Abstract:
A hinge has a pintle, a moving leaf, a resilient device and a stationary leaf. The pintle has a resilient device mount formed on a distal end and is mounted securely in the stationary leaf. The moving leaf is mounted rotatably around the pintle and has a barrel having a protruding limit formed on an outer end. Because the resilient device mount is formed on the pintle, it does not break easily and may slip to prevent terminal failure and be reset when closed. The protruding limit abuts the stationary leaf and ensures a gap is formed between the leaves for wires cabling or the like. Therefore the hinge has improved wear and longer lifespan.

A magnetic memory device includes a substrate, a magnetic tunneling junction (MTJ) structure disposed on the substrate, and a capping layer disposed on the MTJ structure. By adding a capping layer on the MTJ structure, the property of the magnetic memory device is improved, the magnetoresistance (MR) ratio is raised, and the time cost by the magnetic memory device to process data is effectively reduced.
Abstract:
A sliding hinge for a portable device has a main bracket, a mounting panel and a plate spring assembly. The mounting panel is slid relative to the main bracket. A tether of the plate spring assembly is attached securely to the mounting panel. The mounting panel is attached securely to a cover of the portable device. A hub of the plate spring assembly is attached securely to a base of the portable device. When the cover is slid to open, the plate spring assembly forces the cover to be fully opened. Therefore, the cover slides to be fully opened without external forces.
Abstract:
A top-pinned magnetic tunnel junction device with perpendicular magnetization, including a bottom electrode, a non-ferromagnetic spacer, a free layer, a tunneling barrier, a synthetic antiferromagnetic reference layer and a top electrode, is provided. The non-ferromagnetic spacer is located on the bottom electrode. The free layer is located on the non-ferromagnetic spacer. The tunnel insulator is located on the free layer. The synthetic antiferromagnetic reference layer is located on the tunneling barrier. The synthetic antiferromagnetic reference layer includes a top reference layer located on the tunneling barrier, a middle reference layer located on the bottom reference layer and a bottom reference layer located on the tunneling barrier. The magnetization of the top reference layer is larger than that of the bottom reference layer. The top electrode is located on the synthetic antiferromagnetic reference layer.
Abstract:
A hinge assembly has a pintle, a torque assembly and a resistance assembly. The pintle has a head formed on the pintle. The torque assembly is mounted on the pintle at a first side of the head to provide a force to automatically open the cover relative to the body to a first angle. The resistance assembly is mounted on the pintle at a second side of the head to provide a frictional force to hold the cover at a second angle relative to the body when the cover is closed relative to the body. Accordingly, the cover can be pivoted open relative to the body automatically with the torque provided by the torque assembly.
Abstract:
A casing with magnetic latch that is easy to produce and a cover can be quickly opened. The casing has a first magnetic unit and a third magnetic unit respectively mounted in the cover and base. A second magnetic unit is slidably mounted between the first and third magnetic units. When the cover is closed, attraction between the first and third magnetic units holds the cover firmly against the base. When the second magnetic unit is slid between the first and third magnetic units, repulsion between the first and second magnetic units pushes the cover away from the base.
Abstract:
A hinge includes a housing. A sliding cam slideably received in the housing defines concave portions and an axial hole. A rotatable cam mating with the sliding cam has a base portion extending downward to form pushing portions disposed in the concave portions. The base portion defines an accommodating hole. A spring is slideably received in the housing. One end of the spring is fixed on the sliding cam and the other end of the spring is fixed at an end of the housing. A shaft received in the housing runs through the axial hole and the spring. An end of the shaft is received in the accommodating hole, and the other end of the shaft passes through the end of the housing. A first stop has a bottom surface whose part extends downward to form a blocking portion, and the rest part of the bottom surface is defined as a revolving platform. A second stop engaging with the rotatable cam has a top surface protruding upward to form a pushing block rotatablely disposed on the revolving platform. And a cap rotatablely receives the first stop and the second stop.
Abstract:
A hinge apparatus includes a hinge and a damper. The damper includes a damping shell, a damping body, an outer gasket and a pushing body, damping oil is filled in the damper. The damping shell has a cylinder-shaped shell body, a cover is formed in the top of the shell body, a sleeve is formed in the shell body, and an annual groove is defined between the shell body and the sleeve. The damping body has a bottom base, an annular sidewall, and a recess defined between the bottom base and the annular sidewall. The annular sidewall is received in the annual groove. The sleeve is received in the recess. Inner grooves are opened in the inside of the annular sidewall, outer grooves are opened in the outside of the annular sidewall. The outer gasket around the annular sidewall and below the outer grooves, the outer gasket is against the inside of the shell body. The pushing body is capable of pushing the damping body to rotate under the elastic force of the hinge.
Abstract:
A hinge apparatus includes a hinge housing, two sliding grooves are formed in the inner wall of the hinge housing. A shaft crosses the hinge housing. A sliding cam covers the shaft, an outer projection and an inner projection are formed in the lower of the sliding cam. The outer projection is positioned at an opening angle of 180 degrees to the inner projection. An engagement cam is accepted in the hinge housing, two ribs arranged in the two sides of the engagement cam match with the sliding grooves. The upper end of the engagement cam has an outer curved surface which is composed of an assurgent curved surface and a descending curved surface. The outer projection is against the outer curved surface.
