摘要:
Devulcanized rubber in which sulfuric crosslinking bonds are cut and which contains carbon black particles having very small diameters. Vulcanized rubber of discarded products is devulcanized by heating it at a temperature of 180.degree. C. --350.degree. C. and applying a shearing pressure of 10-150 kg/cm.sup.2 thereto. Reclaimed rubber products are manufactured by vulcanizing and molding, into desired shapes, a material made of only devulcanized rubber in which sulfuric crosslinking bonds are cut and which contains carbon black particles having very small diameters or a material made of the devulcanized rubber mixed with virgin unvulcanized rubber.

摘要:
The present invention provides a rubber composition containing a reclaimed rubber and a method for producing the same. A rubber molded article having excellent rubber properties can be obtained and the recycling of a used rubber product can be promoted by the present invention. A rubber composition of the present invention is a blend comprising a claimed rubber obtained by applying a heat and a shear stress to a vulcanized rubber, a non-vulcanized virgin rubber or/and a thermoplastic resin, wherein the reclaimed rubber contains 40% by weight or more of a residual toluene-insoluble gel component and the network chain density of the rubber in the gel component is 1/20 to 1/4 based on the network chain density of the rubber of the vulcanized rubber.

摘要:
The object of the present invention is to provide a method of reclaiming crosslinked rubber wherein a reduction of qualities due to generation of decomposed products hardly occurs, and a molding of reclaimed rubber. In a reclamation step of reclaiming crosslinked rubber 10 by applying shear stress thereto and/or in a subsequent step in the present invention, a degasification carrier is introduced and decomposed products in the crosslinked rubber 10 are removed together with the degasification carrier. Also the disclosed is a molding of reclaimed rubber prepared by re-crosslinking reclaimed rubber obtained by this method.

A commodity sales data processing apparatus receives input of a comprehension degree which indicates the comprehension degree of a customer purchasing the commodity whose explanation is required by a salesperson if the sales data of the commodity whose explained is required by the salesperson is input through an input unit, and stores an information indicating the comprehension degree received in association with an identification information of at least one of the commodity and the salesperson.
摘要:
To provide an organic synthesizer that can conduct a pressure reaction and an atmospheric reaction in one organic synthesizer and can realize attachment of reaction vessels to the organic synthesizer and detachment of the reaction vessels from the organic synthesizer without applying any load to gas supply/discharge pipes. An organic synthesizer comprising a reaction vessel support part (160), which can support two or more reaction vessels, and pressure regulation means (164) for regulating the pressure within the reaction vessel supported by the reaction vessel support part (160) by supplying/discharging gas. Two or more pressure regulation means (164) are provided for each reaction vessel supported by the reaction vessel support part (160). At least one pressure regulation means (164A) in the two or more pressure regulation means (164) is constructed so as to be detachable from and attachable to the other pressure regulation means (164B). The pressure regulation means (164) comprises gas supply/discharge pipes (174a to 174d) and openings (194a to 194d) for supporting the gas supply/discharge pipes (174a to 174d). The gas supply/discharge pipes (174a to 174d) are constructed so that a part near the front end can be flexed in a vertical direction and in a lateral direction and are connected to the supported reaction vessels for gas supply and discharge.
摘要:
An interferometer of the invention includes: a first splitting element which includes a first transparent medium and a first splitting film formed on the first transparent medium, and which splits incident light into a first split beam and a second split beam, the first split beam being the incident light reflected by the first splitting element and the second split beam being the incident light transmitted through the first splitting element; and a second splitting element which includes a second transparent medium and a second splitting film formed on the second transparent medium, and which causes interference between the first split beam and the second split beam passed through different optical paths, the second splitting element being positioned such that a positional relationship between the second transparent medium and the second splitting film with respect to a direction of incidence on the second splitting element of the first split beam is opposite to a positional relationship between the first transparent medium and the first splitting film with respect to a direction of incidence of the incident light on the first splitting element.
