  • Patent number: 6720677
    Abstract: Power lines include three or more conductors for transmitting alternating currents. The conductors are arranged in one combination of the conductor arrangement so that the sum of phase differences between the currents flowing through adjacent conductors is maximum, and if there exists a plurality of such combinations, the one combination is selected in which the value of the smallest one of the phase differences between the currents flowing through every adjacent conductor is largest. With this arrangement, power loss is reduced.

  • Patent number: 6655789
    Abstract: An ink jet print head comprises a substrate formed with a heating resistor, an ink path defining member for defining an ink supply path, and a orifice plate, and in the orifice plate, there is formed an ink outlet at the position opposing the heating resistor. Further, a heating zone surrounding the heating resistor is formed at the position corresponding to the heating resistor of the ink supply path. The channel resistance of the ink supply path is set so that a relationship is established between a quantity q of the discharged ink drop, a sectional area A of the ink outlet, and a maximal projection h that a meniscus of the ink has when it projects from the ink outlet after it has restored the exit level from a retreat position it had after the drop of the ink had been discharged, such that 0<h<0.3 q/A. Consequently, there is obtained a high-speed printing of high quality without dispersion.

  • Patent number: 6585532
    Abstract: A coaxial connector includes an upper insulating case provided with columnar ribs in the four corners thereof. These ribs are provided to position a fixed terminal and a movable terminal. The tops of the ribs are arranged so that the fixed terminal is easily guided. Half-circular concavities are formed on both of the sides of the fixed terminal. The concavities are fitted onto the ribs of the upper insulating case, so that the fixed terminal can be incorporated into the upper insulating case with a high positional accuracy. Thereafter, the ribs are thermally deformed into a dome shape by a welder, so that the fixed terminal is fixed to the upper insulating case.
