    • The invention relates to the field of materials sciences and relates to a method such as can be used, for example, for producing molded articles from metallic glasses. The object of the present invention lies in disclosing a method and an apparatus in which a good mold filling during casting is achieved in addition to high cooling rates. The object is attained by a method in which a metal-containing melt is introduced into an electrically conducting casting mold, the metal-containing melt and the mold being connected in an electrically conducting manner to the outputs of the same voltage source during the introduction into a casting mold, so that a preset current flows through the boundary interface between the melt and the mold. The object is furthermore attained through an apparatus in which there is an electrically conducting connection to a voltage source between a metal-containing melt and an electrically conducting mold for the melt.

    • A mechanism controller for controlling power to motors of a mechanism having several motors, such as a robot. Each motor has a resolver for indicating the motor position. A driver unit is associated with each motor to supply power to the motor. Each driver unit includes a monitoring unit to monitor indications from the resolver of the associated motor. In one embodiment a control unit is connected to the driver units in a series circuit to control power to the motors and to receive the monitored indications from the monitoring units. In a second embodiment, the control unit is connected to the driver units in a ring circuit, rather than in a series circuit. Preferably, each driver unit also includes a memory device, and the control unit can send commands to the driver units and receive data from the driver units in sets equal in number to the number of driver units so that the commands and data do not need to include the addresses of the specific driver units. Alternatively, the commands and data can include a driver unit address so that the commands and data can be individually sent, rather than sent in sets.
    • 一种用于控制具有诸如机器人的几个电机的机构的电动机的机构控制器。 每个电机都有一个用于指示电机位置的旋转变压器。 驱动器单元与每个电动机相关联,以向电动机供电。 每个驱动器单元包括监测单元,用于监测来自相关电动机的旋转变压器的指示。 在一个实施例中,控制单元以串联电路连接到驱动器单元,以控制电动机的电力并从监控单元接收监视的指示。 在第二实施例中,控制单元以环形电路而不是串联电路连接到驱动器单元。 优选地,每个驱动器单元还包括存储器件,并且控制单元可以向驱动器单元发送命令并以与驱动器单元数相等的设置从驱动器单元接收数据,使得命令和数据不需要 包括具体驱动单元的地址。 或者,命令和数据可以包括驱动器单元地址,使得命令和数据可以被单独发送,而不是以套发送。
