Title: Ion implantation method and its device
Inventor: YANASE TOSHINOBU
IPC: H01L21/265
Filed: 1987-03-31
Abstract: PURPOSE:To prevent occurrence of defects in ion implantation by changing a frequency of scanning, which is performed in at least one of two scanning directions, into a different frequency during ion beam irradiation so that ion implantation is performed synchronizing with specific frequencies. CONSTITUTION:In an ion implantation method where ion beams 22 are scanned in two directions by scanning means 25, 26 and irradiated on a semiconductor substrate 36, a frequency of scanning in at least one of two scanning directions is changed into a different frequency during this ion beam radiation. The ion beam scanning means 25 is connected with two oscillators 31a and 31b. The ion beam scanning means 26 is connected with three oscillators 32a to 32c. Switches 33 and 34 are provided to change their oscillators. When oscillation frequencies are thus changed for scanning the ion beams, synchronization time for the frequencies can be shortened and so unevenness in ion implantation can be decreased.

Title: Hand rail device for variable speed passenger conveyer
Inventor: AOE SHINICHIRO
IPC: B66B23/26
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To smoothly drive a hand rail section by providing a means for keeping a mutual closing angle of both links above a designated one. SOLUTION: Since a pair of a reference guide roller 11 and a side guide roller 12 makes one unit, they are excellent in traceability to a reference guide rail 8 and a side guide rail 9, and are not derailed on the way. A part 18 is a holding bracket provided on a linked body 12a of the side guide roller 12 in order to keep an angle formed by a link 10 and another link 10' above a designated one. Since the adjacent link 10 abuts on angle holding bracket 18 in a reversed part, and a carrying force of a hand rail section is transmitted to an upper side link, by providing the angle holding bracket 18, transmittance efficiency of carrying force is remarkably increased in comparison with the case without the angle holding bracket 18.
