    摘要: A method of forming a compound semiconductor device. The method includes the steps of depositing a film that contains zinc oxide and silicon oxide to contain the zinc oxide by 70 wt % or more on compound semiconductor layer as a diffusion source, and diffusing zinc from the diffusion source into the compound semiconductor layer by annealing. Accordingly, there can be provided a compound semiconductor device manufacturing method containing the step of diffusing zinc into compound semiconductor layers, capable of deepening a Zn diffusion position from a ZnO/SiO2 film to such extent that COD endurance of laser end face window structures can be increased rather than the prior art.

    摘要: A semiconductor laser includes a substrate having a (100) face as its main surface, where the substrate has a stripe of a first mesa extending in a direction of the substrate and including a (111)B face as its sloping surface, a buried layer formed on the substrate excluding a top surface of the stripe of the first mesa so that the (111)B face of the stripe of the first mesa is covered a sloping surface part of the buried layer, where the top surface of the stripe of the first mesa is the (100) face of the substrate and forms a stripe of a second mesa together with the sloping surface of the buried layer and the stripe of the second mesa has a smaller inclination than the stripe of the first mesa, and a double heterostructure made up of a plurality of semiconductor layers and formed on the stripe of the second mesa. The double heterostructure has a substantially trapezoidal cross section which is determined by the stripe of the second mesa.

    摘要: There is provided an automatic choke apparatus for an engine. A bimetal that is coupled to a choke valve of an intake system is provided in the vicinity of an outer wall face of a muffler. The muffler is divided into a first expansion chamber and a second expansion chamber across a partition plate. An exhaust hole that allows the expansion chambers to be communicated with each other is formed at the lower part of the partition plate. An exhaust gas is guided from the upstream first expansion chamber toward the downstream second expansion chamber through the exhaust hole. A bypass hole is formed at an upper part of the partition plate in such a manner that that the expansion chambers are communicated with each other as bypassing the exhaust hole. The bypass hole is open to the vicinity of the outer wall face opposite to the bimetal.
