Disclosed herein is a copper-plated wire for gas-shielded arc welding. In the copper-plated wire, wire surface, from which a plated layer is removed, has a prominence and depression () shape on a circumference of a cross section in a direction of 90 degrees to a length of the wire, such that a ratio (dr/di) of an actual circular arcs length (dr) to an apparent circular arcs length (di) is in the range of 1.015-1.815. The wire has the prominence and depression () shape in a longitudinal direction of wire, such that a ratio (lr/li) of an actual measured length (lr) to an apparent measured length (li) is in the range of 1.015-1.515. The wire has improved surface characteristics of wire, so that adhesion between a substrate wire and a plated layer becomes excellent during copper plating on the wire surface, thereby remarkably enhancing the rust resistance and the feedability of wire in comparison to the conventional technology.

A tuning fork vibratory MEMS gyroscope for sensing angular velocity and angular acceleration generated due to the rotation of a movable body. The tuning fork vibratory MEMS gyroscope includes an external fixed support portion formed on a substrate; a plurality of external elastic members; first and second external frames respectively including driving combs; first and second driving electrodes respectively including comb drivers; first and second internal elastic members respectively including a plurality of spring members; first and second internal frames respectively including sensing combs; and first and second sensing electrodes respectively including comb sensors. The tuning fork vibratory MEMS gyroscope withstands a noise at a peripheral area, is driven at the external portions of internal frames, is sensed at the internal portions of the internal frames, and comprises the elastic members having a wine glass shape, thereby being more stably operated.

This invention identifies the economic benefits of living in a foreign country, where the cost of living is a fraction of the cost of living in the U.S., for retirees. Specifically, the method addresses the needs of those retired homeowners who will consider living abroad only a portion of the year while keeping their current homes as primary residences. A computer-implemented method determines the amount saved from living abroad for part of year for retirees who would buy a second home in a foreign country financed by reverse mortgages. Clearly, the level of saving or benefit depends crucially on the price of the second home in the foreign country, the difference between two countries' living expenses, and the number of months retirees plan to stay in the foreign country, among other inputs. Higher the amount saved, the more likely the retirees in high living-cost areas in the U.S. look into this option of living abroad, particularly those first-generation immigrant senior citizens. The method also addresses assessing the feasibility of developing residential communities in foreign countries for the U.S. senior citizens by developers. Specifically, given the cost of developing such communities abroad, the method determines the minimum threshold of living expense in the U.S. This minimum threshold of living expense in the U.S. will, in turn, determine the market segment or client base in the U.S., which the developer can target.

This invention relates to retirement communities. Specifically, a computer-implemented method and system enhances retired homeowners' accessibility to the retirement community on time-sharing basis and broadens the client base for the management and/or developers of such communities. The method particularly addresses the needs of those retired homeowners who will consider joining a retired community only a portion of the year while keeping their current homes. It determines the affordability of retirement community living on a time-sharing basis for retired homeowners, using reverse mortgages. The method also addresses the needs of developers of retirement community projects. It does a break-even analysis of the project under different scenarios, enabling a developer to assess the project's feasibility.

Disclosed is a lithium secondary battery comprising a cathode (C), an anode (A), a separator and an electrolyte, wherein the battery has a weight ratio (A/C) of anode active material (A) to cathode active material (C) per unit area of each electrode of between 0.44 and 0.70, and shows a charge cut-off voltage of between 4.35V and 4.6V. The high-voltage lithium secondary battery satisfies capacity balance by controlling the weight ratio (A/C) of anode active material (A) to cathode active material (C) per unit area of each electrode. Therefore, it is possible to significantly increase the available capacity and average discharge voltage of a battery using a lithium/cobalt-based cathode active material, which shows an available capacity of about 50% in a conventional 4.2V-battery. Additionally, it is possible to significantly improve battery safety under overcharge conditions, and thus to provide a high-voltage and high-capacity lithium secondary battery having excellent safety and long service life.

Disclosed herein is a surface treatment oil for treating the surface of a welding wire. The surface treatment oil comprises at least one alkali metal compound and/or an alkaline earth metal compound, a Zn compound, and a hydrocarbon compound wherein the hydrocarbon compound contains at least two functional groups selected from the group consisting of ester, carboxylic acid, alkane and sulfonic acid groups. Further disclosed is a welding wire surface treated with the surface treatment oil. The surface treatment oil can provide good rust resistance, wear resistance, arc stability and wire feedability to a welding wire when being applied to the surface of the welding wire.

Handover execution and communication resumption in a wireless access system is provided. Performing a handover includes communicating with a serving base station through a first communication link and receiving from the serving base station, handover information associated with at least one candidate target base station. The method also includes transmitting handover indicator to the serving base station indicating a handover operation to a selected target base station and performing a ranging procedure with the selected target base station to establish a second communication link with the selected target base station while maintaining the first communication link with the serving base station. The method also includes being released from the serving base station in response to a handover complete status message from the selected target base station to the serving base station, or resuming normal communication with the serving base station if the handover fails with the selected target base station.

The present invention is an electrolyte for a lithium ion rechargeable battery and a lithium ion rechargeable battery that includes the same. More particularly, the present invention discloses an electrolyte for a lithium ion rechargeable battery that provides excellent cycle life characteristics and high-temperatures storage stability and prevents a drop in discharge capacity of a battery at low temperature, and a lithium ion rechargeable battery including the same. The lithium ion rechargeable battery including the electrolyte provides improved cycle life characteristics and prevents the problems of a drop in discharge capacity at low temperature and high-temperature swelling through the formation of a stable SEI film at the initial charge cycle.
