A negative coupling structure applied in a dielectric waveguide filter includes an elongated blind hole formed on a first surface of a dielectric body for building the negative coupling structure, and tuning holes formed on the first surface or a second surface of the dielectric body. A first coupling portion configured to be corresponsive to a bottom wall of the elongated blind hole, a second coupling portion configured to be corresponsive to a side wall of the elongated blind hole, and a common coupling portion connected between the bottom wall and the side wall are provided to define a negative coupling structure in the dielectric body, so as to provide both capacitive coupling and inductive coupling and a negative coupling and achieve the effects of reducing the weight and volume of the dielectric waveguide filter and providing good performance, simple structure and easy manufacture.

The invention herein relates to an improved tire structure comprised of a plurality of thin steel plates crisscrossingly arranged in the thick portion of a tire surface and an assembly of cover tire installed around the surface of said tire; the plurality of up and down crisscrossingly arranged thin steel plates form a shield along the circumference of tire that removes the worry of the tire being punctured by sharp objects on the roads when the vehicle travels, thus enhancing driving safety; the cover tire can be replaced after it is worn out without the need to change the whole tire, thus effectively reducing the consumption of rubber for tire production that makes the invention herein both economical and environmentally friendly.

Tire structure

The invention herein relates to a composite tire comprised of a rubber tire mounted over a rim which is covered externally by an assembly of cover tire having the following features: the cover tire is internally lined with a steel jacket that totally removes the risk of puncture; said cover tire is supported by the inflated tire and in contact with ground surface in rubber material that allows its usage by vehicles completely barrier-free; in addition, said cover tire uses significantly less rubber than regular tires and is replaceable anytime after wear without the need to change the entire tire. It not only effectively lowers the consumption of rubber, thus is both economical and environmentally friendly.

An improved clamp device structure for the clinching and conveyance of unusually shaped objects is provided and includes support rods equipped with steel clamp bars, of which the odd-numbered elements are fixed and the even-numbered elements are capable of leftward and rightward movement, or the even-numbered elements are fixed and the odd-numbered elements are capable of leftward and rightward movement. Installed at the upper extent of the support rods is a relief bar capable of the upward and downward movement that facilitates the clinching and conveyance of the unusually shaped objects. Since the steel clamp bars on the support rods are arrayed in a close configuration, the clinching range of the array is sufficient to accommodate a number of working objects and thereby enable the steel clamp bars to positively hold objects for conveyance. Furthermore, when utilized to release the working objects, the relief bar continues to descend and exert force against the top of the steel clamp bars, effectively releasing the working objects more smoothly and accurately.
