  • Patent number: 4307442
    Abstract: A transmission line interconnecting system including an AC-DC converter connected to a first transmission line; and a forced-commutated type inverter connected to a second transmission line. DC terminals of the AC-DC converters and the forced commutated type inverter are connected and the output voltage of the forced commutated type inverter is varied by controlling DC voltage to feed a reactive power to the second transmission line in a normal state and to feed an active power from the first transmission line through the AC-DC converter and the forced excited type inverter to the second transmission line in an emergency state.

  • Patent number: 4027728
    Abstract: A semiconductor device is immersed into a cooling medium in its liquid phase disposed in a vessel. The cooling medium changes to its vapor phase due to heat from the semiconductor device to enter a condenser located above the vessel. The cooling medium condensed in the condenser passes through a conduit connected to the lower portion of the vessel to be directly mixed with the liquid cooling medium within the vessel.
