A high visibility light reflective golf ball is provided. The golf ball has light reflective material on the surface of the resin cover. The reflective material is fashioned as particles from aluminized polyester, aluminum foil, Metalflake.COPYRGT. Paint, or holographic film. In the preferred embodiment the material is incorporated into a clear coat applied to the cover. In alternative embodiments, the material is incorporated in or on the resin cover or in a paint applied to the resin cover and then protected with a clear finish coat. The percentage of surface of the ball covered with the reflective material may vary, preferablly in a range of 5% to 75% of the surface area, depending upon the light reflective properties desired.

A method of making an optical waveguide fiber with a fatigue resistant TiO.sub.2 -SiO.sub.2 outer cladding, and a substantially glass blank for drawing into such fiber, wherein a glass soot TiO.sub.2 -SiO.sub.2 outermost layer, with an initial TiO.sub.2 concentration greater than 10.5 wt. %, is deposited on a preform, and the preform is exposed to an atmosphere of chlorine and oxygen at a high temperature, and the resulting TiO.sub.2 concentration in the outermost layer of the TiO.sub.2 -SiO.sub.2 outer cladding of the substantially glass blank is less than the initial TiO.sub.2 concentration. In the glass blank form, the outermost layer includes a substantial volume percentage of crystalline phases and in the fiber form, the outermost layer includes inhomogeneities.

The present invention provides a surgical cutting instrument having a blade portion and cutting edge therefor with electric input elements located near the cutting edge for cutting the tissue and cauterizing the surfaces of the incision, thereby allowing surgery to be more rapidly performed. This is accomplished in accordance with the illustrated embodiments of this invention by providing electrodes of opposed polarity, applied to the blade, near the cutting edge. With an electrical potential applied, no current will flow between the electrodes and no heat is produced unless the electrode gap is bridged by a conducting medium such as a high conductivity physiological liquid from the incision. Heat is then generated by electric discharge below an arcing threshold in all areas where the blade is in contact with moist tissue. No electric discharge or heat occurs elsewhere. Moreover, if movement of the blade is halted, heat generation will automatically diminish as the cut tissue becomes dry as a result of cauterization.

This invention is related to the production of glasses having compositions within the copper and/or silver-halide-phosphate field, wherein at least one halide is present selected from the group of fluoride, chloride, bromide, and iodide, such glasses exhibiting softening points below about 400.degree. C., coefficients of thermal expansion (25.degree.-300.degree. C.) in excess of about 180.times.10.sup.-7 /.degree.C., high electrical conductivity, and electrochromic behavior. The copper-containing glasses may also demonstrate thermochromic properties.

A process for forming a solid tantalum capacitor is disclosed wherein the cathode is manganese dioxide formed by pyrolysis. The pyrolysis is performed in a nitrogen dioxide containing atmosphere at a temperature of between about 170.degree. C. and 250.degree. C., the nitrogen dioxide containing atmosphere comprising at least about 10% by volume of nitrogen dioxide, the remainder of said atmosphere being water vapor and gas inert in the pyrolysis process.

A method of anodizing porous tantalum material suitable for making a porous tantalum capacitor pellet or slug having decreased current leakage is described. After a pellet is anodized at a maximum predetermined desired voltage, it is removed from the anodizing bath and heated to a temperature of between 150.degree. C. and 300.degree. C. The pellet is maintained at such temperature for at least three minutes and then returned to the anodizing bath, at least once, and subjected to more electrical current.

A method of increasing the coercivity of a magnetic device having a magnetite film reduced from alpha ferric oxide. The alpha ferric oxide film is reduced to magnetite by subjecting it to a temperature greater than 400.degree. C in a reducing atmosphere. The temperature of the film is then changed to between about 150.degree. and 300.degree. C, and the reducing atmosphere is replaced by an oxidizing atmosphere. The film is subjected to the oxidizing atmosphere while the temperature is held between 150.degree. and 300.degree. C, thus causing the magnetite film to become partially oxidized to form a solid solution of magnetite and gamma ferric oxide as represented by the formula, (1-x)Fe.sub.3 O.sub.4 .sup.. xFe.sub.2 O.sub.3, where x is between 0.49 and 0.85.

Method of increasing the coercivity of magnetite films

A method of improving the magnetic properties of cobalt substituted magnetite by magnetizing the material to the saturation level in the desired direction, and then removing the magnetizing field. The material will retain a level of magnetization normally referred to as the remanent state of magnetization or simply remanence. The magnetized material is then subjected to a heat treatment to anneal the material. The above process significantly improves coercivity, hysteresis loop squareness ratio, and resistance to remanence loss due to external forces.
