Title: Memory arrangement control systems
IPC: G06F12/06
Filed: 1972-10-06
Abstract: 1411290 Memory control systems FUJITSU Ltd 6 Oct 1972 [6 Oct 1971] 46326/72 Heading G4A A memory control unit MCU (Fig. 1, 8A) for a plurality of address modules 0-7 each having four memory banks recodes address bits applied from data processing units so that for example four way addressing (i.e. addressing in which successive addresses are placed in successive banks of a module) may be selectively changed to eight way or sixteen way addressing, enabling respectively eight and sixteen successive addresses to be accessed simultaneously. As described in the embodiment of Fig. 1 each pair of modules is controlled by a memory control circuit MACO-MAC3. A register 9 holding a 20-bit address A 0 -A 19 , of which bits A 0 -A 2  represent the module and bits A 18 , A 19  the bank in the module, feeds bits A 0 -A 17  to translators 8a-8d (one for each memory control unit). Units 10a, 10b, in the translators also receive signals W 0 -W 3  representing the required mode of addressing, i.e. 4, 8, 16 or 32 way, to recode the bits to derive new address bits A 0 <SP>1</SP>-A 17 <SP>1</SP>, the bank number remaining unchanged. Bits A 0 <SP>1</SP>-A 2 <SP>1</SP> are compared with signals L 00 -L 31  representing the module addresses to derive a signal representing the new module, bits A 3 -A 17  being applied to the selected module. The translators each comprise two banks of pairs of AND gates (13 and 14, 15 and 16, 17 and 18; 19 and 20, 21 and 22, 23 and 24, Fig. 8B, not shown) one gate in each pair being connected to one of the signals A 0 , A 1 , A 2  and to one or more of the signals W 0 -W 3 , the other gate being connected to one of the signals A 15 , A 16 , A 17  and the remainder of the signals W 0 -W 3 . An OR gate (25-30) is connected to each pair of AND gates, the output bits A 0 <SP>1</SP>-A 2 <SP>1</SP> and A 15 <SP>1</SP>-A 17 <SP>1</SP> being taken from the OR gates. The comparator (Fig. 8C, not shown) comprises, for each of the two modules with which it is associated, gates to produce the inverse exclusive OR function on the bits A<SP>1</SP> 0 -A<SP>1</SP> 2  and the bits L representing the module with which it is associated. In the embodiment of Fig. 9 in which each module of the four banks is controlled by a separate memory address control circuit MAC0- MAC7, the bank addresses are each represented by five bits L 0 -L 4  (designating one of the thirty-two possible banks) and signals W 0 -W 7  specifying the required mode of address (1, 2, 4, 8 way) for the associated memory address control circuit. From these signals and signals representing the memory capacity, gating signals G2, G2 ... G8K are derived (Fig. 13, not shown). These signals are combined in bank select circuits (one for each bank) with the address bits A 0 -A 4 , A 16 -A 18  to select one of the banks. Bits A 2 -A 18  are also fed together with the signals W 0 -W 7  to gates 62-67, 101-103 to derive the modified address bits A 0 -A 13  for the selected bank.

Abstract: 1,189,680. Photo-electric vapour density measurement. AIR REDUCTION CO. Inc. Oct. 17, 1967 [Oct.31, 1966], No.47167/67. Heading G1A. The density of a vapour or a component of a vapour in a furnace for depositing vapour on a substrate is determined by ionizing the vapour and measuring the intensity of radiation subsequently emitted. In an electron beam furnace for evaporating metals, shown in Fig. 1, the vapour 15 is ionized by the heating electron beam generated at 42 and deflected by a magnetic field on to the metal 14 in a crucible. A photo-multiplier 26 receives via tube 53 radiation emitted by the vapour and at a frequency, characteristic of a particular element, selected by one of a number of filters mounted upon a disc driven by a programmer 84. The photo-electric signal indicative of the density of the particular element in the vapour operates a meter 70, such as a C.R.O., or a multi-channel recorder operated in synchronizm with the filters. The photo-electric signal may be compared with a reference voltage 74, the resulting error signal controlling the intensity of the electron beam to vary the density of the vapour. Different parts of the vapour can be examined by moving the light tube 53 with the aid of a ball and socket joint 90. A light trap 92 opposite the tube 53 avoids reflections off the wall of the furnace from reaching the photo-multiplier.

Abstract: 1,077,569. Automatic current control. SIEMENS A.G. Nov.18, 1965 [Dec.3, 1964], No.49118/65. Heading G3R. In a system for supplying several X-ray tubes such as X1, X2 and X3 in parallel from a single high-potential supply source T, G1, the control circuit for automatically regulating the tube current is arranged to operate at a safe low potential. Thus, the tube current of X1 is controlled by a circuit which includes the operating windings of a transductor TK1, a controller R1, a correcting member ST1 and the primary winding of a transformer HT1 having its secondary winding connected to the cathode heater of the tube, so that the heater current is correctively varied in dependence upon tube current variations as detected by the winding W1 of transductor TK1. The secondary winding of transformer HT1 and the winding W1 are at a high potential, and are suitably insulated from their associated magnetic cores which are earthed. The control circuit is thus isolated from those parts of the system which operate at high potential and which may be provided with an earthed shield. In modifications described in relation to Figs. 2, 3, 4 and 5 (not shown), the transductor TK1 is replaced by a current sensing circuit which includes a magnetorestrictive element, a diode, a triode, and a transistor respectively.
