摘要:
A data storage device includes a central processing unit (CPU); a peripheral device; a power management unit (PMU) configured to control a power supply to the CPU and the peripheral device; and a receiver configured to transmit a second signal to the PMU through a second transmission path after transmitting a first signal to the CPU through a first transmission path, the receiver being configured such that the first and second signals transmitted by the receiver are signals that were output from a host.
摘要:
An apparatus for quickly determining a fault in an electric power system includes a current transformer, a current determination unit and a fault determination unit. The current transformer detects current supplied to the electric power system and outputs a current detection voltage. The current determination unit respectively compares the current detection voltage, the first-order differential voltage of the current detection voltage and the second-order differential voltage of the current detection voltage with predetermined first, second and third reference voltages. The fault determination unit determines whether a fault occurs based on the compared result of the current determination unit and generates a trip signal when it is determined that the fault has occurred.

Disclosed are a surface treatment system that includes a deposition chamber (100) for forming a deposition layer at a surface of an object of surface treatment (900); a carrier (910) for carrying the object of surface treatment (900) by mounting thereon, and a power applying unit (230) for forming a deposition reaction by applying a power to the object in the deposition chamber (100), wherein the power applying unit (230) includes a fixed power applying unit (220) installed in the deposition chamber (100) and connected to an external power source (210); and a movable power applying unit (230) installed at the carrier (910) for being electrically connected to the fixed power applying unit (220) movably as the carrier on which the object of surface treatment (900) is mounted goes into the deposition chamber and thereby applying a power to the object of surface treatment mounted on the carrier by contacting thereto.
摘要:
A spin scrubber apparatus has an index unit configured to support one or more cassettes, a processing unit having one or more cleaning stations facing the index unit across a transfer space, and a substrate transfer device disposed in the transfer space for transferring substrates one-by-one between the index unit and the processing unit. The transfer device includes a transfer block, and an index arm and a transfer arm unit supported by the transfer block. The transfer block is movable in the transfer space to position the index arm or the transfer arm unit in front of a cassette or a spin scrubber. The index arm loads/unloads substrates into/from a cassette mounted to the index unit. The transfer arm loads/unloads substrates into/from the processing unit. All of the movement takes place in the transfer space. Thus, the apparatus is compact, and it takes relatively little time to clean the substrates.
摘要:
A reaction gas supplying comprising an MFC and adapted to sense when there is an error in the MFC, and a related method are disclosed. The reaction gas supplying device comprises a gas supply line disposed between a process chamber and a gas supplying element, a mass flow controller adapted to control a supply amount and a supply time of a gas, and a digital pressure gauge adapted to measure the pressure of the gas. The device further comprises a database, and a controller adapted to generate and output a first flow rate control signal, compare the measured pressure value of the gas with a standard pressure value stored in the database corresponding to the first flow rate control signal, and output an alarm generation control signal when the measured pressure value of the gas is outside of a set error range around the standard pressure value.
摘要:
A surface treatment system in which gas for a deposition reaction is injected into a deposition chamber and power is applied to form a deposition reaction to form a deposition layer at a surface of an object or surface treatment, wherein the deposition chamber has a plurality of deposition spaces disposed in parallel and a convey unit for conveying one or more objects of surface treatment to each deposition space or discharging the objects of surface treatment from each deposition space after a deposition reaction.
