IPC: B41J2/05
Filed: 2000-03-08
Abstract: PROBLEM TO BE SOLVED: To provide a liquid jet recording head for enabling stabilized high speed continuous printing, a method of manufacture and a liquid jet recorder. SOLUTION: In the liquid jet recording head 10, liquid flowing into a common liquid chamber 22 through a liquid inlet 32 flows along the wall face 12B of a housing 12 and the heating element forming face 18A of a heating element substrate 18 and enters an individual channel 20, as it is. A liquid drop 36 is ejected through heating of a heating element 16.

Title: Discharge unit, charging device, image holding unit, image forming device and manufacturing method of discharge unit
Inventor: KOBU MAKOTO
IPC: G03G15/02
Filed: 2000-03-16
Abstract: PROBLEM TO BE SOLVED: To lessen ionized products, keep enough life of discharge electrode, and reduce damage to a charged body. SOLUTION: A plurality of discharge electrodes 22 are arranged protruding in a hemi-spherical shape on an electrode-fitting face 21a of a support member 21 made of an insulating member. When a voltage is applied between a feeding electrode 25 and a charged body 23, discharging points swing in a certain width as in the case of an acerous electrode without centering on one particular point, since the discharge electrode 22 has a nearly hemi-spherical domed part 22a. With this, the discharge electrode 22 is prevented from wearing at its specific point. Since the hemi-spherical discharge electrode 22 has fewer discharge points than a wire electrode discharge unit using metal wire, an ionized portion becomes proportionately fewer, hence, lessened ionized products.

Title: Waste treatment method and device therefor
Inventor: SASAKI HIROSHI
IPC: B01D19/00
Filed: 2000-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a waste treatment method by which solid organic waste can be efficiently and easily treated. SOLUTION: The solid organic waste is cracked and crushed to remove contaminants with a pretreatment means and made into a liquid organic waste in a mixing tank. After removing contaminants from the liquid organic waste, a nutritious salt is properly mixed in a solubilizing tank to prepare a mixed liquid having 5-20% TS concentration. The mixed liquid is treated by methane fermentation in a methane fermentation tank 1 and the produced gas is recovered. Ammonia is removed from part of the recovered produced gas by an ammonia removing means. The produced gas after ammonia is removed is jetted at a rate of 0.3-3 m3/m3/hr into a mixed liquid having pH of 7.0-8.5 in the methane fermentation tank 1 and stirred.  The produced ammonia shifts to the jetted produced gas and the concentration of ammonia in the mixed liquid becomes <=4,000 mg/l, which is equal to or above the ammonia concentration where ammonia inhibition occurs, to prevent the accumulation. Thus the methane fermentation efficiency is easily improved with the simple structure.
