A method of manufacturing a door hinge, which can improve productivity by applying both metal injection molding and additive manufacturing is disclosed. The method includes: preparing a first mixture of a first metal powder and a first binder, and a second mixture of a second metal powder and a second binder; molding the first mixture into a first body including a first connection member having a first pinhole; molding the first mixture into a second body including a second connection member having a second pinhole to communicate with the first pinhole; arranging the first body and the second body to align the first pinhole and the second pinhole along an axis to form a cavity; forming a pin member with the second mixture in the cavity by adding up droplets of the second mixture in the cavity; and sintering the first body, the second body, and the pin member.

A door includes a rectangular panel having a first face, a second face, and two pairs of opposing edges, in which the edges of each pair of edges are parallel and in which a first pair of edges is longer than a second pair of edges. The rectangular panel includes a layered composite material, in which a first layer of the composite material has a positive Poisson's ratio (PPR) and a second layer of the composite material is disposed in contact with the first layer and that includes a material having a negative Poisson's ratio (NPR). The door includes a hinge including plates joined together by a joint, in which a first one of the plates is attached to a first one of the edges of the first pair of edges and in which a second one of the plates extends beyond the first one of the edges. The door also includes a handle opening defined through a thickness of the rectangular panel.

A beam with a hybrid cross-sectional structure is provided. The beam includes a first section having a first cross-sectional I-beam structure, a second section having a second cross-sectional box-beam structure and a third section. The third section is interposed between the first and second sections and incorporating the first and second cross-sectional I-beam and box-beam structures.

A hood hinge structure includes a hood hinge base (12) and a hood hinge arm (14). The hood hinge base is fixed to a vehicle body. The hood hinge arm includes a supported portion (22) and a fixed portion (24). The supported portion is provided at a base end side of the hood hinge arm and is supported by the hood hinge base. The fixed portion (24) is provided at a tip end side of the hood hinge arm and is fixed to a hood. At least a portion of the hood hinge arm from the supported portion to the fixed portion has a laminated structure.

A surgical table comprising a base and a patient support supported between opposed ends of the base, each opposed end including a pitch/roll assembly. The base is configured such that the patient support can be rolled and pitched relative to the opposed ends via the pitch/roll assemblies such that the roll axis of each pitch/roll assembly remains coaxial regardless of how the patient support is pitched or rolled relative to the base. The patient support includes an outer frame and an inner frame supported on, and displaceable relative to, the outer frame. The inner frame is further articulating about, and relative to, itself. The outer frame is rigid in that it does not change configurations.
