Patent number: 6311094Abstract: 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.Type: GrantFiled: August 25, 1998Date of Patent: October 30, 2001Assignee: Kabushiki Kaisha ToshibaInventors: Ken Iriuchijima, Hideo Sakamoto, Mutsumi Fujihara

Patent number: 6311100Abstract: 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.Type: GrantFiled: September 14, 1998Date of Patent: October 30, 2001Assignee: Mass. Institute of TechnologyInventors: Sanjay E. Sarma, Putta Laxmiprasad, Mahadevan Balasubramaniam

Patent number: 6298276Abstract: 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.Type: GrantFiled: November 16, 1998Date of Patent: October 2, 2001Assignee: Brother Kogyo Kabushiki KaishaInventor: Yuji Iida

Patent number: 6289256Abstract: 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.Type: GrantFiled: January 15, 1998Date of Patent: September 11, 2001Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takeshi Takeda, Yoshihiro Mimura, Noriaki Yoshida, Akira Kabeshita

Patent number: 6259956Abstract: A method and apparatus for monitoring and maintenance of unattended robot liquid storage and dispensing sites, including a site controller and site monitor. The site monitor continuously appends text strings received from the site controller to HTML text log files and HTLM text report files and simultaneously compares the stored text strings representing site events to be monitored with evaluation messages. Each evaluation message is linked to an alert code, which in response to an evaluation message text string match initiates a particular set of responses, including sending notice of site failures and other remote site information to a home office via fax, pager and/or email. The site monitor also collects the information gathered from the site controller, the tank monitor, alarm system and any other site devices and stores the information in a one or more HTML text files, which information then takes the form of a web page with hypertext links to images related to the stored information.Type: GrantFiled: January 14, 1999Date of Patent: July 10, 2001Assignee: Rawl & Winstead, Inc.Inventors: Robert J.

Patent number: 6249712Abstract: A system for adaptively controlling a wide variety of complex processes, despite changes in process parameters and despite both sudden and systematic drifts in the process, uses response surfaces described by quadratic equations or polynomials of any order. The system estimates the dynamic component of a drifting process or system and thereby identifies the trend of output response variables of the controlled process. Using this information, the system predicts future outputs based on a history of past and present inputs and outputs, thereby recommending the necessary control action or recipe (set of input parameters) to cancel out the drifting trend. A specific embodiment is a system for the adaptive control of photoresist thickness, uniformity, and dispense volume in the spin coating of wafers in integrated circuit manufacturing. Methods used in the adaptive control system are adaptable to control many processes not readily modeled by physical equations.Type: GrantFiled: February 25, 1998Date of Patent: June 19, 2001Inventor: William J. N-O. Boiquaye

Patent number: 6198982Abstract: The presence of particles on the wafer holder of semiconductor exposure equipment is detected by analyzing any up-and-down movement of the stage during the alignment, for exposure, of a wafer mounted on the wafer holder. The analysis of the up-and-down movement of the stage is conducted based on signals from a motor which moves the stage in the vertical (Z-axis) direction, or based on signals from a sensor indicative of the distance that the stage deviates vertically from a reference position. A feedback mechanism produces information representative of the up-and-down movement of the stage, and a computer processes the signals to produce data indicative of whether particles are present beneath the wafer on the stage.Type: GrantFiled: May 26, 1998Date of Patent: March 6, 2001Assignee: Samsung Electronics Co., Ltd.Inventors: Soon-jong Park, Jong-soon Yun
