Abstract: PURPOSE:To prevent seizure and to decrease driving power loss by controlling the viscosity among the parameters of the number of revolutions of bearings, bearing load and the viscosity of a lubricating oil according to the number of revolutions of the bearings and bearing load determined as a result of operations. CONSTITUTION:The lubricating oil delivered from a tank 4 by a pump 5 is cooled to a prescribed temp. by a cooler 6 and is supplied to the bearing parts of backup rolls 2, 2', from which the oil is returned to a tank 4 and is thus circulated. The bearing load P, the number N of revolutions of bearings and the temp. of a lubricating oil detected by a screw-down force detector 8, a speed detector 9 of a work roll 3 and a thermometer 10 for the lubricating oil are inputted to a calculator 11 which calculates such a lubricating oil temp. at which ZN/P (Z: the viscosity of the lubricating oil) attains about 2.5. The signal obtd. from the difference between the actually measured temp. and calculated temp. is outputted to a flow rate regulating valve 12 to control the water flow rate of a cooling water pipe 13 thereby controlling adequately the ZN/P. The specified film thickness of the lubricating oil for the roll bearing is thus maintained constant.

Filed: 1981-08-17
Abstract: PURPOSE:To shorten the length of the part of a reflector, by providing the reflector for totally reflecting a surface acoustic wave on a surface acoustic wave propagation medium. CONSTITUTION:Onto the circumferential part of a surface acoustic wave propagating medium 1, a thin film substance 5 whose speed V2 becomes faster than a speed V1 of a surface acoustic wave on the medium 1 is made to adhere as a reflector.

Title: On-load tap changer
Inventor: KUBO MOTOHARU
IPC: H01F29/04
Filed: 1985-06-14
Abstract: PURPOSE:To eliminate maintenance and inspection works by detecting the moving distances of a movable arm contact or a driver of the contact by a moving distance detector provided in parallel with the moving direction of the contact, thereby enabling the inspeation of the consumed amount of the contact from the exterior. CONSTITUTION:As a movable arc contact 5 moves in a direction for contacting a stationary arc contact 4, the position where a light emitted from a light emitting unit 6a is shielded by the contact 5 alters. As a result, the position of the light read out by a photoreceptor 6b changes,and the moving distance of the contact 5 is detected. When the contact is then consumed, the thicknesses of the both contacts 4, 5 decrease. When the both thicknesses arrive at the managing limit value, a consumed amount discriminator displays the necessity of arc contact exchange.

Title: Stirring column type polymerizer
Inventor: SHIMADA TAKAFUMI
IPC: B01F7/16
Filed: 1987-05-27
Abstract: PURPOSE:To make it possible to produce continuously a polymer with high performance, by combining a cylindrical vessel, a rotating shaft, stirring means, and means of partitioning the vessel longitudinally so as to provide specific actions, thereby increasing the mixing effect. CONSTITUTION:Planar wings 9 are moved in the direction indicated by arrows 11 by the rotation of a rotating shaft 5, and a fluid which has been excluded by the movement of the wings 9 is formed into a large current along the inner circumferential section as indicated by arrows 12. Since the flow speed of the circulating current is higher than the moving speed of inclined wings 10a, 10b, and 10c, the circulating current rotates to pass these inclined wings, and therefore the circulating current is forced to be pushed up relatively by inclinations 10 to moved upwardly. On the other hand, since the fluid near the wall of the vessel moves only gently circumferentially as indicated by arrows 13 under the influence of viscosity resistance from the wall, the fluid is forced to be pushed down by the movement of the inclined wings 10 to be moved downwardly. Thus, an ascending current is formed in the inner circumferential section and a descending current is formed in the outer circumferential section, thereby forming a virtically circulating current.

Title: Towing winch
Inventor: SATO KENJI
IPC: B63B21/16
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To absorb the fluctuation in tension during the towing without using a rope for towing by selectively feeding a high pressure from a hydraulic pump to drive circuits of two hydraulic motors for traction drum, and controlling the towing tension of the rope to a prescribed value by an accumulator. SOLUTION: If the rope tension is temporarily increased, hydraulic motors 10, 11 are reversed by the load, and the rope is delivered to avoid excessive load. Though the working fluid flows in drive circuits 40B-40A, 46B-46A, it is absorbed by an accumulator 33. On the other hand, when the tension is temporarily reduced, the motors are driven in the direction to wind the rope and slackening is absorbed. The working fluid flowing in the drive circuits 40B, 46B is absorbed by an accumulator 35 of low pressure through low accumulation circuits 57, 58. The tension on the rope is kept constant according to the set pressure of the accumulator 33, and the fluctuation in tension during the towing is absorbed and mitigated.
