| 20090114642 | MICROWAVE OVEN WITH A TRAY MOVING IN AN ORBITAL PATTERN - A microwave oven includes a heating cavity, a tray for supporting foodstuff to be heated inside the cavity, a driver including a motor and a shaft protruding into the cavity for moving the tray along a predetermined pattern, and a supporting frame with rollers interposed between the bottom of the heating cavity and the tray. The supporting frame comprises a first group of rollers adapted to be guided on the bottom of the heating cavity along a first direction, and a second group of rollers adapted to be guided on a lower surface of the tray along a second direction substantially perpendicular to the first direction, so that the overall movement of the tray is an orbital movement. | 05-07-2009 |

| 20090145621 | POWER TOOL - A power tool having a cooling system, comprises: a motor housing | 06-11-2009 |
| 20100176678 | ELECTRIC MOTOR - An electric motor includes a stator and a rotor. The stator has a housing and a single ceramic permanent magnet disposed in the housing. The magnet has a C-shaped cross section. During assembly the magnet is resiliently deformed to allow the magnet to be inserted into the housing. The inner diameter of the housing is less than the outer diameter of the magnet in its relaxed state such that once inserted in the housing the magnet is kept resiliently deformed by the housing. The magnet thus generates a radial force acting on the inner surface of the housing which results in the magnet being firmly retained in the housing. A slot is formed between opposing circumferential ends of the magnet. The slot extends from one axial end of the magnet to the other axial end. Preferably, a spacer is pressed into the slot and an interlock structure is arranged between the spacer and the housing to prevent the magnet from moving relative to the housing. | 07-15-2010 |
| 20100225198 | ELECTRIC MOTOR - An electric motor has a pair of brushes for transferring power to windings of a wound rotor by making sliding contact with a cylindrical commutator. Each brush has a body with a pair of end surfaces, and a contact surface extending between the end surfaces and configured to slidingly contact a cylindrical circumferential surface of the commutator. The extending direction of the contact surface is inclined relative to the axial direction of the commutator, and the contact surface is V-shaped when viewed in the extending direction thereof. | 09-09-2010 |
