Title: Air-fuel ratio control method for multi-kind fuel internal combustion engine
Inventor: NAKAJIMA TOYOHEI
IPC: F02D41/14
Filed: 1986-06-16
Abstract: PURPOSE:To permit a ternary catalyst to maintain its purifying function, by changing the control constant of proportional control or integral control in a feedback control, so that air-fuel ratio comes to be slightly in a rich side from the theoretical air-fuel ratio, and correcting a decrease of CO amount in accordance with the alcohol content in fuel. CONSTITUTION:An electronic control unit 4 arithmetically controls the valve opening time of an injector 36 on the basis of detection values of an O2 sensor 1, throttle valve opening sensor 31, intake absolute pressure sensor 32, water temperature sensor 33, intake temperature sensor 34 and a crank angle sensor 35 or the like. When the O2 sensor 1 finishes its activation, this time feedback correction coefficient is obtained from the preceding time correction value and feedback correction coefficient based on an O2 sensor output obtained by a PID control. When this time feedback correction coefficient increases to a predetermined value or more, alcohol content in fuel is decided to be high, and a rich side integral unit amount, in which a lean side integral unit amount is multiplied by the content, is obtained by reading the alcohol content stored in memory corresponding to the feedback correction coefficient.

Filed: 1977-11-22
Abstract: PURPOSE: To detect a steel sheet without any error signal by placing a radiation  thermometer at the outside of a hole made in the lining refractory material of a heating furnace and setting a dome provided with a forced cooler to the inside of the furnace after which each sheet is fed between them.  
     CONSTITUTION: Hole 7 for taking in heat radiation is made in upper lining refractory material 3 of furnace 1, radiation thermometer 8 is placed at the ceiling of hole 7 outside the furnace, and dome 9 as a cold point is set to the inner wall of the furnace on the extension of the axis of thermometer 8. Dome 9 is forced to cool and kept below the surface temp. of material 3. In case a sheet is absent, thermometer 8 measures the surface temp. of dome 9. When sheet 4 is fed, it measures the surface temp. of sheet 4. According to the difference in temp., the sheet is detected. By the detector error signals are eliminated, and hence cleaning and maintenance costs are reduced. The detector is suitable for use in a soaking period, and it has the advantage of measuring the sheet temp. besides detection.

Title: Fire shutter
Inventor: NEMOTO YOSHIYUKI
IPC: E06B9/80
Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To provide a fire shutter capable of performing the safety operation such as stopping when it senses an obstacle during lowering operation and resuming lowering operation immediately when the obstacle is removed. SOLUTION: When a fire signal is received, lowering operation is started at S11, and if an obstacle sensing signal is not received while lowering operation is continued, the operation stops at a lower limit at S15 by looping S11, S12, and S15, thereby completing the flow and closing a shutter completely. When the obstacle sensing signal is received, the operation is shifted from S12 to S13 to stop the lowering operation and advances to S14 to wait until an obstacle is removed. When the obstacle is removed, an obstacle sensing part transmits a flickering signal, and a control part receiving the flickering signal returns to S11 from S14 to resume the lowering operation.
