    • A gas turbine combustor comprises a cylindrical outer casing having one end closed by a header plate. A combustor liner provided with an inner combustion chamber which is divided into a first-stage combustion region on a side of the header plate and a second-stage combustion region formed on a downstream side of the first-stage combustion region. A first-stage fuel supply unit mounted to the header plate for injecting a first-stage fuel to the first-stage combustion region and a second-stage fuel supply unit mounted to the header plate for injecting a second-stage fuel previously mixed in a lean fuel state. The first-stage fuel supply unit includes a first-stage fuel nozzle assembly, which supplies the first-stage fuel, formed by combining a diffusion combustion nozzle and a pre-mixture combustion nozzle. The pre-mixture combustion nozzle has, at an intermediate portion thereof, a pre-mixing portion for preliminarily mixing the first-stage fuel with an air, and the pre-mixing portion having a diameter in a downstream portion thereof smaller than that of an upstream portion thereof so as to form a pre-mixed flow into a contraction flow. The pre-mixing fuel nozzle of the first stage fuel nozzle assembly is disposed so as to surround the diffusion combustion nozzle disposed in a central portion thereof.

    • There is disclosed a magnetooptical recording medium provided with at least a recording layer and a reading layer both composed of magnetic layers showing vertical magnetic anisotropy, in which the recording layer has a higher coercive force and a lower Curie temperature than those of the reading layer at room temperature, wherein the thickness of the recording layer is 1/10 to 1/1000 of the diameter of the magnetic domain formed in the recording layer by information recording, and the reading layer is so positioned with respect to the recording layer that a floating magnetic field emanating from the magnetic domain in the recording layer shows positive and negative peaks in the reading layer in the vicinity of the boundary of the magnetic domain. Secure regeneration of information with a high S/N ratio is possible from such recording medium by irradiating the reading layer with light while applying a magnetic field of which magnitude is larger than the coercive force of the reading layer, smaller than that of the recording layer and smaller than the peak value of the floating magnetic field emanating from the recording layer, and detecting the regenerating light modulated in polarization according to the direction of magnetization of the reading layer.
    • 公开了一种具有至少记录层和读取层的磁光记录介质,该层由显示垂直磁各向异性的磁性层组成,其中记录层具有较高的矫顽力和比读取层低的居里温度 室温,其中记录层的厚度是通过信息记录形成在记录层中的磁畴的直径的1/10至1/1000,并且读取层相对于记录层被定位成浮动 在记录层中从磁畴发出的磁场在磁畴边界附近的读取层中显示正和负峰。 可以从这种记录介质通过用光照射读取层来施加具有高S / N比的信息的安全再生,同时施加大于读取层的矫顽力的磁场的磁场小于记录层的磁场 并且小于从记录层发出的浮动磁场的峰值,并且根据读取层的磁化方向检测以极化方式调制的再生光。
