  • Patent number: 10216148
    Abstract: A wearable device made by amorphous alloy with antibacterial function includes a functional part adapted for implementing using functions of the wearable device; and an amorphous alloy housing configured out of the functional part and adapted for cladding the functional part to prevent the functional part from directly contacting with a user. Since the wearable device has the amorphous alloy housing covering on the functional part, thus the amorphous alloy housing rather than the functional part will contact with the user skin directly. As the amorphous alloy has excellent bactericidal capability, thus user wearing such a wearable device will get a good user experience.

    Abstract: Bipolar wave current, is used to electrodeposit a nanocrystalline grain size. Polarity Ratio is the ratio of absolute value of time integrated amplitude of negative and positive polarity current. Grain size can be controlled in alloys of two or more components, at least one of which is a metal, and at least one of which is most electro-active. Typically, the more electro-active material is preferentially lessened during negative current. Current density, duration of pulse portions, and bath composition are determined with reference to relations showing grain size as a function of deposit composition, and deposit composition as a function of Polarity Ratio, or a single relation showing grain size as a function of Polarity ratio. A specified size can be achieved by selecting a corresponding Polarity Ratio. Coatings can be layered, each having an average grain size, which can vary layer to layer and also graded through a region.

There are two kinds of active materials, titanium together with rare earth elements and magnesium. The metal substrate is composed of a main component and an additive. The main component is tin-zinc alloy and the additive is selected from bismuth, indium, silver, copper or their combinations. The active solder enables targets and backing plates to be joined with each other directly in the atmosphere. The target is ceramic or aluminum with low wetting properties. The bonding temperature of the active solder ranges from 150° C. to 200° C. so that the problem of thermal stress can be avoided.

  • Patent number: 8535441
    Abstract: A lid for a crystal growth chamber crucible is constructed by forming arcuate sector-shaped portions and coupling them in abutting relationship, for example by welding, to form an annular profile fabricated lid. The arcuate sector-shaped portions may be formed and removed from a lid fabrication blank with less waste than when unitary annular lids are formed and removed from a similarly sized fabrication blank. For example, the sector-shaped portions may be arrayed in an undulating pattern on the fabrication sheet.

  • Publication number: 20130114059
    Abstract: A metal component (262M, 300M) is designed for use in an EUV lithography apparatus, for example as a spectral purity filter (260) or a heating element (300) in a hydrogen radical generator. An exposed surface of the metal is treated (262P, 300P) to inhibit the formation of an oxide of said metal in an air environment prior to operation. This prevents contamination of optical components by subsequent evaporation of the oxide during operation of the component at elevated temperatures.
