摘要： The invention relates to a latex rubber product obtained by forming and vulcanizing latex which is prevulcanized in the presence of a compounding agent for vulcanization containing a vulcanizing agent of sulfur or sulfur-containing compound, and is deprived of free compounding agents not spent in prevulcanization by centrifugal separation. This product is reduced in the ash content in combustion and is hence useful for reducing the refuse, and is particularly suitable for use in radiation contamination preventive rubber gloves which are incinerated after use for disposal. Besides, since the amount of sulfur oxide generated in combustion gas is decreased, it is also effective for prevention of air pollution and measure against acid rain. Moreover, since the compounding agents irritating the skin are removed, it is safe in application as gloves or the like.

摘要： Pneumatic tire including a puncture sealing layer which is applied to an inner lining and in which by addition of specific amounts of polyisobutylene and of a particular form of silica with respect to a set amount of polybutene and by use of powdered elastomer having a specific particle size distribution there are achieved optimum values of viscosity and adhesivity and ability to seal even large puncture holes in a wide range of temperature and operating conditions. In addition there is less tendency for puncture sealing layer components to migrate to the inner lining and tire durability is therefore improved.

摘要： PROBLEM TO BE SOLVED: To reduce residual distortion, improve seismic tracking ability and mounting work, and reduce cost, by using as an elastic material a rubber composition containing a rubber component and metal salt of α, β unsaturated carboxylic acid. SOLUTION: A base material rubber of an elastic washer 1 contains various diene-based rubber, the other rubber component, preferably cis-1,4-polybutadiene rubber, and natural rubber, polyisoprene rubber, or mixture of them as further rubber component. A metal salt of α, β unsaturated carboxylic acid, especially preferably used ethylenic unsaturated carboxylic acid is a metal salt of (meta) acrylic acid or crotonic acid, and its mixing amount is 10-100 pts.wt. to 100 pts.wt. of the rubber component. The structure discussed above reduces residual distortion than a washer made of conventional rubber composition, prevents occurrence of looseness, softens this washer, allows tracking even when opening is large, and increases compression elastic coefficient by 10% to improve fastening efficiency.

摘要： PURPOSE: To easily set a detector for measuring the weight of a traveling vehicle by applying a specified voltage to a conductive rubber detection plate with its volume resistant value changing with respect to the treading load of the vehicle and detecting a flowing current. CONSTITUTION: A weight detection part 3 is provided with a rubber detection plate 31 set on a traveling road surface. This detection plate 31 is made of a conductive rubber material having a characteristic of its volume resistance value changing with respect to the treading load of a tire. When a pressure is applied in such a state that electrodes are attached to both ends of the detection plates 31 and a direct current is applied, a volume resistant value increases almost linearly. Thus, by detecting a current flowing to the detection plate 31 at this time, the weight of the vehicle can be calculated. Further, since the volume resistant value of the conductive rubber decreases with a temperature increase, a volume resistant value-temperature curve can be measured beforehand, a temperature of the rubber detection plate 31 from a volume resistant value in an unload state in which no vehicles exist can be calculated and from this temperature the volume resistant value can be calculated beforehand.

摘要： PURPOSE:To obtain a belt with rubber tooth and its connecting method in which a permanent extension owing to a long period service, and an extension or contraction owing to the temperature variation, are hardly generated, the manufacture is easy, and the cost is low, by reinforcing with short fibers oriented in the peripheral direction. CONSTITUTION:A rubber made by mixing 25 pts.wt. of short fiber Kevlar cut fiber, 65 pts.wt. of a basic magnesium methacrylate, 2 and pts.wt. of dicumil peroxide, to 100 pts.wt. of an acrylonitrile-butadien rubber is extruded in a sheet form with the thickness about 0.9mm. This rubber sheet is vulcanized at 160 deg.C for 20min. in a metal mould with tooth. The sheet is cut in the width 3.2mm making the extruding direction in the peripheral direction, so as to obtain a belt with tooth having the fixed end. Belts 8A and 8B with tooth are connected to a belt lock plate 4. At the bottom 42 of the belt lock plate 4 whose both ends are connected to position sensors, recesses 41 with the pitch same as the teeth of the belt are provided, and the recesses 41 and the teeth at both ends of the belt are engaged and connected.
