Title: Image forming apparatus
Inventor: HIROKI MASASHI
IPC: B41J2/06
Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To provide an image forming apparatus having high ejection frequency and capable of forming a high density image of high quality free from blur. SOLUTION: An ink jet printer has the recording head arranged in opposed relation to a platen roller and the recording head has a plurality of ejection electrodes to which ink is supplied. A platen roller is set to predetermined potential VO and, in such a state that all of ejection electrodes are set to bias potential Vb, recording voltage Vp is applied to the electrodes selected corresponding to an image signal and ink is allowed to fly to form an image. When the above mentioned recording operation is completed, all of the ejection electrodes are returned to bias potential and the potential of the platen roller is controlled to cleaning potential V1. At this time, the cleaning potential V1 is determined so as to form Vp-VO<Vb-V1. By this constitution, the ink stagnated at an ejection point without being allowed to fly is allowed to fly by a stronger electric field and new ink is supplied.

Title: Impervious structural material
Inventor: NISHIYAMA KATSUE
IPC: E02B3/12
Filed: 1999-01-22
Abstract: PROBLEM TO BE SOLVED: To enable cement to surely drive onto the inclined surface even when cement content is reduced and exhibit impervious performance over a long period even when crack occurs by mixing a fiber into an impervious structural material. SOLUTION: An impervious structural material is driven so as to cover the upper surface of a piling up part 1a to build an impervious layer 21. The impervious structural material is bonded to a soil material comprising sand and gravel by mixing the material with polypropylene 22 and hardly made to flow because of stickiness and compensates initial strength, because the viscosity coefficient is increased. The impervious structural material can be driven in large amount, because the material remains on the slope 24 without flowing when driven onto the slope 24. Cement of the impervious layer 21 is solidified after passing about 1 month to exhibit strength. Cement can be added in a small amount of <=200 kg per m3 product.  When crack is produced in the bottom 5, unmodified bentonite 6 in the impervious layer 21 contains water and is swollen and penetrated into crack to block the crack and prevent leakage of water.
