Abstract: A data transmitting device divides application data into packets, transmits the packets, and continuously carries out packet transmission while receiving acknowledgement from a receiving device of the transmitted packets. The application data to be transmitted is stored in a data storage area of a data storage unit. The data is read from the data storage area, a sequence number is set, and the data is transmitted as the packet. If the read data is within a predetermined length from an end of the application data, a copy of the read data is saved in a temporary buffer area of the data storage unit. When data of a sequence number before that of first data of next application data is to be transmitted after transmission of the next application data is started, the data is read from the temporary buffer area of the data storage unit.

Abstract: A laser beam oscillated from a laser source is folded in its path by first and second plane mirrors and enters a beam expander. The surface of each plane mirror is deteriorated with illumination by the laser beam and the reflectance is reduced. To avoid a light quantity of the laser beam entering the beam expander from being reduced below a reference value, when the laser beam is illuminated over a certain time, a position on each of the first and second plane mirrors at which the laser beam is illuminated is changed by a structure for rotating and/or translating a reflecting surface of each plane mirror on a plane, which includes the plane mirror, while an optical axis is kept same. Thus, the useful life of each plane mirror can be prolonged without displacing the optical axis.

Abstract: A laser beam oscillated from a laser source is folded in its path by first and second plane mirrors and enters a beam expander. The surface of each plane mirror is deteriorated with illumination by the laser beam and the reflectance is reduced. To avoid a light quantity of the laser beam entering the beam expander from being reduced below a reference value, when the laser beam is illuminated over a certain time, a position on each of the first and second plane mirrors at which the laser beam is illuminated is changed by a structure for rotating and/or translating a reflecting surface of each plane mirror on a plane, which includes the plane mirror, while an optical axis is kept same. Thus, the useful life of each plane mirror can be prolonged without displacing the optical axis.
