Patent ES-373251-A1 (ES)
Title: Acceleration control of machines
IPC: H02P23/00
Filed: 1969-11-06
Abstract: In an acceleration or deceleration control circuit, the output from the collector of a transistor TR1, which, by reason of a differentiating circuit is made proportional to the acceleration or deceleration of a tachogenerator TG driven by an associated machine, is applied to transistors TR2, TR3, which each develop an output at its collector, a portion of the output from TR3 being fed back to TR1 via R2, C2, and R1 to increase the output of TR1. The time constant of C2 is longer than the time constant of any phase changing element in the circuit e.g. the solenoid of an electromagnetic clutch, such that for small variations in acceleration, the circuit has a rapid response, and for large variations the long term output of the circuit can adjust itself over a much wider range. The circuit may operate on an electromagnetic clutch or brake, via output terminals O1, O2.

Title: Plural virtual address space processing system
IPC: G06F9/46
Filed: 1977-06-06
Abstract: In a data processing system having a plurality of virtual address spaces, a virtual address is translated into a real address for accessing a main memory and the translation result is stored in a translation lookaside buffer, as in a processing system having a single virtual address space. Thereafter, in the case of the same virtual address as the above, the translation lookaside buffer is retrieved to translate the virtual address into a real address. Generally, even in the case of the same virtual addresses, if their virtual address spaces are different, the virtual addresses are translated into different real addresses. However, a control program, a control table or a common subroutine is provided in a common area in which the coordination of virtual and real addresses is always constant even in the case of different virtual address spaces. To enhance the efficiency of utilization of the translation lookaside buffer, common area indicating means is provided, by which the coordination of virtual and real addresses on the translation lookaside buffer is registered so that it can be used in common to a plurality of virtual address spaces.

T2 and rate FR3 such that fluid F circulates in the bed, of mass M2 and initial temp. T1, the bed temp. changes from T1 to T2 and the fluid temp. changes from T2 to T1. The fluid F leaves the bed zone used for the third stage. The temps. are regulated by regulating the flow rates and the mass of particles in the beds. The flow rate are given by FR1= T2 CPOS dt+DELTA H /t(CP2.T2-CP1.T1) FR2=A(1+A)j-2FR1 FR3=(1+A)j-1.FR1. Here CPS, CP2, CT1a are heat capacities of the particles, and of the fluids between 0 and T2 and O and T1, respectively, t=desired time for temp. to change from T1 and T2, DELTA H= heat of reaction.
