The utility model discloses a wheel hub cover which is provided with an annular plane and a plurality of through holes, and the through holes penetrate through the annular plane. The at least one first protrusion is connected to the annular plane, protrudes out of the annular plane and is used for making contact with the sealing gasket and pressing the sealing gasket tightly; the first protrusion is provided with a starting end and an ending end and extends from the starting end along the annular plane, and when extending, the first protrusion avoids the through hole till the ending end intersects with the starting end and is in seamless connection with the starting end, and a closed surrounding structure is formed. The area size of the first bulge is smaller than that of the annular plane; therefore, the technical problems that the fastening force borne by the hub cover is relatively large, the hub cover is broken, and the service life is shortened are solved.

The invention discloses a multifunctional cap opener for a biological experiment, which is adaptive to opening and closing requirements of an EP tube, a centrifugal tube, a reagent bottle and a PCR (Polymerase Chain Reaction) row tube by integrating a slit, a notch, a gradually-changed groove and an arch-shaped edge structure. The design of the asymmetric tooth-shaped protrusions and the lever is adopted, the operation intensity is remarkably reduced, and the light weight (smaller than 70 g) and the low cost are achieved by combining the hollowed-out part and the ergonomic holding part. The tool is suitable for high-flux experiment scenes.

An absorption core is arranged on the surface of the upper end of a nursing pad body, spill-proof assemblies are arranged on the left side and the right side of the nursing pad body, first waist attaching cloth is arranged at the rear end of the nursing pad body, and second waist attaching cloth is arranged at the front end of the nursing pad body. Elastic cooling mechanisms and fixing assemblies are arranged on the first waist attaching cloth and the second waist attaching cloth respectively, an adjusting assembly is arranged on the first waist attaching cloth, the elastic wrinkle covered edges are arranged on the left side and the right side of the nursing pad body, and an annular flow guide groove is formed in the periphery of the absorption core; side leakage prevention raised lines are arranged between the annular flow guide groove and the elastic wrinkle covered edge and comprise a front inclined raised line and a rear inclined raised line, the front inclined raised line and the rear inclined raised line both incline towards the middle of the nursing pad body, and one ends of the front inclined raised line and the rear inclined raised line are fixedly connected; the absorption core can inhibit bacteria and remove odor, the anti-overflow assembly prevents side leakage of the nursing pad body, and the elastic cooling mechanism can achieve a good cooling effect.

The present invention relates to a method in which a CPU of a control device executes: a specific cylinder fuel cut-off process to stop the fuel supply to a part of a plurality of cylinders and continue the fuel supply to the remaining cylinders to operate an internal combustion engine; and a fastening force reduction process to reduce the fastening force of a lockup clutch of a torque converter. When the CPU executes the specific cylinder fuel cut-off process under a condition in which the internal combustion engine is operating under load, the specific cylinder fuel cut-off process is started in a state in which the fastening force is reduced by the fastening force reduction process.
