An adjustable link for bracelets, including a first half link and a second half link arranged to be assembled to move with respect to each other, including an adjustment, and a locking mechanism cooperating with a complementary locking mechanism in order to form a captive assembly. The adjustment includes a screw, a hole passing through the first half link, and a blind threaded hole extending into the second half link, the through hole and the blind threaded hole facing each other, and being arranged to cooperate with the screw to continuously adjust the position of the first half link and of the second half link in the longitudinal direction in order to adjust the position between a maximum position and a minimum position.

A support and carrying apparatus for a cellular phone including an adjustable strap and a snap buckle fastener having a male member attached to a right end of the strap. A top end of each of a right second strap and a left second strap of a pair of second straps is attached to a female member of the snap buckle fastener and a left end of the strap, respectively. Each of a right mounting base and a left mounting base is attached to a bottom end of each of the right second strap and the left second strap, respectively. Each of a right arm support and a left arm support of a pair of telescopic arm supports is pivotably attached to each of the right mounting base and the left mounting base, respectively. A middle arm support is attached to the right arm support and the left arm support.

A multiuse bracket and support device for securing supports to a structure includes a band, which is flexible, that has a first end, a second end, opposing side edges, a front and a back. Each of a plurality of first couplers is coupled to the band. A first fastener is coupled to the back proximate to the first end, and a second fastener is coupled to the front proximate to the second end. The second fastener is complimentary to the first fastener. Each of a plurality of brackets comprises a second coupler coupled to a support. The second coupler is complimentary to the first coupler.

A hybrid chain belt which includes a toothed rubber belt and a pair of chains comprising a plurality of interleaved or laced sets of inner chain links and a plurality of interleaved outer or external links immediately adjacent the inner links mounted to the sides of the toothed belt. Each of the inner links and outer links has a pair of spaced apertures for receiving at least one pin which passes through the apertures of the links. The pins extend through the teeth of the rubber belt. Alternatively, the pair of chains may be replaced with outer links with either two apertures or a single aperture.

Problem. To provide a chain pin which makes it possible to improve wear resistance even in an environment in which degraded oil is used. Solution. A large number of pins are mixed/agitated together with a particle mixture including a penetrant comprising chromium (Cr) powder and tungsten carbide (WC) powder, and an iron chloride (FeCl.sub.3) catalyst, and WC particles penetrate the surface of the pins together with chromium carbide (CrC). As a result, a chromium carbide layer in which WC particles are diffused in a CrC layer (CrCWC layer) is formed on the outermost surface part of the steel forming the parent material of the pins.
