Title: Method for preventing necking
Inventor: NOMURA NOBUAKI
IPC: B21C47/02
Filed: 1990-12-03
Abstract: PURPOSE:To prevent necking at the forward end of a strip by starting to reduce the speed of a hotline table before the forward end wraps around a mandrel and controlling the speed at less than the transporting speed of the strip. CONSTITUTION:When the forward end of the strip 2 is detected by a detector 7 which is installed on a finishing side at 10 m from a pinch roll 4, the speed of the hotline table 3 is reduced at 30% less than the transporting speed of the strip 2 as a target value, and at the time of wrapping around the mandrel 5, the speed of the table is reduced at 10% less than the transporting speed of the strip 2. Also, in three sec after the completion of wrapping around the mandrel 5 by the strip 2 is detected through the rise of the mandrel current, the speed of the hotline table is restored to the transporting speed of the strip 2. Consequently, the necking is reduced, and the margin area of a product is made small. Also, by taking up the strip while placing a tension to the back, the bending of the forward end of the strip is corrected.

IPC: G06F3/02
Filed: 1990-12-03
Abstract: PURPOSE:To obtain the collation result of input data immediately at its input point of time by checking the contents of the data which is inputted from the portable terminal by collation. CONSTITUTION:The collation data master file 3 of a host device 1 contains keys for identifying input objects, data for collating the input data, and the classifications of the data. When the data is inputted from the portable terminal 2, a message of the collation result based upon the input data and its classification is displayed on condition that the data corresponding to the input data is present in the collation data file 4. When the corresponding data is not present in the file 4, the input data is displayed. When the input data is not written according to a judgement of the displayed contents, a canceling process is performed. In the other case, the input data is written in an input data file 5 on the terminal 2. Therefore, the collation result of the input data can be obtained immediately when inputted.

The radiant heater (30) is ring-shaped with its dimensions and distance from the target surface preferably defined to provide radiant energy to a target surface (4), with the ate of energy received per unit area of the target surface (4) being substantially uniform. A frusto-conical ring-shaped radiant heater (40) is also disclosed, which may be disposed closer to the surface (4) to provide improved efficiency of heat transfer in a uniform fashion. A cooling element similarly shaped is also disclosed, which operates in the same manner to uniformly transfer radiant heat from the target surface (4). Zoning of the ring-shaped radiant heaters (30), to allow for non-uniform radiant energy emission to the target surface, is also disclosed. Monitoring of the temperature of the target surface (4) is done by way of infrared sensors (34). For monitoring of cool temperatures, a second infrared sensor (36) is directed to the radiant heater, so that compensation for reflection of the radiant heat from the surface (4) may be accomplished. <IMAGE>
