Abstract: A multilayer ceramic capacitor includes a ceramic body having a dielectric layer, a plurality of internal electrodes disposed in the ceramic body, and a first side margin portion and a second side margin portion arranged on end portions of the internal electrodes exposed through respective opposing surfaces of the ceramic body. The ceramic body includes an active portion having the plurality of internal electrodes arranged to overlap each other with the dielectric layer interposed therebetween to form capacitance, and cover portions disposed above an uppermost and below a lowermost internal electrode of the active portion. The first and second side margin portions include tin (Sn), and a content of Sn included in the first and second side margin portions is greater than a content of Sn included in the dielectric layer of the active portion.

Abstract: A substrate analysis apparatus is provided. The substrate analysis includes: an interlayer conveying module configured to transport a first FOUP; an exchange module which is connected to the interlayer conveying module, and configured to transfer a wafer from the first FOUP to a second FOUP; a pre-processing module configured to form a test wafer piece using the wafer inside the second FOUP; an analysis module configured to analyze the test wafer piece; and a transfer rail configured to transport the second FOUP containing the wafer and a tray containing the test wafer piece. The wafer includes a first identifier indicating information corresponding to the wafer, the test wafer piece includes a second identifier indicating information generated by the pre-processing module which corresponds to the test wafer piece, and the analysis module is configured to analyze the first identifier and the second identifier in connection with each other.

Abstract: The present invention relates to an irradiation device for material test using a gamma ray radiated from a spent nuclear fuel assembly and provides the irradiation device for material test using a gamma ray radiated from a spent nuclear fuel assembly wherein an irradiation device for material test to achieve a radiation effect evaluation is manufactured to be movable upward, downward and horizontally in order to study the hardening phenomenon of the frail materials to the radiation among the atomic power facilities using a gamma ray radiated from a spent nuclear fuel assembly, thereby it is possible to adjust a position of the spent nuclear fuel used for material test using a gamma ray radiated from a spent nuclear fuel and a test material, identify a distance between the spent nuclear fuel and the test material easily with a scale and evaluate the radiation effects on the materials used at facilities handling a spent nuclear fuel under the same situation as they are really exposed.

Abstract: A joint tong apparatus for a radiation shielding facility. A spherical ball has a through-hole. An inner spherical socket and an outer spherical socket are installed in a hole formed in a partition between a radiation-shielded room and a control room so as to enclose the spherical ball on inner and outer sides. A bar is inserted and coupled into and to the through-hole of the spherical ball. An inner joint assembly has a first housing coupled to a shielded room-side end of the bar and a first pivot member pivotably mounted on a free end of the first housing. An outer joint assembly having a second housing coupled to a control room-side end of the bar and a second pivot member pivotably mounted on a free end of the second housing. The apparatus further includes a tong assembly, a handle assembly, a tong manipulation cable, and a pair of pivot manipulation cables.

Abstract: A rear door system for transferring hot cell equipment into or out of a hot cell is disclosed. The rear door system of the present invention includes a rear door, which is provided to a rear wall of the hot cell so as to be movable to open or close the rear wall of the hot cell, and a vertical moving table, which is provided at a predetermined position on the lower portion of the front surface of the rear door so as to be movable upwards or downwards.

Abstract: The present invention relates to a frequency detection method for an optical disc bit data reproduction apparatus. The frequency detection method uses the optical disc bit data reproduction apparatus including an Analog to Digital Converter (ADC), an interpolator, an asymmetry compensator, a digital bit and successive bit length detector, a frequency detector, a phase detector and a Digital Controlled Oscillator (DCO). In the frequency detection method includes the primary frequency detection step and the secondary frequency detection step. In the primary frequency detection step, status of input RF digital bit data frequency versus sampling frequency is determined and the sampling frequency is corrected so as to allow the sampling frequency to be rapidly adjusted to the frequency of the RF digital bit data, thus primarily detecting frequency.
