    • A shell-and-tube type heat exchanger of the smallest possible length necessary for heat exchange is disclosed which is capable of obtaining uniform distribution of flow of a shell side fluid and substantially eliminating the structural restriction imposed on the shell side. This shell-and-tube type heat exchanger is provided with one annular conduit furnished with not less than two partitions concurrently serving as an expansion joint for introducing and discharging a shell side fluid and allowing the flow path for said shell side fluid to be separated into an introducing part and a discharging part and which comprises a place having no array of heat-transfer tubes in the flow path for said shell side fluid. It prevents the equipment from necessitating an unnecessary enlargement due to the structural restriction on the shell side and enables the shell side fluid to produce a uniform flow.
    • 公开了一种能够获得壳侧流体的均匀流动分布并且基本上消除了对壳体侧面的结构限制的壳体管式热交换器,其具有热交换所需的尽可能小的长度。 这种管壳型热交换器设置有一个环形导管,其具有不少于两个隔板,同时用作用于引入和排出壳侧流体的膨胀接头,并且允许将所述壳侧流体的流动路径分离成 引入部分和排出部分,并且包括在用于所述壳侧流体的流动路径中不具有热传递管阵列的位置。 它防止了由于壳体侧面的结构限制而使设备不必要地增大,并且使得壳侧流体能够产生均匀的流动。

    • An optical element is disclosed which has a reflection suppressing function and a color balance correcting function in a minute periodic structure. The optical element has a base member and a minute periodic structure which is provided on a surface of the base member and has a period smaller than a wavelength of incident light on the optical element. The minute periodic structure has a characteristic that the reflectance of light a first wavelength on a short wavelength side in a wavelength range of the incident light is lower than the reflectance of light at a second wavelength on a long wavelength side in the wavelength range of the incident light.
    • 公开了一种在微小周期性结构中具有反射抑制功能和色平衡校正功能的光学元件。 光学元件具有底座部件和微小的周期性结构,该基体部件设置在基体部件的表面上,其周期比入射光的波长小于光学元件。 微小周期结构具有以下特征:入射光的波长范围内的短波长侧的第一波长的光的反射率低于在波长范围内的长波长侧的第二波长的光的反射率 入射光。
