Abstract: A planar light source includes a support member; a light guide member including a first surface located proximate to an upper surface of the support member, a second surface opposite to the first surface, and a through hole extending from the first surface to the second surface; a light source unit including a light-emitting element and a wavelength conversion member that covers an upper surface and a lateral surface of the light-emitting element and disposed on the support member at a position of the through hole; a light-transmissive member disposed between the light source unit and the light guide member in the through hole; and a light adjustment member disposed on the light source unit and the light-transmissive member. An upper surface of the wavelength conversion member of the light source unit is located higher than the second surface of the light guide member.

Abstract: A missile to be fired from a barrel contains a tail, a tail sleeve attached to the tail, a stop element fixed to the tail sleeve, and a movable structural part disposed at the tail. Fin assembly wings are provided and are to be released from a subcaliber launch position to an overcaliber functional position by the movable structural part moving toward the stop element through a given distance. A pressure area is disposed between the tail end surface and the movable structural part. A propellant gas enters the pressure area during the firing of the missile, for moving the movable structural part away from the tail end surface against the stop element after firing. Bearing shafts are supported by the tail sleeve, the fin assembly wings are configured as a wrap around tail fin assembly held about the bearing shafts.

Abstract: A purpose of the present invention is to improve a reception sensitivity when simultaneous transmitting/receiving operations are not carried out in a mobile communication apparatus capable of performing the simultaneous transmitting/receiving operations. The mobile communication apparatus, according to the present invention, is comprised of an antenna selector (13) for switching a connection between a first antenna A (11) and a second antenna B (12), and is selectively connected with a transmission system which contains a transmission-side filter (14) and a transmitting unit (16), and with respect to a reception system which contains a reception-side filter (15) and a receiving unit (17).
