  • Publication number: 20250029027
    Abstract: A digital twin simulation is executed. In this simulation, a personal relationship level between two workers included in multiple workers is calculated. Further, based on the personal relationship level between the two workers and data of work content of the work scheduled to be executed in a work line of a real space, an assignment pattern of workers satisfying a reference condition in which a work efficiency in a whole work line of a digital space is equal to or greater than a target value is searched.

  • Publication number: 20250021084
    Abstract: The operation management system manages an operation of a line composed of a plurality of cooperating work subjects. The operation management system performs: setting, for each work subject, an intensity that decreases at a speed corresponding to a work speed, recovers by a recovery action, and is given a lower limit value; receiving a target handling plan for the line; creating an operation plan including at least the working speed and a timing of the recovery action by using a simulation model obtained by modeling the line so that the target handling plan is achieved while maintaining the intensity of each work subject at the lower limit value or more; and allowing the intensity of each work subject to temporarily decrease to less than the lower limit value in creation of the operation plan in response to the target handling plan exceeding a predetermined reference value.

  • Patent number: 5384533
    Abstract: A testing method tests functions of a semiconductor integrated circuit which has a plurality of blocks each having a main block circuit part and an output part. The testing method comprises the steps of supplying a control signal to the output part of each of the blocks in a normal mode so that each output part outputs an output data of the main block circuit part of a corresponding one of the blocks, supplying the control signal and a test data to the output part of each of the blocks in a test mode so that each output part outputs the test data which is supplied to the main block circuit part of another block, and comparing the output data and the test data in the output part of each of the blocks in the test mode and outputting a failure detection signal which is indicative of a failure in a corresponding one of the blocks when the compared output data and test data do not match in the one block.

  • Patent number: 5124776
    Abstract: A semiconductor integrated circuit comprises a plurality of first hierarchical units of logic devices each including a plurality of bipolar logic devices having a polycell structure. The bipolar logic devices have a first standardized size in a first direction and are arranged in a second direction for a second standardized size in each first hierarchical unit. Each of the first hierarchical units is defined by first and second main edges extending in the second direction for the second standardized size, and first and second side edges extending in the first direction for the first standardized size. Each of the first hierarchical units consumes a generally identical electric power and has a first power feed system extending in the second direction for the second standardized size for feeding the electric power to the bipolar logic devices therein.

  • Patent number: 4975544
    Abstract: A connecting structure for connecting conductors used for wiring in a semiconductor device comprises a first conductor provided on a part of the semiconductor device for passing the flow of electrons, an insulator provided on the first conductor and formed with a contact hole, and a second conductor provided on the insulator for passing the flow of electrons, in which the second conductor is provided so as to sandwich the insulator together with a part of the first conductor. The first and second conductors are contacted to each other across the insulator at the contact hole so that the electrons flow through the contact hole. The contact hole extends in a general direction of a flow of electrons passing therethrough and has a stepped shape in which a width measured perpendicularly to the general direction of the flow of electrons increases stepwise towards the general direction of the flow of electrons.
