    摘要: Molten metal is put under pressure of up to 10 atmospheres in a covered ladle and a gas soluble in the metal is bubbled through the melt. Some gas goes into solution, while the remainder rises in bubbles and brings inclusions suspended in the molten metal up to the surface. Then the pressure is lowered, after which gas comes out of the solution in fine bubbles which also bring impurity inclusions up to the surface. In another method molten steel is refined at pressures not exceeding atmospheric pressure in a covered ladle equipped for evacuation and equipped for bubbling gas through the molten steel bath. Bubbling followed by pressure reduction can then be performed to form two stages of cleaning. Heat may be added for compensating the cooling effect of gas expansion. Instead of a closed ladle, an open ladle may be used, into which there can be dipped a chamber fitted for evacuation and having two large tubes at opposite sides of the chamber extending downwards to orifices that may be lowered into the molten metal in the ladle. The melt is then drawn up into the chamber by atmospheric pressure as the chamber is evacuated. Then bubbling may be performed in one connecting tube by injection of gas from the bottom of the ladle, or at a mid-level of the tube, to produce circulation of the molten metal up into the chamber and down through the other tube.

    摘要: In an electron tube, an insulating tube protrudes inside an envelope. One end of the insulating tube is connected to the envelope. An avalanche photo diode (APD) is provided on the other end of the insulating tube. A ground voltage is applied to the envelope and a positive high voltage is applied to the APD. Photoelectrons which are emitted in response to an incident light on a photocathode are converged by an electrical field in the envelope and enter the APD. Thereafter, the incident photoelectrons are amplified and detected. Since a positive high voltage is not exposed to the envelope, the electron tube can easily be handled and is excellent in safety.

    摘要: A shock-proof device disposed in a buckle includes at least a latch member for engaging a tongue so as to latch the tongue; a release button for releasing the tongue from the latch member; and an inertia lever with a rotation shaft rotatably arranged for preventing the release button from moving at least in a release direction of the release button by abutting against the release button. The shock-proof device further includes torque-difference generating mechanism for generating a torque difference between a first torque and a second torque. The first torque is applied to the inertia lever when the inertial force is applied to the release button and the inertia lever in the release direction of the release button. The second torque is applied to the inertia lever when the inertial force is applied to the release button and the inertia lever in the non-release direction of the release button.

    摘要: A liquid scintillation counter 10 serving as an optical measurement apparatus includes: an HPD 24, a charge amplifier 26, a voltage amplifier 28, a comparator 30, a counter 32, a multi-channel analyzer 34, a display 38, and the like. The HPD 24 has a photocathode 24a and an APD 24b for outputting a signal that corresponds to the number of incident photons. The comparator 30 outputs a logic pulse signal, serving as a comparison result signal, only when the signal outputted from the HPD 24 and amplified by the charge amplifier 26 and voltage amplifier 28 is larger than a prescribed threshold value. This threshold value is set larger than an output signal that is outputted when a single photoelectron is emitted from the photocathode 24a and smaller than another output signal that is outputted when two or more photoelectrons are emitted.
