Filed: 1984-05-30
Abstract: PURPOSE:To decrease considerably the number of steps by having a stage for dipping magnetic heads together with a grinding jig into a plating layer and subjecting the heads to the plating treatment and a stage for grinding the heads while lifting jigs are held attached to the grinding jig after the plating treatment. CONSTITUTION:The surfaces of the magnetic heads H... for sliding with a recording medium are ground after removal of a mask. The grinding jig 6 which is held attached with the lifting jigs 7a, 7b is set to the grinding device and the copper-plated surfaces of the heads for sliding with the recording medium are ground. The silicone mask 10 is again formed thereon after the grinding and the mask material on the surfaces for sliding with the recording medium is removed; thereafter the surfaces are subjected to the hard chrome plating. The heads H... are finally set to the grinding device by the grinding jig 6 attached with the lifting jigs and the hard chrome plating surfaces are ground. The grinding jig and lifting jigs are thus held attached during the masking operation, plating treatment and grinding operation and therefore the labor for replacing the jigs is eliminated and the number of steps is considerably decreased.

Filed: 1995-05-08
Abstract: PURPOSE: To exhibit satisfactory tamper evidence, by making the cut strength of at least one of a plurality of bridges lower than that of the others, thereby reducing an angle at which each bridge is cut in a capped container. CONSTITUTION: In a cap 50, 16 plate-like leaders 55a are arranged apart from one another in a circumferential direction, on a border between a main part 57 and TE-ring 58. Parts of the leaders 55a are cut by a horizontal score 56 and their uncut parts serve as bridges 55(X) and 55(Y). The cut strength of the bridge 55(X) is greater than that of the bridge 55(Y). A container mouth has four lock claws arranged with certain amounts of space between them, and the cap 50 has many lock projections 60 on the internal wall of its TE-ring 58, therefore the bridges 55(X) and 55(Y) are cut at the small angle of turning. Therefore, this reduces an angle at which each bridge is cut.
