IPC: B23K26/00
Filed: 1988-03-30
Abstract: PURPOSE:To enable the working minimizing the damage onto a substrate and the peripheral part by providing the means of making the image forming position of an objective lens and the surface of the body to be worked coincident with an stopping the irradiation of a pulse laser output by deciding the state of the film removing work. CONSTITUTION:A position adjusting means 9 is driven by the movement control signal fed from a control means 12 to vary the distance between an objective lens 8 and the surface of the body W to be worked. The variation in the inclination of the edge part of the slit image obtd. from the video signal of a line signal extracting means 11 and the brightness of the center part is detected by the control means 12. The driving of the position adjusting means 9 is stopped at the time when the brightness of the center and the inclination of the edge part become max. and the surface of the body W to be worked and the combined position of the slit image by the objective lens 8 are made coincident. The size of a slit body 4 is then adjusted and the irradiation of the laser output by a pulse laser 3 is started. The signal of high brightness existing prior to working becomes a signal of flat distribution at the time when the defect is removed. This time is decided as the film removing work being completed, a radiation stop control signal is given to the pulse laser 3 and the irradiation of the laser output is stopped.

Filed: 1978-06-27
Abstract: PURPOSE: To detect the leak point of a burried tubular body such as an oil-filled cable with high precision from the surface side by use of a tracer gas.  
     CONSTITUTION: In pressure feeding at a predetermined pressure an insulating oil 33 from an oil feed tank 1 through a pump 2 into a cable 3, a tracer gas is admixed in the oil 33.

Filed: 1978-06-27
Abstract: PURPOSE: To obtain a tape end detection mechanism which is operated surely and can be made small-size, by detecting the coming of the tape end on a basis of the cancel of the following force of a following material, which is operated while following a driving means, dependent upon the rotation stop of a reel axis.  
     CONSTITUTION: When magnetic tape 40 continues to run in the arrow direction as shown in the figure and a driving force for following material 56 exists, following arm 57 continues the following operation for cam 45. However, when the running of magnetic tape 40 is stopped and the rotation of reel axis 24' is stopped, the driving force for following material 56 disappears, and following arm 57 does not perform the following operation for cam 45, and therefore, axis pin 69 of driving piece 68 is moved from the lower part of cam 62 to higher part 61 to move moving material 72 in the right direction in the figure. Consequently, switching board 34 connected to moving material 72 is rotated in the clockwise direction from the state in the figure, and the tape is caused to run in the direction opposite to the arrow. Thus, a tape end detection mechanism which is operated surely and is small-size can be obtained.
