摘要： A reflecting member made from a tube-shaped member has an inner peripheral surface that structures a reflecting surface on an axis of the tube-shaped member. A slope, relative to the axis, of a tangent line of the inner peripheral surface in a cross-sectional plane containing the axis changes monotonically along the axis. In relation to a target facing a smaller opening of the tube-shaped member, at a specific distance therefrom, and having a flat region perpendicular to the axis and axially symmetrical relative to the axis, of an electromagnetic radiation incident along the axis from a larger opening of the tube-shaped member, that radiation reflected at a specific location on the larger opening side is incident on one end side of the flat region, and that radiation reflected at a specific location on the smaller opening side is incident on the other end side of the flat region.

摘要： To provide a pressure sensor housing that is less likely to cause temperature distribution inside a pressure sensor when the pressure sensor is disposed inside a heater block, a pressure sensor housing includes a hollow cylindrical member extending along a predetermined axis core. A pressure sensor element that detects the pressure of a fluid is accommodated inside the cylindrical member. The entire circumference of a side surface thereof is surrounded by an air layer in the first posture in which an axis core of a space is aligned with the predetermined axis core with the hollow member disposed in the space. The side surface is in contact with a wall surface defining the space at a plurality of points at the same time in a second posture, which is at least one of postures in which the predetermined axis core is eccentric with the axis core of the space.

摘要： A current discharge probability of a flame sensor is calculated based on the number of drive pulses applied to the flame sensor and the number of discharges determined to have occurred in the flame sensor after receiving the drive pulses. Degradation indices (degradation progress and remaining lifetime) indicating the current degradation state of the flame sensor are calculated based on the calculated current discharge probability of the flame sensor.
