Title: Method and device for treating waste water containing carbonic acid together with boron
Inventor: KITANI HITONORI
IPC: C02F1/42
Filed: 2001-08-10
Abstract: PROBLEM TO BE SOLVED: To prevent inhibition of boron adsorption by carbonic acid (H2 CO3 , HCO3 or CO3 ) in waste water caused when waste water containing boron is treated by a boron adsorbing resin and to avoid such problems that the amount of boron adsorbed and removed per unit volume of the resin is decreased resulting in requiring exchanging of the resin in the treating tower in a short time even when the waste water contains a substantial amount of carbonic acid. SOLUTION: Boron is removed from the waste water in a first process of passing the waste water containing carbonic acid together with boron through a first ion exchange tower packed with a strong acidic cation exchange resin adjusted to an H-type to adsorb and remove cations, in a second process of passing the liquid through a second ion exchange tower packed with an anion exchange resin adjusted to an OH-type to remove anions except weak acid, and in a third process of passing the liquid through a third ion exchange tower packed with a strong basic anion exchange resin adjusted to an OH type or packed with a mixture resin of a strong basic anion exchange resin and a strong acidic cation exchange resin adjusted to an H-type to adsorb and remove boron.  In the above method, a process of decarbonating is carried out between the first process and the second process and/or between the second process and the third process.

Title: Belt for continuously variable transmission
Inventor: AOYAMA HIDEAKI
IPC: F16G5/16
Filed: 2001-08-10
Abstract: PROBLEM TO BE SOLVED: To solve various problems occurring when the metal belt of a continuously variable transmission is transferred and assembled, and assure a radiating property of a metal element, during the operation of the continuously variable transmission. SOLUTION: In this metal belt of the continuously variable transmission, the lateral outer end b1 of a metal ring assembly 31 is positioned nearer a neck part 36 side than the lateral outer end (a) of an ear part 37 in such a state that the lateral inner end of the metal ring assembly 31 is allowed to abut on the neck part 36. When the metal belt is transported in a unit or assembled in the continuously variable transmission, the contact of an other object with the lateral outer end b1 of the metal ring assembly 31 is prevented by the lateral outer end (a) of the ear part 37 to prevent the metal ring assembly 31 from being damaged. In addition, the metal ring assembly 31 is prevented from being fallen out of a ring slot 35.  In addition, since the entire lateral area of the metal ring assembly 31 is opposed to the lower surface 45 of the ear part, sufficient amount of oil is held on the opposed surface to increase the cooling effect of the metal element 32.
