Patent EP-0264272-A3 (EP)
IPC: F24F11/00
Filed: 1987-10-14
Abstract: Environmental heating/cooling systems are controlled by an 
interactive microprocessor and have continuous on-time and 
adaptive cycling modes wherein continuous on-time brings the 
temperature to a programmed set point and cycling precisely 
maintains that temperature rather than causing the temperature to 
oscillate between limits of a dead zone. Minimum pause and on-­
time intervals of the cycling mode are established in accordance 
with optimum thermal transfer efficienty and/or equipment 
limitations. The initial cycle pause interval is a function of 
the degree transition time (i.e., time required for system to 
change temperature one degree as measured during continuous on-­
time mode); the initial cycle on-time interval becomes the 
established minimum interval. Cycle intervals are modified as 
necessary to maintain the temperature at the set point with 
preference given to minimizing the cycle on-time interval. 
Hence, the cycle on-time interval is decreased to its established 
minimum before attempting to increase the cycle pause interval; 
conversely, the pause interval is decreased to its established 
minimum before increasing the cycle on-time interval. The system 
is predisposed to remain in the cycling mode whereby 
predetermined temperature variations from set point, in a 
direction opposed to system control, initiate a continuous on-­
time to bring the temperature back 
 
 
to set point, but only after attempting to do so with an 
additional modified cycle. Degree transition time and initial 
pause and on-time intervals are re-established during each 
continuous on-time mode. Cost savings are provided by cycling, as 
compared to continuous on-time, are periodically computed.

IPC: H03H11/48
Filed: 1988-06-16
Abstract: This reactance circuit comprises a differential 
amplification circuit formed by differentially connecting the 
first (1) and second (2) transistors to each other, a load (4) connected 
to a collector of the first transistor, a reactance element (5) 
interposed between a base of the first transistor and a 
reference potential point (A), and a capacitor (8) and a resistor (9). 
connected in series between the collector and the base of the 
first transistor. A negative feedback loop to the first 
transistor is formed by the capacitor and the resistor. 
Accordingly, when the collector of the first transistor is 
used as an output terminal, a negative equivalent reactance is 
produced in the output terminal.

voltage parameter, a high voltage parameter, and a parameter 
that deals with the rate of the voltage level change. The rate 
voltage level change includes a monotonocity function (Fig. 2).

Abstract: Tandem grooves (or other groove-like features) with controlled 
transition between the narrow and wide portion of the groove can be formed in a 
semiconductor surface, exemplary a (100) Si surface, by a method that comprises 
patterning a first masking layer such that the resulting aperture in the masking 
layer defines the tandem groove, re-covering the narrow part of the aperture with a 
second masking layer, subjecting the wide portion of the aperture to an initial 
etch, removing the second masking layer from the narrow part of the aperture, and 
subjecting the aperture to a further etch such that both the wide and the narrow 
portions of the tandem groove are completed. The inventive method is 
advantageously used to produce grooves that allow attachment of a coated optical

Title: Improved data consistency between cache memories and the main memory in a multi-processor computer system
IPC: G06F12/0817
Filed: 1989-09-28
Abstract: A method for insuring data consistency between a plurality of individual processor cache memories and the main memory in a multi-processor cache memories and the main memory in a multi-processor computer system is provided which is capable of (1) detecting when one of a set of predefined data inconsistency states occurs as a data transaction request is being processed, and (2) correcting the data inconsistency states so that the operation may be executed in a correct and consistent manner. I particular, the method is adapted to address two kinds of data inconsistency states: (1) A request for a operation from a system unit to main memory when the location to be written to is present in the cache of some processor unit-in such a case, data in the cache is "state" and the data inconsistency is avoided by preventing the associated processor from using the "stale" data; and (2) when a read operation is requested of main memory by a system unit and the location to be read may be written or has already been written in the cache of some processor - in this case, the data in main memory is "stale" and the data inconsistency is avoided by insuring that the data returned to the requesting unit is the updated data in the cache. The presence of one of the above-described data inconsistency states is detected in a SCU-based multi-processing system by providing the SCU with means for maintaining a copy of the cache directories for each of the processor caches. The SCU continually compares address data accompanying memory access requests with what is stored in the SCU cache directories in order to determine the presence of predefined conditions indicative of data inconsistencies, and subsequently executes corresponding predefined fix-up sequences.
