Abstract: A method of manufacturing a connecting rod for a piston engine in which the inner surface of the small hole of the connecting rod is milled to produce a multifaceted surface which includes two deep spot faces along each edge of the small hole and two tapered faces. This milling step yields thin edge regions along each edge of the small hole to serve as a process reference hole with process reference planes. The final step, according to the method of this invention, is to remove the thin edge regions with a rotating cutting tool, thus exposing the tapered faces to serve as chamfered edges without any significant production of burs or distortion of the connecting rod.

Abstract: The present invention reveals a method for enzymatically inactivating a target DNA, a method for detecting conformational change in a nucleic acid, and a method for detecting the presence of a target DNA molecule. The method for enzymatically inactivating a target DNA involves preparing a plasmid, phage, virus, or any other delivery vehicle such as a liposome containing a gene encoding a nuclease. The delivery vehicle is then delivered into cells. The cells are induced to produce the nuclease and the target DNA is then enzymatically inactivated. Alternatively, the nuclease protein is delivered directly to cells and used to enzymatically inactivate the target DNA. The method for detecting conformational change in a nucleic acid requires contacting a nucleic acid with a hybrid restriction nuclease, determining whether the hybrid restriction nuclease has interacted with the nucleic acid, and detecting the conformational change in the nucleic acid.

Abstract: An antidiffusion layer is provided between a first fuel adsorption layer communicated with a fuel tank and a second fuel adsorption layer communicated with air. Since adsorbing ability of the antidiffusion layer is lower than that of the first and second fuel adsorption layers, pore diffusion of the fuel vapor from the first fuel adsorption layer to the second fuel adsorption layer is reduced. Since the antidiffusion layer forms a plurality of nonlinear passages, air diffusion of the fuel vapor is reduced. Therefore, the diffusion of the fuel vapor is suppressed with a thin, small and simple antidiffusion layer, and the canister can be simplified and the reduction of the number of parts and the cost thereof can be realized.
