A portable electronic device includes: a communication block configured to communicate with another portable electronic device different from said portable electronic device; an information acquisition block configured to acquire relation information that is information about a relation between a user of said portable electronic device and a user of said other portable electronic device from an external server through a network when said communication block communicates with said other electronic device; and a notification block configured to notify the user of said portable electronic device of the relation information acquired by said information acquisition block.

Portable electronic device, information processing method, and program

Disclosed herein is a mobile terminal including: a reproducing section adapted to reproduce a first distance measurement signal; a recording section adapted to record the first distance measurement signal and a second distance measurement signal output from other mobile terminal; a time difference measurement section adapted to measure a first difference between recording start times of the first and second distance measurement signals; a communication section adapted to receive a second difference between recording start times of the first and second distance measurement signals from the other mobile terminal, the second difference being measured by the other mobile terminal; and a distance calculation section adapted to calculate a distance to the other mobile terminal by multiplying the subtraction result between the first and second differences by the speed of sound.

Mobile terminal, wearable terminal, sonic distance measurement system, and sonic distance measurement method

Disclosed herein is a non-reciprocal circuit device includes: a first substrates including a magnetic plate having a circular surface and a dielectric ring having an annular surface, the circular surface and the annular surface being substantially coplanar; a second substrate; a center conductor provided between the first substrate and the second substrate; and a permanent magnet that applies a magnetic field to the center conductor. The center conductor includes: a main conductor portion positioned on a straight line extending from a center of the circular surface to an outer periphery of the annular surface; and a protrusion portion having a width smaller than a width of the main conductor portion, and wherein at least a part of the protruding portion is positioned on the annular surface.

Non-reciprocal circuit device and communication apparatus using the same

Disclosed herein is a non-reciprocal circuit device includes: a substrates including a magnetic plate having a circular surface and a dielectric ring having an annular surface, the circular surface and the annular surface being substantially coplanar; a center conductor disposed on the substrates; and a permanent magnet that applies a magnetic field to the center conductor. The center conductor includes: a main conductor portion positioned on a straight line extending from a center of the circular surface to an outer periphery of the annular surface; and a branched conductor portion extending in a radial direction of the substrate from the center of the circular surface. The branched conductor portion includes: a wide portion disposed on the circular surface; and a narrow portion having a width smaller than that of the wide portion and disposed across a boundary between the circular surface and the annular surface.

In a pipe in which a plate material is formed into a cylindrical shape, and a one-side edge portion and the other-side edge portion are joined to each other to thereby form a pipe body, a fitting convex portion is integrally formed on the one-side edge portion of the pipe body, and a fitting concave portion is integrally formed in the other-side edge portion so that the fitting convex portion is fitted into the fitting concave portion. Further, a top end portion of the fitting concave portion is bent and received in a recess portion formed in the pipe body.
