Abstract
Abstract A temperature measuring apparatus has temperature detecting means for detecting a temperature and producing a signal representative thereof, an A/D converter for converting the signal into a digital output signal, a memory for storing as temperature data the output signal of the A/D converter, read-out means for reading out corresponding temperature data from the memory and applying it to a processor, and wait means for setting a wait state by the read signal from the processor until the A/D conversion of the A/D converter is completed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
181 words
A temperature measuring apparatus comprising: a memory having a plurality of memory addresses storing contents corresponding, respectively, to a plurality of predetermined temperatures within a temperature measuring range of said measuring apparatus; temperature detecting means for detecting temperature and producing voltage signals representative thereof; an A/D converter for converting the voltage signals representing detected temperatures into digital signals having a form which corresponds to memory addresses in said memory; control means for operating said A/D converter to generate output digital signals respectively representing detected temperatures at predetermined time intervals and producing an output when the respective output digital signals have been generated at the predetermined time intervals; read-out means operated by a processor for reading out the contents of said memory in a temperature reading operation; and wait means connected to said processor for setting a wait state until receiving the output from said control means and delaying the temperature reading operation of said read-out means until after the conversion of the voltage signal into the output digital signal by said A/D converter has been completed at the predetermined time intervals.
Claim 2
Dependent Claim
181 words
