Title: Data saving system
Inventor: MORI TSUYOSHI
IPC: G06F11/14
Filed: 1987-12-19
Abstract: PURPOSE:To realize the reproduction of data at occurrence of an error, etc., with no use of a save buffer and to simplify the circuit constitution by storing the data read out of a storage device into a 1st and 2nd storage means when a 1st or 2nd arithmetic means is used for execution of the arithmetic operations. CONSTITUTION:A control means 5 controls 1st and 2nd storage means 1 and 2 and 1st and 2nd arithmetic means 3 and 4 to calculate and store the data in a storage device. At the same time, the means 5 performs the control to store the data read out of the storage device into both means 1 and 2 so that the arithmetic operations are carried out by the means 3 or 4. Thus the unexecuted data can be reproduced with use of the data stored in one of both means 1 and 2 that performs no arithmetic operation even in such a case where an arithmetic operation has an error and the original data is lost. As a result, the arithmetic data can be stored with no use of a save buffer and the second arithmetic operation is possible without complicating the circuit constitution for increasing the circuits.

Title: Hot water supply device
Inventor: TANAKA YOSHIHIKO
IPC: F23N5/24
Filed: 1993-11-26
Abstract: PURPOSE:To prevent the generation of noise from a fan when switching an ignition rotation over to a post purge rotation by performing post air purge with a smaller air volume than usually required when the amount of water of a burner is less than its lowest working volume, and which exceeds the lowest working water volume. CONSTITUTION:When a hot water supply faucet 16 is opened, a fan 18 is rotated to ignite with a controller 30 so that a burner 17 is burnt. Therefore, water from a water inlet pipe 11 is heated at a heat exchanger 10 and supplied to a hot water supply pipe 12. The hot water is mixed with water from a bypass pipe 13 at a mixing controller 14 and supplied from a hot water supply pipe 15 as hot water whose temperature is controlled so as to reach a setting hot water supply temperature. When a heat exchanger flow rate sensor 21 detects that the water is less than a minimum amount of working water for burner, a fan 18 supplies air to carry out post air purging. In this case, when it is detected that the water is less than a minimum amount of working water for burner, and the water exceeds a minimum amount of working water for mixing, the post purging operation is carried out with the amount of supply air lower than that of standard air purging.
