  • Publication number: 20240109202
    Abstract: An end effector attachment apparatus is an apparatus to be attached to an end effector of a robot. The end effector attachment apparatus includes a base plate, a mount plate on which the end effector is mounted, an attraction mechanism for attracting the mount plate to the base plate, and a bellows coupling the mount plate to the base plate. The front and rear edges of the bellows are sealed to the base plate and the mount plate to secure a sealed space inside the bellows.

  • Patent number: 8458633
    Abstract: A semiconductor integrated circuit design apparatus for analyzing a delay in a semiconductor integrated circuit. The semiconductor integrated circuit includes a delay analysis unit, a noise generation unit, a voltage fluctuation level analysis unit and a timing verification unit. The noise generation unit generates noise information based on a predetermined noise definition and the voltage fluctuation level analysis unit analyzes a voltage fluctuation level of the semiconductor integrated circuit when the noise is applied based on the generated noise information. Further, the timing verification unit makes the delay analysis unit analyze the static delay based on the analyzed voltage fluctuation level, to verify timing for operation of the semiconductor integrated circuit based on a result of the static delay analysis.
