The invention relates to a time-alignment apparatus and a time-alignment method of a transmitter of a telecommunication system TELE. A control unit recognizes connection information outputted from an information output unit provided in each of the light emitting modules and varies the output current of the constant-current power supply. Notably, in the preferred embodiment, the group of target recipients is an opt-in list. Mobility was inversely proportional to the logarithm of molecular weight. This softener composition can endow cotton and cotton clothes in particular with a preferred softness, elasticity and feeling of dryness with small oiliness.
