Title: Manufacture of resin-sealed semiconductor device
Inventor: YOKOYAMA TAKAAKI
IPC: H01L23/50
Filed: 1991-07-26
Abstract: PURPOSE:To make tensile rupture easy in a narrow strip 13 and to suppress the damage to a resin and a semiconductor chip to a minimum in the method of manufacturing a resin-sealed semiconductor device. CONSTITUTION:A lead frame 1 in which small cross-section parts 17, 18 for narrow-strip rupture use have been formed in narrow strips 12, 13 and in which holes 27 for stress relaxation use have been formed between the small cross-section parts 17, 18 and a semiconductor chip 2 is prepared. After the lead frame 2 has been mounted on a metal mold 19, a resin for sealing use is pressed into a cavity 22 in the metal mold 19. After the resin for sealing use has been solidified, the lead frame 1 is taken out from the metal mold 19, a tensile force is exerted on the narrow strips 12, 13 and the narrow strips 12, 13 are ruptured at the small cross-section parts 17, 18. When a tensile stress is exerted on minimum cross-section parts 17a, 18a in a concentrated manner, the narrow strips 12, 13 can be tensile-ruptured easily. A deformation force which is transmitted to a support plate 3 is relaxed by the holes 27 during their tensile rupture operation. As a result, a deformation force which is transmitted to the semiconductor chip 2 is reduced remarkably.

Title: Printer
Inventor: ODA AKIRA
IPC: B41J19/18
Filed: 1993-07-29
Abstract: PURPOSE:To prevent a continuous printing causing missing of printing from occurring by providing a discriminating means for discriminating whether a printing timing signal is made and outputted every preset time. CONSTITUTION:A discriminating means judges whether a printing timing signal C.PLS is inputted every time when an elapse time Ti becomes equal to or larger than a set time Ts (YES in ST10). If the presence of the signal input is judged (YES in ST11), a CPU clears a timer (ST12). If the absence of the signal input is discriminated (NO in ST11), a signal making stop control means functions to stop a printing timing signal generation operation of a printing timing signal generation means (ST13). At that time, the CPU outputs a clear signal and simultaneously transmits a signal, to a driver to instruct a display device to display to the effect that a printing is stopped by an abnormality of an encoder (ST14).
