摘要:
The inventive indene derivatives of formula (I) are capable of selectively modulating the activities of peroxisome proliferator activated receptors (PPARs), causing no adverse side effects, and thus, they are useful for the treatment and prevention of disorders modulated by PPARs, i.e., metabolic syndromes such as diabetes, obesity, arteriosclerosis, hyperlipidemia, hyperinsulinism and hypertension, inflammatory diseases such as osteoporosis, liver cirrhosis and asthma, and cancer.

Disclosed is a method for forming a micro pattern. After a dual photoresist film having different glass transition temperatures is coated, an exposure process and a wet development process are implemented to form a dual photoresist film pattern. A RFP is then implemented for the dual photoresist film pattern. Therefore, it is possible to prohibit warpage of the photoresist film pattern. Accordingly, the uniformity of the critical dimension and a pattern shape could be improved. A good uniformity of the critical dimension and a good pattern shape in the etch process could be thus implemented.

A pyrazole-3-one derivative of formula 1 or a non-toxic salt thereof, a preparation method thereof, and a pharmaceutical composition containing the derivative or the salt as an active ingredient are provided: wherein: R1 and R2 each independently represent C1-C3 alkyl, aryl, or substituted aryl; R3 represents amino or methyl; R4 and R5 each independently represent hydrogen, C1-C3 alkyl, halogen, methyl substituted with halogen, C1-C3 alkoxy, cyano, or nitro; or a non-toxic salt thereof.
摘要:
The present invention relates to a novel 3,4-dihydro-1H-naphthalene derivative having a structure of formula 1 or formula 2, its pharmaceutically acceptable salts and their geometric isomers as a highly selective cyclooxygenase-2 inhibitor. Wherein, R1, R2, X, A and Q are defined in this specification respectively.
摘要:
The present invention relates to a low-power and high-speed transmission and reception apparatus which reduces consumption power of a sending-end circuit by increasing a value of a termination resistor included in a sending-end circuit and a receiving-end circuit so that the value is greater than a characteristic impedance value of a transmission line.
摘要:
Provided is a forced evaporative humidifier using nano-vapor, which includes: a housing having an exhaust port formed in an upper surface thereof and a suction port formed at one side of a front surface thereof; a water tank located below the suction port to store water; an injection unit having an injection nozzle located above the suction port, a pump for pulling up the water in the water tank to the injection nozzle, and a transfer tube for transferring the water pulled by the pump; a blowing fan located above the injection nozzle to carry air toward the exhaust port of the housing; a humidifying unit located below the injection nozzle so that films, each having a body surface formed to allow the water injected from the injection nozzle to flow and a plurality of tube-type spacers protruding on the body surface, are stacked in a lateral direction therein; and an eliminator located between the blowing fan and the injection nozzle to prevent water drops included in a humid air humidified by the humidifying unit from being scattered.
