摘要： A readout circuit in magnetic recording device is disclosed, in which a test data signal for detecting an error in the characteristics of an automatic equalizer is recorded in a predetermined position of each track of a magnetic recording medium. In readout mode, a test data signal for a selected track is read out first, and this signal is compared with a reference signal dependent on the system conditions to determine an error from the reference signal. The optimum equalization coefficient is determined to eliminate this error from the reference signal and set in the equalizer. The data is readout under the optimum equalization characteristics thus set.

摘要： A circuit for detecting the variation of resistance of a variable-resistance element comprises a pair of grounded-base transistors with their base electrodes provided with different base voltages and with their emitter electrodes connected to both terminals of the variable-resistance element so that the voltage between both terminals of the element is kept constant. The current density of the variable-resistance element does not vary when the resistance of the variable-resistance element varies, whereby the lifetime of the element can be prolonged.

To prevent rotating stall, baffle vanes 5 capable of having their angles varied are installed upstream of the inlet guide vanes, actuators to vary the angles of baffle vanes are coupled to the baffle vanes, sensors installed upstream of the baffle vanes detect a rotating stall condition inside the flow passage of the compressor, and a control unit is responsive to signals from the sensors to output control signals to the actuators to vary the angles of the baffle vanes so as to prevent the rotating stall condition. Instead of the baffle vanes, fluid jets may be provided upstream of the inlet guide vanes for the same purposes.

The method has the step of forming, on a graphite substrate plate, an intermediate layer of rhenium by subjecting a metallic chloride to the thermal decomposition CVD process at a substrate temperature of 1200.degree. C. or more. The method further has the step of forming, on the intermediate layer, an X-ray generating layer of tungsten or tungsten-rhenium alloy by subjecting a metallic fluoride to the hydrogen reduction thermal CVD process.
