IPC: G01D9/00
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To reduce the effect of noises given to another measuring device by feeding a current having the reverse polarity to that of a burnout detecting current only immediately after the burnout detecting current is applied. SOLUTION: A burnout detecting current is fed to a thermocouple 2 from a recorder 1 at the time of burnout detection of the thermocouple 2. A switch SW2 is turned on to feed a current having the reverse polarity to that of the burnout detecting current from a reverse polarity current applying circuit 11 only immediately after the burnout detecting current is applied. The voltage applied to a temperature regulator 3 is lowered while the reverse polarity current flows, and the charges left on the temperature regulator 3 is quickly discharged. The error of the temperature regulator 3 can be reduced. When this measuring device and another measuring device are operated in parallel, the effect of noises given to another measuring device at the time of burnout detection can be reduced.

Title: Method and system for transfer of data
Inventor: ALLEN MICHAEL S
IPC: G06F15/177
Filed: 1993-12-20
Abstract: PURPOSE: To provide a method and system for improving the efficiency of data transfer of a data processing system. CONSTITUTION: Each of many processors 10 has an attached buffer for storing data transferred through a common bus 8. The common bus 8 connects the processors and memories to each other. Each processor 10 continuously monitors the common bus during a specific period after another processor tries to perform operation and can send a selected control signal when the tried operation nearly contravenes data coherence in the data processing system. When the control signal is sent onto the common bus, data transfer from the buffer to the processor is inhibited. When the control signal is not sent out onto the common bus, the data transfer from the buffer to the processor is allowed.
