    • To realize an ohmic electrode having practically satisfactory characteristics relative to GaAs semiconductors, first formed on an n+-type GaAs substrate are a Ni thin film with a thickness between 8 nm and 30 nm, an In thin film with a thickness between 2 nm and 6 nm and a Ge thin film with a thickness between 10 nm and 50 nm, sequentially. After that, the n+-type GaAs substrate having formed the Ni thin film, In thin film and Ge thin film is annealed at a temperature between 300 to 600° C. for a few seconds to minutes. As a result, the ohmic electrode has a multi-layered structure including an n++-type re-grown GaAs layer re-grown from the n+-type GaAs substrate, InGaAs layer and NiGe thin film. Alternatively, before the annealing, a thin film of a refractory metal or its compound, such as Nb thin film, with or without another thin film of a wiring metal, such as Au thin film, may be further formed on the Ge thin film.
    • 为了实现相对于GaAs半导体具有实际令人满意的特性的欧姆电极,首先形成在n +型GaAs衬底上的是厚度在8nm和30nm之间的Ni薄膜,厚度在2nm和6nm之间的In薄膜 nm,厚度为10nm〜50nm的Ge薄膜。 之后,形成Ni薄膜,In薄膜和Ge薄膜的n +型GaAs衬底在300-600℃的温度下退火几秒钟至几分钟。 结果,欧姆电极具有包括从n +型GaAs衬底,InGaAs层和NiGe薄膜再生长的n ++型再生长的GaAs层的多层结构。 或者,在退火之前,可以在Ge薄膜上进一步形成难熔金属或其化合物(例如Nb薄膜)的薄膜,其具有或不具有诸如Au薄膜的布线金属的另一薄膜。

    • A facsimile machine provided with a data processing device for executing data processing in communications mode in accordance with a command entered from a communications apparatus having a capability of transmitting and receiving communications data. The facsimile machine includes a mode select device for switching itself from ordinary facsimile mode for image data transmission and reception to communications mode for communications data transmission and reception in accordance with an operator input; an operation judgment device for judging whether the data processing device has accomplished a printing job, in which data received from the communications apparatus is printed on paper, after the mode select device has switched the facsimile machine to communications mode; and a mode reset device for resetting the facsimile machine to facsimile mode when completion of the printing job has been confirmed by the operation judgment device.
    • 一种传真机,其具有数据处理装置,用于根据从具有发送和接收通信数据的能力的通信装置输入的命令在通信模式下执行数据处理。 该传真机包括一个模式选择装置,用于根据操作者输入自身从用于图像数据发送和接收的普通传真模式切换到用于通信数据发送和接收的通信模式; 操作判断装置,用于在模式选择装置将传真机切换到通信模式之后,判断数据处理装置是否完成了从通信装置接收到的数据被打印在纸上的打印作业; 以及用于在通过操作判断装置确认完成打印作业时将传真机复位为传真模式的模式复位装置。

    • A facsimile apparatus which enables the printer section and document original reading section thereof to be used as a printer and image reader, respectively, for a personal computer. To use the reading section for reading a document original as the image reader for the personal computer, the operation mode of the facsimile apparatus is switched from an ordinary operation mode to a PC-FAX mode. When a document original is read by the reading section in the PC-FAX mode, the facsimile apparatus behaves as if it received a call-in of facsimile correspondence, and sends image data to the personal computer. Further, by operating an operation section, a printer function call number is registered for an external input printing function which enables information input to an interface to be printed out. When a call-out command designating a phone number is sent to the facsimile apparatus from the personal computer, a control section judges if the phone number agrees with the printer function call number. If the input number agrees with the printer function call number, information input from the personal computer is printed out by a printer section.
    • 一种能够使打印机部分和文档原稿阅读部分分别用作个人计算机的打印机和图像读取器的传真装置。 为了使用读取部分读取原稿作为个人计算机的图像读取器,传真装置的操作模式从普通操作模式切换到PC-FAX模式。 当在PC-FAX模式中由读取部分读取原稿时,传真装置的行为就好像接收到传真通信的呼入一样,并将图像数据发送到个人计算机。 此外,通过操作操作部分,为外部输入打印功能注册打印机功能呼叫号码,该外部输入打印功能使能够输入到要打印的接口的信息输入。 当指定电话号码的呼出命令从个人计算机发送到传真设备时,控制部分判断电话号码是否与打印机功能呼叫号码一致。 如果输入号码与打印机功能呼叫号码一致,则从个人计算机输入的信息由打印机部分打印出来。
