Filed: 2002-03-08
Abstract: <P>PROBLEM TO BE SOLVED: To provide a recording apparatus capable of installing a rotation detecting means for feeding control of a recording medium even in the case where the space provided in the apparatus is small.  <P>SOLUTION: A rotation detecting means 172 for feeding control of a recording medium is mounted on intermediate gears 173c, 173d comprising a feeding wheel row 173.

Title: Method for mixing pulverized coal to be blown into blast furnace
Inventor: OTA TAKESHI
IPC: C21B5/00
Filed: 2002-03-28
Abstract: <P>PROBLEM TO BE SOLVED: To simultaneously solve such problems of both abrasion and plugging that a hard pulverized coal employed for being blown into a blast furnace, abrades the pipe wall of a transport pipe, and a soft pulverized coal clogs in the transport pipe due to the viscosity.  <P>SOLUTION: In the figure, ○ indicates excellence, μ plugging, and Δ abrasion, of which the latter two signs mean failure. This method is characterized by mixing different sorts of pulverized coals so as to satisfy the condition of 3X-105≤Y≤3X+50. Then, the method makes a protective layer of an appropriate amount of the pulverized coal adhere onto the pipe wall of a transport pipe, and restrains the pipe wall from being abraded due to the protective layer. The pulverized coal simultaneously has an effect of grinding the pipe wall as well, because of having an appropriately lowered Hardglove index. For that reason, the method prevents both plugging and the abrasion for a long term, because the pulverized coal balances growth of the protective layer in the pipe with an action of grinding the protective layer.  <P>COPYRIGHT: (C)2004,JPO
