摘要： A flow path from outer gas introduction apertures 144a to inner gas introduction apertures 134a has a narrower-width flow passage formed by an inner wall member 150. This structure effectively lowers the probability that a liquid, such as water, entering from the outer gas introduction apertures 144a passes through a gas inflow chamber 122 and reaches a sensor element 110, compared with a structure without the inner wall member 150. The inner wall member 150 is formed as a solid member that is capable of storing the surrounding heat. Even if there is a certain event that has the potential of causing a temperature decrease of the sensor element 110, for example, an abrupt change in flow rate of an object gas, the heat stored in the inner wall member 150 effectively prevents a temperature decrease of the sensor element 110. This structure prevents the occurrence of cracking in the sensor element 110, compared with a conventional sensor structure having a double-layered protective cover.

摘要： First outer gas apertures 144a are arranged in a first corner 144b such that the outer opening plane of each first outer gas aperture 144a forms an angle of 45 degrees with a bottom face of a step element 145 and the outer opening plane forms an angle of 90 degrees with an inner circumferential face of the first outer gas aperture 144a. Second outer gas apertures are arranged in a second corner 146b such that the outer opening plane of each second outer gas aperture 146a forms an angle of 45 degrees with a bottom face of an edge section 146 and the outer opening plane forms an angle of 90 degrees with an inner circumferential face of the second outer gas aperture 146a.

摘要： There is provided an inkjet printing apparatus which can output a stable image without density unevenness by performing appropriate drive control to print elements based upon an appropriate representative temperature of a chip whatever image data is printed on a print medium. For this purpose, detection temperatures of a plurality of temperature sensors are lined up in high temperature order, and coefficients by which the respective detection temperatures are multiplied, are determined to be associated with that order at the lining-up, determining a representative temperature by the weighted average method. The common drive pulse associated with to the individual chip based upon the representative temperature thus obtained, to be applied thereto. Thereby even if temperature variations of print elements on the chip exist, it is possible to appropriately control the entire chip in temperature.
