化または小型化したレータリートランスを提供する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tattoo lance. A tally transformer is used as a means to transmit electrical signals from a rotating head in a video recorder, a sensor for a rotating body, etc. to a path in a stationary part.
Between these concepts, Figure 1 and Figure 2 show a rotary transformer that transmits signals from the head of a two-head video recorder, with Figure 1 being a disk type and Figure 2 being a coaxial type. The coil 51 connected to the magnetic head H1%H1 acts magnetically with the coil 4' of the stator 21 through the surface of the rotor 11 rotated by the shaft 5'.
, 4", the larger the interaction, the better, so
The coils 5' and 4' are magnetically exposed on the opposing surface of the stator 21, and the opposite surface of the coil is supported by a highly rigid magnetic material such as ferrite. However, the fill s1.41 l
In order to increase the number of linkages of the magnetic flux of the 7-elite, it is necessary to make the thickness of the 7-elite sufficiently large. J! Specifically, between the coil and the rigid body, a highly permeable high-crystalline magnetic alloy layer with extremely high magnetic permeability or a high magnetic permeability ferrite layer such as Ni-Zn ferrite with extremely high magnetic permeability is used. By interposing sintered 7-elite with good mechanical properties or in some cases mu-1,0. %Tie
To provide a thinner or smaller scale transformer using a non-magnetic material such as , etc. without deteriorating the characteristics.

る。In the printing method, the part that is to become a rigid substrate is a paste such as ferrite powder, alumina powder, or titania powder that exhibits good mechanical properties after sintering, and the part that is to become a high magnetic permeability thin film is a permalloy surface* or Ni-M*-. Z m 7 E-fit powder paste, coil conductor is metal powder paste F, and the part that should become the insulating layer is glass or N1-Mu-Z+a
The insulator is made by vapor deposition of titania, glass, or alumina, and the conductor is also made by vapor deposition without firing. In the case of the thin screen method, the coil conductor may be coated with polyurethane or the like, and in this case, the coil conductor can be bonded to the permalloy surface with an adhesive.

端’l s Sl 、’m s s。In the following, an example of a printing method will be described as shown in Section HH, where a disk-shaped paste of magnetic 7) powder that exhibits mechanical properties is printed on a suitable substrate (not shown) to form the substrate 1. The thickness is determined so as to provide sufficient rigidity; therefore, printing of this part may be repeated several times. On top of this, a paste of Nl-Mu-Lm 7-elite powder or permalloy powder is printed as shown in 11M4- to form a high magnetic permeability thin layer 2. Further, a thin powder paste of glass, alumina or titania is printed on this for insulation, and on top of that, two spiral conductors 13 and 14T are printed as shown in No. 5 wJ (must be a 2-head method). (if one conductor is enough). Furthermore, 84 g of glass, alumina, or titania paste is thinly printed on top of the insulating layer 5 to protect the conductor 3.4. At this time, conductor i, 417) terminal 'l s Sl ,' m s s.

As shown in Figure t1My, conductor terminals s1, r, ss, sFl are drawn out to the outer periphery of the disk by forming a drawer@7 with conductor paste, and a connecting terminal portion is formed on the surface of the old board scrap. Finally, as shown in FIG. 8, through holes 8 are punched to form a laminated structure as shown in FIG. 9.

Prepare two parts (but make necessary changes) and configure one as a data center and the other as a stator. The first
Let's use a rotary i-lance as shown in the figure.

。Because of the above structure, a high magnetic permeability layer such as permalloy is located directly behind the coil conductor and enhances the interaction (magnetic flux linkage) between the coils, so the overall shape is small or thin. The advantage is that the rotor and stator can be configured as follows.
