Abstract: The present disclosure relates to a method for manufacturing core-shell particles using carbon monoxide, and more particularly, to a method for manufacturing core-shell particles, the method of which a simple and fast one-pot reaction enables particle manufacturing to reduce process costs, facilitate scale-up, change various types of core and shell metals, and form a multi-layered shell by including the steps of adsorbing carbon monoxide on a transition metal for a core, and reacting carbon monoxide adsorbed on the surface of the transition metal for the core, a metal precursor for a shell, and a solvent to form particles with a core-shell structure having a reduced metal shell layer formed on a transition metal core.

Abstract: Provided is a blood pressure measuring apparatus including: a pressurizing unit applying pressure to a blood vessel according to a first condition or a second condition; a pressure sensor sensing a sphygmus wave and a pressure of the blood vessel from the blood vessel under the first condition or the second condition; a standard blood pressure calculating unit for calculating a systolic standard blood pressure and a diastolic standard blood pressure; a continuous blood pressure calculating unit for calculating continuous blood pressure; and a repressurizing determining unit for determining whether pressure is applied to the blood vessel under the second condition during measuring of continuous blood pressure.

Abstract: A differential voltage controlled oscillator comprises first and second transistors having opposite magnitudes and directions of currents flowing to a third electrode from a second electrode corresponding to a voltage between first and second electrodes; and a resonance circuit coupled to the second electrodes of the first and second transistors and controlling a frequency of an oscillation signal corresponding to a control voltage. The second electrode of the first transistor is coupled to the first electrode of the second transistor to form a first output terminal, the first electrode of the first transistor is coupled to the second electrode of the second transistor to form a second output terminal, and the third electrodes of the first and second transistors are coupled to first and second powers.

Abstract: A method for minimizing handoff latencies when a handoff is performed in a wireless network. An access point (AP) or base station associated to a current wireless station (STA) allows information required for a reassociation to the STA to be propagated to handoff-capable neighboring APs or base stations. When the STA moves, a neighboring AP or base station performs the reassociation to the STA on the basis of context. When a handoff procedure is performed, the time taken to receive context of a corresponding STA is reduced, such that a fast handoff can be implemented.

Abstract: A quadrature VCO comprises: a first delay cell including a first differential VCO coupled between a power supply and a first current source; and first and second coupling transistors that each include a first terminal, a second terminal coupled to the power supply, and a third terminal, and that vary a current flowing from the second terminal to the third terminal according to quadrature-phase signals applied to the first terminal; and a second delay cell including a second differential VCO coupled between a power supply and a second current source; and third and fourth coupling transistors that each include a first terminal, a second terminal coupled to the power, and a third terminal, and that vary a current flowing from the second terminal to the third terminal according to in-phase signals applied to the first terminal.

Abstract: The present invention relates to a length-adjustable golf putter primarily for use in putting a ball that is on green into a hole in a golf match. The invention is particularly for solving problems generated in case of short putting. When a player uses a long putter for short putting, gap between a bottom of green and an eye of a player is widened and range of vision is opened out, which lowers concentration, causing a problem that a putting line is not read exactly. Accordingly, an object of the present invention for eliminating mistakes originated from such problem, is to provide a putter whose length can be adjusted depending on putting distance, thereby achieving high putting success rate.

Abstract: The present invention relates to a golf club head with a multiple dimpled face. The present invention provides golf club head having a neck 12 to which a club shaft is connected, a bottom sole 14, a top edge 16, and a face 18, wherein the face 18 is provided with a number of dimples 20 in the form of circle.
