  • Publication number: 20200123630
    Abstract: A process for producing dual phase steel sheet including steps of making a liquid steel having a chemical composition in wt % of C: 0.03-0.12. Mn: 0.8-1.5. Si: <0.1, Cr: 0.3-0.7, S: 0.008 maximum, P: 0.025 maximum, Al: 0.01 to 0.1, N: 0.007 maximum. Nb: 0.005-0.035. and V: 0.06 maximum, remainder Fe; continuous casting the liquid steel into a slab; hot rolling the slab into a hot rolled sheet at finish rolling temperature (FRT) 840±30 ° C.; cooling the hot rolled sheet on the run out table at a cooling rate 40 ?70° C./s to an intermediate temperature (Tint) of 720° C.?Tint?650° C.; natural cooling the hot rolled sheet for a duration of 5-7 seconds and rapidly cooling the hot rolled sheet to transform remaining carbon enriched austenite to martensite, at cooling rate of 40-70 ° C./s to a coiling temperature below 400° C.

  • Patent number: 10541680
    Abstract: The disclosure provides a flip-flop. The flip-flop includes a master latch. The master latch receives a flip-flop input, a clock input, an inverted clock input, an enable signal and an inverted enable signal. A slave latch is coupled to the master latch and receives the enable signal and the inverted enable signal. An output inverter is coupled to the slave latch and generates a flip-flop output.

  • Patent number: 9646123
    Abstract: The disclosure provides a standard cell. The standard cell includes a first PMOS transistor and a second PMOS transistor whose gate terminal respectively receives a first input and a second input. A drain terminal of each of the first PMOS transistor and the second PMOS transistor is coupled to a first node. The standard cell further includes a first NMOS transistor and a third NMOS transistor whose gate terminal respectively receive the first input and the second input. A drain terminal of each of the first NMOS transistor and the third NMOS transistor is coupled to the first node. The first NMOS transistor is coupled to a second NMOS transistor, and the third NMOS transistor is coupled to a fourth NMOS transistor. A gate terminal of the second NMOS transistor and the fourth NMOS transistor respectively receives the second input and the first input.

  • Publication number: 20110017494
    Abstract: Provided are compositions that include a dielectric matrix material defining multiple voids of substantially uniform respective dimension and configured as a substantially uniform array. The voids may be configured such that charges that accumulate at surfaces of at least some of the voids when the composition is immersed in a uniform external electric field interact with charges that accumulate at surfaces of at least others of the voids to cause movement of the respective charges in a direction having a component transverse to the electric field. Hollow particles may be disposed within respective voids of the array of voids defined by the matrix material, and particles, such as, for example, ceramic, varistor, and/or inorganic dielectric particles, may be incorporated within the matrix material. Associated devices are also provided.
