    • A method of making a nitride semiconductor substrate having the steps of providing a free-standing substrate that is of a nitride semiconductor and has one of a penetrating pit and a penetrating crack that penetrate from a top surface to a back surface of the free-standing substrate, attaching a metal to the penetrating pit or the penetrating crack, the metal being adapted to be nitrided, and nitriding the metal to form a nitride that seals the penetrating pit or the penetrating crack. A nitride semiconductor substrate has a free-standing substrate that is formed of a nitride semiconductor and has one of a penetrating pit and a penetrating crack that penetrate from a top surface to a back surface of the free-standing substrate, and a metal nitride that seals the penetrating pit or the penetrating crack. The metal nitride is formed of GaN, InN and AlN.
    • 一种制造氮化物半导体衬底的方法,其具有以下步骤:提供具有氮化物半导体的自立式衬底,并且具有从自立式的顶表面到后表面穿透的穿透坑和穿透裂纹中的一种 基板,将金属附着到穿透坑或穿透裂缝,金属适于被氮化,并且氮化金属以形成密封穿透坑或穿透裂纹的氮化物。 氮化物半导体衬底具有由氮化物半导体形成的自立式衬底,并且具有从自立式衬底的顶表面到后表面穿透的穿透坑和穿透裂纹中的一种;以及金属氮化物 密封穿透坑或穿透裂缝。 金属氮化物由GaN,InN和AlN形成。

    • An image compression apparatus includes: a dividing section for dividing an image to be compressed into blocks; a discrimination section for determining whether the divided block is a first kind block, in which an outline portion of the image is not included and a difference between the maximum gradation value and the minimum gradation value of the block is equal to or greater than a reference value; and a normalization output section which divides a distribution range of gradation values depending on the discrimination result with respect to the block and outputs compressed data containing code data for showing to which area in the divided distribution rage, each pixel in each block belongs, the maximum value and the minimum value; wherein the normalization output section arranges the maximum value and the minimum value related to the block in a different order depending on whether the first kind block or not.
    • 一种图像压缩装置包括:分割部分,用于将要压缩的图像划分成块; 用于确定分割块是否是不包括图像的轮廓部分的第一类块以及块的最大灰度值和最小灰度值之间的差是否等于或大于参考的判别部分 值; 归一化输出部分,其根据关于块的鉴别结果对灰度值的分布范围进行分割,并输出包含代码数据的压缩数据,该代码数据用于表示每个块中每个像素所属的分配分布范围中的哪个区域的最大值 值和最小值; 其中归一化输出部分根据第一种块是否以不同的顺序排列与块相关的最大值和最小值。
