  • Publication number: 20060108720
    Abstract: When emergency shutdown operation becomes necessary while a gas used for applying pressure to the in of the container is being supplied from the receiver tank to the container, the lever is turned and the three-way valve is switched to the second mode. Then the first valve opening in the three-way valve is blocked and the supply of the gas used for applying pressure to an inside of the container from the receiver tank to the container is stopped. In addition, since the gas can flow between the second valve opening on the container side and the third valve opening opened to an atmosphere in the container is released to an atmosphere. In other words, in the present invention, the supply of the gas used for applying pressure to the in the container can be stopped and, in the same time, in the container is released to the atmosphere with a single action, namely, manually turning the lever provided close to the driving seat. Therefore, the safety level of the system is very high.

  • Patent number: 7029436
    Abstract: On the side at hand of an optical probe, a whole rotation transfer connector rotates while being supported by a ball bearing and a slide bearing and, therefore, rotation is transferred to a flexible shaft. The relative position between the flexible shaft and an optical sheath is changed in accordance with the amount of screwing of a sheath stopping member on the side at hand into an outer cylinder by an external thread portion and an internal thread portion. When the optical sheath is moved furthermore, the flexible shaft is elongated due to elastic deformation because the length of the flexible shaft is regulated by the interval between a locking part of a locking member at the tip and a shaft stopping member. A tip housing is made to contact with the locking member while tension is applied to the flexible shaft by the rear end surface in the direction of the side at hand.

  • Publication number: 20040109164
    Abstract: An optical imaging device includes a reference scanning unit offering a high signal-to-noise ratio and capable of scanning an object rapidly. An interference optical system can be realized inexpensively. In the optical imaging device, low coherent light passed through an optical coupler and another optical coupler, irradiated from an optical scanner probe, reflected from an observed point in a living tissue, returned to the optical coupler, propagated over a fourth SM optical fiber, and routed to another optical coupler shall be referred to as sample light. Light passed through an optical length variation optical system via the optical coupler and routed to the optical coupler shall be referred to as reference light. At this time, a difference between a delay time undergone by the sample light and a delay time undergone by the reference light is proportional to a difference between an optical length for the sample light and an optical length for the reference light.

  • Publication number: 20040070122
    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.
