Abstract: An objective of the present invention is to provide a steel sheet having a high strength which can provide excellent appearance quality. The steel sheet has a chemical composition including, in mass %, C: more than 0.030% to 0.145%, Si: 0% to 0.500%, Mn: 0.50% to 2.50%, P: 0% to 0.100%, S: 0% to 0.020%, Al: 0% to 1.000% or less, N: 0% to 0.0100%, and the like, wherein a metal micro-structures consisting of 70 to 95% of ferrite in volume fraction and 5 to 30% of hard phases in volume fraction, and a value X1 obtained by dividing a standard deviation of average Mn concentrations in a rolling direction at ¼ sheet-thickness positions in a sheet thickness direction by an average Mn concentration at the ¼ sheet-thickness positions is 0.025 or less.

Abstract: A network of a new configuration is flexibly constructed while maintaining a stable operation in the network. A management device includes: a detection unit that detects addition of a function unit to a network including one or a plurality of on-vehicle function units; an acquisition unit that acquires function unit information of a new function unit that is the function unit the addition of which has been detected by the detection unit and function unit information of each on-vehicle function unit, each piece of function unit information including information regarding network configuration of a layer lower than an application layer; and a generation unit that, based on the pieces of function unit information acquired by the acquisition unit, generates configuration information of a new network that is the network further including the new function unit.

Abstract: A control device controls driving of a pulse motor to cause liquid that is sucked into a syringe in a single suction process to be discharged over a plurality of discharge processes. The control method of the control device is a method that controls driving of the pulse motor so that rotation of a ball screw for executing each discharge process starts from an identical rotational angle position relative to a slit of a coupling.

Abstract: Disclosed is a keyword extraction apparatus and method capable of overcoming a problem in the conventional automatic keyword extraction wherein character strings in a sentence to be processed are employed, as they are, to assign a document with an index in terms of keywords; hence words having the similar meaning but different expressions in written language cannot be retrieved. The keyword extraction apparatus comprises technical term storage means for storing technical terms with proper expressions and different expressions thereof, and basic word storage means for storing general basic words of high frequency. Technical-term segmentation point setting means cuts out a range of any of the technical terms stored in technical term storage means from an input sentence. When the cut-out technical term is written in a different expression, the different expression is replaced by a corresponding proper expression in proper expression replacing means.
