IPC: H01T19/00
Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device capable of stably obtaining an excellent image over a long period without requiring maintenance. SOLUTION: This image forming device having a corona electrifier 2 for electrifying a photoreceptor drum (image carrier) 1 is constituted by providing an air feeding duct (wind sending means) 45 feeding the clean air in the corona electrifier 2 and the exhausting duct (evacuating means) 51 for exhausting the air in the corona electrifier 2, so that a discharging wire 43 of the corona electrifier 2 is included in mid-way of a flowing path leading from the air feeding duct 45 to the exhausting duct 51, and a section in the flowing path lying along the photoreceptor drum 1 at a close range is not included on the downstream side of the discharging wire 43.

Title: Color filter, its manufacture and ink for color filter
Inventor: KAFUKU MASAAKI
IPC: G02F1/1335
Filed: 1994-12-12
Abstract: PURPOSE: To obtain a flat color filter, which can reduce a high cost resulted from a complex process and the loss of a material to be used, can unnecessitate the wet processing, and has excellent picture element shape, and an ink for the color filter. CONSTITUTION: A pattern is formed by ink jet system on a substrate 1 provided with a black matrix light shielding layer 2. At this time, it is preferable to previously apply an under coating of a silane coupling agent or the like on the substrate 1 since the adhesion of the substrate 1 to ink 3-5 is improved. Next, the surface is flattened by the surface tension of the ink itself at the temp. thereof by heating the substrate 1 itself formed by ink jet system or keeping the substrate in a high temp. atmosphere to induce remelting the ink 3-5. The heating process can be executed at the time of forming the pattern and the pattern can be formed simultaneously with three colors or alone with one color. The hardening process by energy beam (electron beam, ultraviolet ray, heat ray or the like) is, if necessary, executed after heat processing.

Filed: 1992-10-23
Abstract: PURPOSE:To enable the conversion of the impact pressure of a high velocity and high pressure by detonation to a liquid pressure or elastic pressure. CONSTITUTION:A combustion chamber 1 is so set that its sectional area diminishes gradually from one end 1A on progression of a flame. A convergent part having the min. sectional area is formed at the other end 1B. The liquid surface of liquid or the end face of the elastic body of a pressure chamber 12 faces the aperture of the other end 1B. A combustible gas and oxidizing agent are maintained under a prescribed pressure by compression chambers (buffer tanks) 9, 10 and are then mixed. The mixture is packed into an ignition chamber 4, a guide path 2 and the combustion chamber 1 and is then ignited. The sectional area of the combustion chamber decreases on progression of the flame in the combustion chamber 1 and, therefore, the pressure increases. An extremely high pressure is generated at the other end 1B. This high pressure is converted to the elastic pressure of the liquid or elastic body in the pressure chamber 12.

Title: Gas ultrafiltration membrane and its preparation
Inventor: KUMAMI KAZUHISA
IPC: B01D71/64
Filed: 1987-12-07
Abstract: PURPOSE:To capture and remove <=0.1mum fine particles from air, by the use of an ultrafiltration membrane having ventilative fine pores and <=100,000 fractional MW as an air filter. CONSTITUTION:An ultrafiltration membrane of polysulfone resins, polyimide resins having ventilative fine pores and <=100,000 fractional MW is used as an air filter. By using the membrane, <=0.1mum fine particles further about 0.01mum-degree particles are captured and removed from an atmosphere though it was hard conventionally. Even if a conventional ultrafiltration membrane with fractional MW <=100,000 for liquids is used in a gas phase, the membrane does not transmit any gases, e.g. air, at all. However, after immersing a conventional wet ultrafiltration membrane having fine pores on the surface in >=80 deg. hot water or pressured hot water or exposing to steam atmosphere and then drying, the pores become practically ventilative pores and the membrane becomes usable for an air filter.
