Abstract: Logic emulation according to the present invention is aimed at an object to provide a logic dividing and module wiring system for operating logic related to external interface signals and interface signals among circuits obtained as a result of division or a logic circuit at a high speed. In a logic emulation system, information on assignments of external interface signals of logic to connector pins is read in during division of the logic. Logic related to an external interface signal assigned to a connector pin is assigned to a field programmable gate array directly connected to the connector pin. In addition, delays are checked after the division of a logic circuit in order to determine the level of delay criticality of each interface signal between field programmable gate arrays. Wiring of a module is then carried out in accordance with the levels of criticality.

Abstract: A logic emulation system that verifies a target logic circuit and evaluates its performance efficiently divides the design data of a target logic circuit into a plurality of small-scale logic circuits and a connection circuit for interconnecting the small-scale logic circuits, thereby creating an equivalent circuit of the target logic circuit. The logic emulation system judges, when a logical design change to the target logic circuit prompts the comparison of the data of the equivalent circuit of the logic circuit before the logical change with the data after the logical change, whether it is feasible to implement the design data on the logically changed logic circuit by adding one or more small-scale logic circuits, and by altering the connection circuit accordingly.

Abstract: A portable trimmer has a supporting tube extending straight forward from an engine at its rearward end to a cutting device at a forward end. A handle-bar is mounted on a middle portion of the supporting tube at an intersecting point. First and second grips extend upwardly from two corresponding ends of the handle-bar. The handle-bar has a first portion extending from an intersecting point to the first grip, and a second portion extending from the intersecting point to the second grip. The first portion extends across a width of an operator's body, and is bent in a rearward direction. The supporting tube has an inclination with respect to a phantom line connecting the first and second grips such that said cutting device is located in front of a center of the operator's body when the operator holds the grips in a natural posture. This portable trimmer increases the area in which weeds can be cut in a single movement, and provides for easy handling.

Abstract: A portable trimmer has a supporting tube with a forward end on which is mounted a cutting device. The cutting device has a case with a first hole for receiving a stick, and also contains a rotatable shaft with a threaded end. A seating member that is rotatable with the shaft has a second hole that can be aligned with the case's first hole. A rotatable cutter is removably mounted on the rotatable shaft, fixed to against the seating member by a nut that engages the shaft's threads. The stick is inserted into the first hole in the case and the second hole in the rotatable seating member, to prevent rotation of the seating member during assembly and disassembly. The cutting device retains the stick in the first and second holes even when the cutting device is upside down. This retention is accomplished, either by a biasing member that biases the stick in a direction perpendicular to the axis of the first hole, or by an elastic member that frictionally engages the stick in the hole.

Abstract: A program data creating method and apparatus for use with programmable devices in a logic emulation system provides high-speed logic emulation of an LSI for logic and function verification. The logic data defining the logic circuits of the LSI is divided into a plurality of unit blocks in a layout analogous to the floor plan represented by floor plan information for the LSI. The unit blocks are allocated to the programmable devices automatically. The names of the signals defined within the design data regarding the LSI are made to correspond with the names of the signals in effect when the design data is deployed within the programmable devices, after optimization of the logic. This allows the program data for the programmable devices to be created and corrected using the signal names as set forth in the design data.

A checking unit determines whether the designated logic blocks are accommodated in one programmable chip, and a division processing unit determines which logic blocks are to be assigned and the order of assignment priorities when the designated logic blocks are not all accommodated in the same programmable chip.

Abstract: A process control system of the type arranged to accept varied forms of analog sensing signals from field sensing devices, to digitally process data represented thereby, and to supply varied forms of analog control signals to field control devices. The system is characterized by signal converter means which convert data between the varied analog forms generated by the field devices and a standard form of intermediate signal, e.g., a pulse-width signal, which carries data as a function of duration. The intermediate signals facilitate signal transmission, editing, and isolation, and permit the process control system to have a simple, noise-free, easily adaptable structure. Digital interface means then convert data between the intermediate signals and digital signals in a form suitable for use by digital data processing means.
