  • Patent number: 6418354
    Abstract: The width of bands to be laminated on a mill train is adjusted by vertical upsetting rollers, resulting, however, in a narrowing at the band ends due to the asymetric material flow there. In order to solve the problem, the upsetting rollers are so designed as to move at the passage of the band ends in keeping with a curve defined according to specified parameters. The parameters are based on neuro-computer made predictions related to the milling process.

  • Patent number: 6418350
    Abstract: A method for scheduling the allocation of resources in a semiconductor object processing tool. The method comprises identifying a conflict in a resource allocation schedule for the processing of a plurality of semiconductor objects through the tool over time. The schedule utilizes a fundamental period for scheduling the periodic introduction of the objects into the tool for processing. A conflict arising when a transport mechanism adapted to move the objects to and from the resources in the tool is scheduled to execute more than one transport action in a given time interval. The time blocks associated with the conflict are rescheduled from a present time interval to a different time interval such that the rescheduling of the time block does not violate a post-processing residency constraint for a residency time that the object spends in the resource whose time block is rescheduled.

  • Patent number: 6415193
    Abstract: A universal recipe editor is for off-line viewing and editing of semiconductor-manufacturing recipes. The universal recipe editor can read recipes from a wide variety of semiconductor-manufacturing machines from different manufacturers using recipe distributed object model (R-DOM) files. An R-DOM file is generated for each kind of recipe-file format to locate process parameters within proprietary recipe-file formats. The sequence of parameters in the R-DOM file matches the sequence in the recipe data file so that parameters may be mapped from recipe data files for display and editing. ASCII or binary recipe file formats are mapped from the recipe data file using R-DOM objects. Revision and authoring information is kept in a recipe information file for each recipe. Each line of the recipe data file can specify a different process parameter. Security or access rights for each parameter is added for each parameter by including security codes on each line in the R-DOM file.

  • Patent number: 6415205
    Abstract: A multiple sensing technology-based occupancy sensor. Ultrasonic and infrared sensors are used to produce first and second occupancy estimator signals that are combined using a fusion based detection algorithm to produce a combined estimator signal. The combined estimator is then used to switch electrical loads when the combined estimator signal is above a predetermined threshold. The result is an occupancy sensor that has a very high probability of occupancy detection and a low probability of false tripping.

  • Patent number: 6377866
    Abstract: A device operable to apply an identification mark to a semiconductor wafer and inspect the applied mark immediately after its application. Engraving information and wafer thickness data are suppled to an engraving device and the engraving operation applies the mark to the wafer accordingly. A camera then reads the applied mark as read information and a comparator compares the read information to the engraving information and an error is determined in an information processing device. In order to maintain efficient operation of the mark application process, the error determined in the information processing device is then used to control the engraving device as it applies identification marks.

  • Patent number: 6339732
    Abstract: A computerized medication dispensing station that addresses anesthesia medication management and tracking problems is disclosed. Medications, including narcotic and non-narcotic, and supplies for use in anesthesia, are stored in secured, semi-secured, and unsecured containers of a mobile station. A computer housed in the station is used to track the anesthesiology items that have been removed from the station. For each item removed, the time of removal, who removed it, and to whom it was administered is tracked. Items that are not administered to a patient are returned to the pharmacy or wasted (i.e., disposed in accordance with regulations). Each type of event (administration to a patient, return, or waste) is documented so that a health care institution can track usage of items, including narcotic medications, for use in anesthesia.

  • Patent number: 6311094
    Abstract: A production plan is made for a production line for producing finished products from a raw material. Based on the stock number of works in respective process steps at a planning time, the number of works processed at the respective process steps up to the planning time is calculated as the current cumulated processed works of the respective process steps. The target of the stock number of works in the respective process steps at a planned time following a passage of a plan period is calculated based on a target production representing the number of finished products outputted up to the planned time and an average cycle time of production from the raw material to finished products. The target cumulated processed works of the respective process steps at the planned time is calculated based on the target of the stock number of works in the respective process steps.

  • Patent number: 6311100
    Abstract: A technique is provided for utilizing a computer system to generate tool paths for the computed aided machining (CAM) in at least four axis of a selected workpiece or part, particularly a complex part having hidden surfaces. The technique involves storing in the computer system both a surface point representation of a workpiece, which representation contains a unique code for each surface point, and a representation of the tool for which the paths are to be generated. The workpiece surface is viewed from a discrete number of orientations and a map of surface points visible from each of the orientations is generated. The map is then used to obtain selected most promising access directions for access to voxels in the delta volume to be removed or for access to surface points for a finishing operation. Such most promising access directions may for example be obtained by thinning an access cone for the voxel/point.

  • Patent number: 6298276
    Abstract: While reading and analyzing embroidery data for sewing, when an X-direction moving amount and a Y-direction moving amount are at most predetermined small amounts and seam stop data indicating a finish stitch-concentrated portion where embroidery operation is repeated over three stitches for a seam stop, is detected, an X-direction moving amount of a second one of finish stitch data is changed, the X-direction moving amount of a third one of the finish stitch data is changed, and finish stitch concentration of the seam stop is resolved by dispersing finish stitch positions. As a result, not only cutting of thread and swelling of a seam can be prevented but also a thread tightening operation can sufficiently be carried out by reducing moving distance of embroidery thread during thread tightening.

  • Patent number: 6289256
    Abstract: A control device controls to move a chucking mechanism part to a first stop height 451 at a first speed, then at a second speed lower than the first speed before the chucking mechanism part comes in touch with a part from the first stop height, and stop when the chucking mechanism part touches the part, thereby to hold the part. So, a shock to the part when the part is held is reduced in the constitution, and the apparatus becomes light-weight because of the elimination of a shock-absorbing mechanism, hence realizing high-speed mounting.

  • Patent number: 6285913
    Abstract: A method for compensating for static friction in an actuating device includes the steps of generating an actual signal y2(t) corresponding to a quantity which is controllable by the actuating device, generating a set value signal y1(t) generating a control signal s1(t) based on the set value signal y1(t) and the actual value signal y2(t), and supplying the control signal to the actuating device for controlling the same. The method also includes the steps of generating an intermittent signal s2(t) compensating for friction, sensing the sign of the derivative with respect to time of the control signal s1(t), giving the signal s2(t) compensating for friction the same sign as the derivative, and adding the signal s2(t) compensating for friction to the control signal s1(t) before supplying the same to the actuating device.
