Title: Method of eliminating errors of discrimination due to intersymbol interference and a device for us9ng the method
IPC: H04B1/10
Filed: 1972-10-09
Abstract: 1410667 Digital transmission; error elimination HITACHI Ltd and NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP 9 Oct 1972 [8 Oct 1971] 46531/72 Heading H4P Faulty detection of a signal deformed by intersymbol interference is overcome by a double discrimination process. The received signal is first amplitude detected and the result compared with the received signal to show up any errors, these being themselves amplitude detected and added to the result of the first detection to make up a complete signal corresponding to the received signal. Referring to Figs. 1 and 4, an input signal a is sampled by clock pulses b in the primary discriminator 1 to give a discriminated waveform c. This is degraded by a circuit 2 simulating transmission system characteristics (examples, Figs. 7a-7k, not shown) to give a signal d of the same general quality as the received signal a, the latter also being delayed at 3 and compared with d at 4 to pick out any error, f. The error in this case has arisen from the failure of the clock pulse at t0 to detect an input pulse because of a noise depression on top of general lowering of signal level due to intersymbol interference. The secondary discriminator 11, clocked by pulses g, produces an output h which is added at 16 to a delayed version i of the first discriminator output c, thereby completing the discrimination of the input a by producing signal j. The signals h and f are also degraded and delayed respectively at 12, 13 and compared 14 to supply pulses to an error discrimination rate counter (not shown). In another embodiment (Fig. 8, not shown) a shift register 108 performing the same delay function as register 15 in Fig. 1, also supplies the degraded signal (d) in place of the circuit 2, by providing a plurality of different phase outputs through differently weighted resistors (104a to n). The analogue comparator 4 (108) and secondary discriminator 11 (109) may be implemented by various combinations of a differential amplifier and discriminators, with a full wave rectifier (Fig. 10, not shown), or with NAND gates (Figs. 11, 12, not shown). A plurality of second discriminator stages may be employed (Fig. 2, not shown).

Abstract: 1443963 High pressure compacting machine TOKYU SHARYO SEIZO KK 8 Oct 1973 [6 Oct 1972] 46955/73 Heading B1X [Also in Division B3] A machine for generating a shock wave by means of a supersonic projectile impacting a workpiece comprises a hydraulic chamber 4 into which a plunger 3 can be driven, a chamber 13 connected to the hydraulic chamber 4 and having a piston 15 and a barrel 23 whose bore is separated from the chamber 13 by a rupturable diaphragm. The piston 15 has two plungers 14, 16 extending with chambers 12, 18. The chamber 12 is in direct communication with the bore 6 df the hydraulic chamber 4 and the chamber 18 is filled with a light gas such as hydrogen or helium. The plunger 3 is integral with a hammer 2 which is raised by connecting the cylinder 1 to a vacuum source B. The stroke of the hammer 2 is effected by connecting the cylinder 1 to a compressed air source A causing the plunger 3 to enter the hydraulic chamber bore 6 which is filled with water or glycerine. The increase in pressure in the water or glycerine causes the piston 15 to move to compress the light gas in the chamber 18. The pressure rises until the diaphragm ruptures causing a projectile 21 to move at supersonic speed along the barrel 23. The barrel end is closed by a workpiece bolder 24 with a wonkpiece holding chamber 25 and a vent 26 leading to a vacuum source to evacuate the barrel. The workpiece may be a precompacted graphite block which is converted into diamond by the impact of the projectile. In a second embodiment, Fig. 2 (not shown), a second opposed plunger 55 of greater mass is used to compress the hydraulic fluid and reduce vibration of the machine.
