Latest Patents
One of Ebisawa's latest patents is a production managing method for photo film production. This method involves slitting a film web to create continuous photo film of a predetermined width. Production managing information is recorded on an RFID tag, which includes essential details such as roll number and slitting number. This information is crucial for tracking the production process and identifying defects in the motion picture photo film. If a defect is detected, the production managing information can be referenced to trace the source of the issue.
Another significant patent by Ebisawa is a numerically controlled tape takeup system featuring a device for automatic tension control. This system utilizes a tensiometer to measure the tension applied to the tape. The output from the tensiometer is converted into a tension value, which is then used to control the rotational torque of the takeup reel. This ensures that the tension applied to the tape remains consistent and converges on a target value, enhancing the overall efficiency of the tape takeup process.
