  • Publication number: 20200225136
    Abstract: A thread guide wear testing machine wears a test piece by causing a thread to slide while the thread contacts the test piece. The thread guide wear testing machine includes a winding reel winding the thread thereon fed from thread feeder. A winding drum guides the thread fed from the thread feeder to the winding reel. The winding drum has an outer peripheral surface contacting an outer peripheral surface of the winding reel. Specimen holder is on a path of the thread fed from the thread feeder and moves while being wound on the winding reel. The specimen holder holds the test piece in contact with the thread under a predetermined load. Tension adjuster adjusts tension on the thread when the test piece is in contact. Contact retainer retains a state of contact between the winding reel and the winding drum by pressing the winding reel toward the winding drum.

  • Publication number: 20200199702
    Abstract: A steel sheet has a composition containing, in mass %, from 0.60 to 1.25% of C, 0.50% or less of Si, from 0.30 to 1.20% of Mn, 0.030% or less of P, 0.030% or less of S, from 0.30 to 1.50% of Cr, from 0.10 to 0.50% of Nb, from 0 to 0.50% of Ti, from 0 to 0.50% of Mo, from 0 to 0.50% of V, from 0 to 2.00% of Ni, the balance being Fe with unavoidable impurities. A ferrite phase as a metal matrix has dispersed therein cementite particles and Ni—Ti based carbide particles. A number density (cross section parallel to rolling and thickness directions) of the carbide particles having a circle equivalent diameter of 0.5 ?m or more is from 3,000 to 9,000 per mm2 and a number density of voids having a circle equivalent diameter of 1.0 ?m or more is 1,250 per mm2 or less.

  • Publication number: 20180202022
    Abstract: A steel sheet for textile machinery parts manufactured at a low cost and is excellent in wear resistance and toughness. The steel sheet for textile machinery parts contains, in mass %, 0.60% or more and 1.25% or less C, 0.50% or less Si, 0.30% or more and 1.20% or less Mn, 0.03% or less P, 0.03% or less S, 0.30% or more and 1.50% or less Cr, and 0.10% or more and 0.50% or less Nb, with the balance being Fe and unavoidable impurities. Furthermore, Nb-containing carbides having a particle size of 0.5 ?m or more are present in the matrix at a density of 3000/mm2 or more and 9000/mm2 or less. Nb-containing carbides' effect of improving wear resistance can be ensured, and deterioration in toughness due to excessive formation of Nb-containing carbides can be prevented. Hence, the resulting wear resistance and toughness are good.

  • Publication number: 20090249205
    Abstract: A display position determination apparatus has a selection unit selecting a first part from a parts group of display objects, an acquisition unit acquiring display occupancy in a display screen for each of said display objects, a judgment unit judging whether a balloon for the first part selected by said selection unit can be displayed within a non-display area or not in said display screen where no parts group is displayed; a search unit searching a second part from said parts group based on the display occupancy acquired by said acquisition unit when said judgment unit judges that the balloon cannot be displayed in said non-display area, and a determination unit determining that the display area of the balloon for said first part is within the display area of the second part searched by said search unit.

  • Publication number: 20020008719
    Abstract: When various image data etc. published on a Web are used in an application of a client, a system of inserting all necessary information into the application only in a simple operation such as a dragging-and-dropping operation, etc. is provided. The utilization of the local disk resources of a client can be further improved by referring to target information on a Web. In a client connected to a network such as Internet, etc., the system includes: a unit for inserting image data into the application of the client by dragging and dropping or copying and pasting each type of image data etc. displayed on the Web browser in the client; a unit for obtaining the URL on which the image data are published, and the information about the image data, and managing them as the attribute of the image data.
