Title: Recovering method of trifluoromethane sulfonic acid
Inventor: TERADA ICHIRO
IPC: C02F1/469
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To efficiently remove a metallic ion from a solution containing a metallic salt of trifluoromethane sulfonic acid by using an electric dialyzing vessel, in which a cation exchange membrane and a hydrogen ion-selectively permeable ion exchange membrane having an anion exchanger layer facing the anode side are arranged between an anode and a cathode. SOLUTION: A solution containing the metallic salt of trifluoromethane sulfonic acid is supplied to a desalting section 1 between the cation exchange membrane C and the hydrogen ion-selectively permeable ion exchange membrane H of the anode side, an acidic aq. solution is supplied to a concentrating section 2 of the cathode side of the cation exchange membrane C and the power is supplied. Then, a metallic ion produced by the dissociation of the metallic salt is permeated through the cation exchange membrane C, moves to the concentrating section 2, formed into a salt and removed with the acidic aq. solution. The hydrogen ion-selectively permeable ion exchange membrane selectively permeates only hydrogen ion and the anion produced by the dissociation of the metallic salt moves to anode, but is unable to be passed through the cation exchange membrane C.  As a result, trifluoromethane sulfonic acid is formed in the desalting section 1.

Title: Apparatus for supporting printing stage of printer
Inventor: ITO HIROSHI
IPC: B41J11/20
Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To uniform a head gap between a printing stage and a printing head by restricting vibrations of the printing stage. SOLUTION: Both ends of a printing stage 3 are supported by supporting members 1, 2. The printing stage 3 is secured at the vicinity of a center thereof to a coupling member 6 by a coupling jig 11. Accordingly, the printing stage 3 is restricted not to vibrate at the printing time. A long hole 9 provided for securing the vicinity of the center of the printing stage 3 by the coupling jig 11 is formed in the coupling member 6 set to the supporting member 1 supporting the end of the printing stage 3, and therefore, a relative positional relationship of the long hole 9 to the printing stage 3 is correctly set. Further, the long hole 9 accepts a relative positional shift of the coupling jig 11 in a longitudinal direction of the printing stage 3, thus enabling the printing stage 3 to be supported at the both end parts and the vicinity of the center without an extraordinary force applied.  A head gap between the printing stage 3 and printing head can thus be uniformed irrespective of a position of the printing stage 3 in the longitudinal direction.
