    • A light emitting device chip is obtained by dicing a light emitting device wafer having a light emitting layer section 24 based on a double heterostructure in which a first-conductivity-type cladding layer 6, an active layer 5 and an second-conductivity-type cladding layer 4, each of which being composed of a compound semiconductor having a composition allowing lattice matching with GaAs, out of compound semiconductors expressed by formula (AlxGa1-x)yIn1-yP (where, 0≦x≦1, 0≦y≦1), are stacked in this order, and having the (100) surface appeared on the main surface thereof, and GaP transparent semiconductor layers 20, 90 stacked on the light emitting layer section 24 as being agreed with the crystal orientation thereof, so that the {100} surfaces appear on the side faces of the GaP transparent semiconductor layer. Accordingly, there can be provided a method of fabricating a light emitting device having the AlGaInP light emitting layer section and the GaP transparent semiconductor layers, less causative of failures such as edge chipping during the dicing.
    • 通过基于双异质结构对具有发光层部分24的发光器件晶片进行切割来获得发光器件芯片,其中第一导电型包覆层6,有源层5和第二导电型包层 (Al x Ga 1-x)y In 1-y P表示的化合物半导体中的每一个由具有允许与GaAs晶格匹配的组成的化合物半导体构成,其中,0≤x≤1,0< y <= 1)按顺序堆叠,并且在其主表面上出现(100)表面,并且与发光层部分24堆叠在一起的GaP透明半导体层20,90与晶体取向一致 ,使得{100}表面出现在GaP透明半导体层的侧面上。 因此,可以提供一种制造具有AlGaInP发光层部分和GaP透明半导体层的发光器件的方法,其不利于在切割期间的边缘切屑等故障。

    • A fuel cell device is disclosed that is capable of being made compact when being transported and in storage. The fuel cell device includes a fuel cell unit including a number of fuel cells arranged sequentially in a case. The case includes a holder frame for holding the fuel cells, a first hemi-case, and a second hemi-case. The width of the case is adjustable in the direction in which the fuel cells are arranged in a line. When the fuel cell device is being transported or in storage, the first hemi-case and the second hemi-case are pushed to approach each other, making the size of the case small. When the fuel cell device is used to generate electrical power, the first hemi-case and the second hemi-case are pulled apart from each other and, accordingly, the fuel cells are separated from each other by a springy plate.
    • 公开了一种燃料电池装置,其能够在运输和存储时被制造得紧凑。 燃料电池装置包括燃料电池单元,该燃料电池单元包括在壳体中顺次布置的多个燃料电池。 壳体包括用于保持燃料电池的保持架,第一半壳体和第二半壳体。 壳体的宽度可以在燃料电池排列成一行的方向上调节。 当燃料电池装置被运输或储存时,第一半箱和第二半壳被推动以彼此靠近,使得壳体的尺寸小。 当燃料电池装置用于产生电力时,第一半壳体和第二半壳体彼此分离,因此燃料电池通过弹性板彼此分离。
