A method containing a step of reacting a conjugated diene polymer having an alkali metal or alkaline earth metal active end with a hydrocarbyloxysilane compound having one or more of each of the following functional groups I and II in its molecule to obtain a modified conjugated diene polymer containing a functional group II, and a step of mixing the modified conjugated diene polymer and a compound such as organic acid. A modified conjugated diene rubber which can be used as a raw material of a cross-linked rubber which can be used in tire treads and the like and can enhance low fuel consumption performance is provided. The functional group I is a hydrocarbyloxysilyl group. The functional group II is a nitrogen-containing group in which both of two hydrogen atoms of a primary amino group are substituted with protective groups.

Objects of the present invention are to provide a rubber composition that can obtain a rubber elastic body having small rolling resistance and excellent impact resilience and a method for producing the same, and to provide a tire having small rolling resistance and excellent impact resilience. The rubber composition of the present invention is obtained by kneading a rubber component containing 30 to 95% by mass of a conjugated diene polymer (A) and 5 to 70% by mass of cross-linked rubber particles (B) with 20 to 100 parts by mass of silica (C) based on 100 parts by mass of the rubber component.

A traction machine base includes a top member, a bottom member, a bottom member, first bolts, and second bolts. The top member is intended for supporting a traction machine. A plurality of attachment holes for fixing the top member are formed in the bottom member. A plurality of attachment holes for fixing the top member are formed in the bottom member. The first bolts pass through the attachment holes and fix the top member to the bottom member. The second bolts pass through the attachment holes and fix the top member to the bottom member. The top member is fixed to the bottom member using a smaller number of the first bolts than the number of the attachment holes. The top member is fixed to the bottom member using a smaller number of the second bolts than the number of the attachment holes.

This invention relates to a method of manufacturing a thermal laminate by laminating a first substrate film layer and a second substrate film layer through an adhesive resin layer, which involves the steps of, integrating the adhesive resin layer with the first substrate film layer, heating the surface of the adhesive resin layer by heat rays in the presence of oxygen to induce functional groups which contribute to adhesion, and then, superimposing the second substrate film layer on the adhesive resin layer to be bonded thereto with pressure. The thermal laminate has a strong laminated strength without using a solvent, and is excellent in the safety and hygiene of foods.

A wire member adapted to be used in a detection coil of an NMR spectrometer's probe. The wire member has a sleeve made of a copper tube having a high electrical conductivity, strands made of platinum, and a thin film of gold or rhodium formed on the surface of the sleeve by plating. The strands are mounted inside the sleeve and have a cross section to cancel the magnetic susceptibility due to the sleeve. The thin film cancels the total magnetic susceptibility of the sleeve and strands.

The present invention relates to a vacuum container having a first substrate and a second substrate arranged so as to face each other as components including, within the low-pressure container, a spacer disposed at the first substrate or the second substrate so as to maintain an interval between the first substrate and the second substrate. The spacer is fixed within the vacuum container via a supporting member provided at the spacer without contacting the substrate where the spacer is disposed. The invention also relates to a method for manufacturing vacuum container, an image display apparatus using the vacuum container, and a method for manufacturing the image display apparatus.
