摘要:
A data display apparatus and method for displaying the result of a data mining process as multi-dimensional data. In one embodiment, the multi-dimensional data is displayed on a parallel coordinate axis. An engine unit executes the data mining process on displayed multi-dimensional data according to an instruction from a visual data mining tool and transfers the result to the visual data mining tool. The user interface unit of the visual data mining tool generates an axis corresponding to the result of the data mining process, adds the axis to the parallel coordinate axis and displays the result of the data mining process on the added axis.
摘要:
When multi-dimensional data for specifying search conditions is input, a plurality of combinations of the search conditions are automatically generated from the multi-dimensional data. Then, a plurality of search results for the plurality of combinations are obtained, and output as multi-dimensional data.

An information processing apparatus searches for documents with access rights created for them. A file information obtaining section obtains predetermined information from a file. A right information obtaining section obtains right information indicating a user who can access a file. An index storing section stores an index in which information obtained by the file information obtaining section is associated with right information obtained by the right information obtaining section. A keyword inputting section accepts keyword input for searching for a file. A user specifying section specifies a user who inputted a keyword. A search query generating section generates a search query from a keyword input from the keyword inputting section and information indicating a user specified by the user specifying section. A searching section searches the index storing section for an index corresponding to a search query generated by the search query generating section.
摘要:
A piston driving device for dispensing a predetermined small amount of paste-like material from a nozzle in response to an electrical signal without any time-delay is enabled by the slow rotation of a ball-screw shaft, the rotation being reduced by a differential gear system. A female ball-nut fitted onto the ball-screw shaft causes a piston plunger to advance at very low speed such that dispensing of the predetermined volume of paste-like fluid is possible. Vertical motion of a nozzle is compensated by vertical motion of a piston driving device such that the relative position of a piston against a nozzle is unchanged.

A component mounting machine for mounting electronic components onto a plurality of circuit boards in high speed with a simple structure is disclosed. The electronic component mounting machine includes a board conveyer section which has first and second positioning areas, where the first positioning area is movable in the Y direction, and a plurality of transport units, each unit having a plurality of component pick-up units and being movable independently in the X direction on a same X-guide.

A device for supporting magnetic heads for double sided magnetic discs includes two pivot points for both the upper and lower magnetic head support plates in a manner that the connecting line of both upper pivot points and the connecting line of both lower pivot points are crossing. The degreee of contact between the magnetic heads and a magnetic disc is improved since both support plates are incorporated with each other to absorb the opposite side's deflection.

A shock absorbing apparatus for loading a magnetic disc onto a disc drive comprises disc positioning pins equipped with shock absorbing devices which effectively load the magnetic disc smoothly, without shocks. The pins hold a collar in place using a coil spring and a ball placed in a hole drilled into the side of the pin. The collar is thus allowed to move up and down freely, its motion controlled by a sliding disc holder. The collar thus absorbs shocks to the magnetic disc normally encountered when loading such discs on a conventional disc drive.

An electronic parts mounting device of the type including a head movable along the upper surface of a substrate and in the directions of X- and Y-axes for, arranging electronic parts at predetermined locations on the substrate. The device comprises a frame, a spindle mounted on the frame rotatably and movably in the vertical directions with the upper end being connected to the vacuum source and the lower end having a nozzle for absorbing the electronic parts, a rotatable device rotatable relative to the frame and connected to the spindle displaceably in the axial directions and not rotatably relative thereto. A locator supporting device for supporting at least one pair of locators with the lower ends of which opposing the tip end of the nozzle and for clamping and retaining the electronic parts absorbed on the nozzle, and the locators supported rotatably around the horizontal axis and connected to the spindle so as to displace in the axial direction and non-rotatably, and connected to the rotatable device, and a locator rotating device for rotating the locators to close the locators when the locators and the nozzle are at the same level.
摘要:
A magnetic disk positioning device for loading a magnetic disk onto a disk drive comprises a driving pin projecting from a turntable. The driving pin, which is positioned within a triangular hole defined within the disk drive turntable, is capable of moving in both the radial and circumferential directions. Upon loading, the driving pin initially slips into a rectangular shaped hole provided in the disk hub. As the disk rotates further, the driving pin is clamped by a slanting side of the triangular hole and two sides of the rectangular hole. By securing the position of the driving pin, the invention enables a magnetic disk to be accurately and consistently positioned at the desired point within the disk drive and so allows more precise recording and replaying.

A magnetic disk positioning device for loading a magnetic disk onto a disk drive comprises a driving pin projecting from a turntable. The driving pin, which is positioned within a triangular hole defined within the disk drive turntable, is capable of moving in both the radial and circumferential directions. Upon loading, the driving pin initially slips into a rectangularly shaped hole provided in the disk hub. As the disk rotates further, the driving pin is clamped by a slanting side of the triangular hole and two sides of the rectangular hole. By securing the position of the driving pin, the invention enables a magnetic disk to be accurately and consistently positioned at the desired point within the disk drive and so allows more precise recording and replaying.
