Abstract: A time information obtaining device and a radio-controlled timepiece are shown. According to one implementation, the time information obtaining device includes the following. A code identifying section identifies each code of a code string in a radio wave. A first portion parity calculating section calculates a portion parity where a parity bit of a variable code is subtracted from a parity code showing a parity bit for a code string portion. A first portion parity deciding section decides a portion parity based on a calculated number of portion parities. A second portion parity deciding section obtains a portion parity from an invariable code other than the variable code. A parity confirming section confirms a match between the portion parities decided by the first portion parity deciding section and the second portion parity deciding section.

Abstract: An adjustment method for an antenna device including an antenna, an adjustment circuit including first and second circuits connected in series with the antenna and a communication circuit connected with the adjustment circuit includes: determining constants of the first circuit such that at two frequencies, values of first resistance of first impedance as viewed from an output end of the first circuit toward the antenna each are equal to resistance of target impedance, and absolute values of first reactance of the first impedance are different from one another; and determining constants of the second circuit such that at the frequencies, while values of second resistance of second impedance as viewed from an output end of the adjustment circuit toward the antenna are kept at the values of the first resistance, values of second reactance of the second impedance each are a complex conjugate with reactance of the target impedance.

Abstract: An electronic device includes a ring-shaped antenna element, a conductor and a dielectric. The conductor has the same potential as GND. The dielectric is interposed between the antenna element and the conductor. The antenna element, the dielectric and the conductor are disposed so as to lie on top of one another in plan view.

Abstract: Disclosed is a solar panel being divided into a plurality of cells and including: a light transmissive power generation region which is a central region in a diameter direction of a ring-shaped member and in which extending thin line power generators are arranged in parallel in a direction substantially orthogonal to the extending direction; and a periphery power generation region which is a periphery region of the light transmissive power generation region and in which a part of the cells is arranged along a circumferential direction. The cells include a composite cell including at least a part of the periphery power generation region and at least a part of the light transmissive power generation region. A first cell and a second cell different from the first cell are respectively arranged on one end side and on the other end side in the diameter direction of the ring-shaped member.

Abstract: An embodiment of an electronic timepiece includes a cylindrical exterior case, a bezel and a windshield member. In the exterior case, a circuit board is housed. The bezel is formed of a metal material to be ring-shaped, includes an inward flange part that projects from an inner side surface toward a center of the ring-shaped bezel, is arranged on an outer upper side of the exterior case and is electrically connected with the circuit board. The windshield member is formed of a transparent dielectric substance, arranged in the bezel and supported by the inward flange part. The bezel is configured to resonate with a radio wave having a desired frequency by adjustment of at least one of (i) a relative permittivity of the dielectric substance and (ii) an area of an overlap region where the inward flange part and the windshield member overlap each other.

Abstract: Disclosed is an electronic device. The electronic device includes a display section, at least one substrate, a control section, a connecting section, a receiving section, and output wiring. The at least one substrate includes a plurality of wiring layers overlapped as a whole. Output wiring is provided on the first layer among the plurality of wiring layers and connects each of the plurality of the output terminals and the control section. From a planar view of the substrate, a bar antenna is attached on a face of a second layer on a side opposite of the first layer, in a position between positions corresponding to positions of the connecting section and the control section. The output wiring crosses between regions corresponding to both edge regions including both edges of the bar antenna.
