摘要:
A fabricating method of a shallow trench isolation structure includes the following steps. Firstly, a substrate is provided, wherein a high voltage device area is defined in the substrate. Then, a first etching process is performed to partially remove the substrate, thereby forming a preliminary shallow trench in the high voltage device area. Then, a second etching process is performed to further remove the substrate corresponding to the preliminary shallow trench, thereby forming a first shallow trench in the high voltage device area. Afterwards, a dielectric material is filled in the first shallow trench, thereby forming a first shallow trench isolation structure.

A plastic film applicator includes an applicator body including a mandrel and a grip connected to the mandrel, and a brake device including a bearing ring detachably mounted between the mandrel and grip of the applicator body for enabling the elastic braking pad to be biased toward the applicator body by an external force and an elastic braking pad having one end thereof connected to the bearing ring and elastically biasable by an external force. After the user attached a plastic film roll onto the mandrel of the applicator body, the user can press the thumb on the elastic braking pad to timely force the elastic braking pad toward the plastic film roll, forcing the abutment protrusion of the elastic braking pad into abutment against the film roll shaft, and thus, a braking effect is provided to the film roll shaft to stretch the extended plastic film for wrapping.

An adhesive tape dispenser capable of cutting an adhesive tape at a uniform length includes a suction cup for fastening to a tabletop, an operating handle operable to rotate a rotating wheel in pulling out an adhesive tape of a tape roll on the tape roller and to drive a gear set in rotating a cutter holder so that cutter blades at the cutter holder are moved into one of a series of cutting slots in the rotating wheel to cut the adhesive tape into multiple adhesive tape segments of the same lengths, and thus, the tape cutting efficiency is greatly improved. Further, the design of the suction cup enhances the operational stability of the adhesive tape dispenser.

A method for making a shoebox includes preparing a pulp tank and a mold which includes a first upper mold, a first lower mold and a second lower mold; a step of forming a flat sheet of a semi-final product which includes closing the first upper and lower molds to produce the semi-final product; a step of vacuum suction and mold movement which includes vacuum sucking the semi-final product to the first upper mold, moving the first upper mold to above the second lower mold; a step of hot pressing of the semi-final product into a flat sheet of a final product with patterns and fold lines by closing and heating the first upper mold and the second lower mold; and a step of separating the first upper mold and the second lower mold, taking out the final product and folding it into a shoebox.

A plate spring includes an internal surrounding portion, an external surrounding portion, and a plurality of suspending arms. The external surrounding portion surrounds the internal surrounding portion and is spaced apart from the internal surrounding portion. The suspending arms interconnect the internal surrounding portion and the external surrounding portion. Each of the suspending arms includes a first connecting segment, a second connecting segment, and a working segment. The first connecting segment is connected to the external surrounding portion and extends inwardly. The second connecting segment is connected to the internal surrounding portion and extends outwardly. The working segment interconnects the first and second connecting segments and is formed with a plurality of hole portions which are spaced apart from each other.

A shoe tree for one shoe includes a main body having a front end formed with a vamp support portion and a rear end formed with an upwardly extending rising portion and having a first side formed with a first side support portion and a second side formed with a second side support portion. Thus, the first side support portion has a shape matching that of the outer side of the shoe, and the second side support portion has a shape matching that of the inner side of the shoe so that the inner space of the shoe is supported by the main body of the shoe tree rigidly and stably, thereby preventing the shoe from being deformed due to its gravity.
