摘要： A method for calculating the intensity of an electromagnetic field emitted from a device and a storage medium for storing a program of the method are disclosed. The method uses a moment method in which a mutual impedance between shell elements and a supplied voltage are assumed to be known quantities and the current flowing through the shell element is assumed to be an unknown quantity. The method comprises the steps of obtaining a plurality of shell elements including at least one triangular shell element by virtually dividing the device into a mesh, and setting an unknown quantity of a current directed from each side of the triangular shell element toward its apex only when a conductive wire is connected to the apex, setting an unknown quantity of a current directed from each side of the triangular element toward its apex when the side is common with a side of the other shell element, or setting an unknown quantity of a current parallel to a side of the triangular shell element when there is a shell element adjacent to the triangular shell element.

摘要： An electromagnetic field intensity computing apparatus for computing electromagnetic field intensity of an electric circuit device in a moment method obtains according to the electric current distribution an electric current of a ground layer and models a transmission line, ground layer, dielectric portion, etc. to be analyzed. When a plate to be analyzed is divided into a plurality of patches, the regularity in given structure data is automatically extracted to compute the mutual impedance among a portion of patches and apply the computation result to other portions. When elements to be analyzed meet the conditions that the electric length of the elements is short and the elements are distant from each other, the mutual impedance can be computed in an approximation obtained under various conditions. Furthermore, approximating a portion near a pigtail portion of a coaxial cable using a polygon allows a vertical electric current to be properly connected to each unit.

摘要： Body cavity fluids, such as ascitic fluid and pleural fluid, are concentrated and filtered to remove bacteria and cancer cells, and the filtered concentrate is returned to the patient intravenously. The concentration and filtration are performed batch-wise, with the concentration being done before the filtration. The apparatus for concentrating and filtering includes a first container for holding the body fluid, a second container for holding the final filtered concentrate, a filter, a concentrator, a pump and two branched tubes connected to the filter and the concentrator which tubes can be selectively closed for concentrating and filtering the body fluid. The fluid outlet of the first container is designed to help prevent precipitated fibrin from passing out of the container and blocking the concentrator or filter membranes.

摘要： In calculating an electromagnetic field intensity by a moment method, real and imaginary parts of a mutual impedance, mutual admittance, and mutual reaction between elements and of the elements themselves are approximated by a sum of terms each with a frequency raised to a power. The mutual impedances, etc. at a plurality of sample frequencies are calculated using known mathematical equations, and simultaneous equations obtained by substituting the sample frequencies and the mutual impedances at the respective sample frequencies into an approximate equation are solved to calculate approximation coefficients for the approximate equation. Using the thus obtained approximate equations, the mutual impedance, etc. at a designated frequency are calculated, and substituted into simultaneous equations describing a boundary condition for each element; by solving the simultaneous equations, the electric current, equivalent electric current, and equivalent magnetic current of each element are calculated, from which the electromagnetic field intensity is calculated.
