Abstract: A signal transmission device having a capacitor coupler includes a semiconductor substrate, a low voltage circuit region, an insulating film formed on the semiconductor substrate, a lower electrode formed on the semiconductor substrate via the insulating film, and an upper electrode disposed opposite to the lower electrode via the insulating film interposed therebetween. A shield portion includes a conductor to which a low voltage is applied is provided between the lower electrode and the upper electrode and the low voltage circuit region. When a stacking direction of the lower electrode and the upper electrode is defined as a height direction, the shield portion is located higher than the low voltage circuit region and has an eaves part extending on an opposite side with respect to the lower electrode and the upper electrode.

Abstract: A light-emitting device includes an optical member including first and second light emitting elements, first and second light condenser portions, and a light guide portion. The first light condenser portion is disposed at a position corresponding to the first light-emitting element, and condenses a portion of light emitted from the first light-emitting element. The second light condenser portion surrounds the first light condenser portion, and condenses a portion of the light that is not incident to the first light condenser portion among the light emitted from the first light-emitting element. The light guide portion is disposed at a periphery of the second light condenser portion and at a position corresponding to the second light-emitting element, and guides light emitted from the second light-emitting element by causing total reflection in an interior of the light guide portion.

Abstract: An information transmission system includes a ground system provided to a track and an onboard system installed in a train. The ground system includes two (M=2) track antennae selected from N types of track antennae with different resonance frequencies. The two track antennae are arranged side by side in a left and right direction relative to a traveling direction of the train. When the train passes through a position where the ground system is provided, the onboard system detects the two track antennae at once and can determine the resonance frequencies of the track antennae.

Abstract: A loudspeaker includes two first magnetic portions arranged in parallel and a second magnetic portion disposed between the two first magnetic portions on a bottom plate. An annular top plate is provided to the two first magnetic portions and disposed in such a manner as to form a magnetic gap with respect to the second magnetic portion. The first magnetic portions and the second magnetic portion are magnetized in the opposite directions in a direction in which the bottom plate, the first magnetic portions and the top plate are stacked. The top plate includes two main bodies provided to the two first magnetic portions and two bending portions connecting between two first magnetic portions and bending toward the bottom plate.
