| 20090102402 | CONTROLLED ELECTRIC MOTOR ARRANGEMENT FOR A TENSION MECHANISM - A field-oriented control method for an electric drive comprising a plurality of electric motors, for implementing a tension mechanism, especially for load cable and/or gearing means, using measurements of a polyphase motor actual current. The measured values are transformed into a direct current component and a quadrature current component, based upon a magnetic rotor field or flux angle, in a rotor flux-based d,q coordinate system. The quadrature and direct current components from the actual current are subjected to a comparison with predetermined quadrature and direct current components of a current command value. The method has the following steps: | 04-23-2009 |
| 20110157944 | TEMPERATURE MONITORING FOR CIRCUIT BREAKERS - Method for detecting and/or monitoring the temperatures of at least two electronic power switches, in particular semi-conductor power switches that are coupled with or arranged on a common cooling body, whereby a temperature detection and/or monitoring is carried out by means of a temperature model each allocated to a switch, in which switch and operating parameters as well as temperature measurement values are processed for calculating the temperature and/or a temperature difference in the relevant switch, whereby a temperature measurement value from a temperature sensor is used as an input parameter for the temperature model, the same being centrally positioned between at least two switches and standing in a heat conducting connection with the cooling body. | 06-30-2011 |

| 20100002843 | STANDING WAVE ELECTRON LINEAR ACCELERATOR AND INSTALLATION ADJUSTING DEVICE THEREOF - The present invention discloses a standing wave linear accelerator, comprising: a microwave device configured to generate microwave; an electron beam emitting device configured to emit electron beam; an accelerating device configured to receive the microwave generated by the microwave device and form a microwave electric field, to accelerate electron beams generated from the electron beam emitting device and undertake the accelerated electron beam targeting to emit X ray beam; a synchronous device generating synchronous pulse signal; and a quick beam emitting device receiving the synchronous pulse signal generated by the synchronous device, wherein the microwave device runs and generates microwave in advance before the operation of the electron beam emitting device based on the synchronous pulse signal, and the quick beam emitting device drives the electron beam emitting device to emit electron beam after power of the microwave generated by the microwave device reaches stable state, so that the accelerating device emits X ray beam. In the accelerator, the microwave system and the electron beam emitting device do not work at the same time, and the accelerator electron beam emitting system is started only when the AFC is put into operation and runs stably. | 01-07-2010 |
| 20100219776 | MULTI-ENERGY FREQUENCY-MULTIPLYING PARTICLE ACCELERATOR AND METHOD THEREOF - A multi-energy frequency-multiplying particle accelerator and a method thereof are disclosed in order to overcome the drawbacks of the existing accelerator, such as single energy level, beam current and operating frequency limited by a single power source. The accelerator comprises a pulse power generation unit for generating N pulse signals with different power levels, N is equal to or greater than 2; N microwave power generation units for, under the control of a control signal, generating N microwaves with different energy levels based on said N pulse signals, respectively; a power mixing unit having N entrances and one exit and for inputting a corresponding microwave among said N microwaves from each of said N entrances and outputting said N microwaves from said one exit; a particle beam generation unit for generating N particle beams in synchronization with said N is microwaves; and an accelerating unit for using said N microwaves to accelerate said N particle beams, respectively. Since the multi-energy frequency-multiplying particle accelerator of the present invention can output alternately particle beams of different energy levels and thus has improved operating frequency and multiplied power, it will find a wider application prospect in the field of radiograph imaging, radioactive medicine and radiation processing industry. | 09-02-2010 |
