A hermetic sealing approach involves welding an Aluminum cover onto a low-cost Aluminum housing. According to an example embodiment of the present invention, a metal housing having a base and sidewalls extending upward therefrom is adapted to receive and couple to an HDD arrangement. The metal housing is formed using material and processing (e.g., cold formed or die cast Aluminum) that are relatively inexpensive. A feedthrough arrangement including a plurality of communication pins extends through an opening in the base and is coupled thereto, with the communication pins adapted to pass signals between the inside and the outside of the metal housing. A metal cover is welded to an upper portion of the sidewalls and, with the feedthrough arrangement, hermetically seals the metal housing.

The invention discloses an antenna device for a full metal shell. The antenna device comprises a metal shell arranged at the back of communication equipment, antenna branches and feeding points, wherein a metal frame extending from the back of the communication equipment to the side face is arranged around the periphery of the metal shell; the metal shell is segmented and separated into a first metal shell, a second metal shell and a third metal shell; the feeding points are respectively positioned between the first metal shell and the second metal shell and between the second metal shell and the third metal shell; an antenna branch I arranged at the first metal shell and an antenna II arranged at the third metal shell are respectively connected with a radio-frequency signal source of a PCB (Printed Circuit Board) mainboard arranged on the second metal shell, and signals are correspondingly fed in the first metal shell and the third metal shell through the feeding points. With a three-section type full metal shell structure, the metal frame becomes a part of the antenna, the first metal shell and the third metal shell can be used as antennas at the same time, and the antenna device has the advantages of ultra-wide low-frequency band width and high-frequency band width.

Methods are provided for fabricating packaged chips, each packaged chip having a protective layer, e.g., a transparent lid, metallic enclosure layer, shield layer, etc., and methods are provided for manufacturing such protective layer to be incorporated into a packaged chip. Lidded chip structures, and assemblies are also provided which include lidded chips.

The invention provides a structure integrating the metallic housing with the antenna of an electronic device, wherein the electronic device comprises the metallic housing and an antenna structure. The antenna structure comprises an antenna body. At least one micro slit is arranged on the metallic housing and is formed by a micro slit. The at least one micro slit divides the metallic housing into at least metallic area connected with the antenna body to be used as the radiator of the antenna structure.

The present invention is to provide a connector having a metal separating plate being fastened by a tongue plate in integral formation, which is compatible to USB Type-C standard and includes a tongue plate made of plastic integrally and provided with a metal separating plate fixedly disposed therein; a plurality of first connection terminals respectively inserted into first connection slots formed in the tongue plate near a top surface of the metal separating plate; a plurality of second connection terminals respectively inserted into second connection slots formed in the tongue plate near a bottom surface of the metal separating plate; grounding boards having structures respectively matched with the tongue plate, so as to enclose an outer edge of the tongue plate; and a metal casing having a structure matching with the tongue plate, so as to allow the tongue plate and grounding boards to be assembled into the metal casing.

The invention can make separation for all kinds of components in wasted Li-ion battery such as: case, electrolyte, anode material, cathode material, adhesive, copper foil, and aluminum foil. The process includes: breaking wasted batteries by mechanical process; separating metal case from others; washing out electrolyte using organic solvent, and filtering it from remaining solid; processing the remaining component where the electrolytes are removed using organic solvent to make all electrode active component eluted from current collector, and separated from diaphragm, copper foil, and aluminum foil. The solvent and adhesive can be reused.

The dental implant system includes implants having integral abutments therewith for the removable or fixed attachment of plural or single prosthetic teeth, as appropriate. The system for removable dental prostheses includes a metal housing permanently installed in the removable prosthesis, and a rubber retentive insert installed in the housing. The insert is removably installed over the abutment of the implant to secure the dental prosthesis thereto. The system includes transfer copings for transferring an impression to the lab for manufacture of the prosthesis, and lab processing copings and analogs for handling and forming the prosthesis during manufacture. The system may be assembled as a kit having some or all of the above components.

Method for determining loading of a filter. The filter has a first dielectric constant. The filter becomes loaded with contaminant material that has a second dielectric constant. The filter, such as a diesel particulate filter, is contained within a metallic enclosure forming a microwave cavity. The method includes establishing microwave energy in the cavity and monitoring changes in the cavity microwave response, the changes being related to filter loading.

A waterproof electrical receptacle connector includes a plastic shell, a metallic shell, an insulated housing, and a buckling member. The plastic shell includes a shell body, a through hole defined in the shell body, and an assembling hole defined on the shell body. The metallic shell is received in the through hole and defines a receiving cavity. The insulated housing is received in the receiving cavity and includes a base portion and a tongue portion extending from the base portion. The buckling member is positioned with the assembling hole and includes a buckling body and a hook extending from the bottom of the buckling body and protruded out of the assembling hole. Accordingly, the hook is protruded out of the assembling hole and engaged with a buckling hole of a circuit board, so that the front of waterproof electrical receptacle connector can be firmly positioned with the circuit board.

A dental device, in particular a one-piece dental implant, comprising an outer body made of metal; and an inner body made of plastic or composite, wherein the inner body comprises a core perfectly fitting into a cavity of the outer body, and a method for manufacturing a dental device, in particular a one-piece dental implant, comprising the following steps in any order: manufacturing an outer body of metal; and manufacturing an inner body of plastic or composite material; wherein the inner body comprises a core manufactured within a cavity of the outer body.

A low-profile Universal-Serial-Bus (USB) connector includes a substantially flat base structure that is received in the lower section of a conventional female USB connector, and includes metal contacts formed on an upper surface of the base structure. Wobble or vertical play is reduced by rails extending along side edges of the base structure that are partially inserted into gaps formed between the metal case and base structure of the female USB connector. Between metal contacts on the low-profile USB connector are raised ribs (dividers) that prevent undesirable damage or contamination to the metal contacts. The connector base structure of the low-profile USB connector can be separate or can be integrated with a circuit board that holds a flash memory chip and a USB controller chip.

The invention relates to a novel highly-abrasion-resistant, anti-corrosion and anti-static coating and a preparation method thereof. The coating comprises basic thermosetting resin and a filler, wherein the basic thermosetting resin is modified resin for coatings; the filler is formed through blending and combining one or more of a carbon nano tube, carbon black, graphite, graphene, nano aluminum powder and conductive mica powder with one or more of quartz sand, glass flake, nano silicon dioxide, nano-molybdenum disulfide, aluminium oxide and modified montmorillonite. The coating is directly smeared or sprayed on the surface of a metal outer shell of electronic and electrical equipment, the equipment can be effectively prevented from being corroded by the environment for a long time, and the influence of pad points and electromagnetic interference on the safe, normal and stable use of the equipment is prevented.
