摘要:
When supporting the handover from first road side equipment of a plurality of sets of road side equipment and second road side equipment that is adjacent to the first road side equipment to a vehicle, the first road side equipment generates a first channel seizing signal that is longer than that of the second road side equipment in a control channel of an N-th sync interval. The second road side equipment generates a second channel seizing signal that is longer than that of the first road side equipment in a control channel of an (N+1)-th sync interval.

摘要:
A cooperative communication method for vehicular communication is provided. The method in which when one vehicle transmits a signal to another vehicle, a signal of a transmission vehicle passes through a roadside device or a plurality of vehicles and thereafter signals having a plurality of paths are transmitted to a reception vehicle, and the reception vehicle combines and demodulates the signals received through the plurality of paths.

Disclosed are a reciprocating compressor and a refrigerating apparatus having the same, wherein a magnet bearing is inserted between facing surfaces between a cylinder block and a crank shaft and the magnet bearing so as to generate a magnetic force both in a shaft direction and in a radial direction, so that the cylinder block and the crank shaft can be supported both in the shaft direction and in the radial direction, thereby reducing a frictional loss due to an eccentric load of the crank shaft, and also, both magnets are disposed to overlap each other so as to prevent an increase in an input load due to the magnetic force between the magnets, resulting in further improvement of energy efficiency of the compressor.
摘要:
A detergent case which includes a liquid detergent accommodation space, a siphon pipe protruded upwardly from a bottom surface of the liquid detergent accommodation space, and a siphon cap surrounding the siphon pipe. The detergent case also includes a remaining water discharge hole formed on a bottom surface of the liquid detergent accommodation space, and an opening and closing unit to open and close the remaining water discharge hole due to buoyancy of a liquid accommodated within the liquid detergent accommodation space.
摘要:
Disclosed is a compressor capable of having an enhanced performance by sufficiently supplying oil to components where sliding occurs not only in a high speed driving mode but also in a low speed driving mode. The compressor may increase an oil supply amount in a low speed driving mode, but may restrict an oil supply amount when a rotation speed of a driving motor reaches a predetermined speed in a constant or high speed driving mode, by setting the number of turns of an external groove to be approximately 1.75, and by forming an oil feeder in a conical shape.
