Title: Manufacture of magnetron anode
Inventor: SATO ATSUSHI
IPC: H01J23/20
Filed: 1995-07-04
Abstract: PROBLEM TO BE SOLVED: To enable formation of stable weld beads whenever necessary and to enhance reliability by setting the focal position of a laser beam at a predetermined position when welding the seams of a cylindrical component together using the laser beam. SOLUTION: When copper material is molded into a round shape to provide a cylinder 2 that serves as an anode cylinder, both end faces of the copper material do not make full contact with each other but leave a V-shaped space between. To eliminate the space, with seams 3 brought into close contact by application of pressure a laser beam 4 is applied to a welded portion from a diagonal direction while keeping an angle of about 20 deg. to a vertical line to melt part of the copper to join together the seams, which are then cooled. In this case, the beam 4 is applied from a laser oscillator via a condensing lens 5, with the focal position F of the beam 4 set at a position that is at a distance G from the surface of the cylinder 2 toward the laser oscillator.  Therefore a magnetron anode that is stable as to both the welded part of the seams 3 of the cylindrical component and beads can be obtained.

Title: Fluctuation analyzer
Inventor: MIYAJIMA TORU
IPC: G10L25/48
Filed: 1995-07-05
Abstract: PROBLEM TO BE SOLVED: To make it possible to analyze timing fluctuation in a relatively short time with a small memory capacity by setting the time when the digital signal obtained by the A/D conversion of the output of a filter exceeds a threshold as the generated time of an event, and obtaining the frequency spectrum from the time interval. SOLUTION: A effective value circuit 2 obtains the effective value of the analog signal outputted from a signal input part 1. A filter circuit 3 takes out the frequency component, wherein sufficient information required for the analysis of timing fluctuation remains. The analog signal, whose frequency is made low with the filter circuit 3, undergoes A/D conversion 4 and stored into an analysis-data storing memory 5. A fluctuation analysis circuit 6 sets a threshold for the digital data stored in the analysis-data storing memory 5, sets the time when the level of the threshold is exceeded as the generated time of an event and sets the difference between the generated times as the time interval of the occurrence of the event. Thus, the analysis of the timing fluctuation is performed.
