The present invention relates to methods and arrangements for reducing the time delay associated with the initialization of a data transfer in a Universal Mobile Telecommunications Systems terrestrial radio access network. A material in a quantity greater than shot weight Qout is fed continuously into the cylinder until the upper limit is reached, while the material in a quantity less than the shot weight is fed into the cylinder until the lower limit is reached, thereby automatically maintaining the quantity of material detained in the cylinder within the range between the upper and lower limits. The heater casing includes a blowing port configured to narrow and blow warm air heated with the heaters to a transportation path outside the heater casing in a direction along the transportation path. The Al content in the outer layer is at least 20 atomic percent. The setting unit sets a maximum value for determining whether the second write process succeeds or fails to a first value when the change process is executable, and sets the maximum value to a second value when the change process is not executable.
