Patent DE-3926656-A1 (DE)
Inventor: JEONG TAE-SUNG
IPC: G01K7/01
Filed: 1989-08-11
Abstract: A semiconductor temperature detecting circuit comprises a current supply means 10 and a polycrystalline silicon resistance means 20 interconnected in series between a first power supply line 11 and a second power supply line 12, and the terminal voltage Vo of the said polycrystalline silicon resistance means is outputted as the temperature detection signal. The device is most suitable for installation in ultra-high density semiconductor devices. Further, the device requires a low power consumption, and can be designed in a manner unrelated to the manufacturing process and variations of temperature. Further, the semiconductor temperature can be detected by a digital type method, and therefore, the detection signals can be directly used without going through any conversion or processing. By use of two different semiconductor devices and simple logic circuitry (Fig. 5 not shown), different logic outputs can be given for three temperature bands. The polycrystalline silicon may be doped or undoped. <IMAGE>

Title: Controlling RPM of brushless DC motor - with tachogenerator coupled rigidly with motor shaft, tachogenerator pulses are produced with sequential frequency twice number of poles of DC motor at least
Inventor: HEINZ RICHARD DIPL ING
IPC: H02P6/06
Filed: 1990-12-24
Abstract: Address signals concerning the actual motor phase relationship, are derived from the tacho pulse signals, by counting the tacho pulses with a forward/backward counter (6).

Address signals are derived from the tacho pulse signals and a timed reference signal, for determining an actual motor rpm with a counter (9). The address values of which as address part are called up for reading the data signals from the constant value storage. USE/ADVANTAGE - Method for controlling rpm of brushless DC motor.
