Abstract: Disclosed is a method of manufacturing plasma display panels for carrying out aging with high productivity. In an aging process for applying a predetermined voltage and driving plasma display panels 21 for display operation, each plasma display panel is set into an aging unit provided with cooling means, and the aging is carried out on the plasma display panel while cooling the plasma display panel by the cooling means provided in the aging unit. This method can thus reduce temperature rise of the panel and prevent the panel from being cracked during the aging process.

Abstract: A horizontal machine tool has a spindle head which supports a horizontal tool spindle. The spindle head is guided on a top surface portion of a base such that the spindle head is movable in two horizontal directions X and Z. A workpiece support for supporting a workpiece on its upper end is guided on the vertical front face portion of the base for movement in a vertical direction Y. When the spindle head is located at a machining position at the center in the X direction, a pair of guide portions of each of a front/back guide mechanism for the spindle head and a vertical guide mechanism for the workpiece support body take symmetrical positions with respect to a vertical plane including the axis of the tool spindle. A first index member and a second index member for supporting the workpiece are provided on the workpiece support body. Therefore, all surfaces of the workpiece excepting an attachment surface can be machined while being directed to a tool on the tool spindle.

Abstract: A clamping device which holds a workpiece at a predetermined position during a machining operation of the workpiece comprises a clamper for clamping a workpiece, a feed device for moving the clamper in the axial direction, a load sensor which is fixed to the clamper and detects a clamping force acting on the workpiece, and a memory in which a target clamping force corresponding to the shape of the workpiece and a method of machining operation is stored. The control device compares the clamping force detected by the load sensor with the target clamping force stored in the memory and controls the clamper in response to the deviation between the detected clamping force and the target clamping force. The clamping device also has a position detecting means for detecting the axial position of the clamper.

Abstract: An apparatus for applying a magnetic field has a permanent magnet, pivotally supported, which has an approximate cylindrical shape, respective semicircles of a circular section thereof being magnetized as N and S poles, and a driving coil, located in the vicinity of the permanent magnet so that the permanent magnet can partially penetrate inside the loops of the driving coil, the rotation and the positioning of the permanent magnet being controlled by the strength and/or directions of current flow in the driving coil. The apparatus is used for a magneto-optical disk storage. Since the driving coil is close to the permanent magnet, the pivoting of the permanent magnet can be controlled with a fast response. In addition, the apparatus can be made relatively small.
