摘要:
An electroplating apparatus applies an electroplated coating to a female thread formed on a pipe end portion of a steel pipe. The apparatus includes an inner seal member, a capsule, a discharge outlet, an opening, a cylindrical insoluble anode, a plating solution supply tube, and a plurality of nozzles. The seal member divides the interior of the steel pipe at a location longitudinally inward of a region on which the female thread is formed. The capsule is attached to the pipe end portion. The outlet is designed to discharge a plating solution inside the capsule therefrom. The opening facilitates discharge of the solution inside the capsule. The anode is disposed in the inside of the pipe end portion. The supply tube projects from an end of the anode. The nozzles eject a plating solution between the outer surface of the anode and the inner surface of the pipe end portion.

摘要:
Provided are a cylinder plating apparatus and a cylinder plating method, in which the distance between an insoluble electrode and a cylinder to be processed can be kept constant regardless of the diameter of the cylinder to be processed, and the surface area of the insoluble electrode is increased to reduce the current density of the insoluble electrode, thereby being capable of reducing burden on the insoluble electrode. The cylinder plating apparatus is configured to plate an outer peripheral surface of the cylinder to be processed in such a manner that a pair of the insoluble electrodes each having a shape in which at least a lower part thereof is curved inward and being constructed such that at least the lower part has a comb-like portion are brought close to both side surfaces of the cylinder to be processed with predetermined intervals. The insoluble electrodes face each other in a staggered pattern so that projections of the comb-like portion of one of the insoluble electrodes are located at positions of recesses of the comb-like portion of another one of the insoluble electrodes. The insoluble electrode is configured to rotate about an upper end of the insoluble electrode so that the distance of closeness of the insoluble electrode to the outer peripheral surface of the cylinder to be processed is adjustable depending on the diameter of the cylinder to be processed.

摘要:
Nanofluidic passages such as nanochannels and nanopores are closed or opened in a controlled manner through the use of a feedback system. An oxide layer is grown or removed within a passage in the presence of an electrolyte until the passage reaches selected dimensions or is closed. The change in dimensions of the nanofluidic passage is measured during fabrication. The ionic current level through the passage can be used to determine passage dimensions. Fluid flow through an array of fluidic elements can be controlled by selective oxidation of fluidic passages between elements.

Durable seamless replication tools are disclosed for replication of seamless relief patterns in desired media, for example in optical recording or data storage media. Methods of making such durable replication tools are disclosed, including preparing a recording substrate on the inner surface of a support cylinder, recording and developing a relief pattern in the substrate, creating a durable negative relief replica of the pattern, extracting the resulting durable tool sleeve from a processing cell, and mounting the tool sleeve on a mounting fixture. Apparatus are disclosed for fabricating such seamless replication tools, including systems for recording a desired relief pattern on a photosensitive layer on an inner surface of a support cylinder. Also disclosed are electrodeposition cells for forming a durable tool sleeve having a desired relief pattern. The replication tool relief features may have critical dimensions down to the micron and nanometer regime.

An apparatus is disclosed for electroplating an inside wall of a transfer mold, the transfer mold being suitable for use in semiconductor device encapsulation. Specifically, the apparatus comprises a fixture, as well as a through-hole in the fixture for receiving an electrode to electroplate the inside wall of the transfer mold. In particular, the through-hole is configured to receive the electrode in a slide-fit to form a mutual interference fit for securing the electrode to the fixture. Upon fitting the electrode into the through-hole, the apparatus can then be used to electroplate the inside wall of the transfer mold by introducing the electrode into the space adjacent to the inside wall of the transfer mold. A device for use as an electrode in the apparatus is also disclosed.
