A method and apparatus for easily generating ozone with a high concentration in the air without requiring a high voltage power supply or a vacuum apparatus, wherein an ozone gas with a high concentration is generated in the atmosphere around a hemimorphic crystal of which the direction of polarization is uniform by placing the crystal in the air and repeatedly heating and cooling the crystal, are provided.

Method for generating ozone using hemimorphic crystal and apparatus for the same

An X-ray generator uses a high electrical field generated when a hemimorphic crystal is heated or cooled. The crystal may be lithium niobate polarized in one direction. An X-ray target is placed inside a housing inside which a vacuum is maintained. A tungsten line containing thorium is placed between the crystal and the target. When the crystal is heated or cooled by a Pelletier element, an intense electrical field is generated around the crystal. Thermoelectrons released from the tungsten line accelerate as a result of the electrical field and collide with the X-ray target. The X-rays released at this time radiate through a beryllium window exteriorly of the housing. Intense X-rays are generated without using large scale equipment, such as a high voltage power source.

X-ray generator using hemimorphic crystal

An x-ray generator comprising a vesselin which a low pressure gas atmosphere is maintained, hemimorphic crystal supporting meansandprovided in the vessel, at least a pair of hemimorphic crystalsandarranged oppositely at an interval and supported by the hemimorphic crystal supporting means in the vessel, and meanstoandfor elevating and lowering the temperature of the hemimorphic crystals. X-rays are radiated from the vessel as the temperature of the hemimorphic crystals is elevated or lowered.

A window stay is provided for a casement type window so that its window sash is shifted outwardly from the window frame as it is being opened. The window stay comprises a first arm, a second arm, and a third arm associated with a driving rod. The first arm has its respective ends pivotally attached to the window sash and the window frame and swings the window sash in relation to the window frame as the driving rod is operated. The second arm has its ends respectively pivotally attached to the window sash and the driving rod and swings the window sash in relation to the first arm as the driving rod is operated. The third arm has its ends respectively pivotally attached to the first arm and the driving rod and swings the first arm in relation to the window frame in accordance with the movement of the driving rod.
