Disclosed is a water softening system includes a first and a second filter unit that selectively performs any one of a removable mode discharging soft water including less ionic material than a source water, and a recycling mode of discharging reclaimed water including more ionic material than the source water, a first and a second supply passage that supplies the source water to the first and the second filter unit, a first and a second discharge passage that discharges the soft water or the reclaimed water from the first and the second filter unit, a first recovery passage part that guides at least a portion of the reclaimed water in the first discharge passage to the second supply passage, and a second recovery passage part that guides at least a portion of the reclaimed water in the second discharge passage to the first supply passage.

Water softening system

A scale-free boiler of the present disclosure includes a boiler case, a main flow path disposed inside the boiler case and in communication with a heating flow path disposed outside the boiler case to provide heating, a heat source for heating water flowing along the main flow path, and a filter for removing, based on an electrical force, an ionic material contained in the water flowing along the main flow path or water to be supplied to the main flow path to prevent occurrence of scale.

Ion removal unit for water heater, and scale-free boiler, scale-free water heater, and portable ion remover including the same

An apparatus for controlling a water softener according to an exemplary embodiment of the present invention includes: a concentration detector detecting a concentration of total dissolved solids in water introduced into a channel; a voltage controller controlling a voltage applied to an electrode so that the detected concentration of the total dissolved solids reaches a target concentration; a flow rate detector detecting a flow rate of the water introduced into the channel; and a water softening time controller controlling, based on the detected flow rate, a water softening time for the water so that the detected concentration of the total dissolved solids reaches the target concentration.

Apparatus and method for controlling water softener

A water-softening system includes a filter device including filter units that are provided in at least some of a plurality of supply channels arranged in parallel to supply raw water to a consumption site and that remove at least part of ionic matter contained in supplied raw water by electro-deionization and discharge soft water containing less ionic matter than the raw water, a plurality of supply valves provided in the plurality of supply channels to open or close the supply channels, and a processor connected to the filter device and the plurality of supply valves. The processor determines whether water is supplied to the consumption site and controls at least one of the plurality of supply valves to remain open to maintain a state in which water is allowed to be supplied to the consumption site, when it is determined that no water is supplied to the consumption site.

Water-softening system

A CDI-type water treatment device according to the present invention comprises: a filter unit for purifying raw water in a CDI type through an electrode part formed by alternately stacking electrodes and separators; and a sterilization unit provided on the front of the filter unit to supply the electrode part with a sterilization substance, which has been generated from the raw water in order to sterilize the electrode part. The sterilization unit, in this case, preferably operates after a predetermined time has passed since the electrode part has both stopped purifying raw water and stopped regenerating the electrodes.

CDI-type water treatment method

A CDI type water treatment apparatus according to the present invention includes: a CDI filter unit which discharges purified water in a purification mode for purifying raw water, discharges recycle water in a recycle mode for recycling electrodes, and includes a water inlet port through which the raw water is introduced and a water outlet port through which the purified water or the recycle water is discharged; a supply unit for supplying the raw water to the CDI filter unit; a dispensing unit for dispensing the purified water to a user; a discharge unit for discharging the recycle water to the outside; a valve unit including a plurality of valves; and a control unit for controlling opening or closing the valves of the valve unit.

CDI type water treatment apparatus

The present invention relates to a pharmaceutical composition for preventing or treating diseases related to abnormal proliferation of cells, comprising a cytoplasmic heat shock protein (Hsp)60 kDa inhibitor as an active ingredient, and to a screening method and a kit using the composition. According to the present invention, substances which inhibit expression of cytoplasmic Hsp 60 genes or inhibit activity of cytoplasmic Hsp 60 or inhibit binding between cytoplasmic Hsp 60 and IKK protein prevent interaction between cytoplasmic Hsp 60 and IKK complexes to make NF-&#x3ba;B path inactive, and thus induce apoptosis. Therefore, the substances can be valuably used in preventing or treating diseases related to abnormal proliferation of cells, such as cancer, inflammatory diseases or hyperproliferative vascular diseases.

Pharmaceutical composition for inhibiting abnormal proliferation of cells

The present invention provides pyrazole derivative compounds and pharmaceutically acceptable salts thereof. The compounds of the present invention have an excellent effect of preventing and treating osteoporosis.

Pyrazole derivatives, preparation method thereof, and composition for prevention and treatment of osteoporosis containing same

Digest playback apparatus and method for a VCR. The digest playback apparatus includes a system controller for outputting a plurality of control signals to control the entire operation of a video cassette recorder system, the plurality of control signals including speed-change multispeed and direction data and audio multispeed change mode ON/OFF data. An analog/digital conversion circuit converts an analog audio signal read by an audio head and then restored to its original state into digital audio data regardless of a speed-change mode. A memory stores the digital audio data from the analog/digital conversion circuit. A digital/analog conversion circuit converts the digital audio data stored in the memory into an analog audio signal, and a control circuit controls the analog/digital conversion circuit, the memory and the digital/analog conversion circuit to output the analog audio signal from the digital/analog conversion circuit as a 1 multispeed which allows the user to accurately listen to the output analog audio signal.

A method for deciding recording density of an optical disc easily decides and searches the kind and data recording status of a disc when reproducing a general CD and a high density CD. The method is performed by a recording step of recording classification of the general disc and the high density disc, and identification and recording density status of respective layers of the high density CD onto both a zero area of a lead-in region and a zero area of a Q channel of a subcode, and a reproducing step in which the zero area of the lead-in region is read out to decide the recording density status and positional information with respect to respective musics, and the linear velocity of the spindle motor, tracking servo and focusing servo are controlled with respect to the decided respective musics. Thus, it is easy to search the music while accurately controlling the spindle motor, focusing servo and tracking servo according to the recording density.
