When the electrode potential of a charge control electrode above a wafer is reduced, image brightness is reduced. A point of change in the image brightness is a switching point between a positively charged state of the image and a negatively charged state of the image, showing the weakly charged state of the image. By setting this point of change as an inspecting condition, the amount of electric charges on the surface of the wafer can be reduced, and stable wafer inspection can be performed. It is estimated that an applied voltage V1 in FIG. 14 corresponds to the point of the change and is roughly included in the voltage range of a region enclosed by a broken line in the vicinity of the applied voltage V1. Within this voltage range, the influence of charge on an inspection under the inspecting condition can be reduced.

The present invention is a method for inspecting a surface of an article through an image thereof by photographing a surface to be inspected of the article with a CCD camera, in which the surface of the article is inspected by selecting two arbitrary pixels from among pixels showing the surface to be inspected in the image and comparing the two pixels. When the two pixels are selected, for example, pixels in point-symmetry or line symmetry can be selected. Further, the two selected pixels are compared, for example, in brightness.

To hold an engine cover in a door opening state by operation of only one hand, and to ensure a large opening angle in the door opening state.A guide hole 28 made from a long linear guide portion 28A and a V-shaped guide 28B is provided on a stay guide 27 of a door opening holding mechanism 21. A first bending portion 28B1 of the V-shaped guide portion 28B is formed so as to curve along a moving track 25 when a tip end side of a stay 22 rises and falls at a position on an opposite side to the linear guide portion 28A. A second bending portion 28B2 is formed from an end portion of the first bending portion 28B1 to have a shape which is generally bent in a V-shape, and extends outward in a diameter direction of the moving track 25 in regard to the first bending portion 28B1. When the engine cover 14 is held in the door opening state, the tip end side of the stay 22 is hooked to the second bending portion 28B2 to be locked.

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.

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.

A conveying apparatus is provided with a rotary disc portion with a suction means which forms a slit on an outer peripheral surface and sucks through the slit so as to convey a conveyed article in a state of holding the conveyed article by suction to both sides of the slit, and a linear conveying portion with a suction means which sucks the conveyed article riding over a pair of parallel conveying belts through a gap between the conveying belts so as to convey the conveyed article in a state of holding the conveyed article by suction to the conveying belt, and has one end opposing to the outer peripheral surface of the rotary disc portion so as to be capable of transfer the conveyed article. The conveying apparatus of the invention, the inspecting apparatus and an aligning and supplying apparatus allow for execution of a side surface inspection of a small article stably without requiring a lot of space.

A robot includes, a holding unit configured to hold an object, an image pickup unit, and a predetermined first portion of the robot. The image pickup unit picks up images of the holding unit and the object using the first portion as a background.

The invention discloses a robot for high-voltage cable maintenance. The robot comprises a robot driving device, a top of the robot driving device is fixedly connected with a rope meshing device through clamping devices arranged on a left side and a right side, a cable limiting groove is formed in the side, opposite to the robot driving device, of the rope meshing device, and a detection device isarranged in the middle of the cable limiting groove. In the invention, the robot driving device is improved; a reverse motor can make a driving wheel rotate in a forward direction and a reverse direction so that the whole device can be controlled to move back and forth on a cable; the driving wheel is lapped on the bottom surface of the cable when the equipment is mounted on the cable; when the driving wheel rolls, the whole device can be driven to walk on the cable, and an electric push rod is arranged; and the electric push rod can move upwards when the cable goes up a slope or goes down a slope quickly so that the driving wheel can be attached to the cable more tightly, stability of an inspection process can be guaranteed, and detection precision is improved.

In a defect inspection system using a plurality of detectors such as an upright detector and an oblique detector, if illumination light and wafer height are adjusted to the detection field of view of one detector, a defocused image is detected by other remaining detectors, resulting in degradation of the detection sensitivity. The present invention solves this problem.

When a plurality of detectors such as an upright detector and an oblique detector are used in the defect inspection system, the reduction of the inspection sensitivity can be prevented by correcting the field positions of the other remaining detectors with respect to the field of view of the one detector. Further, the variation in optical axis for each inspection system due to the variation in parts and assembly errors can be reduced.
