摘要： In a laser-power control method, a power of laser light emitted from a laser-light emitting element and a driving current for driving the laser-light emitting element are detected. An approximate expression indicating a driving-current to light-power characteristic of the laser-light emitting element is updated on the basis of the detected light power and the detected driving current while sequentially increasing accuracy. A command driving current corresponding to a target light power is calculated by using the updated approximate expression. The laser-light emitting element is driven on the basis of the calculated command driving current so as to output the target light power.

摘要： In a radio communication such as a radio telephone system or the like, a transmission channel which can accommodate a change in a transmission capacity is set. While a terminal apparatus and a base station are in communication for transmitting a predetermined information using a predetermined transmission channel, a signal requesting to set another transmission channel is transmitted using a part of the predetermined transmission channel to initiate communication between the terminal apparatus and the base station through the other transmission channel.

摘要： In order cope with a change of the transmitting capacity in a wireless telephone system. A number of transmission channels are set within the transmission frequency band prepared for each base station. When a communication is made between the terminal equipment and the base station through the transmission channels, at least a first transmission channel and a second transmission channel are set as the transmission channel depending on a class of information to be transmitted. The first transmission channel is set to have a fixed transmitting capacity and the second transmission channel is set so that the minimum transmitting capacity may be defined and the transmitting capacity greater than the minimum transmitting capacity may be set depending on the setting condition of the transmission channels within the transmission frequency band prepared.
