Abstract: The present disclosure relates to a printed circuit board and a method of manufacturing the same. The printed circuit board includes: an insulating layer; a plurality of pads disposed on the insulating layer; and a plurality of insulating walls that are disposed on the insulating layer and cover side surfaces of the plurality of pads, respectively, but are not disposed on upper surfaces of the plurality of pads. The plurality of insulating walls are disposed to be spaced apart from each other on the first insulating layer.

Abstract: An apparatus for controlling a discharge pressure of a fluid includes: a pump configured to suck the fluid through an inlet or to discharge the sucked fluid through an outlet; a distributor connected to the pump and to an injection nozzle provided by a sensor and configured to distribute the fluid discharged from the pump to the sensor; and a controller. The controller is configured to control the pump to operate selectively in accordance with detection of contamination of the sensor and to control operation of the distributor to be forcibly delayed during operation of the pump such that the fluid distributed to the sensor, when detected as being contaminated, is controlled to reach a selected required discharge pressure of different required discharge pressures selected in accordance with water amount information and a degree of contamination of the sensor.

Abstract: A fishing rod includes an improved fishing rod including a tubular rod and a first plurality of multiple longitudinally extending, helical weavings intertwined with a second plurality of multiple longitudinally extending, helical weavings of a tow or yarn disposed on the tubular rod, the weavings defining a crossing interlocking pattern which provides high elasticity, excellent softness and super power control properties. The present invention is also directed to the method of manufacturing the fishing rod.

Abstract: A tubular fishing rod includes a plurality of multiple helical windings intertwined with a plurality of multiple reverse helical windings and its method of manufacture, whereby the resulting tubular fishing rod has high elasticity, excellent softness and super power control properties.
