摘要:
In an optical waveguide device, a rectangle, which uses a filter insertion groove as its diagonal line and uses points on filter insertion grooves adjacent to the above filter insertion groove as its apexes, is assumed as a unit rectangle, and the size of the optical waveguide device is set to an integer multiple of the unit rectangle. In this case, even if filter insertion grooves are formed in a state in which a plurality of the optical waveguide devices are disposed in matrix, the respective optical waveguide devices can be formed in the same shape. Further, the filter insertion grooves formed to the respective optical waveguide devices do not divide portions other than the target portion of other optical waveguide devices. Therefore, the manufacturing processes of the optical waveguide device can be simplified and are suitable for mass production, and manufacturing cost can be suppressed thereby.

It is an object of the invention to provide an ejector mechanism and a socket which are free from fear of breakage and in which a smooth and reliable pulling out operation can be obtained. In the invention, an ejector mechanism includes an ejector having: an ejector which is interposed between the socket body and an attachment face of the relay, and in which a part of an arcuate face is in contact with an attachment face of the relay; and tilting enabling means, journalled on the socket body, for gradually displacing a contact position between the pushing-up curved face and the attachment face of the relay with using the journal portion as a tilting fulcrum, and, when the tilting enabling means performs a tilting operation, the contact position of the pushing-up curved face is moved in a pushing-up direction along which the relay is separated from the socket body, with using the journal portion as a tilting fulcrum.

An antenna device and non-contact transmitter/receiver device constituting at least the same includes a first conductor unit; a second conductor unit that is electrically connected to the first conductor unit; and a third conductor unit that is electrically connected to the first conductor unit and the second conductor unit. The first conductor is placed along a first virtual plane, the second conductor unit is placed along a second virtual plane, and the third conductor is placed along a third virtual plane. In this antenna, the plane that includes the first conductor unit, the plane that includes the second conductor unit, and the plane that includes the third conductor unit are perpendicular to one another.
