摘要:
Provided are mixed ligand metal nanoparticle chemical sensors in which metal nanoparticles are encapsulated by at least two kinds of different molecule ligands having a relatively low conductivity and various composition ratios, and a chemical sensor array in which a film of the metal nanoparticle sensor is formed on the substrate. The metal nanoparticle sensor using the mixed ligand improves sensitivity and reaction speed with respect to an analyte, and selectivity with respect to various analytes, and a kind and a composition of a ligand of the mixed ligand constituting the metal nanoparticle sensor are adjusted to allow the high sensitivity nanoparticle sensor to be applied to the sensor array technology, thereby enabling a design of sensor properties as well as systematic access to a configuration of the sensor array the most efficient for the analytes.

A supporter for a clothes washing machine and a clothes drying apparatus for smoothly sliding a drawer in and out of a case regardless of temperature change by improving the structure of the drawer to be installed in the case. The supporter includes a case to support a clothes washing machine or a clothes drying apparatus and a drawer to be inserted into the case. The drawer includes a main body having an accommodating space, slide rails to be coupled with lateral sides of the main body, a connecting member to connect and support the slide rails, and a front panel to be coupled with a front side of the main body. The slide rails and the connecting member include first screw holes, and the main body further includes bosses at the lateral sides and the rear side of the main body. The bosses include second screw holes corresponding to the first screw holes. The connecting member and the main body include a position determining hole and a position determining protrusion at respective rear central portions. Fixed rails for sliding the slide rails are fixed to the inside of the lateral sides of the case.
摘要:
A washing machine with a detergent supply unit that allows a user to selectively put a powdered or liquid detergent into the same detergent input space and is capable of controlling flow of the detergent in the detergent input space to uniformly mix the detergent in wash water. The detergent supply unit includes a detergent container, at least one detergent input space formed in the detergent container, and a control member disposed in the detergent input space for controlling flow of a detergent in the detergent input space. Alternatively, the control member is disposed in the detergent input space for increasing or decreasing time for which the detergent stays in the detergent input space.
摘要:
A detergent supplying apparatus in which bleach or rinse is not supplied by mistake is disclosed. In order to directly discharge water remaining in a siphon cap after siphonage, concave steps are formed in the lower side of a siphon cap to form a passage between the siphon cap and the bottom of liquid detergent storing chamber. The detergent supplying apparatus includes a siphon cover having a plurality of siphon caps and a rib extended from the siphon caps by a predetermined length so that incorrect-coupling of the siphon caps is prevented.
摘要:
A washing machine having a detergent supply device for supplying detergent, filled in a detergent container, into a washing tub, in a mixed state with wash water. The detergent supply device includes a housing, a detergent container, and a restrictive element. The housing has a plurality of inlets connected with respective water supply pipes, and an outlet connected with a washing tub. The detergent container is detachably inserted in the housing and internally defines a liquid detergent receiving chamber. In the liquid detergent receiving chamber is provided a discharge member for discharging liquid, filled in the liquid detergent receiving chamber, into the water tub. The restrictive element is adapted to minimize fluctuation of the liquid filled in the detergent container when an external force acts on the detergent container.
