The die stage part 3 is formed in such a way that a difference in level is formed with reference to the inner lead parts 4 and tie bars 6, 6'. A semiconductor element 9 is mounted on the die stage part 3; its electrodes and the inner lead parts 4 are connected by using wires 10; after that, this assembly is molded and sealed by using a resin 11 so as to wrap the die stage part 3 and the inner lead parts 4. After that, individual tie bars 2, 2', 7, 7', 8, 8' are cut and removed; in addition, outer lead parts 5 are bent and shaped. Thereby, heat generated at the semiconductor element 9 is dissipated to the outside of a package; the window parts 12 enhance a close contact force because they are connected to resins on the surface and the rear.

Title: Printing method of ink jet printer
Inventor: KONDO NORIMASA
IPC: B41J2/51
Filed: 1995-07-21
Abstract: PROBLEM TO BE SOLVED: To obtain a printed matter printed with excellent printing performance without wasting ink and time by excessive purging by a method wherein the sub-scanning directional pitch of nozzles is set to be 2 times as much as the pitch of printing resolution and printing is performed by using all the nozzles and only even-number row nozzles or odd-number row nozzles. SOLUTION: Numbers n1 , n2 , n3 ...nz are allotted to nozzles 10. The vertical dot pitch of the nozzles is set to be 2 times as much as their printing dot pitch. For example, when a nozzle nz among the nozzles is under faulty state, printing is performed by using odd number row nozzles as printing nozzles. Concretely, during the sliding of a carriage 12 along shafts 13a and 13b, ink liquid drops are jetted against paper 22 only from the odd number row nozzles and then the paper 22 is fed with a motor 17 by the predetermined printing resolution pitch. Then, printing is performed again with ink drops jetted from the odd number row nozzles. Thus, even if a nozzle, the printing quality of which is inferior, is generated, the printing can be performed without employing the group, to which the inferior nozzle belongs, resulting in realizing highly reliable printing.
