    • A brake structure of a traction machine includes a brake drum which is made rotatable about a shaft disposed on a rotary axis of the traction machine, and an electromagnetic brake unit built in an inner space of the brake drum. The electromagnetic brake unit includes a plurality of movable iron cores, a plurality of brake shoes located on the outside of the individual movable iron cores and joined thereto by connecting members, the brake shoes having curved outer surfaces facing a curved inner surface of the brake drum, and a one-piece formed stationary iron core block. The one-piece formed stationary iron core block has a plurality of stationary iron core portions joined to the individual movable iron cores via compression springs for forcing the individual brake shoes against the curved inner surface of the brake drum via the movable iron cores and the connecting members.

    • An exhaust emission control system for an internal combustion engine having nitrogen oxides removing device provided in an exhaust system of the engine for removing nitrogen oxides in exhaust gases and an oxygen concentration sensor provided downstream of the nitrogen oxides removing device for detecting the concentration of oxygen in the exhaust gases. Deterioration of the nitrogen oxides removing device is determined on the basis of an output of the oxygen concentration sensor after the air-fuel ratio has been changed from the lean region to a rich region with respect to the stoichiometric ratio. Abnormality of the oxygen concentration sensor is determined on the basis of an output of the oxygen concentration sensor during a period in which the air-fuel ratio is kept in the rich region with respect to the stoichiometric ratio immediately after execution of the deterioration determination of the nitrogen oxides removing device.

    • A method for manufacturing a mirror surface tube for a photosensitive drum of a copying machine or the like, by which an external surface of an aluminium or aluminium alloy tube can be mirror-processed with high accuracy without surface defects, and in such a way that good quality required for a photosensitive drum is ensured and dimension accuracy, such as roundness, and production yield is improved involves a first step in which an aluminium or aluminium alloy tube, finished in a predetermined shape and dimension with surface roughness of 10 microns or less, is processed by a centerless grinding process. Then, in a second step, a grinding process is performed using an electrolytic integrated polishing apparatus including a tool electrode mechanism having an elastic grindstone so as to make a mirror surface tube having the surface roughness of 2.0 microns or less. Further, preferably, in a third stage, a roller burnishing process is performed to finish the tube to a surface roughness of 0.5 microns or less.
