A coil electronic component includes: a magnetic body comprising a magnetic material; a coil part embedded inside the magnetic body; and a magnetic layer disposed on a surface of the magnetic body.

Coil electronic component and manufacturing method thereof

A chip light emitting diode having a wide viewing angle, and a fabrication method thereof. The chip light emitting diode has a resin package sealing a light emitting chip which has at least one curved projecting part. The curved projecting part has a cross section which is substantially semicircular, or substantially or partially elliptical or parabolic. The curved projecting part preferably has a cross section which is comprised of a plurality of straight lines, an angle being formed between adjacent lines. The cross section is elongated to form a cylindrical outer surface of the resin package.

Chip light emitting diode and fabrication method thereof

Light emitting diode

A forced downshift control method for automatic transmissions, wherein, if shift signals of a forced 4-2 downshift are input, a first shift control solenoid valve (SCSV-A) is controlled to OFF; a second shift control solenoid valve SCSV-B is maintained in an OFF state for a predetermined period of time (t1) then controlled to ON; a third shift control solenoid valve (SCSV-C) is continuously maintained in an ON state, then is immediately controlled to OFF and first and second pressure control solenoid valves (PCSV-A) and (PCSV-B) are duty controlled. The method further includes performing a first duty control operation to complete shifting through control of the first pressure control solenoid valve (PCSV-A); performing a second duty control operation to complete shifting by performing a second open-loop duty control operation; performing a third duty control operation to complete shifting through control of the second pressure control solenoid vale (PCSV-A); performing a fourth duty control operation to complete shifting by performing a fourth open-loop duty control operation; performing a fifth duty control operation to complete shifting by performing a fifth open-loop duty control operation; and performing a sixth open-loop duty control operation, regardless of variations in power conditions, to complete shifting.
