Abstract: A swivel structure having direction indication is described. The swivel structure includes a first swivel base and a second swivel base. The first swivel base has at least a window and the second swivel base has at least a first direction indication mark and at least a second direction indication mark. The first swivel base and the second swivel base have a first fixed position state and a second fixed position state. The first fixed position state and the second fixed position state switch to each other by swiveling. When in the first fixed position state, the first direction indication marks are shown through the windows and indicate the direction toward the second fixed position state. When in the second fixed position state, the second direction indication marks are shown through the windows and indicate the direction toward the first fixed position state.

Abstract: A fastening structure for dissipation device has a metal plate with at least one screw hole, a screw with an engagement part, an elastic element, and a screw cap. The screw and the elastic apparatus are assembled in the screw hole. The screw cap, whose clamp structures are fastened to the outside of the screw hole, limits movement of the screw and the elastic element in the screw hole. The screw is allowed to move upward and downward within a predetermined scope.

Abstract: A hatch for an electronic device. The hatch comprises a main body, a thermal insulation layer, a conductive layer and an electrical insulation layer. The thermal insulation layer is disposed on the inner surface of the main body. The conductive layer fully covers the surface of the thermal insulation layer. The electrical insulation layer partially covers the conductive layer and a part of the conductive layer is exposed, wherein heat from the electronic device is insulated by the thermal insulation layer such that the temperature of the surface of the main body is controlled.

Abstract: A fixing assembly for connecting and fixing a hard disk drive to an electronic device. The fixing assembly includes a mounting bracket and a cover. The mounting bracket engages the hard disk drive. The cover flexibly connects the mounting bracket and engages the electronic device.

Abstract: A two-sided POP UP structure is employed to pop up a LCD screen of notebook/tablet PC while releasing. A display panel of a notebook/tablet PC is connected to a mainframe of the notebook/tablet PC via a hinge. The two-sided POP UP structure has a male part and female part. One end of the male part is fixed to the hinge, and the other end is a cylinder with a holding rib. One end of the female part is fixed to the display panel, and the other end is an elastic metal shaped around the cylinder of the male part. The elastic metal is cut to form a rotation slot for the holding rib. When the holding rib interferes with the elastic metal, the elastic metal deforms to allow the LCD screen to pop up more easily.

Abstract: A strap buckle apparatus fastened to a lock hole is employed to connect to a strap. The strap buckle apparatus comprises a rotation hub, a base, and a rotation plug. The rotation hub controls the rotation angle of the rotation plug. The base with a hole in the center connects to a strap. One end of the rotation plug is inserted into the lock hole, while the other end is fixed to the rotation hub.

Abstract: A magnetic locking device is described. The magnetic locking device is utilized for locking an electric device upper cover especially for locking both sides of the display cover of a notebook/tablet dual-purpose personal computer. The magnetic locking device has a lock module and a hook module. The lock module installed in the upper cover has a lock module base, a release button, a magnet, a first bezel and a second bezel. The hook module installed in the electric device base has a hook module base, a spring device, and a hook. The spring device pulls the hook to hide in the electric device base when the hook is not working to improve the electric device appearance and to eliminate interference during operation.

Abstract: A fastening structure for dissipation device has a metal plate with at least one screw hole, a screw with an engagement part, an elastic element, and a screw cap. The screw and the elastic apparatus are assembled in the screw hole. The screw cap, whose clamp structures are fastened to the outside of the screw hole, limits movement of the screw and the elastic element in the screw hole. The screw is allowed to move upward and downward within a predetermined scope.

Abstract: A rotatable display fixing module is described. The rotatable display fixing module has a first rotational device, a second rotational device, a fixing switch and an auxiliary fixing stud. The first rotational device rotatably connects with a display and the second rotational device. The fixing switch and the auxiliary fixing stud rebound up to fix the second rotational device at predetermined angles and the auxiliary fixing stud passes through a fixing hole on a rotational element of the second rotational device. The display can therefore rotate on the first rotational device only. When the fixing switch and the auxiliary fixing stud are pressed, the display can rotate on the first rotational device and the second rotational device.

Abstract: A swivel hinge with angular fixing structure is employed to connect a mainframe and a display means of a notebook computer. The swivel hinge has a fixture part, a fixture friction ring, a rotation part, a rotation friction ring, and an elastic ring. The fixture part mounted on the mainframe has a through hole in the center thereof. The fixture friction ring mounted on the fixture part has at least one holder on the surface. The rotation friction ring mounted on the rotation part has at least one slot in the surface thereof. The elastic ring is located between the fixture part and the fixture friction ring. If the slot and the holder on the friction ring fit into each other, the desired angular fixing function is provided.

Abstract: An ejection mechanism of a stylus in a portable computer is mounted on the bottom of the stylus slot. The stylus ejection mechanism comprises an elastic apparatus and a holder. The elastic apparatus fixed to the bottom of the stylus slot provides the ejection force for the stylus. The elastic apparatus can be a spring, a metal plate or a plastic arm. The holder provides a support for the stylus when it is inserted for storage.

Abstract: A fixing structure is employed to secure a stylus in a portable computer. The fixing structure has a storage slot, an attachment means, a latch and an elastic apparatus. An attachment means mounted on a stylus has an engraved notch. The latch embedded in the storage slot fits in the engraved notch of the attachment means to prevent the stylus from slipping out of the storage slot. The latch is pushed by the elastic apparatus.

Abstract: A rotatable display fixing module is described. The rotatable display fixing module has a first rotational device, a second rotational device and a fixing switch. The first rotational device rotatable connects with a display and the second rotational device. The fixing switch rebounds up to fix the second rotational device at predetermined angles and then the display can rotate with the first rotational device only. The module further comprises a locking device to lock the fixing switch when the fixing switch is pressed down. A linkage device can release the fixing switch from the locking device at the predetermined angles and then the fixing switch rebounds up due to a spring device.
