Abstract: A lab-on-chip substrate includes a resin having a silicon content of 10% or less by weight as its base material and a hydrophilic polymer covalently bound onto the surface thereof by high-energy ray irradiation suitable for a protein-processing chip. The lab-on-chip substrate is resistant to washing and usable for an extended period of time without adsorption of proteins on the base material surface, i.e., a protein electrophoretic polymeric chip having a microchannel allowing high-accuracy analysis of trace amounts of proteins because of reduction in the amount of detection noise.

Abstract: In a test mode, a comparator compares for each column a value of data read from each memory cell connected to an activated word line with an expected value to be read from each memory cell. An error register holds error data based on a comparison result by a comparator. Each bit of the error data indicates the comparison result by the comparator for a corresponding column. Each bit is set to “0” when the comparison result for the corresponding column always indicates equality whichever word line is activated, and is set to “1” when once the comparison result for the corresponding column indicates difference.

The moving blades of a rotor included in a steam turbine vibrate as the rotor rotates, inducing an excessive stress in joints of connecting members for connecting the adjacent moving blades and blade portions of the moving blades and damaging the joints. It is a task of the invention to prevent moving blades from being damaged due to vibration.
