Filed: 1985-06-27
Abstract: PURPOSE:To improve an accuracy of estimating a spindle torque and to roll on optimum condition by obtaining a ratio of an actual value to an estimated value and correcting a pass schedule based on said ratio. CONSTITUTION:A torque meter 14 is equipped on a surface of the spindle 12 of a working roll 10 and the data collected by strain gauges of the meter are transmitted by a wireless transmitter 16.

On the arithmetic unit 22, the ratio of the actual value to the estimated value with said signals is obtained, then based on the ratio, a correction of the estimated value is obtained. And then, the next estimating torque value multiplied by the ratio makes the estimating torque value of the subsequent pass. In this way, as the pass schedule is corrected, the accuracy of estimation is improved and the rolling is performed on optimum condition.

Filed: 1984-07-06
Abstract: PURPOSE:To improve reaction efficiency for forming glass film remarkably in the titled process wherein starting materials for forming glass is fed to plasma flame through an introducing pipe for the starting materials, by regulating the attaching angle of said introducing pipe. CONSTITUTION:O2 is fed to high frequency plasma torch 1 in the arrow direction to generate plasma flame.

Title: Regeneration of cationic exchange resin
Inventor: HENMI YUKIO
IPC: C02F1/42
Filed: 1992-06-02
Abstract: PURPOSE:To prevent a material used for a nuclear reactor primary system from becoming broken due to stress corrosion crack caused by the deterioration of water quality under the effect of sulphuric acid remaining in a furnace water by using nitric acid as a regenerating chemical for a cationic exchange resin filled in a desalting tower such as in recovered water purification system reactor water purification system attached to a boiling water-type nuclear power plant. CONSTITUTION:Sulphate ion accelerates the rate of stress corrosion crack which erodes a corrosion film formed on the surface of austenite stainless steel. On the other hand, nitrate ion, if normally 100ppb max in concentration, maintains the corrosion film to be in a passive state, depending on the temperature conditions of BWR reactor water. In addition, nitrate ion brought into the reactor becomes ammonium, if hydrogen is injected. These chemicals rather tend to inhibit the stress corrosion crack. Therefore, it is possible to secure the life of a material calculated based on a design value.

IPC: G03G21/14
Filed: 1977-11-28
Abstract: PURPOSE:To smoothly start the paper feeder by intermittently controlling the connection of a clutch for transmitting driving power according to the count values of timing pulses. CONSTITUTION:When the pulse which are outputted by a timing pulse generator 30 constituted by a slit disc rotating intearqlly with a motor 10 and a light emitting  element and photo detector and is generated according to the revolutions of a photosensitive drum 11 are applied to the CPU 1 of a microcomputer 5, these are counted  by the counter of a RAM 3 and interruption is performed in the process which sets  the optimum conditions through checking of the operating condition, ambient conditions, abnormalities, etc. of a copying machine 6 according to the program being read from a ROM 2 by way of the RAM 3. The interruption program is then read out from the ROM 3. This causes the intermittent connection of the clutch for driving the paper feeder to be so controlled that the continuation time becomes gradually longer according to the count value of the counter of the RAM 3, so that the clutch is perfectly coupled at the time when the optimum set conditions via the CPU 1 are set. Hence, the starting of the paper feeder by way of the clutch is  accomplished not abruptly but slowly and the feeder is smoothly started.

IPC: H01M2/16
Filed: 1993-06-14
Abstract: PURPOSE:To provide a separator for an alkaline battery capable of being used over a long period for repeated charges and discharges by using graft- polymerized vinyl sulfonic acid soda as a side chain. CONSTITUTION:An ethylene-vinyl alcohol copolymer (at the copolymerization ratio of 20% for vinyl alcohol) used as a principal chain and vinyl sulfonic acid soda used as a side chain are graft-polymerized to form a polymer resin, and it is solved in a 5%-aqueous solution of toluene. A nonwoven fabric sheet is impregnated with this solution, then it is dried to form a separator. The graft ratio of 3-10% is most preferable, and a good hydrophilic property is not obtained at less than 3% or at 10% or above. The graft-polymerized vinyl sulfonic acid soda supplements the deterioration of the chemical resistance of the ethylene-vinyl alcohol copolymer by oxidation decomposition in a battery, and a separator for the alkaline battery having little capacity reduction and capable of being used over a long period for repeated charges and discharges can be obtained.
