Title: Photoscanner
Inventor: ANDOU MORITOSHI
IPC: G02B26/10
Filed: 1982-06-23
Abstract: PURPOSE:To improve scan efficiency without increasing the diameter of a rotating mirror, by using plural rotating mirrors which each have a 1/N-period difference in the phase of scanning periods successively. CONSTITUTION:Light from a laser light source 1 is passed through an expander 2 and split by a splitter 11 into two pieces of parallel luminous flux 12 and 13, which are made incident to rotating mirrors 14 and 15. The mirrors 14 and 15 are in the same shape and of the same size and fitted to a common rotating shaft 16 in such a way that the surface normal 142 of one reflecting surface 141 of the mirror 14 and the surface normal 152 of the one reflecting surface 151 of the mirror 15 contain an angle THETA/2 and the reflecting surfaces are shifted in position. The mirrors 14 and 15 are rotated to scan the pieces of parallel luminous flux 12 and 13 on the same line on a pattern surface 6 as shown by an arrow X. When each scan efficiency eta of the mirrors 14 and 15 is one-third, such timing of scanning in the direction of the arrow X that a scan is made twice in one scanning period is obtained, increasing the scan efficiency by twice (eta=2/3).

IPC: H02K9/02
Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To provide dynamo electric machine suppressing the heat generation of an armature coil containing a rectifier part. SOLUTION: Since the diameter D1 of a projection part outside diameter 20f in an outer coil end part 20b and the outer diameter D3 of the sliding contact parts of brushes 81 and 81b are formed to be larger than the diameter D2 of an upper conductor 20e by a prescribed size, the area of the brush sliding contact parts can largely be secured and current density is suppressed. Thus, heat generation at the part can be suppressed. Since the projecting part outside diameter 20f itself is exposed to air, it is brought into contact with peripheral air by rotation and it is cooled. Then, the outer coil end part 20b and the upper conductor 20e, which are connected to the part, and brushes 81 and 81b are correspondingly and satisfactorily cooled.
