摘要： According to this dynamic pressure groove processing method, dynamic pressure grooves are formed in specified regions by electrochemical machining with the electrode of an electrode tool put close to a workpiece in the initial stage. Through this electrochemical machining, corners of land portions adjacent to the dynamic pressure grooves can be curved and smoothed. Next, by subjecting the workpiece to electrochemical machining with the electrode of the electrode tool put away from the workpiece, the land portions are to undergo weak electrochemical machining. Surface roughness of surfaces of the land portions can be reduced, and the curved corners of the land portions can be made smoother at the same time. Therefore, the abrasion resistance characteristic of the dynamic pressure grooves can be improved further than that achieved by the conventional electrochemical machining, allowing the abrasion resistance characteristic and reliability to be sufficiently improved.

摘要： It is an object of the invention to provide a thrust dynamic pressure bearing in which an unsymmetrical contact during rotation is prevented from occurring, and a dynamic pressure space is prevented from being clogged with abrasion powder generated by a contact at starting and stopping. In the thrust dynamic pressure bearing of the invention, a flange disposed on a shaft is tapered as moving form toward the outer circumference thereof, so that a dynamic pressure space between a thrust bearing face of a housing and a thrust receiving face of the shaft during rotation becomes wider toward the outer circumference thereof. Even if the shaft is tilted with respect the housing during rotation, therefore, it is possible to prevent an unsymmetrical contact of the thrust receiving face of the shaft in the vicinity of the circumference against the thrust bearing face of the housing, from occurring. In addition, the dynamic pressure space becomes wider as moving toward the outer circumference, so that the abrasion powder generated by the contact at starting and stopping can be easily discharged from a radially inward portion toward a radially outward portion of the dynamic pressure space.

摘要： A substrate inspection system is formed with an inspection device associated with a reflow process at the end of a series of production processes for substrates, image collectors each associated with a different one of the production processes upstream to the reflow process and an image display device for receiving images from the inspection device and the image collector and displaying the received images. The inspection device inspects a specified number of substrates to obtain measured values and calculates a margin for each component with respect to a specified reference value and transmits to the image collectors and the image display device the component code of the component with a small margin value. The image collectors save the image corresponding to the component code from the inspection device. The image display device receives images of the component corresponding to the component code from the inspection device and the image collectors and display images of the same component and the same substrate at each process.

摘要： After a CAD data and a parts library are combined to produce an inspection data, the set data for the inspection window is automatically corrected using the image of a bare board for a board to be inspected. In this correcting process, an inspection window based on the aforementioned inspection data is set on a bare board image, and then an image in the inspection window W4 making up a reference for setting other windows is binarized, and lands 35 on this binary image are detected. Further, on the basis of the detection result, the set position and size of land windows W1 for solder inspection are corrected, after which the set positions of other inspection windows W2 to W4 are corrected.

摘要： When a component is replaced or replenished in a predetermined feeder, mounters 3A and 3B refer to mount data in accordance with the feeder number for the feeder and read out the mounting position of the replaced or replenished component. The mounting position data is transmitted to a substrate inspecting apparatus 5 together with the substrate identification code of a substrate first processed after reel replacement. When the substrate corresponding to the substrate identification code is supplied, the substrate inspecting apparatus 5 refers to substrate inspection data in accordance with the mounting position data, specifies a component to be inspected, and executes the mounting error inspection according to character-string recognition for the specified component. When a mounting error is detected in this inspection, the substrate inspecting apparatus 5 transmits no-good determination to the mounters 3A and 3B receiving information.
