    摘要： The present invention relates to a method and apparatus for distributed sensing utilizing optical scattering in optical waveguides and reveals two types of the invention. One type of the invention is to characterize optical scattering while actively controlling the temperature of the optical waveguide. The other type of the invention is to characterize optical scattering while strain/stress is induced into the optical waveguide through interaction of the jackets or coatings of the optical waveguide with objects under test. In one embodiment of the invention, the optical scattering based method and apparatus can sense liquid level, liquid distribution, and temperature gradient on ground and in low gravity. Other embodiments of the invention can detect location and concentration of liquid spill and gas leak along pipelines, or measure liquid or gas flow rates. Moreover, the method and apparatus described in the invention have capabilities of sensing multiple physical and chemical parameters using one sensing optical waveguide.

    摘要： A rotary cutter head for a surgical stapling instrument includes a staple cartridge, an annular cutter, a staple-pushing seat and a staple chamber. The staple-pushing seat and the annular cutter are connected by a bearing structure and provided with guide projections. The inner wall of the staple cartridge or the outboard of the expand-stopping tube is integral injection molded with a metal cylinder insert, on which is provided with a forward helix track and a backward track mutually independent and communicated with each other. The guide projections are mated with the two guide tracks and guiding the annular cutter to move along a helical path.

    摘要： The invention is a method of synthesizing Arylsulfur Trifluorides, such as Fluolead, by reacting BR2 and KF (or suitable alkali metal fluoride) in acetonitrile (or other suitable solvent). The invention also comprises using the Fluolead (or its substitutes), thus prepared, in situ as deoxofluorination reagents with a suitable aldehyde, ketone, or alcohol such as one selected from the group consisting of benzaldehyde Benzaldehyde, p-Bromobenzaldehyde, p-Tolualdehyde, Acetophenone, 2-Butanone, or Isobutyraldehyde, wherein the mixture is heated to reflux until completion. The respective products are then isolated after extraction by hexane and destruction of the sulfinyl fluoride co-product.

    摘要： In a linear guide apparatus, a rolling-element accommodation belt 50 is incorporated into each of endless circulation passages. This rolling-element accommodation belt 50 is formed into a shape having ends and has a plurality of rolling-element accommodation sections for individually accommodating balls 46. Of the rolling-element accommodation sections, first rolling-element accommodation sections 55A located at the respective end sections are formed so as to constrain movement of a spacer section 59 located at the end section toward the outer periphery side of an endless circulation passage by means of the ball 46 accommodated in the spacer section. Second rolling-element accommodation sections 55B other than the first rolling-element accommodation sections are formed so as to enable removable accommodation of the balls 46 to be accommodated toward the inner periphery side of the endless circulation passage.
