Title: Combustion control device
Inventor: MATSUDA YUKIKAZU
IPC: F23N5/24
Filed: 1984-09-17
Abstract: PURPOSE:To prevent an abnormal stop and continue an operation in case of a power interruption within a specified period of time by a method wherein a back-up power supply for supplying a power supply to a micro-computer in case of the interruption of power, a circuit for detecting the interruption of power and an igniter for performing an electric discharging for a specified period of time are arranged. CONSTITUTION:When an interruption of power is generated, a burner motor 14 and a blower motor 5 continue to rotate for about 10 seconds and the pump circuit 17 terminated to supply kerosene with a delay of 10ms and then the combustion flame is diminished. In turn, an electrical potential in a bus line (c) is also decreased, a transistor 28c is turned OFF within several 10ms and 'H' signal is inputted to an input terminal K3 of a micro-computer 11. In case of momentary interruption of power within one second, the input terminal K3 is changed over to 'L' until the value of the third counter counts a value of 500 and then is changed over to (d). In the next step, an operation before the interruption of power is continued. Burner motor 14 and the blower motor 5 are reenergized while they continue to rotate under their inertia. The igniter 16 contains a function of a timer and when reenergization is to be performed, the timer is energized and an electrical charging is performed for a specified period of time, so that the ignition is carried again in simultaneous with a starting of operation of the pump circuit 17 and the subsequent combustion is continued.

Title: Read-out device for serial memory
Inventor: FUKUMURA KEIJI
IPC: G11C11/41
Filed: 1995-07-07
Abstract: PROBLEM TO BE SOLVED: To prevent an access time from lowering by ending pre-charge of a data line of an even number before a read-out circuit starts to operate at a read resetting. SOLUTION: A pre-charge circuit 16 is provided with the circuit pre-charging the data line DL1 connected to a read bit line group of the even numbered at the read resetting time. In the case that this circuit is not provided, when a memory cell of e.g. an even number address A is read out, an L level signal of a read resetting signal RRES* is received, the data line DL1 for the even number exists on a voltage value corresponding to the data in the memory cell of the address A, and is not pre-charged until the memory cell of 0 address selected after resetting is read out. Thus, by that the pre-charge circuit 16 pre-charges the data line DL1 connected to a bit line RBL0 for the 0 address at the resetting time, the delay of the access time and erroneous writing are prevented.
