Filed: 1999-05-24
Abstract: PROBLEM TO BE SOLVED: To prevent the elution of noble metals from a waste reclamation layer by arranging a ventilation means on the upper surface of the reclamation layer, controlling the ventilation of the means corresponding to the pH value in a waste layer formed in the upper part of the means, and confirming the reducing atmosphere in the layer similarly by an ORP value. SOLUTION: An intermediate earth cover layer 4 is formed on an existing waste reclamation layer 3, and a ventilation pipe 9 having numbers of ventilation holes used as a leachate drain pipe in common is arranged in a tree branch shape in the upper part of the layer 4. Air is supplied by the pipe 9 while leachate is collected/discharged, waste is damped in the upper part, and numbers of waste layers 10 and covering earth layers 11 are formed in turn. After that, the pH and ORP values of leachate from the pipe 9 are measured occasionally, the pipe 9 is closed when the pH value has been neutralized by the dissolution in the leachate and chemical reaction of carbon dioxide in ventilation air, and the intrusion of air into the reclamation layer is prevented so that it is made anaerobic promptly. It is confirmed by the ORP value of the leachate that a reducing atmosphere is made.

Title: Measuring device
Inventor: ANDOU TOSHISHIGE
IPC: G01R31/28
Filed: 1980-10-14
Abstract: PURPOSE:To reduce the time for measurement by holding the limit voltage value for the purpose of protecting an object to be measured, and starting the measurement by changing the voltage from the assigned value. CONSTITUTION:When the output current of a constant current circuit 2 is positive, the voltage value of a variable clamp register 8 is fed into a positive D/A converter 10 by a switch 14, by which a digital value is converted to an analog quantity. This analog quantity is amplified by an operational amplifier 12 by which the assigned value is maintained. When the terminal voltage connected to the object to be measured exceeds the assigned value, the current is absorbed and is clamped to the assigned value. The limit voltage value of a positive clamp register 7 is changed over by the switch 14 and is amplified by the amplifier 12, by which the limit voltage value is maintained. When the terminal voltage connected to the object to be measured exceeds the limit voltage value, the current is absorbed and is clamped at the limit voltage value. For example, when a select switch S1 is changed over to S2 upon ending of measuring of the object to be measured connected to a measuring terminal T1, the voltage of the assigned value is applied to the object to be measured, by which the time for charging a capacitor C0 is reduced. The same holds true of the case when the output of the circuit 2 is genative.

Title: Rolling mill
Inventor: HACHITSUKA TAKASHI
IPC: B21B27/03
Filed: 1986-06-19
Abstract: PURPOSE:To improve the detachability and clamping force by installing a taper sleeve between a roll shaft and a wear resistant ring and forming an oil groove on the peripheral face of the sleeve. CONSTITUTION:A sleeve 4 is firmly fixed to a roll 3 by shrinkage fitting. The peripheral face of the sleeve 4 is pressed in the axial direction by the inner peripheral face of the roll 3 to generate compressive stress in the direction of arrow Y in the sleeve 4. Tensile stress canceling the compressive stress is generated in the sleeve 4 when the roll 3 and sleeve 4 are press fitted into a taper part 2 and are fixed. Therefore, the tensile stress in the sleeve 4 is remarkably reduced with the consequent result that the force pushing the roll 3 and sleeve 4 into the part 2 is enough to resist against only a friction force between the sleeve 4 and the part 2 and the assembling work efficiency of the roll 3 is improved. The stress in the sleeve 4 is very small, although the sleeve is strongly pressed by the part 2. Therefore, the roll 3 is firmly fixed to the part 2 by the friction resistance between the roll 3 and part 2.
