Abstract: A composition includes a compound represented by Formula (1) and a pigment. In Formula (1), R1 represents an (m+n)-valent linking group, P1 represents a polymer chain which has a polyester repeating unit in a main chain, and of which a weight-average molecular weight is 1000 or more, P2 represents a polymer chain which is different from P1 and has a repeating unit derived from a monomer having an ethylenically unsaturated bonding group in a main chain, m represents a number of 1 to 9, n represents a number of 1 to 9, and m+n satisfies 4 to 18.

Abstract: A fuel supplying system includes a tank and a pump unit, which transfers fluid from the tank. The pump unit includes a first pump, a second pump, and a drive source. The first pump and the second pump are driven by the common drive source. The first pump, the second pump, and the drive source are structured as one unit. This reduces the size and simplifies the structure of the fuel supplying system.

Abstract: An electric motor that has a electric motor and a compression mechanism. The motor and the compression mechanism are accommodated in a single chamber. A single shaft functions as the output shaft of the motor and the drive shaft of the compressor.
