The present invention uses a nitrogen-containing organic compound to be reacted with an alkyl sultone to obtain a zwitterion compound. Blocks of the center land portions include one open sipe extending in the tire width direction so as to partition the blocks in the tire circumferential direction, and three or more closed sipes disposed in each of the regions of each of the blocks partitioned by the open sipe. It is possible to determine the zone in which the control device is located by using the position of the control device. An image of the area of the map in the rotated frame of reference is rendered on the client device, based on the downloaded map data. The method of use may include the steps of placing a feedstock into an upper portion of the refractory stack, measuring the temperature of each columnar cavity, and adjusting the flow of oxygen to a particular columnar cavity to maintain the temperature of the particular columnar cavity within a particular range.
