Latest Patent Applications

1. **FLOW CHANNEL SWITCHING DEVICE** - This application describes a five-port switch valve that includes a cylinder with five chambers defined by four partitions and two actuators. The valve body of one actuator alternately opens and closes a hole formed in the partition and another hole in a different partition. Similarly, the valve body of the other actuator alternately opens and closes two additional holes. This structure allows brine fed into the central chamber to be alternately directed into two pressure converters through designated ports.

2. **POWER RECOVERY APPARATUS** - In this application, a power recovery apparatus is designed for use in a desalination system that employs a reverse osmosis membrane to extract fresh water from seawater. The apparatus includes a pressure conversion section and a seawater supply section that collects energy from the concentrated water. The pressure conversion section features a movable part that divides the interior into first and second spaces. This movable part is activated by concentrated water entering the first space, which in turn pushes seawater from the second space to output it effectively. The seawater supply section merges the seawater from the pressure conversion section with that supplied to the reverse osmosis membrane.

Conclusion

Fumihide Nagashima's innovative approaches in flow channel technology demonstrate his potential to contribute significantly to advancements in fluid management systems. His latest patent applications reflect a commitment to developing efficient solutions in the field.
