Abstract: It is an object of the present invention to provide a rolled material, which is a material for high strength spring, and also can exhibit excellent corrosion fatigue properties after quenching and tempering even when suppressing the addition amount of an alloying element; and a wire for high strength spring obtained from such a rolled material. The rolled material for high strength spring of the present invention includes, in % by mass: C: 0.39 to 0.65%, Si: 1.5 to 2.5%, Mn: 0.15 to 1.2%, P: exceeding 0% and 0.015% or less, S: exceeding 0% and 0.015% or less, Al: 0.001 to 0.1%, Cu: 0.10 to 0.80%, Ni: 0.10 to 0.80%, and O: exceeding 0% and 0.0010% or less, with the balance being iron and inevitable impurities, wherein the number of oxide inclusions having an average diameter of 25 ?m or more is 30 or less per 100 g of a steel material, and an amount of nondiffusible hydrogen is 0.40 ppm by mass or less.

Abstract: An object of the present invention is to provide a rolled material for high strength spring, which has excellent wire drawability even when suppressing the addition amount of an alloying element, and which can exhibit corrosion fatigue properties after quenching and tempering. The present invention provides a rolled material for high strength spring, including C, Si, Mn, P, S, Al, Cu and Ni, wherein an amount of nondiffusible hydrogen is 0.40 ppm by mass or less, and an area ratio of ferrite expressed as a percentage satisfies an inequality expression (1) below, and a total area ratio of bainite and martensite is 2% or less: Ferrite area ratio<{(0.77?[C])/0.77?[C]/3+0.08}×100??(1) where [name of element] in the above inequality expression (1) means a content expressed in % by mass of each element.

Abstract: A voice recording and playback device of the present invention is capable of storage management of generated voice data, to which date information has been attached, as voice files, and comprises a display section capable of calendar display, and a control section for, at the time of retrieving voice files from a storage section, performing movable identification on a calendar display, as well as retrieving voice files that have been stored in the storage section based on date information attached to the files, and performing display of results of this retrieval indicating the existence of voice files close to day display on the calendar display, wherein the control section moves the identification position based on an instruction operation by the retrieval instructions section, and generates a notification in accordance with voice files that exist on the date of the identification position that has been moved.
