Title: Circuit for preventing process failure for ion injection equipment
Inventor: SHIN IN-DONG
IPC: H01L21/265
Filed: 1998-08-28
Abstract: PURPOSE: A circuit for preventing process failure for ion injection equipment is provided to prevent ion injection by detecting a problem like a vacuum leakage in order to prevent a process failure. CONSTITUTION: The circuit for preventing process failure for ion injection equipment includes a source portion(10), a beam line portion(20), an end station portion(30), a time delay unit(62) and an error signal generation unit. The source portion generates +ion in order to perform ion injection. The beam line portion moves the +ion generated at the source portion. The end station portion injects the +ion moved via the beam line portion into a wafer. The time delay unit starts operation in response to a low vacuum pumping starting signal for making the end station portion low vacuum, finish the operation in response to a ion injection starting signal, and generates an output signal when the ion injection starting signal is not input within a predetermined time. The error signal generation unit generates an error signal in response to the output signal of the time delay unit, and generates a hold signal in order to stop the ion injection operation.

Title: Battery charger
Inventor: OH BYEONG SEON
IPC: H02J7/14
Filed: 1998-09-07
Abstract: PURPOSE: A battery charger is provided to prevent a fire from breaking out caused by application of overload to a car battery and check whether a charge state of the car battery is a discharge state or a normal state. CONSTITUTION: A power, which is applied between an input terminal and an output terminal through the input terminal, is converted into a reference voltage to be inputted to an integrated circuit. A charge current flowing between the input terminal and the output terminal is converted into a voltage to be inputted to the integrated circuit. The integrated circuit compares the reference voltage and the converted voltage, and leaves the input terminal and the output terminal in a short state until the reference voltage is equal to the converted voltage. If the converted voltage is greater than the reference voltage, the integrated circuit makes the input terminal and the output terminal short.

CONSTITUTION: A hydrodynamic bearing which is relatively insensitive to changes in load and rotational speed, wherein the hydrodynamic bearing is useful in a spindle motor (14) The hydrodynamic bearing can also be used as a bearing cartridge or as the cartridge that may be incorporated into a spindle motor orthe like, where the bearing includes a shaft (75) and at least two independent bearings each comprising a thrust plate (90 and 92) supported on the shaft and a counter plate incorporated in a sleeve (72) which is capable of relative rotation around the shaft.

Abstract: PURPOSE: A self-checking device of a discharging light source system is provided to prevent the generation of a fire which can be generated by the heating of a magnetron by self-checking a discharging member of a resonant cavity, a metal net, and a magnetron. CONSTITUTION: A self-checking device of a discharging light source system comprises a resonant cavity(102), a discharging member(103), a light reflection plate(102b), a metal net(102c). A light amount detecting section(200) is installed in the vicinity of the resonant avity(102), and measures the amount of the light which is radiated form the metal net(102c). A signal processing section(201) processes the light signal which is detected from the light amount detecting section(200). A current detecting section(204) measures the current which is supplied to a magnetron(100). A microprocessor(203) determines the disorder of a device and generates a control signal for controlling an AC power source. A voltage intercepting section(206) supplies and intercepts a common AC power source according to the control of the microprocessor(203).
