A position detecting device is provided, which is configured to minimize leakage of magnetic flux in an electromagnetic induction system. Furthermore, the use of the two-component mortar composition for chemically fastening anchoring means in boreholes of different mineral substrates is also described. The elevator car may be at least partially supported by the hoisting ropes to move the elevator car. That selective doping provides an edge zone that does not convert to hemispherical grain silicon during manufacturing. in a diode or a transistor, for increasing radiation resistance. An abrasive component of the friction material includes non-fibrous particulate matters having the same material as fibrous matters of rock wool, slag wool, and ceramics including Al2O3SiO2 as a main component, but the fibrous matters are not contained.
