Method and structure for waterproofing a terminal splice

To decrease cap diameter covering a terminal splice and improve workability and waterproof performance, a stopper is inserted in one opening of a heat shrinkable tube. The heat shrinkable tube is heat-shrunk in this state, then a cap having end an closure is formed. A fluid thermosetting waterproofing agent is injected into the cap from a second opening. A thermal splice, which is formed from welded strands stripped from a plurality of wire terminals, is inserted and immersed in the thermosetting waterproofing agent. Then, the entire cap is heated and heat-shrunk at a predetermined temperature and the thermosetting waterproofing agent is heat-hardened.

Multi-function composition for settable composite materials and methods of making the composition

A multi-function composition for incorporation into settable composite materials is provided. The composition is formulated as an additive to modify the density of the composite material and increase the rate of hardening or strength development of the material. The composition of the additive generally includes an alkaline activation compound such as sodium silicate and a modified low density siliceous material having at least one region morphologically altered by a chemical, such as a partially digested region. The additive can be in slurry form, in powder form, or in an agglomerated particle form. The additive can be produced using a two-stage process in which a siliceous material is reduced in particle size, combined with an alkali compound in a solution and then digested in an atmospheric or pressurized vessel. In some implementations, the solution can be spray dried to form agglomerated particles containing the alkaline activation compound and the low density siliceous particle having one or more partially digested regions.

Halogen-resistant, anodized aluminum for use in semiconductor processing apparatus

We have discovered that the formation of particulate inclusions at the surface of an aluminum alloy article, which inclusions interfere with a smooth transition from the alloy surface to an overlying aluminum oxide protective film can be controlled by maintaining the content of mobile impurities within a specific range and controlling the particulate size and distribution of the mobile impurities and compounds thereof; by heat-treating the aluminum alloy at a temperature less than about 330° C.; and by creating the aluminum oxide protective film by employing a particular electrolytic process. When these factors are taken into consideration, an improved aluminum oxide protective film is obtained.

Method of controlling hardening with laser beam and laser beam hardening device

A workpiece is irradiated by a laser beam scanned in an oscillating track as the workpiece is advanced along a feed path in a hardening process. Sinusoidal variations in scan velocity are offset by decreasing the laser beam power level at phases in the scanning cycles corresponding to high and low scan displacement peaks, where the scan velocity is least. The beam power is increased near the scanning center line where the scan velocity is highest. The beam energy applied per unit of area is thus equalized over the scanning cycle. The workpiece temperature can be sampled at regular phases by a non-contact temperature sensor in the optical path, and used to control beam power versus phase in a subsequent scanning cycle. Alternatively or in addition, a sinusoidal beam power pattern can be stored and used to offset scan velocity variations as a function of phase.
