Abstract: Provided is a pill arrangement supply device which arranges and transfers pills for packaging a pill or testing the quality of a pill in a pill production line of a tablet or capsule medicine, etc., more particularly, to a pill arrangement supply device in which a pill seated in an arrangement groove of a roller is stably transferred without escaping from the arrangement groove. The pill arrangement supply device includes: multiple rollers which are sequentially arranged and have arrangement grooves to seat a pill on a surface thereof; a circulation member for circulating the rollers; a brush provided on the upper part of the roller and guiding a pill to an arrangement groove; and an inverse-rotating means provided at an arrangement section at which the brush is located, to cause the roller to rotate in a direction inverse to the direction in which the rollers circularly transfer.

Abstract: The present invention provides a method for purifying a large amount of human granulocyte-colony stimulating factors (hG-CSFs) from a recombinant E. coli with high yield and purity. According to the method of the present invention, human granulocyte-colony stimulating factor, identical to the native form expressed in the human body, can be easily purified with high yield and purity without an additional activation process. In particular, according to the purification method of the present invention, hG-CSF variants expressed in E. coli are efficiently removed to obtain physiologically active hG-CSFs with high purity.

Abstract: An X-ray imaging apparatus and a method of updating a pixel map correct a bad pixel of an X-ray transmission image. An X-ray transmission image is generated by detecting an X-ray penetrating an object, and it is determined whether a difference between a value of each one of the pixels forming the X-ray transmission image and a value of a nearby pixel adjacent to the each one of the pixels is equal to or greater than a reference value. A pixel having a value representing a difference equal to or greater than the reference value is determined as a candidate for a bad pixel. A message is displayed which requests a selection of whether to determine if the candidate is a bad pixel. The pixel map is updated by reflecting the determined bad pixel on the pixel map.

Abstract: Embodiments for testing an acoustic property of an ultrasound probe including a plurality of transducer elements are disclosed. A Schlieren image of an ultrasound probe and a visualized acoustic field of an ultrasound signal generated when one of the transducer elements is excited are acquired. A preprocessing including noise removal and position calibration upon the Schlieren image is then carried out. An acoustic property of the ultrasound probe is tested based on the preprocessed Schlieren image.

Abstract: A CAM device memory array having different types of memory cells is disclosed. A CAM device memory array is subdivided into at least two different portions, where each portion uses only one particular type of CAM cell, and each portion is dedicated to storing a particular type of data. In particular, at least one portion consists of binary CAM cells and the other portion consists of ternary CAM cells. The portions can be partitioned along the row, or matchline, direction or along the bitline direction. Since particular data formats only require predefined bit positions of a word of data to be ternary in value, the remaining binary bit positions can be stored in binary CAM cells. Therefore, the CAM device memory array will occupy an overall area that is less than memory arrays of the same density consisting exclusively of ternary CAM cells.

Abstract: A lighter that includes a hard-spring piezoelectric unit for preventing children from to operate lighter. A piezoelectric ignition unit has a plunger that is movable into a main casing to generate sparks for igniting a stream of flammable fuel. A hard-spring piezoelectric unit includes a plunger which includes auxiliary spring surrounding the plunger for increasing a force needed to actuate the piezoelectric unit and a blocking means for fixing the auxiliary spring with respect to the piezoelectric unit therefore enhancing an assembly efficiency of the gas lighter in manufacturing.

Abstract: A differential sensing amplifier for content addressable memory is disclosed. In the differential sensing amplifier there is a detection circuit for detecting at an input node a change in an input signal comprising, a differential amplifier having a sense node and a reference node, a means for alternating the differential amplifier between a precharge phase and a sense phase, a precharge means for providing an input signal precharge voltage to the input signal via an input device, said input device selectively coupling the sense node to the input signal upon a change in the input signal, and a reference means for providing the reference node with a reference signal that continuously tracks the input precharge voltage during the precharge phase and actively maintains the input signal precharge voltage during the sense phase.

Abstract: A lighter that includes a safety mechanism for preventing its ignition. A piezoelectric lighter ignition unit has a plunger that is movable into a main casting to generate sparks for igniting a stream of flammable gas. A safety mechanism includes a plunger which includes a notch at one side to define an open surface that extends transversely to the direction of motion of the plunger. A latch has a stop portion that makes contact with the transverse open surface to obstruct the motion of the plunger. An arm moves the latch.
