Abstract: The present disclosure relates to an apparatus for producing silicon nanocrystals, which can minimize plasma diffusion by finely adjusting a plasma region created by an ICP coil. The apparatus includes a reactor having an ICP coil wound around an outer wall thereof and a tube inserted into the reactor, wherein a primary gas for forming silicon nanocrystals and a secondary gas for surface reaction of the silicon nanocrystals are separately supplied to the reactor through an inner side and an outer side of the tube, respectively.

Abstract: A heating cabinet is provided capable of keeping foods warm by use of solar energy. The heating cabinet includes a body member, which has an outer surface formed using transparent material and is configured to form an accommodation space therein, in which an inside of a part surrounding the accommodation space to be filled with heat retaining fluid heated by solar energy such that heat received from solar energy is stored in the heat retaining fluid to keep contents accommodated in the accommodation space warm; and a detachable member which is formed at one side of the body member to allow the body member to be detachable to the window. Foods contained in the heating cabinet are kept warm. When taking foods contained in the heating cabinet, a user takes foods by separating the heating cabinet from the window. Alternatively, a user separates the heating cabinet from the window and takes foods while carrying the separated heating cabinet.

Abstract: A PDP (plasma display panel) includes: a first substrate; a second substrate arranged opposite to the first substrate; first barrier ribs arranged between the first substrate and the second substrate and formed of a dielectric material; second barrier ribs arranged between the first barrier ribs and the second substrate and formed of a dielectric material, the second barrier ribs partitioning discharge cells together with the first barrier ribs; first discharge electrodes arranged within the first barrier ribs to surround the discharge cells; second discharge electrodes arranged within the second barrier ribs to surround the discharge cells; phosphor layers arranged within the discharge cells; and a discharge gas injected in the discharge cells, in which sides of the first and second barrier ribs form concave portions.

Abstract: A hybrid induction motor comprises a stator fixedly installed in a casing, an induction rotor rotatably inserted into a center of the stator and having a shaft at a center thereof, a first synchronous rotor installed between the stator and the induction rotor in a circumferential direction of the shaft so as to be freely rotatable, and a second synchronous rotor facing the first synchronous rotor in a longitudinal direction of the shaft and installed between the stator and the induction rotor so as to be freely rotatable.

Abstract: A method for assigning a channel in multi-FA CDMA mobile communication system according to the received power prevents communication quality of a FA from being inferior to that of the others by managing the interference level of the FA. The method comprises the steps of: comparing a first threshold value with received power when the base station receives a new call request; assigning a traffic channel in a first FA of the request, if the received power is less than the first threshold value, and searching a second FA of which received power is least, if not; comparing a second threshold value with the received power of the second FA; and assigning a traffic channel in the second FA if the received power is less than the second threshold value, and rejecting the request, if not.

Abstract: In manufacturing embroidered patch attached to the apparel like cap, bag, clothes and others, the present invention makes it possible to reduce the process and to improve the productivity amazingly. The embroidered patch and the manufacturing method thereof according to the present invention has the feature that it comprises the embroidery portion embroidering non-woven fabric having a certain thickness and the edge portion sewn along the circumference line of said embroidery portion. 1˜2 mm thickness of soft material may be added to said non-woven fabric for thicker embroidered patch. For said soft material, EVA(Ethylene Vinyl Acetate) is usually used and the embroidered patch is completed by detaching the non-woven fabric and the soft material which is not embroidered.

Abstract: A device for controlling the operation of power excavators includes a control lever which is handled simply by one hand, which is different from the prior art systems having multiple control levers necessarily handled by both hands. The control lever consists of a plurality of links which are jointed together in such a way that the intuitive handling directions of the links are identified with the actual moving directions of the actuators. The control lever thus adds significant convenience for the operator when operating the actuators of the excavator. An excavator with the above control device can be easily and effectively operated by an unskilled operator even for delicate work such as a land finishing work or loading work, both of which tasks are generally known in the art to require a highly-skilled operator.
