  • Publication number: 20240105420
    Abstract: A data generation apparatus of one embodiment includes a processing unit, an evaluation unit, and a conversion unit. The processing unit designs, through optical proximity correction based on a target pattern formed on a substrate using the photomask, a mask pattern corresponding to the target pattern and including a plurality of rectangular regions. The evaluation unit evaluates the mask pattern using a cost function having, as a parameter, a jog length indicating a length of each of the rectangular regions included in the mask pattern in a first direction. The conversion unit converts mask pattern data indicating the mask pattern with an evaluation that meets a predetermined condition to drawing data corresponding to a variable shaped beam drawing process.

  • Publication number: 20220140762
    Abstract: There is provided a transport system comprising: a stator having a first magnetic force unit; a mover having a second magnetic force unit; and a control unit. The control unit controls a magnetic force acting between the first magnetic force unit and the second magnetic force unit to transport the mover in a first direction. The stator has a first regulating member row including a plurality of first regulating members and a second regulating member row including a plurality of second regulating members, the mover, in a second direction intersecting the first direction, being disposed between the first regulating member row and the second regulating member row. The control unit performs a first process of applying a rotational force to the mover such that one of the first regulating members in the first regulating member row serves as a fulcrum when the mover contacts the first regulating member row.

  • Patent number: 11204446
    Abstract: An antireflection film is arranged on a surface of a substrate layer. The antireflection film includes a multilayer film arranged on the surface of the substrate layer and a protective film arranged outside the multilayer film. The multilayer film is formed by stacking two or three low-reflection layers. Two protective films are successively arranged outside the multilayer film of the antireflection film. An optical component includes the antireflection film arranged on both sides or one side of an optical filter of the optical component. The high-performance antireflection film can be obtained with respect to a broadband wavelength ranging from 400 nm to 800 nm, and the antireflection film can reduce the occurrence of ghosts or flare when used in an optical system.

  • Patent number: 9067303
    Abstract: A chamber having a water jet generation apparatus and a mesh installed inside is pushed against a surface of a peening object. A rotary vane of the water jet generation apparatus, disposed in a region in the chamber between the mesh and the chamber, is rotated to generate a water jet flowing toward the peening object in one region in the chamber, the one region is a region closer to the peening object than the mesh. A plurality of shots 4 put in the region 30A moves toward the peening object along with the water jet and collides with the surface of the peening object. After the collision, the shots move toward the mesh along with the water jet. Compression residual stress is given to the surface of the peening object with which the shots have collided. Thus, spreading of contaminants peeled off from a peening object can be prevented.

  • Publication number: 20150142182
    Abstract: An active anti-vibration apparatus is provided that supports a wide range of vibration accelerations using only one type of anti-vibration mechanism. Upon occurrence of an excessive acceleration, the active anti-vibration apparatus performs switching such that an acceleration detection gain 14b of an acceleration amplifier 14 is multiplied by a prescribed magnification, the cutoff frequency of a high-pass filter 11a of a vibration control unit 11 is increased, and an acceleration control gain 11b of the vibration control unit 11 is multiplied by the reciprocal of the prescribed magnification.

  • Publication number: 20150013413
    Abstract: A water jet peening apparatus (WJP apparatus) includes a seating member, rotating portion set to it, and first and second injection nozzles. A hoisting apparatus is attached to the rotating portion, and the first and second injection nozzles are attached to a nozzle arm. The WJP apparatus is gone down in a reactor vessel (RV) by crane operation, and the seating member is seated on a bottom mounted instrumentation nozzle welded to a bottom head of the RV. By the hoisting apparatus, the nozzle arm is gone down and the first and second injection nozzles are gone down. The first injection nozzle is inserted into the bottom mounted instrumentation nozzle and the second injection nozzle is set outside the bottom mounted instrumentation nozzle. High-pressure water is jetted from the first and second injection nozzles, and WJP is implemented for both of the inner and outer surfaces of the welding area of the bottom mounted instrumentation nozzle.

  • Publication number: 20140233689
    Abstract: In a water jet peening apparatus, a high-pressure under-water pump is installed on an upper end of a casing and an injection nozzle drive mechanism equipped with an injection nozzle is attached to the casing. A high-pressure hose whose one end is connected to the high-pressure under-water pump is disposed in the casing and the other end of the high-pressure hose is connected to the injection nozzle. The casing is seated at an upper end of a control rod drive mechanism housing and the high-pressure under-water pump is driven. The high-pressure water pressurized by the high-pressure under-water pump is supplied to the injection nozzle through the high-pressure hose in the casing and is jetted toward the weld portion between the control rod drive mechanism housing and a stub tube. The time required for a water jet peening operation can be shortened.
