Abstract: Disclosed is a linear motor which includes a stator and a mover. The stator extends along a first axis. The mover is arranged so as to extend along the first axis and radially face the stator. The mover has a pole interval along the first axis different from that of the stator. At least one of the stator and the mover has a plurality of permanent magnets arranged in alignment with each other along the first axis, and a plurality of yoke parts arranged in alignment with each other along the first axis. The permanent magnets are provided, for each pole, in a continuous range along the first axis. The permanent magnets are polar anisotropic magnets that are magnetized from both end portions along the first axis to a radial end portion at a center along the first axis, or magnetized in the reverse directions to these.

Abstract: A wear amount estimation device estimates the amount of wear on mover wheels of a conveying device having a mover movable by a wheel-type guide mechanism, the mover being driven and controlled by a linear motor. The wear amount estimation device includes: a data acquisition unit that acquires, as estimation data, information on a control current flowing through the linear motor in order to drive and control the mover and information on a controlled position or speed of the driven mover; a storage unit that stores a wear amount estimation model for estimating the amount of wear; and a calculation unit that estimates the amount of wear by inputting the estimation data to the wear amount estimation model.

Abstract: A protective-film forming method for a semiconductor substrate suppresses deterioration in the number of LPDs and adhesion of impurities such as particles by forming a new protective-film of a surfactant solution when the semiconductor substrate is detached from a polishing head. The method includes a first protective-film forming process for forming a protective-film by hydrophilizing the front surface of the polished substrate with a surfactant solution and, after the first protective-film forming process, a second protective-film forming process for forming protective-films on the front and back surface of the substrate by detaching the substrate from the polishing head in a state where at least the front surface of the polished semiconductor substrate is in contact with the liquid surface of the protective-film forming treatment liquid comprising a surfactant solution, then by immersing the polished substrate in a protective-film forming treatment liquid.

Abstract: An opening-closing control device drives an opening-closing member with use of a drive device and controls the opening-closing member to open or close an opening portion. The opening-closing control device includes a load detector and a drive-force stopping device. The load detector detects an increase of load on the opening-closing member due to pressing of the opening-closing member against an elastic member that is disposed on an end of the opening portion and is opposed to the opening-closing member in a moving direction of the opening-closing member. The drive-force stopping device stops a drive force supplied to the drive device at a timing just before the opening-closing member reaches a mechanically limit position in a closing direction of the opening-closing member when the increase of load is larger than a predetermined threshold.
