IPC: B23K26/21
Filed: 1984-10-12
Abstract: PURPOSE:To improve shaping accuracy and working efficiency by irradiating a heat source such as laser beam again to a weld zone upon ending of welding to remelt the surface of the weld zone. CONSTITUTION:A detector 11 for the thickness of materials to be welded and a detector 12 for the thickness of the weld zone are provided just before a laser beam processing head 10 in the moving direction thereof. The build-up height of the weld zone 2 is calculated by a comparator 13 from the difference in the outputs of the detectors 11 and 12. A calculator 15 calculates the irradia tion energy density necessary for remelting the surface of the weld zone 2. The head 10 traces again the weld zone 2 while holding clamps 3, 4 upon ending of welding of the zone 2. The calculated value of the build-up height determined by the comparator 13 is inputted via the calculator 15 to a head driving device 16 by which the weld zone 2 is remelted and shaped by the heat input of the adequate quantity of the energy density. The shaping accuracy and working efficiency are improved by the above-mentioned method.

Title: Maximum power follow-up control method for photovoltaic power generating set
Inventor: YAMADA YOUJI
IPC: G05F1/67
Filed: 1993-08-31
Abstract: PURPOSE:To prevent the large fluctuation of an action point caused by the change of sunshine conditions by controlling the command value voltage based on the difference between the electric power of a solar battery and the electric power of a blind sector and in the prescribed step width and thus defining the next command value voltage. CONSTITUTION:An arithmetic part 8 calculates the output voltage and current of a solar battery that are measured at a measuring part 7. Thus the present detected power is obtained. An operating area deciding part 10 collates the present detected power with the power value of a blind sector obtained by controlling the prescribed set power value to the precedent detected power and decides a specific area of a maximum output operating voltage characteristic curve where the output of the solar battery is included. Then a command value voltage producing part 11 controls the command value voltage by the voltage of the prescribed step width and based on the difference from the power value of the blind sector and then sets the next command value voltage. Thus the detected power of the solar battery is not merely collated with the precedent detected power but collated with the power value of the blind sector. Therefore a large shift of a control point can be prevented despite some change of the output characteristic of the solar battery.

Filed: 1993-08-31
Abstract: PURPOSE:To suppress the noise at the time of the special reproduction of a laser disk or the like and at the time of cutting off input signals by adjusting synchronization protective length at the time of cancelling synchronization corresponding to a noise amount included in reception television signals. CONSTITUTION:When the noise amount detected from a noise amount detection circuit 3 is less than a prescribed level, the synchronization protective length value of a synchronization protective length adjusting circuit 4 is switched to a shortened value (a) by changeover control signal and the synchronization protective length at the time of the cancellation of a synchronization pull-in/cancellation circuit 7 is shortened. Thus, noise generation at the time of cancelling the special reproduction of the laser disk or the like and at the time of inputting signals can be prevented. On the other hand, when the detected noise amount is more than the prescribed level, the synchronization protective length of the synchronization protective length circuit 4 is switched to an extended value (b) by the changeover control signal and the synchronization protective length is extended. Thus, synchronization is prevented from being cancelled, sound interruption due to unnecessary mute is prevented, a synchronization pull-in operation length is shortened by the adjusting means of a synchronization pull-in operation period and synchronization pull-in is facilitated.
