Publication number: 20080191848Abstract: When a detector sensor such as an infrared sensor or the like detects a palette or cart mounting a product, the output of the radio wave from the antenna of the reader/writer is set to a minimum value. Then, the radio wave output value is gradually increased from the minimum value until an RFID tag can be read/written. After the RFID tag can be read/written, a target process such as the reading/writing of the RFID tag or the like is performed and the process is terminated. After the process is terminated, the radio wave output is returned to the minimum value.Type: ApplicationFiled: December 31, 2007Publication date: August 14, 2008Inventors: Shuko SAITO, Hidehiko FUCHIDA, Tomohiko MAEDA, Yoshitaka MURAOKA, Kazuo SATO

Publication number: 20060271217Abstract: A device to support studies of the positions in which parts necessary for assembly are placed and the positions in which assembly tasks are performed. A manufacturing study support device has a computation portion, a display portion which displays animations, and a storage portion which stores part animation data comprising three-dimensional shapes of parts, part storage positions which are three-dimensional coordinate data of positions at which the parts are stored, and assembly starting positions which are three-dimensional coordinate data of positions from which assembly tasks using the parts are started. The computation portion calculates part supply animation paths, taking the part storage positions as starting points and the assembly starting positions as ending points, and based on the part animation data and part supply animation paths, causes the display portion to display movement of the parts.Type: ApplicationFiled: August 30, 2005Publication date: November 30, 2006Applicant: FUJITSU LIMITEDInventors: Kaname Suzuki, Kenji Hasegawa, Masahiko Yamada, Koji Yoshioka, Yoshitaka Muraoka
