Abstract: PROBLEM TO BE SOLVED: To enable a change in the fixing position of a ball nut and facilitate a running test with a running test device set undisturbed at site by providing a running test device with a mechanical snubber following and moving functions under the conditions that equipment is supported. SOLUTION: Because the amount of displacing movement of a pipe is relatively small in normal operating conditions, when a fault due to a local wear of a ball shaft 7 against a ball nut 18 which is caused by a reciprocating running within a small area, the ball shaft 7 is rotated by a manual drive part and a running test device 20 after a ball nut fixing device 19 is removed. By this, the ball nut 18 can be moved to those areas other than the worn area of the ball shaft 7 in axial direction without changing the set length of a mechanical stopper 15 and, therefore, the ball nut 18 is re-fixed to the body 16 in the nearest mounting hole by the ball nut fixing device 19. Then a running test is performed again so as to confirm that the following mechanism of the ball nut 18 at the new position functions correctly.

Title: Froth-separation type purification of waste water by use of deep-layer aerating vessel
Inventor: KUSUNOKI HIDEO
IPC: C02F3/22
Filed: 1981-02-14
Abstract: PURPOSE: To reducen a load for treatment with active sludge, while removing pollutants at the same time, in a deep-layer aerating vessel comprising the descending and ascending currents of liquid to be purified and a depth of 20m or more, by agglutinating the pollutants to formed bubbles.  
     CONSTITUTION: Liquid A to be purified is introduced through the liquid-inflow pipe 10 of an opened air vessel 9, while compressed air C blown upwards into an ascending pipe 2 through a circulating air blowing pipe 4 to start the circulation of the liquid. Thereafter, compressed air C through a purifying air blowing pipe 3 is gradually increased in quantity and blown in downwards, so that a dissolved oxygen amount increases in proportion to a water head owing to the pressure of the deep layer. Consequently, the biochemical oxidizing efficiency of active sludge can be enhanced. When gaseous components dissolved in the opened air vessel 9 are separated, bubbles are formed by surface active substances contained in the water to be purified. The bubbles are introduced into a bubble removing chamber 5 and separated from the purified water.

Title: Remote monitoring and controlling device
Inventor: SUZUKI SHIYOUHEI
IPC: G08C25/00
Filed: 1982-02-12
Abstract: PURPOSE:To prevent fetching of fault information when transmission and reception are performed by consisting one information with plural words, by performing checking on the continuity of the word address of the plural words and monitoring on the receiving timer of the word to be received next. CONSTITUTION:A receiving word W4 (1)2 is set in B REG 8 and a data ready signal 32 is outputted. A word address signal 33 is outputted as W4 (1) address signal 34 and set in an FF15, and, at the same time, the signal 33 triggers one- shot OSs 13 and 14 and performs receiving time out detection of a W5 (2) word. On the other hand, receiving data 35 is set in 1 buffer 25 as W4 (1) data. When nothing can be received from a receiving word W5 (2)3, the OS 13 outputs a receiving time out signal 38 and clears the FF15. Even if the word W5 (2)3 is received and a W5 (2) address signal 36 is outputted, the FF16 is not set by the NOT of an FF output 37. The next receiving word W6 (3) is also processed in the same way. Therefore, an output set signal 42 to an output buffer 28 is not outputted, and no fault combination of words is outputted.

Title: Hot water circulating device
Inventor: MATSUMOTO MOTOKI
IPC: F24D3/10
Filed: 1990-01-30
Abstract: PURPOSE:To cushion hammer noise and to improve combustion efficiency through recovery of a heat from a water boiling can and a circulating flow passage by a method wherein an accumulator is provided in the middle of a circulating pipe. CONSTITUTION:Hot water fed to a radiator 3 by means of a steam pressure from a water boiling can 2 produces hot water mixed with steam when hot water in the water boiling can 2 is reduced. Since, during the starting of dry burning, the hot water almost produces steam, hot water and steam are alternately fed to a circulating pipe 4a and a radiator 3. As a result, the flow of hot water is suddenly changed to generate water hammer noise in the radiator 3. However, since an accumulator 5 is located in the middle of the circulating pipe 4a, the flow of hot water and steam is relaxed and smoothed at this part. Since steam is liquefied in the accumulator 5 and the flow of steam is relaxed, an amount of steam flowing to the radiator 3 is reduced, and mainly the flow of hot water is generated. Thus, the fluctuation in a pressure of the water boiling can 2 is not transmitted directly to the radiator 3, and water hammer noise is prevented from generation.

Title: Manufacture of oxide superconductive linear material
Inventor: TAKADA YOSHINORI
IPC: B28B1/00
Filed: 1988-01-29
Abstract: PURPOSE:To enable only Ag sheath to be effectively removed without exerting any harmful effect on an oxide superconductive tapelike or linear material having a Ag sheath by bringing the superconductive material into contact with molten metal capable of alloying with Ag. CONSTITUTION:An oxide superconductive linear material having a Ag sheath is brought into contact with molten metal capable of alloying with Ag thereby removing the Ag sheath. Namely, since the molten metal capable of alloying with Ag is brought into contact with the Ag sheath, only the Ag sheath is transferred into the molten metal in the form of the alloy, while the superconductive material existing inside the Ag sheath remains therein without suffering any corrosion or decomposition. Therefore, the Ag sheath can be easily removed, and as well any evil effect isn't exerted on the superconductive material.
