  • Patent number: 7514034
    Abstract: A container capable of transferring molten metal from a factory that produces a molten metals such as molten aluminum alloys and so on to a factory that uses the molten metal while the molten metal being stored therein and supplying the molten metal to a use point using the pressure difference. The container comprises a frame 1a and a lining 2 having a passage for flowing the molten metal therein. The passage 34 is being provided at an inside of the frame and at least a part thereof is being surrounded by a member restricting a flow of a gas. The pipe 34 is, for example, made of a metal and inside thereof has a lining layer 34b formed with a refractory member. The pipe 34 may be structured with a ceramics. As such structure being adopted, even when a crack and the like is formed in the lining 2 of the container, the flow of a gas is shut off, resulting in stable supply of the molten metal.

  • Publication number: 20080255401
    Abstract: [OBJECT] To efficiently and assuredly making an object to be treated containing an agricultural chemical innoxious. [MEANS FOR SOLVING] The first pipe which alkali can be filled thereto is disposed to be capable of being inserted and pulled out to a first passage of the first processing chamber where agricultural chemicals are thermally decomposed. Accordingly, since a distance between the processing chamber and the alkali can be minimized, a zone where the thermally decomposed components of the agricultural chemicals are recomposed into agricultural chemicals or dioxins is almost eliminated. As a result, the contamination owing to the re-composition thereof can be prevented. In addition, since the first pipe can be readily exchanged, the throughput can be improved.

  • Patent number: 7381383
    Abstract: A treatment apparatus of the present invention includes a hermetic door 115b and a retort 115c as an interface for taking out a gaseous emission containing vaporized substances from an object to be treated which is being heated in a reduced pressure state in a second hermetic chamber 103 while maintaining conditions in the second hermetic chamber. When the retort 115c is inserted into a first opening 103b of the second hermetic chamber, the hermetic door 115b in an open state is shielded from the second hermetic chamber 103, whereby condensation of the gaseous emission at the hermetic door is prevented. Accordingly, condensates can be taken out while conditions such as temperature and pressure in the hermetic chamber are maintained without the treatment apparatus being stopped. The productivity of treatment is greatly improved by continuous operation of such a treatment apparatus.

  • Patent number: 7204954
    Abstract: A container does not need a member such as a stoke and the like that are exposed to the molten metal therein, thus the necessity to replace the parts such as the stoke and the like can be eliminated. In addition, there is no structure like the stoke in the container, the operability for the preheating is improved thus the preheating can be performed effectively. In addition, since a flow passage is formed inside the lining with high heat conductivity, inner heat of the container is easily conducted to the flow passage. Thus, the decrease in temperature of the molten metal that flows inside the flow passage can be suppressed to the utmost.
