In a disk drive device having a double cover structure with low-density gas enclosed therein, embodiments of the present invention allow a more reliable leak inspection to be performed on the second cover and to prevent defects caused by joining the secondary cover. An HDD according to an embodiment of the present invention comprises a ventilation path from a ventilation hole on an inner cover to a space between the inner cover and an outer cover.

The invention discloses a rigid body mode testing method for a powertrain mounting system under the loading condition. In the method, a heavy object is hung on a powertrain mounting device under the loading condition; and a rope for hanging the heavy object is cut to suddenly release the force acted on the powertrain mounting device so as to excite the free vibration of the powertrain mounting device and immediately trigger a data acquisition unit to record and store the data on a vibration transducer at the moment. A rigid body mode of the mounting system is tested by the method and the obtained each-order natural frequency and decoupling rate are the actual and real natural frequency and decoupling rate of a tested vehicle, so that the method tests the performance of the vehicle most directly, really and reliably. The testing method can be performed on any entire vehicle, only a proper number of heavy objects is needed, and the design and processing of a test bench are avoided, so that the testing cost is basically avoided. Obviously, the testing time and the testing cost are greatly saved.

A pattern defect inspection apparatus is capable of detecting defects, without being affected by non-uniform thickness of a thin film formed on a sample, even when using monochromatic light, such as a laser. The apparatus comprises a laser to illuminate a sample, coherence suppression optics to reduce laser beam coherence, a condenser to condense the laser beam onto a pupil plane of an objective lens, and a detector to detect the light reflected from a circuit pattern formed on a sample. The condenser is designed so that the intensity of light illuminating the sample under test can be partially adjusted according to the type of laser beam illumination condensed on the pupil of the objective lens. Variations in reflected light intensity caused by non-uniform film thickness on the surface of the sample are therefore reduced, and shading is minimized in the detected image to allow detecting of fine defects.

A tire shape inspection method executes the following steps: first, as a teaching operation step, boundary lines of the bulge and dent marks are detected in a sample source image of a sample tire, a mask image is generated which denotes the boundary lines, regions are removed from the sample source image which correspond to the boundary lines which are denoted in the mask image, and a height offset image is generated which represents the heights of the remaining regions with one or more offset values. Next, as an inspection operation step, the height offset image is subtracted from an inspection image of the inspection tire, the boundary regions which the mask image represents are removed, and, on the basis of the obtained bulge/dent removal image, shape defects of the sidewall surfaces of the inspection tire are inspected.
