Abstract: A cover for a photoresist container includes a cap assembly and a threaded connector. The cap assembly includes a mounting plate, a connecting base and a cover plate. The mounting plate has a bottom surface, a top surface and a central hole defined through the mounting plate. The connecting base is mounted in the central hole of the mounting plate and abuts the bottom surface of the mounting plate. The cover plate is mounted on the top surface of the mounting plate and is connected to the connecting base. The threaded connector is connected detachably to the mounting plate and has a passing hole defined through the threaded connector and having an inner thread. When the inner thread of the threaded connector is worn off or damaged, the threaded connector can be detached and replaced easily and conveniently.

Abstract: A brake fluid reservoir for a braking system has a body and a fluid level detector. The body is hollow, single-piece molded and has a top, a bottom, two sides, a chamber, a fluid inlet and two fluid outlets. The chamber is defined in the body and has an inner surface. The fluid inlet is defined in the top and communicates with the chamber. The fluid outlets are defined respectively near the two sides in the bottom of the body and communicate with the chamber. The fluid level detector is mounted in the body and has two baffles to divide the chamber into two spaces communicating respectively with the fluid outlets. Because the body is single-piece molded, structural strength of the reservoir is enhanced.

Abstract: A hanging device with a sucker assembly has a sucker assembly and a hanging segment. The sucker assembly has a diaphragm, a sucker mount having an proximal end and being connected to the diaphragm, a sucker cover mounted around the sucker mount and abuts the diaphragm, an adjuster that screws around the sucker mount and a connector. The hanging segment has an end and a connector. The connectors of the sucker mount and the hanging segment connect to each other and may be a threaded rod engaging a threaded hole, a split plug held in a socket or be a protrusion engaging a recess. Therefore, the hanging device is hung firmly in a ceiling, a wall or the like by the sucker assembly.
