摘要:
An apparatus including an original stage that holds an original, a substrate stage that holds a substrate, and a projection optical system that projects a pattern of the original onto the substrate, and being configured to scan and expose the substrate during a period in which the speeds of the original stage and the substrate stage change, comprises a controller configured to correct, a distortion generated in an image transferred onto the substrate due to at least one of deformation of the original stage in response to a change in speed of the original stage and deformation of the substrate stage in response to a change in speed of the substrate stage, based on a correction value determined by an acceleration of the substrate stage.

A stage apparatus has a substrate holding unit which chucks and holds a substrate, and includes a flat surface having a recess where the substrate holding unit is to be mounted. A fixing member fixes a projection support provided to the substrate holding unit onto the flat surface. The substrate holding unit is supported by the fixing member while a distal end of the projection support is in contact with the recess of the flat surface and the remaining portion of the substrate holding unit is not in contact with the flat surface.

A soft magnetic alloy strip is manufactured by a single roll method. The soft magnetic alloy strip is 0.2×d mm or less (, which “d” is a width of the strip,) in warpage in the widthwise direction of the strip, and has a continuous, long length not less than 50 m, in which a width of an air pockets occurring on a roll contact face is not more than 35 &mgr;m, a length of the air pockets is not more than 150 &mgr;m, and the centerline average roughness Ra of the roll contact face is not more than 0.5 &mgr;m.

A flat-shaped fine Fe-Ni alloy powder suitable for use as a magnetic shield coating material for cards or the like. The powder has a mean particle size of 0.1 to 30 .mu.m, a mean thickness not greater than 2 .mu.m and a coercive force not greater than 400 A/m. The flat-shaped fine powder is produced by preparing an Fe-Ni alloy powder of a composition which exhibits, in a bulk state, a saturated magnetostriction constant value falling within the range of .+-.15.times.10.sup.-6 and which contains, by weight, 70 to 83% Ni, 2 to 6% Mo, 3 to 6% Cu, 1 to 2% Mn, not more than 0.05% C and the balance Fe and incidental impurities, pulverizing the alloy powder by an attrition mill, and annealing the pulverized powder in a fluidized or moving state in a substantially non-oxidizing atmosphere.
摘要:
A method of coating a metal article comprising the steps of mixing a slurry of carbides or borides of metals selected from the group consisting of metals belonging to groups IVB and VIB of the periodic table, an organic binder and an organic solvent and then spray coating the slurry on the surface of the article, then machining the coating on the article, and heating the article under pressure so that the organic binder in the coating is heated and eliminated, and placing a metallic binder and the coated article in a furnace whereupon the metallic binder is dissolved and combined with the article.
摘要:
A method of heat-treating an amorphous material as that the amorphous material has a high magnetic permeability, is disclosed in which an amorphous material having a Curie temperature T.sub.c higher than or equal to its crystallization temperature T.sub.x is held for a short time at a temperature T satisfying relations T.gtoreq.0.95 T.sub.c and T.gtoreq.T.sub.x.
摘要:
A method of producing high-grade metal or alloy powder, improved to eliminate undesirable inclusions and to reduce the production cost. A solid electrode material made of a metal or alloy, having a composition substantially equal to the composition of aimed metal or alloy powder, is heated and molten in a vacuum chamber by application of a plasma, arc, electron beam or laser beam. The molten metal or alloy in the form of droplets fall into collision with the surface of a roll rotating at a high speed so as to be pulverized and partially solidified. The particles of the metal or alloy scattered by the roll is directed to one side of the roll and are spheroidized and solidified into fine particles before they are collected in a collecting box disposed at one side of the roll within the vacuum chamber.
摘要:
An information providing system includes a distribution device configured to distribute a display information item corresponding to an address information item, a controller configured to link the address information item to an identification information item, a transmitter in a place where an entertainment is held, the transmitter configured to transmit a transmission signal obtained by encoding the identification information item, and a receiving terminal configured to receive the transmission signal from the transmitter and decode the transmission signal into the identification information item. The display information item displays a ranking based on a number of received votes each of entrants for the entertainment has received. The distribution device is configured to update, at predetermined time intervals, the display information item that indicates the ranking based on the number of received votes and to set the address information item to correspond to a plurality of display information items.
摘要:
An exposure apparatus for illuminating an original through an illumination system and for transferring a pattern of the original onto a substrate. The apparatus includes a movable element having a blade, the blade being provided in the illumination system and blocking at least a portion of illumination light, a stator configured to relatively move the movable element, and a resilient supporting member configured to resiliently support the stator without contacting the stator.

Disclosed is an exposure apparatus for projecting, by exposure, a pattern of an original onto a substrate, the exposure apparatus including comprising a light blocking system for blocking at least a portion of exposure light, a driving system for moving the light blocking system, and a reaction force absorbing system for absorbing a drive reaction force of the driving system, wherein the driving system includes a stator, and wherein the reaction force absorbing system absorbs the reaction force by moving the stator of the driving system. With this structure, adverse influence of vibratory external disturbance to be caused by a drive reaction force as the blade of the light blocking system is driven, can be reduced significantly.
