Abstract: The apparatus separates various contaminated waste-oils mixed with water, oil slag and other contaminants into waste matters and an oil and water mixture. The apparatus comprises  a  heat  medium boiler with piping (12), heating tank provided with a plurality of agitators  (2)  for  agitating   waste   oils,   transverse   type fentrifugal separator (3) having rotator (19) for separating waste matters  (18) from  oil-water  mixture,  storage  tank  (5)   for temporarily storing the mixture separated from the separator  (3), agitator (10) having the additive inlet for agitating the mixture, agitating tank (7) having outer circulation tube (16),  emulsifier rotated by 6000- 8000 RPM,  storage  tank  (9)  for  receiving  the refined oil from the tank (7).

Title: Compact sorter
Inventor: CHUNG JAE-HUN
IPC: B65H39/11
Filed: 1990-01-25
Granted: 1992-06-04
Abstract: The compact sorter for sorting copied papers  comprises  slot liners, a transfer wheel, and a number of bin  trays.  The  middle portion of the slot liner which is formed in each of  side  plates of the sorter body is bent toward the ejecting section of the copy machine within the radius of gyration of the  transfer  wheel,  in such a manner that the bin trays for  loading  the  copied  papers should advance one by one to directly below the  ejecting  roller, so that the ejected papers should be  exactly  received  into  the correct position of each of the bin trays. Vertical and horizontal movements of the bin trays are made to be possible, and  both  the bin tray which has completed the receiving of a copied  paper  and the bin tray which has been waiting are made to be  simultaneously moved.

Title: Word-line driving circuit
Inventor: DO JONG-KI
IPC: G11C11/407
Filed: 1990-03-09
Granted: 1993-04-03
Abstract: The circuit for using an accelerator  to  increase  the  word line driving voltage over cell operating voltage comprises a  NAND gate (1) receiving an address input signal, an NMOS transistor (4) having a gate connected to an output stage of the NAND  gate  (1), an NMOS transistor (3) having a gate connected to  the  NAND  gate (1) output through an inverter (2) and receiving an  input  signal (I1), an NMOS transistor (4) connected between the NMOS transistor (3) and power source (Vss), and connected to a word  line  (8)  of the  memory cells  (100-100n),  and  the  accelerator  (11).  The accelerator (11) includes a PMOS transistor (5) receiving an input signal (I2), an NMOS transistor (7) having a gate connected to the word line  (8),  and  a  PMOS  transistor  (6)  connected  to  the transistors (5,7).
