20120083189 | CHEMICAL MECHANICAL POLISHING APPARATUS HAVING PAD CONDITIONING DISK AND PRE-CONDITIONER UNIT - A pad conditioning disk, a pre-conditioning unit, and a CMP apparatus having the same are provided. The pad conditioning disk includes a base in which mountain-type tips and valley-type grooves are repeatedly connected to each other, and a cutting layer formed on the base layer. The cutting layer including conditioning particles deposited on surfaces of the tips and grooves. A surfaces roughness of conditioning particles deposited on the surfaces of the tips is less than a surface roughness of conditioning particles deposited on the surfaces of the grooves. | 04-05-2012 |
20120100169 | Vaccine for Cervical Cancer - The present invention relates to a pharmaceutical vaccine composition for a human cervical cancer, comprising: (a) (i) a L1 virus-like particle (VLP) of human papillomavirus (HPV) type 16, a L1 VLP of HPV type 18, or a combination thereof; and (ii) a deacylated non-toxic lipooligosaccharide (LOS); and (b) a pharmaceutically acceptable carrier; and a method for preparing a human papillomavirus (HPV) L1 virus-like particle (VLP). The pharmaceutical vaccine composition of the present invention is in both Th1-type immune response (cellular immunity) and Th2-type immune response (humoral immunity) against HPV more excellent than Cervrix™ and Gardasil™, exhibiting a superior efficacy as a vaccine for a human cervical cancer. | 04-26-2012 |
20130194832 | CONVERTER DRIVING CIRCUIT, DUAL-MODE LLC RESONANT CONVERTER SYSTEM, AND METHOD OF DRIVING DUAL-MODE LLC RESONANT CONVERTER - Disclosed herein are a converter driving circuit for adjusting a variable range of a driving control voltage according to an amplitude and frequency change of a feedback voltage, a dual-mode LLC resonant converter system, and a method of driving the dual-mode LLC resonant converter. | 08-01-2013 |
20140035684 | CONTROL CIRCUIT AND APPARATUS FOR DIGITALLY CONTROLLED OSCILLATOR - There are provided a control circuit for a digitally controlled oscillator and a control apparatus for a digitally controlled oscillator using the same. The control circuit for a digitally controlled oscillator includes: a peak detection circuit detecting amplitude of a signal output from the digitally controlled oscillator; and a transconductance control circuit comparing an output of the peak detection circuit with a predetermined reference signal to control a transconductance value of a negative transconductance circuit included in the digitally controlled oscillator. | 02-06-2014 |
20140186888 | METHOD FOR ENHANCING THE PRODUCTION YIELD OF HUMAN PAPILLOMAVIRUS L1 PROTEIN - This invention is a method for improving production yield of HPV L1 protein including the phase of culturing cell expressing HPV L1 protein in a medium containing high concentration of carbon source. According to the culture method using a medium containing highly concentrated carbon source of this invention, the production yield of HPV L1 protein can be not only remarkably increased but also the immunogenicity of the produced HPV L1 protein is significantly increased. | 07-03-2014 |
20140297300 | DISEASE MANAGEMENT SYSTEM AND METHOD USING A WIRED/WIRELESS COMMUNICATION NETWORK - A disease management system and method that use a wired and wireless communication network, in which motivation and consistent encouragement to change a behavior of a user or a patient may be given by close acquaintances or other people who have knowledge about a corresponding disease, instead of an expert. Thus, with regard to disease management that consistently needs normal and frequent communication, a role of an expert may be minimized to a necessary degree, and a more effective and efficient health care service, compared to a conventional health care service, may be provided. | 10-02-2014 |
20150263625 | USING A DIGITAL DELAY LOCKED LOOP SYNCHRONOUS DIRECT CURRENT TO REDUCE THE ELECTROMAGNETIC INTERFERENCE-WAVE CONTROL METHOD OF A DC BUCK CONVERTER AND THE SWITCHING SIGNAL - A synchronous direct current (DC)-DC buck converter and a method of controlling the waveforms of switching signals disclosed herein. The synchronous DC-DC buck converter generates a stepped-down output voltage using a first switch configured to apply an input voltage to an inductor and a second switch configured to switch in response to a second switching signal. The synchronous DC-DC buck converter includes a sawtooth generation unit, a driver oscillating signal generation unit, a switching signal generation unit, and a phase tracking unit. The sawtooth generation unit generates a sawtooth wave. The driver oscillating signal generation unit generates an error voltage between the output voltage and a reference voltage, and compares the sawtooth wave with the error voltage, so as to generate a driver oscillating signal. The switching signal generation unit generates each of the first and second switching signals. The phase tracking unit generates the frequency setting signal. | 09-17-2015 |
