Abstract: <P>PROBLEM TO BE SOLVED: To provide a slope-toe structure of a river which prevents scouring by constructing the revetment of a river, ensures the strength of the revetment, and avoids an adverse effect on an ecosystem of running-up fish.  <P>SOLUTION: Continuous hollow structures (20) are arranged along the lower edge of a bank slope of the river, and openings (27) having sizes that allow fish to enter the same are formed at appropriate locations (e.g. in a side surface on a water-flowing side) of the continuous structures. Each continuous structure is almost trapezoidal in cross section, for instance, and it is preferred that the structure has an inclined wall surface expanding from an upper bed toward a bottom end on a river slope side. On the other hand, a wall surface on a non-slope side, i.e. on the water flowing side, can be an almost vertical wall surface from the upper bed to the bottom end.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

IPC: B05C5/00
Filed: 2003-02-12
Abstract: <P>PROBLEM TO BE SOLVED: To prevent a nozzle from being clogged by suppressing the deposition of solid components in a discharge opening.  <P>SOLUTION: An aluminum web 11 is converted into a mat by using an electrostatic applicator 10. A discharge head 16 of the applicator is supported by an air actuator 36, and the position and orientation of the head 16 can be changed. The discharge opening of the head 16 is made to face the web 11 when the web 11 is converted into the mat. When the conversion into the mat is stopped, the orientation of the head 16 is changed to be downward while the application of voltage and the discharge of liquid are continued. When the head 16 is turned downward, the liquid in the discharge opening and its vicinity is dropped to be received by a liquid receiver 18. In this way, the deposition of the solid components of the liquid in the discharge opening is suppressed to prevent the nozzle from being clogged. Therefore, even when the conversion into the mat is reopened, the conversion into the mat can be done well.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
