Title: Vibration monitor
Inventor: YAMADA MITSUHIRO
IPC: G01M99/00
Filed: 1981-09-22
Abstract: PURPOSE:To detect an abnormal vibration level and a defective detecting system based upon the set comparison value of computer and amplification factor, by a method wherein the comparison value and amplification factor of a signal applied from the comparison value are controlled. CONSTITUTION:An amplifier 7 amplifies an output of a vibration detector 1 to the desired level. A variable amplification factor amplifier 8, which is designed to be able to pre-set an amplification factor according to a command from a computer 10, further amplifies the output of the amplifier 7 to the required level. A comparator 9 compares this signal with the reference comparison value which  is given from the computer 10 depending on the case, and applies the result to the computer 10. The computer 10, at first, sets the amplification factor of the amplifier 8, then, makes the comparison value of the comparator 9 vary, and determines the comparison value at the time when the output is applied from the comparator as the level of vibration. The computer 10 gives an alarm for the abnormal vibration when the vibration level exceeds the set abnormal level, and gives an alarm for the defective detecting system when the comparison value is less than the normal level at the descretion that there occure some troubles in the vibration detector 1, amplifiers or connecting cables.

Abstract: PURPOSE:To prevent oxidation on the surface of molten steel and precipitated crystals from occuring, by placing low m.p. molten slag on the molten steel surface and heating the same with an electrode at the time of solidifying the molten steel poured into a mold while blowing an inert gas from the lower part of the mold. CONSTITUTION:At the time of casting molten steel 2 in a mold 4, an inert gas such as Ar is blown in the form of air bubbles 18 from a porous slag 8 and is allowed to ascend in the molten metal, whereby the molten metal is stirred. At the same time, a molten slag layer 14 of a m.p. lower than that of the molten steel to be cast, less FeO content and superior fluidity is formed within the head flask 12 on the mold 4. An electrode 16 is inserted into this molten slag layer 14, and the power is supplied across the same and a molding board 6 or the mold 4, whereby the molten slag 14 is heated. The nonmetallic inclusions floating together with the inert gas 18 are captured by the molten slag 14, and the molten steel 2 is shut off from air by the molten slag layer 14, whereby oxidation is prevented and the formation of precipitated crystals is obviated. In this way, the defectless cast ingot which is small in contents of nonmetallic inclusions and H2 and has fine structure may be produced.

Filed: 1996-06-12
Abstract: PROBLEM TO BE SOLVED: To secure the flow rate of an air flow to a housing pipe even when wastes (hereinafter called 'waste') are housed in a very small number of the pipes by dividing the lower space in a pit into front and rear sections and providing a partition plate which can be moved in the forward-backward direction of the pit between the front and rear sections. SOLUTION: A partition plate 21 which is moved by means of a driving device 24 and divides a space below a lower plenum forming plate 16 into front and rear sections in the forward-backward direction of a pit 4 is provided on a guide rail 19 laid on the floor 18 of the pit 4. When wastes 2 are only housed in an extremely small number of pipes 3, the wastes 2 are housed in the pipes in order front the pipe 3 nearest to the front-side air inlet port 7 of the pit 4 and the partition plate 16 is moved to a position immediately below the row of the pipes 3 housing the wastes 2 and other rows of pipes.  As radioactive materials decay, the air temperature in an air flow passage 12 is raised by the decay heat and an air flow is generated to the outside of the main body 1 of an exothermic waste storing facility through an air outlet port 8 and, at the same time, the air flow from the outside of the body 1 flows in the passage 12 through the inlet port 7. Since the flow passage of the air flow to the rear end side of the pit 4 is intercepted by the partition plate 21, most of the air flow from the outside advances to the passage 12 annexed to the pipes 3.
