A liquid application apparatus includes a rotatable coating cylinder having a circumferential surface onto which an application liquid is supplied; a base member which is conveyed continuously while making contact with the rotatable coating cylinder; a blade which scrapes off excess liquid of the application liquid in such a manner that a prescribed amount of the application liquid remains on the rotatable coating cylinder, before the rotatable coating cylinder transfers, onto the base member, the application liquid; a blade holding body which holds the blade, which is supported on a supporting shaft and is rotatable in a rotation direction; and a plurality of biasing devices which are disposed in an axial direction of the rotatable coating cylinder and bias the blade holding body in the rotation direction of the blade holding body in such a manner that the blade makes contact with the circumferential surface of the rotatable coating cylinder.

The ink jet recording method allows an electrostatic force to act on an ink composition containing at least charged particles containing a colorant and a dispersion medium to form a thread of the ink composition, and divides the thread into small portions to eject ink droplets on a recording medium. A first average concentration of the charged particles contained in the thread from its tip end portion to its central portion is higher than a second average concentration of the charged particles contained in a whole thread. And/or, a first force acting on the charged particles contained in the thread is made larger than a second force obtained by subtracting the first force acting on the charged particles contained in the thread from a second force acting on a whole thread.

摘要:
The three-dimensional image forming method prepares two or more kinds of ink, ejects and superimposes the two or more kinds of ink with an ink jet system on a supporting member and forms a three-dimensional image on the supporting member with the two or more kinds of ink ejected and superimposed on the supporting member. Each of two or more kinds of ink contains three-dimensional image forming particles different from each other in diameter. Further, the method forms the three-dimensional image that has been increased in filling factor. Alternatively, two or more kinds of ink contains a first kind of ink containing solid particles and a second kind of ink having physical properties that are different from physical properties of the solid particles.

An inkjet head is disclosed which an ink ejection unit and a plate including an ink ejection nozzle disposed in correspondence to the ink ejection unit. The plate contains fine particles that have a water-repellent function in at least a region near to a surface of the plate, the fine particles being dispersed therein. The plate is arranged by etching using at least two kinds of etching conditions which differ in magnitude relation between an etching rate of the fine particles in the region and an etching rate of portion of the plate excluding the fine particles in the region, to form the ink ejection nozzle and a surface of the plate in the vicinity of an ink ejection opening of the ink ejection nozzle. The fine particles, for example mainly comprises silicone. The surface of the plate formed by etching is a fine irregular surface where the fine particles are exposed, and an inner surface of the ink ejection nozzle formed by etching is a flat surface with no fine irregular portion.

An organic material-containing sludge is fluidized and is heat-treated at a high pressure in a reactor disposed underground to obtain an oil having a high calorific value. The heat treatment may be performed using an electrical energy, the terrestrial heat or a reaction heat obtained by oxidative treatment of similer sludge.

Hydrogen is produced from a cellulose-containing biomass by heating the biomass in the presence of water and a catalyst at a temperature of 250.degree.-374.degree. C. and at a pressure higher than the saturated vapor pressure of water. The catalyst includes a catalytic metal selected from the group consisting of nickel, iron, cobalt, molybdenum, tungsten, platinum and mixtures thereof.
摘要:
A layer-forming apparatus coats a solution containing a layer component and a flammable solvent on a surface of a base material, and forms a layer on the surface of the base material. In the layer-forming apparatus, a coating chamber in which the solution is coated on the surface of the base material is closed substantially hermetically, and a clean air is supplied from a clean-air supplier to the coating chamber. Then, ions that are produced by a corona discharger are sprayed to the surface of the base material in a state that a vapor concentration of the solvent in the coating chamber is below a burning lower limit, and dusts are removed from the base material. Then, the solution is coated on the surface of the base material from which the dusts are removed.
