A semiconductor-laser-pumped solid-state laser apparatus (11) which operates laser oscillation by exciting a solid-state laser medium (1) using a semiconductor laser (2) is described. The semiconductor-laser-pumped solid-state laser apparatus (11) has driving current switching means for switching, in accordance with an external control signal, a driving current between a state in which the driving current not less than an emission threshold value of the semiconductor laser is supplied to the semiconductor laser, and a state in which the driving current smaller than the emission threshold value of the semiconductor laser is supplied to the semiconductor laser. An external control apparatus sends an external control signal to a semiconductor-laser-pumped solid-state laser apparatus even if the laser radiation of the solid-state laser is stopped. Therefore, the electric power consumption of a laser machining system can be reduced and the lifetime of the semiconductor laser can be prolonged.

An automatic locking system for vehicles includes an electronic control unit. If it is determined that an electronic key is not located in a communication area of an inside-cabin transmitter, the control unit determines whether or not the electronic key is located nearby. As a result, if the electronic key is determined as being located nearby, followed later by a determination that the electronic key is not located nearby, comparison history is stored in a memory. If it is determined that comparison history is stored in the memory and four entry-and-exit doors are closed, the four entry-and-exit doors are locked.
摘要:
A high-power laser unit capable of accurately correcting laser output from low to rated outputs, even when the laser unit has a laser power monitor which may be affected by environmental factors inside or outside the laser unit, by effectively reducing environmental factors. The laser unit has a laser power monitor for measuring laser output, and a laser controller for correcting the laser output by correcting an amount of excitation energy to a laser power supply so that a measurement value coincides with a laser output command value. The laser unit has a laser output commanding part for generating a laser output command. When it is not necessary to correct the laser output command, the laser output command is converted into an excitation energy command value and sent to the power supply. Otherwise, an output correcting part of the laser controller corrects the laser output command.

In the travel control method in the mobile robot system including a plurality of mobile robots and the control station for controlling these mobile robot, the control station directs one of a plurality of mobile robots to the destination robot, responding to the direction, searches the route to the destination directed by the control station and sends the result to the control station. The control station which receives this in formation checks if the travel path searched by the mobile robot is already reserved by other mobile robots or not by the reservation table. If not, the control station informs the reserve completion to said mobile robot. The mobile robot which received the information of the reservation completion travels automatically along the travel path which is already reserved. In addition, said control station, when there are other mobile robots which disturb the travel of each mobile robot, directs the robot to wait or to take an alternate route according to the situation, or directs other mobile robots that disturb the travel to halt.
摘要:
A laser unit having a preparatory function for activating the unit and an activation method for the unit, capable of stabilizing the temperature of each component of the laser unit in the preparation stage when the laser unit is activated in a low-temperature or high-temperature environment, and then effectively judging completion of the preparation. During a period of time Ta from T1 to T2, a first trial of laser oscillation is performed. After a period of time Tb in which the laser is not oscillated, a second trial of laser oscillation from T3 to T4. Such an operation is repeated until a predetermined criterion is satisfied. Laser output values P2, P4, P6, . . . , at the last moment in each trial of laser oscillation are recorded. Then, each difference between the laser outputs at the last moments of two neighboring or continuous trials, is calculated. When the difference is lower than a predetermined criterion value, the preparation of the laser unit is judged to be completed.
