  • Publication number: 20240079067
    Abstract: A semiconductor memory device includes an output pin configured for connection with a memory controller, an output circuit configured to output through the output pin a voltage signal that changes over time in accordance with one or more bits of data to be output to the memory controller, and a control circuit configured to temporarily change a drive capability of the output circuit each time a voltage signal corresponding to one bit of the data is output through the output pin.

  • Patent number: 7117575
    Abstract: In manufacturing a link plate for a roller chain, a band of sheet steel is intermittently forwarded along a path past series of dies, including rough punching dies and shaving dies. The punching dies and corresponding shaving dies are located symmetrically on opposite sides of an intermediate location along the path. The intermediate location coincides with a location at which the lateral deviation of the band reverses. Consequently, the outer peripheral surfaces of the plate and the inner peripheral surfaces of the connecting pin holes, both being formed by rough punching, are brought into very close alignment with the shaving dies.
