  • Publication number: 20210060636
    Abstract: A casting mold molding device, a casting mold quality evaluation device, and a casting mold quality evaluation method are capable of evaluating the quality (casting mold strength) of a molded green sand mold without measuring a green sand mold by using a casting mold strength gauge each time a green sand mold is molded in one frame. A green sand mold molding sensor that, during molding of a green sand mold, measures a pressure value applied to a joining section between green sand introduced into a casting mold molding space and a plate having a model attached thereto; and a casting mold quality evaluation device that evaluates the quality of a molded green sand mold from the pressure value.

  • Patent number: 9997314
    Abstract: The gas circuit breaker includes a sealed container filled with an arc-extinguishing gas, a pair of fixed arc electrodes arranged in the sealed container to be opposite to each other, a trigger electrode movably arranged between the fixed arc electrodes and generating an arc discharge according to movement, a pressurization chamber pressuring and increasing a pressure of the arc-extinguishing gas with pressurization means, and a pressure accumulation chamber in communication with the pressurization chamber and accumulating the pressurized arc-extinguishing gas. The trigger electrode switches the pressure accumulation chamber into a closed state or an open state. The pressure accumulation chamber is switched to the closed state in a first half of breaking of the electric current, and the pressure accumulation chamber is switched to the open state in a latter half of breaking of the electric current. The arc-extinguishing gas in the pressure accumulation chamber is guided to the arc discharge.
