Agent: Crowell & Moring LLP Intellectual Property Group

20070012173 - Engine component part and method for producing the same: An engine component is composed of an aluminum alloy containing silicon, and includes a plurality of primary-crystal silicon grains located on a slide surface. The plurality of primary-crystal silicon grains have an average crystal grain size of no less than about 12 μm and no more than about 50 μm.... Agent: Yamaha Hatsudoki Kabushiki Kaisha C/o Keating & Bennett, LLP

20070012174 - End cap assembly: A fluid activated cylinder assembly including an end cap having an annular protrusion and a hollow cylinder having an end zone. The cylinder applies compressive force to the annular protrusion in the end zone. The end zone having no accommodating cavity and no accommodating protrusion for the annular protrusion.... Agent: Barnes & Thornburg LLP

20070012180 - Component for insert casting, cylinder block, and method for manufacturing cylinder liner: A cylinder liner 2 is enveloped in a cylinder block through insert casting. The cylinder liner 2 includes a cylinder liner body 2a and a metal coating layer 8 formed on the body 2a through a cold spraying method. Since the metal coating layer 8 is formed in a non-molten... Agent: Kenyon & Kenyon LLP

20070012178 - Cylinder liner and engine: A cylinder liner for insert casting used in a cylinder block is provided. The cylinder liner includes an outer circumferential surface having a plurality of projections. Each projection has a constricted shape. A film of a metal material is formed on the outer circumferential surface and the surfaces of the... Agent: Kenyon & Kenyon LLP

20070012179 - Cylinder liner and engine: A cylinder liner has an upper portion and a lower portion with respect to an axial direction of the cylinder liner. A high thermal conductive film is provided on an outer circumferential surface of the upper portion. A low thermal conductive film is provided on an outer circumferential surface of... Agent: Kenyon & Kenyon LLP

20070012175 - Cylinder liner and method for manufacturing the same: A cylinder liner for insert casting used in a cylinder block is disclosed. The cylinder liner has an outer circumferential surface, and upper, middle, and lower portions with respect to an axial direction of the cylinder liner. A high thermal conductive film is formed in a section of the outer... Agent: Kenyon & Kenyon LLP

20070012176 - Cylinder liner and method for manufacturing the same: A cylinder liner has an outer circumferential surface on which a film is formed. The film functions to form gaps between the cylinder block and the cylinder liner. Alternatively, the film functions to reduce adhesion of the cylinder liner to the cylinder block. The cylinder liner suppresses excessive decreases in... Agent: Kenyon & Kenyon LLP

20070012177 - Cylinder liner, cylinder block, and method for manufacturing cylinder liner: A cylinder liner for an engine cylinder block. A roughening process is performed only on an upper region of the outer surface of the cylinder liner. This increases adhesiveness with a sprayed layer at the upper region compared to a lower region of the liner outer surface. Therefore, difference in... Agent: Kenyon & Kenyon LLP

20070006726 - Liner retention system: Apparatus and method for securing a cylinder liner to a pumping module. A first part of an assembly housing pistons is fastened to a pumping module and a second part of the assembly is brought against the first so that the pistons act on tensioning plates which each have a... Agent: Edwards & Angell, LLP

20070000379 - Pressure differential-driven engine: A pressure differential-driven engine (10) includes an outer pressurizable enclosure (12). A pressure barrier plate (14) is disposed within the outer pressurizable enclosure and an actuator enclosure (16) is disposed adjacent the pressure barrier plate and has an actuator (17) disposed therein. The actuator has a high pressure exposure surface... Agent: Thorpe North & Western, LLP.
