Patent KR-920000435-B1 (KR)
Title: A double pump adapted for use as an artificial heart
Inventor: LUNDBACK STIG
IPC: A61M60/882
Filed: 1985-03-29
Granted: 1992-01-14
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.

Granted: 1995-08-16
Abstract: A process for making a shaped member from sheet metal pieces (37,38) of different thicknesses. In the process flat sheet metal pieces (37,38) are butt welded at their cut edges by laser beam welding. Then the unit, welded together from a number of sheet metal pieces (37,38) of different thickness, are converted into a shaped member by pressing or deep drawing. Since the material of sheet metal pieces (37,38) is not much affected by laser beam welding and the laser-beam-welded joint (39) does not expand much, the joint (39) has no adverse effect on shaping, nor is any anti-corrosion protection, for example, of zinc lost during laser beam welding.

Granted: 1995-08-03
Abstract: The magnetic composition of dielectric ceramics for temperature compensation comprises 70 mol.% titanium dioxide, 20 mol.% barium carbonate, 9.5mol.% neodymium oxide, 0.5 mol.% cerium oxide and 0<SiO2=<1 wt.% silicon dioxide. The dielectric ceramics is manufactured by sintering the molded body with the composition at 1,240-1,300 deg.C. The dielectric ceramics body with the composition has properties of high permittivity, low temperature coefficient, good quality coefficient in high frequency, high insulation resistance and low sintering temperature.
