Title: Device and method for positioning optical fiber and other elastic member
Inventor: HAYES ROBERT R
IPC: H04B10/118
Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To reduce inertia, to operate a device with low driving power and to miniaturize and lighten the device by giving charge to the free end part of an elastic member, deciding at least one electric field crossing the free end part and moving the free end part to a position where the force of the electric field against the charge and the internal restoration power of the elastic member become smooth. SOLUTION: A positioning device 128 has the capacitance member of a conductive sleeve 136 covering the optical fiber 122 and it receives and accumulates the charge. The polarity of a voltage source 140 is decided so that the positive charge is arranged on the sleeve 136 and the polarity generates the electric field crossing the sleeve 136 and the charge. Force is induced for the positive charge by the electric field and the sleeve 136 is horizontally displaced on a position 136A toward the electrode. The position 136A is a position where the deflection force of the electric field against the charge in the sleeve 136 becomes equal to the restoration force of the elastic optical fiber.

Title: Vibration absorbing device and aligner
Inventor: TAKAHASHI MASATO
IPC: G03F7/20
Filed: 1996-09-03
Abstract: PROBLEM TO BE SOLVED: To improve the external vibration suppressing (damping) effect of a vibration absorbing device without receiving any influence from the movement of the center of gravity of the device caused by the movement of a stage. SOLUTION: When a stage moves, the movement of the stage is measured by means of interferometers 30X, 30Y, and 30R and a command value (such a command value that corrects the inclination of a vibration absorbing table caused by the movement of the center of gravity of the stage when the stage moves) which is K times as large as the outputs of the interferometers 30X, 30Y, and 30R is feed-forward inputted to the vibration control system of a controller 11. The vibration control system controls the drive of actuators 7A-7D and 32A-32C so as to suppress the vibration of the vibration absorbing table from the outputs of displacement sensors 10Z1 -10Z3 , 10Y1 , 10Y2 , and 10X and vibration sensors 5Z1 -5Z3 , 5Y1 , 5Y2 , and 5X, and from feed-forward input command value.  Therefore, the inclination of the vibration absorbing table caused by the vibration of the table and the movement of the center of gravity of the stage when the stage moves can be corrected.

Abstract: PURPOSE:To contrive higher operability, by automatically predicting by a printer itself the conditions of rotation of a platen by the operator, and switching a holding current so as to permit a platen knob to be rotated lightly. CONSTITUTION:A driving circuit 34 comprises an exciting circuit 41, a switching circuit 42 for sending a holding current to the circuit 41, a switching-controlling circuit 43 for supplying a control signal SS to the circuit 42, a register 44 and a timer 45. In the switching-controlling circuit 43, two kinds of conditions TA and TC for a switching-ON time T1 with the same period are preliminarily stored. In the case of TA, the holding current IA is largest, whereas in the case of TC, the holding current is sufficiently small. The holding current for a printer is so controlled that a maximum holding current is supplied to a driving motor for a predetermined period of time, e.g., for 2 to several seconds, immediately after a line feeding motor 3 is stopped or immediately after a power supply is switched ON, whereby stepout is prevented from occurring, and that the holding current is reduced to permit easy rotation of a knob 6 of a platen 1 after the predetermined period.
