Patent number: 11942955Abstract: A delay locked loop circuit includes a delay line, a phase detector, a selection controller, and a charge pump. The delay line delays, based on a delay control voltage, a reference clock signal to generate an internal clock signal and a feedback clock signal. The phase detector compares phases of the internal clock signal and the feedback clock signal to generate a first detection signal and a second detection signal. The selection controller provides the reference clock signal as an up-signal and a down-signal. The charge pump generates the delay control voltage based on the up-signal and the down-signal.Type: GrantFiled: May 31, 2023Date of Patent: March 26, 2024Assignee: SK hynix Inc.Inventors: Yun Tack Han, Kyeong Min Kim

Patent number: 9371269Abstract: The present invention provides a method for preparing dialkyl carbonate from urea or alkyl carbamate and alkyl alcohol using an ionic liquid comprising a cation, which produces a hydrogen ion, and a hydrophobic anion containing fluorine with high temperature stability in the presence of catalyst containing a metal oxide or hydrotalcite. Since the present invention can prepare dialkyl carbonate at a pressure lower than those of existing methods, it does not require an expensive pressure control device and peripheral devices for maintaining high pressure including the installation cost. It is also the method for preparing a dialkyl carbonate with high yield, thus improving economical efficiency. Moreover, the method of the present invention hardly produces any waste during the process and is thus an eco-friendly method.Type: GrantFiled: December 9, 2013Date of Patent: June 21, 2016Assignee: RESEARCH INSTITUTE OF INDUSTRIAL SCIENCE & TECHNOLOGYInventors: Jae Cheon Koh, Chul Ung Kim, Yun Min Kim
