    摘要： In a core material according to the present invention, a predetermined number of core pieces, each having a tooth portion and a yoke portion, are connected to each other via connecting portions. Each of the connecting portions includes: a V-shaped notch portion; a through hole that is formed at a tapered portion of the notch portion with a diameter elongated in a connection direction; and a thin portion that is formed outside of the through hole and connects the core pieces to each other. The width of the thin portion is more increased apart from the axis of symmetry of two sides constituting the V shape of the notch portion, and further, an intersection between extension lines of the two sides constituting the V shape lies within 0.3 W from the inner side of the thin portion in a notch direction and within the thin portion when W designates the width of the thin portion along the axis of symmetry.

    摘要： A failure analysis system (900) for printed circuit board (600) includes testing equipment (100) and a monitor (200). The testing equipment includes a base (120), a fixing body (180), a supporting arm (140) and a micrometer (160). The fixing body and the supporting arm are both firmly fixed on the base. The printed circuit board is fastened to the fixing body. The micrometer is slidingly attached to the supporting arm. The micrometer has a pin (1612) at one end thereof for resisting one end of the printed circuit board. The monitor electronically connects with the printed board for receiving signals from the printed circuit board. When the pin of the micrometer reaches a certain position, the signal transmitted to the monitor is broken.

    摘要： A motor includes a stator which includes a stator core having an annular stator yoke, a plurality of outer teeth projecting outward from the stator yoke and a plurality of inner teeth projecting inward from the stator yoke, and a plurality of windings wound on the stator core. The motor also includes an outer rotor confronting the outer teeth with an air gap therebetween and an inner rotor confronting the inner teeth with an air gap therebetween. This motor thus has twin-rotor. The stator core includes outer slots between each one of the outer teeth as well as inner slots between each one of the inner teeth, and the windings are wound on the stator yoke between the outer slot and the inner slot. A cross sectional cut of the stator reveals that a sectional area of the outer slot is equal to that of the inner slot.

    摘要： The method and system for data interworking between networks in accordance with the embodiments of the present invention forward a data packet from a wireless network to an IWF module via an ATM interface. The IWF module extracts an IWF user-plane payload from the data packet and modulates the IWF user-plane payload to form a code stream and sends the code stream to a fixed communication network. In another method and system for data interworking between networks in accordance with the embodiments of the present invention, the IWF module processes including demodulating the data from the inter-network communication conversion device, extracts the IWF user-plane payload from the demodulated data, converts the extracted IWF user-plane payload to a data packet supporting the ATM protocol and sends the converted data packet to the wireless network via the ATM interface. As above, the embodiments of the present invention can decrease communication delay, thereby improving user's satisfaction.
