  • Publication number: 20240052584
    Abstract: Provided is a block compactor equipped with a brake mechanism capable of securely locking rollers with a simple structure and stably maintaining a locked state and an unlocked state even when exposed to vibration. A brake pad 12 is fixed to a lower end portion of a brake shaft 11 and is configured to be rotatable together with the brake shaft 11 between two rollers 5 adjacent in the front and rear. By rotating a brake lever 13, the brake pad 12 can be switched between an unlocked state in which the brake pad 12 does not contact with the outer circumferential surfaces of the rollers 5, and the rollers 5 are free to rotate, and a locked state in which the brake pad 12 contacts with the outer circumferential surfaces of the rollers 5, and the rollers 5 cannot rotate with the friction force.

  • Patent number: 9443808
    Abstract: A semiconductor wafer includes circuit integration regions each incorporating an integrated circuit and guard rings disposed to surround the circuit integration regions, respectively. A scribe region disposed between every adjacent two of the guard rings. An element and a pad electrically connected to the element are disposed in the scribe region. A groove is disposed along a corresponding guard ring on a front surface of the semiconductor wafer between the pad and the corresponding guard ring. The distance between the groove and the pad is varied along the corresponding guard ring.
