    摘要： For regenerating an exhaust gas particulate collecting filter, there is provided an exhaust gas particulate purifying process in which damage to the filter caused by a thermal action can be prevented and further electric power can be saved when an electric current supply to an electric heater attached to the filter is controlled. In the filter container (4), an electric heater (21) is provided on an end surface of the filter on an upstream side with respect to a regenerating gas flow, or provided at a position close to the end surface. Also, a temperature sensor (22) for measuring a temperature of the filter is provided inside the filter or at a position close to an end surface of the filter opposite to the aforementioned end surface. Further, there is provided a first controller (13) for determining an appropriate current amount to be supplied to the electric heater and also for determined an electric power reducing pattern used in the case of stoppage of power supply, in accordance With the filter preheating temperature immediately before the start of regeneration detected by the temperature sensor (22). A second controller ( 17) controls a current amount supplied to the electric heater (21) in accordance with a command given by the first controller (13).

    摘要： A filter for collecting fine particles in exhaust gas is equipped with: a multitude of cells bordering on each other and allowing exhaust gas to flow therethrough; cell partitions separating these multitude of cells from each other and having a multitude of pores through which the multitude of cells communicate with each other; and stop sections provided in the end portions of the multitude of cells so as to cause the exhaust gas introduced into each of the cells at one end thereof to flow into the adjacent cells through the pores of the cell partitions and be discharged at the other end of the cell. These stop sections are so arranged that the amount of exhaust gas entering the cells at the central region of one of the end portions is smaller than that at the peripheral region of the same. With this construction, the amount of fine particles accumulated in the peripheral filter region is relatively large, and that in the central filter region is relatively small. Thus, an increase in temperature occurs in the peripheral filter region, whereas it is suppressed in the central filter region, so that the difference in temperature between the two regions is kept at a low level, thereby effectively protecting the filter from damage.

    摘要： A porous support of the present invention comprises a laminate which is formed by laminating a corrugated sheet, in which high and low wave portions coexist, and a flat sheet, and which is wound into a spiral form. The porous support is particularly used as a catalyst support for purifying automobile exhaust gas. Appropriate combination of the high and the low wave portions in the corrugated sheet permits the selection of any one of various cross-sectional forms such as a conventional circular form, a race track-like form, a broad bean-like form, a triangular form and other suitable forms. The degree of freedom of the form can be thus increased.

    摘要： A swash plate type compressor has a rotary shaft, an inclined swash plate for rotation with the shaft, and a plurality of pistons connected to the swash plate. Each piston defines at both ends thereof a pair of working chambers. The piston reciprocates while being subjected to a swing motion concomitant with the rotation of the swash plate, to suck a fluid into the working chambers for compression. The swash plate is mounted on the shaft through a support unit which serves to selectively vary the inclination of the swash plate and shift the center of rotation of the swash plate along the shaft. The fluid is introduced from a suction passage through and around the swash plate to suction chambers formed adjacent the working chambers. A bypass passage is formed to directly communicate the suction passage with the suction chamber on one side of the shaft while bypassing the swash plate. When the inclination of the swash plate is decreased and the rotational center position thereof is shifted so that substantially no compression of fluid is completed in the working chambers on the one side of the shaft to decrease the displacement of the compressor, the fluid flows in the one side suction chamber through the bypass passage responsively to the flow of fluid toward another side working chambers to lubricate and cool sliding parts for the shaft.

    摘要： A multiple-turn scroll compressor has a first scroll member and a second scroll member. Each of the scroll members has a scroll blade which is engaged with the other. A shaft has an eccentric portion which supports the first scroll member. A cylindrical guide is provided rotatably on a housing and has a guide groove at one end. A slider fixed on the first scroll member engages with the guide groove and slides on it. Driving forces are transmitted from the shaft to the first scroll member through the eccentric portion. The first scroll member is prevented from rotating on its own axis by the engagement of the cylindrical guide and slider but not from orbiting.

    摘要： A variable displacement swash-plate type compressor suitable for use as a refrigerant compressor of an automotive air conditioner has a cylinder block having a plurality of cylinder bores each slidably receiving a double-headed piston, a shaft driven by an automotive engine, a swash plate tiltably mounted on the shaft for rotation therewith to reciprocatorily move the pistons, and a spool for moving the swash plate axially of the shaft and changing the angle of tilt of the swash plate. The swash plate and the shaft are connected in such a manner that, when the swash plate is axially moved while changing its tilting angle, the position of stroke end of each piston is changed only in a working chamber on one end of the piston, whereas no change in the position of the stroke end occurs in the other working chamber on the other end of the piston.
