  • Patent number: 10590261
    Abstract: An interlayer comprised of a thermoplastic resin, varying amounts of an epoxidized vegetable oil, and, optionally, a conventional plasticizer. The use of a thermoplastic resin, an epoxidized vegetable (plant) oil, and, optionally, a conventional plasticizer creates synergy allowing the flow of the interlayer to be increased without sacrificing other characteristics typically associated with an increased flow (e.g., increased blocking and creep, exudation, surface roughness formation, decreased mechanical strength, and decreased manufacturing capability). In this regard, the epoxidized vegetable oil acts as a flow improvement agent, resulting in a high-flow interlayer. As a result, a thinner interlayer can be utilized in forming multiple layer panels because the resulting thinner interlayer has improved flow properties.

  • Publication number: 20200076347
    Abstract: A circuit for actively performing short-circuit and a motor controller are provided. The circuit includes an undervoltage detecting circuit, an emergency power supply, a reverse-flow preventing circuit, and a gate level selecting switch. The undervoltage detecting circuit is configured to detect a driving power supply signal outputted from the driving power supply and output, in a case that an amplitude of the driving power supply signal is lower than a first threshold, an emergency active short-circuit enable signal. In response to the emergency active short-circuit enable signal, the emergency power supply is enabled and the gate level selecting switch is controlled to switch from a first conduction path to a second conduction path, to transmit an emergency power supply signal outputted from the emergency power supply to a bridge arm via the second conduction path.
