Abstract: An operation condition storage stores information of operation conditions about an electronic device. A time information storage stores time information associated with the information of operation conditions. When the electronic device can be connected to the Internet, information stored in the operation condition storage and information stored in the time information storage may be regularly stored in an external server of the electronic device. A change input receives a change input for temporarily changing the information of operation conditions and receives change period information for specifying an applicable period of the changed information of operation conditions. These inputs are performed, for example, by operating, by a user, an input device (for example, a button or a touch panel) provided in the electronic device. A changer changes the time information using the changed information of operation conditions and the applicable period.

Abstract: A layered inductor is manufactured by layering “silver-based conductive layers” and “ferrite-based magnetic layers” and simultaneously firing these layers. The conductive layers are via-connected to form a helical coil. A shape of a cross sectional surface of the conductive layer, cut by a plane perpendicular to a longitudinal direction of each of the conductive layers is a substantial trapezoid shape, having an upper base and a lower base. A base angle ? of the trapezoid shape at both ends of the lower base is equal to or greater than 50° and is smaller than or equal to 80°.

Abstract: The invention relates to a coil-buried type inductor. The inductor comprises a conductive coil, a first fired ceramics body arranged at least in an area along an inner periphery of the coil, and a second fired ceramics body arranged so as to surround the entire of the coil along with the first fired ceramics body. The first fired ceramics body has porosity equal to or larger than 40 percent and smaller than 70 percent.

Abstract: A method for controlling the shrinkage of ceramic formed bodies is provided, including performing a preliminary test to determine an average shrinkage of ceramic formed bodies made from test lots of a ceramic powder, and determining a linear correlation between the average shrinkage and measured amounts of the ground test lots removed from a ball mill during a specific milling time interval. A batch of the ceramic powder is then ground, an amount of the ground ceramic powder removed from the ball mill during the specific time interval is measured, and the linear correlation is used to estimate the shrinkage of a ceramic body made therefrom. The difference between a target shrinkage and the estimated shrinkage is determined, and one or more of the processing conditions used to form the ceramic body are changed to offset the difference.
