IPC: G12B9/08
Filed: 1993-12-06
Abstract: PURPOSE:To cope with the grade of amplitude so as to isolate vibration in a short time with good responsiveness and desirable vibration isolating performance. CONSTITUTION:A sensor is fitted to a surface table with precision mechanical equipment. When vibration with amplitude of the fixed value or more is detected by the sensor, a detection signal is outputted, and the driving part of variable damping mechanism is driven to operate an ER damper 9. The ER damper 9 is formed of a suspended member 10 fixed to the surface table, and a storage member 11 surrounding the suspended member 10 and storing an electroviscous fluid 13 therein. The opposed faces of the suspended member 10 and storage member 11 are provided with opposed electrodes 14, and when the desired voltage corresponding to the detection signal of vibration is applied to the opposed electrodes 14, the electroviscous fluid 13 comes to have desired viscosity so as to damp the vibration of the surface table. When the amplitude becomes the fixed value or less, vibration is isolated by the ER damper 9 with a normal damping constant without putting the driving part in action. Amplitude is thereby coped with, without needing a large-scale device, and vibration can be isolated with desirable vibration isolating performance.

IPC: G11B5/09
Filed: 1991-10-23
Abstract: PURPOSE:To shorten a time required for optimization by detecting an optimized value in a state that a magnetic tape is wound around a rotary drum at a starting time of operation.

Title: Reservoir controlling device
Inventor: TAKABE KOICHI
IPC: H02P7/00
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To prevent a remaining quantity in a reservoir from becoming zero, by providing a speed adjusting circuit receiving a line speed signal and a speed set value, for adjusting a control signal to an inlet section control circuit. SOLUTION: Since a reservoir 7 stores therein a quantity corresponding to a time for replacing a wind-up shaft during normal operation, the shaft is replaced at an inlet speed which is held at a set speed. Meanwhile, if a delay in operation occurs during replacement of the wind-up shaft so that the time for the replacement is extended, a sheet 1 is fed from an inlet section 2 by a quantity corresponding to a delay. In this case, an inlet speed calculating circuit 15 delivers a speed retardation signal to an inlet section 2 so as to prevent the remaining volume in the reservoir 7 from becoming zero. Further, the inlet speed is retarded by a speed adjusting circuit 13 to a value with which the remaining quantity in the reservoir is prevented from becoming zero upon completion of the replacement of the wind-up shaft.  Thus, it is possible to stop the line without the remaining quantity in the reservoir 7 becoming zero.
