  • Publication number: 20240101093
    Abstract: A vehicle brake system includes a switching valve switchable between a first state allowing communication between a first fluid pressure generating device and a frictional brake and a second state allowing communication between a second fluid pressure generating device and the frictional brake. The second fluid pressure generating device generates a fluid pressure by moving a piston with an electric actuator, and has a fluid pressure supply port connected to the switching valve and an atmosphere opening port connected to a reservoir tank. When, due to a failure, the switching valve becomes a third state in which the switching valve makes each of the first fluid pressure generating device and the second fluid pressure generating device communicate with the frictional brake, a control device controls the second fluid pressure generating device to close the atmosphere opening port with the piston.

  • Patent number: 11799421
    Abstract: This inspection system for a concentrator photovoltaic apparatus includes: a module; a tracking mount configured to track the sun, the tracking mount having mounted thereto an array formed by assembling a plurality of the modules; an inverter apparatus to extract a direct-current power generated by the array, convert the direct-current power into an alternating-current power, and output the alternating-current power; and an imaging apparatus being positioned between the sun and the array tracking the sun, the imaging apparatus taking an image of the array from a direction orthogonal to a surface of the array. While the array is tracking the sun and is causing sunlight to be concentrated on the cell, the inverter apparatus produces a state where extraction of a power from the array is restricted, to cause the cell to spontaneously emit light, and the imaging apparatus takes an image of the emitted light of the cell.

  • Publication number: 20230314756
    Abstract: Provided are a camera device and a portable electronic device. The drive magnet is arranged closer to the optical axis, and the drive coil is arranged between a closed magnetic circuit formed by the drive magnet and a case. In this case, there is no need to provide a yoke at the case, and a gap between the drive magnet and the drive coil can be made closer, thereby improving the driving force of the automatic focusing mechanism and reducing a volume of the drive element of the automatic focusing mechanism. Meanwhile, it can prevent the movable part from contacting a surface of the magnet, thereby improving the dust-proof performance. In addition, by making the drive coil, which serves as a heat source, move away from the lens, degradation of the lens performance caused by heat can be alleviated.
