Abstract: The present invention relates to method and apparatus for providing an arbitrary sound chosen by a called subscriber instead of ringback tone to a calling subscriber. In this present invention, if a call is received, a terminating exchanger requests a trunk connection to a sound db server based on the first information on whether or not to replace a ringback tone and the second information on a route to the sound db server that are received from a home location register (HLR), and provides a called subscriber identification for the sound server. Then, the sound db server searches its db for a sound specified by the called, and provides the found sound for the caller instead of a conventional ringback tone via the terminating exchanger connected through a trunk. Through this sequential procedure of network elements, a caller can hear a sound specified by a called instead of a dry ringback tone.

Abstract: Provided is a voltage-controlled oscillator (VCO) using a current feedback network for use in a wireless communication terminal. The voltage-controlled oscillator has high input impedance and low output impedance, so that a degree of isolation from the external load is excellent, thereby preventing degradation of the Q-factor by the load in overall oscillation circuit. In the voltage-controlled oscillator of the present invention, an LC resonator is provided to generate positive feedback, and negative resistance may be obtained at a wider frequency range by tuning a varactor of the LC resonator. And a boosting inductor is inserted into the positive feedback loop to have a greater negative resistance, therefore it is possible to prevent a problem in which the oscillation does not occur due to the parasitic resistance components generated during circuit fabrication.

Abstract: An integrated type optical coupling device capable of easily accurately performing an optical arrangement between a narrow-pitch multi-channel optical waveguide and an optical fiber array and a master used in fabricating the same are provided. By forming a fixing projection between the optical fibers, the dynamic stability of the optical fiber array is increased and the optical arrangement between the optical waveguide and the optical fiber is easily accurately performed by hand. Accordingly, the cost required for the alignment is reduced and the alignment error due to the rolling of the optical fiber is not generated. In addition, the multi-step metal master is fabricated by using a photoresist film for X-ray exposure, and the narrow-pitch multi-channel optical coupling device is fabricated in a hot embossing method using the same, thereby the high-integrated device can be fabricated at a low price.

Abstract: A wavelength tunable filter capable of being driven such that reflecting mirrors move more distant as well as closer by using the principle that a direction of the electromagnetic forces changes depending on the direction of the current flowing perpendicular to the external magnetic field. According to the wavelength tunable filter of the present invention, when it is necessary to have the wavelength tuning range and mechanical structure similar to the conventional wavelength tunable filter driven in only one direction, it is possible to lower the maximum force needed to drive the filter to a half, and reduce a probability that a pull-in phenomenon occurs. On the other hand, it is possible to reduce a wavelength change time of the element by increasing a resonant frequency when the same wavelength tuning ranges are implemented by using the same maximum driving forces.

Abstract: A row decoder circuit of a NAND flash memory and method of supplying an operating voltage using the same. To prevent an operating voltage (e.g., a program voltage, a pass voltage, or a read voltage) from being abnormally transferred to a gate of a memory cell because a pumping voltage is applied to a gate of a high-voltage pass transistor of the row decoder circuit in a level lower than a target voltage, the pumping voltage is first applied to the gate of the high-voltage pass transistor (i.e., precharging the gate of the high-voltage pass transistor) and next the operating voltage is applied to a drain of the high voltage pass transistor. Thus, the pumping voltage becomes higher than the target voltage due to a self-boosting effect through the structure of transistor, enabling the operating voltage to be normally transferred to the gate of the memory cell.

A UDA table creation section makes use-relation between an object and a use-case transmitted from the input section into a UDA (Use-case Data Access) table. A clustering engine creates at least one identified component by normalizing affinity values between use-relation factors in a UDA table prepared in the UDA table creation section and by performing a clustering only for a value greater than or equal to a threshold among the normalized affinity values.

Having no polyurethane, the headband is woven to single ply or two-ply without an additional stitched portion, and exhibits good elasticity as a whole through the napped, felt-like structure of the textile. The circumferential stretch direction of the headband also provides excellent sweat absorption capability. With this construction a wide range of automatic size adjustment is obtained without imposing undue elastic pressure on the wearer such that the cap and headband are comfortable for extended periods of wear.
Abstract: The present invention relates to a method for fabricating a semiconductor device. In more detail of the aforementioned method, a first mask layer covering a cell region is formed on an insulation layer in the cell region. Meanwhile, a second mask layer is formed in a peripheral circuit region with a predetermined distance from the first mask layer. The insulation layer is then etched with use of the first and the second mask layers as an etch mask to form a spacer at both sidewalls of each gate line pattern in the peripheral region and simultaneously form a guard beneath the second mask layer. The first and the second mask layers are removed thereafter. Next, a third mask layer opening the cell region but covering the whole regions including a guard region in the peripheral circuit region is formed. A wet etching process is performed to the insulation layer remaining in the cell region by using the third mask layer as an etch mask.
