  • Patent number: 7082879
    Abstract: The invention is a method of coordinating the movement of a plurality of oppositely directed tramcars operating along a single guidelane. This includes positioning a plurality of fixed stop-boarding areas along the guidelane. By-pass lanes enabling oppositely moving tramcars to pass each other are located in association with at least some of the stop-boarding areas. A predetermined arrival time for each tramcar at each stop-boarding area is calculated such that oppositely moving pairs of tramcars approaching a common stop-boarding area will arrive at approximately the same time. A processor onboard each tramcar calculates the distance and time remaining to the next stop-boarding area. With a known time and distance remaining to the next stop-boarding area, each on-board processor adjusts the speed of the tramcar such that it arrives at approximately the predetermined arrival time.

  • Patent number: 6827021
    Abstract: A specimen conveying system according to the present invention selectively supplies specimens, which are carried in by a specimen carry-in line having conveyor-belt type conveying lane, to a plurality of specimen processing lines each having a conveyor-belt type conveying lane which perform respective specific processes for the specimens. The supply of the specimens to the specimen processing lines is performed using a motor vehicle whose running is controlled by running control means including means for transmitting a command given from a host computer. The configuration of the whole system is simplified to lower the costs, and an operating passage, which crosses the conveying line, is secured to improve the efficiency of the entire specimen processing operation.

  • Patent number: 6721627
    Abstract: A conveyance system which performs conveying action operating carrier vehicles, including a loop track, carrier vehicles which run on the track, a station where each carrier vehicle performs loading and unloading of a cargo, and a standby station for storing the carrier vehicles in a standby state. The number of the carrier vehicles to be used is determined from a conveyance command number, and can be automatically determined in correspondence with the load in the conveyance system. Accordingly, even if the load is not uniform but significantly varied, the conveying action can be conducted readily and efficiently.

  • Patent number: 6418754
    Abstract: A method for heated mold changing at a forming station (24) is performed by apparatus (32) in a heated chamber (22) where heated glass sheets are cyclically formed. A switching station (318) is located adjacent the forming station (24). An unloading station (320) and a mold preheating station (322) are each located adjacent the switching station. An unloading cart (324) is initially movable from the loading station (320) to the switching station (318) and then to the forming station (24) to receive one or more heated molds from the forming station and is subsequently moved from the forming station back through the switching station to the unloading station to permit unloading of each heated mold. A loading cart supports a second mold or a pair of molds for heating within the mold preheating station (322) and is movable from the mold preheating station to the switching station (318) and then to the forming station for mold loading.

  • Patent number: 6363857
    Abstract: A novel transportation system enables passengers to travel at high speeds relative to automobile traffic, while permitting each passenger to individually select his destination, commence travel whenever a transporter is available, and travel with or without his own automobile. The transportation system includes a system of guideways connecting various stations, so that a passenger can travel from an origination station, across guideways, to a destination station of choice. Each guideway consists of parallel tracks supporting support magnets. Each transporter is capable of holding one or more passengers or a single vehicle, with or without passengers. The transporters have horizontally extending supports with transporter support magnets.

  • Patent number: 6360143
    Abstract: A method of controlling a dispensing system, having a robot that moves along a motion segment and applies a material to a workpiece, automatically determines a backup distance for the robot after an error has occurred during the dispensing of a first portion of the material. The backup distance is based on an operational speed of the robot. The robot is relocated to a backup position based on this backup distance to ensure that the robot reaches the operational speed at least by a time that the robot reaches a re-application position. The re-application position is at or near where the application of the first portion of the material ended. Therefore, gaps, overlaps, and puddles in the material on the workpiece are prevented.
