    • PROBLEM TO BE SOLVED: To obtain an inductively coupled plasma (ICP) alignment apparatus that dispenses with the movement of a bulky and heavy RF electronic circuit, can suppress RF radiation, and has small adjustment width for impedance matching. SOLUTION: The ICP alignment apparatus comprises: a coil 10 for generating an ICP in a gas; a torch 20 passing at least partially through the coil 10; and an adjustment mechanism 80 for adjusting the position of the torch 20 to the coil 10 so that the arrangement of a torch axis 200 to a coil axis 100 changes. The adjustment mechanism 80 may adjust an angle and/or a distance between the axis of the coil 10 and the torch axis 200. The torch axis 200 may be held substantially parallel to the coil axis 100, while the adjustment mechanism adjusts a distance between the torch axis 200 and the coil axis 100. The coil 10 is preferably maintained substantially fixed in position with respect to a sampling aperture for sampling photons or ions originating from the inductively coupled plasma.

    • PROBLEM TO BE SOLVED: To provide charged particle spectroscopy system which can provide high-sensitive spectral observation of secondary charged particles to generate high-quality sample optical images.
      SOLUTION: The primary particle-based spectroscopy system (10) achieves sample observation approximately perpendicular to the sample surface and collection of secondary charged particle. In this system, a collection chamber (22) provided with through hole (52) converges discharged particle in downstream direction along the 1st vertical axis (24). By this process, both the secondary charged particle lens system (20) for demarcating optical crossover point (25) of the charged particle and the light reflex optical device (50) located downstream of the lens system, which is designed to receive imaging light (41) and reflect it so as to be kept away from the 2nd vertical axis (42) for providing surface-observable images, are arranged on the crossover point (25) or near. Thus the converged particle may pass through the aperture in order to take spectroscopic analysis in downstream without almost being interrupted by optical device.

    • PROBLEM TO BE SOLVED: To provide a method for overspeed prevention comprising monitoring whether or not the actual operation parameter of a rotor falls within the specified range of an expected parameter value and limiting the rotor speed according to the actual parameter. SOLUTION: This method comprises the step of determining whether or not the actual parameter of a rotor falls within the specified range of an expected parameter value and the step of limiting the operation speed when the actual parameter value does not fall within the specified range of the expected parameter value. Evaluation is made of at least one of the parameters: (i) the energy necessary to accelerate the rotor from a zero speed to a specified speed, (ii) a change in the energy necessary to accelerate the rotor from a first speed to a second speed, (iii) the energy loss pertaining to the windage of the rotor, (iv) the time necessary to accelerate the rotor from the first speed to the second speed, (v) the speed of the rotor at a specified time, and (vi) the ratio of the drag coefficient to the inertia.
