  • Patent number: 10031377
    Abstract: The circumferential part of an opening of an ejection part included in a nozzle head is formed in the shape of a convex curved plane. A liquid crystal droplet adhered to the portion with the shape of a convex curved plane of the ejection part smoothly flows down along the outer surface of the ejection part and is adhered to the opening end of the opening. The liquid crystal droplet adhered to the opening end of the opening is absorbed into the liquid crystal droplet to be ejected through the opening and is dispensed downward together with the liquid crystal droplet. This suppresses a large liquid crystal pool being formed on the outer surface of the ejection part. As a result, such problems that liquid crystal to be dispensed is absorbed into a liquid crystal pool while not being dispensed downward and that a large amount of liquid crystal is unnecessarily dispensed from a liquid crystal pool are both be suppressed. In other words, liquid crystal may appropriately be dispensed.

  • Patent number: 8205277
    Abstract: In the upper part and the lower part of a micro-nano bubble generation section 34 in a micro-nano bubble bathtub 1, two kinds of micro-nano bubbles different in a size distribution are generated by first and second micro-nano bubble generators (submerged pump-type micro-nano bubble generator 2 and spiral flow-type micro-nano bubble generator 10) of two kinds, so that bathtub water containing micro-nano bubbles in a wide size distribution can be produced in a large amount. Some of the water containing micro-nano bubbles generated in the lower part is thrown into the first micro-nano bubble generator (spiral flow-type micro-nano bubble generator 10) in the upper part, so that the spiral flow-type micro-nano bubble generator 10 can generate micro-nano bubbles in a smaller size. Therefore, in this bathtub, micro-nano bubbles abundant in size and large in amount can be produced economically.

  • Patent number: 7914677
    Abstract: Water (23) that contains micro-nano bubbles generated in a micro-nano bubble generation tank (6) is introduced and treated in a charcoal water tank (ii) which is filled with a charcoal (15) and in which an air diffusing pipe (12) is placed and thereafter introduced and treated in a membrane device (21). Thus, activities of microorganisms propagating in the charcoal (15) are increased by the micro-nano bubbles, markedly increasing ability of decomposing organic matters in the water. Therefore, a clogging phenomenon due to the organic matters can be prevented by reducing organic loads on the membrane device (21). Moreover, a very small amount of alcohols or salts are added as a micro-nano bubble generation aid to the micro-nano bubble generation tank (6), improving an incidence rate of the micro-nano bubbles. The alcohols and salts are easily decomposed by the charcoal water tank (ii) and easily removed by the membrane device (21).

  • Patent number: 7803272
    Abstract: A first treatment tank (1) to a fourth treatment tank are installed prior to ultrapure water production apparatus (5), dilute wastewater recovering apparatus (34), general service water recovering apparatus and wastewater treatment apparatus. The treatment tanks (1, 2, . . . ) each have a micro-nano bubble generation tank (6, 23, . . . ) and an anaerobic measuring tank (7, 24, . . . ). Accordingly, microbes within the respective anaerobic measuring tanks (7, 24, . . . ) are activated by micro-nano bubbles generated in each micro-nano bubble generation tank (6, 23, . . . ) to thereby enhance the treatment efficiency of low-concentration organic matter. Further, when the value measured by dissolved oxygen meter (13, 30, . . . ) or oxidation-reduction potentiometer (14, 31, . . . ) of each anaerobic measuring tank (7, 24, . . . ) exceeds an individually determined given range, the rotational speed of a circulating pump (9, 26, . . . ) is controlled to thereby decrease the generation of micro-nano bubbles.

  • Patent number: 7662288
    Abstract: In a water treatment system, micro-nano bubbles are used in a production device and a detoxification device as one example of the upstream treatment devices which perform specified treatment with use of water. The micro-nano bubbles are used again in the waste water treatment by a waste water pretreatment device and a waste water treatment device in the subsequent step. Since the micro-nano bubbles are reused, the efficiency of the micro-nano bubbles can be enhanced. Moreover, according to the waste water pretreatment device, treatment water is pretreated with the microorganisms activated by micro-nano bubbles and propagating in a polyvinylidene chloride filler material and then it is introduced into the waste water treatment device in the subsequent step. Thereby it is possible to reduce the waste water treatment load in the waste water treatment device in the subsequent step.

  • Patent number: 7641802
    Abstract: In a micronanobubble reaction vessel 3 of wastewater treatment equipment, wastewater containing organic matter is treated with micronanobubbles. Thereafter, the wastewater is introduced into an aeration tank 7. Part of organic matter in the wastewater is oxidized in the micronanobubble reaction vessel 3 by micronanobubble treatment prior to treatment with activity of microorganisms enhanced in the aeration tank 7. After organic matter load is thus reduced, the treatment water is introduced into the aeration tank 7, in which microorganisms exist in high concentration due to submerged membranes 17, so that the organic matter in wastewater can be effectively treated. This makes it possible to accomplish miniaturization of the aeration tank 7, reduction in scale of the whole equipment and therefore reduction in initial cost.

  • Patent number: 7632400
    Abstract: A water treatment equipment has a raw water tank as a mixing section, a micronanobubble generation tank, a floatation tank, and a treated water tank. Waste water as treatment water is introduced into the raw water tank and mixed with the water containing micronanobubbles produced by the micronanobubble generation tank. Thereafter, the waste water, as treatment water, is introduced into a lower mixing section of the floatation tank from the raw tank by a raw water tank pump. Also, treatment water containing fine bubbles is introduced into the lower mixing section from a pressure tank. Therefore, the micronanobubbles is mixed with the fine bubbles in the lower mixing section of the floatation tank, thereby almost all the suspended matter in the treatment water is surfaced. Thus, the water treatment equipment enhances separatability of suspended matter.

  • Patent number: 7628912
    Abstract: 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.

  • Patent number: 7625484
    Abstract: A water treatment apparatus has a turbidity meter, which is a detection part, for detecting a generation state of bubbles in a micro/nano bubble generation state confirmation tank, as a turbidity of treatment water. The water treatment apparatus also has a controller, which is a control part, for receiving an signal representing the turbidity of treatment water detected by the turbidity meter, to control openings of air flow control valves in an interlocked manner in response to the signal, so that the amount of air flowing through the control valves is automatically controlled. The openings of the air flow control valves are controlled in an interlocked manner by the controller in such a way that the signal representing turbidity shows that the treatment water within the confirmation tank is whitely turbid (i.e., the turbidity shows not less than a specified value).
