    • A substrate for forming a semiconducting layer is provided to grow the semiconducting layer on a major surface thereof, wherein the substrate comprises a single crystal of a chemical formula of XB2 where X contains one of Ti and Zr and the major surface may preferably be substantially parallel to plane (0001) of the single crystal because the plane (0001) of the boride substrate is highly coherent to the lattices of GaN and AlN layers grown eptaxially on the substrate. The single crystal of the substrate may be a solid solution containing impurities of not more than 5%, wherein at least one of the impurities is one selected from Cr, Hf, V, Ta and Nb. Further, a semiconductor device includes the substrate of a single crystal of a chemical formula of XB2 and at least one semiconducting layer which is grown epitaxially on the substrate, the semiconducting layer including a nitride semiconductor of a chemical formula of ZN where Z is one of gallium, aluminum and indium and boron. The device can be used for a light emission diode in which one or more connection electrodes are attached on the substrate.
    • 提供用于形成半导体层的衬底以在其主表面上生长半导体层,其中衬底包括XB2化学式的单晶,其中X包含Ti和Zr之一,并且主表面可以优选地基本上平行 (0001),因为硼化物衬底的平面(0001)与在衬底上正面生长的GaN和AlN层的晶格高度一致。 衬底的单晶可以是含有不超过5%的杂质的固溶体,其中至少一种杂质是选自Cr,Hf,V,Ta和Nb中的一种。 此外,半导体器件包括化学式为XB2的单晶的衬底和在衬底上外延生长的至少一个半导体层,所述半导体层包括化学式ZN的氮化物半导体,其中Z是 镓,铝和铟和硼。 该器件可用于其中一个或多个连接电极附着在衬底上的发光二极管。

    • An information processing apparatus for executing information processing on a sheet material using a head member arranged for information processing area comprises a head mounting member for mounting a head member thereon, this head mounting member having a position for attaching and detaching the head member to and from the head mounting member, and a mounting position to mount the head member on the head mounting member by positioning the head member with respect to the head mounting member; a pressing member movably arranged on the head mounting member, this pressing member abutting upon the head member mounted on the head mounting member to cause the head member to shift from the attaching and detaching position to the mounting position by the application of pressure given to the head member; and a contact area for the pressing member and head member to abut upon each other, this contact area being arranged to reduce slide resistance to occur in the direction different from the direction in which the head member shifts from the attaching and detaching position to the mounting position. With this structure, the slide resistance to be exerted between these members, which may produce adverse effect on positioning the head member, is made extremely small in order to reliably position the head member exactly.
    • 一种信息处理装置,用于使用布置用于信息处理区域的头部件对片材进行信息处理,包括用于在其上安装头部构件的头部安装构件,该头部安装构件具有用于将头部构件附接和/ 头安装构件,以及通过将头构件相对于头安装构件定位而将头构件安装在头安装构件上的安装位置; 按压构件,可移动地布置在头部安装构件上,该按压构件邻接在安装在头部安装构件上的头部构件上,以使头部构件通过施加施加压力而从安装和拆卸位置移动到安装位置 总会员 以及用于按压构件和头构件彼此抵靠的接触区域,该接触区域布置成减小在与头部构件从安装和拆卸位置偏移到安装件的方向不同的方向上发生的滑动阻力 位置。 利用这种结构,为了可靠地精确地定位头部构件,施加在这些构件之间施加的可能对头部构件的定位产生不利影响的滑动阻力非常小。
