Abstract: PURPOSE:To obtain the captioned copying paper for which the color-fading of a developed character is prevented and which has a printing aptitude by employing phenolic resin and acid terra alba together as a developer, calcium carbonate as a pigment, and PVA and the like as an adhesive agent. CONSTITUTION:Phenolic resin (preferably paraphenyl phenol resin) and active terra alba (preferably the acid terra alba or the like from which an acid-soluble basic constituent is melted out and whose surface area is turned to be 200m<2>/g or more) are employed together, preferably in the weight ratio of 1:1-5, as a developer, while calcium carbonate being used as the main ingredient of a pigment, and polyvinyl alcohol and styrene-butadiene latex as an adhesive agent. On the occasion, PVA is used, preferably, in 30pts.wt. or more, in particular, in 50-200pts.wt. to 100pts.wt. of phenolic resin. It is coated on the substrate paper and thus the aimed no-carbon copying paper is obtained. EFFECT:Copying paper thus obtained suffers little yellowing from sun light and nitrogen oxide.

Title: Method for producing easily dipersible pigment granule
Inventor: KAARU ROOTO
IPC: C09B67/00
Filed: 1992-04-23
Abstract: PURPOSE: To obtain readily dispersible pigment granules with small inclusion of dust by dispersing, in an aqueous suspension of the pigment, a gas which does not react with the suspension in fine bubbles and converting the resulting pigment suspension into pigment granules through spray drying, mechanical removal of a liquid, shaping of a pigment cake or the like. CONSTITUTION: In an aqueous suspension of a pigment, under vigorous stirring, a gas which does not react with the suspension is dispersed in fine bubbles essentially without additional pressure. Then the resulting pigment suspension is converted into pigment granules by spray drying or by mechanical removal of a liquid, shaping of a moist pigment cake and subsequent drying. In this case, air or the like is used as the gas which does not react with the suspension. Readily dispersible pigment granules of all organic and inorganic pigments are produced thereby. Besides the pigment granules with small inclusion of dust and yet simply dispersible are produced with ease.

Title: Pre-mixed gas burner
Inventor: NAKAMOTO MITSUYOSHI
IPC: F23D14/14
Filed: 1985-05-17
Abstract: PURPOSE:To reduce the amount of NOX by constituting a burner for pre-mixed gas with flat plates and corrugated plates between them and providing suitable grooves in the flat plates and the corrugated plates. CONSTITUTION:Pre-mixed gas 4 is introduced through a fuel gas inlet 5 and led to a pre-mixing chamber 3. After the flow of the pre-mixed gas 4 is regulated, it is supplied uniformly to many fuel passages 14. After this, the direction of flow of the gas 4 is changed at right angle to flow into a flame opening section 15, and then it is supplied to a combustion chamber 13 from the end section 16 of the flame opening. The flame opening section 15 is formed opposite to the combustion chamber 13, and when the pre-mixed gas 4 is ignited, opposing flames 19 are formed. The opposing flames consist of a pair of flame faces 24 and 25. Between them a stagnation point 20 is formed. When the flames are stable, combustion at the stagnation point is finished, and there is no flow speed and it is insulated by the flame faces 24 and 25. Accordingly the stagnation point 20 contributes to stability of the flames 19, and it is more so when the flow rate of the pre-mixed gas is larger. With this arrangement, when the flow rate of the pre-mixed gas is large, stability of opposing flames is increased, and when the flow rate of the pre-mixed gas is small, backfire is prevented, much widening thereby the range in which it is possible to have stable combustion.
