Provided are a delay locked loop (DLL) that may can be included in a data processing device and may include a duty correction circuit, and a duty correction method of such a DLL. The duty correction method includes aligning a second transition of an output clock at a first transition of a clock for duty correction, sampling the clock for duty correction at the first transition of the output clock to detect an error of a duty cycle, and performing duty correction using a skewed gate chain according to the detected error of a duty cycle.

A delay locked loop controls a plurality of delay blocks included in a delay line and thus generate a plurality of clock signals which have a frequency obtained by multiplying a frequency of a reference clock signal, an accurate phase delay, and a constant duty cycle. The delay locked loop calculates an initial delay value and applies it to the delay blocks, thereby preventing harmonic locking and reducing locking time.

Liquid detection sensors are attached to both sides of a robotic arm end effector of a semiconductor wafer process system. The sensor mechanism or probe is situated on the front side and backside of the end effector, designed with electrical lines that are traced onto a polyester base material. The electrical lines are positioned in a serpentine formation. The high conductance of the sulfuric acid in the copper sulfate solution acts as the conductor between the traced lines. When the conductive liquid comes in contact with the traced lines, the lines short and the sensor activates or turns on.

Disclosed is a stock account/order/market price inquiry service method using a mobile terminal that is able to perform a stock account/order/market price inquiry service through a mobile terminal using a stock chip. A stock account/order/market price inquiry service method comprising the steps of: (1) displaying a lower menu page on a mobile terminal of the stock account/order service after a PIN authentication; (2) generating an account/order service request message on the basis of stock chip information read from a stock chip and service request information corresponding to the lower menu and then transmitting the same to a relay server; and (3) receiving a service response message corresponding to service request message from the relay server and displaying the same on the screen of a mobile terminal.

Disclosed is a portable terminal using a flexible material. The portable terminal includes an upper portion, a lower portion and a flexible portion integrally connecting the upper and lower portions. The portable terminal is of a slide-type in which after the upper portion is bent about the flexible portion, the upper portion is slid in the lengthwise direction of the lower portion to open/close a predetermined area of the lower portion.

A cash transaction machine includes a storage for storing paper media, a first transfer element transferring the paper media sheet by sheet from the storage, a temporary stack part located at an end portion of the first transfer element in order to stack the transferred paper media and vertically transfer a stack of the paper media, a second transfer element including an upper transfer part and a lower transfer part for transferring the stack of paper media, a rejecting element including a moving cover sliding right and left in an entry space provided at the lower transfer part, and a withdrawal extension part formed corresponding to the end portion structures of the second transfer element and the rejecting element and installed at the end portion to provide an extension path connected to the transfer path. Also, the end portion structure of the second transfer element may be identical with the end portion structure of the withdrawal extension part, thereby simply installing the withdrawal extension part at the front or the rear surfaces of the withdrawal apparatus.

Disclosed is a currency note feeding apparatus for a currency note handling machine capable of stably feeding currency note by use of a single belt guiding upper and lower surfaces of the currency note, and driving upper and lower belts of the single belt by use of one motor. The currency note feeding apparatus includes a currency note feeding belt including an upper feeding belt coupled to a drive pulley of the upper feeding belt and a following pulley of the upper feeding belt for guiding an upper center of the currency note, and a lower feeding belt coupled to a drive pulley of the lower feeding belt and a following pulley of the lower feeding belt for guiding a lower center of the currency note, a drive unit coupled to a drive shaft of a drive motor for transferring driving of the motor to the drive pulley of the upper feeding belt and the drive pulley of the lower feeding belt, and a currency note feeding guide installed to both sides of the currency note feeding belt and contacting with upper and lower surfaces of the currency note which is not contacted with the currency note feeding belt to guide feeding of the currency note. The currency note feeding apparatus reduces costs of manufacturing the machine, and the feeding speed of the belt is easily controlled.
