Patent EP-0222074-A2 (EP)
Inventor: MALMQUIST CARL ALBERT
IPC: G06F13/364
Filed: 1986-08-12
Abstract: An arbitration apparatus for use within a computer system comprises a plurality of individual arbiters (10i1, 10i2) arranged in a particular configuration wherein the individual arbiters are located according to their relative priority. Each arbiter has a request terminal (REQ) for receiving access request signals, requesting access to a shared system bus, and an enable terminal for receiving an enabling signal. The enabling signal is generated if access requests are not received by higher arbiters in the particular configuration relative to the specific arbiter. If an arbiter is energized by coincidence of an access request signal and an enabling signal, an access grant signal is developed. If more than one access request signal energizes the arbiter at the same time, a command rotor (10i1b, 10i3b), connected to the arbiter, determines the priority of access of the request signals to the shared bus in response to the "rotation" of the command rotor. If the access request signal is of a predetermined type, a pre-emptive grant signal may be developed from its arbiter even in the absence of an access request if there are no higher requests and no lower grants. If a refresh request is received by an arbiter when its enabling signal is not received, the refresh request is latched, and a refresh takes place when the enabling signal is finally generated.

Abstract: To render possible a complex influence on the adjustment characteristic of a device for varying the angular relationship of two rotationally coupled elements depending on the rotational speed, the spring mechanisms of the centrifugal force measuring mechanism used for adjusting the two elements are designed with at least three concentric helical compression springs, at least two of which act on a moving spring plate clamped between them. As the speed increases, the moving spring plate is moved along against the influence of the second spring, by the flyweight, after an initial movement of the flyweight which acts solely against the influence of a first spring, the third spring being destressed and a further point of inflection occurring in the overall characteristic once it is completely destressed. By the arrangement of additional springs, acting on the moving spring plate in different speed ranges, further points of inflection of the overall characteristic can be achieved in the adjustment range and the gradients of the overall characteristic in the region between the points of inflection can be varied as required. <IMAGE>

Abstract: Disclosed is a self-excited alternator of the brushless type, having a rotating field which is excited by an alternating current exciter whose rotating armature is mounted to rotate with the rotating field winding of the alternator and is permanently connected to the field winding of the alternator via field rectifier means also mounted to rotate with the field winding. The exciter has an exciter stator primary winding (FX) and a rotary exciter secondary winding (U) connected via rotary field rectifier (D1) means to the rotary main field winding (FM) of the alternator. The primary excitation direct current for the exciter is derived, via magnetic coupling, from a rotary auxiliary magnetic field produced by a feedback winding (FF) connected in series with the main field winding and mounted to rotate herewith. A common magnetic circuit is used for coupling the rotary feedback winding with a auxiliary stator secon­dary winding and for coupling the exciter primary and se­condary windings. The common magnetic circuit comprises a common stator core on which the exciter primary winding (FX) and the auxiliary secondary winding (V) are provided and a common rotor core on which the exciter secondary winding (U) and the feedback winding (FF) are provided. The rotor core is so shaped and the feedback winding is so provided thereon that in operation a pole group having either K or NK feed­back pole pairs is formed with poles uniformly disposed around the rotor core. The stator core is so shaped and the exciter winding or windings are so provided thereon that in operation a pole group having either NK or K exci­ter pole pairs are formed with poles uniformly disposed around the stator core, the ratio of feedback pole pairs to exciter pole pairs being either K to NK or NK to K, where K is any number and N is an even number. Either the feed­  back winding or the exciter primary winding, as the case may be, for forming the pole group having K pole pairs com­prise one or more first winding portions wound for gene­rating the poles of that group whereby, with rotation of the rotor core relative to the stator core, the nett change of magnetic flux linking with each first winding portion and due to the pole group having NK pole pairs is substan­tially zero.

Abstract: An automatic article stacking system wherein a plurality of articles (11,12) to be stacked are arranged in layers prior to being stacked. The layers are advantageously arranged horizontally orthogonal to one another so as to enhance the stability of the stack. A measurement system (17) is provided for determining whether any of the articles exceeds a predetermined size limit. In one embodiment which is arranged for stacking egg cartons, a determination that the egg carton exceeds the predetermined size limit signifies that the egg carton is open and, therefore, not in a form suitable for stacking. The open egg carton is conveyed under an elevator (20) which accumulates the articles to be stacked, and to a discharge area (60). Thus, closed egg cartons are accumulated in layers and stacked. Successive layers of articles are stacked under prior stacked layers.

Abstract: In a semiconductor memory device such as an E 2 PROM, or a NOVRAM a write enable signal (WE) is supplied to a buffer formed by an enhancement-type transistor (Q11) and a depletion-type transistor (Q 12 ) having a node (N 3 ). The potential at this node is applied to a set terminal of a flip-flop (FF), and only when the potential at the node is higher than a trip point of the flip-flop, is the flip-flop set to generate an internal write enable signal (IWE) for an actual write operation. This prevents spurious signals occurring during powering up and powering down of the memory device.

Abstract: The invention relates to a ball-tube mill with at least two chambers (7, 19), which are preferably arranged on a common shaft (5) and of which at least one contains solid grinding balls (2) of steel which roll on the rotatable inner wall (4) of the chamber (19), the material to be ground being fed through a charging opening (6) of the first chamber (7) and passing from the latter after appropriate crushing into the chamber (19) following in the direction of the flow of material. The grinding chamber (7) that is first in the direction of the flow of material is constructed as an antechamber which contains at least one circular ring (8) or circular disc of steel as grinding body, whose external diameter (a) is less than the inside diameter (b) of the inner cladding (10) of the grinding chamber (7) and corresponds at least to a quarter to half of the inside diameter (b) of the inner cladding (10) of the grinding chamber (7), and which is guided in a groove (9), extending in the circumferential direction, of the inner cladding (10) of the grinding chamber (7). The external diameter (a) of the ring (8) or the disc is preferably approximately 25% smaller than the diameter of the base (11) of the groove of the inner cladding (10). Because of the large external diameter (a) of the disc or the ring (8), material of very large grain size is drawn in between the running surface (12) of the ring (8) or the disc and the base (11) of the groove, and because of the great weight of the ring (8) or the disc material is crushed by pressure between the running surface (12) of the ring (8) or disc and the base (11) of the groove.

Abstract: A self-aligned gate (SAG) transistor or FET is described which transistor overcomes several disadvantages of the prior art for making SAG field-effect transistors. The disadvantages noted above result from the fact that current SAG FET's have a symmetrical structure, with n+ regions on either side of the gate electrode. This invention provides a means of masking off a region on the drain side of the gate electrode before performing an n+ implant, so that the n+ implanted region is asymmetrical on the two sides of the gate electrode. This has the desired beneficial effect of reducing the parasitic source resistance, without the deleterious effects on gate-drain breakdown voltage, gate-drain capacitance, and output resistance that invariably accompany a high doping level on the drain side of the gate. Using this technique, substantially increased performance can be obtain from a self-aligned FET.
