Title: Metal honeycomb catalyst
Inventor: NIIZAWA MOTOHIRO
IPC: B01J35/04
Filed: 1990-06-14
Abstract: PURPOSE:To enhance the reducing efficiency of a particulate by a method wherein a large number of cells mutually extending in parallel across thin walls by thin metal plates and coating the surfaces of the walls with a catalyst and providing a large number of small recessed parts to the surfaces of the walls. CONSTITUTION:Small recessed parts 5 are formed on the surface of the walls of flat plates 3 and corrugated plates 4 and a gas streams are disturbed to form a large number of small gas streams colliding with the recessed parts 5. Therefore, the dry soot in gas is bonded to the recessed parts 5 to be collected in a certain degree. When the number of cells per a unit area of outer peripheral parts 12 become more than those of inner peripheral parts 13 in respective layers wound in a multiple state, the exhaust temp. of the outer peripheral parts 12 becomes lower than that of the inner peripheral parts 13 by radiation and the catalitic reaction effect of the outer peripheral parts 12 becomes lower than that of the inner peripheral parts, and much gas flows through the inner peripheral parts 13 and catalytic reaction effect is enhanced. The contact efficiency of the gas and the catalyst becomes high even in the outer peripheral parts 12 and catalytic reaction advances in the same degree as the inner peripheral parts. As a result, catalytic reaction effect is enhanced as a whole and, therefore, a particulate can further be reduced.

Title: Discriminating system for defect of cutting end surface in optical fiber cutting method
Inventor: KOKAYU MIKIO
IPC: G02B6/25
Filed: 1978-12-18
Abstract: PURPOSE:To discriminate a defective of a cutting surface of a optical-fiber automatically and efficiently, by detecting the change of the load of a movable portion, the time required for cutting, etc. in the case when a rift is formed at a fixed location of the optical-fiber and cut by applying load to the movable portion. CONSTITUTION:An optical-fiber 26 is arranged extending over a fixing portion 1 and a movable portion 2 and settled by means of clamps 3, 4 and a rift is made up by means of a cutting tool 24. A shaft 10 is rotated, the movable portion 2 is provided with tension in the arrow head direction A and an end portion 27 of the optical-fiber 26 is cut. When the end portion of the optical-fiber 26 is cut before the angular displacement theta1 or after the theta2 of a contact switching cam 11 at that time, impulses are not generated in a circuit 23 because a contact 18 contacts with an insulator portion 14 of the contact switching cam 11. Consequently, a decision circuit 19 puts a relay contact 20 under an opening conditon, does not light up an annunciator 21 and indicates the defect of cutting. Thus, the non-defective or defective of a cutting surface can automatically be discriminated.
