Title: Combustible gas sensor
Inventor: TAKEUCHI TAKAYUKI
IPC: G01N27/41
Filed: 2001-03-15
Abstract: PROBLEM TO BE SOLVED: To improve measuring accuracies by preventing sensor outputs from being affected by pressures and flow velocities when detecting combustible gases with a negative pressure and a high concentration such as fuel vapors in intake systems. SOLUTION: A combustible gas sensor element 1 having an oxygen ion conductor 11 and a pair of electrodes 12 and 13 is arranged in the intake system as space where gases to be measured exist to obtain an output corresponding to the concentration of oxygen after oxidizing reactions of gasoline vapors as combustible gases. An electronic controller 6 has a correction means for correcting the deviation of the sensor outputs attributed to changes in pressure and flow velocity and, for example, has the relationship of the sensor outputs and pressures in the air atmosphere as a reference gas previously as a map. When the ratio of the reference output and sensor output values is calculated under a measuring pressure, the output ratio is constant regardless of the pressure thereby enabling the calculation of the concentration of the combustible gases from the resulting value.

IPC: H04N5/765
Filed: 2001-04-04
Abstract: PROBLEM TO BE SOLVED: To provide an electronic camera that informs a photographer about possibility of occurrence of a deteriorated image caused attending electronic zoom-up. SOLUTION: In the case of increasing a magnification of electronic zoom-up, a CPU 439 discriminates whether or not the number of pixels read from a CCD 214 after the electronic zoom-up is the number of pixels recorded in a memory card 424 or below. When the CPU 439 makes an affirmative discrimination, the CPU 439 transmits a command to an in-finder display circuit 440 to allow a display element 410 in a finder to make a warning display. The CPU 439 disregards a zoom-up operation signal from a zoom operation button 462 while a timer 445 counts one second in matching with the warning indication. Thus, the CPU 439 stops the electronic zoom-up for one second. The CPU 439 restarts the electronic zoom-up after a lapse of one second.
