Abstract: A disc brake caliper of a bicycle includes a main body, a first bolt, an intermediate member, a second bolt, and a tubing connector. The main body has an oil passage and a first tapped hole communicating with the oil passage. The first bolt is screwed into the first tapped hole, with a first exposed section exposed out of the main body. The intermediate member fits around the first exposed section through a first perforation, and has a second tapped hole, which extends in a direction different from that of the first perforation. The intermediate member can be rotated relative to the first exposed section. The second bolt is screwed in the second tapped hole, with a second exposed section exposed out of the intermediate member. The tubing connector fits around the second exposed section through a second perforation, and can be rotated relative to the second exposed section.

Abstract: A pet leash structure comprises a main leash body and a drag leash. The main leash body is weaved by a strap body and has a handle portion provided for a person to hold and a connection portion connected to a collar. A pull section is formed between the handle portion and the connection portion. The drag leash has a predetermined length and is connected to a tail end of the pull section. Therefore, a distance between the person and a pet may be fixed by pulling the drag leash so that the person may quickly drag the pet back by pulling the drag leash.

Abstract: A pet leash structure comprises more than one main leash body and more than one drag leash. The more than one main leash body is weaved by a strap body and has a handle portion provided for a person to hold and a connection portion connected to a collar. A pull section is formed between the handle portion and the connection portion. The more than one drag leash has a predetermined length and is connected to a tail end of the pull section. Therefore, a distance between the person and a pet may be fixed by pulling the more than one drag leash so that the person may quickly drag the pet back by pulling the more than one drag leash.

Abstract: A four-axial-fins fixed bed reactor for use with calcium aluminate carbonates CO2 sorbents is provided. The four-axial-fins fixed bed reactor includes a tubular reactor and a four-axial-fins tube. The tubular reactor has a tubular reactor inner wall. The four-axial-fins tube is disposed in the tubular reactor, wherein the four-axial-fins tube includes a tube and four axial fins. The tube has a tube outer wall. An annular space is formed between the tube and the tubular reactor. The four axial fins extend along the radial direction of the tubular reactor from the tube outer wall to connect the tubular reactor inner wall, wherein the annular space is equally divided by the four axial fins.

Abstract: A shoe structure having a lace capable for penetrating through itself mainly comprises a lace and a sole. The lace has a front end and a rear end. The lace includes at least one long weaving section weaved with one layer and at least two short weaving sections weaved with two layers for each. Each short weaving section has a gap. The lace has at least two gaps. The sole has a fastening portion arranged at each side thereof. It is characteristized in that a cover portion is formed by winding around the front end to penetrate through one gap of the lace, and a stop portion is formed by winding the front end with a loop to penetrate through the other gap, and then the front end and the rear end are fastened to the fastening portion of the sole.

Abstract: A white LED having a photoluminescent layer is provided, which includes a sapphire substrate, a gallium nitride buffer layer, an n-type gallium nitride layer, an aluminium gallium nitride multiquantum well, a p-type gallium nitride layer, a transparent conductive layer, a terbium-doped indium oxide layer as photoluminescent layer, a negative electrode, and a positive electrode, wherein the gallium nitride buffer layer, the n-type gallium nitride layer, the aluminium gallium nitride multiquantum well, the p-type gallium nitride layer, the transparent conductive layer, the terbium-doped indium oxide layer are sequentially formed on the sapphire substrate, and the negative electrode is formed on the exposed portion of the n-type gallium nitride layer and is electrically connected to the negative terminal V? of the power source, and the positive electrode is formed on the terbium-doped indium oxide layer and is electrically connected to the positive terminal V+ of the power source.
