Abstract: A steering system for a vehicle includes a rack bar of which both end portions are connected to vehicle wheels and which extends in a width direction of a vehicle body, a motor configured to provide a force, and a gear assembly provided between the rack bar and the motor to transmit the force provided by the motor to the rack bar, wherein the gear assembly includes an input shaft configured to receive the force from the motor, an output shaft configured to transmit the force received through the input shaft to the rack bar, and a seal member provided on an outer circumferential surface of at least one of the input shaft and the output shaft.

Abstract: Disclosed herein is a pinion sensor structure of a steering apparatus including a housing including a first accommodating part having an open one side surface and configured to accommodate a worm wheel and a second accommodating part configured to communicate with the first accommodating part and accommodate a worm shaft engaged with the worm wheel, a sensing unit disposed to be spaced a predetermined distance from the worm wheel to face the worm wheel, and a housing cover coupled to the one side surface of the first accommodating part, wherein the sensing unit may be fixed to the housing cover.

Abstract: The invention relates to a process to manufacture advanced cellulosic gasolines. Dilute organic acids derived from pyrolized biomass are converted to their corresponding alcohols in a stand-alone hydrodeoxygenation unit followed by membrane pervaporation step to remove water. The alcohol product is blended directly into a neat hydrocarbon fuel basestock to make unadditized gasoline.

Abstract: This invention relates to a process for production of transportation fuels from biomass. More particularly, this invention relates to a process for using solvent to remove metal impurities and high molecular weight components from biomass derived biocrude to prevent potential catalyst poisoning and catalyst bed plugging in biocrude-to-transportation fuel upgrading process.

Abstract: A method of synthesizing diacetylenic amides is described. The key steps of the invention include the reaction of an aldehyde with the monoanion of a diacetylene and the reductive removal of a propargylic alcohol. The invention offers the first known method of synthesizing diacetylenic amides that are naturally isolated from Echinacea through a direct and flexible route.
