摘要:
An object is to avoid generation of a collision sound of a second vane of a compression system comprising a multicylinder rotary compressor being configured to be used by switching of a first operation mode in which both rotary compression elements perform a compression work and a the second operation mode in which the only first rotary compression element substantially performs the compression work. When the second operation mode is switched to the first operation mode, discharge-side pressures of both the rotary compression elements are applied as a back pressure of the second vane, and thereafter an intermediate pressure is applied which is between suction-side and discharge-side pressures of both the rotary compression elements. When the first operation mode is switched to the second operation mode, a valve device interrupts flowing of a refrigerant into a second cylinder, and thereafter suction-side pressures of both the rotary compression elements are applied as the back pressure of the second vane.

A seal assembly has simple assembly structures, and provides secure sealing effects. A crawler-track connection structure allows the seal assembly to be easily mounted, and securely prevents overflow of a lubricant and the like to the outside. A pair of seal rings (1) and (1) individually having lip portions (23) and (23) are disposed such that each of the lip portions (23) and (23) protrudes in a direction opposing an axial direction, and a load seal ring (2) is compressed and inserted between the pair of seal rings (1) and (1). The load seal ring (2) exerts reaction forces on the pair of lip portions (23) and (23) outwardly in the axial direction.

An exhaust emission control system for an internal combustion engine, having a nitrogen oxide removing device provided in an exhaust system of said engine for absorbing nitrogen oxide contained in exhaust gases in an exhaust lean condition. An amount of change per unit time in the sulfur oxide amount absorbed in the nitrogen oxide removing device is estimated according to the air-fuel ratio of an air-fuel mixture supplied to said engine and the operating condition of said engine. The estimated amount of change is accumulated to thereby estimate the sulfur oxide amount absorbed in the nitrogen oxide removing device. The sulfur oxide is removed from the nitrogen oxide removing device when the estimated sulfur oxide amount has reached a set value.

A method for manufacturing a multilayer ceramic electronic element includes the steps of forming ceramic green sheets having superior surface smoothness and small variations in thickness at a high speed, in which defects such as pinholes are prevented from occurring, and providing internal electrodes and step-smoothing ceramic paste on the ceramic green sheets with high accuracy. The method includes the steps of applying ceramic slurry to a base film by a die coater followed by drying performed in a drying furnace for forming the ceramic green sheets, and performing gravure printing of conductive paste and ceramic paste onto the ceramic green sheets by using a first and a second gravure printing apparatus, respectively. Accordingly, the internal electrodes are formed, and the step-smoothing ceramic paste is provided in regions other than those in which the internal electrodes are formed.

A toner suitable for use in electrophotography, etc., is composed of toner particles each containing a binder resin, a colorant and a wax component. The toner has a number-average particle size of 2-6 &mgr;m and a standard deviation in particle size of below 2.6 &mgr;m based on a number-basis distribution of circle-equivalent diameters, an average circularity of 0.970-0.995 and a standard deviation in circularity of below 0.030 based on a circularity frequency distribution, and a residual monomer content of at most 500 ppm. The toner particles have such a microtexture as to provide a particle cross section as observed through a transmission electron microscope (TEM) exhibiting a matrix of the binder resin and a particle of the wax dispersed in a discrete form in the matrix of the binder resin.

An object of the present invention is to provide a multi-cylinder rotary compressor which can enhance the reliability by improving the compression efficiency/mechanical efficiency. The bearings are fixed on the inner wall of the closed container, the cylinders are fixed to the bearings, and a gap is formed between the respective cylinders and the inner wall of the closed container. The design with the relatively large internal volume of the closed container is possible, and the reliability can be enhanced. Further, improvement in the compression efficiency and the mechanical efficiency can be achieved with the compact multi-cylinder rotary compression element.
摘要:
A pressure receiving surface (8) having a diameter gradually decreasing in an axially inward direction is formed at an outer end portion of a pin (1), whereas a pressing portion (7) is formed at a circumferential edge of an opening of a pin insertion hole (5) of a link (2). A retaining ring (3) is formed with a friction surface (9) to be press-contacted to the pressure receiving surface (8) when a force is applied from the pressing portion (7) upon development of a relative movement in a disengaging direction. The retaining ring (3) and the pressure receiving surface (8) share a greater area of contact than in the prior art, providing sufficient friction. This makes possible to provide a fastening structure of the link and the pin of a crawler belt which can be assembled by simple operation at a low cost, without requiring a high machining accuracy, and thus can be manufactured at a low cost.
