  • Publication number: 20240120247
    Abstract: A method of manufacturing a semiconductor package is provided, with an integrated heatsink and electrical connection feature. The semiconductor die can be attached to the terminal using eutectic bonding, preferably CuSn eutectic, Ag containing adhesives or Ag sintering material. These bondings are lead (Pb) free connection methods, which make the finished semiconductor package RoHS compliant (restriction of hazardous materials).

  • Publication number: 20240041137
    Abstract: The present disclosure provides a physiological bra with automatic volume adjustment, including: a bra body, a cup structure overlapping the bra body, and a lining structure overlapping the cup structure, where the cup structure is arranged between the bra body and the lining structure; top portions of two sides of the bra body, top portions of two sides of the cup structure and top portions of two sides of the lining structure are fixedly connected; and the cup structure is stretchable between the bra body and the lining structure to vary the volume of the lining structure. The present disclosure solves the problem that existing bras cannot meet the needs of people with breast asymmetry.

  • Patent number: 7189074
    Abstract: The co-combustion process may comprise the following unit operations: routing of hot gas (10) generated in the clinker cooling process to a rotary kiln (1); use of part of the rotary kiln exhaust gas to dry solid wastes in rotary dryers; leading the gases from both the dryer and the combustion kiln to the secondary combustion chamber (2); use of additional fuel to boost up the secondary combustion chamber reaction temperature to as high as 1200° C.; primary dry gas scrubbing in a precalciner or precalciners (3, 3a); heat recovery (4) and power generation; secondary gas scrubbing (5) in a semi-dry scrubber; bag filtering after activated carbon injection and returning of all the collected ash and used carbon into the waste kiln and/or a cement kiln. Detrimental materials for cement processing generated by waste combustion can be by-passed to a scrubbing system and a cement kiln. Residue slag from waste kilns can be treated and reused.
