摘要： A detection signal corresponding to a change of the status of an object to be observed can be easily transmitted to a desired location without any complicate installation and adjustment for use. An AE sensor (21) is disposed at an appropriate position on the perimeter of a rotation chuck (4) to which a workpiece (5) is attached. A signal transmitting part (101) is disposed in the hollow part of the rotation chuck (4). A signal receiving part (102) is disposed at an appropriate position on a base part (3) having the rotation chuck (4). The signal transmitting part (101) causes the AE sensor (21) to transmit, by wireless, a detection signal, which is received by the signal receiving part (102), then demodulated, and then subjected to a signal processing and the like.

摘要： A vitrified grinding wheel having a porosity (desirably 30 to 70 vol.%), a concentration ratio of abrasive grain (desirably 50 to 160), and an abrasive grain size (desirably 10 to 90 mum) based on pre-set grinding efficiency and grinding accuracy, desirably, a grinding accuracy of 0.1 to 1.6 Rz (mum) and a grinding efficiency of 0.1 to 2.0 mm /(mm.sec), and a method of manufacturing the vitrified grinding wheel.
