    摘要： A thin-film resistor comprising a mixture of rhodium (Rh) oxide as a resistive material, and at least one element M selected from the group consisting of silicon (Si), lead (Pb), bismuth (Bi), zirconium (Zr), barium (Ba), aluminium (Al), boron (B), tin (Sn), and titanium (Ti), wherein M/Rh, or the ratio of the number of element M atoms to that of rhodium (Rh) atoms is in the range of 0.3 to 3.0. Thin-film resistor is formed from the process of preparing a solution of an organometallic material, coating the material on a substrate, drying and then firing the material at a peak temperature not less than 500.degree. C.

    摘要： A body of a specially prepared, porous vitreous carbon which does not crack or substantially change in electrical resistance with time when heated to elevated temperatures in air and which is used in a method or apparatus to heat a fluid stream flowing in the pores of the body as a result of natural convection or pumping of the fluid is described. The body is composed of electrically conductive rigid, interconnected and multidirectional continuous strands of vitreous carbon forming a rigid porous, three dimensional skeletal structure. The body as an electrical resistance element has current conductive paths between at least two regions; is shaped to provide particular cross-sections along the conductive paths; and has electrical connector means attached at the regions of the body so that current can be distributed through the body. The electrical resistance element is particularly useful as a heating element for air flowing through the pores in electrically powered room space heaters, hair dryers, hand dryers and the like and can also function as a self-cooling resistor. In a like manner, electromagnetic energy is used to heat a body of the porous vitreous carbon so as to heat a fluid stream flowing through the pores.

    摘要： A BORO-CARBON COATING IS DEPOSITED UPON THE ELECTRICALLY HEATED SURFACE OF A PYUROLYTIC CARBON COATED FUSED SILICA OR QUARTZ FIBER AS IT IS PASSED THROUGH A LIQUID THERMALLY DECOMPOSABLE BORON COMPOUND SUCH AS BORON TRICHLORIDE DISSOLVED IN A NON-POLAR ORGANIC SOLVENT SUCH AS BENZENE. THE HEATED PORTION OF THE FILAMENT PRODUCES AN ENVELOPE OF SOLVENT VAPOR AND BORON TRICHLORIDE GAS WHICH ARE PYROLYTICALLY DECOMPOSED AND CARBON AND BORON SIMULTANEOUSLY DEPOSITED ON THE FILAMENT. THE DISCLOSED APPARATUS INCLUDES A MERCURY ELECTRODE STRUCTURE AND OTHER FEATURES BELIEVED TO BE NOVEL.
