Title: Temperature compensation in electronic apparatus
IPC: G05D23/19
Filed: 1972-09-01
Abstract: 1352659 Automatic temperature control HEWLETT-PACKARD CO 1 Sept 1972 [20 Oct 1971] 40586/72 Heading G3R A plurality of circuit units are provided with a temperature dependent drive current by a power supply controlled by the output of a temperature sensor. Current sensors are connected in series with the circuit units and provide thermal outputs which are averaged and detected by the temperature sensor. The latter also responds to changes in ambient temperature. As shown, a computer includes a number of magnetic memory core stacks 10 receiving drive current 13 from control elements 12. The current required by a given core stack is dependent on its temperature. Resistors 16 in series with the elements 12 act as thermal images of the core stacks 10 and are mounted on a board 19 positioned within the computer together with a thermistor 18 which senses the ambient temperature of the computer when the core stacks are not being supplied. A current of air is directed over the resistors 16 so as to convey heat from them to the thermistor 18 which thus responds to average changes in temperature of the resistors and controls power supply 14 accordingly through a servo-amplifier 20. The units 10 may also be disc or drum memory elements.
