    摘要: In the thermal process air flow meter according to the invention first, second and third electrode terminals are arranged on the same surface at one end of a substrate. A first exothermic resistor is connected between the first and second terminals, and a second exothermic resistor is connected between the second and third terminals, with the first exothermic resistor on a front surface of a substrate and the second exothermic resistor on the opposite (back) surface. The substrate may also carry the semiconductor elements of an electronic circuit used to analyze electric signals from the terminals. In a preferred embodiment of the invention, the substrate is mounted at an incline relative to the direction of unobstructed air flow in the air passage.

    摘要: Corrosion resistant material is used for lead wires of the thermistor, and an exposed portion of electrodes of the thermistor and a portion surrounding a weld portion of the lead wires are coated with corrosion resistant material. Since the lead wires themselves are made of corrosion resistant material, no corrosion occurs in the welding portion and a cut working portion. Further, the lead wires and the exposed portion of the electrodes are coated with corrosion resistant material. Thereby an electronic device having extremely high corrosion resistivity and hence high durability and reliability is produced, with the result that the electronic device can be used for a long period without corrosion under the heavily corrosive environment, such as sulfur dioxide gas atmosphere.

    摘要: A method and apparatus for producing index prints makes the trend of compensation for main prints coincide with the trend of compensation for the index prints. When a scanner determines an exposure compensation amount for each frame based on image data of each frame of a negative film, the information representing the exposure compensation amount for each frame is transmitted to the drive controllers via a controller. In a main print section, an exposure process is performed by the drive controller based on the information regrading the exposure compensation amount for each frame, thereby obtaining a main print. In an index print section, an exposure process is performed by the drive controller based on the same information regrading the exposure compensation amount for each frame, thereby obtaining an index print. Also, a density adjusting method easily and automatically adjust unevenness in density produced in an image printing stage. In a test mode, an image (gray image) with a uniform intermediate gradation is printed on a printing paper. A pixel having the maximum density is selected. Differences in density between the pixel having the maximum density and other pixels are calculated, and the gradations of the respective pixels are shifted based on the differences. Thus shifted gradations are registered as standards for the respective pixels.

    摘要: An air flow rate meter for detecting an air flow rate in a wide operating temperature range. A heating temperature of a heat generating resistor for detecting an intake air flow rate is set on the basis of an intake air temperature or a current flowing through the heat generating resistor. The heating temperature of the heat generating resistor is kept at an optimum value determined from a look up table stored in a read only memory.
