A mounting assembly (101, 201, 301, 401) for mounting an accessory (102, 202, 302, 402) is provided. The mounting assembly (101, 201, 301, 401) includes a mounting bracket (103, 203, 303, 403) with an aperture arranged to receive a fastener for fastening the mounting bracket (103, 203, 303, 403) to a surface. A supporting structure is provided between the mounting bracket (103, 203, 303, 403) and the accessory (102, 202, 302, 402) with an elongate hollow member (107, 207, 307, 407) substantially surrounding the supporting structure. The elongate hollow member (107, 207, 307, 407) is releasably secured to the mounting bracket (103, 203, 303, 403) with the mounting bracket (103, 203, 303, 403) and the elongate hollow member (107, 207, 307, 407) having complementary male-and-female mating formations which are arranged to inhibit rotation of the elongate hollow member (107, 207, 307, 407) relative to the mounting bracket (103, 203, 303, 403).

A rebar anchoring system and method are provided. The system includes: a rebar, with an external thread formed on the periphery of at least one end; an anchoring head, with a first perforation and a second perforation disposed respectively at both ends extending axially into the anchoring head and communicating with each other, the inner sides of the first and second perforations being formed respectively with a first internal thread matching with the external thread of the rebar and a second internal thread, and the anchoring head being mounted on the end of the rebar through the first internal thread and the external thread of the rebar; and a bolt, having a screw rod matching with the second internal thread, the screw rod being locked into the second perforation of the anchoring head, and the end of the screw rod pressing against the end of the rebar.

A ceiling fan motor housing includes a bottom cover member, a hollow housing member, and a plurality of screws. The bottom cover member is formed with a plurality of threaded holes. The housing member is formed with a plurality of L-shaped positioning members extending from a bottom end thereof. Each of the positioning members has a vertical portion which is connected to the bottom end of the housing member and a horizontal portion which extends inwardly from a bottom end of the vertical portion, supports the bottom cover member, and is formed with a positioning hole. The screws respectively extend through the positioning holes of the positioning members to respectively engage the threaded holes of the bottom cover member.

A method for manufacturing an electrostatic chuck with multiple chucking electrodes made of ceramic pieces using metallic aluminum as the joining. The aluminum may be placed between two pieces and the assembly may be heated in the range of 770 C to 1200 C. The joining atmosphere may be non-oxygenated. After joining the exclusions in the electrode pattern may be machined by also machining through one of the plate layers. The machined exclusion slots may then be filled with epoxy or other material. An electrostatic chuck or other structure manufactured according to such methods.
