Consequently, a main thyristor current detours the m channel beneath a gate 140 and passes through the layers 114, 118 and 120 from the P region 116 thence flows upward through the device toward the N emitter 112. Subsequently, it passes through a p-channel MOSFET beneath a gate 138 and a P region 126 and flows toward a cathode 134. The p-channel MOSFET is connected in series with a thryistor and current saturation characteristics are provided by the MOSFET limiting saturation of the device through current.

Title: Temperature sensor
Inventor: SAGAWA MASATO
IPC: G01K7/36
Filed: 1978-12-26
Abstract: PURPOSE: To miniaturize a temperature sensor which converts temperature variation into an electric signal by passing magnetic flux through a converter at either a lower-temperature side or a higher-temperature side in comparison with a magnetic anisotropic varying temperature, and by providing a temperature/magnetic-field converter providing leakage at the other side.  
     CONSTITUTION: As for rare earth cobalt materials 1 and 2 varying in easy-to- magnetize direction with temperature, the C-axial direction of material 1 perpendicular to a paper surface and that of material 2 is in parallel to the paper surface. At a temperature where base surfaces perpendicular to axis C of materials 1 and 2 agree with easy-to-magnetize directions, magnetic flux between the N pole and S pole of permanent magnet 4 constitutes a closed loop passing through soft magnetic material 3 and material 1, and never leaks out of temperature/magnetic-field converter 10. When the C axis agrees with the easy-to-magnetize direction, on the other hand, material 1 disallows the magnetic flux to pass through and the magnetic flux flows out of material 2. For the purpose, a Hall element is arranged where this leaking magnetic flux can be detected, so that the temperature can be detected by the flowing and cutting-off of a current.
