Title: Cyclic digital filter
Inventor: NISHIKAWA AKINARI
IPC: H03H17/02
Filed: 1988-03-31
Abstract: PURPOSE:To reduce the influence of the error due to the rounding of data against the digital output data by adding the prescribed data having the mean value '0' with no same value obtained continuously more than the prescribed frequency to the digital input data. CONSTITUTION:The random number data on the integers produced by a random number generator 15 are superposed on each other via an adder 12. Thus the random numbers are added to the input data and therefore the continuous input of data on '0' are substantially avoided even though the input data have '0' continuously. Thus it is possible to omit such a conventional inconvenient case where the data are kept at the fixed value. In addition, the random number data on the integers produced by the generator 15 has the mean value '0' and therefore only the frequency characteristic are obtained by a cyclic digital filter when the digital output data is defined in terms of the frequency characteristics. Then the influence of the error due to the rounding of data can be reduced to the digital output data.

Filed: 1995-02-24
Abstract: PURPOSE: To enhance construction properties by causing a pair of endless crawler belts which face each other while sandwiching a casing to be pressed into contact with the casing, and rotating the crawler belts for movement of the casing in the direction in which the casing is press fitted in or drawn out. CONSTITUTION: A casing 1 is driven into weak ground to a predetermined depth together with a drain material 2, and is then drawn out with an end cone and the drain material 2 left in the ground to form a drain column. In this case, a pair of endless crawler belts 5 is pressed into contact with the casing 1 and is driven by a hydraulic motor 13 or the like to rotate so as to move the casing 1 in the direction in which it is press fitted or drawn out.

Title: Treatment of ash formed in coal-burning fluidized-bed boiler
Inventor: MATSUMURA HIROYUKI
IPC: B09B1/00
Filed: 1983-04-30
Abstract: PURPOSE:To make the titled ash usable for reclamation disposal without the formation of environmental pollution, by kneading combustion ash collected by a dust collector out of combustion ash formed during burning a fluidized bed comprising coal and limestone with the specified amount of water to granulate it, and then maturing it in a CO2-contg. atmosphere. CONSTITUTION:In adopting a fluidized-bed combustion system comprising coal as fuel for a boiler or the like and limestone as a desulfurizing agent, formed combustion ash contains CaO and CaSO4 formed by desulfurization, and combustion ash esp. collected by an electric dust precipitator or a cyclone has the small efficiency of reclamation and causes the formation of environmental pollution because of the increase of the pH of excess water when it is used for reclamation. Therefore, said combustion ash is kneaded with sea or fresh water of 20-70% as the mixing amount of water, granulated to particle size of 2-30mm. and then matured in a CO2-contg. atmosphere for 0.1-24hr. Hence, the efficiency of reclamation is enhanced, and the surfaces of incorporated CaO and Ca(OH)2 are reacted with CO2 to form a CaCO3 coating layer. Consequently, the amount of an alkali component exuding in sea water is reduced to eliminate the cause of environmental pollution.
