Abstract: A positioning device for positioning an abnormal tissue is provided. The positioning device comprises a positioning tube and a positioning suture accommodated in the positioning tube. When the positioning suture is injected into the abnormal tissue, a head portion and a portion of a body portion of the positioning suture are retained inside the abnormal tissue while the rest of the body portion being exposed outside the abnormal tissue, thereby marking a specific area accordingly to facilitate the subsequent excision process.

Abstract: An electronic device, comprises: a base including a top surface and a bottom surface; a baseplate, a side edge of the baseplate is pivotally connected with the bottom surface, a moving member disposed in the base and configured to push against the baseplate; a linkage member disposed in the base and configured to push against the moving member; and a push member disposed in the base, the push member makes the baseplate moved via the linkage member and the moving member in sequence to make the baseplate selectively cover the bottom surface or detached from the bottom surface.

Abstract: The utility model discloses a shoe with a shell structure. The shoe with the shell structure is comprised of two main components, namely, a shoe shell and a shoe body. The shoe body is comprised of an upper, a bottom and a wearing opening, while the shoe shell is comprised of a vamp upper, a sole, a wearing opening and a buckle assembly. The shell vamp upper and the sole form an inner space and the shoe body is just suitable for the inner space of the shoe shell. Therefore, a wearer can wear the shoe body and then put on the shoe shell. If the shoe shell or the shoe body is damaged after being used for a long time, only the damaged assembly is replaced. The other good assembly can be continuously used, saving material and protecting the environment. Furthermore, different designs of the shoe shell and shoe body can be produced, and the combination of shoe shell and shoe body can be exchanged and/or interchanged for the purpose of function, style or replacement.

Abstract: In a method of preparing a non-toxic anti-tacky water paint, nitrocellulose is solubilized in n-butyl acetate to form a nitrocellulose solution, which is then mixed with urea-formaldehyde and water to form a first mixture solution, which is then heated for two to three hours via water at a temperature of 65 to 90° C. so that the first mixture solution is separated into an upper layer of liquid and a lower layer of powder. Next, the upper layer is removed, and ethylene glycol monobutyl ether is added to the lower layer to form a second mixture solution. Then, a non-ionic surfactant is added to the second mixture solution to form a third mixture solution. Finally, the third mixture solution is added to a water-soluble paint to obtain the non-toxic anti-tacky water paint, which may be coated on a container object so that the object can be conveniently transported and stored.

Abstract: An integral shoe with a roller assembly. The integral shoe has an upper and a sole, which are integrally formed. At least one cavity is formed on the sole so that the roller assembly can be mounted in the cavity. Thus, the shoe with the roller function is integrally formed more quickly, and the roller assembly may also be replaced so that multiple functions can be achieved.

Abstract: A parent-child leadframe type transformer includes a ferrite core module, a child leadframe and a parent leadframe. The parent leadframe has a first opening and a second opening on both ends. The length of the second opening is greater than the length of the first opening along the same axial direction. A containing space is defined between the first and second openings. The child leadframe has a coil winding slot and a through hole for installing the ferrite core module. The axial length of the child leadframe falls between the first and second openings, such that the child leadframe and the ferrite core module can be passed through the second opening, but limited by the first opening. The child leadframe, ferrite core module and parent leadframe are positioned to define a parent-child type transformer structure for reducing the overall height and complying with the safety regulation standards.

Abstract: A roller skate shoe has cavities, closing members and roller assemblies. A sole of the shoe is formed with the cavities. Two sides of each cavity are formed with notched slots. The closing member is accommodated in the cavity. The closing member has a closing side for closing the cavity, and is formed with two cut edges corresponding to the notched slots. The roller assembly mounted on the closing member includes a roller base, a roller body mounted in the roller base, and two control assemblies respectively mounted to two sides of the roller base corresponding to the cut edges and the notched slots. The roller assembly is separated from the cavity using the control assembly so that the closing member may be detached from the roller and reversed to close the cavity to prevent foreign objects from entering the cavity.
