A coil-type electronic component has a coil inside or on the surface of its base material wherein the base material in the coil-type electronic component is constituted by a group of grains of a soft magnetic alloy containing iron, silicon and other element that oxidizes more easily than iron; the surface of each soft magnetic alloy grain has an oxide layer formed on its surface as a result of oxidization of the grain; this oxide layer contains the other element that oxidizes more easily than iron by a quantity larger than that in the soft magnetic alloy grain; and grains are bonded with one another via this oxide layer. The coil-type electronic component can be produced at low cost and combines high magnetic permeability with high saturation magnetic flux density.

A technology is provided for a viewer of broadcast information or recorded information to easily obtain information related to the broadcast information or recorded information from a server, in which, in a system in which a viewer apparatus and a content providing server for providing content information related to video or voice are connected via a network, the viewer apparatus obtains related information necessary for obtaining the content information; sends the related information to the content providing server so as to request the content providing server to send the content information; and obtains the content information sent from the content providing server.
摘要:
A radio communication receiving device performs prescribed operations upon detecting a frequency modulation preamble signal consisting of a series of alternating logical values. The device includes a low-pass filter that is connected to an output of a receiver that detects the frequency modulation signal and outputs an analog base band signal, and which has a numerical cutoff frequency value that does not exceed half the bit rate of the preamble, a comparison circuit that is connected to the output of the low-pass filter and compares an output voltage of the low-pass filter with prescribed threshold values, and a determining circuit that determines a preamble has been detected when the comparison by the comparison circuit indicates that an absolute value the low-pass filter output voltage does not exceed a prescribed threshold value for a prescribed time period.
摘要:
An optical-electronic integrated circuit device capable of three-dimensionally transmitting optical signals between plural semiconductor substrates on each of which an integrated circuit is previously formed. At least one of the light emitting elements and the light receiving elements are formed on the semiconductor substrate which transmits the light propagated between these elements. In this manner, signals may be transmitted in a direction perpendicular to the semiconductor substrate even without specifically processing the semiconductor substrate. Additionally, signal distortion, transmission losses, mutual intervention or delay are not incurred. For two-dimensionally connecting plural three-dimensionally integrated optical-electronic integrated circuit devices in a direction parallel to the semiconductor substrates, the circuit devices are arrayed on an optical interconnection base plate, and light signals are transmitted by means of a pair of inclined surfaces which are formed on the optical interconnection base plate and which are arranged facing the light emitting element and the light receiving element, and the light waveguide channels defined between these inclined surfaces. This drastically increases the operating speed of the circuit device and the integration degree.
