  • Patent number: 8177591
    Abstract: A terminal fitting 10 includes a main body 20 to be coupled to a mating conductor, and a crimp contact section 30 rearward from the main body 20. The crimp contact section 30 is crimped on an end of a core wire 42 in a covered electrical cable 40 so as to surround the end. The core wire 42 includes a plurality of metallic strands 41 and is covered with a sheath 43 to form the covered electrical cable 40. Serrations 34 are provided on a contact surface of the crimp contact section 30 for surrounding the core wire 42. Each serration 34 is a polygonal shaped recess with which the core wire 42 engages upon crimping. Both diagonal corner portions 34C of each serration 34 are rounded. Thus, the whole periphery of an opening edge around the recess penetrates an oxide layer on a core wire.

  • Publication number: 20110281069
    Abstract: A glass substrate obtained by a method including measuring flatness of a glass substrate surface and measuring concentration distribution of dopant in the substrate. Processing conditions of the surface are set up for each site of the substrate based on results from the measuring the flatness and the measuring the distribution, and the finishing is carried out while keeping an angle formed by normal line of the substrate and incident beam onto the surface at from 30 to 89°. The surface is subjected to second finishing for improving an RMS in a high spatial frequency region. The surface after the second finishing satisfies the requirements: an RMS slope in the region that 5 ?m<? (spatial wavelength)<1 mm is not more than 0.5 mRad and an RMS slope in the region that 250 nm<? (spatial wavelength)<5 ?m is not more than 0.6 mRad.

  • Patent number: 8051754
    Abstract: With the use of a tool (41), first cutting is applied to a work (W), and then second cutting is applied to the work (W) while the tool (41) is transferred in an X-axis direction. Then, an amount of deviation dy between the cutting edge height of the tool (41) and the center line of the work (W) is calculated based on a first diameter value (D1) and second diameter value (D2) measured after the first cutting and second cutting are applied, and the travel distance of the tool (41) between the first cutting and the second cutting. Machining to the work (W) is resumed after the amount of deviation is corrected.
