Title: Method for granulating dehydrated cake and concentrated sludge
Inventor: IKEGAMI YOSHIHIRO
IPC: B01J2/00
Filed: 1982-04-02
Abstract: PURPOSE:To granulate dehydrated cake and concd. sludge to a desired and uniform grain size which is suited for post treatments by disintegrating said cake and sludge and granulating the disintegrated material further by using a known granulator. CONSTITUTION:Dehydrated cake or concd. sludge produced by a dehydration treatment of industrial waste water and sewage is disintegrated with a disintegrator 2 and the disintegrated material produced by said disintegration is further granulated by using a known granulator 4 in a method of granulating said cake and sludge so as to be made suitable for post treatments. The method is more advantageous if the dehydrated cake of particularly a high moisture content is disintegrated and granulated after dried powder such as dust collecting ash or lime powder is added thereto. In other words, the fine particles in the disintegrated material are granulated to spherical particles of a desired size, and the other particles can be formed to a roughly spherical shape by rounding the corners thereof, whereby the disintegrated material having a uniform grain size is obtained. Since the fine particles are granulated to a specified size, the production of dust in succeeding handling is suppressed.

IPC: G06F9/445
Filed: 1990-03-07
Abstract: PURPOSE:To use a slow ROM as a program ROM and to improve the performance of a system by providing this system with a direct memory access (DMA) mechanism, and at the time of resetting the system, writing the program of the ROM in a high-speed RAM. CONSTITUTION:When a system reset signal is applied, a microrpocessor (MP) 1 is held at a reset state, and when a reset signal is released, the program stored in the slow program ROM 4 is written in the high-speed program RAM 3 while holding the MP 1 at the reset state as it is. After ending the writing operation, the reset state of the MP 1 is released and the DAM mechanism 2 is disconnected from the MP 1. After releasing the reset state, the MP 1 fetches the program stored in the RAM 3 and rises. Since the slow-speed ROM with low cost and large capacity can be used as the program ROM, the system of high performance can be obtained.

SOLUTION: In a continuous casting apparatus of molten metal, the molten steel is poured together with the lubricant into the water-cooling mold, and the produced solidified shell is drawn out to obtain the cast slab. The wave motion is generated on the surface of the molten steel in this mold and the deoxidizing elements of Ti, Al, etc., or these oxides are added in the fine grain state at about 0.01-0.02 wt.% into the lubricant from one position or more, and while mixing into the molten steel from the interface, the casting is executed. It is desirable that this wave motion on the molten steel surface is formed by supplying the alternating current composed of two levels of current value groups periodically varying the amplitude or the wave length to solenoid type electromagnetic coil arranged on the mold to impress the electromagnetic force into the molten steel. In this way, the oxide is finely and uniformly dispersed into the molten steel and the fine structure is formed to improve the quality.
