Patent number: 5059076Abstract: A structure for preventing from readjusting an adjustment member, which adjusts an extent of operation by rotating the adjustment member, and more particularly, for preventing from readjusting an adjustment member in a carburetor. The structure for the adjustment member includes a hollow tube of a heat shrinkable resin to be fitted around the outer surface of a rotating operational portion of the adjustment member in such a manner that when the hollow tube is heated to be shrunk, it is securely fixed around the outer surface of the adjustment operational portion. Owing to such an arrangement, it will be impossible to fit a tool or the like onto the adjustment operational portion of the adjustment member once it has been available to the user, thus preventing the readjustment. Even if it is readjusted, the readjustment will be easily recognized during a particular inspection of performance.Type: GrantFiled: June 28, 1990Date of Patent: October 22, 1991Assignee: Aisan Kogyo Kabushiki KaishaInventor: Yutaka Kondo

Patent number: 4275285Abstract: A steel nut body has its wrench flats covered by a sheet stainless steel sheath that extends over one of the nut ends to form a cap. The surfaces of the wrench flats are formed with ridges that bear against the inner surfaces of the sheath. The sheath is welded to the nut to resist forces exerted during torquing by bringing a pair of electrodes into pressured contact with the sheath on opposed sides of the nut to produce pressure concentrations at the ridges. An extremely short, high current electrical pulse is then passed between the electrodes. The heating produced by the current at the interface between the sheath and the nut body decreases the electrical resistance of this path resulting in primary current flow path between the two interfaces, through the nut body, to produce resistance welds at the inner faces without substantially modifying the metallurgy of the sheath.Type: GrantFiled: July 25, 1979Date of Patent: June 23, 1981Assignee: Towne Robinson Fastener CompanyInventor: Albert A.
