  • Publication number: 20190214969
    Abstract: A filter includes a series-arm resonator located on a path that connects an input/output terminal (11m) with an input/output terminal (11n), and a first parallel-arm resonant circuit connected between a node, which is located on the path, and ground. The first parallel-arm resonant circuit includes a parallel-arm resonator, and a pair of a capacitor and a switch connected in parallel with each other and in series with the parallel-arm resonator between the parallel-arm resonator and ground. An interconnect line (a1) is connected to the input/output terminal (11m), and an interconnect line (a2) is connected to the input/output terminal. The parallel-arm resonator and the switch are connected by an interconnect line (a3). The interconnect line (a3) has a characteristic impedance lower than a characteristic impedance of the interconnect line (a1) or a characteristic impedance of the interconnect line (a2).

  • Patent number: 10302046
    Abstract: An ozone generator and an internal combustion engine with the ozone generator that can raise ozone additive rate of whole intake air, while suppressing pressure loss in the intake pipe from increasing. The internal combustion engine with an ozone generator includes a tubular intake pipe, through an inner region of which air flows, an ozone generator having an electrode plate that makes ozone and is disposed in the inner region or in the intake pipe, and a limiter that limits the flow of air in the inner region of the intake pipe; the electrode plate has a planar dielectric and high-voltage-side and low-voltage-side electrodes adhered and fixed to the dielectric and is formed in a shape of a plate extending in a direction in which air flows.

  • Patent number: 10283906
    Abstract: Provided are a connector member and a connector that are easy to assemble and capable of adjusting of misalignment or inclination of a fitting axis. In the connector, a first connector member having a first housing is fitted with a second connector member having a second housing and a supporting member that supports the second housing. The first housing is formed with a guide pin, the second housing is formed with a guide-pin guiding part, and the guide-pin guiding part is formed with a guide hole that guides the guide pin. The second housing has a pair of elastic supporting members formed at opposed positions on the supporting member side. When the guide pin is inserted into the guide hole, the guide pin presses the guide hole, the elastic supporting members are elastically deformed, and the second housing is moved, enabling the fitting.

  • Patent number: 10276981
    Abstract: Provided are a connector member and a connector that suppress breakage due to butting, pressing in a fitting direction. In the connector, a first connector member having a first housing is fitted with a second connector member having a second housing and a supporting member having a cylindrical shape that supports the second housing. The second housing has a pair of shaft pins formed at positions opposed to each other on the supporting member side. The supporting member has a support claw including a pair of claw pieces that are elastically deformable and hold each of the shaft pins. After the first connector member and the second connector member are fitted together, when a pressure is applied thereto in a fitting direction, the shaft pins are moved to cause the claw pieces of the support claw to elastically deform, causing the shaft pins to detach from the support claw.

  • Patent number: 10170737
    Abstract: A battery holder includes a first base, a first holding portion and a second holding portion. The first base is opposed to a first end of the battery unit in the state in which the battery unit is located at a first holding position. The first holding portion is movably arranged on the first base between a first position, where the first holding portion contacts a held portion of the battery unit to hold the battery unit at the first holding position, and a second position, where the first holding portion is separated from the held portion. The second holding portion is arranged on the first base at a downstream side of the first holding portion in a removal direction of the battery unit from the battery holder to hold the battery unit at a second holding position that is located at a downstream side of the first holding position.
