Patent EP-0520685-A1 (EP)
Inventor: DUNLOP ALFRED EARL
IPC: H03H11/24
Filed: 1992-06-18
Abstract: Effective control of impedance values in integrated circuit applications is achieved with an integrated circuit transistor (20) whose size is digitally controlled. The digitally controlled size is achieved, for example, with a parallel interconnection of MOS transistors (24). In one application, the digitally controlled transistor serves as a controlled impedance connected to an output terminal of an integrated circuit. In that application, a number of transistors are enabled with control signals, (21), and the collection of enabled transistors is responsive to the input signal (26) that normally is applied to a conventional transistor. In another application, where the digitally controlled transistor serves as a controlled impedance at the input of a circuit, only the control signals that enable transistors and thereby determine the effective developed impedance are employed. In still another application, the digital control of the transistor's size is employed to control the speed or power consumption of the effective transistor. Such control is exercised to erase the manufacturing variability of the integrated circuit. Alternatively, such control is exercised as part of a feedback control of the operational characteristics of the entire circuit. In the feedback control application, the digital signals that control the transistor's size are obtained from an assessment of the circuit's operation. In the manufacturing variability control application, the digital signals that control the transistor's size are obtained from a measure of the integrated circuit's parameters relative to a reference element.

Abstract: In order to weld, without filler metal, two metal workpieces having substantially different melting points, it is proposed to preheat the welding area of each of the workpieces to a temperature close to, but remaining slightly less than this melting point. For this purpose, a high-frequency coil (22) is placed around the welding area of the workpiece (Pa) which has the lower melting point and the welding area of the second workpiece (Pb) is placed at a controlled distance away. When the preheating has been completed, the two workpieces are brought into contact and the welding areas are fused together by resistance heating (Joule effect). Finally, impurities and compounds defined to be liable to embrittle the weld, which exist in the molten area, are removed by applying a mechanical shock between the workpieces. <IMAGE>

Des bobinages (7) associés aux pôles du stator sont connectés afin d'être excités par une source polyphasée telle que deux phases (A, B) de la source soient produites simultanément. La production simultanée de deux phases a pour résultat la magnétisation de pôles adjacents du stator par paires avec une polarité opposée, ce qui forme un circuit magnétique (36) dont l'itinéraire ne comprend que la partie de la culasse reliant les deux pôles de stator adjacents d'une paire. Le moteur selon cette invention offre un couple considérablement augmenté par rapport à un moteur à réluctance à commutation conventionnel de la même taille, tout en ayant également une meilleure efficacité.
