Title: Deterioration detector for ultraviolet ray detection tube
Inventor: YAMADA TETSUYA
IPC: G01J1/00
Filed: 1986-12-19
Abstract: PURPOSE:To inform the replacement of an ultraviolet ray detector at an early stage and at a proper period, by monitoring the detection number of times of a flame during pre-purging and/or post-purging performed within a predetermined time. CONSTITUTION:A combustion control circuit 6 issues a blow control signal 6a to a fan 2a on the basis of the combustion start order of a controller 5 to enter pre-purging operation and the residual gas in a combustion chamber 2 is discharged. When a dummy flame is generated in said chamber 2, a discharge current is sent to a flame circuit 3 from an ultraviolet ray detector 1 and a flame detection pulse signal is outputted to a counter 4 and the controller 5 through lines 3a, 3b. At the time of the finish of pre-purging, the controller 5 compares count data 4a and the judge number-of-time data D of ROM 5b and, at the time of 4a>D, CPU 5a judges the deterioration of the detector 1 to inform the same to an operation part and stops the transfer to combustion sequence operation. When 4a<D and a detection pulse signal is outputted, it is judged that deterioration is not advanced to start usual combustion sequence operation.

Filed: 1999-10-22
Abstract: PROBLEM TO BE SOLVED: To shorten the time for restarting a signal link accommodation processor and to reduce the capacity of a memory to be used. SOLUTION: In an initial state, a caller side CSP1 requests a global translation to a data base processor 4, determines an outgoing side CSP2 on the basis of the acquired translated result and transfers the translated result and a received signal to the outgoing side CSP2.

In an ordinary state, the outgoing side CSP is retrieved/predicted from the first table 1 and the received signal is transferred. In the initial state, the outgoing side CSP2 registers the translated result transferred from the incoming side CSP1 in the second table and sends the received signal to a signal link #4.  In the ordinary state, the translated result is acquired from the second table on the basis of the received signal transferred from the incoming side CSP1, the outgoing side CSP is acquired on the basis of this translated result, and the received signal is sent to the signal link. When the prediction and acquisition of the CSP are different, the received signal is resent.
