Abstract: A protective film for back-grinding wafers primarily includes a base layer and a multi-film structure. The multi-film structure at least includes two TPU films, wherein the one (HPTU film) having a higher Vicat softening temperatures and/or heat deflection temperature than the other (LPTU film) contacts the base layer. The protective film optionally includes an adhesive film on one side of the LTPU film. The multi-film structure may include one or more TPU films between the HPTU and the LPTU films.

Abstract: A cabinet holding structure, the slide rails are disposed on the frames and have troughs. Supporting components are assembled on ends of the slide rails. Each supporting component includes a positioning plate, a screw nut, a supporting plate, a stud and a screw bolt. The positioning plate has a through hole and is placed on the slide rail, and the supporting plate is plated on another side of the slide rail. The stud protrudes through the trough. The screw bolt passes through the trough and the through hole to be fixed by the screw nut. The chassis includes a shell and notches. The shell is positioned on the slide rails by buckling the notches and the stud together.

Abstract: A hard drive rack includes a frame. The frame includes a plurality of plates surrounding to form an accommodating space and at least one insertion opening. The plates include a bottom plate, a cover plate, and a supporting plate. The latch arm of the actuator assembly includes a first buckle part and is pivotally connected to the frame. The buckle arm includes a pivotal end and a hooking end, the buckle arm connects to the bottom plate through the pivotal end and is able to pivotally rotate. The hooking end is formed with a second buckle part which is selectively blocked by the first buckle part to encircle the insertion opening.

Abstract: A fixing member (100) of a rack server includes a chassis slide assembly (200), a main body (102), and a fixing column (110). The main body (102) is disposed on an end of the chassis slide assembly (200), one side of the main body (102) is connected to a first positioning element (104), and another side of the main body (102) is connected to a second positioning element (106). The second positioning element (106) is disposed corresponding to the first positioning element (104). The fixing column (110) is disposed on the main body (102) and one end thereof is fixed onto the chassis slide assembly (200). The main body (102) is able to rotate along the fixing column (110) as an axis. The first positioning element (104) and the second positioning element (106) have different shape. Therefore, the same chassis slide assembly (200) can match a different server rack.

Abstract: A sheet guiding apparatus assembled on a shelf includes two guiding members, two adjusting plates, a first spring, two push bars, a second spring and two rotating members. The guiding member has a base board. A front of the base board defines a guiding portion defining a horizontal recess. Each adjusting plate is pivoted to an outside edge of the base board. The push bars are movably received in the horizontal recesses and capable of sliding in the horizontal recesses to drive the corresponding adjusting plates to rotate upward or free the corresponding adjusting plates therefrom. Each rotating member is pivoted to a front of the guiding portion. When the rotating member is turned down, the rotating member touches the push bar and pushes the push bar to move rearward so that further drives the adjusting plate to rotate upward till being perpendicular to the base board.

Abstract: Short message-based terminal communication systems and methods are provided. The system includes a transmission terminal, a central server, and at least one reception terminal. The transmission terminal generates a short message, and transmits the short message to the central server. The short message includes a service identifier, an application parameter, contents, and at least one reception terminal. The central server parses the short message, and transmits the short message to the at least one reception terminal. After the short message is received, the reception terminal determines whether the service identifier conforms to a predefined service identifier. If so, the reception terminal launches a specific application procedure according to the application parameter, and displays the contents of the short message in the specific application procedure.

Abstract: An automatic alarm device for dripping injection fluid bottle, which is installed in the bottle neck portion, and it comprises of a case body, a buoyant power switching device, a buzzer, and a flashing device.

Abstract: A music tooth brush comprises a hollow brush hair stock, a touch switch containing the hollow part of said brush hair stock, a brush hair board floatingly mounted on the brush hair stock, and a hollow grip handle bar containing the music IC, batteries and sound-generating plate. When the user brushes his teeth with the said tooth brush, the brush hair board can touch and press the touch switch in the brush hair stock to make the circuit in the grip handle bar become electrically conductive, so the sound-generating plate automatically generates the children's favorite music to eliminate their sense of ill feeling against brushing their teeth and further to foster in children a good habit of brushing their teeth after eating.
