A part of the primary molded body including the semiconductor chip is in the insertion hole.

Abstract: A part of the sealed surface of the thermosetting resin member is a non-roughened surface that is not subjected to a roughening treatment. The other part of the sealed surface is a roughened surface recessed from the non-roughened surface to form a step and more roughened than the non-roughened surface. The thermoplastic resin member includes an additive added thereto, and the additive contains a functional group. A functional group existing in the roughened surface and the functional group existing in the additive are chemically bonded together. The roughened surface has a closed-circular shape that is formed over an entire circumference of the sealed surface around an axis parallel to the first direction. The three or more roughened surfaces each having a closed-circular shape on the sealed surface are arranged along the first direction with the non-roughened surface interposed as a distance between each adjacent two of the roughened surfaces.

Abstract: A plurality of micro-recess portions, which are recess portions each having a depth in a micron order, are provided on a metal surface. In addition, a plurality of nano-asperities, each of which is a recess and a protrusion having a height or a depth in a submicron order or a nano order, are formed on the metal surface. The micro-recess portions have a lower number of the nano-asperities than in a flat portion, which is a section of the metal surface that is different from the section where the micro-recess portions are provided.

Abstract: In a method for producing a resin molded body, a thermosetting resin member is formed by heating a thermosetting resin material that is a raw material of the thermosetting resin member to complete a curing. A nascent surface having a functional group is formed on at least a part of a sealed surface of the thermosetting resin member by removing a surface layer that is an outermost layer of the sealed surface via irradiation of laser light to the sealed surface. The sealed surface of the thermosetting resin member is sealed with the thermoplastic resin member by injecting a thermoplastic resin material to the thermosetting resin member having the nascent surface, the functional group of the nascent surface being chemically bonded to the functional group of the additive. The thermosetting resin member has an absorption of the laser light at or above 10% per 1 ?m.

Abstract: A coaxial connector having excellent shielding performance. The coaxial connector 30 includes a coaxial cable 12, an outer conductor terminal 32 connected to a top end of the coaxial cable 12, an opening portion 34, stabilizers 36, and an engaging piece 44. The opening portion 34 locks a locking piece of a connector housing used to house the coaxial connector 30, the stabilizers 36 control an insertion orientation of the coaxial connector 30 into the housing, the engaging piece 44 engages with the locking piece, and they are provided on a peripheral surface at a main section of the outer conductor terminal 32. The opening portion 34 is closed by a main section of an outer conductor terminal of a counterpart coaxial connector when the connectors are mated. The engaging piece 44 functions as a guide plane when the stabilizers 36 are inserted into a slit of the housing.

Abstract: In a coaxial connector, when an inner conductor terminal connected to a signal conductor of a coaxial cable is inserted in and fixed to a dielectric member, which has been received in an outer conductor terminal in advance, by utilizing an upwardly-open space (opening portion) in the outer conductor terminal. A press-clamping portion serving as a connecting portion of the inner conductor terminal connected to the signal conductor is exposed in the opening portion. A matching convex wall is formed on an inner bottom surface of the opening portion to reduce the inner diameter of the opening portion toward the press-clamping portion, thereby matching the characteristic impedance of the connector also in the vicinity of the press-clamping portion. A shielding member closes the opening portion.

Abstract: A shielding connector is disclosed having a construction such that after an inner conductor terminal is press connected to a signal conductor of a shielded cable, it is pushed into a dielectric member previously placed in an outer conductor terminal by utilizing a space as an opening of the upper surface of the outer conductor terminal. A small diameter member is provided which electrically reduces the opening diameter of the terminal insertion hole in the vicinity of an inner conductor terminal press connection part, whereby the connector impedance matching is achieved also at the press connection part.
