This system contains all necessary control and data circuitry to interface with CRT, standard ASCII keyboard, matrix line printer, EPROM programmer, dual single side double density floppy disk drive, cassette tape recorder, etc.
Methods AEEG were recorded with a 8 channel magnetic tape recorder made in England Oxford Medilog 9200,and followed by off-line analysis and comparision with routine EEG.
This system consists of a tape recorder,an A/D converter and a 386 computer. It can sample the stress signal of a machine in situ and calculate the fatigue life of the machine with the sampling data. This system was used to predict the fatigue life of ZKX1848 oscillating screen,and the result agreed with the actual situation.
Using resistance strain gage, dynamic pressure sensor, slip ring and tape recorder, the blade vibration strain and exit pressure signals of rotor blades are recorded and then processed.
The system can work as an oscillograph,signal generator,FFT analyzer and digital tape recorder,which can be widely applied to the domain of aeronautics,astronautics,mechanics,civil engineering,vehicle,chemical industry,etc.
Changes were recorded with GF-777 tape recorder, then datas were input to DAB-1100 histogram processor to plot the histogram, at last the histogram was printed by Z3-304 function recording instrument.
After the analysis of the data exchange format of NC 401 numerical lathe, the access in computer by use of sound card instead of tape recorder is achieved, thereby the accessing speed and reliability of numerical program is increased very much,and the off line programming,debugging and simulation of the lathe are realized
Analogue tape recorders are usedas the traditional way tosupervise telephone communication but thismethod is neither convenient to query and replay,nor to store and manage tape recorder data.
Based on theanalysis of braking mechanism of A80 tape recorder and VPR-80 VTR,thisarticle approaches the mathematical relationship of each relative fact withthe braking force and the direction ratio,and deduces the relevant calculationformula. The example checking presents that this formula has a rather high-grade precision in calculation of this kind of mechanism,so it is of practicalvalue and steering significance to the productor designing and eguipmentmaintenance.
Each seismograph consists of three 2Hz seismometers of type LS-1, three amplifiers of type DDF-5, three modulators and one magnetic tape recorder of type DCJ-1, a quartz clock, a timing circuit and a radio.
The results indicate that this method can identify and forecast effectively the over - friction malfunction of flight data tape recorder by processing 312 sorties of flight data.
This experiment investigated the food intaking seduction function of different amino acid groups and their correlative compound laid in food package via recording amounts clarias lazera biting the food package by mechano-electrical transducer ,two-channel physiological recorder, frequency modulation chart recorder and translator, CS-1022 oscilloscope and GF-777 tape recorder.
Microtremor observations at 59 stations in the Akita plain in Japan were carried out during November 23 through November 28, 1969 using magnetic tape recorder.
An experimental situation is then treated; system-component models are developed for the digitizer, tape recorder, filter, transducer and mechanical structure.
The Interkosmos5 VLF experiment consisted of a spectrum analyser with twelve narrow-band channels and broadband measurements between0.07 and20 kHz using an analogue telemetry with a tape recorder on board.
