Abstract:
PROBLEM TO BE SOLVED: To provide a nonaqueous pigment ink composition having excellent adhesion and alcohol resistance after printing. SOLUTION: In this nonaqueous pigment ink composition essentially comprising (1) an organic solvent, (2) a high molecular compound, and (3) a pigment, (1) the organic solvent consists of at least one kind of solvent selected from a group consisting of (1a) glycol ethers and glycol ether acetates, and (1b) 1,3-dimethyl-2-imidazolidinone, a content of the former (1a) is within a range of 35-94 wt.% in the whole ink composition, and a content of the latter (1b) is within a range of 3-30 wt.% in the whole ink composition. In the nonaqueous pigment ink composition, 1-15 wt.% vinyl chloride-vinyl acetate copolymer is contained as (2) the high molecular compound, and a concentration of (3) the pigment is 2-20 wt.% in the whole ink composition.

Abstract:
PROBLEM TO BE SOLVED: To provide a titanium dioxide dispersing element for a dye sensitized solar battery which can be manufactured by a simple and low cost method, a titanium dioxide thin film formed by using the dispersing element and the dye sensitized solar battery manufactured by using the thin film. SOLUTION: The titanium dioxide dispersing element for the dye sensitized solar battery is composed containing a cellulose system or a butyral system additive with terpineol, alcohols, glycol ethers, or glycol ether acetates as an independent or mixed solvent. In this case, an organic titanium compound or a niobium compound is added to these dispersing elements. Furthermore, the titanium dioxide and polyvinyl butyral resin are made into solid chips with two rolls and the chips are dissolved and produced. In addition, the titanium dioxide thin film formed by using the titanium dioxide dispersing element, and the dye sensitive solar battery manufactured by using the film is manufactured.

Abstract:
PROBLEM TO BE SOLVED: To provide an oil-based uniform dispersion composition of a pigment having sufficient dispersion stability and service environmental durability as an ink, etc., for preparing various kinds of recordings or displays or display-related elements as an oil-based dispersion composition of the pigment by uniformly dispersing various kinds of pigments in an oil-based medium, especially a silicone oil with a specific dispersing agent and to establish a method for producing the composition. SOLUTION: The oil-based uniform dispersion composition of the pigment is characterized as follows. A dispersion medium which is an essential component is a silicone oil consisting essentially of dimethylpolysiloxane and a dispersoid which is the essential component is an inorganic or an organic pigment. A dispersing agent which is the essential component is selected from a polyoxyethylene-methylpolysiloxane copolymer and a polyvinylbutyral in selecting the essential components of the oil-based uniform dispersion composition of the pigment.

Abstract:
PROBLEM TO BE SOLVED: To provide a fabric printing ink that gives high wash-fastness, reduces the number of steps required for printing and environmental load and renders a fabric excellent touch, perspiration absorption and appearance, and a printing method. SOLUTION: The fabric printing ink is manufactured to have a composition which comprises 8 wt.% carbon black, 1.6 wt.% pigment dispersant, 6 wt.% resin emulsion, 20 wt.% diethylene glycol, 0.1 wt.% acetylene glycol and 0.1 wt.% triethanol amine. An image is formed by jetting the ink on a fabric by an inkjet process. The ink is fixed on the fabric by ironing at a temperature of 180°C for 40 seconds. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide a low-cost and long-life electron source device with a high electron emission capacity. SOLUTION: The electron source device is provided with a porous insulating layer (for instance, a porous alumina layer) equipped with a number of microholes (nano-holes) arrayed in a vertical direction, a first conductor layer arranged on the face of a opening side of the nano-holes, a conductive layer made inside the nano-holes consisting of a conductor or a semiconductor, and a second conductor layer and a bottom side end part of the nano-holes and the second conductor layer are separated by a barrier layer made of a dielectric. It is so structured that electrons are emitted in a direction contrary to the direction headed from the second conductor layer to the barrier layer by voltage impressed between the first conductor layer and the second conductor layer.
