Title: Superconductive current safety breaker
Inventor: SASAGAWA YOJI
IPC: H01H3/00
Filed: 1987-10-06
Abstract: PURPOSE:To make it possible to cut off a current at an appropriate time with respect to changes in the current flowing through or in temperature or magnetic field applied to a superconductive wire used in a circuit by attaching a ferromagnetic body to a movable contact point of a superconductive material and arranging a magnet in the direction of movement of the movable contact point. CONSTITUTION:A superconductive movable contact point 3 is constituted with a superconductive material of the same characteristic with that of a superconductive wire 4. If a critical current becomes smaller than a flowing current due to changes in the temperature or magnetic field surrounding the superconductive material, the superconductive wire 4 and the superconductive movable contact point 3 shift to normal conductors. While the superconductive movable contact point 3 has been repulsing a magnet 1 under the superconductive condition due to the Meissner effect, when the repulsive force is lost due to the breakage of the superconductive condition, the superconductive movable contact point 3 separates from the super conductive wire 4 caused by the force attracting an iron piece 2 attached to the contact point 3 and becomes in a condition of break. This makes it possible to cut off a current at an appropriate time with respect to changes in the current flowing through or in temperature or magnetic field applied to the superconductive wire 4.

Title: Method for operating blow-down in blast furnace
Inventor: KIMURA KAZUO
IPC: C21B5/00
Filed: 1987-10-08
Abstract: PURPOSE:To execute smooth discharge of residual pig iron in a short time by charging manganese ore in place of iron ore at the end period of blow down and generating and solidifying FeMn pig at hearth part. CONSTITUTION:In the blast furnace having e.g. 3,000m<3> inner vol., after starting reduced blast, the operation shifting to the FeMn pig is executed and charge of the ore is stopped at the time of becoming >=50% Mn in FeMn pig and the blow-down in the empty furnace is executed by replacing into coke. By this method, as the solidified FeMn pig is very brittle the residual pig iron can be easily crushed and discharged after blow-down operation. By this method, breaking and discharging treatment, which usually takes more than 10 days, can be shortened to about 1/3 of the days usually needed. Further, as the dis charged FeMn pig is supplied as sub-raw material for steel making, the effect of the steel refining at low cost can be obtd. as well.

Title: Method and apparatus for control of transmission for radio local area network station
Inventor: BURUUSU TABU TATSUCHI
IPC: H04J13/00
Filed: 1991-09-05
Abstract: PURPOSE: To obtain a local area network station which realizes high local area network(LAN) performance. CONSTITUTION: In a station 12 for a radio local area network, a threshold level circuit 62 includes a register that stores threshold. A station receiver 42 supervises a communication channel and gives a receiving level signal that represents a receiving signal level. The transmission of a data frame through a station transmitter 46 is allowed or delayed as the receiving level signal threshold might be above or below the threshold level although it does not matter whether or not a receiving signal is sent by a station in a local area network of a receiving station itself. The threshold is surely and dynamically updated when the station 12 receives a data frame from a LAN of its own. In this way, the use of a radio communication channel is improved.
