  • Patent number: 11851236
    Abstract: A pipe connectable plastic bucket includes a bucket and at least two quick-connect devices. The bucket has a plurality of through holes for communication between the inside and the outside of the bucket. The at least two quick-connect devices respectively correspond to the plurality of through holes, and are disposed on the bucket. The at least two quick-connect devices are adapted to connect to pipes, and are used for allowing a fluid entering and exiting the bucket through the plurality of the through holes. The at least two quick-connect devices comprise a first quick-connect device for allowing the liquid to enter and to exit the bucket. The present invention also provides a method of using the pipe connectable plastic bucket.

  • Publication number: 20210223699
    Abstract: A method of removing a photoresist, a laminate, a method of forming a metallic pattern, a polyimide resin, and a stripper are provided. The method of removing the photoresist includes forming a release layer on a substrate, the release layer having a first surface and a second surface opposite to each other, wherein the first surface of the release layer is in contact with the substrate; forming a photoresist layer on the second surface of the release layer; and removing the release layer and the photoresist layer. The release layer is formed by a polyimide resin. The polyimide resin is obtained by performing a polymerization of tetracarboxylic dianhydrides, diamines, and phenolamines. The diamines include hydroxyfluorinated diamines, benzoic acid diamines, and aminotetramethyldisiloxanes.
