  • Patent number: 6384705
    Abstract: A miniaturized common mode EMI filter with a greatly simplified design so that it can be manufactured very economically. The common mode filter includes: (a) a magnetic main body; (b) a pair of substantially identical electrically conductive planar coils embedded in the magnetic main body; and (c) an insulative planar coil sandwiched between the pair of electrically conductive planar coils, wherein the insulative planar coil has a pattern that is substantially identical to and inclusive of the pattern of the electrically conductive planar coils so as to insulate the pair of electrically conductive planar coil from each other. The common mode filter retains low normal mode impedance and high common mode impedance, with a substantially reduced physical size, so that it can cost-effectively maintain a high fidelity of the normal mode waveform of signals for electronic devices that utilize differential transmission technology and keep the common mode EMI noise to a minimum.

  • Patent number: 6008436
    Abstract: Nematode-resistant transgenic plants are disclosed. The plants comprise plant cells containing a DNA construct comprising a transcription cassette, which construct comprises, in the 5' to 3' direction, a promoter operable in the plant cells, and a DNA comprising at least a portion of a DNA sequence encoding a nematode-inducible transmembrane pore protein in either the sense or antisense orientation. Intermediates for producing the same along with methods of making and using the same are also disclosed. In an alternate embodiment of the invention, the sense or antisense DNA is replaced with a DNA encoding an enzymatic RNA molecule directed against the mRNA transcript of a DNA sequence encoding a nematode-inducible transmembrane pore protein.

  • Patent number: 5921664
    Abstract: A reading lamp has a base seat, a hollow casing disposed on the base seat, a link device disposed between the base seat and the hollow casing, a lamp disposed between the base seat and the hollow casing, a button disposed on the hollow casing, a transparent plate disposed in the hollow casing, and a cover disposed on the hollow casing covering the transparent plate. The cover has a mirror reflecting a light from a bulb to a book while the cover is opened.

  • Patent number: 5837876
    Abstract: An isolated DNA molecule which comprises a DNA promoter sequence which directs root cortex specific transcription of a downstream heterologous DNA segment in a plant cell. A DNA construct which comprises an expression cassette comprising, in the 5' to 3' direction, a promoter of the present invention and a heterologous DNA segment positioned downstream from the promoter and operatively associated therewith. Transformed plants, such as tobacco plants, comprise transformed plant cells containing a heterologous DNA construct comprising an expression cassette as described above.

  • Patent number: 5096732
    Abstract: A fat-reduced, edible, water-in-oil spread is produced by heating a fat which is normally solid at room temperature so as to melt a substantial proportion of less thermally stable crystals in the fat; homogeneously admixing sufficient water to the heated fat to reduce the proportion of fat in the resulting admixture; cooling the admixture to crystallize a substantial proportion of the uncrystallized fat and produce a pumpable plastic mass; and subjecting the pumpable plastic mass to cutting and mixing in a turbine-like comminuting device while limiting the temperature rise of the plastic mass.
