Title: Method for continuously casting steel
Inventor: IDOKAWA SATOSHI
IPC: B22D11/04
Filed: 1995-02-28
Abstract: PURPOSE: To extremely reduce the entrapment of inclusion and gas bubble, etc., caused by molten steel spouted flow by arranging an AC superconducting magnet to the back surface of a mold, impressing shifting magnetic field and executing the flowing control of molten steel. CONSTITUTION: The molten steel M is poured into the mold 2 from an immersion nozzle 3. The AC superconducting magnet 1 is arranged to the back surface of the mold 2 to execute the flowing control of molten steel M. Since the electro-magnet is made to use the superconducting magnet 1, the intensity of the magnetic field can drastically be improved. The electromagnetic force F generated by impressing the shifting magnetic field is F= σ.B<2> .τ.f, and wherein, σis electric conductivity of the molten steel, B is magnetic flux density, τ is the pitch of poles and (f) is the frequency of advancing magnetic field. When the magnetic flux density B becomes 10 times, the electro-magnetic force F becomes 100 times. Since the damping of the magnetic field is developed through the mold 2, the frequency (f) of an electric source is made to be 1-10Hz.  The intensive electromagnetic force F can be acted to the spouted flow of the molten steel M from the immersion nozzle 3. A cast slab having good quality can stably be supplied.

Title: Power amplifier
Inventor: HIKITA JIYUNICHI
IPC: H03F3/21
Filed: 1983-03-10
Abstract: PURPOSE:To reduce an idle current produced at the time of non-signal by supplying signals via a resistance which is connected between the base of an output transistor and the base of a current positive feedback transistor. CONSTITUTION:The signal supplied through an input terminal IN is applied to the base of an output transistor TR4 of an OTL circuit 1' via an input TR1 and a current positive feedback detecting resistance R1. At the same time, the R1 is connected to the base of a TR3 of a current positive feedback circuit 2'. In such a way, the voltage corresponding to the signal current is impressed to the base of the TR3 by the R1. Thus it is possible to reduce an idle current at the time of non-signal by setting the resistance value of a current limiting resistance RO is set at a high level.
