摘要:
An electrode is disclosed for use in MIG/MAG welding. The electrode comprises an elongated electrode body within which is embedded a metallic filament. In some embodiments, the filament is copper, and is offset from the center of the electrode body. A method is disclosed for forming an electrode. The method may include removing oxidation from a surface of an electrode body, forming the electrode body to a desired size and geometry, removing lubricants from the surface of the electrode body, forming an elongated channel in a surface of the electrode body, depositing a filament in the elongated channel, and forming the electrode body over the filament. Other embodiments are disclosed and claimed.
摘要:
A system, in certain embodiments, has a composite seal with both a metal shell and an elastic core, such as an elastomer core. In one embodiment, the composite seal has an annular metal shell with a top, a bottom, and a seal interface disposed between the top and the bottom. The composite seal also has an elastomer disposed within the annular metal shell, wherein the elastomer is configured to impart pressure against the seal interface.

Methods for forming an insert, such as a threaded or threadable insert, within a cavity in an implant, such as a spinal spacer. In some implementations, an implant body comprising a first, non-threadable, may be provided. A cavity may be formed in the implant body, after which an insert may be positioned within the cavity. Preferably, the insert comprises a second material distinct from the first material, wherein the second material has physical properties distinct from the first material. A female thread may then be formed within the insert, which may allow for threading an otherwise unthreadable, or relatively unthreadable, material.
摘要:
Systems and methods for forming an insert, such as a threaded or threadable insert, within a cavity in an implant, such as a spinal spacer. According to various embodiments, a spinal interbody spacer may include a proximal end and a distal end. The interbody spacer may be manufactured using a non-threadable material, or at least a material that is difficult to thread, such as a ceramic, a glass, or a porous material. Some embodiments may comprise a silicon nitride ceramic material. A cavity may be formed in the interbody spacer, such as in the proximal end. A material having desired properties lacking in the spacer, such as a threadable insert within a non-threadable spacer, may be inserted into the cavity. The threadable material may then be threaded in order to form a female-threaded insert within the otherwise non-threadable interbody spacer.

A light measuring arrangement maintains the initial filtering function of an optical filter having a dye dispersed therein. The light measuring arrangement includes a measuring unit configured to measure an intensity of light emitted from a measurement target at a predetermined wavelength. The light measuring arrangement also includes the optical filter unit having the dye. The light measuring arrangement also includes a dye diffusion restricting unit configured to restrict diffusion of the dye from the optical filter unit. The optical filter unit constitutes part of an optical path for the light traveling from the measurement target to the light measuring unit.

A method of manufacturing a protection frame used in a miniature microphone is provided. In one embodiment, the method comprises the steps of: (1) preparing a substrate made of an insulating material with a prescribed thickness and a prescribed area; (2) forming a plurality of holes at prescribed intervals on the substrate; (3) forming a first metal shielding layer on the inner surface of each of the plurality of holes formed on the substrate; (4) filling an insulating material in the plurality of holes; (5) forming a plurality of extended portions on the surfaces of both sides of the substrate, each extended portion covering a part of the end face of the insulating material and the whole end face of the first metal shielding layer of a hole; (6) forming a cavity in each insulating material-filled hole, the caliber of each cavity being slightly smaller than the inner caliber of the corresponding extended portion formed in the above mentioned step (5); and (7) cutting the plurality of holes from the substrate to produce a collection of protection frames.
