  • Patent number: 6655542
    Abstract: An ink tank producing a stable negative pressure regardless of material used is provided. In the ink tank, inner and outer walls include a bonding region having a bonding force distribution. With this arrangement, since the inner wall separates from the outer wall as ink in the ink tank is being guided out, the area of a non-bonding region increases.

  • Patent number: 6641763
    Abstract: A forming method for a fiber aggregate in which fibers are heated to be welded with each other includes a heating step of applying upward heated air to a bottom of a block of the fibers to pass the heated air therethrough and to cause the block of fibers to float, wherein at least parts of fibers are melted while the block of fibers float, and a compression step of compressing substantially in a vertical direction the heated block of fibers into a desired height. The compressed block of fibers is cooled to solidify melted portions of the fibers at portions where the fibers intersect with each other.

  • Patent number: 6543886
    Abstract: There is disclosed a liquid supply method in which a bubble is prevented from being retained or accumulated in a communication part. An upper wall surface of a joint pipe for connecting a negative pressure control chamber container to an ink container is inclined upward to the ink container from the negative pressure control chamber container. Since the upper wall surface of the joint pipe is inclined, the bubble flows into the ink container without being retained or accumulated on the upper wall surface of the joint pipe during gas-liquid exchange.
