Title: Sheet curling straightening device and image forming device
Inventor: MATSUYAMA TORU
IPC: B65H29/70
Filed: 1998-12-15
Abstract: PROBLEM TO BE SOLVED: To provide a sheet curling straightening device capable of improving image quality. SOLUTION: This sheet curling straightening device 26A comprises a soft roller 28, hard roller 29 and roller support member 30. The hard roller 29 is pressed against the soft roller 28 enough to gnaw thereinto. The roller support member 30 is arranged on the lower side of the longitudinal direction center section of the hard roller 29 to support the roller 29 abutting on the hard roller 29 so that the roller 29 slides. A accumulation gap 28a is provided in the area X of the soft roller 28, which corresponds to the section with which the hard roller 29 and roller support member 30 are brought into contact to accumulate silicone oil, etc., therein. The silicon oil, etc., transferred to the soft roller 28 from a sheet P is absorbed in the accumulation gap 28a so as not to be accumulated on the section where the roller 29 and member 30 contacts each other.  This constitution eliminates non-uniformity in image brilliance and faulty image in curling straightening.

IPC: C09K23/50
Filed: 1991-12-02
Abstract: PURPOSE:To provide a condensate available for an admixture for giving concrete excellent in fluidity by polymerizing lignin sulfonic acid (salt), sulfanilic acid (salt) and formaldehyde at a specified weight ratio. CONSTITUTION:50-95 pts.wt. lignin sulfonic acid (salt), 2-40 pts.wt. sulfanilic acid (salt) and 1-15 pts.wt. formaldehyde are polymerized by heating them in the aqueous conditions to produce lignin sulfonic acid-sulfanilic acid- formaldehyde condensate. The obtained condensate is added as an admixture in the case of producing concrete, mortar or cement paste. Thereby, since entrained air bubbles are diminished by this admixture, a suitable air entraining agent is combined. Freezing and thawing resistance is enhanced by entraining fine air bubbles. Furthermore, delay of the setting time of cement composition is prevented and fluidity is enhanced and deterioration of fluidity based on elapse of time is reduced.
