摘要:
A method for manufacturing an optical element includes heating an optical material up to a first temperature that is higher than a transition point, pressurizing the optical material using a first mold and a second mold that are situated opposite to each other across the optical material, first cooling the optical material down to a second temperature that is higher than a strain point and lower than the first temperature while pressurizing the optical material with a predetermined load using the first mold and the second mold, releasing the predetermined load at a set speed that is higher than or equal to a speed obtained in advance, at which an elastic deformation occurs preferentially over a viscous deformation in the optical material upon releasing a load, and second cooling the optical material down to a third temperature that is lower than the second temperature.

An imprint apparatus includes a mold holder that holds a mold, a substrate holder that holds a substrate by suction, a driving device that brings the mold into contact with an imprint material on the substrate by relatively bringing the mold holder and the substrate holder close to each other, and a controller. The controller controls the driving device so as to bring the mold into contact with the imprint material in a state in which the substrate is deformed into a convex shape with respect to the mold by controlling pressures inside the plurality of suction regions based on surface shape data of the substrate held by the substrate holder.
摘要:
A system for making a nonwoven nonwoven spun-bond or melt-blown fabric has a spinneret for spinning fibers or filaments, a cooler downstream of the spinneret for cooling the spun fibers or filaments, a stretcher downstream of the cooler for stretching the cooled fibers or filaments, and a conveyor downstream of the stretcher. The stretched and cooled fibers or filaments are deposited as a nonwoven web on the conveyor. Sensors measure input parameters at the spinneret, at the cooler, at the stretcher, and/or at at least one diffuser or at the conveyor. An evaluating unit for determining an output parameter from the measured input parameter with respect to a predetermined reference parameter.

A driving apparatus is disclosed which has a movable part, a measuring device measuring a position of the movable part, two actuators respectively generating two thrusts which have a common axis of action thereof with respect to the movable part, and a controller that controls the position by the two actuators based on output of the measuring device. The controller obtains information of at least one of a thrust constant of one of the two actuators, a thrust constant of the other of the actuators, and rigidity of a member which supports the movable part with respect to the axis of action, based on a relationship between disturbance force estimated from thrust commands for the two actuators and an output of the measuring device in a case where the one actuator generates a thrust and the other actuator controls the position, and a thrust command for the one actuator.

A molding apparatus (1) includes: a servomotor (11) for pressing a resin component (W) by moving an upper mold (MU) in a direction in which the upper mold (MU) is made close to a lower mold (ML); servomotors (12a and 13a) each of which retains X-coordinate and Y-coordinate positions of the lower mold (ML); and a position detection section (41) which determines whether or not the resin component which is sandwiched between the upper mold and the lower mold has been cured, the servomotors each terminating the retention of the lower mold when the resin component has been cured. This makes it possible to obtain a molded product while preventing positional displacement caused by a decrease in volume of a resin which is being cured.
