Abstract: A carrier module of a tire pressure monitoring device includes a plastic carrier and a metallic tube. The plastic carrier has a trough and a tube extended from a bottom portion of the trough. The trough has an airflow channel penetratingly formed on the bottom portion thereof, and the trough is in air communication with the tube by the airflow channel The metallic tube is seamlessly formed on an inner surface of the tube of the plastic carrier. The metallic tube has an inner screw thread formed on an inner surface thereof for detachably screwing to a nozzle of a tire. Thus, by seamlessly forming the metallic tube on the inner surface of the tube of the plastic carrier, the tire pressure monitoring device of the instant disclosure has a better airproof effect and a longer service life.

Abstract: A method of fabricating a keycap, in which, a metal sheet is provided, and the metal sheet is pressed to form a plurality of keycap-shaped regions, each having a recess portion. The pressed metal sheet is subjected to laser cutting at each keycap-shaped region to form a pattern by cutting out a part of the metal sheet. The recess of each keycap-shaped region is filled with a transparent plastic material, and the metal sheet is punched to form separated keycap-shaped components. These two steps can be switched each other in the order. The separated keycap-shaped components may be each further combined with a pad, respectively.

Abstract: A safety syringe has a retaining device formed on a front end of the barrel, multiple bosses formed on the needle hub to rotatably correspond to the retaining device, multiple recesses defined inside the needle hub and multiple inclined teeth formed on the plunger to correspond to the recesses, such that the engagement between the retaining device and the bosses of the needle hub is able to be released by the rotational movement of the plunger together with the needle hub due to the combination of the inclined teeth and the recesses.

Abstract: A syringe has two groups of oppositely formed slip-proof straps axially formed on a periphery of the barrel so that when the user is holding the barrel to pull the recycled needle back into the barrel, the user is able to have a firm grip to the barrel. Further, the plunger of the syringe has a square head formed on a distal end of the plunger and extending out of the barrel so as to facilitate the user to pull the needle.

Abstract: A warehousing system includes a multistory building having at least one lower floor, at least one upper floor located above the lower floor, opposed pairs of rack members disposed on the upper floor, and an aisle formed between each of the pairs of the rack members. Each pair of the rack members has two opposed horizontal guide rails respectively formed thereon at two sides of the aisle. A hole is formed in the upper floor at the aisle to intercommunicate respectively with the lower floor. A conveying device is disposed movably on the horizontal guide rails. The conveying device includes a translation device having a base bridging the aisle and connected slidably to the horizontal guide rails, a driving device disposed on the base for driving the base to move along the horizontal guide rails in a first direction, a holding apparatus mounted on the base and adapted for holding an article to be conveyed, and an elevator apparatus disposed on the base for raising and lowering the holding apparatus from the base.
