  • Patent number: 10864586
    Abstract: An electrochemical machining device includes a plurality of electrodes, a guiding member and a plate member. The electrodes are disposed around a workpiece. The guiding member is configured to limit and guide each of the electrodes to move. The plate member is configured to exert a force to each of the electrodes. The driving member is configured to rotate the workpiece. The plate member is connected to each of the electrodes. A force-exerting direction of the force from the plate member to each of the electrodes is parallel to a central axis of each of the electrodes or deflects off the central axis. Each of the electrodes is passed through the guiding member and configured to perform a machining on the workpiece which is rotated by the driving member, and each of the electrodes has an electrochemical machining direction which is perpendicular, oblique or parallel to the workpiece.

  • Patent number: 10737341
    Abstract: The present disclosure provides an electrochemical machining apparatus including a pressurized tank, a cap, a stabilizing plate, a guiding element, and an electrode. The pressurizing tank has a top surface and a chamber, wherein the top surface is disposed with an opening and a limiting portion. The cap fits in the opening and is limited by the limiting portion to seal the pressurized tank. The stabilizing plate is spaced from the top surface or the cap by a distance. The guiding element penetrates the stabilizing plate to connect with the cap and provides a channel to the chamber. The electrode is guided by the guiding element and penetrates the chamber via the channel. When the electrode processes a workpiece in the chamber during an electrochemical machining operation, the cap takes a pressure generated during the electrochemical machining operation, and the stabilizing plate stabilizes the electrode and the guiding element.

  • Patent number: 10015980
    Abstract: A method includes a step of identifying a subject in need of diet modification; and administering a first diet to the subject for a first time period. The first diet provides 4.5 to 7 kilocalories per pound of subject for a first day and 3 to 5 kilocalories per pound of subject per day for a second to fifth day of the first diet. The first diet includes less than 30 g of sugar on the first day; less than 20 g of sugar on the second to fifth days; less than 28 g of proteins on the first day; less than 18 g of proteins on days the second to fifth days; 20 to 30 grams of monounsaturated fats on the first day; 10 to 15 grams of monounsaturated fats on the second to fifth days; and between 6 and 10 grams of polyunsaturated fats on the first day.
