    摘要： A method of making an electronic device, according to an exemplary embodiment of the invention, comprises the steps of: forming a polycrystalline substrate in a desired shape; converting the polycrystalline substrate into a single crystal substrate using a solid state crystal conversion process; and forming an electronic element on the substrate. Typically, alumina is formed in the shape of a wafer, sintered to form a densified polycrystalline alumina wafer, and heated to a temperature between the melting point of alumina and one-half the melting point of alumina to convert the densified polycrystalline alumina wafer into a sapphire wafer. A light-emitting diode or other electronic device, such as a laser diode, a high frequency microwave device, or an optoelectronic detector, can be formed on the wafer by depositing layers of semiconductor material on the wafer. The solid state crystal conversion process provides several advantages in forming electronic devices. For example, the cost of the single crystal substrate is significantly reduced since crystal growing from a melt is not required. Also, less processing is required after the crystal is formed, since the precursor polycrystalline substrate can be formed to near net shape. In addition, the polycrystalline substrate can be made in many shapes, in contrast to the shapes possible when growing a crystal from a melt.

    摘要翻译： 根据本发明的示例性实施例的制造电子设备的方法包括以下步骤：形成期望形状的多晶衬底; 使用固态晶体转换工艺将多晶衬底转换成单晶衬底; 以及在所述基板上形成电子元件。 通常，氧化铝形成为晶片形状，烧结形成致密的多晶氧化铝晶片，并加热至氧化铝的熔点和氧化铝熔点的一半之间的温度，以将致密化的多晶氧化铝晶片转化为 蓝宝石晶圆 通过在晶片上沉积半导体材料层，可以在晶片上形成诸如激光二极管，高频微波器件或光电子检测器之类的发光二极管或其它电子器件。 固态晶体转换工艺在形成电子器件方面提供了几个优点。 例如，由于不需要从熔体生长的晶体，所以单晶基板的成本显着降低。 此外，在形成晶体之后需要较少的加工，因为前体多晶基板可以形成为近净形状。 此外，与从熔体生长晶体时可能的形状相反，多晶衬底可以制成许多形状。

    摘要： An ignition system for a gas appliance comprises an ignition controller that receives a current from a power source. The ignition controller is also coupled to an ignitor and to a current actuated valve that releases a flow of gas when the current is greater than a first predetermined current value and less than a second predetermined current value. Ignition safety for the gas appliance is provided by establishing a fixed range of current through the ignitor before the gas valve is opened.

    摘要： A matching layer for ultrasound transducers has a gradient in impedance value from one surface to the other surface of the matching layer. The matching layer is composed of a plurality of sublayers made of composite materials and securely attached together and is disposed on the surface of the transducer element. The first sublayer adjacent to the transducer element has an impedance value less than or equal to that of the transducer element. The last sublayer adjacent to the target has an impedance value greater than or equal to that of the target. The impedance values of the sublayers decrease monotonically from the first to the last sublayer.
