摘要:
A communication device includes a proximity wireless communication antenna for contactless proximity wireless communication with a counterpart instrument antenna in proximity, a first wireless communication processing unit to conduct contactless proximity wireless communication using the proximity wireless communication antenna, a second wireless communication processing unit to conduct wireless communication in a wireless communication format different from that of the first processing unit, a ground potential to be disposed in a surrounding area of the proximity wireless communication antenna and to be connected to a counterpart instrument ground potential when the instrument is in proximity, a detection unit to detect that the counterpart instrument is connected while allowing contactless proximity wireless communication, and a control unit to restrict wireless communication with the second processing unit when the detection unit detects connection and to remove the restriction after connected to the counterpart instrument ground potential with the ground potential during the restriction.

An antenna includes: a differential linear antenna that includes two antenna elements, which have a predetermined length, arranged so as to be separated from each other for to be symmetrical with respect to a line that becomes a reference and provided with voltages having opposite polarities; and a patch antenna having a flat plate shape which is arranged to be parallel to a plane, on which the differential linear antenna is arranged, and in which a feeding point is disposed in an area interposed between virtual planes that are perpendicular to the plane and pass through extended lines of the antenna elements.

Disclosed herein is a crystallization apparatus for use in the crystallization of L-.alpha.-aspartyl-L-phenylalanine methyl ester. The stirring blade of the crystallization apparatus is composed of a band plate member for sweeping the bottom of a vessel and rod- or band plate-members arranged thereon and extending substantially vertically and horizontally.
