Title: Electromagnetic coil
Inventor: IDE OSAMU
IPC: H01F27/28
Filed: 1988-09-29
Abstract: PURPOSE:To obtain stable, high magnetic field without suffering from the influence of the external magnetic field, by putting a magnetic substance made of soft magnetic material between respective winding layers. CONSTITUTION:Windings 12 are wound around and attached to the cervical section 10a of an iron core 10 made of soft magnetic materials in order from the inside into a multilayered structure. On this occasion, a magnetic plate 14 made of soft magnetic materials is interposed between each pair of adjoining winding layers. As each winding layer 12 of the electromagnetic coil wound around and attached to the iron core 10 adjoins a magnetic plate (magnetic plates) 14, in this way, a high magnetic field can be obtained. And, along with that, a high-inductance electromagnetic coil can be obtained. Besides, as external magnetic flux phi1 or phi2 passes through the magnetic plates 14 put between layers of the windings 12 and the flux is almost prevented from interlinking each winding 12, counterelectromotive force in the direction the same as or reverse to the current flowing in the windings is hardly generated. Accordingly, the winding current hardly varies preventing such bad influence.

Title: Positioning determination table device
Inventor: OISHI SHINJI
IPC: G01D5/20
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To determine an adequate phase exchanging position with high accuracy by simultaneously and respectively applying currents that generate driving forces which are of the same level and have opposite directions to each other to both of coils that exchange phases of a motor in the vicinity of the exchanging position, then measuring the position of a stage that stops its movement under the above condition. SOLUTION: A table 1 is driven so that a light shading plate 8 passes through an origin photo switch 9 and a counter unit 10 is initialized, than the table 1 is conveyed to a position in the vicinity of a phase exchanging position. Currents having the same level are simultaneously applied to coils 2, 3 so that generated driving forces are opposite to each other. When continuing the applying of the currents, the table 1 stops at a position wherein the generated driving forces are balanced. The above stopping position which may be an optimum exchanging position that does not generate difference in level of the driving force is measured by means of a position detector 7. This measuring operation is executed at all of the exchanging positions in a movable range of the table 1 and the results are sequentially stored in a RAM 17.  Thereby, it is possible to execute the accurate position determination without generating speed variation during the moving at a constant speed.
