  • Patent number: 9824827
    Abstract: The instant disclosure relates to a method for making solid electrolytic capacitor package structure with improved conductive terminals. The first step is to provide at least one conductive terminal having an electrical contact portion and a lead-out portion. The next step is to remove a portion of mantle layer from the surface of the core layer of at least one conductive terminal by a dry-type process. The next step is to sequentially stack together a plurality of stacked-type capacitors to form a capacitor unit and then electrically connect the capacitor unit to at least one conductive terminal. The next step is to form a package body to encapsulate the capacitor unit and the electrical contact portion of at least one conductive terminal. The last step is to bend the lead-out portion of at least one conductive terminal to an axis that extends along the surface of the package body.

  • Patent number: 7943676
    Abstract: A method of recycling waste plastic foam materials firstly is to smash a waste material including polyurethane foam into fine particles so as to obtain a first starting material. The first starting material is then crisped and followingly milled into powder so as to obtain a second starting material. The second starting material is then placed into a mixer to mix with a first foaming reaction solution including polyol, catalyst and additives injected into the mixer so as to form a semi-treated foaming material. And then, the semi-treated foaming material is mixed with a second foaming reaction solution including diisocyanate injected into the mixer so as to obtain a completed-treated foaming material. Lastly, the completed-treated foaming material is poured into a mold and then water vapor is uniformly introduced into the mold so as to induce the completed-treated foaming material to proceed foaming reaction.
