20090061550 | LED PACKAGE AND FABRICATING METHOD THEREOF - The invention provides an LED package capable of effectively releasing heat emitted from an LED chip out of the package and a fabrication method thereof. For this purpose, at least one groove is formed on an underside surface of the substrate to package the LED chip and the groove is filled with carbon nanotube material. In the LED package, a substrate having at least one groove on the underside surface is prepared. A plurality of electrodes are formed on a top surface of the substrate. Also, at least the one LED chip is mounted over the substrate to have both terminals electrically connected to the upper electrodes. In addition, carbon nanotube filler is filled in the groove of the substrate. | 03-05-2009 |
20090107616 | MANUFACTURING METHOD OF MULTI-LAYER CERAMIC SUBSTRATE - Provided is a manufacturing method of a multi-layer ceramic substrate. The manufacturing method includes preparing an unsintered ceramic laminated body with a cavity, mounting a chip device within the cavity, filling the cavity, in which the chip device is mounted, with a ceramic slurry, attaching a constrained layer on top and/or bottom of the ceramic laminated body, and firing the ceramic laminated body. Accordingly, since the deformation of the cavity is prevented during the firing of the ceramic laminated body, the dimension precision and reliability of the multi-layer ceramic substrate can be improved. | 04-30-2009 |
20100101701 | METHOD OF MANUFACTURING NON-SHRINKING MULTILAYER CERAMIC SUBSTRATE - Disclosed is a method of manufacturing a nonshrinking multilayer ceramic substrate. The method includes forming at least one conductive via and an electrode pattern in at least one of a plurality of ceramic green sheets, laminating the ceramic green sheets to form a ceramic laminate, selectively forming a shrinkage inhibiting thin film of sinter-resistant powder on a region including the conductive via and a periphery thereof in at least one of two surfaces of the ceramic laminate using aerosol deposition, disposing a shrinkage inhibiting green sheet for suppressing the shrinkage of the ceramic laminate on at least one of the two surfaces of the ceramic laminate including the shrinkage inhibiting thin film to form a non-sintered multilayer ceramic substrate, and sintering the non-sintered multilayer ceramic substrate. | 04-29-2010 |

20080317274 | Apparatus for Necklace Type Radio Headset - Disclosed is a necklace type radio headset capable of overcoming problems of conventional headsets, in which cables connected between earphones of a headset easily get tangled with each other or with other objects in a storing place of the headset while the headset is not used. The headset according to the present invention includes casings connected via a cable and enclosing one or more Bluetooth modules and respective speakers therein, and the casings are detachably coupled to each other by a coupling means, so that a user can wear the headset around his or her neck like a necklace because the cable always maintains a ring shape. As the coupling means, one of the casings has a depression for receiving a speaker housing to be inserted into a user's ear, and the speaker housing is input in the depression while it is not used. Further, since either or both of the casings have respective permanent magnets, the casings are coupled by attractive magnetic force exerted between the permanent magnets. According to the present invention, cables of a headset do not easily get tangled with each other or do not easily get tangled with other objects. Further, since a user can carry the headset by putting the headset around his or her neck, the headset cannot easily be lost. | 12-25-2008 |

20150200637 | BIOSIGNAL AMPLIFYING CIRCUIT - A biosignal apparatus is described including an amplifier and a sampler. The amplifier is configured to alternate between an operating state and a low power state based on a periodically changing control signal. The sampler is configured to sample a signal output from the amplifier in response to the amplifier being in the operating state and maintain the sampled signal in response to the amplifier being in the low power state. | 07-16-2015 |

20100120042 | METHOD OF SCREENING MATERIAL FOR IMPROVING SKIN FUNCTIONS - A method of screening a material for improving skin functions includes: (a) treating a skin cell with a candidate material; (b) detecting a change in a relative expression level of membrane-associated protein 17 (MAP17) gene; and (c) selecting a candidate material inducing the change in the expression level of the gene as a material for improving skin functions. That is to say, a material for improving skin functions is screened using MAP17 gene as a marker, on the basis of the change in the expression level of the MAP17 gene. A material for improving skin functions, which is useful in improving skin barrier function, promoting skin moisturization, preventing skin aging, or ameliorating skin troubles, may be effectively screened. | 05-13-2010 |
20110212455 | METHOD OF SCREENING MATERIAL FOR IMPROVING SKIN FUNCTIONS - A method of screening a material for improving skin functions includes: (a) treating a skin cell with a candidate material; (b) detecting a change in a relative expression level of membrane-associated protein 17 (MAP17) gene; and (c) selecting a candidate material inducing the change in the expression level of the gene as a material for improving skin functions. | 09-01-2011 |
