  • Publication number: 20200406327
    Abstract: A metal blank is clamped between upper and lower binders with the metal blank engaging against a protrusion extending from a binder surface of any of the upper binder, the lower binder, and both upper and lower binders, to create a binder gap between the metal blank and the binder surface adjacent the protrusion. The binder gap prevents cooperating springback control binder elements of the binder surface from actively engaging the metal blank. The metal blank is drawn into a cavity, with the protrusion riding on the metal blank until the protrusion falls off an edge of the metal blank, which closes the binder gap between the metal blank and the binder surface causing the cooperating springback control binder elements to actively engage the blank for the post-forming stretching operation.

  • Publication number: 20200391326
    Abstract: Segment openings are formed in a metal sheet separated by uncut sections at a first processing station, which define an inner blank portion of the metal flow opening. At a second processing station, the uncut sections and the inner blank portion initially transfer stress around the segment openings and across the interior flow opening during a forming operation. During the forming operation, a protrusion of one mold member contacts a first side of the inner blank portion of the interior flow opening. In addition, another mold member is contact the opposite side of the metal sheet so that the mold members cooperate to separate all but one of the uncut sections by which the inner blank portion remains attached to the metal sheet. In this way, the interior metal flow opening is completed without piercing the metal sheet at the second processing station during the forming operation.

  • Patent number: 10826534
    Abstract: An encoding method, an encoder, and a decoder for dynamic power consumption control are provided. The encoder includes a control unit, an initial encoding unit, and L incremental encoding units. The control unit is configured to enable only the initial encoding unit in an RS (N0, K) operating mode to perform encoding or enable only the initial encoding unit and first j incremental encoding units in the L incremental encoding units in an RS (Nj, K) operating mode to perform encoding. The initial encoding unit is configured to perform RS FEC encoding on m(x) to obtain a quotient D0(x) and a remainder R0(x) of xN0?Km(x) relative to g0(x). An (h+1)th incremental encoding unit is configured to obtain, according to a quotient Dh(x) and a remainder Rh(x), a quotient Dh+1(x) and a remainder Rh+1(x) of xNh+1?Km(x) relative to gh+1(x).

  • Publication number: 20200261588
    Abstract: Disclosed are an intermediate drug having synergistic anticancer activity and a polyethylene glycol-coupled synergistic anticancer drug, and a method preparing therefor and use thereof. The intermediate drug has the general structural formula of (I), and the polyethylene glycol-coupled synergistic anticancer drug has the general structural formula of (II). The drugs achieve the combined medication of various anticancer drugs and avoid the toxic reaction caused by the interaction among the drugs or by the pharmacokinetics of the drugs when taking various anticancer drugs, facilitate overcoming the multidrug resistance of cancers, have a synergistic effect, and can be used for preparing anticancer medicaments and for treating cancers.
