Abstract: A winding liner for an unvulcanized rubber material includes a belt-shape inextensible loading member for loading an unvulcanized rubber material and spacers provided at both widthwise direction sides of one surface of the loading member along a lengthwise direction of the loading member. The loading member and the spacers are made of metal and are formed into a plate shape having flexibility. The spacers have protruding portions protruding from the one surface of the loading member, the protruding portions being disposed at predetermined intervals in the lengthwise direction of the loading member.

Abstract: Provided is a method and device for producing, efficiently with high productivity, a winding liner with a spacer for an unvulcanized strip rubber member as well as a method and device for producing a spacer member for the winding liner. A plate-shaped strip material (RW) is unwound from a material unwinding roll (16), then caused to pass between forming gears (19a and 19b) of a forming device (19) so as to be continuously formed in a shape of protrusions and recesses. An adhesive member (14) is attached to a surface of each of the strip spacer members (12a and 12b) each formed in the shape of protrusions and recesses. Then, the adhesive surfaces of the respective spacer members (12a and 12b) are continuously stuck along the longitudinal side edge portions of a plate-shaped base member (11) unwound from an unwinding device (45).

Abstract: An abrasive composite material containing a matrix, abrasive grains, and carbon fiber having a multi-layer structure, each fiber filament of the carbon fiber having an outer diameter of about 2 to about 500 nm and an aspect ratio of about 5 to about 15,000, and including a hollow space extending along its center axis. Preferably, the carbon fiber has a BET specific surface area of about 4 m2/g or more; the carbon fiber has, at a carbon (002) plane, an interlayer distance (d002) of about 0.345 nm or less as measured by means of X-ray diffractometry; and the ratio of the peak height (Id) of the band at 1,341 to 1,349 cm−1 in a Raman scattering spectrum of the carbon fiber to the peak height (Ig) of the band at 1,570 to 1,578 cm−1 in the spectrum; i.e., Id/Ig, is about 1.5 or less. More preferably, the carbon fiber contains branched vapor grown carbon fiber; boron is contained, in an amount of about 0.

Abstract: Cubic boron nitride crystals are grown by subjecting reaction materials of low pressure phase boron nitride, a solvent material, and cubic boron nitride seeds to pressure and temperature conditions in the cubic boron nitride-stable region. The reaction materials are in the form of a pair of a superimposed solvent material plate and a low pressure phase boron nitride plate or a pile made of a plurality of the pairs of the superimposed solvent material plate and low pressure phase boron nitride plate, and a plurality of the seeds are disposed on either one or each of the confronting surfaces of the pair of the superimposed solvent material plate and low pressure phase boron nitride plate. Alternatively, the reaction materials are in the form of a plate made of a mixture of the solvent material and the low pressure phase boron nitride or a pile made of a plurality of the mixture plates, and a plurality of the seeds are disposed on a surface of each plate. The seeds have a particle size of not larger than 150 .

Abstract: Diamond crystals are grown by subjecting reaction materials of nondiamond carbon, a solvent metal, and diamond seeds to pressure and temperature conditions in the diamond-stable region. The reaction materials are in the form of a pair of a superimposed solvent metal plate and a nondiamond carbon plate or a pile made of a plurality of the pairs of the superimposed solvent metal plate and nondiamond carbon plate, and a plurality of the seeds are disposed on either one or each of the confronting surfaces of the pair of the superimposed solvent metal plate and nondiamond carbon plate. Alternatively, the reaction materials are in the form of a plate made of a mixture of the solvent metal and the nondiamond carbon or a pile made of a plurality of the mixture plates, and a plurality of the seeds are disposed on a surface of each plate. The seeds have a particle size of not larger than 50 .mu.
