Filed: 1990-11-28
Abstract: PURPOSE:To eliminate generation of creases by making the above seamless belts hard to stretch under a high temperature, by a method wherein a coating layer of synthetic having the high modulus of elasticity is formed on an etching- treated surface of a tube made of fluorine resin having thermoflowability, the inside of which is comprised by being etching-treated. CONSTITUTION:It is necessary that the inside of a tube made of thermoflowable fluorine resin is etching-treated and then a coating layer consisting mainly of synthetic resin having the high modulus of elasticity is formed. The etching treatment is easily treatable by a method wherein an alkaline metallic solution consisting mainly of metallic sodium or metallic sodium-naphthalene complex, for example, is filled for a fixed time or passed. The present method is a method where after a resin solution 2 is filled into a tube 1 by actions of nip rolls 3, 3 and a cylindrical guide 4, the tube 1 is taken off at a speed by passing the same through the cylindrical guide 4 and cut into appropriate size by a disklike cutter 5. With this construction, the resin solution 2 acts upon the inside of a long-sized tube semicontinuously.

Filed: 1990-11-29
Abstract: PURPOSE:To enable a sorting machine to recede from its position on a closable lid simply with light force by pushing the sorting machine in the width direction of a printing/developing device on the upper face of the printing/developing device so as to move the sorting machine by support members and arm members. CONSTITUTION:With the parallel movement of a sorting machine 50, arms 62 are turned in the direction B to rotate shafts 66, 67. A crank 86 is moved in the direction C by the rotation of a crank 80, and when the end part of the caster 56 side is moved parallel into its receding position from its position on a closable lid 48, the movement of the crank 86 in the direction C and its opposite direction is blocked to stop the turning of the arms 62 in the B direction. The sorting machine 50 is not therefore positioned on the closable lid 48 of a printing/developing device 10 to make the closable lid 48 closable. The sorting machine 50 can be thereby moved from its position on the closable lid 48 into its receding position simply with light force.

IPC: C01B31/04
Filed: 1997-12-03
Abstract: PROBLEM TO BE SOLVED: To obtain an oil absorbing material attained in excellent forming workability and having excellent oil absorbing ability by oxidizing a carbon fiber formed material with an acid and an oxidizing agent and after that, heating. SOLUTION: A method for producing an expanded graphite from the carbon filter formed material is constituted of a process for producing a graphite intercalation compound by oxidation reaction and a process for expanding by heating. The carbon fiber formed material means a formed material using a carbon fiber (e.g. ccbon fiber woven fabric, carbon fiber felt, carbon fiber mat or the like). As the oxidizing method of the carbon fiber formed material, a chemical dipping process, electrolytic oxidation process and the like may be cited, but the chemical dipping method is preferable in the view point of productivity and cost. The method uses a mixture of a concentrated acid with a strong oxidizing agent. As the oxidizing agent, nitric acid, hydrogen peroxide, potassium dichromate, peroxo ammonium disulfate and the like are exemplified.  The expanded graphite is obtained by heating the graphite intercalation compound after being oxidized at 500-3,000 deg.C under atmospheric pressure or reduced pressure.
