A surface magnet type motor having a magnet at a surface of a rotor includes an anti-scattering tube formed in a cylindrical configuration longer in length than the magnet of the rotor in the axial direction, having the magnet press-fitted inside to prevent scattering of the magnet. A stress alleviation portion is provided to alleviate stress generated at an end of the magnet press-fitted into the anti-scattering tube.

An organic EL has a problem of element life. Causes of the element life include a temperature and an amount of current. As for a display using an organic EL element, light is emitted by using a current so that an amount of light emission of a screen is proportional to the amount of current passing through a device. Therefore, there are problems that an image of a large amount of light emission has a large current passing through the device causing deterioration of the element and that a high-capacity power supply is required in order to pass a maximum amount of current. As for the display using an organic EL element, the amount of light emission of the screen is proportional to the amount of current passing through the device. Therefore, the higher a maximum amount of light emission of the element is set, the larger the current becomes when all the elements of the screen emit maximum light. If the maximum amount of light emission of the element is suppressed, the entire screen becomes darker. For that reason, a drive to control the amount of light emission of the element is performed according to a display status of the screen.

A grain diameter controlling crystalline layer comprising crystalline grains of a metal selected from the group consisting essentially of Cu, Ni, Rh and Pt was formed on a substrate. Then, deposited atom layer of at least one element selected from the group consisting of oxygen and carbon was formed on the surface of the grain diameter control layer. A magnetic recording layer was deposited on the atoms deposited grain diameter controlling crystalline layer. Then a magnetic recording medium in which the magnetic crystalline grains has small grain diameter and small grain diameter distribution, and the magnetic recording medium shows increased signal to noise ratio at high recording density.

A pair of members opposed to each other via a gap are commonly used as an evanescent light probe and a writing magnetic head. When the spacing and width of the gap are smaller than the wavelength &lgr; of injected light, highly intensive evanescent light is generated from the gap position of the opposite surface. Magnetic writing is carried out by applying a recording magnetic field from the pair of members to a medium heated by the evanescent light.

A high pressure pump includes a cylinder body. The cylinder body has a cylinder and a valve recess communicated with the cylinder. A cover is attached to the cylinder body to surround the valve recess. A plunger reciprocates in the cylinder. An electromagnetic valve has a pressurizing chamber, a valve hole connected to the pressurizing chamber and a valve body. The valve body selectively opens and closes the valve hole. The electromagnetic valve is fixed to the cover. When fluid is pressurized in the pressurizing chamber, the valve hole is closed by the valve body and the plunger enters the pressurizing chamber. A seal ring is located between an outer surface of the electromagnetic valve and an inner surface of the valve recess. The seal ring seals the pressurizing chamber. This reliably seals a pressurizing chamber and improves the displacement efficiency.
