Abstract: A construction assisting system including a controller that performs construction assistance processing on the basis of positional relation between a worker and a hydraulic excavator, the construction assisting system including: an approach intention detecting device that detects an intention of the worker to approach the hydraulic excavator; an approach intention presenting device that presents a detection result of the approach intention detecting device to an operator of the hydraulic excavator; and an approach confirmation obtaining device that obtains a confirmation state of the operator of the hydraulic excavator for contents presented by the approach intention presenting device, the controller performing the construction assistance processing on the basis of position information of the worker when the operator of the hydraulic excavator denies the approach of the worker or when the operator of the hydraulic excavator does not confirm the intention of the worker to approach.

Abstract: The present invention relates to a continuous carbon fiber bundle that is easily divided by cutting to a length of 25.4 mm, a sheet molding compound (SMC), and a fiber-reinforced composite material to be molded using the same. The SMC includes carbon fiber bundles including carbon fibers with a single fiber fineness of 1.0 dtex or more and 2.4 dtex or less and a matrix resin composition. In the SMC, a mode value in a mass distribution of carbon fiber bundles with respect to a mass of individual carbon fibers bundle is 50% or less of the mass of the carbon fiber bundle with the largest mass, and additionally, a fiber-reinforced composite material molded using the same is used to address problems.

Abstract: There is provided a powder of a lithium transition-metal compound for a positive-electrode material in a lithium secondary battery, in which the use of the powder as that of a positive-electrode material in a lithium secondary battery achieves a good balance among improvement in battery performance, cost reduction, resistance to a higher voltage, and a higher level of safety. The powder of the lithium transition-metal compound for a positive-electrode material in a lithium secondary battery is characterized in that in a mercury intrusion curve obtained by mercury intrusion porosimetry, the amount of mercury intruded is in the range of 0.8 cm3/g to 3 cm3/g when the pressure is increased from 3.86 kPa to 413 MPa.

Abstract: To provide a green phosphor with high conversion efficiency of blue of near-ultraviolet light and excellent color purity, a multinary oxynitride phosphor represented by the general formula [I] is proposed. M1xBayM2zLuOvNw??[I] In the formula [I], M1 represents Cr, Mn, Fe, Ce, Pr, Nd, Sm, Eu, Tb, Dy, Ho, Er, Tm and Yb, M2 represents Sr, Ca, Mg and Zn, L represents metal elements belonging to the fourth group or the fourteenth group of the periodic table, and x, y, z, u, v and w are the numeric values in the following ranges: 0.00001?x?3 0?y?2.99999 2.6?x+y+z?3 0<u?11 6<v?25 0<w?17.

Abstract: An object of the present invention is to provide a high-efficiency red light emitting phosphor and white light emitting phosphor for using in a display or lighting which high-efficiently emits light in combination with a light source which emits light in the region from near-ultraviolet light to visible light. The present invention relates to a phosphor having a crystal phase having a specified chemical composition.
