Title: Detection method for groove position in electron beam welding
Inventor: SHIBAKITA SADAO
IPC: H01J37/22
Filed: 1988-04-11
Abstract: PURPOSE:To improve the aiming positional accuracy of an electron beam and the working efficiency by arranging the telescope separating a scanning beam and a route and detecting a groove and beam position with emitting the scanning beam. CONSTITUTION:The body 4 to be welded is arranged on the table 5 of the inside of a vacuum welding chamber 3 and a telescope 7 is arranged on the route of an electron beam 6 and a separate route.

Abstract: PURPOSE:To detect the freezing of a road surface with a high probability even in a sudden change in weather in the night after a rainfall or a snowfall by judging the freezing when both a road surface temperature and the difference between the road surface temperature and an atmospheric dew point temperature are below 0 deg.C and a high humidity duration has a predetermined condition. CONSTITUTION:A road surface temperature signal output unit 1, an atmospheric temperature signal output unit 2 and an atmospheric humidity output unit 3 respectively convert a road surface temperature, an atmospheric temperature and an atmospheric humidity to signals. An arithmetic unit 5 calculates the difference between the road surface temperature and an atmospheric dew point temperature calculated by a dew point temperature calculator 4. A freezing judging unit 6 judges a freezing based on the data of the arithmetic unit 5 and the output unit 1 when the road surface temperature and the difference between it and the atmospheric dew point temperature are both below 0 deg.C. On the other hand, when the duration of a high humidity condition exceeds a prescribed time, a humidity condition judging unit 9 outputs a freezability signal based on atmospheric humidity data from the output unit 3 stored in an atmospheric humidity storage 8. A freezing judging unit 10 judges the freezing when a time at which the road surface temperature from the output unit 1 becomes below 0 deg.C is within a prescribed time from a high humidity duration ending time. A freezing alarm is outputted in response to the outputs of the judging units 6 and 10.

Filed: 1983-05-20
Abstract: PURPOSE:To collect the 1st toner mixing with the 2nd developer easily by determining the order of electrostatic charging trains of the 1st and the 2nd developers. CONSTITUTION:The 1st and the 2nd developing devices 14 and 15 which employ magnetic brush developing devices use a two-component developer. In this case, such charging trains of the respective developers that T1<C<T2 (where T1 and T2 are the 1st and the 2nd toner particles and C is the 1st and the 2nd carriers) are used. The 1st electrostatic latent image charged positively is developed with the 1st toner charged negatively and guided into the 2nd developing chamber 15, and when the 2nd electrostatic image charged negatively on a photosensitive body 1 is developed with the 2nd toner, a magnetic brush contacts the 1st toner, which mixes with the 2nd developer. At this time, the 1st toner is held in negative by the charging train, so the toner is collected while sticking to a bias roll easily.
