Abstract: A phase change optical recording medium includes a phase change optical recording layer which transits between two states of the crystalline state and the amorphous state when irradiated with light, and a heat adjustment layer which is formed adjacent to the phase change optical recording layer and abruptly increases or decreases thermal conductivity with increasing temperature upon irradiation of recording light. This phase change optical recording medium can decrease the size of the recording mark and makes high-density recording possible.

Abstract: Applications of a metallized textile. The textile is activated by precipitating noble metal nucleation sites on the fibers of the textile. Immersing the activated textile in a suitably prepared solution of a metal cation, and adding a reducing agent, leads to the formation of a metal plating tightly and intimately bonded to the fibers of the textile. Exposure of the metallized textile to air oxidizes the surface of the metal plating. Applications of the metallized textile include acaricides, fungicides, bactericides, armor, electrodes, anti-static devices, RF shielding, and radar reflectors.

Abstract: There is provided an integrated semiconductor processing apparatus which produces less dust. The apparatus comprises a reaction chamber, a boat means, a motor, and a sealing mechanism. The sealing mechanism includes a movable sealing means which serves as a non-contact seal when a wafer is being rotated and which serves as a contact seal when the wafer is static.

By increasing the pressure inside the expandable elastic seal, the surface of the elastic seal is put in contact with a rotating shaft to achieve perfect sealing. The internal pressure of the expandable elastic seal can be adjusted to control the contact and non-contact state of the seal. The apparatus according to the invention suppresses generation of dust in all steps of etching to improve production yield.

Abstract: Solutions of intermediate molecular weight polymers from about 200,000 to about 4,000,000, such as polyethylene, in a relatively non-volatile solvent are extruded through an aperature at constant concentration and thereafter stretched at a ratio of at least about 3:1 prior to cooling to form a first gel. The first gels are extracted with a volatile solvent to form a second gel, and the second gel is dried to form a low porosity xerogel. Stretching occurs with any one or more of the first gel, second gel or xerogel. The polyethylene products produced by our process include products having a molecular weight between about 200,000 and about 4,000,000 a tenacity of at least about 13 grams/denier, a modulus of at least about 350 gram/denier, a porosity of less than 10% by volume, a crystalline orientation function of at least about 0.95, and a main melting temperature of at least about 140.degree.

Abstract: In one general aspect, the invention involves applying a chemical treatment to fibers, such as reinforcing fibers suitable for making a composite article, so as to size and/or preimpregnate the fibers. The chemical treatment has a relatively low viscosity and is substantially solvent-free and non-radiation curable. Heat energy may be employed to lower the viscosity and improve the wetting ability of the applied treatment and/or to increase the molecular weight of, or otherwise cure, the treatment with essentially no generation of solvent vapor. The treated fibers are used to form a composite strand, which may be subsequently processed in-line or off-line into a composite article having fibers disposed in a polymeric matrix. Another general aspect relates to encased composite strands, in thread or pellet form, and to wire-coating methods and apparatus for making them. The strands are moldable into fiber-reinforced thermoplastic composite articles.
