Abstract: A print circuit board and a manufacturing method thereof are disclosed. The print circuit board includes a first substrate, a first insulating layer and a metal sheet. The first insulating layer is formed between the first substrate and the metal sheet. The insulating layer includes silicon-based polymer compound. The manufacturing method for the print circuit board includes the following steps: coating a first substrate and a metal sheet with insulating material, placing the first substrate and the metal sheet into a heating device to bake the insulating material on the first substrate and the metal sheet, and bonding the metal sheet onto the first substrate through thermally pressing the baked insulating material. The insulating material includes silicon-based polymer compound.

Abstract: A length-adjustable snowshoe includes a frame and a carrier fixed to the frame. A connecting member mounted to the frame includes two receiving holes. A pivotal portion is formed on a top side of the connecting member. A compartment extends from the pivotal portion through one of the receiving holes. An extension member includes legs slideably received in the receiving holes and is slideable between first and second positions. A sliding member is mounted on the extension member to move therewith. A positioning member is received in the compartment and pivotable between a stop position and a releasing position. The positioning member in the stop position retains the extension member in any location including and intermediate the first and second positions. The extension member can slide between the first and second positions when the positioning member is in the releasing position.

Abstract: A buckle device for a skate comprises an adjustable receptor fixed to a side of an upper of a boot of a skate, a strap, and a tensioning/releasing mechanism. The tensioning/releasing mechanism comprises a base and a release arm. The base is fixed to another side of the upper of the boot and includes a pivotal seat on an end thereof. The release arm has a first end and a second end pivotally engaged with the pivotal seat. The strap has an end pivoted to the release arm. The release arm is movable between a tensioning position in which the release arm is retained in place relative to the base and the strap is tensioned and a detaching position in which the strap is not tensioned. The second end of the release arm is detachable from the pivotal seat when the release arm is in the detaching position.

Abstract: A buckle device for a skate comprises an adjustable receptor including a frame fixed to a side of a boot upper, a pin pivotally supported by the frame, a cover plate securely mounted on the pin, and a catch member securely mounted on the pin. A strap has an end extending through a space between the frame and an end of the catch member. The strap includes ratchet teeth on an inner side thereof. When in a normal state, the end of the catch member is biased to selectively engage with the stop face of one of the ratchet teeth of the strap, such that the strap is only movable along a tightening direction. When the cover plate is pulled outward, the end of the catch member is disengaged from the ratchet teeth of the strap, allowing the strap to be moved in a loosening direction.

Abstract: A skate board scooter includes a board having two mounting plates extended from an underside thereof. Two side plates are provided and each has a lower end extended through an opening of the board and securely attached to an associated mounting plate. A sleeve that rotatably holds a steering rod assembly includes two wings extended from an outer periphery thereof. Each wing is pivotally attached between the side plates. An engaging member includes a first end releasably engaged with notches defined in the wings and a second end pivotally attached between the side plates. A quick release assembly is mounted to the side plates for releasably retaining the wings in place relative to the side plates when the quick release assembly is in a locking state. The wings are pivotally movable relative to the side plates when the quick release assembly is in a release state.

Abstract: An ink cartridge including a case having an ink absorbent received therein and an ink-dispensing outlet provided at a bottom thereof, and a cover closing the case is provided. The cover is provided with at least an ink-filling hole, a vent hole vertically extending down into the case, and a capped ink-refilling hole. The cover is also provided at a bottom surface with a plurality of spaced transverse pressing ribs which alternately extend from two longer sides of the cover to end at points a distance exceeded a longitudinal centerline of the cover, such that a wound air path is defined below the cover by the pressing ribs for air entering into the case via the vent hole to evenly and smoothly flow throughout the case via the wound air path above the ink absorbent to ensure even and smooth supply of ink to the ink-dispensing outlet. And, a stop disc is mounted around a lower portion of the vent hole below the cover to prevent vaporized ink from entering into and thereby clogging the vent hole.
