Abstract: In an embodiment, a chemical mechanical planarization (CMP) system includes: a monolithic platen within a platen housing, wherein the monolithic platen is formed of a single piece of material, wherein the monolithic platen includes: a first portion within a first opening, and a second portion within a second opening, wherein the first portion has a different diameter than the second portion; and a polishing fluid delivery module above the monolithic platen, wherein the polishing fluid delivery module is configured to deliver slurry to the monolithic platen during performance of CMP.

Abstract: An umbrella structure with lighting device comprising a hollow shaft, a plurality of radial arranged stretchers mounted to the hollow shaft, a layer of fabric covered onto the stretchers, a light-emission device mounted at the tip of the hollow shaft, a handle connected at the bottom end of the hollow shaft, and a power supply device mounted with the handle, characterized in that the light-emission device comprises a light transmissive tube cover screwed at the tip of the hollow shaft, a light-emission body mounted within the tube cover, a fluorescent plate positioned between the light-emission body and the tube cover, and a stopper mounted at the top cover of the tube cover, the light emission body is lighted to flicker and the intensity of the emitted light is increased as a result of reflection and refraction by fluorescent body positioned within the fluorescent plate, the fluorescent light is emitted through the transparent tube cover to provide an alarming effect in the night.

Abstract: A retractable umbrella jacket structure which can be assembled and disassembled comprising a water-guiding plug, water-collection collar and umbrella jacket, screw ring, the water-guiding plug allowing the tip of the umbrella to pass through and being secured, and the water-guiding plug passed through the water-collection collar, and the umbrella jacket being a plurality of tapered mounting rings, characterized in that the top end of the water-collection collar is mounted with a hollow screw seat, after the first mounting ring is mounted onto the water-collection collar, screwed ring is secured to the screw seat such that the umbrella jacket is engaged at the water-collection jacket, and if the screwed ring is removed, the umbrella jacket is disengaged from the water-collection jacket, and the hollow screw seat of the water-collection jacket is mounted with a spring and a water-discharging valve, the water discharging valve is a hollow cap extended with a teeth-like valve rod having an inverted hook at the to

Abstract: A telescopic umbrella case which possesses water-collecting function and light-reflecting effect for enhancing the safety of a user when walking at night. The umbrella case is composed of an innermost top sleeve member and several subsidiary sleeve members which are telescopically assembled and able to be extended into an elongated state for entirely covering an umbrella. A resilient water-draining valve is disposed at a top end of the first sleeve member. The water-draining valve includes a valve rod and a valve body. The valve rod is pressable against the ground to push the valve body away from a water-draining hole of the top sleeve member, permitting the rain water collected therein to flow through the water-draining hole down onto the ground.
