    摘要: A method of making printed circuit boards having a circuit pattern of conductive material on either or both faces and conductive pins leading from one face to the other. A conductive layer having a circuit pattern is placed in a mold, and the insulating plastic which forms the substrate of the board is molded to the layer. In one example, the pattern is in the form of indented portions in a continous layer of conductive material, and the excess conductive material is ground off after the board is molded. In another example, the conductive pattern is deposited on the face of a mold prior to molding the board. Conductive through holes are formed by coating pine in the mold, before molding, or conductive pins are inserted into the mold and remain in the finished board.

    摘要: A segmented core (1) for molding of an impeller (12), especially a pump impeller, includes at least three segments (2). All of the segments (2) have the same form and each segment (2) has connecting devices (3, 3′) for connecting the segment (2) with the adjacent segments (2). A method for molding an impeller (12) includes the steps of: providing a molding tool (14), providing a core (1) including at least three identical segments (2), which include the connection portions (3, 3′) for connecting the segment (2) with the adjacent segments (2); assembling of the core (1); placing the core (1) in the molding tool (14); molding the impeller (12), ejecting the core (1) and the impeller (12) out of the molding tool (14); and removing the core (1) from the impeller (12).

    摘要: The invention relates to a stamper in which an oxide film having a fine concave-convex structure made up of a plurality of fine pores having an aspect ratio represented by [the depth of the fine pores/the average interval between the fine pores] of 1 to 4 is formed on the surface of an aluminum base material which is made of aluminum having a content of Ti of 150 ppm to 500 ppm, a content of B or C of 1 ppm to 50 ppm and a purity of 99.9% or more. According to the invention, it is possible to provide a low-cost stamper in which the emergence of a pattern derived from the traces of crystal grains on the surface of the oxide film is suppressed, an article having a favorable appearance, which is manufactured using the above stamper, and a method for manufacturing the above.
