  • Publication number: 20070165053
    Abstract: A transmission/reception element transmits an ultrasound wave to an ink liquid contained in an ink tank. At this time, a near sound field of the ultrasound wave is formed within a propagating member when it propagates the ultrasound wave transmitted from the transmission/reception element to the ink liquid. The transmission/reception element receives the ultrasound wave that is transmitted, reflected on the surface of the ink liquid, and comes back. An ink remaining amount calculating unit calculates the remaining amount of the ink liquid based on an elapsed time required from the transmission until the reception.

  • Patent number: 4051898
    Abstract: A static heat-and-moisture exchanger core comprises an enclosed shell structure having a plurality of heat-and-moisture transfer members statically disposed therein in superposed and spaced-apart relationship defining between each two adjacent members a static flow path. The shell structure has a box-shaped configuration having four side walls and contains numerous pairs of aligned openings in opposed side wall portions each pair opening into one of the flow paths. Each heat-and-moisture transfer member is composed of either Japanese paper or asbestos paper having a thickness of from 0.05 mm to 1.0 mm whereupon the laminations are heat conductive and moisture permeable to effect continuous and simultaneous heat and moisture exchange between two air streams flowing through alternate ones of the flow paths.
