Abstract: Provided is a method for manufacturing a high-quality porous film. Here, while the porous film is being manufactured through forming micropores by stretching, a raw film is prevented from slipping on the surfaces of the respective rolls as much as possible even though the raw film includes oil or liquid paraffin as a solvent. The method is for manufacturing a porous film through forming micropores by successive biaxial stretching. A tensile force applied to the raw film F transferring from the longitudinal stretching machine (10) to the transverse stretching machine (50) is set not less than a stretching force necessary for the longitudinal stretching, and thus the raw film is prevented from slipping on a contact surface between the raw film and each roll of the longitudinal stretching machine (10).

Abstract: An inverter power generator includes a current controller 14a setting a current limit ratio according to a rotation speed of a synchronous motor 13 and controls a converter current according to the current limit ratio. The current controller sets the current limit ratio to 70% if the synchronous motor is at a rotational speed equal to an idle speed of an engine 11. Until the rotational speed of the synchronous motor reaches a rated speed, the output current limiter linearly increases the current limit ratio up to 100%. With this, the rotational speed of the engine becomes reasonably increasable even if a sudden load increase occurs when the engine is operating at low speed.

Abstract: An inverter includes a voltage command generator generating a voltage command value according to an externally specified voltage value, a PWM signal generator generating a PWM signal according to the voltage command value and frequency command value, and a switching unit generating a three-phase AC power according to the PWM signal. The voltage command generator decreases the voltage command value if the output current increases, to prevent the rotation speed of a prime move from suddenly changing. If the output current exceeds a preset upper current threshold, the voltage command value is clamped at a preset minimum output voltage, thereby securing the minimum output voltage for an increase in the output current.

Abstract: A machining method of a press die having a pierce cutter and a secondary relief-clearance area recessed inward relative to a profile of the pierce cutter. A plunge cutting tool has an edge portion protruding from an outer circumference of a tool body and can carve while rotating and moving in an axial direction of the tool body. While rotating the plunge cutting tool with an axis of the tool body being approximately parallel to a surface of the pierce cutter, the plunge cutting tool is relatively moved along the profile of the pierce cutter. The plunge cutting tool is also relatively moved in the axial direction of the tool body along the shape of the pierce cutter and the secondary relief-clearance area in a piercing direction each time the plunge cutting tool is relatively moved by a predetermined pitch.

Abstract: There is provided a roll machining apparatus for machining the surface of a roll, which can accurately support a roll by hydrostatic bearings while absorbing thermal expansion of the roll in the length direction, thus enhancing the machining precision. The roll machining apparatus can include a first hydrostatic radial bearing for receiving the radial load of a first spindle and rotatably supporting the first spindle, a hydrostatic thrust bearing for receiving the thrust load of the first spindle and limiting axial movement of the first spindle, a second hydrostatic radial bearing for receiving the radial load of a second spindle and rotatably supporting the second spindle, and a floating thrust having a thrust bearing for receiving the thrust load of the second spindle. The floating thrust selectively limits and permits axial movement of the thrust bearing.

Abstract: A screw is moved along an axis by a screw advancement-retraction mechanism. A screw rotation mechanism is supported for movement along the axis by a pair of supporting members, each includes a rail for use as a guide member. The supporting members are arranged individually along tie-bars for use as lateral members and extend parallel to the tie-bars. One longitudinal end portion of each supporting member is secured to a frame of an injection unit by a fixing portion including a fixing member. The other end portion of the supporting member is supported on each tie-bar by a movable portion including a sliding member. The sliding member is movable along an axis of the tie-bar. With this arrangement, deformation, if any, of the tie-bar is prevented from affecting the rail, so that the screw rotation mechanism and the screw can move steadily.
