The invention provides a polishing pad conditioner that enables stabilization of brazing metal melting point, minimization of abrasive grain detachment by uniformizing and stabilizing abrasive grain brazing condition, and enhancement of flatness by minimizing thermal deformation of the metal support. The polishing pad conditioner is fabricated by brazing multiple abrasive grains to the surface of a metal support with brazing metal, wherein the composition of the brazing metal expressed in mass % is such that 70%≦Ni+Fe≦90% (provided that 0≦Fe/(Ni+Fe)≦0.4), 1%≦Cr≦25%, 2%≦Si+B≦15% (provided that 0≦B/(Si+B)≦0.8), and 0.1%≦P≦8%.

摘要:
An automobile air conditioning device includes a ventilation system with a ventilation fan for discharging air contained in a passenger chamber from the vehicle. A dew condensation detector is adapted to detect a predetermined relative humidity for a dew point at which dew condensation on a rear window glass of the vehicle is presumed to occur. A controller actuates the ventilation system when the dew condensation detector detects the dew point while the vehicle is running.
