  • Publication number: 20210396323
    Abstract: A ventilation component (1a) is to be attached to a housing (2) at a ventilation opening (5). The ventilation component (1a) includes a gas-permeable membrane (10), a ventilation valve (20), and a structural member (30). The structural member (30) has an inner space (40), and at least one of a first ventilation path (51) and a second ventilation paths (52). The inner space (40) is a space accommodating the gas-permeable membrane (10) and/or the ventilation valve (20). The first ventilation path (51) allows the inner space (40) to communicate with an external space of the ventilation component (1a). The first ventilation path (51) has a first inner opening (51i) and a first outer opening (51e), and the first inner opening (51i) faces the first outer opening (51e). The first inner opening (51i) and the first outer opening (51e) are present along a plane parallel to an outer surface (2s) of the housing.

  • Publication number: 20210396324
    Abstract: A ventilation component (1) includes a gas-permeable membrane (10), a ventilation valve (20), and a structural member (30). The ventilation component (1) is to be attached to a housing (2) having a ventilation opening (5). The ventilation valve (20) includes an elastic body, and is opened and closed by elastic deformation of the elastic body. The structural member (30) supports the gas-permeable membrane (10) and the ventilation valve (20). In an attached state where the ventilation component (1) is attached to the housing (2), ventilation between an inside of the housing (2) and an outside of the housing (2) is carried out via the gas-permeable membrane (10), and the ventilation valve (20) is opened to discharge a gas inside the housing 2 to the outside of the housing 2 when a difference between a pressure inside the housing (2) and a pressure outside the housing (2) is equal to or higher than a predetermined value.

  • Patent number: 11176073
    Abstract: A data processing apparatus includes a power-source controller, a data processing device, a physical-layer section, a communication controller, and a state controller. The power-source controller controls a first power-source setting and a second power-source setting. The second power-source setting causes less electric power consumption than the first power-source setting. The communication controller performs the communication with the data processing device through a predetermined communication path and the physical-layer section under the first power-source setting. The communication controller stops the communication with the data processing device through the communication path and the physical-layer section under the second power-source setting. The state controller maintains the second communication state with respect to the data processing device side of the communication path while electric power supply to the physical-layer section is reduced under the second power-source setting.

  • Publication number: 20210223726
    Abstract: A load controller includes a control device, a switching device, an arc suppression circuit, and a control section. The control device is provided on an electric power supply path between first and second terminals coupled to an alternating-current electric power source, and controls electric power supply to a load provided on the electric power supply path. The switching device is provided on the electric power supply path and is to be in an open state or a closed state. The arc suppression circuit is to suppress discharge at the switching device. The arc suppression circuit is to be set to an enabled state or a limited state. The control section controls operation of the control device, the switching device, and the arc suppression circuit. The control section varies the arc suppression circuit from the limited state to the enabled state after bringing the switching device into the closed state.

  • Patent number: 10096297
    Abstract: For each unit transmission block having a pixel data block including at least one pixel data piece, clock data is added contiguously to a head of the pixel data block. If no data transition has occurred at a boundary between the clock data and the pixel data block, logic inversion is performed on the pixel data piece. Thereafter, a transmission image data signal in which unit transmission blocks, each constituted by adding an inversion flag immediately before the clock data, are consecutively arranged is transmitted to a display panel driver. The driver generates a clock signal on the basis of the clock data included in the received signal and takes in the pixel data piece or the resultant obtained by inverting the logic level of this pixel data piece in accordance with the clock signal on the basis of the inversion flag.
