Title: Air/fuel ratio control system
Inventor: HOKADO MORIHARU
IPC: F23N1/02
Filed: 1987-04-30
Abstract: PURPOSE:To achieve air/fuel ratio control with which the increase of CO concentration can be controlled and the control becomes not susceptible to external disturbances by shifting from the O2 concentration control to the CO concentration control when the real CO concentration is determined to be on the rise on a long term basis when using fuel whose burning characteristics are unknown. CONSTITUTION:The controller periodically executes the program with data inputs of excess air ratio theta 29 of CO concentration 35, CO concentration deviation 34 and O2 control mode 26, and determines the CO concentration changing rate CO/theta relative to the excess air ratio for every specified cycle TO based on previous values thetai-1, COi-1 and current values thetai COi of the excess air ratio and CO concentration. If the absolute value of CO/theta is more than the specified value Xppm, the CO concentration deviation is evaluated to determine whether it is more than 0ppm. If it is more than 0ppm, a determination is made as to whether the O2 control automatic mode is being assumed, and, if so, a command is given to start the CO concentration control automatic mode. If not, the sampling is made as to the CO concentration only for (m) times, and the average of the CO concentration is determined. Every time the average is computed as the latest data for a CO concentration setting unit 15, the setting data are revised to correct the setting of the CO concentration setting unit 15.

Title: Bar code reader
Inventor: YAGI TOSHIYUKI
IPC: G06K7/00
Filed: 1979-08-15
Abstract: PURPOSE: To increase the reading efficiency by analyzing the module number of the bar based on the width of the bar scanned just before the relevant bar when the scanning is carried out by applying the hand scanner to the bar code symbol.  
     CONSTITUTION: The hand scanner 2 is operated manually on the bar code symbol 1 which is coded in combination of the bars having the different colors. Thus the optical signal changing in the lapse of time is received 4 and then converted into the electric signal. And this electric signal is analyzed by the analyzer 5. In this case, the module number of the bar when the scanning is carried out by applying the scanner 2 to the symbol 1 is analyzed based on the width of the bar scanned just before the relevant bar. As a result, a compact and lightweight structure is realized for the analyzer, at the same time reducing the effect of the fluctuation of the scanning velocity and thus increasing the reading efficiency.
