Abstract: A spark plug comprising a housing, a ceramic insulator and a sleeve is provided. The housing has an inner cavity while the ceramic insulator encloses a central electrode. The ceramic insulator is disposed inside the inner cavity and maintain from the housing with a gap. The sleeve is provided enclosing an inner wall of the housing and corresponds to an opening of the inner cavity. The level of an edge surface of the housing corresponding to the opening of the inner cavity is disposed higher than the level of an edge surface of the central electrode, and the level of the center electrode is also higher than the level of the edge surface of the ceramic insulator.

Abstract: A sink organizer includes a section defining a compartment having an extendable, collapsible and/or expandable base that provides a deeper holding section with an extended base to support a long slender shaped item, such as a long-handle brush. The expandable base has a telescopic structure, which may be in the form of an accordion-like structure having annular folding sections or other form of axially collapsible or telescopic structure (e.g., a concentric coupling of a series of nested and axially interlocking cylindrical collars of gradually reducing dimensions). Suction cups provide mounting of the sink organizer onto a sink wall. A bracket is attached to the side of the sink organizer where the suction cup mounting is also provided. The bracket has a handle, which is configured to rest against the top edge of the sink, thus providing additional support for stabilizing the sink organizer after it is attached to the sink wall by the suction cups.

Abstract: A portable navigation device is disclosed. The portable navigation device includes a global positioning module, a user interface, a destination obtaining means, a status obtaining means and a route generating means. The global positioning module generates a current position of the portable navigation device based on a global positioning signal. The destination obtaining means obtains a destination from the user interface. The status obtaining means obtains a user status from the user interface. The route generating means generates a suggested route based on the current position, the destination and the user status.

Abstract: A wireless communication system and a method for switching a base station (BS) thereof are provided. In the present invention, a globe positioning system (GPS) of a mobile apparatus is capable of obtaining a location information about the mobile apparatus. On receiving the location information transmitted from the mobile apparatus, a server end apparatus switches to a corresponding BS of a serving area where the mobile apparatus is located so as to serve the mobile apparatus.

Abstract: An exemplary punch die (30) includes a lower die (40) and an upper die (50). The lower die includes a die core (45), a blank holder (417), and a cylinder (413) disposed in the lower die. The blank holder is disposed on a periphery of the die core. The cylinder is connected to the blank holder and provides a constant force to the blank holder. The upper die includes a punch core corresponding to the die core. A punch machine using the present punch die is also provided.

Abstract: An exemplary film-removing device for removing a protecting film from a workpiece includes a main body and a film-removing mechanism. The film-removing mechanism includes a suspending arm and a roller. The suspending arm has a first end rotatably connected to the main body. The roller is rotatably connected to a second end, opposite to the first end, of the suspending arm. The roller is driven to rotate by movement of the workpiece.

Abstract: An exemplary flipping apparatus includes a slider, a flipping member and a holding table. The slider is slanted relative to the horizon. A first end of the flipping member is connected to the slider. The flipping member includes a first flipping plate and a second flipping plate facing the first flipping plate. The first flipping plate and the second flipping plate are contoured to define a workplace groove to receive a workpiece to be flipped. An angle defined by the slider and an end section of the first flipping plate opposite to the slider is less than an angle between the slider and the horizon. The holding table is connected to a second end of the flipping member, and the second end is opposite to that of the first end of the flipping member.

Abstract: A shelving system can include adjustable shelves with drain holes. The shelving system, which can be in the configuration of a shower caddy or shower organizer, can have shelf members with a plurality of flanges capable of attaching to horizontal connecting members on a separate central support member to allow for both lateral and vertical shelf adjustment. The shelving system can also have removable stainless steel shelf inserts with draining channels.

Abstract: A transport arm of the present disclosure includes a pneumatic cylinder and an acting arm. The pneumatic cylinder includes a main body, a piston rod, a piston and a guiding pin. A chamber is defined in the main body. The piston rod is partially received in the chamber of the main body. The piston rod defines a guiding groove therein, and a section of the guiding groove is slanted relative to an axis of the piston rod. The piston is fixed to the piston rod and partitions the chamber of the main body into two chambers. The guiding pin is fixed to the main body, and an end of the guiding pin adjacent to the guiding groove of the piston rod moveably engages in the guiding groove. The acting arm is fixed to an end of the piston rod opposite to the piston.

Abstract: An exemplary automatic materials sorting device (100) includes an input belt (11) for transporting materials, a materials sorting mechanism (12), and a control system. The materials sorting mechanism is connected to the input belt, and includes two output belts (121, 122). The input belt and the output belts are configured to transport materials. The control system includes two acting mechanisms (14, 15) and a controller (16). The controller is configured to control the acting mechanisms. The acting mechanisms are capable of creating a force to push the materials to the output belts.
