Title: Side light type surface light source device
Inventor: SASAKO HIROMI
IPC: G02B6/00
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To make it possible to avert the occurrence of unequal luminance and to effectively utilize an exit surface even when a reflector, etc., are held on a light transmission plate by double coated adhesive tapes by arranging a light shielding member for shielding illumination light at the end face of a member to be held on the exit surface or slope of the light transmission plate. SOLUTION: Even if the bright line by the edge E of the light scattering light transmission body 11 and the dark band by an incident surface 12 are obscured by shielding the edge E and forming the incident surface 12 as a rough surface, unequal luminance arises in exit light when the double coated adhesive taps 15 and 18 are stuck to the light scattering light transmission body 11 and are held at the slope and the exit surface and the reflector 19 is held on the exit surface. The illumination light leaking from the end face is, therefore, shielded by the double coated adhesive taps 15 and 18 and the light shielding member 17 arrange at the end face of a reflector 19. The bright glittering of the double coated adhesive taps 15 and 18 and the end face of the reflector 19 by incoming light, etc., is obviated.  As a result, the occurrence of the brightline is effectively averted and the unequal luminance is decreased.

Filed: 1991-03-01
Abstract: PURPOSE:To maintain the best drum current at all times even if ambient conditions of temperature, etc., are changed, to secure the excellent picture quality performance of a copy, and to improve environmental resistance by holding the drum current at a specific value. CONSTITUTION:When the drum current Id increases above a specific value, the potential of a photosensitive drum 30 which is detected by the potential sensor of a voltage control means 22 becomes high. An external control voltage Vc applied with a detection signal corresponding to the potential of the photosensitive drum from the potential sensor 24 becomes high as the potential of the photosensitive drum 30 increases and is applied to a variable constant voltage circuit 12. Then a grid voltage Vg, i.e., grid current Ig increases and the drum current Id decreases because of a relation Id=Ih-Ig and returns to its original specific value. When the drum current Id decreases below the specific value, on the other hand, reverse operation is performed and the grid current Ig decreases, so the drum current Id increases and returns to its original specific value.

IPC: H02K1/16
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To obtain a rotary electric machine which copes with the speedup and the promotion of large capacity and is highly efficient and economical and excellent in maintainability by forming a slit running in circumferential direction at the foot of each electric iron plate facing the gap of a rotary electric machine. SOLUTION: A circumferential slit 20 with a depth equivalent to the depth of the penetration of the pulsating magnetic flux is made at the foot facing the gap 18 of each electric iron plate 1 constituting a stacked rotor iron core 2. The mechanical influence by the existence of this slit 20 can be evaluated by the mechanical stress by working centrifugal force. But, since the rotor iron core 2 is at the section of high stress, the inside diameter difference of the iron core which decides the sectional area of the member concerned with the stress of the rotor iron core 2 amounts to several mm on one side actually, so even if a slit 20 with a depth of, for example, 1mm is made at the periphery, the difference with the case of no slit is only 1% or under, and this is an order which can be ignored utterly. Hereby, this can cope with speedup and promotion of large capacity, and this can have high performance and excellent economical efficiency and maintainability can be obtained.
