  • Patent number: 6144124
    Abstract: A thinned DC brushless motor (50) has a base plate 52 of magnetic material, a rotatable shaft (58) supported perpendicular to the base plate, an annular hub (68) coaxially fixed on the shaft, a stator (60) fixed on the base plate, and a rotor (70) coaxially fixed on the shaft through the annular hub. The rotor (70) includes an first wall portion (72) extended radially from the shaft above the stator and parallel to the base plate and a second wall portion (74) extended from a peripheral edge of the circular potion towards the base plate to enclose the stator. An annular magnet (78) is fixed on an inner surface of the second wall of the rotor with leaving a small gap from a peripheral edge of the stator. The upper wall has a bent portion (80) extended outward away from the annular magnet in the vicinity of an inner edge of the annular magnet.

  • Patent number: 4839488
    Abstract: An electric discharge machine includes a clean work fluid tank for storing a clean work fluid and a work tank connected to the clean work fluid tank for receiving and storing the work fluid. An electric discharge is designed to occur through a small space between two charged electrodes, which are a workpiece and a tool, so that at each discharge a small amount of workpiece material is removed, producing particles which are suspended in the work fluid. A settling tank is connected to the work tank that receives and stores the work fluid and a filter container containing a ceramic filter is connected between the clean work fluid tank and the settling tank, so that the work fluid which is supplied from the settling tank passes through the ceramic filter and so that work fluid which has not been filtered is sent back to the settling tank.
