Patent JP-H0531422-B2 (JP)
IPC: A61M60/882
Filed: 1985-03-28
Abstract: A double pump adapted for use as an artificial heart includes two ventricle-simulating chambers that are provided with respective inlets and outlets having valves incorporated therein and that are separated by a common partitioning wall structure. The wall structure has sections that are driven away from each other to reduce the volumes of respective ventricle chambers and expel liquid from the chambers through the outlets. The wall structure can also move laterally in response to differences in pressure between the chambers and hence change the volumetric ratio between them. This ensures a balanced action between the two halves of the heart- simulating pump during a systole phase and a diastole phase. The link mechanism is actuated by a cord through a motor, although only in one direction in the pressure phase, and hence the aforementioned changed volumes are readjusted primarily through the pressure exerted by the inflowing fluid. The pump may also include a variable volume atrium-simulating chamber communicating with the inlet to each ventricle-simulating chamber and having volume that is controlled in part by an externally acting gas pressure that varies in accordance with changes in the volumes of the ventricle chambers.

Abstract: The present invention relates to a system and a method of extraction liquid from a humid mass by compressing same. The system comprises a conduit of linear, circular or other shape through which the humid mass is displaced. The conduit is of rectangular cross-section, which cross-section can be constant or variable. Further, the conduit has perforated side walls along at least a liquid extraction working section of the conduit. The system further comprises elements which cause an axial pressure at the interior of the humid mass as well as a mechanism to displace at least one of the perforated side walls to convey the humid mass along the working section of the conduit in such a way as to generate between the interior surface of the perforated side walls and the humid mass a dynamic friction force which defines a pressure zone which is less than the axial pressure created by the pressure creating elements. This difference in pressure causes the liquid in the humid mass to flow out of the mass in a direction substantially transverse to the displacement direction of the humid mass and out through the perforated side walls of the conduit.

Such a fluid storage lower layer of the absorbent core is placed underneath an upper, preferably larger, fluid acquisition/distribution layer containing little or no hydrogel. This lower fluid storage layer is positioned in such a manner that at least about 75% of the hydrogel in the lower layer is found in the front two-thirds of the absorbent article and such that at least about 55% of the hydrogel in the lower layer is found in the front half of the absorbent article. Absorbent articles of this type make especially effective and efficient use of the hydrogel material and may also provide a diaper rash control benefit. Absorbent cores of the type utilized in such articles are also disclosed.

Abstract: A single spring presses a moving printhead against a pivotable platen while simultaneously engaging a sliding carrier upon two parallel cross slides. The printhead is mounted on an arm hinged to the carrier. The axis of the hinge is parallel to the line of motion of the carrier along the cross slides. The spring pushes the arm away from the carrier and produces a moment about the hinge which keeps the carrier engaged with the cross slides. The platen pivots to remain completely parallel to the surface of the printhead as the carrier moves along the cross slides.

CONSTITUTION:A honeycomb cell structure is formed into a sandwich structure by laminating thin plates comprising aluminum each having a thickness of 1-2mm. to both surfaces thereof and the heat of the surface of a head base plate is absorbed with the said aluminum thin plate layers to enhance heat dissipating effect due to the honeycomb cell. The honeycomb cell structure is formed on honeycomb cells 10, a head base plate 11, a heat generating resistor 12, a head base plate support plate 13, a cell layer 10a and a display part 10b. The honeycomb cell forming material desirably comprises a light metal foil such as an aluminum foil excellent in heat conductivity and having a thickness of 20-50mum and the cell shape may be selected in the size thereof on the basis of heat dissipating capacity but it is adequate to use a hexagonal cell of which one side is 1-3mm.. In addition, by constituting the honeycomb cell shape so that cell density becomes radially coarse from the dense central part in order to deal with the thermal distortion of the base palte, the heat dissipating area of the heat dissipating plate becomes wide at the central part thereof and, because cell density is high at the central part, the strength of the heat dissipating plate is enhanced.
