The present invention provides a precision press device and a press load control method thereof for downsizing a vacuum chamber in press work in the vacuum chamber, shortening a time required to reach a vacuum and further performing high accuracy pressure control. To downsize a chamber, a pressure sensor is set up outside the chamberand a cylinder chamberis formed to allow a tubular plungerto slide up and down using the tubular shape of the chamber. A negative pressurein the chamberattracts the pressurized sectionand the pressurizing sectionto each other, but by injecting an equivalent pressureof a fluid into the cylinder chamber, pushing out the tubular plunger, the attractive forces are canceled out. It is possible to control the load on the substrate or the like transferred by the press stage with high accuracy.

An apparatus for manufacturing a transformer core includes a drawing which draws magnetic sheet materials in parallel from winding bodies. A cutter cuts the sheet materials at predetermined positions substantially simultaneously to form sheets each with a different length. An overlapping unit forms a block-shaped laminate by laminating the cut magnetic sheet materials in length and forms a resultant laminate by laminating the formed block-shaped laminates. An annulation unit forms an annular structure of the resultant laminate so that the longer block-shaped laminate forms the outer annular portion and the shorter block-shaped laminate forms the inner annular portion. Both ends of the magnetic sheet materials are abutted or overlapped to locate the abutted or overlapped portions at annularly different positions between adjoining layers of the magnetic sheet materials. A control unit controls the drawing unit, cutter and overlapping unit.
