Abstract:
Disclosed are a (meth)acrylate compound, a photosensitive polymer, and a resist composition, and the (meth)acrylate compound includes a lactone-group-containing (meth)acrylate compound represented by the following Chemical Formula 1.
Abstract:
A probe for an ultrasound system, and a method of manufacturing the same are disclosed. The probe includes a backing layer, a piezoelectric member installed to the backing layer, and a unidirectional conduction part installed to at least one of the backing layer and the piezoelectric member. The probe is manufactured by connecting the piezoelectric member to the PCB via a unidirectional conduction part, instead of soldering which requires difficult and laborious operations, thereby facilitating manufacture of the probe while reducing an operation time in manufacture of the probe.
Abstract:
The present invention relates to a process for preparing Crystalline Form A of Lansoprazole. Specifically, the present invention relates to a process for preparing highly pure Crystalline Form A of Lansoprazole in a large scale without any additional conversion step, even by using ethanol in which Crystalline Form B is easily formed.
Abstract:
A transmission method using synchronous reverse links establishes synchronization by controlling transmission times of mobile stations according to synchronization control messages received through a control channel and then controlling the transmission times according to synchronization control bits received through a traffic channel.
Abstract:
A method for manufacturing a linear compressor which has a cylinder block with a compressing chamber and an inner core which has a plurality of electric steel plates disposed around the cylinder block. The method includes punching each of the electric steel plates, radially stacking such plates and welding them to the inner core. The inner core is inserted into a cast mold for casting the cylinder block. Molten metal is then poured into the cast mold and pressure is applied to the cast mold so that the molten material fills the spaces between the electric steel plates, thus making the inner core integral with the cylinder block.
Abstract:
A waste heat recovery device for a marine vessel is disclosed. According to the embodiments of the present invention, the waste heat recovery device for a marine vessel includes: a heat exchanger, which recovers heat from the exhaust fumes discharged from the engine, to heat a first refrigerant under uniform pressure; a turbine which is driven by adiabatically expanding the first refrigerant heated under uniform pressure; a condenser which condenses the adiabatically expanded first refrigerant; and a heat exchanging pump which compresses the condensed first refrigerant so as to re-circulate the compressed first refrigerant to the heat exchanger.
Abstract:
A composition for a hardmask including copolymer including repeating units represented by Chemical Formulae 1 and 2 and a solvent, a method of forming a pattern using the same, and a semiconductor integrated circuit device including a pattern formed using the method are provided.
Abstract:
A probe for an ultrasound system, and a method of manufacturing the same are disclosed. The probe includes a backing layer, an electrode part formed on the backing layer, and a piezoelectric member installed to the electrode part. The probe is manufactured by connecting the piezoelectric member to the PCB via a unidirectional conduction part, instead of soldering which requires difficult and laborious operations, thereby allowing easy connection therebetween while reducing an operation time for connection.
Abstract:
In one embodiment, a sample of chemical solution is provided. A first optical property of the sample is detected at a first wavelength and an expected optical property is predicted at a second wavelength, using the first optical property. A second optical property of the sample is detected at the second wavelength. The second optical property is compared with the expected optical property to measure a contamination level of a particular contaminant in the sample.
