摘要： A vehicle chassis includes a pair of rear side members disposed on a rear floor of a vehicle so as to extend in a longitudinal direction of the vehicle while being spaced apart in a transverse direction of the vehicle. The pair of rear side members is manufactured in a casting process A cross member is configured to extend in the transverse direction of the vehicle and is manufactured in an extrusion process. The cross member is inserted into a mold when the rear side members are cast such that both ends of the cross member are connected to the rear side members disposed on both sides, respectively.

摘要： A method of manufacturing a golf club head enables increased moment-of-inertia and improved durability. The golf club head's crown portion has a first region having a first thickness and multiple second regions having a second thickness that is smaller than the first thickness. The second regions are distributed in a radiating fashion so as to extend from an origin toward a peripheral portion of the crown portion excluding the face side, the origin being located within 15 mm of the center of gravity of the golf club head in the toe-heel direction and also being located in the vicinity of the face side in the face-back direction in a plan view.

摘要： A casting system includes a casting for an automobile vehicle having an interior section. Multiple central portions are individually positioned in one of multiple areas of the interior section completely encapsulated by a metal of the casting. An insert member is positioned in individual ones of the multiple central portions, the insert member having a higher melting point than a melting point of a metal of the casting the insert member displaces.

摘要： A method for manufacturing a mold element using a manufacturing device comprising a die and a counter-mold defining a molding cavity in the closed position, comprises: opening the manufacturing device; placing at least one insert 22, produced by laser sintering, against a molding surface of the die; mounting at least one wedge 28 on the die so as to bear against said insert in order to immobilize it relative to said molding surface; closing the manufacturing device, the counter-mold pressing onto said wedge in order to keep said insert pressed against said molding surface; injecting aluminium into the molding cavity of the manufacturing device; opening the manufacturing device; and extracting from the manufacturing device the mold element provided with a molding face formed by at least part of said insert and by the aluminum.

摘要： A method for producing a vibration-damping structure combination for damping vibrations for movable masses, having a first structure and a further structure, the further structure movable within a stop surface defined by a first structure surface of the first structure. The method includes a) providing the first structure, having the first structure surface and which defines a coating surface of a coating at least in some sections; b) coating the first structure surface of the first structure with the coating, the coating surface of the coating being applied such that a cavity is formed; c) filling the cavity with the filler; d) curing the filler until the further structure having a further structure surface is formed, which lies against the coating surface; and e) removing the coating, the further structure thus being movable relative to the first structure within the stop surface defined by the first structure surface.

摘要： A rotor of a rotary dynamoelectric machine incudes a magnetically conductive body, having substantially axially running slots distributed around the circumference. A squirrel cage includes electrical conductors which are arranged in the slots. The electrical conductors are electrically contacted at the two end faces of the rotor by short-circuit rings. The magnetically conductive body includes a base body and at least two further additional bodies, which axially adjoin the base body. A first one of the at least two additional bodies directly axially adjoins the end face of the base body, and a second one of the at least two additional bodies and optionally any further additional body axially adjoin the first additional body. The slots have radially exposed slot portions in the axial end regions of the rotor such that the conductors can be moved radially outward.

摘要： A transaction device includes a metal layer with one or more discontinuities in the metal layer. Each discontinuity comprises a gap in the metal layer extending from the front surface to the back surface, including at least one discontinuity that defines a path from the device periphery to the opening. A transponder chip module is disposed in the opening. A booster antenna is in communication with the transponder chip module. The device may include at least one fiber-reinforced epoxy laminate material layer. The transponder chip module and the booster antenna may comprise components in a payment circuit, with the metal layer electrically isolated from the payment circuit. The booster antenna may be formed on or embedded in the fiber-reinforced epoxy laminate material layer. Processes for manufacturing transaction devices including a metal layer with one or more fiber-reinforced epoxy laminate material layers are also disclosed.

摘要： An assembly is provided for a gas turbine engine. This gas turbine engine assembly includes a split case structure. The split case structure includes a first wall, a second wall, a first case segment and a second case segment. The first wall extends axially along and circumferentially about an axial centerline. The second wall extends axially along and circumferentially about the axial centerline. The second wall is radially outboard of and axially overlaps the first wall. The first case segment is configured to form a first portion of the first wall and a first portion of the second wall. The second case segment is configured to form a second portion of the first wall and a second portion of the second wall. The second case segment is circumferentially adjacent and attached to the first case segment at a joint.
