Publication number: 20100290845Abstract: A cutting edge portion intermediate form that is a pre-sintered body of the cutting edge portion and a supporting portion intermediate form that is a fully sintered body of the supporting portion are manufactured separately. Full sintering is then performed where front end portion of the supporting portion intermediate form is inserted into an insertion hole of the cutting edge portion intermediate form. During sintering, cobalt particles in powdered materials are converted into a liquid phase, and contracting occurs. Because the supporting portion intermediate form has already been fully sintered, only the cutting edge portion intermediate form contracts. The front end portion of the supporting portion intermediate form is squeezed by the cutting edge portion intermediate form. The carbide tip is therefore created in which the cutting edge portion and the supporting portion are strongly bonded.Type: ApplicationFiled: December 27, 2007Publication date: November 18, 2010Applicant: OSG CORPORAITONInventors: Youichiroh Shimoda, Mikio Fukuda

Publication number: 20100209684Abstract: A method with which a textile sheet having good mechanical properties in respect to relatively high values regarding tear propagation resistance can be produced. The textile sheets are used in areas that require relatively high tear propagation resistance. The textile sheets also have relatively high peak tensile values and/or elongation at break values. The method for the production of a tear propagation-resistant textile sheet comprises providing a starting textile sheet made of yarns, fibers or filaments formed of at least two elementary filaments and having an arrangement in cross-section like orange segments or pie slices with the segments or slices made of different polymers, and exposing the starting textile sheet to a compressing heat treatment, wherein the polymer segments are permeated and a substantially non-adhesive bond is achieved between the polymer segments. The textile sheet may comprise nonwoven materials having a specific tear propagation resistance of equal to or greater than 0.Type: ApplicationFiled: July 2, 2008Publication date: August 19, 2010Applicant: CARL FREUDENBERG KGInventors: Robert Groten, Ulrich Jahn, Georges Riboulet, Michael Hess, Ameur Abdelkader

Patent number: 7740790Abstract: A method of making a thermotropic liquid crystal polymer film includes continuously heat treating of the thermotropic liquid crystal polymer film 2 while the latter is jointed to a sheet-like support member 4, and subsequently separating the heat-treated thermotropic liquid crystal polymer film 2 from the support member 4. The continuous heat treatment of the thermotropic liquid crystal polymer film 2 then jointed to the support member 4 is carried out for a predetermined heating time within the range of 5 to 60 seconds at a predetermined heating temperature T° C. equal to or higher than the melting point Tm° C. of the thermotropic liquid crystal polymer film less 15° C. (i.e., Tm?15° C.), but lower than the melting point Tm° C. (thus, Tm?15° C.?T° C.<Tm° C.), to thereby increase the thermal expansion coefficient of the thermotropic liquid crystal polymer film.Type: GrantFiled: September 23, 2004Date of Patent: June 22, 2010Assignee: Kuraray Co., Ltd.Inventors: Minoru Onodera, Tatsuya Sunamoto
