3results about How to "Reduced dynamic performance" patented technology

The application relates to the technical field of semiconductors, and discloses a bidirectional semiconductor device control circuit, which comprises a bidirectional device, the bidirectional device being a single-gate bidirectional semiconductor device, and the bidirectional device having a substrate electrode; and a potential adjusting unit connected with the bidirectional device and used for controlling the potential difference between the potential of the substrate electrode and the lowest potential of the bidirectional device to be less than or equal to a first preset voltage value when the bidirectional device is in a certain working state or is switching the working state. The application can effectively improve the dynamic performance and long-term reliability of the bidirectional device.

A method for determining the output rotational speed (nA1, nA2) of the shaft (26) of a machine (27), particularly an internal combustion engine, using a filter, wherein the characteristics of the filter are determined based on the operating characteristics of the machine (27), wherein the characteristics of the filter are the filter length.

The invention relates to a rotary press, comprising: upper and lower punch guides having upper and lower press punches and a rotor of a die plate between the punch guides, the press punches cooperating with the cavities of the die plate; the filling device is used for filling the cavity with powder; the pressure device is provided with an upper pressure unit and a lower pressure unit which cooperate with the pressing punch to press the powder in the cavity into a pressed product; the scraping device is used for scraping the pressed product from the upper side of the mold disc into the first pressed product outlet; and the sorting device is used for sorting the pressed products into the second pressed product outlet. The sorting device comprises a sorting drive and a sorting element which is moved by means of the sorting drive between a sorting position, in which the sorting element is in the transport path of the pressed articles to the first pressed article outlet and guides the pressed articles to the second pressed article outlet, and a rest position, in which the sorting element is in the transport path of the pressed articles to the second pressed article outlet. A magnet driven by a stator of an electric motor converts its driving movement into a driving movement of a sorting element by means of a conversion element.
