  • Publication number: 20240178160
    Abstract: A package structure and an electronic apparatus includes a power semiconductor device, a wire, and a shape memory object. The wire is electrically connected to the power semiconductor device, the shape memory object is in contact with the wire, and the shape memory object is configured to deform when temperature of the shape memory object is not less than preset temperature, to enable a current in the wire to be cut off or reduced. In this way, impact of high temperature generated by the power semiconductor device when an overcurrent occurs in the power semiconductor device on the printed circuit board is reduced, a possibility that a printed circuit board is damaged is greatly reduced, and an overcurrent self-protection capability of the package structure is implemented.

  • Patent number: 9520942
    Abstract: The present disclosure provides a millimeter-wave waveguide communication system. The millimeter-wave waveguide communication system may comprise: a clock component, and at least two sets of millimeter-wave receiving/transmitting channels. The clock component is configured to provide a clock signal to sending ends and receiving ends of the two sets of millimeter-wave receiving/sending channels respectively. Each set of millimeter-wave receiving/sending channels comprises: a transmitter component, a receiver component and a transmission waveguide. The transmission waveguide is located between the transmitter component and the receiver component and is configured to provide a channel for millimeter-wave transmission. The top face, side face and/or bottom face of the transmission waveguide, except for active devices and accessories thereof, are plated with a metal conductive wall to form an electromagnetic shield from a transmission waveguide in an adjacent millimeter-wave receiving/sending channel.

  • Publication number: 20060081483
    Abstract: This invention relates to a new kind of hydrogen storage mixture and container thereof. This hydrogen storage container consists of a container casing, a hydrogen storage mixture and a valve. The hydrogen storage mixture loaded inside the container is made of hydrogen storage alloy granules and metal fibers and/or non-hydrogen-absorbing alloy fibers that do not absorb hydrogen. The non-hydrogen-absorbing fibers are dispersed among the hydrogen storage alloy granules and form a network structure. The non-hydrogen-absorbing fibers include non-hydrogen-absorbing metal fibers and/or non-hydrogen-absorbing alloy fibers, or their mixture. In the hydrogen storage mixture, the weight ratio of the non-hydrogen-absorbing fibers to the hydrogen storage alloys is about 0.01˜0.1.
