Inventor: HATADA TSUYOSHI
IPC: D06M101/16
Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To attain exact control of the reduction rate of polyester fiber, as the embritllement of cellulosic fiber is suppressed in cellulosic fiber-blended polyester fiber woven or knitted fabric by controlling the reduction of the polyester fiber with an alkaline solution that is kept its alkali concentration constant, as the concentration of the terephthalate salt is used as an index. SOLUTION: The valve 16 is opened to charge an alkaline aqueous solution of sodium hydroxide with <=15 g/l, preferably 5-10 g/l concentration, into the reaction vessel 10. Simultaneously, the standard value of the initial alkaline concentration, the concentration of the terephthalate salt X and the concentration of the terephthalate salt concentration Z at the target reduction rate are calculated and memorized to the CPU 22. The knitted or woven fabric of polyester fibers blended with cellulosic fibers as rayon is charged in a reaction vessel to start the alkali-reduction and the alkali concentration in the vessel is continuously measured and the values are input to the CPU 22.  The alkali solution is automatically fed via valve 16 in order to maintain the above standard value and, when the concentration of terephthalic acid X reaches the same concentration of Z, the CPU outputs the signal of the reaction stopping to complete the treatment.

IPC: B05D7/00
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To accentuate a embossed pattern by coating the surface of a base material, that is provided with an embossed pattern, with a coating material of a predominant color and thereafter subjecting only the rising parts of the embossed pattern of the surface to spray coating with another coating material of another color that belongs to the same family as that of the predominant color and has lower brightness as compared with the predominant color, through spraying the coating material of the color having lower brightness on the surface of the material in one oblique direction to the surface. SOLUTION: In this method, a panel which is e.g. a ceramic based exterior panel and provided with a embossed pattern formed in its surface by press forming or the like, is firstly coated with a coating material of a dominant color 3. At this time, the whole surface of a base material 1 is uniformly coated by roll coating or spray coating, however, when the difference in height between the projecting parts and the recessed parts is small, the surface is thinly coated so as not to bury the recessed and projecting parts with the resulting coating film.  Then, another coating material of another color which is used as a silhouette 4 of the dominant color 3 of the surface of the base material 1, and also, belongs to the same family as that of the dominant color 3, and further, has lower brightness as compared with the dominant color 3, is sprayed on the surface of the base material 1 in one oblique direction to the surface so that only the rising parts of the embossed pattern of the surface is preferentially coated. Thus, shade and shadow of the embossed pattern become clear to increase the stereoscopic effect of the pattern and to accentuate the pattern.

IPC: H01M4/14
Filed: 1979-04-10
Abstract: PURPOSE:To prevent the abnormality of an enclosed and high-output type storage battery with a small amount of electrolyte due to overdischarge, by inserting hollow acid-proof fibers between positive and negative plates. CONSTITUTION:Hollow acid-proof fibers are inserted between postive and negative plates. For example, the hollow acid-proof fibers are mixed with a separtor material such as resin-reinforced pulp, hydrophilic polyethylene fibers, or glass fibers and are made into paper. Alternatively, the above-mentioned fibers may be sprayed and adhered on the surface of a molded separator with a binder. As the above-mentioned fibers, it is desirable that they are acid-proof and water-proof. It is also desirable that their hollow spaces are each not more than 100mu in diameter and their lengths are each 100 times as long as the diameter of the hollow space, especially the former is 1-10mu and the latter is 1-10mm. For example, as mterials, glass, polypropylene, polyester, polyacrylonitrile, etc. are used. This enables an enclosed or high performance storage battery with a small amount of electrolyte to be held between plates to improve the retention of the liquid sulfuric acid between the plates and also prevents its abnormality.
