  • Publication number: 20070173691
    Abstract: A capsule-type medical device comprises a capsule main unit having functions for being inserted into the body cavity and performing medical acts such as taking images or the like. The capsule main unit comprises therein a magnet which is acted upon by external magnetism, and a spiral portion on the outer perimeter, so that rotating force acting upon the magnet is readily converted into a propelling force for propelling the capsule-type medical device. A flexible insertion portion which is long and small in diameter is provided to the capsule main unit to allow smooth progression through the body cavity, and the center of gravity of the device is placed upon the longitudinal center axis of the capsule main unit, thus facilitating smooth progression through the body cavity.

  • Publication number: 20070135680
    Abstract: A capsule-type endoscope comprising a capsule body, an image pickup element, illuminating elements, an image signal processing circuit, a memory, an image information transmitting circuit and an antenna for wireless transmission. The capsule body contains the pickup element, the illuminating elements, the processing circuit, the memory, transmitting circuit and the antenna. While the capsule body remains in a living body, the image pickup element takes images of an interior of the living body. The processing circuit processes the image, generating image information. The memory stores the information. The transmitting circuit reads the information and supplies it to the antenna. The antenna transmits the information by radio, from the living body.

  • Publication number: 20070108675
    Abstract: [OBJECT] To provide a container and a method of manufacturing the container that is capable of preventing unexpected rise of the pressure inside the container caused by the problem pertaining to the lining. [MEANS FOR SOLVING] Since the container 1 of the present invention has a structure such that the insulating wall 8 is being laid onto the inner side of the frame body 6 and the refractory storing bath 9 is detachably inserted from the opening 5 of the frame body 6 to be integrally provided with the container, the time consumed for drying can be shortened and the lining inside the container 1 can be prevented from containing fluid. Especially, a heat-insulating wall 8, a refractory storing bath 9 and the like are being made into dried components, drying step becomes unnecessary thus time consumed for manufacturing the container can be very short.

  • 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.

  • Publication number: 20070013114
    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.

  • Patent number: 7133138
    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.
