Title: Method of controlling rotational frequency of fan for stable ignition in suction state
Inventor: PARK JAE KYEONG
IPC: F24H1/00
Filed: 1998-11-17
Abstract: PURPOSE: A controlling method of the rotational frequency of a fan for stable ignition is provided to perform ignition easily even when a suction state occurs by controlling the rotational frequency of an exhaust fan properly after sensing the suction state when a suction state occurs in the initial ignition of a gas boiler. CONSTITUTION: A rotational frequency of an exhaust fan is sensed while the power supplied to the exhaust fan is cut off in the initialized state before the operation of a boiler. If the exhaust fan rotates, a suction state is decided, but if the exhaust fan does'n't rotate, a normal state is decided. If a suction state is not decided, the voltage for driving a fan is set up to igniting voltage after finishing free purge and a gas valve and an ignition plug are driven. Thereby an ignition stroke is performed. And if a suction state is decided, the fan driving voltage is set up to igniting voltage without regard to the rotational frequency of the exhaust fan after finishing free purge. Then the fan driving voltage is gradually reduced until the rotational frequency of the exhaust fan becomes the rotational frequency in the igniting step. Thereafter, the gas valve and the ignition plug are driven and the ignition stroke is performed.

Abstract: PURPOSE: A method is provided to distinguish a CD from a DVD promptly and reliably in an optical disk device by using the size of a zero cross period of a tracking error signal. CONSTITUTION: A reference time(Tr) is set by a zero cross average period generated from a tracking error. Herein, the tracking error is formed by crossing the tracks of each disk. When the disk is inserted, a pickup apparatus of an optical disk device is moved toward left and right for a certain number in a stopped state. A tracking error signal formed by crossing the tracks of the disk is sensed for a certain period. Zero cross period(T1-Tn) per tracking error signal is detected for calculating the average value(Tm) of the zero cross periods. The average value is compared to the reference time. The kind of the disk is decided according to the result of comparison.

Abstract: PURPOSE: A flash memory device is provided to promote pumping efficiency by shortening output lines of sector control circuit. CONSTITUTION: In a flash memory device, sector control block(11,12) is separated into left and right blocks to classify a cell array(13) into sector units. In addition, output lines(L11-L18) of respective sector control circuits in each sector control block(11,12) are divided into left and right blocks(15,16) and then connected to z-multiplex block(14). That is, the cell array(13) is classified by an output of the sector control block(11,12) transmitted through the divided output lines(L11-L18). Therefore, the output lines(L11-L18) is shortened by half. Moreover, a load capacitance is smaller and a coupling ratio is made better, so that a pumping efficiency is promoted.
