摘要： 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.

摘要： 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.

摘要： A cooling device for a semiconductor component which increases mechanical strength thereof and reduces a pressure loss of coolant. Plate members constituting the cooling device are formed with flow passages such as coolant supply and discharge openings, grooves divided by ridges, and through portions separated by projections or partitions. The ridges, projections, and partitions are joined to a adjacent plate member to increase the joining strength, which is further increased by forming the ridges, projections, and partitions of different plate members at the same positions. In the case of laminating the plate members having surfaces formed with solder layers, a number of minute vacant spaces are formed in those joining faces of the plate members which are not formed with passages, etc., and solder filets are formed over the entire joining faces to increase the joining strength. The grooves and through portions can be formed by chemical etching together with outer shapes of the plate members. A plurality of plate members can be fabricated from a single sheet material at a time.
