  • Publication number: 20200269986
    Abstract: To provide an air conditioning piping structure for an aircraft which can promote mixing of temperature adjusted air and recirculated air flowing into a mixing chamber forming an air conditioning system. An air conditioning piping structure causes temperature adjusted air obtained by an air conditioning apparatus of an aircraft and recirculated air discharged from a pressurized compartment to flow into a mixing chamber which mixes the temperature adjusted air and the recirculated air. This air conditioning piping structure includes a first pipe through which the temperature adjusted air flows, a second pipe through which the recirculated air flows, and which is connected to the first pipe, and a flow passage restricting part configured to apply a resistance to at least one of the temperature adjusted air and the recirculated air in a vicinity of a merging position where the temperature adjusted air and the recirculated air are merged.

  • Publication number: 20200231287
    Abstract: An air-conditioning duct structure of an aircraft includes an air-conditioning duct that is provided on each of a starboard side and a port side and guides conditioned air to a vicinity of a ceiling of a cabin in the aircraft. The air-conditioning duct includes a blowout portion and a blowout upstream portion. The blowout portion blows out the conditioned air to the cabin from an outboard side of the ceiling to an inboard side of the ceiling and toward a lower part than the ceiling, and the blowout upstream portion communicates with an upstream side of the blowout portion. In addition, the blowout portion or the blowout upstream portion is curved to cause a terminal end side of the blowout portion to be inclined downward with respect to a horizontal direction.

  • Publication number: 20200094996
    Abstract: Provided is a multilayer heat-insulating material which reduces a deterioration in heat-insulating performance at the periphery of a mounting means for mounting on a mounting subject and which facilitates deformation into a desired shape. This multilayer heat-insulating material comprises a heat-insulating member (2) in which heat-insulating sheets (2a) and spacers (2b) are laminated, an engagement sheet (3) provided adjacent to the heat-insulating member (2), heat-insulating member engagement fixtures (5) for penetrating through and engaging the heat-insulating member (2) and the engagement sheet (3), and a mounting member (4) that is provided on the engagement sheet (3) and that can be removably attached to a mounting subject (9). Engagement of the heat-insulating member engagement fixtures (5) is such that the layers of the heat-insulating member (2) do not adhere to each other.

  • Publication number: 20190300009
    Abstract: A vehicle control device capable of improving safety, even when abnormality in the operation of an arithmetic processing unit occurs. A second microcomputer receives trajectory information transmitted from a first microcomputer via a communication line and calculates control commands to actuators to synchronize the arithmetic processing unit allowing the first and second microcomputers to be synchronized. The second microcomputer performs a calculation and compares the result with the calculation result of the first microcomputer so that the second microcomputer can accurately determine whether or not the first microcomputer is abnormal. When the abnormality occurs in the first microcomputer based on the determination, the actuators are controlled by switching to the control commands calculated by the second microcomputer which is synchronized with the arithmetic processing unit. Thus, the device performs seamless self-driving control without the occurrence of abrupt control gaps.

  • Patent number: 10386231
    Abstract: A carbon isotope analyzer 1 includes a carbon dioxide isotope generator 40 that includes a combustion unit that generates gas containing carbon dioxide isotope from carbon isotope, and a carbon dioxide isotope purifying unit; a spectrometer 10 including an optical resonator 11 having a pair of mirrors 12, and a photodetector 15 that determines the intensity of light transmitted from the optical resonator 11; and a light generator 20 including a light source 23, a first optical fiber 21 to transmit a light beam from the light source 23, a second optical fiber 22 for wavelength conversion, the second optical fiber 22 splitting from the first optical fiber 21 at a point and combining with the first optical fiber 21 at another point downstream of the splitting point, and a non-linear optical crystal 25 that generates light having the absorption wavelength of the carbon dioxide isotope on the basis of the difference in frequency between light beams transmitted through the optical crystal 25.
