Abstract: [Task] To improve the cooling efficiency of a heat sink without increasing the size of the heat sink. [Means for solution] A heat sink 1 includes a plurality of coolant passage 2, 3, and a connecting passage 4 connecting the coolant passages 2, 3 nonlinearly. A height of a fluid passage of the connecting passage 4 on an inflow side to which the coolant flows in is made greater than a height of the coolant passage 2 connected with the fluid passage on the inflow side. On the other hand, the height of the fluid passage of the connecting passage 4 is decreased to an end portion of the connecting passage 4 on an outflow side from which a cooling water flows out. In increasing the height of the fluid passage of the connecting passage 4 on the inflow side to which the cooling water flows in, gradually, the height of the connecting passage 4 is increased so as to equalize the height of a widthwise direction of the fluid passage of the coolant passage 2.

An open end 3K of the radiation electrode 3 and a capacitive coupling end 4Y of the feed electrode 4 are formed on a surface of the same insulator layer of the dielectric substrate 2.

The floating electrode 5 is arranged to commonly face both the open end 3K of the radiation electrode 3 and the capacitive coupling end 4Y of the feed electrode 4 in the stacking direction of the insulator layers 7a to 7e.

Abstract: A system for supporting an overall product design process including design of machining processes. Machined portion models, each including solid shape and/or machining attribute data of a machined portion defined in the machined portion model, are prepared on a machining operation basis and stored in a library. The library is provided as a standard machined portion library. A design engineer designates the machined portion models to be applied to a product model, which is a solid model displayed on a CAD apparatus, and specifies application positions and application directions thereof. Based on this designation, the CAD apparatus finds a product model representing a product shape formed after the machining operations, each corresponding to the selected machined portion models are completed. By sequentially applying the machined portion models to a blank material model of a blank material of the product, the product model is generated.

Unit process model information concerning a unit process model which can be machined using a single tool is used to define a product model. The unit process model information includes information concerning the shape and machining property of a machined portion. A combination of the unit process model information and disposition information for a machined portion constitutes machining step information indicating a single machining operation. When machining information formed by providing the machining step information according to an actual machining sequence is combined with a blank material model which is the subject of the machining, a product model including the final product shape and machining information can be obtained.
