  • Publication number: 20220329323
    Abstract: An optical emitting device includes a base, a thermoelectric cooler, an optical communication assembly and a circuit board. The base includes a main body and a stem connected with each other. The stem extends from a basal surface of the main body, and a normal of a supporting surface of the stem is non-parallel to a normal of the basal surface of the main body. The thermoelectric cooler is disposed on the supporting surface of the stem. The optical communication assembly is disposed on the thermoelectric cooler, and the thermoelectric cooler is between the optical communication assembly and the stem. The circuit board is disposed on the base and passes through the main body and electrically connected with the optical communication assembly.

  • Patent number: 10816433
    Abstract: A leakage inspection method and leakage inspection device for container to be inspected are provided. When a container to be inspected having a deformable flexible part is to be inspected for leakage, the container to be inspected is filled with an inspection gas containing helium, the container to be inspected, which has been filled with the inspection gas, is disposed in an inspection chamber partitioned from the outside, and an upward flow of a carrier gas is formed from the lower part to the upper part of the container to be inspected. A leakage of the inspection gas filled in the container to be inspected is then detected on the basis of the result of measuring the concentration of helium in the carrier gas collected at a position higher than a position where the carrier gas is fed into the inspection chamber.
