Abstract: A method for breeding Musca Domestica includes placing imagoes of Musca Domestica in an environment having a temperature of 18-35° C. and having a humidity of 50-80%. A laying pan is provided to attract the imagoes of Musca Domestica to lay eggs in the laying pan. The laying pan includes substances capable of attracting the imagoes of Musca Domestica to lay eggs in the laying pan. The eggs are transferred into a cultivating material including at least one product of soybean and/or milk. The eggs of Musca Domestica are bred at a temperature of 20-35° C. until hatching into larvae. The larvae are placed on swine feces and bred at a temperature of 20-35° C. for 2-3 days. The yield and breeding speed of the larvae of Musca Domestica are increased by the method.

Abstract: A sliding hinge is mounted between a cover and a body of an electronic device and has a bracket, a linking panel, a slide and a connecting wire. The bracket is attached securely to the cover. The linking panel is attached securely to the body and is mounted slidably on the bracket. The slide is mounted slidably on the bracket. The connecting wire is wound around a fulcrum of the bracket and respectively connects to the linking panel and the slide. The cable of the electronic device is mounted through the slide. When the cover slides relative to the body, the slide and the linking panel relatively move in opposite directions. Therefore, the cable is folded to keep taut.

Abstract: A weightlifting apparatus has multiple disc weights. Each disc weight has a round base and a round cover assembled on the round base. The round base has multiple locating slots formed therein. The round cover has multiple locating holes formed therethrough. When the locating slots align with the locating holes, lightweight weight plates or coins can be inserted into corresponding locating slots. When the locating slots misalign with the locating holes, the inserted weight plates or coins can be retained in the locating slots. Accordingly, easy weight adjustment and cost-saving effect can be achieved without requiring users to purchase an entire set of disc weights. With incremental fine weight adjustment of weight plates and coins, users can quickly adapt to the adjusted weight, and the exercise injury caused by large increment of weight adjustment can be avoided.

Abstract: An adjustable lumbar support assembly for a chair includes a base, a lumbar support, and an angle adjustment assembly. The base is formed at a lower end of the backrest of the chair. Bar sections bilaterally formed at a lower end of the lumbar support are positioned across the base. The angle adjustment assembly is connected with one bar section of the lumbar support and the base. To tilt the lumbar support forward or backward, a pulling rod is pulled backward to bring the lumbar support into a free state where projections on corresponding surfaces of a positioning element and a moving element mounted around the pulling rod are pressed against each other to allow manual adjustment of the lumbar support for optimal support. When the pulling rod is pushed back, the lumbar support enters a locked state where the positioning element and the moving element are in projection-recess engagement.

Abstract: A collapsible bicycle (1) has a frame (2) collapsible in its plane. The frame (2) includes a head tube (3) having a collapsible bicycle front side end (10) in which a front wheel fork (12), which receives a front wheel (13), is mounted. A seat stay (5) has an end (38) receiving a seat tube (39). A lever (6) is articulated at a first articulation point (50) at a collapsible bicycle rear side end (37) of the head tube (3) and at a second articulation point (49) at the end (38) of the seat stay (5) receiving the seat tube (39). The lever (6) is arranged to the collapsible bicycle front side in a riding position of the collapsible bicycle (1). A down tube (4) is articulated at a third articulation point (18) at the collapsible bicycle front side end (10) of the head tube (3) and at a fourth articulation point (24) at an end (38a) of the seat stay (5), opposite the end (38) of the seat tube (39).

Abstract: A high-efficiency water boiler includes a shell and a heating unit located in the shell. The heating unit includes a heating tank filled with fuel and a heater for heating the fuel. A containing unit includes a container provided around the heating tank. A heat conduction unit includes heat conduction pipes leading to the container from the heating tank to transfer heat to the container from the heating tank. A cooling unit includes a heat exchanger for cooling the fuel going therein from the heating tank. An inlet pipe extends through the heat exchanger and includes an end connected to a leading section of the container so that water can go into the container through the inlet pipe. An outlet pipe is connected to a tailing section of the container so that the water can leave the container through the outlet pipe.

Abstract: A water inlet/outlet assembly for a faucet includes a fore-injection molding dividing unit, a post-injection molding connecting unit and at least one supply pipe. The fore-injection molding dividing unit includes at least one water inlet pipe and a water outlet pipe. The water inlet pipe has at least one catch portion, at least one limit opening and at least one retaining slot. The post-injection molding connecting unit coats the water inlet pipe and is combined with the catch portion, the limit opening and the retaining slot to enhance combination strength between the post-injection molding connecting unit and the fore-injection molding dividing unit. The supply pipe has at least one axial breach, at least one mortise and two journals. The post-injection molding connecting unit coats the supply pipe and is combined with the axial breach, the mortise and the journals.
