    摘要: The present invention provides a computer-aided design system and method for designing an application specific integrated circuit which enables a user to define functional architecture independent specifications for the integrated circuit and which translates the functional architecture independent specifications into the detailed information needed for directly producing the integrated circuit. The functional architecture independent specifications of the desired integrated circuit can be defined at the functional architecture independent level in a flowchart format. From the flowchart, the system and method uses artificial intelligence and expert systems technology to generate a system controller, to select the necessary integrated circuit hardware cells needed to achieve the functional specifications, and to generate data and control paths for operation of the integrated circuit. This list of hardware cells and their interconnection requirements is set forth in a netlist. From the netlist it is possible using known manual techniques or existing VLSI CAD layout systems to generate the detailed chip level topological information (mask data) required to produce the particular application specific integrated circuit.

    摘要: A rotary electrical machine connected to a rotary machine heated to high-temperature, such as a heater roll used for processing fibers, a ventilation fan for ventilating a high-temperature furnace, etc., includes a rotary shaft journaled by bearing means of the rotary electrical machine including a first member formed of material of low thermal conductivity for supporting a rotor, and a second member formed of material of high hardness constituting an output end portion of the rotary shaft remote from the bearing means. The first member and the second member are united together in a position located opposite the rotor with respect to the bearing means and spaced apart from the bearing means. Cooling means, such as a heat dissipating fan, heat dissipating fins, etc., is mounted on a portion of the rotary shaft between the vicinity of the joint of the two members and the bearing means. By this arrangement, a rise in the temperature of the bearing means of the rotary electrical machine can be avoided when the machine is connected to a rotary member of high-temperature, and the rotary member can be connected and disconnected readily and positively.
