摘要:
A colonic drug delivery composition contains a first polysaccharide and a second polysaccharide wherein both polysaccharide are degradable by colonic enzymes and are mixed at a environmental pH of about 7 or above, without use of a cross-linking agent. A colon selective pharmaceutical composition and dosage form for oral delivery of a drug, diagnostic reagent, or mixture thereof includes the drug, diagnostic reagent, or mixture thereof in contact with the polysaccharide composition. A method of preparing such a colonic drug delivery composition and the colon selective pharmaceutical composition and dosage from are also disclosed.

A heat transfer pin of a heat exchanger, in which slits in the first row, slits in the second row, slits in the third row, and slits in the fourth row are arranged in parallel with an inflow direction of Pal air such that the interval between a virtual line crossing the centers of heat transfer pipes and the slit in the second or third row is larger than the interval between the slit in the first row and the slit in the second row or the interval between the slit in the third row and the slit in the fourth row, and is at least three times the width of each of the slits in the first to fourth rows, thus easily discharging condensed water formed on the heat transfer pipes to the outside and reducing resistance when the air flows. The slits in the first and second rows and the slits m the third and fourth rows, each having the shape of a parallelogram, are symmetrical with each other for the virtual line crossing the centers of the heat transfer pipes.

A converter device supplied with a drive power from an image forming apparatus instead of an external device and an image forming apparatus connected to the converter device. The converter device is provided between the image forming apparatus including a power supply port and a USB port and a host device including a parallel port such that data is transmitted and received between the image forming apparatus and the host device. The converter device is connected to the image forming apparatus through the power supply port and a power cable to be supplied with power. The converter device is operated with the supplied power to convert data output from the USB port into data capable of being input to the parallel port or convert data output from the parallel port into data capable of being input to the USB port.

A CMOS image sensor and a method of manufacturing the same are provided. The method is capable of reducing a distance between a micro-lens and a photodiode and simplifying the manufacturing process for the CMOS image sensor. In an embodiment, the interlayer dielectric layers of high level metal lines (e.g. third level and higher metal lines) can be selectively removed from the sensing section of a semiconductor substrate. The color filter layers and microlenses can be formed on the sensing section after the interlayer dielectric layers of the high level metal lines have been selectively removed.

An indoor unit for an air conditioner capable of performing cooling and heating, as well as ventilation functions as a single unit is provided. The indoor unit includes a main chassis, a ventilation port, a cross-flow fan, a side fan, and a ventilation duct. The main chassis is installed on a mounting portion and composing its exterior. The ventilation port formed to pass through the main chassis for inletting and exhausting air. The cross-flow fan is installed on one side of the main chassis to blow air in a direction perpendicular to its rotating shaft. The side fan is formed next to the cross-flow fan. The ventilation duct is connected to the ventilation port of the main chassis to ventilate the air forcibly blown by the side fan.

An indoor unit of an air conditioner capable of enhancing heat exchange efficiency and reducing noise/vibration is provided The indoor unit includes a main chassis, a front panel, a cross-flow fan, a fan motor, a heat exchanger, and a discharge port. The main chassis has a backside fixed on a place to be installed. The front panel is formed on the front of the main chassis and has a spacer formed in an inside thereof. The cross-flow fan is disposed in the inside of the space and provided in plurals on the same shaft. The fan motor provides rotational power to the cross-flow fan. The heat exchanger is formed on the front of the cross-flow fan with respect to the flowing direction of air. The discharge port guides discharge of the air blown from the cross-flow fan.
