  • Patent number: 9975331
    Abstract: An inkjet printer comprising a plurality of nozzles, a plurality of pressure chambers, a plurality of diaphragms, a plurality of piezoelectric elements, and a controller. Each of the plurality of diaphragms is deflected between a first state and a second state. The controller is configured to control voltage application to each of the plurality of piezoelectric elements. When a diaphragm is in the first state, the controller applies a first voltage so that the diaphragm is substantially flat; and when the diaphragm is in the second state, the controller applies a second voltage. The controller is configured to control the voltage such that a pressure chamber ejects an ink droplet from the corresponding nozzle in response to the deflection of the diaphragm reverting from the second state to the first state.

  • Publication number: 20180115061
    Abstract: An antenna-integrated wireless module is provided which does not need a metal case, and which can realize size reduction. A shield layer is formed on an upper surface of a resin sealing layer, which is disposed on one principal surface of a substrate and which covers a wireless region and an antenna region, such that the shield layer does not cover a portion of the resin sealing layer, the portion being positioned directly above the antenna region. Hence the shield layer formed on the upper surface of the resin sealing layer on the side covering the wireless region can serve to suppress electromagnetic waves radiated from a wireless functional section, which is disposed in a region overlapping the wireless region when looking at the module in a plan view, and which includes an RF circuit disposed at least on the one principal surface of the substrate or inside the substrate.
