The present invention relates to a powder coating composition comprising an epoxy resin, a curing agent, a pigment, and a catalyst, wherein the pigment comprises an extender pigment having an average particle size of 1.0 μm to 8.0 μm, and the catalyst comprises an aliphatic imidazole compound and an aromatic imidazole compound.

Powder coating composition

A motor unit for a sunroof is proposed. The motor unit may include a lower housing, an upper housing, a bush, a worm wheel, a drive shaft, a pinion gear, the washer, and a bottom cover. Particularly, contact between the drive shaft and the bottom cover may be prevented, and the worm wheel may be configured to be in contact with the washer and he bush. Accordingly, different kinds of noise may be prevented from being generated according to opening and closing directions of the sunroof.

Motor unit for sunroof

An electric actuator assembly is proposed. The electric actuator assembly includes: a brush card assembly provided with a brush card part in which a plurality of terminals is molded through insert injection molding; a motor assembly coupled to the brush card assembly and electrically connected thereto; a housing provided with a coupling part into which the brush card assembly is inserted, having a circuit board provided with a connector, and having a gear assembly for receiving power from the motor assembly and transmitting the power to outside, the circuit board and the gear assembly being installed in the housing, wherein terminal holes through which the plurality of terminals passes and a coupling hole into which a part of the brush card part is inserted are separately provided in the coupling part.

Electric actuator assembly with a brush card assembly

Provided is a method and apparatus for selecting an airborne position reference node. A weight center coordinate of the repeaters is calculated by using position coordinates of repeaters, a plane having a vector connecting the weight center coordinate and a position coordinate of a user as a normal vector is determined, and the position coordinates of the repeaters are orthographically projected onto the plane. A certain number of repeaters located farthest from the weight center coordinate of the repeaters are selected to be airborne position reference nodes, on the basis of the orthographically projected coordinates of the repeaters and the weight center coordinate.

Apparatus and method of selecting airborne position reference node

The present invention provides a powder coating composition comprising a diisocyanate-modified bisphenol A epoxy resin, a curing agent, an auxiliary curing agent, an enhancer, and an extender pigment, wherein the auxiliary curing agent comprises an alkanolamine-modified epoxy polyol resin.
