Title: Ozone decomposing device
Inventor: SHIMAMUNE TAKAYUKI
IPC: B01D53/86
Filed: 1990-07-12
Abstract: PURPOSE:To almost completely decompose the ozone in an ozonecontg. gas, to discharge the gas and to prevent secondary pollution by separating plural housings from one another with a partition having a hole in the ozone decomposing device consisting of plural housings contg. catalyst. CONSTITUTION:An ozone-contg. gas supplied to the ozone decomposing device from its lower side is allowed to ascend in the vertical hole of a catalyst 3 in the lower housing 2 and between the catalyst 3 and the inner wall of the housing 2 as shown by the arrow, brought into contact with the surface of the vertical hole of the catalyst 3 and its outer surface, decomposed and sent to the lower surface of a partition 4. When the ozone-contg. gas is not horizontally moved, the gas reaches the partition 4 without a part of the gas being brought into contact with the surface of the catalyst 3. The ozone-contg. gas is then allowed to collide with the partition 4, turned inward, introduced into the upper housing 1 from the circular hole 5 at the center as a turbulent flow and allowed to ascend just as in the housing 2, and the ozone is further decomposed. The ozone undecomposed in the housing 2 is mostly decomposed in the housing 1 owing to the change of its course. Saturate steam is condensed on the partition 4 and not introduced into the housing 1.

Abstract: PURPOSE:To hold an effective refractive index just under a stripe at a sufficiently large value without damaging the confinement of currents, and to control a mode by bringing a layer having a high refractive index near to an active layer having a high refractive index near to an active layer in the stripe. CONSTITUTION:A curve represents a curve obtained by theoretically calculating stripe width W in which a primary mode is cut off to an effective refractive index DELTAneff. A stable fundamental transverse mode is acquired extending over high-output operation of 30mW or more after a low output by setting DELTAneff to 6X10<-3> or more and bringing W to 20mum or less. When DELTAneff reaches 1X10<-1> or more, on the other hand, stripe width in which the primary mode is cut off reaches 0.5mum or less, and not only processes are made difficult on the preparation of an element but also mode size is scaled down, thus lowering an optical output level where deterioration due to the breakdown of an end surface is generated, then resulting in making high-output operation to be ena bled.
