    摘要: An exhaust gas purifier, having three or more filter units parallel, wherein if at least one filter unit fails during its generation, it is compensated by the cyclic operation of the maining filter units so that the total function of the exhaust gas purifier is practically maintained. Electric heaters 14 are provided for regenerating individual filter units 3, and valves 4 are placed either at the entrances or at the exits of the units 3. While filter units 3 with opened valves 4 trap particulates, at least one filter unit 3's valve 4 is closed to send an electric current into the heater 14 for regenerating the filter unit 3. If the detected current is beyond a predetermined range, the current supply is shut off with the valve 4 still kept closed, and another filter unit 3 is regenerated in the same manner.

    摘要: An object is to provide a particulate trap for a diesel engine which can efficiently burn particulates trapped by a filter while supplying oxygen by natural convection so that the filter can be regenerated in a short time while minimizing the power consumed by the heater. To accomplish this purpose, end plates 6, 7 and brackets 9 may be welded to compressed portions 4a, 5a of an inner cylinder 4 and an outer cylinder 5; heater-supporting ceramic insulators are mounted, spaced from each other, on a heater 14; and/or an ambient air introducing passage 36 is provided to extend from outside the case into a multiple-cylinder filter provided in the case.

    摘要: A composite bearing structure that has a high rotational accuracy and that can withstand high-speed rotation comprises first bearing means, second bearing means, third bearing means and fourth bearing means. The first bearing means supports a radial impact force which is applied to a rotator during rotation, and is formed by an inner ring (1) and an outer ring (2) consisting of silicon nitride ceramics sintered bodies. The second bearing means supports an axial load which is applied to the rotator while maintaining a prescribed clearance with the rotator, and is formed by a magnetic bearing body of two permanent magnets (12) and (13) which are thrust-directionally opposed to each other. The third bearing means maintains the radial rotational accuracy of the rotator, and is formed by a radial dynamic pressure producing groove (5) which is formed in a cylindrical surface of the inner ring (1). The fourth bearing means maintains the thrust-directional rotational accuracy of the rotator, and is formed by an air dome portion (100) which is confined in a semi-closed state by the inner ring (1), the outer ring (2) and a cover (4).

    摘要: A slide member has a sliding surface made of ceramic and has a surface roughness of not more than 1.0 .mu.m in center line average roughness Ra. ceramic includes a silicon nitride sintered body, which contains crystal grains having a linear density of at least 35 per 30 .mu.m in length with a boundary phase volume ratio of not more than 15 volume %, and which contains pores of not more than 20 .mu.m in maximum diameter in a content of not more than 3%. In a method of manufacturing the slide member, it is possible to ensure smoothness of the sliding surface by grinding the sliding surface and thereafter heating the ceramic in either inert gas or an atmospheric air. A slide member that can be used under severe sliding conditions of high-speed sliding or the like and that has excellent wear resistance is obtained. Even if the slide member is used for a sliding part of a compressor or the like which employs a fluorocarbon containing no chlorine as a cooling medium, it is possible to prevent the occurrence of seizure and abnormal wear on the sliding surface.
