Title: Slow cooling method for bloom or billet
Inventor: FUKUDA KAZUYUKI
IPC: C21D9/00
Filed: 1980-04-18
Abstract: PURPOSE:To shorten the time required for slow cooling and enhance the activity rate of a slow cooling furnace by estimating the slow cooling time on he basis of the concentration of hydrogen in the bloom or billet before slow cooling and the change of furnace temperature with time, when slowly cooling the bloom or billet. CONSTITUTION:The initial hydrogen concentration of the bloom or billet, that is, the amount of hydrogen in the steel before slow cooling, is determined by analysis when the steel is molten. Then, the bloom or billet is placed in the slow cooling furnace and the furnace temperature is measured with the progress of time so as to estimate a curve of furnace temperature against time. On the other hand, in order to estimate the concentration of hydrogen in the steel, the diffusion coefficient of hydrogen in the steel is obtained on the assumption that the temperature of the bloom or billet is equal to the furnace temperature, and the amount of residual hydrogen at a given time is obtained by using the initial hydrogen concentration which is measured in advance. Based on the value thus obtained and a reference value of residual hydrogen concentration which is predetermined for each material, the slow cooling time for the bloom or billet is estimated and the latter is taken out from the furnace in accordance with the estimated time.

Filed: 1989-03-04
Abstract: PURPOSE:To directly and quantitatively measure free hemoglobin with a high sensitivity by using the solid phase human haptoglobin formed by conjugating human haptoglobin with a solid phase and the oxygen labeled antibody formed by conjugating oxygen with an anti-human haptoglobin antibody. CONSTITUTION:A free hemoglobin-contg. specimen which is adjusted in concn. with a suitable buffer soln. at need is brought into reaction with the solid phase human haptoglobin. The supernatant is thereafter removed, by which the free hemoglobin conjugated specifically with the solid phase human haptoglobin is made to remain on the solid phase. The oxygen labeled antibody is then added thereto, by which the oxygen labeled antibody is conjugated with the free hemoglobin remaining on the solid phase. After the excess oxygen labeled antibody failing to be conjugated is removed, the oxygen activity is measured. On the other hand, the relation between the free hemoglobin and the oxygen activity is formed by making the similar operation on the sample solution of the standard free hemoglobin diluted to 3-5 stages. The free hemoglobin quantity in the specimen is determined by contrasting the resulted oxygen activity and a calibration curve.

Abstract: PURPOSE:To enhance the electromigration-resistance of a multilayer film which is constituted of the following: a high-melting-point metal film formed by a chemical vapor growth method; and an aluminum alloy film formed by a sputtering method. CONSTITUTION:A high-melting-point metal compound film, a high-melting-point metal nitride film or a high-melting-point metal oxide film as a buffer layer 8 exists between a tungsten film 7 and an aluminum alloy film 9. Thereby, even when the unevenesss of the surface of the tungsten film 7 is large, crystal particles in the aluminum alloy film 9 do not become small and its electromigration-resistance which should be possesed by an interconnection is enhanced. The reliability of their contact is guaranteed by the tungsten film 7 formed by a chemical vapor growth method, and, when a multilayer film is formed by the tungsten film 7 and the aluminum alloy film 9, its interconnection resistance can be lowered. In addition, since the concentration of copper contained in the aluminum alloy film 9 can be lowered, the aluminum alloy film is not corroded, and its practical effect is large.

Abstract: PROBLEM TO BE SOLVED: To provide a low-cost refrigerating device and a refrigerant leakage detecting method to detect leakage of a refrigerant without using a refrigerant sensor and to stably detect leakage of a refrigerant for a long period. SOLUTION: In this air-conditioner, a liquid refrigerant is stored in a refrigerant circuit and the temperature of a liquid refrigerant is detected by a temperature sensor 11 mounted on the lower part of the header of a heat-exchanger 1 on the indoor machine side. Further, a refrigerant leakage deciding part 15 decides that the refrigerant rapidly leaks when the refrigerant temperature detected by the temperature sensor 11 is lowered at a speed exceeding a given value when a compressor 6 is stopped. This air-conditioner detects rapid leakage of the refrigerant by detecting reduction of temperature, occurring when the liquid refrigerant rapidly leaks, by the temperature sensor 11. Thus, leakage of the refrigerant is detected without using a refrigerant sensor like a conventional type and leakage of a refrigerant is stably detected for a long period.

Inventor: ARAKI TSUTOMU
IPC: H01J29/48
Filed: 1982-03-30
Abstract: PURPOSE:To obtain good resolution over the whole region of a target surface by applying an auxiliary electrode plate with a small aperture for limiting the electron beam diameter to the end plate section on the G2 electrode side of a G3 electrode. CONSTITUTION:When each voltage of 300V and 800V is applied to a G2 electrode 9 and a G3 electrode 10, a focusing type electron lens is generated between both electrodes and an electron beam emitted from a cathode 1 advances in a convergence path. The current density passing through a small aperture 11a for limiting the beam diameter is increased comparatively and the angle of divergence is reduced comparatively. This indicates that the operating voltage of a G1 electrode and a crossover point are deviated to the negative side and the cathode side, respectively. That is, the current density and cathode load in the crossover point are reduced and the angle of beam divergence becomes narrow. As a result, high resolution can be obtained in the peripheral section of a target electrode surface through the captioned pickup tube is of a UPF type.
