Title: Cooling method of lance for blowing powder into blast furnace
Inventor: AKIMOTO EIJI
IPC: C21B7/00
Filed: 1984-12-26
Abstract: PURPOSE:To always maintain a lance in a sound state by feeding a cooling gas from a separately provided cooling gas piping for cooling the lance to the lance when the supply of a carrier gas to the lance of which the top end is projected into a blow pipe is interrupted. CONSTITUTION:High-temp. air for blasting is blown through the blow pipe 15 into a blast furnace 17 through a tuyere 16. The lance 1 attached to the pipe 15 is connected to a transport piping 2 having an on-off valve 8 and the cooling gas piping 7 having a check valve 6 and an on-off valve 7 in this case. The valve 8 is therefore closed immediately when the supply of the cooling gas of the piping 2 stops. On the other hand, the valve 7 of the cooling gas line is opened to supply the cooling gas (for example, air) to the lance 1. Accidents of the blow-off of the high-temp. gas from the inside of the furnace owing to damage of the lance and the downtime of the blast furnace for the purpose of exchanging the damaged lance are thus eliminated and life of the lance is extended.

Title: Method of detecting and correcting pulse noise of multifunctional remote control transmitter
Inventor: KEN JIYUNTON
IPC: H04Q9/14
Filed: 1991-10-25
Abstract: PURPOSE: To eliminate noise with only one input by re-analyzing an inputted signal for detecting and correcting the noise and inputting it again only with respect to an unrestorable noise. CONSTITUTION: In a noise decision circuit, a pulse value smaller than (the extent of delay)+α is decided to be as a noise because the value of an N-th pulse with Wn is equal to (the pulse width essentially inputted)+(the extent of delay). If Wn is smaller than (the extent of delay)+α, the pulse width Wn of the current turning-on period and a temporary stop pulse width Pn are added to a preceding temporary stop pulse width (Pn-1), so that the noise is ignored because of (the current pulse width Wn)=Pn=0. If Wn is larger than (the extent of delay)+α, Wn is compared with a set maximum value K. When Wn is larger than the set maximum value K, it is judged that an unrestorable waveform generated from a strong light noise has been inputted, and re-input of the pulse waveform is requested.

Title: Protecting circuit for exhaust gas sensor
Inventor: NOTO YASUO
IPC: G01K7/00
Filed: 1998-10-01
Abstract: PROBLEM TO BE SOLVED: To protect a sensor when an electronic circuit malfunctions by stopping a temperature detecting circuit when the output signal of the temperature detecting circuit is extended by the time longer than a predetermined time. SOLUTION: A signal, which operates the constant current circuit for detecting temperature, is inputted into a counter. When this value becomes the constant time or more, the constant current circuit (temperature detecting circuit) is forcibly stopped. When switches SW1 or SW2 continues the ON state, the current continues to flow. By this current, oxygen disappears from an oxygen-reference chamber by zirconia, or, since the oxygen migrates from the place, where oxygen is not resent, the trouble that the oxygen of the grid of zirconia migrates, occurs. For eliminating such troubles, the starting of SW1 and SW2 is driven by the signal of the circuit for outputting the prohibiting signal and the signal taking AND when the respective signals do not return within the specified time.  That is to say, when the signals of SW1 and SW2 become longer than the time determined by the time constant, the prohibiting signal becomes HIGH.
