  • Patent number: 8840115
    Abstract: A seal system for a reciprocating cylinder includes a buffer seal, a rod seal, and a wiper seal. The buffer seal includes a dynamic seal lip and a static lip extending from a hinge portion. The hinge portion of the static lip allows fluid to escape past the outer diameter of the seal when the rod is retracted thereby releasing any pressure build-up between the rod seal and buffer seal. The axial face portion of the dynamic seal lip includes axially extending notches therein. The notches prevent the buffer seal from sticking to the axial wall of the groove and provide a consistent path for the fluid to energize the annular groove between the static and dynamic lips during the extension phase which is necessary for the function of the seal. The back-up ring is an integrated part of the buffer seal, used to provide superior extrusion resistance.

  • Patent number: 8612790
    Abstract: A serial data transfer apparatus includes a transport controller that performs a process of a transport layer, a link controller that performs a process of a link layer, and a physical layer circuit that performs a process of a physical layer. The serial data transfer apparatus transmits and receives data with a destination apparatus via a serial bus. The link controller outputs idle data, which is received from the destination apparatus, to the physical layer circuit, and stops to operate of a unit responsible for generating data to transmit to the destination apparatus while outputting the idle data to the physical layer circuit. This enables to output idle data defined in the standard in an idle period of the serial data transfer apparatus and also reduce the power consumption.

  • Publication number: 20130327395
    Abstract: An oxide evaporation material according to the present invention includes a sintered body containing indium oxide as a main component thereof and cerium with a Ce/In atomic ratio of 0.001 to 0.110. The L* value in the CIE 1976 color space is 62 to 95. The oxide evaporation material with the L* value of 62 to 95 has an optimal oxygen amount. Accordingly, even when a small amount of an oxygen gas is introduced into a film-formation vacuum chamber, a transparent conducting film having a low resistance and a high transmittance in the visible to near-infrared region is formed by vacuum deposition methods. Since the amount of the oxygen gas introduced is small, the difference in composition between the film and the evaporation material is made small. This reduces the variations in composition and characteristics among films formed in large quantities.
