Abstract: As described above, when a communication control device receives a message transmitted from a user terminal, the communication control device specifies a destination of the message from contents of the message, specifies a type of communication service available by a user of the specified destination, and creates a message suitable for the specified type of service. Then, the communication control device transmits the created message to the specified destination.

Abstract: An electronic coupon management system includes a coupon server apparatus. The coupon server apparatus includes an interface unit, a commercial facility ID (Identification) retaining unit, a submission receiving unit, an electronic coupon generating unit, and an electronic coupon publicizing unit. The interface unit is publicized to an external terminal apparatus via a network. The commercial facility ID (Identification) retaining unit retains commercial facility IDs. The submission receiving unit receives submission of an electronic coupon via the interface unit along with selection of at least one commercial facility ID from the commercial facility IDs retained in the commercial facility ID retaining unit. The electronic coupon generating unit generates the submission-received electronic coupon in a lock state which is cancellable by the selected commercial facility.

Abstract: The basic unit of a modern electron microscope incorporates a computer, a ROM, and a RAM. According to this invention, an external computer connected with the microscope also has a RAM. In the initial condition, the contents of the ROM in the microscope are read into the RAM of the external computer. When the magnification is set to a desired value, the external computer selects currents which are fed to the electron lenses and deflector coils, corresponding to the two values of magnification closest to the desired value of magnification, from the data stored in the ROM. Then, the computer calculates the currents which should be fed to the lenses and coils, corresponding to the desired value of magnification, from the selected values. The obtained data is held in either RAM. The external computer controls the lenses and coils according to the data held in this RAM.

Abstract: Under certain conditions, the electron beam from the electron gun of an electron microscope is deflected by deflecting means in such a way that the beam impinges on one point on a filmy crystalline specimen at a specific tilt angle while the direction of the tilt is rotated, to obtain an electron micrograph of the specimen. In the conventional astigmatism correcting device, however, the rotation of the direction of the tilt makes it impossible to correct the astigmatism of the objective lens of the microscope which forms such an electron micrograph. In the instrument according to the present invention, astigmatism correcting signals synchronized with the rotation of the direction of the tilt are supplied to the astigmatism correcting device so that the obtained electron micrograph may be unaffected by the astigmatism of the objective lens despite the periodic rotation of the direction of the tilt.

Abstract: A scanning electron microscope having a plurality of annular shaped electron detectors. The ratio of two detector output signals is compared with some constant value indicative of a component of the specimen. On the basis of the comparison the output signal of one detector is passed or not passed to an image display means to provide an image indicative of said component.
