Abstract: The present invention relates to a heater for an electric vehicle, including: a radiator disposed in the electric vehicle to radiate heat when power is supplied thereto; a power supply part disposed in the electric vehicle to supply the power to the radiator; and a controller for controlling the operation of the power supply part, wherein the radiator is made of a carbon material and emits far infrared light therefrom when the power is supplied from the power supply part thereto. According to the present invention, the radiator emits the far infrared light to enable the heat to be applied directly to a user's body, thereby reducing an amount of power consumed unnecessarily and providing high thermal comfort for the user.

Abstract: A heat generation diving suit according to an embodiment of the present invention includes: a clothes unit made of a material having a waterproof function, and configured to cover at least a part of a user's body; a power transmission unit having a waterproof function, and configured to wirelessly transmit power of a battery unit; a power reception unit provided in the clothes unit, and configured to have a waterproof function, attach and detach the power transmission unit, and receive power wirelessly transmitted from the power transmission unit; and a heat generation unit configured to emit heat using the power supplied from the power reception unit.

Abstract: A conditioner for polishing pad and a method for manufacturing the same are disclosed. The conditioner comprises a substrate having formed with a plurality of geometrical protrusions of an uniformed height on at least one of its sides, and a cutting portion having a diamond layer of an uniformed thickness formed substantially on a whole surface of the side of the substrate having the geometrical protrusions. The geometrical protrusions have a flat upper surface or the upper surface may comprise a plurality of smaller geometrical protrusions formed by recessed grooves. The substrate is made from ceramic or cemented carbide materials and has a shape of a disk, a plate having multiple corner, a cup, a segment, or a doughnut with flattened upper and lower surfaces. The conditioner may further comprise a body portion being fixedly attached to the substrate at a side opposite to the side having formed with geometrical protrusions for linking the cutting portion to conditioning equipment.
