A method for facilitating receiver stack level control, comprising the steps of: generating a primary increment initiated by a switch indicative of the receiver stack level; generating a secondary increment operative to compensate for incomplete adjustment of the receiver stack level by the primary increment. 18. The method of claim 17, wherein the secondary increment is generated by a software means. 19. The method of claim 17, wherein the primary increment includes generating an additional increment when it is necessary to ensure the receiver stack level maintains a proper level. 20. A method for facilitating receiver stack level control, comprising the steps of: generating a primary increment initiated by a switch indicative of the receiver stack level; generating a secondary increment not initiated by the switch and operative to compensate for incomplete adjustment of the receiver stack level by the primary increment. aces meet with said outer circumferential surface; and if ion-plating a hard ceramic deposition layer on the diffusion layer. 8. The piston ring of claim 7, wherein, in the chamfered corner regions the diffusion layer is completely removed to expose the stainless steel base material, at its upper and lower corners. 9. The piston ring of claim 7, wherein in the chamfered corner regions the thickness of the diffusion layer is reduced to 30% or less. 10. The piston ring of claim 7, wherein the thickness of the diffusion layer disposed beneath the ion-plating deposition layer is substantially constant except at the chamfered corner regions.
