Title: Expansion type parabolic antenna
Inventor: MASUYAMA MASAYUKI
IPC: H01Q15/14
Filed: 1990-10-24
Abstract: PURPOSE:To simplify the mechanism keeping a mirror surface without making the expansion mechanism complicated by devising the antenna such that an expansion arm is expanded by an expansion force of an expansion boom and a mirror surface mesh is restricted by the expansion arm deformed elastically and plural hoops. CONSTITUTION:The restriction of an expansion arm 2 is released by a command from ground and then the restriction of an expansion boom 6. The expansion boom 6 able to be expanded thereby obtains an expansion force by filling a gas into an air bug and is expanded, the expansion force is delivered to the expansion 2 via an expansion wire 9, and the expansion boom 6 and the expansion arm 2 start expansion. The rotation of the arm 2 is locked in the state of the end of expansion, the arm 2 is deformed elastically in this state to be a mirror surface form, a mirror surface mesh 4 supported by the arm 2 and the hoop 3 keeps the mirror surface face without provision of a complicated mirror surface maintenance mechanism. Thus, the mechanism is simplified.

Title: Insulation monitor for dc arc furnace
Inventor: TAKAHASHI MAKOTO
IPC: F27B3/28
Filed: 1990-10-29
Abstract: PURPOSE:To always monitor an insulation resistance between a furnace bottom electrode of impurity deposited on a hearth and a furnace shell and to prevent damage of the shell due to a spark by disposing an impedance detecting conductor on an insulating plate of the electrode, and respectively coupling the conductor, the electrode and the shell to insulation monitors via leads. CONSTITUTION:If insulators 7 disposed on the circumference of a furnace bottom electrode 6 of impurity such as lead, etc., deposited on a hearth 2 are not normally operated and the electric conduction of the electrode 6 to metal 14 to be melted is not sufficient, a DC current flows in a circuit of the electrode 6, the insulator 7, a furnace shell 3, a furnace wall 4, the metal 14, an arc 13 and an upper electrode 8 (16 as shown), a spark is generated on the insulator 7, and the shell is damaged. The electrode 6 and the shell 3 disposed at both sides of the insulator 7 disposed on the circumference of the electrode 6 are connected to insulation monitors 8 via leads 17. Accordingly, if insulation resistance through the insulator 7 is reduced due to the impurity such as lead, etc., a decrease in the resistance value between the electrode 6 and the shell 3 is detected by the monitor 18. If the insulation resistance becomes a predetermined set value or lower, an abnormal signal is generated from the monitor 18, the operation of a DC arc furnace is automatically interrupted to prevent damage of the shell due to the spark.
