摘要:
A process of producing an article having a surface provided with an optical diffraction grating such that the surface generates visible color when illuminated with diffuse white light. The process involves deforming a starting material to produce the article having the surface and, during the deforming step, impressing a diffraction relief pattern on the surface by a tool provided with a bearing surface having a corresponding surface relief pattern of parallel lines that contacts the surface of the article under pressure. While the diffraction relief patter is being impressed, the surface is caused to slide in a direction of movement relative to the bearing surface of the tool. The invention also relates to the article.

The invention provides a method of manufacturing a metal foil for an electrolytic capacitor. In the case of slitting a wide metal strip subjected to etching treatment into a predetermined size with a cutting blade, a slitting portion of the heated wide metal strip is slit to provide the metal foil with few burrs and cracks at the slit edge surface.
摘要:
Metal strip is produced by feeding a cutting tool continuously into the peripheral surface of a rotating cylindrical metal workpiece and coiling the peeled strip continuously around a coiler drum. The strip is initially coiled by means of a clamp connected by a flexible linkage to the coiler drum which grips the leading edge of the strip to pull it around the periphery of the drum.

This invention relates to a process for making metal wire, comprising: (A) forming metal foil; (B) cutting said foil to form at least one strand of metal wire; and (C) shaping said strand of wire to provide said strand with desired cross-sectional shape and size. This process is particularly suitable for making copper wire, especially copper wire having a very thin diameter (e.g., about 0.0002 to about 0.02 inch).
摘要:
The present invention relates to a system for monitoring tension of a peeled strip during threading of the strip onto a coil wrapping assembly. Sensors mounted on the coiler assembly monitor strip tension during threading such that a break in the strip triggers shutdown of the machine including withdrawal of the cutting tool from the billet to prevent damage to the tool.
