Abstract:
The present invention provides a radio wave transmission cover, which is provided in front of a radar device for vehicles, and a method of manufacturing the radio wave transmission cover. In the radio wave transmission cover, cover-side wall surfaces (50) are formed in a second cover layer (35) at positions adjacent to each other. Furthermore, substrate-side wall surfaces (60), which have shapes complementary to the cover-side wall surfaces (50), are formed in a substrate layer (4), which is provided on the rear surface of the second cover layer (35). The cover-side wall surfaces (50) and the corresponding substrate-side wall surfaces (60) are engaged to each other.
Abstract:
It includes an electroformed shell 6, which has a molding surface 60 and is formed by electroforming processing, a media flow path 2 for circulating a heat medium so as to perform temperature adjustment on the molding surface 60 formed in the electroformed shell 6, a backing member 71 with which the electroformed shell 6 is backed, and media conveying paths 74, respectively provided in an upstream-side end portion 21 and a downstream-side end portion 21, for flowing a heat medium into or out of the media flow path 2. A connecting jig 1 for connecting the media flow path 2 and the media conveying paths 74 is embedded in the electroformed shell 6. The connecting jig 1 includes a cavity portion formed therein, an opening hole having a cross-sectional shape which is substantially the same as the shape of a radially cross-section of the media flow path 2, and a connecting hole having a cross-sectional shape which is substantially the same as the shape of an outside diametrical cross-section of a pipe member 741 constituting each of the media conveying paths 74. The opening hole and the connecting hole are communicated with each other through the cavity portion.

Abstract:
A mold for integrally molding a cover and a pad on a steering wheel. The mold includes a first mold and a second mold relatively movable to the first mold. The first and second molds are separated from each other to place a metal core between the first and second molds. The first and second molds are then joined with each other to define a first cavity for molding the cover. Afterwards, the first and second molds are separated from each other to remove the metal core and the cover. A float core is located between the first and second molds. The float core cooperates with the first and second molds to define a second cavity for integrally molding the pad with the cover when the first and second molds are joined with each other. A pivoting mechanism pivots the float core to remove the steering wheel from the molds.
