Filed: 1989-05-23
Abstract: A computer system includes a page memory in which a row address accompanied by a row address strobe (RAS) is followed by a column address accompanied by a column address strobe (CAS) to read data from a memory location during a memory cycle. When, in a following memory cycle, a further location from the same page is to be accessed, the row address and the RAS remain constant and a new column address is used with the CAS being precharged by switching it to its OFF state and then returning it to its ON state. This is normally done at the start of the following memory cycle. In the present system, the data is read and latched shortly after arrival of the column address and CAS in the first of the memory cycles so that the CAS recharge can take place at the end of the first memory cycle and before the start of the following memory cycle.

Patent SE-7514359-A (SE)
Inventor: HEISER J
IPC: F16K17/30
Filed: 1975-12-18
Abstract: A main valve controls the flow to a load in a first or second direction depending upon the signal applied to a pilot valve. A spool of the main valve is biased to a central position blocking flow by springs. A throttle valve having an adjustable restrictor area is connected in one line between the main valve and the load. The restrictor area is adjusted in correspondence to an input signal. The spool is moved to a first or second extreme position by the pilot valve. The pressure difference developed across the throttle valve is applied to the spool in a direction to force the spool towards the central position. The spool is balanced at a predetermined pressure difference across the throttle valve. A relief valve is furnished in an inlet line to the main valve so that a reversal of pressure medium flow through the load causes an excess pressure difference across the throttle valve and thereby moves the main valve spool to the other of its two operating positions in turn causing a substantial pressure increase in the inlet line causes operation of the relief valve and thereby braking of the load.
