Filed: 1990-11-05
Abstract: PURPOSE:To prepare a thin hand bone material by a method wherein a kaolin mixed with a pigment is dispersed in a fiber-dispersed water and made into a paper-like shape to obtain a kaolin paper which is calcined after drying and is ground. CONSTITUTION:A fiber-dispersed water is obtd. by putting simply a fiber into water and stirring and mixing them by a proper means such as a high speed mixer. A kaolin is dispersed in the fiber-dispersed water by means of e.g. a stirring rod or a ball mill. The dispersion is made into a paper and dehydrated and calcined after drying. As org. fiber is burned to be voids by calcination, when an org. fiber is used, the product becomes porous and the bulk density becomes small. On the other hand, when a clay mineral such as zeolite is used, it is calcined with kaolin and the product becomes dense and the bulk density becomes large. For example, a clay as the kaolin and a iron oxide as a pigment are used and dispersed into water and the dispersion is made into a paper in such a way as a paper making and the paper is calcined after drying and is ground thereafter to obtain a pattern-developing aggregate material with a thickness of 0.5-1.0mm, a surface diameter of 1-20mm and a brown color.

Abstract: PURPOSE:To improve a working speed by dividing an amount of movement in unit time, by redistributing amounts of divided movement evenly selected frames of acceleration time, further by totalizing redistributed pieces of the amount of movement for each unit of time to calculate a speed command. CONSTITUTION:Assume an amount of movement of a control object to be 400 and its target speed to be 50 per unit of time, respectively, to divide the amount of move ment 400 per unit of time. The amount of movement 400 is divided into 8 unit time frames A-H. Next, acceleration time is specified for each unit time frame. In this case, the amount of time is redistributed by 10 each into continuous 5 unit time (acceler ation time) frames A-E. Next, an amount of movement 50 for unit time frame B is also evenly divided and redistributed into nit time frames B-F by 10 each. Likewise, an amount of movement 50 for each of unit time frames C-F is sequentially redistribut ed. Redistribution of an amount of movement for frame E is done by newly adding unit frame I whose initial distribution of an amount of movement is zero and by doing the distribution for frames E-I. Redistribution of amount of movement for frames F-H is also done by sequentially adding new unit time frames J-L. When all the redistributions are terminated, all amounts of movements are totalized for each of frames A-L.
