In a motor driving control device, a high-frequency alternating voltage or rotation voltage (having a frequency of ωh) is applied to a motor so that magnetic saturation occurs in the motor, thereby extracting, from a γ-axis current, a high-frequency second-harmonic component (a frequency component of 2×ωh) that is obtained by attenuating at least a direct-current component of the γ-axis current. The polarity checker detects the polarity of the magnetic pole of the rotor based on the difference, caused by magnetic saturation, between the positive and negative amplitudes of the high-frequency second-harmonic component.

There is disclosed a method of inspecting the outer wall of a honeycomb structure body which can be performed without relying on human sensory functions and in which a defect detection level and an inspection time per honeycomb structure body are constant, so that stable inspection can be performed. In a method of inspecting the outer wall of a honeycomb structure body 1 made of a ceramic material, while rotating the honeycomb structure body 1, the outer wall of the honeycomb structure body 1 is imaged by a line camera 2, and the thus obtained image is processed to judge whether or not a defect is present in the outer wall of the honeycomb structure body 1.

An oil condition sensor includes rod-shaped electrodes and an opposed cup-shaped electrode. The rod-shaped electrodes are connected to a first power supply through first fixed resistors having a predetermined threshold. The voltage from the first power supply is applied through the respective rod-shaped electrodes to first inputs of respective operational amplifiers. The sensor further includes a second power supply which produces a voltage applied to second inputs of the respective operational amplifiers. Each operational amplifier produces a predetermined voltage if the voltage applied to the first input falls below the voltage applied to the second input. The output of each operational amplifier is connected to the second input through a second fixed resistor. There is a hysteresis relation between the input and output of the amplifiers, so that once an operational amplifier produces voltage, even if voltage from the corresponding conductor falls thereafter, the operational amplifier continuously produces voltage.

In accordance with an increase in speed, a wiring structure has rapidly become more microscopic and thinner and a wiring layer has become extremely thin, and therefore, giving a contact load to a probe for the inspection as has been conventionally done causes damage to a wiring layer and an insulation layer because the probe penetrates not only the oxide film but also the wiring layer or because of a concentration stress from the probe. On the other hand, decreasing the contact load causes unstable continuity between the probe and an electrode pad.It is an object of the present invention to surely and stably inspect an object to be inspected by breaking an oxide film with a low stylus pressure.The present invention is a probe that comes into electrical contact with an object to be inspected when inspecting an electrical characteristic of the object to be inspected, the probe including: a probe main body having a contact portion that comes into contact with the object to be inspected; and a plurality of conductive materials having tip portions projecting from the contact portion of the probe main body.

Provided is a pattern inspection apparatus including: a charge formation means which forms charge on a surface of a substrate (7) by generating an electron beam from a second electron source (20) which is different from an electron source (1) which generates an electron beam before irradiating an electron beam (3), a current measuring means (34) which measures a value of current flowing in the substrate while the charge is formed on the surface of the substrate by the charge formation means; and an adjustment means (37) which adjusts the charge formed by the charge formation means so that the value of the current measured by the current measuring means is a predetermined target value. Provided is also a pattern inspection method which uses the pattern inspection apparatus. Thus, it is possible to easily set an optimal condition of precharge executed before inspection of a pattern formed by a semiconductor apparatus manufacturing process and automatically inspection whether the precharge is good. Then, the inspection result is fed back to the operation afterward. This prevents lowering of the reliability of the inspection result and always enables a stable inspection.
