Title: Operating method of blast furnace
Inventor: OGAWA AKINOBU
IPC: C21B5/00
Filed: 1982-01-14
Abstract: PURPOSE:To prevent channeling when it is liable to occur in the operation of a blast furnace by reducing the opening degree of a by-pass valve for a top pressure turbine in accordance with the opening degree of the valve of a top pressure controller so as to maintain top pressure equal to that during normal operation even in case of a small volume of fed air. CONSTITUTION:When conditions under which channeling is liable to occur are produced in the operation of a blast furnace, an auxiliary bypass valve is changed over from the fully opened state to a perfectly closed state at the time when a top pressure turbine is stopped. The opening degree of a main by-pass valve is then reduced suitably in accordance with the opening degree of the valve of a top pressure controller while reading it. Thus, a margin is provided to the opening degree of the valve of the controller, and high top pressure equal to that during normal operation is maintained even in case of a small volume of fed air to prevent channeling.

Title: Cr timer circuit
Inventor: UEDA YASUKIYO
IPC: H03K17/28
Filed: 1981-01-16
Abstract: PURPOSE:To prevent variation in timer time and time lag of restarting by completing the operation of a timer in a time which is an integral multiple by setting the constant charging time and constant discharging time of a capacitor to a pair. CONSTITUTION:When a switch 2 for starting a timer is closed, the middle-point potential V0 of a bridge is close to the voltage Vcc of a power source 1 and a storage device 11 is reset continuously. When the switch 2 is opened, the potential V0 drops according to charging characteristics once the storage device 11 is released from being reset and, when reaching a low potential VL, inverted to a high potential VH. Then, the storage device 11 is set and the discharge of a capacitor 3 starts; when the potential V0 reaches the high potential VH, the output of a gate 13 is held high, thus completing the operation of the timer. As the leakage current of the capacitor 3 increses, the charge completion time is extended, but the discharge completion time is shorten, so that an error in time copletion time is nearly eliminated.

Abstract: PROBLEM TO BE SOLVED: To provide a high/accuracy A/D converter by regulating the ratio of a capacitance between one terminal of a serial connector and a node and a capacitance between the other terminal of the serial connector and the node corresponding to at least one of first and second reference voltages. SOLUTION: The sum of the capacitances of MOS capacitors C2-1 and C2-2 connected in parallel is the 1-4 capacitance of an MOS capacitor C1 when the sum is measured while applying the same bias voltage. The capacitance of a serial connector 6B is regulated by the MOS capacitor C2-2. Besides, the capacitance of the MOS capacitor C2-1 is the 1/4 capacitance of the MOS capacitor C1 at the time of applying the voltage of a 15/16 reference voltage VREF to one electrode of the MOS capacitor C1. The MOS capacitor C2-2 is connected in parallel with the MOS capacitor C2-1 by switches S4 and S5 or disconnected from the MOS capacitor C2-1. Thus, an A/D converter 1B regulates the capacitance by selecting the connection/non-connection of one of two capacitors while using these MOS capacitors C2-1 and C2-2.
