Abstract: A transformer includes iron cores and a winding structure. The iron cores are stacked on each other at intervals, and iron core gaps are formed between the iron cores, wherein relative positions between the iron core gaps are fixed. The winding structure is disposed around the iron cores and includes a plurality of coils. A position of at least one of the iron core gaps corresponds to a position of at least one of coils.

Abstract: A magnetic component is provided. The magnetic component comprises a primary coil group, a secondary coil group, and a magnetic core. A first primary coil and a second primary coil of the primary coil group are winding around a first winding column and a second winding column of the magnetic core, respectively. The number of turns of the first primary coil is different from the number of turns of the second primary coil. A first secondary coil and a second secondary coil of the secondary coil group are winding around the first winding column and the second winding column, respectively. The number of turns of the first secondary coil is different from the turns of the second secondary coil.

Abstract: A transformer includes a magnetic core, a primary side winding and a plurality of secondary side windings. The magnetic core includes a first outer column, a second outer column, an upper cover and a lower cover. The first outer column and the second outer column are disposed between the upper cover and the lower cover. The primary side winding is disposed on the first outer column and the second outer column, and the plurality of secondary side windings are disposed on the first outer column and the second outer column. Each of the secondary windings has one end passing through a region between the first outer column and the second outer column.

Abstract: A computer-based method for controlling dragging scroll bars in a web table includes dividing the web table into a title area and a data area, and generating scroll bars for the data area. The method further includes obtaining a position and a status of a cursor on a display, and determining a moving direction of the cursor if the cursor is positioned to drag the scroll bars according to the position and the status of the cursor. Furthermore, the method includes computing a distance that the cursor moves along the moving direction on the display, and moving the title area the distance along the moving direction.

Abstract: A method for monitoring print jobs is disclosed. The method includes the steps of: capturing print jobs submitted by client computers; checking the print jobs captured according to predetermined printing tactics that specifies requirements of a valid print job, in order to determine valid print jobs; recording information of all the captured print jobs, and saving the information in the database server; and instructing the printers to execute the valid print jobs. A related system is also disclosed.
