摘要:
A secondary battery includes first and second collecting plates branching out from an electrode terminal, and first and second electrode assemblies rolled up in a jelly-roll type unit, the first electrode assembly having a first non-coating portion adhered to the first collecting plate, the second electrode assembly having a second non-coating portion adhered to the second collecting plate, and the first and second collecting plates being on facing surfaces of respective first and second non-coating portions. The first non-coating portion is spaced apart from a roll center of the first electrode assembly by a first predetermined distance along a direction directed away from the second non-coating portion, and the second non-coating portion is spaced apart from a roll center of the second electrode assembly by a second predetermined distance along a direction directed away from the first non-coating portion.

A method of determining a relation between search queries, includes: maintaining a database comprising a search session and a record about a search query which is received from a user terminal during the search session; recording and maintaining click rate information for each of the search queries in a predetermined storage unit; generating total search session number information by counting a total number of search sessions which is set during the time interval generating first search session number information by counting a number of search sessions where a first search query is received during the time interval, and generating second search session number information by counting a number of search sessions where a second search query is received during the time interval, by referring to the database; generating third search session number information by counting a number of search sessions where the first search query and the second search query are received during the time interval, by referring to the database; generating conditional probability information by using the first search session number information and the third search session number information; generating correlation information by using the total search session number information, the first search session number information, the second search session number information, and the third search session number information; querying click rate information of the second search query by referring to the storage unit; and determining a relation between the first search query and the second search query, based on the conditional probability information, the correlation information, and the click rate information.
摘要:
A probe support carriage for use during probing an electrical device includes a body, means for supporting and positioning the body, a plurality of flux sensors and a position sensor. The body has a first end and a second end. The plurality of flux sensors are operatively connected to the body. Each flux sensor includes a probe having a core and a coil. The core includes a material having high initial permeability and high resistivity characteristics. The probe is adapted to being supported so that a sensing portion of the core is maintained in a contact-free spaced relationship between a predetermined surface of the electrical device and the sensing portion of the core. The position sensor is adapted to determine position along a longitudinal axis of the electrical device.

In a method of coating a photoresist, the photoresist may be provided to an upper surface of a rotating wafer. A hovering solution may be injected to an edge portion of the photoresist under a condition that the hovering solution may be hovered with respect to the edge portion of the photoresist with an air layer being interposed between the hovering solution and the edge portion of the photoresist to limit and/or prevent a bead of the photoresist from being formed on an edge portion of the upper surface of the wafer. Thus, the photoresist having a uniform thickness may be coated on the upper surface of the wafer to improve a yield of a semiconductor device by increasing an effective area of the edge portion of the wafer.
