摘要:
The present invention relates to an apparatus for protecting a secondary battery by preventing overcharge of the secondary battery. The apparatus for protecting a secondary battery includes: a secondary battery; a power supply, connected with both electrode terminals of the secondary battery, for providing a charging voltage and a charging current to the secondary battery to charge the secondary battery; and a secondary battery protection unit for shorting the power supply thereby to stop charging the secondary battery if a charging voltage of the secondary battery is above a predetermined voltage.

A wafer transfer apparatus having two independently movable transfer modules. The apparatus that transfers the wafers from one chamber to another includes a first transfer module and a second transfer module. Each module has a robot arm and at least one blade. Each robot arm freely rotates along the chambers, and each blade is rotatably connected to the robot arm. The first and second transfer modules move independently in same or different directions. Each transfer module may have two blades, which are joined respectively to upper and lower parts of the robot arm. Furthermore, the first and second transfer modules can maintain an angle of at least one hundred twenty degrees, whereby preventing the wafers from being overlapped in transit.

A microwave oven with a toaster includes a toaster casing, a heating chamber inserted in the toaster casing, a bread receiver slidably inserted in the toaster casing, and a toaster door attached to a front side of the bread receiver. The bread receiver is selectively placed in the heating chamber. The microwave oven further includes a crumb tray slidably inserted in the toaster casing for collecting crumbs of bread and a holding unit for holding bread put in the bread receiver. The crumb tray is placed under the bread receiver. Further, there is provided a process for controlling a heater of the toaster, which is capable of properly baking bread even when the toaster is continually operated.

The present invention relates to an electroluminescent device, particularly to an organic electroluminescent device reliably receiving driving voltage from a voltage source, and a method of driving the same. A driving circuit of the electroluminescent device includes first to third sub-pixels formed on crossing areas of data lines and scan lines, a pre-charge driving circuit which applies pre-charge current to the data lines of the first to third sub-pixels and a data driving circuit which applies data current to the pre-charged data lines. The pre-charge current is applied to the first to third sub-pixels in different time. The organic electroluminescent device of the present invention and the method of driving the same can reliably receive the driving voltage from the voltage source, and prevent quick flames of the device.

A cogeneration system includes a compression air conditioner including a compressor, a first heat exchanger and a second heat exchanger; an absorption air conditioner including a regenerator, an absorber, a third heat exchanger and a fourth heat exchanger; a generator which generates electricity; a drive source which drives the generator to generate the electricity for operating the compression air conditioner and the absorption air conditioner and generates waste heat when driving the generator; and a waste heat recoverer which recovers the waste heat of the drive source and supplies the recovered waste heat to at least one of the compression air conditioner and the absorption air conditioner.
摘要:
A circuit for sensing an open-circuit lamp is provided. The circuit includes a reference voltage output unit, a voltage sensor, and a comparator. The reference voltage output unit provides a reference voltage. The voltage sensor detects a sensed voltage corresponding to a status of a lamp. The status of the lamp includes an open-circuit status and a closed-circuit status. The comparator compares the sensed voltage with the reference voltage and outputs a result indicating the status of the lamp.
