Title: Optical circuit switch made of silica
Inventor: MARCUSE DIETRICH
IPC: G02F1/335
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To provide an optical circuit switch made of slica having a small-sized waveguide structure so as to facilitate the routing of optical signals using an acoustooptical effect. SOLUTION: When an elastic surface wave 125 is not generated, an optical signal from an input part 100 is propagated in an even transmission mode to a first output part 110 via a multimode part 105 by a coupler waveguide structure. However, when a SAW source turns the elastic surface wave to the multimode waveguide part 105 with a specific phase matching angle θ, the optical signal entering to the input part 100 is coupled from the first transmission mode to a second transmission mode in the multimode part 105 and as the result, this power is transferred in the second transmission mode. Then, the optical signal of the second transmission mode is received at the inside of a second output part 115.

Title: Catalytic reactor
Inventor: ARASHI NORIO
IPC: B01J8/02
Filed: 1979-09-21
Abstract: PURPOSE: A catalytic reactor in which neither the biassed flow of gas nor the increase in ventilation loss takes place.  
     CONSTITUTION: In the catalyst-packed layer 2, a plurality of rectifying plates 5 are provided vertically and along in the direction of gas flow, having a V-shaped tip portion whose wide part is the gas inlet 3 side and whose narrow part is the gas outlet 4 side. Thus, in the reactor 1 provided with the rectifying plates 5 in such a solid manner in its narrow space, the biassed flow of gas can be eliminated and hence the performance of the reactor can be raised, and at the same time, because dust can be removed from gas before the inflow of gas into the catalyst-packed layer 2, in case where gas to be treated contains dust, the increase in the ventilation loss in the catalyst-packed layer 2 can be suppressed to the greatest extent.

Title: Exposure device of electrophotographic copier
Inventor: YOKOYAMA YASUMASA
IPC: G03G15/04
Filed: 1978-10-05
Abstract: PURPOSE: To prevent the displacement of the elastic material belt itself and achieve the improvement in the resolving power of images by so constituting the device that the speed of feed rollers is made slightly slower than the conveying speed of the belt and becomes equal when the photoreceptor is attracted to the elastic belt.  
     CONSTITUTION: The peripheral speed of feed rollers 15 is set at the speed slightly slower than the peripheral speed of an elastic belt 20 so that a photoreceptor 11 is prevented from floating on an elastic material belt 20. Hence, when the photoreceptor 11 advances while being attracted onto the elastic material belt 20, the conveying speed of the photoreceptor 11 becomes faster than the peripheral speed of the feed rollers 15. As a result, the feed rollers 15 become free to a sprocket 27 owing to the action of one-way clutch 29 and their speed becomes equal to the conveying speed of the photoreceptor 11. Since in this way the force for extending the elastic material belt 20 does not occur at the time when the elastic material belt 20 has stopped and therefore, displacing of the elastic material belt 20 after stopping does not occur and the occurrence of out-of-focus phenomenon may be prevented.
