Title: Circuit for preventing noise in car audio system
Inventor: KIM HYEON SU
IPC: G11B20/24
Filed: 1998-12-04
Abstract: PURPOSE: A preventing circuit of noise in a car audio system is provided to improve a tone quality of a car audio by removing an outer noise such as an engine noise flowed in the car audio through a driving switch of headlight when the driving switch connected with a driving switch of car audio in parallel is turned on. CONSTITUTION: A driving switch of headlight(40) and a driving switch of car audio(30) are turned on. A charging power of battery is fed to the car audio unit(20) after stabilizing through a coil(L1) and a condenser(C2) according as the driving switch of car audio(30) is operated. The battery power stabilized by the coil(L1) and the condenser(C2) is fed as a base driving signal of a second transistor(TR2) of a noise blocking circuit(50). Because the driving switch of headlight(40) is turned on, the second transistor of the noise blocking circuit(50) is turned on and a first transistor(TR1) is turned off. Because the first transistor of the noise blocking circuit is turned off through an outer noise such as an engine noise is flowed in through a driving line of headlight by turning on the driving switch of headlight(40), the noise is not flowed in the car audio unit(20) by passing diodes(D1)(D2). Therefore, the car audio unit(20) outputs an audio signal of fine quality without effecting from the outer noise signal when the driving switch of headlight(40) and the driving switch of car audio(30) are turned on.

Title: Method for deciding erosion form in lower unit of blast furnace
Inventor: KIM SEOK SSANG
IPC: C21B5/00
Filed: 1998-12-16
Abstract: PURPOSE: A method is provided to decide a change in the form of a lower unit in a furnace caused by the flowing passage of molten material and erosion. CONSTITUTION: Armometers are installed for calculating the exponent of ring shaped current by using the average temperature of a sidewall(21) and a floor(22) of a lower unit in a furnace. And, manganese is inserted for deciding the flow of the molten material and the liquid filtration of cokes(25) located in the lower unit of the furnace. Then, the flow of the molten material is measured for plural times. When, the exponent of the ring shaped current is over 1.0, which means the temperature of floor is lower than the sidewall, the erosion in the corner unit of the lower unit in the furnace is increased while lowering the erosion of the floor. Herein, the exponent of the ring shaped current is large, which means the molten material moves to a wire outlet(23D) while not penetrating the cokes.

Filed: 1997-04-21
Abstract: PURPOSE: Reproduction from the cased recording/reproduction-type optical disk(201) can be performed by using reproducing apparatuses capable of reproduction from reproduction-only-type optical disks. CONSTITUTION: A disk(1) is taken out from the case(2) before mounted in the reproduction-only-type apparatus(6). When the user takes out the disk(1) from the case(2), the opening/closing door does not open unless a protrusion of the identification section(3) is removed, so that a trace indicating that the disk(1) has previously been taken out is left in the identification section(3). Consequently, even though the disk(1) is returned to the case(2) as shown by the arrow D, the cartridge(4b) is different from the original cartridge(4) because historical information indicating that the disk(1) has previously been taken out is added to the identification section(3). In the recording/reproducing apparatus, when it is sensed based on the identification section(3) that the disk(1) has previously been taken out from the case(2), the contents are displayed. Then, in accordance with the user's direction, whether the information recorded just now is correctly recorded or not is verified. When it is determined that the information is not correctly recorded, the same information is recorded again.
