Abstract: PURPOSE:To prevent a break by providing the surroundings of an opening section of a film with a plurality of notches so that, when an inner lead is bonded, a film that supports the inner lead will be deformed and bended on the opening section provided on the mounting section of a chip. CONSTITUTION:A circuit board for a film carrier is made of a polyimide film 20, with a feed hole 13 formed on the both sides. A lead group 6 is formed on a film region 3 where wiring is to be formed, these leads are connected to an electrode pad mounted on an opening section 2 formed on the center of the region. The electrode pad and the lead are connected with a bump electrode. A notch section 12 is formed on the film which supports the leads on the four corners of the opening section 2.

Title: Retriggerable single stable multivibrator
Inventor: BADEIMU BORISU MINUHIN
IPC: H03K3/033
Filed: 1988-09-29
Abstract: PURPOSE: To improve the reliability by making a propagation chain circuit respond to the output of a bistable device, propagate a signal giving a reset pulse after a predetermined delay time, and further respond to an input pulse and stopping the propagation of the reset pulse. CONSTITUTION: Respective AND gates 20 of the propagation chain circuit 16 operate as delay circuits to expand output pulse width. A pulse edge detecting and pulse generating circuit 10 detects respective edges 30 of the input signal (a) and generates pulses 32 having short width shown by a waveform (b). The respective pulses of this waveform (b) set a latch device 1 to a true state unless a circuit is already in the for-true state, thereby raising the signal with the waveform (c) to a high level. At the same time, the respective pulses with the waveform (b) are inverted by an inverter 14 to generate a waveform (e). According to the high-level state of the waveform (c) applied to one input of an OR gate 18, its output signal waveform (d) is shifted to the high level.  At the same time, the signal with the waveform (c) begins to be propagated through the propagation chain circuit 16 consisting of the AND gates 20.
