Abstract: An optical component includes a substrate and a low reflection layer. The low reflection layer is disposed on a surface of the substrate, and the low reflection layer includes a plurality of nanoparticles. The nanoparticles are arranged in a stack configuration, and the number of the nanoparticles decreases progressively in a direction away from the substrate, such that an effective refractive index of the low reflection layer decreases progressively in the direction away from the substrate so as to prevent total reflection of light at the interface, thereby reducing reflectivity. When specific conditions are satisfied, the stacked nanoparticles can form a gradient-index film layer, and the low reflection layer can provide better anti-reflection capability.

Abstract: A cleaning robot includes a main body and a cleaning module. The main body is configured to move on a floor along a travelling direction. The cleaning module includes a first shaft and some first roller sets. The first shaft is connected with the main body. The first shaft extends along a first axis perpendicular to the travelling direction. The first roller sets are separated from each other. Each first roller set includes a first bearing, a first tire and a first flexible structure. The first shaft penetrates through the first bearing. The first tire includes a first cleaning surface configured to abut against the floor. The first flexible structure includes a first inner surface and a first outer surface. The first inner surface abuts against the first bearing. The first outer surface abuts against the first tire. The first flexible structure has a first elasticity.

Abstract: Disclosed is an IC layout design method capable of improving a result of an integrated circuit (IC) layout design process including a front-end process and a back-end process. The IC layout design method includes the following steps: executing the front-end process according to an initial clock latency setting and thereby generating an initial netlist; executing at least a part of the back-end process according to the initial netlist and thereby obtaining an updated clock latency setting; executing at least a part of the front-end process according to the updated clock latency setting and thereby generating an updated netlist; and executing the back-end process according to the updated netlist and thereby obtaining the result of the IC layout design process.

Abstract: An ice shaver structure includes a worm shaft, an ice pressing tray installed at the bottom of the worm shaft for controlling ice block, a thread section formed on the worm shaft and engaged with a worm gear, a resisting mechanism installed on the worm gear and having a stopper fixed to an ice shaver and abutted against an axial surface of the worm gear, and a resilient device abutted against the stopper. The resilient device has a position-adjusting fixing element for determining an elastic force produced by the resilient device after being compressed, and the elastic force is acted on the stopper to push the stopper to press against the worm gear, such that the resilient device becomes a relative fixed end which is difficult to turn, so that the worm shaft can be driven by a motor to produced up-and-down displacements.
