The cross ring method broke off the fault of the phono- cartridge.

It merges the center point of the coil of right and left by letting the coil of right and left cross. The ability to regenerate of the LP improved drastically by making the center point the fulcrum. I was able to cancel the most of the cause of the conventional big distortion..

There were two big problems in a conventional phono- cartridge.
The conventional phono- cartridge installs a square iron core to a cantilever and winds up a coil to the iron core.
And it installs a wire in the center of the iron core.
And it is fixed through a rubber damper in York.
Therefore the movement point is located in a rubber damper in the outside of the coil.
There is the cross-shaped thing to the iron core, too.

Those methods become the electricity generating system of the magnetic induction type that they used a core of the iron for so that movement point is separated from a coil.
Therefore the piece of iron put in a magnetic field is strongly attracted to a magnet, and it is not thought that it is possible for free, correct movement.
In addition, the movement point is vague because a wire is a bending part.
The vague fulcrum cannot convey the movement of the tip to a coil precisely.
I can predict such a thing at a point in time to design the structure.

And a cross ring method was devised.

The cross ring method broke off the big fault of the conventional phono- cartridge.
The cross ring method synchronizes the center point of the coil of right and left and enables correct reproduction by assuming the center point a clear movement point.
In addition, I can change an iron core into resin because a movement point is located in a coil.
It lost the influence of the magnetic force again lightly and enabled correct movement by freedom.

It is a patent of the Miya-jima laboratory to prepare the clear fulcrum into the center point of the coil and the center point of the magnet.
I introduce the one of the patents of the MC stereo cartridge, a cross ring method here.

It was before seven years that a cross ring was completed theoretically, but many efforts were necessary to become the product.
I made the main body with wood to maintain a splendid sound. The idea gets a better result.

A figure of structure of the cartridge of the cross ring method

I explain both structure by Flash Movie.

All stereo cartridges of Miyajima-Lab are Cross Ring methods

	Takumi The sound of Takumi is clear and soft. Takumi adapts to arms various than Waza. Takumi pursued usability. And we reduced production cost of Takumi to reduce a price. The structure is a cross ring method in the same way.

	Waza It is a good sound of the balance. The sound of Waza is an obedient feeling. And I reproduce straight, splendid music. It is a heavy, clean grain of wood.

	Shilabe It is the best model of the cross ring method. The African blackwood of the main body is used for the materials of a clarinet and the oboe. It has beautiful luster with a heavy tree very firmly.

	Kansui I repeated an experiment to produce the cartridge which is better than Shilabe. I changed some parts and a manufacturing process. And, I completed cartridge "Kansui". Kansui did not exceed all of Shilabe, but I felt splendor of Kansui while I listened to many records. Balance, stillness, etc... When you listen to a magnificent orchestra, I think that you understand it.

Shibata Stylus

I use the cantilever which is bigger than a thing used generally for the cartridge of the product. The reason is from the that a cantilever bends at the time of reproduction when I use a thin cantilever. I repeated an experiment for correct reproduction. And I use the cantilever of a good result.

If you like true sounds, the cross ring method will become the best product.

			Generally a terminal of the brass is used, but uses the thing which processed copper wire.	A case and a certificate are enclosed to a product.
