Title: Method for controlling blowing in converter
Inventor: MIYAMOTO MASAKAZU
IPC: C21C5/30
Filed: 1995-01-12
Abstract: PURPOSE: To estimate the components and the temp. of molten steel at the time of stopping blowing in real time and to accurately control to a prescribed value by using a decarburizing speed factor and a temp. raising speed factor depending on the slag quantity in a control model of the conventional statistical technique at the time of refining molten steel in an oxygen blowing converter. CONSTITUTION: A molten slag quantity calculating equation is introduced in advance based on raw material molten iron and CaO, MgO and SiO2 quantities as flux charged into the converter from the past operational results. Successively, the molten slag quantity is estimated from molten iron information (the components, temp., and quantity of the molten iron) of the present operation and the operational results by using the molten slag quantity calculating equation during oxygen blowing operation, and the decarburizing speed factor and the temp. raising speed factor in an oxygen balance equation and a temp. balance equation of the oxygen blowing control model are fixed by using this estimated value.  The molten steel temp. and the necessary oxygen quantity required for bringing the molten steel components at the time of stopping the blowing into the target range with the oxygen balance equation and the temp. balance equation are estimated by using these both factors. Based on this value, the components and the temp. of the molten steel at the temp. of stopping the blowing are controlled in real time to be in the target values.

Title: Gain control circuit
Inventor: MOCHIZUKI MASAAKI
IPC: H04N5/53
Filed: 1983-01-12
Abstract: PURPOSE:To eliminate the factors of distortions such as sags, etc. by using a gain control circuit which amplifies the video signal of a TV receiver to control the potential given a capacitor which controls an amplifier circuit with the control given to its charging/discharging in response to the amplifying signal with a gate pulse signal. CONSTITUTION:The gain of an amplifier circuit part 2 of a TV receiver is controlled with application of a control signal to a gain control terminal 10. A reference voltage source 30 is connected to the base of a transistor (TR)28, and the pulse given from a gate pulse impressing terminal 31 is applied to the base of a TR29. Therefore the TR29 conducts only of a pulse period, and a charging/ discharging current is supplied to a capacitor C9. When a video signal containing a synchronizing signal of negative polarity emerges at an output terminal 3, a TR13 is cut off with conduction of a TR14 respectively. Then a TR16 is cut off or a TR17 conducts. In this case, the TR29 does not conduct as long as no gate pulse exists and therefore the potential of the capacitor C9 has no change. Thus it is possible to eliminate the factors of distortions such as sags, etc. and the response performance is improved.
