Abstract: Even in the case where there is an analysis mesh but no source 3D-CAD model remains, the present invention can easily modify a shape and efficiently create an analysis mesh. The present invention divides the analysis mesh into closed areas in a division step and stores the closed areas combined with attribute information on physical properties and meshes as a partial area in a partial area registration step, defines a total area in a total area registration step, changes the shape of a partial area desired to be changed in a partial area changing step, changes an arrangement in a partial area moving step, then constructs an analysis model by combining the partial areas and the total area in an area merging step and finally performs mesh division in a mesh division step.

Abstract: An apparatus uniformly heats a plurality of foods in addition to controlling the temperatures of the foods. The heat source has input means, a plurality of temperature detectors, comparison means, and control means. The apparatus detects temperatures of at least two foods, namely one near to the heat source and another far from the heat source by using the temperature detection means, and controls the output of heat from the heat source by comparing these two temperatures with the set-temperature. The apparatus can raise the temperature of foods of lower temperature while maintaining the foods of high temperature at the set-temperature. The plurality of foods can be thus uniformly heated.

Abstract: Data of physical property values of a material to be cooked and thermal conduction operation procedures are stored, and data of the material and heating data are input, so that a heating output of a particular part of the material may be calculated based on a distance between the particular part of the material and a predetermined reference point. A temperature rise value per unit time of the particular part of the material is obtained from the input data of the material and the heating output. A thermal conduction operation is carried out in accordance with the stored operation procedures with the use of the temperature rise value.

Abstract: The disclosure is directed to a mixed flow impeller with a low noise, to be used for a blower of an air conditioner or the like. The mixed flow impeller of the present invention is characterized in three points, i.e., thin thickness blade member increased in its thickness only at its leading edge, a plate-like triangular protrusion provided at an outer peripheral portion of the leading edge, and blade curvature line having its maximum curvature position deviated toward the trailing edge side through employment of a cubic curve. Since each of the above features may be caused to function independently, noise reduction is possible even if it is executed singly, but the maximum effect is available when the are effected in combination.
