20150020374 | Automatic Assembling System and Method - An automatic assembling system, comprising: a robot performing an operation of inserting a first member into a second member; a force sensor for detecting an insertion force exerted on the first member by the robot; and a controller for controlling the insertion force with a closed-loop feedback control according to a difference between the insertion force detected by the force sensor and a predetermined insertion force, so that the insertion force is less than the predetermined insertion force to protect the first member and/or the second member from damage due to an overlarge insertion force. The present invention also is directed to a method for automatically assembling a product. | 01-22-2015 |
20150021819 | Method of Injecting Sealing Gel Into Recess - A method of injecting a sealing gel into a predetermined structure for a work piece is provided. The method includes the following steps: providing a molding tool with an insertion structure shaped with respect to compliment the predetermined structure, enclosing a local region of a recess of the work piece with the molding tool, injecting a fluid sealing gel into the molding tool, and dismantling the molding tool after the sealing gel has cooled to a solid state. | 01-22-2015 |
20150021825 | Method of Injection Sealing Gel Into a Recess of a Work Piece - A method of injecting a sealing gel into a recess of a work piece, comprising steps of: injecting the sealing gel into the recess and stopping the injection of the sealing gel when the sealing gel reaches a first depth less than the total depth of the recess; after the sealing gel has cooled and solidified, continuing the injection of the sealing gel into the recess and stopping the injection of the sealing gel when the sealing gel reaches another depth higher than the first depth; and repeatedly performing the previous step until the cooled and solidified sealing gel in the recess has a top surface beyond a sealing interface surface of the work piece. | 01-22-2015 |

20150086684 | Method for Preparing and Conditioning Granular Burdock Roots Through Combined Uniform Drying By Using Radio Frequency Pretreatment and Microwave Pulse Spouting - A method for preparing and conditioning granular burdock through combined uniform drying by using radio frequency (RF) pretreatment and microwave pulse spouting is provided. The process of the present disclosure includes performing pretreatment on fresh burdock, protecting color, pre-drying by RF, drying through microwave pulse spouting, and packaging. The color and luster of a product are greatly improved after color protection, the RF pre-drying treatment may be performed for 20 minutes, and hot air drying treatments for removing moisture on the surface may be performed for 60 minutes. The method has a short drying time and high efficiency. The sectional microwave pulse spouting treatment needs 60 minutes totally, while the complete hot air drying treatment needs 400 minutes. Therefore the drying time of the method is greatly shortened, and the drying is uniform, and a sample after microwave pulse spouting drying has strong fragrance. | 03-26-2015 |
