IPC: C21C5/46
Filed: 1993-09-29
Abstract: PURPOSE:To more accurately control molten steel temp. by more accurately predicting the temp. dropping amt. of the molten steel in the steelmaking process and reflecting the predicted value of the molten steel temp. on the blowing control in a steelmaking furnace. CONSTITUTION:Each amt. of the temp. drop of the molten steel caused by operational variable factors is obtd. on the basis of the actual data in the past heats. The temp. drop amt. DELTAT of the molten steel from the time t2 of completing the treatment in the steel-making furnace to the time t3 of starting the casting is predicted from the temp. drop amt. of the molten steel caused by operational variable factors. The temp. Ta at the time t2 of completing the steelmaking furnace treatment is obtd. from this temp. drop amt. DELTAT and the temp. Tb at the time of starting the casting to decide the time t1 of starting the steelmaking furnace treatment, and this temp. Ta at the time of completing the steelmaking furnace treatment is used as the aimed temp. to execute the automatic blowing control of the steelmaking furnace. By this method, the temp. drop amt. of the molten steel can accurately be predicted and the automatic blowing control is executed with good accuracy, and the variance of the molten steel for each heat can be eliminated.

Title: Torque detecting device
Inventor: AZUMA KENICHI
IPC: G01L25/00
Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To acquire precisely an abnormal signal outputted from a signal processing circuit, and execute smoothly interruption control for a control operation of an EPS(electrically-driven power steering) controller. SOLUTION: A sensor circuit signal Sa is taken out as a measuring signal Sc through filters 17, 19, and existence of the oscillation state is confirmed by a signal monitoring circuit part 22. If oscillation is generated, the output value of a torque detection signal St is attenuated gradually toward a neutral potential by a control circuit part 23, and finally a high-level or low-level abnormal generated signal is outputted toward an EPS controller, to thereby stop power assist control on the EPS controller side. As torque energization is reduced gradually, a control operation of the EPS controller can be interrupted without a sense of incompatibility in a steering operation.

Abstract: PROBLEM TO BE SOLVED: To reduce the number of bit lines, prevent generation of an irregular current by a random data to avoid irregular operation and failure by using in common the bit lines of the adjacent columns in the same row and selecting the adjacent columns with different word lines. SOLUTION: In the same row, memory cells M1 to M4 are arranged, bit lines (BL) 1 and 2 are arranged to the cell M1, while BL2 and BL3 to the cell M2, BL3 and BL4 to the cell M3, BL4 and BL5 to the cell M3 and BL4 and BL5 to the cell M4. Namely, one BL is used in common between the memory cells of the adjacent odd and even number columns and two word lines (WL) are wire per row address. Since the cells M1, M3 of the odd number columns are connected to WL1, while the cells M2, M4 of the even number columns are connected to WL2, only the N+1 BLs per N columns are enough. Thereby, the number of BL can be reduced and generation of irregular current due to the random data when the power is turned ON can be prevented in order to prevent irregular operation and breakdown.
