultrasonic vibrator 14 for transmission is reflected on an object 28 to be measured at the position as indicated with a solid line of a probe 10, and then is returned through almost the same path 26 as that in the transmission. At this point, the probe 10 already moves to the position of 10A as indicated by the broken line, and hence the vibrator 14 is located at the position of 14A as indicated with a broken line. As the ultrasonic vibrators 16 and 18 for receiving are also moved to the positions of 16A and 18A, the two vibrators 16 and 18 are not allowed to receive the reflected wave. But as ultrasonic vibrators 20 for receiving are moved to the position of the vibrator 14 where the vibrator 14 is located before moved, the reflected wave is received with the vibrator 20. This enables the measuring of the distance between the object 28 to be measured and the ultrasonic vibrator based on the reflected wave received.
