A surface treatment solution for a plated steel sheet to be hot-pressed comprising a ZnO aqueous dispersion (A) and a water dispersible organic resin (B), wherein the ZnO aqueous dispersion (A) comprises water and ZnO particle size having 50 to 300 nm particles, the water dispersible organic resin (B) has a 5 to 45 mgKOH/g acid value and 5 to 300 nm emulsion particle size, and a mass ratio (W/W) of a mass of ZnO particles in the ZnO aqueous dispersion (W) to a mass of solid content of the water dispersible organic resin (W) is 30/70 to 95/5.

Surface treatment solution for plated steel sheet to be hot-pressed

A communication apparatus comprises a regular optical transceiver that generates regular subcarrier signals serving as subcarrier signals, a narrowband optical transceiver capable of generating narrowband subcarrier signals serving as subcarrier signals each having a narrower frequency band than the regular subcarrier signal, and a subcarrier configuration determiner that determines the configuration of a plurality of subcarrier signals in a super-channel signal, based on information on the number of optical filter stages to pass through. The regular optical transceiver shifts the positions of the regular subcarrier signals in the super-channel signal, according to optical frequency shift amounts indicating shift amounts of the plurality of subcarrier signals represented by the configuration determined by the subcarrier configuration determiner. The narrowband optical transceiver shifts the positions of the narrowband subcarrier signals in the super-channel signal according to the optical frequency shift amounts.
