Abstract: The present invention relates to a catalyst for hydrogenation and a method for preparing the same, and more specifically, provides a catalyst having improved activity by including copper and copper oxide as a promoter when a hydrogenation catalyst including nickel is prepared by using a deposition-precipitation (DP) method. Accordingly, a catalyst having high activity may be provided in a hydrogenation process of a hydrocarbon resin.

Abstract: A Peripheral Component Interconnect Express (PCIe) device includes a plurality of lanes comprising a plurality of ports, a link controller setting a link including the plurality of lanes, wherein the link is set to have a link width that includes the remaining of lanes, except for a fail lane from among the plurality of lanes, and an EQ controller performing an equalization operation for determining a transmitter or receiver setting of each of the remaining lanes, wherein the EQ controller determining a final EQ coefficient using a log information and an error information.

Abstract: An SSD device comprises a first port linking up with a first host using a first link, a second port linking up with the first host or a second host using a second link, and a port mode controller controlling the first port and the second port to change an operating mode from a dual port mode, in which the first port and the second port operate independently of each other, to a single port mode, in which only the first port operates. The port mode controller controls the second port to reset the second link in a state where the first link is linked up.

Abstract: A Peripheral Component Interconnect Express (PCIe) interface device may include a PCIe layer, a link training module, a PCIe register, and a PCIe controller. The PCIe layer may perform communication between a host and a Direct Memory Access (DMA) device. The link training module may perform a link training for the host. The PCIe register may store data information on the PCIe layer. The PCIe controller may switch an operating clock from a PCIe clock, generated based on a reference clock, to an internal clock, process data of the PCIe layer on the basis of the internal clock, and control the link training module to recover a link for the host, when a reset signal received from the host is asserted or the reference clock is off.

Abstract: A linear guide system which is used for highly precise control of a linear position applicable in display devices, semiconductors, robots, machine tools, and the entire measurement and precision instruments industry, and more specifically, an adjustable preload type linear guide system, wherein a base member and a slide member are slidably connected with each other for linear motion, and a linear motion actuator, such as a ball screw, a hydraulic cylinder, and a linear motor, is disposed between the base member and the slide member, thereby enabling the slide member to move linearly relative to the base member.
