    摘要： The applications and medical devices of Midkine in the field of biotechnology are described in this invention. This invention describes the applications of the protein as follow in (a) or (b) in preparing drugs for promoting cartilage growth or treating cartilage diseases, the protein as a growth factor for promoting chondrocyte proliferation, or medical devices containing this protein: (a) the protein whose amino acid sequence is shown as SEQ ID NO.1; (b) the proteins whose amino acid sequence have at least 60% homology comparing with amino acid sequence described in (a). The present invention is different from the present knowledge of MK and its related proteins. The experimental results demonstrated that MK promotes proliferation of three types of chondrocytes and is used for preparing drugs for treating cartilage disease. It may provide new therapy for treating cartilage diseases clinically, and new technology for expansion of chondrocytes in vitro for cartilage tissue engineering.

    摘要： A DC to DC converter includes a control circuit, a gate driver circuit, and a power stage circuit. The control circuit receives and compares a DC output voltage. When the DC output voltage lower than a first threshold voltage, a PWM signal with a first frequency is outputted, and when the DC output voltage higher than the first threshold voltage, the PWM signal with a second frequency is outputted. The second frequency is higher than the first frequency. The gate driver circuit receives the PWM signal and converts the PWM signal to a first driving signal and a second driving signal. The power stage circuit converts a DC input voltage to the DC output voltage according to the first driving signal and the second driving signal.

    摘要： In one embodiment of the invention, an integrated circuit such as a programmable logic device includes volatile memory, nonvolatile memory, and a data shift register for reading data from the nonvolatile memory and for reading data from and writing data to the volatile memory. A built in self test (BIST) circuit is operable to test the nonvolatile memory without the data shift register reading data from the nonvolatile memory. The BIST circuit may include a finite state machine for performing at least one of the following tests on the nonvolatile memory: bulk erase, bulk program; margin bulk program; and/or margin bulk erase. A memory controller responsive to the finite state machine is operable to write data to and read data from the nonvolatile memory during testing of the nonvolatile memory.
