  • Publication number: 20200203162
    Abstract: A method for fabricating an ultra-thin graphite film on a silicon carbide substrate includes the steps of: (A) providing a polyamic acid solution and a siloxane-containing coupling agent for polymerizing under an inert gas atmosphere to form a siloxane-coupling-group-containing polyamic acid solution; (B) performing a curing process after applying the siloxane-coupling-group-containing polyamic acid solution to a silicon carbide substrate; (C) placing the silicon carbide substrate in a graphite crucible before placing the graphite crucible in a reaction furnace to perform a carbonization process under an inert gas atmosphere; (D) subjecting the silicon carbide substrate to a graphitization process to obtain a graphite film, thereby make it possible to fabricate an ultra-thin graphite film of high-quality on the surface of silicon carbide in a lower graphitization temperature range.

  • Publication number: 20190330376
    Abstract: A recombinant protein drug includes a parent protein drug coupled with a modified kininogen-1 peptide. The modified kininogen-1 peptide has the sequence of SEQ ID NO:2 or a homolog having a sequence identity of 80% or higher. The parent protein drug is a bispecific antibody having a first targeting domain linked by a bridging domain with a second targeting domain. The modified kininogen-1 peptide is fused between the first targeting domain and the bridging domain, or between the bridging domain and the second targeting domain. A method for increasing the serum half-life of a protein drug includes constructing a fusion protein comprising the protein drug coupled with a modified kininogen-1 peptide.

  • Patent number: 8466729
    Abstract: A delay cell includes a first inverted transistor pair, a second inverted transistor pair and a plurality of delay units. The first inverted transistor pair is used to receive an input signal. The second inverted transistor pair is electrically cross-coupled to the first inverted transistor pair and cross-controlled by the first inverted transistor pair. The delay units are cascaded between the first inverted transistor pair and between the second inverted transistor pair, thereby providing a plurality of signal propagation delays sequentially, wherein the input signal is delayed for a pre-determined time by the first inverted transistor pair, the second inverted transistor pair and the delay units which are operated sequentially, thereby creating an output signal corresponding to the pre-determined time. A digitally controlled oscillator including the aforementioned delay cells is provided.
