An ion generation device includes an ion generator that generates ions, an ion detector that detects generated ions, a blower that blows the generated ions to outside through a draft air duct, and a control unit that performs drive control of the ion generator and the blower. When the control unit detects absence of generation of ions at a time of starting operation or the like, the control unit stops driving of the ion generator for a short time while keeping the blower driving, and purges staying ions, after which, the control unit carries out ion detection by the ion detector, and determines presence or absence of ion generation. When the control unit determines that ion generation is absent, the control unit continuously performs determination of ion generation a plurality of times, and if ion generation is absent in all the determinations, finally determines generation of ions as absent.

A transfer point of a transfer arm is detected accurately and stably by using a position detecting wafer having an electrostatic capacitance sensor. A position detecting wafer S is formed in a wafer shape transferable by a transfer arm 20 and includes an electrostatic capacitance sensor 50 for detecting a relative position with respect to a reference object by detecting an electrostatic capacitance in relation with the reference object for a position detection. The electrostatic capacitance sensor 50 includes a detection electrode 52 for forming the electrostatic capacitance in relation with the reference object, and the detection electrode 52 is installed on a rear surface of a main body of the wafer shape. Installed on the main body is a guard electrode 100 covering the detecting electrode 52 when viewed from a front surface thereof, for blocking an electric field oriented toward the detection electrode 52 from the front surface.

摘要:
Test sound wave is outputted from a speaker. A movable part of a three-axis acceleration sensor, which is a micro structure of a chip to be tested TP, moves due to the arrival of the test sound wave which is compression wave outputted from the speaker, that is, due to air vibrations. A change in the resistance value that changes in accordance with this movement is measured on the basis of an output voltage that is provided via a probe needles. A control part determines the property of the three-axis acceleration sensor on the basis of the measured property values, that is, measured data.
