Title: Calculating device and storage medium
Inventor: SUDO TOMOHIRO
IPC: G06F15/02
Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To provide a calculating device which can calculate/display the solution of an equation as an expression shown by a character variable by inputting the character variable or the expression containing the character variable to the coefficient of the equation and to provide a storage medium. SOLUTION: A CPU 11 in a computer 1 executes an equation processing. When an equation is inputted from an input part 3, a CPU 2 detects a variable contained in the inputted equation and displays it on a display part 4. When the values of the respective variables constituting the equation are inputted, the CPU 2 discriminates whether the character variable or the expression using the character variable exists in any value of the inputted variables. When the character variable or the expression using the character variable exists, the CPU 2 substitutes the values of the respective variables in the inputted equation for the variables and calculates a solution by using the expression processing. When the calculated solution is the expression containing the character variable, the CPU 2 displays the expression on the prescribed position of the display part 4 as the solution.

IPC: A01N59/00
Filed: 1988-11-25
Abstract: PURPOSE:To improve the mud scrubbing effect and dust removing effect of shoes and prevent the scattering of the removed dust by using a mat formed of a pile fabric woven using a modified yarn formed by spinning and drawing a polymer as a chemical fiber spinning raw material formed by mixing ceramic powders. CONSTITUTION:A doormat comprises a mat part 2 formed of a pile fabric made by mixing ceramic powders 3 with a polymer as a chemical fiber spinning raw material, injecting the resulting polymer through a modifying nozzle to spin a modified yarn and waving the modified yarn 4 as a pile yarn, and a mat base plate 5 to which the mat part 2 is installed. The pile yarn 4 consists of fibers of forms free from circular form, and the friction of the group of the fibers with shoes is extremely high, so that the mud and dust adhered to the shoes can be removed efficiently. As the removed dusts are perfectly caught in the modified yarn (pile yarn) 4 and never easily scattered, the mat is extremely hygienic. Further, as infrared rays are regularly emitted from the ceramic powders 3, the refrigeration of the mat is retarded in winter, and its thawing is easy.
