The present disclosure relates to an electric vehicle charging connector, which includes a cooling chamber through a cooling fluid passes to cool an electric vehicle charging cable and is configured to connect in the cooling chamber a terminal of the electric vehicle charging connector and a conductor of the electric vehicle charging cable so as to quickly cool heat generated on the terminal of the electric vehicle charging connector and a conductor connection part of the electric vehicle charging cable in the cooling chamber, and to collect the cooling fluid from the cooling chamber to an electric vehicle charger, and an electric vehicle charging assembly.

Electric vehicle charging connector and electric vehicle charging assembly comprising same

The present disclosure relates to an electric vehicle charging cable, in which a cooling fluid is used to efficiently cool heat generated during charging of an electric vehicle, a thermally conductive material is added as well as the cooling fluid to improve cooling performance, thereby preventing damage to inner components due to heat, safety accidents such as fire are prevented, and a diameter of the cable is minimized.

Electric vehicle charging cable

The present disclosure relates to an electric vehicle charging connector, in which a heat sink is provided to effectively cool the electric vehicle charging connector during charging of an electric vehicle, heat generated in an interface between an electric vehicle cable and a conductor of a connector connection unit is quickly absorbed by the heat sink, and a cooling fluid flows in the heat sink to cool an electric vehicle charging cable and is collected in an electric vehicle charger after cooling of the heat sink, and an electric vehicle charging assembly.

A color generation deviceaccording to the present invention has a light source, and also has a linear polarizing means, a first birefringence mediumand a second birefringence mediumattached to each other in sequence in front of the light source. A display meansis provided which is distanced from the linear polarizing means, the first birefringence mediumand a second birefringence medium. The first birefringence meansis arranged for the principal axes thereof to be at angle of 45&#xb0; or &#x2212;45&#xb0; with respect to the polarization direction aof the linear polarizing meansand the second birefringence mediumis arranged for the principal axes thereof to be the same as or perpendicular to polarization direction aof the linear polarizing meansand quarter wave plate is used therefor.

Color generation device having first and second birefringence media for generating improved color by increasing tendency of linear-polarization and method for the same

A display device includes a reflective base member, a first light polarizing film disposed on the surface of the base member, a light source, a second light polarizing medium receiving light from the light source and emitting polarized light towards the first light polarizing film, a birefringence medium positioned between the second light polarizing medium and the first light polarizing film, and means for changing the direction of polarization of the second light polarizing means.

Display device having polarized light source

A polarization illumination systemaccording to the first invention of the present patent application includes an illumination means having light source means, polarizing meansfor receiving and polarizing light emitted from the light source means, a birefringence mediumfor receiving and double refracting the light emitted from the light source means and transmitted through the polarizing means. Illumination space S to which the light of the illumination means is illuminated has a polarized reflection objectthat reflects an incident light in a way that the reflected light partly or fully polarized.

Polarization illumination system

The present invention provides an apparatus for sound comprising a sound source generating unit for generating an electric signal from a sound source, N (N&#x2267;2) amplifiers which are connected in series so that the output part of one amplifier is connected with the input part of the other amplifier and one of them is connected with the sound source generating unit, and 2N speakers which are respectively connected with left and right output parts of each of the N amplifiers. According to one aspect of the invention there is formed a multiple stereo imaging including a first stereo imaging, a first mono imaging, a second mono imaging and a second stereo imaging generated by the first mono imaging and the second mono imaging.
