Abstract: There is provided a non-oriented electrical steel sheet in which, in a cross section of a base material in a sheet thickness direction, the number density N2-5 of precipitates with an equivalent circle diameter of 50 to 500 nm present in a range of 2.0 to 5.0 ?m from the surface of the base material in the sheet thickness direction is 0.30 pieces/?m2 or less, and the relationship between the number density N2-5 and the number density N0-2 of precipitates with an equivalent circle diameter of 50 to 500 nm present in a range from the surface of the base material to 2.0 ?m satisfies Formula (1): (N2-5)/(N0-2)?0.5??Formula (1).

Abstract: A constitutive device quality determination server is communicably connected to an inspection device via the internet, the inspection device performing an inspection on a constitutive device configuring a board work machine by operating the constitutive device in accordance with to a type of the inspection, and includes an inspection data acquisition section that designates a predetermined type of the inspection for the inspection device and acquires inspection data obtained by the inspection by the inspection device, a determination section that determines quality of the constitutive device based on the acquired inspection data, and a transmission section that transmits a quality determination result determined by the determination section to a terminal device communicably connected over the internet.

Abstract: A process for producing carbamic acid esters (N-phenyl carbamate) which comprises reacting an amino group-containing compound (aniline), oxygen, a nitro group-containing compound (nitrobenzene), a carbon monoxide-containing gas and a hydroxyl group-containing organic compound (ethyl alcohol) in the presence of a compound of a transition metal belonging to Pt group of VIII group (Pd) of the Periodic Table as catalyst, a non-metal halide (HCl) and water.

Abstract: A video cassette recorder for rental use having a timer means for counting the preset time, a back up power-supply such as battery and so on, and a start means for starting said timer means whereby the recorder makes only the normal reproducing operation impossible to perform till the re-start is performed after the lapse of the preset time from the timer start.
