Title: Method of fixing magnetic ferrite core and transformer
Inventor: SEZAI YUJI
IPC: H01F1/34
Filed: 2002-04-19
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method of fixing magnetic ferrite core by which the original characteristics of a magnetic ferrite core are not deteriorated, and to provide a transformer that is manufactured by using the method and can transmit data signals with high accuracy by preventing the transmission errors by reducing the distortion of transmission waveforms and noise when the transformer makes data transmission.  <P>SOLUTION: The amount of deterioration ΔTHD of the THD characteristic of each magnetic ferrite core 1 constituting the transformer 100 due to stresses is suppressed to ≤5 dB by controlling stresses σ applied to the core 1 within the range of -0.96 MPa≤σ≤0.96 MPa. Therefore, the clamp forces of fittings 20a and 20b used for fixing the ferrite cores 1 and 1 can be set to values lower than those set in the conventional example. Alternatively, the ferrite cores 1 and 1 are fixed by using t tape instead of the fittings 20a and 20b.  <P>COPYRIGHT: (C)2004,JPO

Filed: 2002-05-01
Abstract: <P>PROBLEM TO BE SOLVED: To provide a highly accurate and efficient method for designing the balance of a rigid rotor while overcoming the drawbacks of conventional CAD- based design techniques.  <P>SOLUTION: A model of the rigid rotor is created using a three-dimensional CAD and the positions of two or more balancing planes perpendicular to its axis are designated.

If it is determined to be necessary, balancing factors of the model are calculated from the designated balancing position and the amount of residual unbalance and the shape of the model is changed using the balancing factors to calculate balancing factors of the shape that has been either added or removed. Once a state is reached where the amount of residual unbalance after the model change does not exceed the permissible amount of residual unbalance, designing is complete.  <P>COPYRIGHT: (C)2004,JPO
