Abstract: Disclosed is a head system including a plurality of recording heads for azimuth recording. The system includes a first recording head having a plurality of magnetic gaps having a first azimuth angle, and a second recording head having a plurality of magnetic gaps having a second azimuth angle different from the first azimuth angle. After first magnetization patterns are formed on a recording medium by the first recording head, second magnetization patterns are formed by overwriting side edge portions in the formation direction of the first magnetization patterns by the second recording head. This makes it possible to prevent the worsening of the accuracy of the magnetization pattern width due to a relative height stagger (offset) between the heads, to thereby enhance the accuracy of the magnetization pattern width, and to achieve high-density recording.

Abstract: A guide plate is provided along the outer periphery side of a rotary drum and a fixed drum on the upstream side relative to an inlet portion where a magnetic tape starts making contact with a magnetic head on the rotary drum, an airflow attendant on the rotation of the rotary drum is stripped by a wedge-shaped edge on the tip end side of the guide plate, and is released to the outer periphery side by a guide surface of the guide plate, and the airflow flowing in the axial direction from the upper end side of the rotary drum into the space between the magnetic tape and the rotary drum is restrained by an extended portion of the guide plate. By this, in a rotary head drum device for a magnetic recording/reproducing apparatus, formation of an excess of air film in the vicinity of an inlet portion of the magnetic tape can be restrained, and stable recording and reproducing can be achieved without raising the tape tension, whereby the life of the magnetic tape can be enhanced.

Abstract: A motor has a rotor mounted on a stator to rotate about a rotation axis. The rotor is driven due to the interaction of a drive coil on the stator and a permanent magnet on the rotor. A magnetic thrust bearing, having permanent magnets on the stator and rotor, applies a radial thrust force. The radially outer surface of the permanent magnet on the rotor abuts a part of the rotor, so as to resist forces on the permanent magnet at high speed rotation or due to thermal deformation. The permanent magnets on the stator and the rotor may be axially offset by an offset of not more than 1/4 the axial length of the permanent magnets, or the axial length of the longer of the permanent magnets if they have different axial lengths. This generates an axial thrust at the thrust bearing, which counteracts the attractive force between the permanent magnet and the drive coil, and also the weight of the rotor.

Abstract: A rotary body bearing apparatus has a bearing supporting member, a radial bearing member, a bearing chamber formed in the bearing supporting member for holding the radial bearing member, a rotative shaft supported rotatively by the radial bearing member, and lubricating oil filling a bearing clearance between the rotative shaft and the radial bearing member. An air bubble restraint means restrains the occurrence of air bubbles generated in the lubricating oil by the rotation of the rotative shaft. Even when the rotative shaft rotates at the high speed of rotation, by the provision of the air bubble occurrence restraint means, the occurrence of air bubbles generated in the lubricating oil can be restrained, high accuracy rotation can be maintained and a rotation number fluctuation of the rotary body can be reduced.

Abstract: A motor has a stator with a base part and a hollow projection as well as a rotor with a shaft which extends into the hollow projection. A radial bearing is mounted between the shaft and the hollow projection. There may be a further radial bearing in the base part of the stator. The radial bearing, lubricated by magnetic fluid, is sealed between the shaft and the projection by a magnetic seal at the end of the hollow projection remote from the base part. The rotor has an annular part extending around the hollow projection, which supports permanent magnets forming an armature. Those permanent magnets interact with drive coils on the stator to cause rotation of the rotor about the axis of the shaft. There is also a magnetic thrust bearing between the annular part of the rotor and the projection of the stator. This magnetic thrust bearing is axially displaced relative to the magnetic seal towards the base part of the stator, to counteract the effect of the magnetic thrust bearing on the magnetic seal.

Abstract: Disclosed is a multi-point welding method capable of certainly welding an object having a number of points to be welded for a short time. First, an approximately cylindrical base body is formed by alternately laminating a flat sheet and a corrugated sheet and then winding them in a spiral shape. In this case, there exist a number of contact points of the flat sheet to the corrugated sheet, that is, points to be welded. Next, there is provided an electrode apart from one end surface of the base body by a specified interval and facing to the end surface. After that, by intermittently applying a current across the electrode and the one end surface of the base body thereby intermittently generating electric discharges between the electrode and the one end surface of the base body, to thus fuse and weld the points to be welded of the flat sheet to the corrugated sheet.

Abstract: An apparatus for automatically inserting a plug in and to a predetermined position therein a raw pipe such as an aluminum pipe which is to be drawn for instance in a drawbench. The apparatus comprises a suppport roller which supports a plug-supporting rod at its intermediate portion near to an end of the rod, the support roller bearing a lower surface of the portion and being movable along the plug-supporting rod. The apparatus further comprises a pipe-transporting device for transporting the raw pipe, which device grips both ends of the raw pipe so as to move it towards the plug-supporting rod in a direction in alignment with an axis of said rod. A pusher protrudes forward from the pipe-transporting device so that the device starts to carry the support roller at a given instant whereby the raw pipe is prevented from directly riding the support roller and is thus protected from being scratched, and forcible pressing of the plug onto an inner surface of the raw pipe being also avoided.

Abstract: A pipe centering apparatus is of such a structure that pipes of certain kinds such as aluminum short pipes transported by a conveyor are centered with their longitudinal centers aligned with each other, before the pipes are subjected to chamfering or other processes. The pipe centering apparatus in the invention comprises a pair of right and left gears in mesh with each other and rotatably mounted on a main frame, a pair of right and left racks respectively in mesh with the right and left gears, and a pair of right and left regulators respectively secured to the right and left racks so as to come into contact with ends of the pipes, wherein the gears are rotated to cause the regulators to move towards each other and to contact the pipe ends, thereby precisely centering the pipes even where the pipes are not of strictly the same length.

Abstract: Apparatus for automatically forming pointed ends for raw metal pipes such as aluminum pipes subject to a drawing process, the pointed end of the pipes being of a reduced diameter convenient for the drawing process. A transporting device moves each raw pipe, which is in alignment with an axis of a pipe inlet of a swaging machine for producing the pointed ends, to a position below the inlet. Each pipe is raised by a lifting device to a height of the pipe inlet so as to be chucked by a gripping device which moves forward to insert a leading end of the pipe into the inlet. The lifting device and the raw pipe are kept out of contact with each other while the leading end is being processed to form the pointed end at the inserted end in the swaging machine whereby efficiency and productivity are improved for the process.
