Abstract: The present invention relates to a method for reactive dyeing of leather, which includes: providing a reactive dye solution including at least one reactive dye and water, and making the reactive dye in the reactive dye solution to act on crust leather at a temperature from 25° C. to 70° C. to form covalent bonds between the reactive dye and the crust leather. Accordingly, the method for reactive dyeing of leather according to the present invention can enhance fastness and levelling property.

Abstract: A sputtering system aimed for sputtering workpieces that have non-planar surfaces, such as concaves, pillars, and steps of a case of a laptop. The sputtering system comprises a sputtering chamber including a carrier, a first sputtering source, and a second sputtering source. The first sputtering source is located over the carrier main to sputter planar portion of the workpiece. The second sputtering source is inclined at an angle so as to sputter the vertical portion of the workpiece.

Abstract: A shaking table assembly includes a plurality of first linear guides arranged in parallel with each other. A supporting table is slidably mounted on the first linear guides along a longitudinal direction thereof. A plurality of second linear guides are fixedly mounted on a top surface of the supporting table and are arranged in parallel with each other and perpendicular to the plurality of first linear guides. A testing table is slidably mounted on the second linear guides along a longitudinal direction thereof.

Abstract: A vibration suppression device includes a plurality of first elongated linear guides on which a first support table is slidably mounted. A first adjustable damping system is provided for damping slidable movement of the first support table on the plurality of first elongated linear guides. A plurality of second elongated linear guides are fixedly mounted on a top face of the first table and arranged perpendicular to the plurality of first elongated linear guides. A second support table is slidably mounted on the plurality of second elongated linear guides. A second adjustable damping system is provided for damping slidable movement of the second support table on the plurality of second elongated linear guides.
