  • Publication number: 20210061407
    Abstract: A hydraulic operating device is provided for a human-powered vehicle. The hydraulic operating device basically includes a base, an operating member and a handlebar mounting structure. The base includes a cylinder bore defining a cylinder axis. The operating member is pivotally coupled to the base about a pivot axis between a rest position and an operated position. The handlebar mounting structure is coupled to the base. The handlebar mounting structure defines a handlebar mounting axis that extends linearly along a handlebar in a mounted state. The cylinder axis is inclined towards the handlebar mounting axis as the cylinder bore extends away from the pivot axis as viewed in a pivot axis direction parallel to the pivot axis. The pivot axis is located in an area between the cylinder axis and the handlebar mounting axis as viewed in the pivot axis direction.

  • Publication number: 20190263938
    Abstract: A water-soluble hydroxyethyl cellulose is produced by reacting ethylene oxide with an alkali cellulose such that an average additional molar number of ethylene oxide per glucose unit of the alkali cellulose is 0.1 to 1.0 mol to prepare hydroxyethyl cellulose, and mechanically pulverizing the prepared hydroxyethyl cellulose. According to this producing method, it is possible to produce a water-soluble hydroxyethyl cellulose from an alkali cellulose with the usage of ethylene oxide reduced. In addition, the water-soluble hydroxyethyl cellulose produced by this producing method has a loss tangent (tan ?) of a 2% by mass aqueous solution of less than 1.0 in a frequency range of 0.1 to 100 rad/s in general, and exhibits a gel physical property.
