  • Patent number: 9802402
    Abstract: A method of manufacturing a heating device includes preparing a substrate having a curved surface; and forming a heating body on the substrate, the heating body generating heat with a supply of electric current. The forming of the heating body includes pressing a screen toward the substrate with an aid of a pressing member while rotating the substrate and moving the screen, and transferring application liquid that is to form the heating body to the substrate through the screen. In the forming of the heating body, the pressing member is in contact with the screen at a position on an upstream side with respect to a transfer position in a direction of movement of the screen.

  • Publication number: 20070256774
    Abstract: A method of and system for manufacturing a microstructure having high form accuracy and a manufacturing system is disclosed. On a rough motion stage having a predetermined positioning accuracy and a large stroke length, a fine motion stage having a small stroke length and a higher positioning accuracy is placed. First, the rough motion stage is moved to a desired position. By use of a mirror placed on a laser length measuring machine and the fine motion stage, the current position of a thin film member on the fine motion stage is precisely measured. This measurement value is feed-backed to a stage control device, and a difference between the current position and a target position is calculated by an error correcting unit. Thus, an error correcting instruction value is generated to move the fine motion stage to the target position. Thus, an error of the rough motion stage is corrected.

  • Publication number: 20070065595
    Abstract: A substrate on which a plurality of thin films having a plurality of cross-sections corresponding to the cross-section of a micro-structure are formed is placed on a substrate holder. The substrate holder is elevated to bond a thin film formed on the substrate to the surface of a stage, and by lowering the substrate holder, the thin film is separated from the substrate and transferred to the stage side. The transfer process is repeated to laminate a plurality of thin films on the stage and to form the micro-structure. Accordingly, there are provided a micro-structure having high dimensional precision, especially high resolution in the lamination direction, which can be manufactured from a metal or an insulator such as ceramics and can be manufactured in the combined form of structural elements together, and a manufacturing method and an apparatus thereof.
