Title: Multi-processor system
Inventor: KUWAKI KATSUHIKO
IPC: G06F15/16
Filed: 1989-11-21
Abstract: PURPOSE:To allow other processor processing to synchronize with a reset operation of each processor by executing quickly the own reset processing, when a reset request is generated, and also, making a communication inhibiting signal significant until the initialization processing is ended, when the reset is started. CONSTITUTION:A communication inhibiting signal on inhibiting signal lines 11-13 is monitored by an inhibiting signal monitoring means 8 provided in the inside of each processor 1-3, and based on a result of this monitoring, whether a communication is possible or not is informed to a transmitting/receiving means 5, and when the communication is possible, data is exchanged mutually through a data bus 4. In this case, when a reset request is generated in a processor 2, an internal reset means 6 is actuated, and a built-in inhibiting signal generating means 7 makes a communication inhibiting signal sent out to the inhibiting signal line 12 significant simultaneously with a start of the reset processing. In such a way, the processor 1 waits for the data transmission/ reception to the processor 2 until the communication inhibiting signal becomes insignificant, or suspends it and executes it in the next change.

Title: Combustion type heater
Inventor: INOUE TAKASHI
IPC: F23D11/44
Filed: 1994-11-11
Abstract: PURPOSE: To obtain a combustion type heater that can improve exhaust emission remarkably at the time of the stop of combustion, by a method wherein when a burners is stopped, the fuel and air feed rates are respectively reduced to specified feed rates and those feed rates are kept for a specified period of time after the burner is stopped, and when the specified period of time has elapsed, fuel feed is stopped, and the air feed rate just before the stoppage is kept for a specified period of time. CONSTITUTION: When receiving a combustion stop signal, a controller 6 reduces the fuel feed rate to Qf and the air feed rate to Qa to keep a proper A/F ratio and maintains those feed rates for a period of time T1. Thereby, the fuel feed rate to vaporizing members 31 and 32 is reduced and the remaining amount of fuel in the vaporizing members 31 and 32 at the time of the succeeding stop of fuel feed can be reduced. The fuel feed is stopped when a period of time T1 elapses, and on the other hand, the reduced air feed rate Qa is kept for a period of time T2 thereafter. As air is supplied and mixed at the reduced feed rate Qa, combustion of residual fuel continues without a considerable fluctuation in A/F ratio.
