Abstract: A fluid power generation device is configured to provide electric power generation using fluid action, and comprises multiple power generation mechanisms. Each power generation mechanism comprises: a casing that allows a fluid to pass through its internal space; and a power generation unit arranged within the casing, and configured to perform electric power generation using the fluid action. The casing is configured to generate vortexes in the vicinity of its fluid outlet. The multiple casings are arranged with spaces as intervals between them. Each casing generates vortexes in the vicinity of its fluid outlet. Furthermore, such an arrangement provides an interaction effect between the vortexes generated in the vicinity of the fluid outlets of the multipole casings arranged with the spaces as intervals between them. This provides a synergistic effect for accelerating the inner flow based on the interaction between the power generation mechanisms.

Abstract: A substrate processing method according to an embodiment includes an etching process, a temperature-difference forming process, and a rinsing process. The etching process supplies an etchant onto a first surface of a substrate on which a pattern is formed to etch the pattern. The temperature-difference forming process makes, in parallel with the etching process, a temperature in a lower portion of the pattern lower than a temperature in an upper portion of the pattern. The rinsing process supplies rinse liquid onto the first surface after the etching process to replace the etchant remaining on the pattern with the rinse liquid.

Abstract: A conductive film stuck to a transparent conductive film of a liquid crystal panel is protruded along a display surface and the protruded part is formed as non-adhesive so that the protruded part is not stuck to the members other than the liquid crystal panel. The protruded part contacts with a conductor on the front frame side so as to electrically connect the transparent conductive film of the liquid crystal panel and the front frame. When the liquid crystal panel moves, the conductive film can move in a direction in parallel to the display surface by following the liquid crystal panel, which prevents deterioration of the conductive film. Therefore, no excessive force works on the stuck part between the transparent conductive film and the conductive film. It solves the exfoliation issue of the conductive film, and the transparent conductive film can be electrically connected to the front frame stably.
