摘要： PURPOSE:To eliminate the need of an actual 1/f fluctuation signal existing in the natural world and to easily generate a pulse train signal of a time interval having a 1/f fluctuation characteristic by reading successively plural kinds of numerals in accordance with a random number train, and sending out a pulse signal having a time interval set in advance in accordance with the respective numerals. CONSTITUTION:A time interval setting part 2 sets in advance time intervals T1 - T8 in accordance with plural kinds of numerals C1 - C8, respectively stored in advance in a random number store part 1. A control part 3 reads successively a random number train stored in the random number store part 1, and sends out a pulsative signal in accordance with a time interval Ti corresponding to a numeral Ci. That is, from the control part 3, the pulsative signal is sent out at every time interval T5, T3, T7 and T1 corresponding to each numeral C5, C3, C7 and C1. In such a way, a pulse train signal of a time interval having a 1/f fluctuation characteristic can be generated easily without necessitating an actual 1/f fluctuation signal existing in the natural world.

摘要： PURPOSE:To provide a device which can effectively cool a steel strip of a relatively low temp. without providing rubbing grazes to the surface and with easy temp. control by supporting afloat the approximately horizontally traveling steel strip with the fluid pressure of cooling water. CONSTITUTION:Floaters 2 are successively provided at proper intervals along the traveling direction of the steel strip 1 which is subjected to annealing, holding, quick cooling and overaging treatments in a continuous annealing furnace and is then drawn out of the furnace after cooling to about 250-200 deg.C so as to face the bottom surface of the steel strip. Slit nozzles 4 opened to incline respectively inward are provided at both ends in the longitudinal direction on the top surface of headers 3 constituting the bodies of the floaters 2 and baffle plates 5 are juxtaposed with the top surface the headers 3. Pressure water is supplied from supply pipes 6 to the headers 3. The steel strip 1 is going to sag by the own weight but the jets of the cooling water ejected in the crossing directions from the nozzles 4, 4 are forced between the top surfaces of the headers 3 and the bottom surface of the steel strip 1 and the static pressure of the fluid is generated therebetween. As a result, the steel strip 1 is supported afloat and is effectively cooled.

摘要： PURPOSE:To decrease the excessive thrust force acting on work rolls by providing power transmission devices which permit the movement of the work rolls in their axial direction in place of thrust bearing devices for the work rolls of a roll cross rolling mill. CONSTITUTION:A paired cross system is made into the construction wherein the thrusts of upper and lower work rolls 1, 2 are not supported. Power transmission devices 5, 6 which transmit torque and are adjustable in length, for example, splined shafts which absorb the axial movement of the work rolls, are provided. The upper work roll 1 and a backup roll 3 as well as the lower work roll 2 and a backup roll 4 are held in the positions where the axial centers are in parallel with each other and in this state the axial centers of the upper and lower paired rolls are crossed within the horizontal plane, and a plate material is rolled with such rolls. If relative slips are to arise in the axial direction between the work rolls and the plate, the rolls 1, 2 move axially so as not to apply any relative slip on the plate W.

摘要： PURPOSE:To prevent the generation of edge drops, etc. and to obtain products of good shapes by forming split type eccentric rolls for the backup rolls of multistage rolling mills and loading roll bending force upon the metal chocks of intermediate rolls. CONSTITUTION:In multistage cluster rolling mills, backup rolls 4 are split to plural rolls in the direction intersecting orthogonally the axial direction of stationary shafts 5a and the bearings of the split rolls are off-centered. Crowns are adjusted by the entire part of the rolls 4. Crowned parts are provided in the end parts of upper and lower work rolls and intermediate rolls 3 and are moved symmetrically in an axial direction. Further, means 11, 12 for loading roll bending force are provided to metal chocks 7 for the intermediate rolls to transmit the rugged shapes formed by the backup rolls effectively to the work rolls 2. By such mechanism the products having less generation of edge drops, etc. are obtained.
