Title: Self - cleaning fluid filter
Inventor: GERULIS BENEDICT R
IPC: B01D27/10
Filed: 1987-03-03
Granted: 1990-07-31
Abstract: Filter comprises a sheet metal cylindrical outer body with a fixed top plate having a central threaded outlet port surrounded by several smaller inlet ports sealed by a compressible outer ring. Contaminated fluid enters under pressure from the circulating pump and forces down the upper piston against the upper helical spring, thereby displacing filtered fluid trapped underneath the piston outwards through the filter element to form the backflush function. When the piston reaches the end of its travel it exposes the circulating port to allow the contaminated fluid passage through the narrow annular space to give the scouring action down the outer face of the filter element and deposit the accumulated contaminants in the space at the bottom of the canister.

Abstract: This invention concerns an oscillation circuit which  uses  a charge and discharge, utilizing the electric potential  change  of the transistor, and provides a low power  consumption  oscillation circuit that uses a bias circuit. This circuit is composed of  the resistances and transistors. A reference current  is  set  by  the resistors  (R11,R12)  and  transistor   (Q11),   and   transistors (Q13,Q16,Q21,Q26) are decided in order. The  currents  flowing  on transistors (Q12,Q18,Q22) are decided by the  transistor  Q13.  So low power consumption oscillation circuit is obtained.

Title: Memory arbitration apparatus
Inventor: YU DONG-KWAN

Abstract: a central processing unit(CPU) for arbitrating each bus use right of the CPU, a first controller and a second controller in accordance with the time when their request signals are reached and their priority order, when the request signals are transmitted to an arbitration circuit, and if a bus request signal is generated in the state where the first and second controllers do not have the bus use right, having the bus use right in a first state equation; the first controller having the bus use right in a second state equation, if the request signal by the first controller is generated in the state where the second controller does not have the bus use right and the bus request signal of the CPU does not exist; and the second controller having the bus use right in a third state equation, if the request signal by the second controller is generated in the state where the first controller does not have the bus use right and the bus request signals of the first controller and the CPU are completed.
