Title: Reference voltage generation circuit
Inventor: AOKI YUKIO
IPC: G05F3/24
Filed: 1988-07-26
Abstract: PURPOSE:To obtain a constant reference voltage in spite of the fluctuation of a source voltage VDD by connecting a P-channel transistor in series to an N-channel transistor, and obtaining the reference voltage from the connecting point of serial connection. CONSTITUTION:The title circuit is provided with a diode D2 provided between a prescribed terminal 5 and prescribed potential Vss, and a P-channel MIS type transistor M1 connected between the prescribed terminal 5 and the power source VDD. When a power source level is set within a level not to operate the diode D2, a voltage Vref outputted from the prescribed terminal 5 is controlled by the P-channel MIS type transistor M1. Also, when the power source level is set within the level to operate the diode D2, the voltage Vref decided by relation between the P-channel MIS type transistor M1 and the diode D2 is outputted to the prescribed terminal 5. In such a way, it is possible to always obtain a stable reference voltage even when the fluctuation is generated in the source voltage VDD.

Title: Method for predicting volume of produced gas in coke oven
Inventor: SACHI TAKAFUMI
IPC: C10B57/00
Filed: 1992-06-19
Abstract: PURPOSE:To accurately predict the volume of produced gases in changing an interval for block units in coke pushing operation of a coke oven according to a specific method. CONSTITUTION:The fluctuation in volume of produced gases with the elapse of time during a period from charging of coal to discharging of coke in respective carbonization chambers of a coke oven battery composed of the many carbonization chambers is initially computed and estimated from the amount of the charged coal, coal volatile content, holding time and dry distillation time. The fluctuation in the average volume of the produced gases with the elapse of time for each pushed block is then computed from the estimated fluctuation in the produced gases with time to predict the volume of the produced gases in the coke oven battery. The fluctuation in the volume of the produced gases may be computed from the amount of the charged coal and the coal volatile content by utilizing the phenomenon that the volume of the produced gases is proportional to the volatile content and the amount of the charged coal regardless of the dry distillation time. When the holding time fluctuates from the reference value (HA) to (HB) the computation from the holding time is preferably carried out by horizontally displacing the timing of the volume of the produced gases in proportion to the time of only carbonization.
