Title: Magnetic tape recording head heater - has power transistor used as both temp. sensor and heating element
Inventor: STARK REINHARD ING GRAD
IPC: G05D23/20
Filed: 1979-06-27
Abstract: The power transistor is used as both a temperature sensor and heating element to allow heating of the head of a magnetic tape reader, when the temperature falls below a predetermined value. The transistor (7) is located on the head having the base voltage (BE)proportional to the temperature. An operational amplifier (K) compares the measured value (UBE) with the reference (SO11) set by two resistors (R3,R4). When the measured value falls below the reference value, an astable multivibrator (M) is switched to cause the transistor to be gated so causing the temperature to increase.

Title: Magnetism detector employing electron spin polarisation - uses particle beam two-electron capture by charge separation of beam
Inventor: RAU CARL DIPL PHYS DR
IPC: G01R33/02
Filed: 1980-02-08
Abstract: The magnetism detector uses electron spin polarisation measurement via two electron capture from a body surface to a particle beam. The appts. is applicable to measurement of body surface magnetic characteristics, e.g. of ferromagnetics, magnetic alloys, catalysts etc. The measurements can be made simply and without application of an external magnetic field. Microscopic magnetic characteristics can be examined of microscopic bodies. Elimination of the need for an external magnetic field helps to eliminate stray field effects. The square of a magnetic parameter of the body is measured using the transfer of two electrons to a particle in the beam. The measurement involves determination of the particle beam current. The temp. dependency of the magnetic characteristic can be calibrated simply. The detector performs electrostatic charge separation and simultaneous beam component measurement.
