Abstract: Equipment extracts components of spatial frequency that need to be evaluated in manufacturing a device or in analyzing a material or process out of edge roughness on fine line patterns and displays them as indexes. The equipment acquires data of edge roughness over a sufficiently long area, integrates a components corresponding to a spatial frequency region being set on a power spectrum by the operator, and displays them on a length measuring SEM. Alternatively, the equipment divides the edge roughness data of the sufficiently long area, computes long-period roughness and short-period roughness that correspond to an arbitrary inspection area by performing statistical processing and fitting based on theoretical calculation, and displays them on the length measuring SEM.

Abstract: A vehicle wheel comprises a rim (172) and a disk section (171) separate from the rim. Since the disk section is separate from the rim, the freedom of designing the disk section is improved. The rim comprises an outer rim (178) and an inner rim (181) separate from the outer rim. The outer and inner rims are attached to the outer periphery of the disk section at the same place by welding.

Abstract: The present invention may include a pattern inspection method of extracting a pattern edge shape from an image obtained by a scanning microscope and inspecting the pattern. A control section and a computer of the scanning microscope process the intensity distribution of reflected electrons or secondary electrons, find the distribution of gate lengths in a single gate from data about edge positions, estimate the transistor performance by assuming a finally fabricated transistor to be a parallel connection of a plurality of transistors having various gate lengths, and determine the pattern quality and grade based on an estimated result. In this manner, it is possible to highly, accurately and quickly estimate an effect of edge roughness on the device performance and highly accurately and efficiently inspect patterns in accordance with device specifications.

Abstract: Achieving efficient analysis of search results, which is required for the examination of search queries, by listing up both title information of a retrieved document group and the whole information. By arranging search results display area and topic word display area adjacently on a retrieval assisting interface, the title information and topic information can be browsed by users; by arranging search results analysis means such as mark title button for emphasizing documents containing designated topic words, along with mark topic word button for emphasizing topic words contained in a designated document, users can analyze search results readily from various standpoints.

Abstract: A document retrieval assistance method has a user interface with an interactive guidance function. In response to a search query, search results including a title list of retrieved documents is displayed alongside a separate display of topic words extracted from the retrieved documents which reflect the search results. In particular, a topic-word graph is displayed alongside a list of titles of the retrieved documents and the interface enables browsing of the documents using the topic words. Further, the interface permits emphasized display of the list of titles of the documents through direct selection of the titles displayed in the list or through selection of the topic words. Further, an associative search can be executed using a selected document to refine the original search results and develop updated displays of the search results and topic words contained in the documents.

Abstract: A large-diameter part, the diameter of which is larger than the diameter in the center, is provided at the edges of a rim via parts having a difference in a level. Curled parts are provided on both edges of the rim by curling the large-diameter part. Each end face of the curled parts is touched to the parts having a difference in a level. The rigidity of the side of the edge of the rim can be enhanced by providing the parts having a difference in a level to the rim. As a result, the rigidity of the whole wheel can be enhanced and in addition, as a disc and the rim are not required to be thickened, the weight of the wheel can be prevented from being increased.

Abstract: The present invention provides a circuit pattern edge inspection method of finding out a failure in a fabricating process and image distortion in an observing apparatus by analyzing, by a non-destructive inspection, the shape of an edge of a line of a fine pattern in which characteristics of the material, process, and an exposure optical system in a semiconductor fabricating process appear, and performing analysis quantitatively. The method includes a step of detecting a set of edge points indicative of positions of edges of the pattern in a two-dimensional plane by a threshold method; a step of obtaining an approximation line for the set of edge points detected; and a step of obtaining an edge roughness shape and a characteristic by calculating the difference between the set of the edge points and the approximation line. A plurality of values are used as thresholds used for the threshold method.

Abstract: In a four wheel drive type buggy, an output shaft of an engine is connected to a front wheel propeller shaft and a bevel gear of a front wheel differential gear via a connecting pipe. The front wheel propeller shaft is provided with a large diameter section around an outer periphery surface thereof near and behind a rear end opening of the connecting pipe. A dust cover covers the outer periphery between the large diameter section and the rear end opening and a band fastens both ends of the cover. The large diameter section has approximately the same diameter as the outer diameter of a spline section formed at the tip of the front wheel propeller shaft. When connecting the front wheel propeller shaft to the connecting pipe, the spline section is insertable into the free opening of the dust cover, with the dust cover previously covering the outer periphery surface of the rear end opening.

Abstract: A card-type electronic device including at least a circuit board, wherein the circuit board includes a part mounting portion partially surrounded by a cutout portion and mechanically and electrically connected to other portion of the circuit board via a flexible supporting portion. The flexible supporting portion is bent so that a height position of the part mounting portion is different from a height position of a remaining portion of the circuit board.

Abstract: In an I/O card that can be inserted into a slot of an electronic device and supplied with electricity therefrom, a first connector can engage a connector provided in the slot of the electronic device. A second connector can engage an external connector of an interconnection cable used to connect the I/O card to an external device. A circuit notifies the electronic device that the I/O card has been loaded to the slot thereof when the external connector is connected to the second connector of the I/o card inserted into the slot. The I/O card receives a supply of electricity from the electronic device, the supply being started after the electronic device is notified by the circuit.
