  • Publication number: 20200204172
    Abstract: A low-power-consumption high-speed zero-current switch includes a delay controller, a driving stage and a power transistor MN, wherein: an input of the delay controller is connected with an external clock CLK, an output of the delay controller is connected with an input of the driving stage, and an output of the driving stage is connected with a gate of the power transistor MN; the delay controller includes a gate signal generator, a sampling circuit and a current controller, and three of which form a negative feedback loop for stabilizing the turn-on voltage VON and the turn-off voltage VD to 0, so that when the power transistor MN is turned on or off, the source-drain voltage thereof is 0. The present invention no longer uses a high-power-consumption high-speed comparator, but uses a low-power-consumption delay controller to generate turn-on and turn-off signals of the power transistor.

  • Publication number: 20200198013
    Abstract: The present invention provides a method to achieve full densification and grain size control for sintering metal materials. First, raw material powder is deagglomerated to obtain deagglomerated powder with dispersion. The deagglomerated powder is granulated by spray granulation. The granulated particles are processed by high-pressure die pressing and cold isostatic pressing. The powder compact is sintered by two-step pressureless sintering. The first step is to heat up the powder compact to a higher temperature and hold for a short time to obtain 75-85% theoretical density; the second step is to cool down powder compact to a lower temperature and hold for a long time. The two-step sintering can decrease the sintering temperature, so that the powder compact can be densified at a lower temperature. Thus, the obtained refractory metal product is densified, with ultrafine grains, uniform grain size distribution, and outstanding mechanical properties.

  • Publication number: 20200201908
    Abstract: The disclosed embodiments provide a system for processing data. During operation, the system applies a first set of hash functions to a first entity identifier (ID) for a first entity to generate a first set of hash values. Next, the system produces a first set of intermediate vectors from the first set of hash values and a first set of lookup tables by matching each hash value in the first set of hash values to an entry in a corresponding lookup table in the first set of lookup tables. The system then performs an element-wise aggregation of the first set of intermediate vectors to produce a first embedding. Finally, the system outputs the first embedding for use by a machine learning model.
