Abstract: The present invention relates to a removable hard-disk structure without screws at least comprising a housing, a first elastic arm, a second elastic arm and a removable component. The housing having a placing space is connected to an opening end to enable the hard disk be placed into the placing space, and a door plate is further installed at the opening end to avoid the hard disk departing from the housing. The first and the second elastic arms are installed at the top surface and two side surfaces respectively, and these elastic arms are cantilever type and extend a pressing end into the placing space, which holds and presses the hard disk, and the hard disk is correctly being placed into the placing space. The removable component has a connecting end which is connected into the placing space, as the hard disk is placed in the placing space, the removable component fits the hard disk, and thus the hard disk can be easily removed by applying force on the removable end of the removable component.

Abstract: A transformer apparatus and a transformer shielding method are provided for shielding external electronic noises and protecting against erosion. The transformer apparatus comprises a toroidal core, a primary winding, a secondary winding, a protection tape, a metal foil, and an UL tube. The primary winding and the secondary winding are wound around the toroidal core at opposite side to each other. The protection tape is wrapped around the primary winding and the secondary winding. The metal foil encloses the protection tape. The UL tube enfolds the metal foil. The transformer shielding method comprises wrapping a primary winding and a secondary winding of the transformer apparatus by a protection tape, enclosing the protection tape by a metal foil, and enfolding the metal foil by an UL tube.

Abstract: A patched inverse F antenna (PIFA) antenna is provided. The PIFA antenna includes a ground portion, a radiation portion, a short-circuit portion and a feed-in portion. The width of the radiation portion is larger than the width of the ground portion, such that the operating band of the PIFA antenna covers at least a first band and a second band at the same time. The short-circuit portion is disposed on the ground portion and is connected to the radiation portion. The feed-in portion is connected to the radiation portion.

Abstract: A wireless apparatus and a method for configuring an access point with a wireless terminal are disclosed. The wireless apparatus comprises at least one access point with a SSID and a security key. The SSID has a default value and the security key has a null value. The access point is enabled when the wireless apparatus is in an initial status. The SSID and the security key are respectively set with predetermined values through the wireless terminal when the access point is enabled. When the setting of the SSID and the security key is done, the access point then is disabled.

Abstract: A large laminated structure includes a surface material, an ink layer, an adhesive layer and a release paper layer. The surface material has a bottom surface. The ink layer is disposed on the bottom surface in a predetermined pattern. The adhesive layer has a first planar surface and a second planar surface corresponding to each other. The adhesive layer has a plurality of channels connecting the first planar surface and the second planar surface. The first planar surface leans against and covers the bottom surface and the ink layer. The release paper layer is connected with the second planar surface. When the adhesive layer is attached to an attaching member, the gas between the adhesive layer and the attaching member may enter the channels of the adhesive layer such that the gas will not be trapped between the adhesive layer and the attaching member, thereby increasing the beauty of the attaching structure.

Abstract: An image processing method for providing an output image for an instant messaging program is provided. The image processing method includes the following steps. Firstly, an image capturer captures an input image. Next, the input image is inputted to a dump memory block. Then in response to an operating event, a drawing data is input to a canvas memory block. The storing sizes of the dump memory block and the canvas memory block are substantially the same. Next, the drawing data is obtained from the canvas memory and is combined with the input image, so that an output image is generated in the dump memory block. The instant messaging program controls a virtual image capturer to obtain the output image from the dump memory block.

Abstract: An external drive cabinet is provided with, a power connector and a data interface connector installed on the back side of the cabinet frame not on the same level but positioned in step manner, keeping a buffer space in between. Such arrangement of connectors enables one of the two connectors to make connection before the other does, thus smoothing out the plugging and unplugging processes. The tray in the external drive cabinet is equipped with a hinge joint at the rear end that is able to swing the front end of the tray upward when the handle bar of the tray is pulled up. The front panel of the hard disk stored in the drive cabinet can be completely concealed in the drive cabinet.

Abstract: A screwless mini fan holder is disclosed. The mount bracket of the fan holder is composed of two clips and four resilient pins projecting from opposite sides of a backplane. The clips are used to couple the fan holder onto the heat sink of a computer. The resilient pins each having a semi-circular ball head are used to attach the mini fan, where one end of each pin is permanently connected to the back side of the backplane, and the other end extends outward at an inclined angle. Such screwless design enables the fan holder without using any mechanical tools. This not only simplifies the assembly of the mini fan in a computer for most computer users, but also allows air flow to be uniformly distributed over the heat sink for maximized heat dissipation.

Abstract: A cardan shaft structure with tightness adjustable functions has a through-hole passing through spheres located at both ends of the cardan shaft body, and a taper socket respectively installed into the opening end of each sphere. A bolt is inserted into both spheres and the body, fixed and locked together in conjunction with a nut. The cardan shaft structure works together with two clamping components wrapping around the spheres. When the sphere is being pushed against (or freed from) the inner wall of the clamping component by tightening (or loosing) the bolt so as to make the sphere either expand (or recover), the angle displacement of the clamping component becomes adjustable accordingly.

Abstract: A retractable plug of power supply is comprised of a slide seat and a plug body. The slide seat is snap-fastened in a housing and metal pieces are arranged on sides of the plug body. An elastic lamella is disposed above the plug body, and a wedge block is located on the elastic lamella. The housing has a slot and a positioning hook part is provided on an inner wall face of the housing. A pushbutton is combined to the elastic lamella through the slot. The plug body is slidable in the slide seat by pushing the pushbutton in order to stretch metal pieces out of the housing. The metal pieces are prevented from being withdrawn into the housing by way of mutual retaining of the wedge and the positioning hook part, and such retaining could be released by pressing down the pushbutton to allow the withdrawal of the metal pieces into the housing.
