A liquid supply controller includes a liquid circulation controller that includes supply and recovery units of a liquid droplet discharge unit, and that circulates liquid according to a differential pressure between the supply unit and the recovery unit, a back pressure setting unit that sets a back pressure that is a discharge pressure based on supply and recovery pressures set by the liquid circulation controller, a circulation amount obtaining unit that obtains a flow rate of the liquid circulated; a judging unit that judges whether or not the obtained flow rate is a proper value, and a differential pressure adjusting unit that adjusts the differential pressure while maintaining the back pressure within an allowable range when it is judged that the flow rate is not the proper value.
摘要:
Drainage water containing an organofluorine compound is introduced into a raw tank (1) and then filtered through a filtration device (4). Next, a microorganism, a micro-nanobubbling auxiliary agent and a nutrient are added thereto in a first transit tank (5) while micro-nanobubbles are generated thereinto by a micro-nanobubbling machine (7), thereby giving treated water. This treated water is then fed into an active carbon column (14) and then the above-described organofluorine compound contained in the treated water is decomposed by the microorganism as described above.

A simulation system having multiple peripherals that communicate with each other. The system includes a weighted graph with weights set as communication times. The peripherals are represented as nodes and connection paths are represented as edges. Among the communication times in the loop, the minimum time is set as first synchronization timing. Timing with an acceptable delay added is set as second synchronization timing. Timing set by a user to be longer than the first and second timings is set as third synchronization timing. The third synchronization timing is used in a portion where the timing is usable, thus synchronizing the peripherals at the longest possible synchronization timing.
摘要:
A droplet ejection apparatus includes a common flow path; droplet ejection units each respectively including a first distribution port; first flow paths that respectively connect each first distribution port to the common flow path; first open/close mechanisms provided respectively at the first flow paths; a first pressurizing unit that applies a positive pressure to the common flow path; a second open/close mechanisms provided at the common flow path at the first pressurizing unit side of connection portions that connect the common flow path and the respective first flow paths; and a controller. When the second open/close mechanism is closed, the controller opens only one or more first open/close mechanisms corresponding to one or more target droplet ejection units, applies positive pressure to a section of the common flow path at the first pressurizing unit side of the second open/close mechanism, and then opens the second open/close mechanism.
摘要:
A droplet ejection apparatus includes droplet ejection units each including a supply port and an ejection port, a common supply flow path, a common discharge flow path, supply flow paths that connect the supply port to the common supply flow path, openable mechanisms provided at the supply flow paths, discharge flow paths that connect the ejection port to the common discharge flow path, one-way valves provided at the discharge flow paths, a pressure applying unit, and a controller. When performing a maintenance operation of a selected droplet ejection unit, the controller applies a pressure with the pressure applying unit so that the pressure in the plural discharge flow paths at the common discharge flow path side with respect to the respective one-way valves is higher than the other side, and opens only the openable mechanism corresponding to the selected droplet ejection unit.
摘要:
The application device for liquid containing micro-nano bubbles generates micro-nano bubbles in a wide size distribution with use of a submerged pump-type micro-nano bubble generator and a spiral flow-type micro-nano bubble generator. A micro-nano bubble generating aid metering pump is controlled by a bubble level meter and a level controller, so that the supply amount of a micro-nano bubble generating aid is controlled in response to the level of bubbles from a fluid level. The supply amount of a micro-nano bubble generating aid is also controlled by a turbidimeter and a controller in response to the turbidity of the liquid in a micro-nano bubble generation tank, while the amount of air supplied to the submerged pump-type micro-nano bubble generator is controlled in response to the turbidity of the liquid. Therefore, the device can produce a large amount of various micro-nano bubbles in a wide size distribution more economically.
