IPC: C21D9/40
Filed: 1987-08-10
Abstract: PURPOSE:To improve strength of a trunnion by providing three journals on the outer diameter face of a boss member at intervals of 120 deg., and forming circular-arc thefts on an inner diameter face of the boss part, that is, on inner faces of cylindrical parts between journals. CONSTITUTION:Trunnion material A' is provided with a boss member 1 and three journals 2 formed on the outside thereof at intervals of 120 deg.. On the inner diameter face of the boss member 1, that is, inner faces of cylindrical members 4 between the journal forming portions, are formed thefts 5 which are circular arcs, narrowed gradually from the central parts toward both ends. The sizes of the thefts 5 approximately correspond to a contract amount of the cylindrical members 4 at the time of heating/cooling. In this arrangement, the inner diameter face 3 of the boss member 1 forms approximately an exact circle due to cooling after hardening of the trunnion material A'. A second shaft is then press-fitted inside the boss member 1 and thereby tensile stress is evenly applied to the whole inner diameter face of the boss member 1 to improve the strength of the trunnion.

IPC: H01L21/66
Filed: 1989-08-04
Abstract: PURPOSE:To surely detect a bonding defect by a method wherein, when it is electrically inspected whether a bonded state between a lead formed on a tape carrier and an electrode bonded to its end part is good or not, an external force is exerted on a bonded part of the lead and the electrode in a direction in which they are separated mutually. CONSTITUTION:A tape carrier 1 is positioned in a prescribed position by using a positioning pin 8; the tip of a probe 10a is brought into contact with a test pad 4b of a lead 4 as an inspection object; a push-up pin 9b is moved upward to push up the tape carrier 1 from its rear side. Thereby, an external force is exerted on bonded parts of inner leads 4a and bump electrodes 7 in a direction in which they are separated mutually. When a bonded state of the inner lead parts 4a and the bump electrodes 6 as inspection objects is not sufficient, the bonded parts of the inner lead parts 4a and the bump electrodes 6 are in a noncontact state or in a state close to it by the external force. As a result, a resistance characteristic straight line of a defective product level is obtained at a continuity check circuit; an abnormality in the bonded state can be confirmed.
