Title: Test circuit for semiconductor integrated circuit
Inventor: KUSABA KAZUYUKI
IPC: G01R31/26
Filed: 1991-06-29
Abstract: PURPOSE:To perform open short checks on a plurality of external terminals in a short time by finding the AND and OR of signals inputted to the external terminals and calculating the OR of the AND and inverted signal of the found OR. CONSTITUTION:When '1' is given, for example, to a plurality of external terminals 1-5 from a tester, the output of an AND circuit 6 becomes '1' and a latch 8 holds '1'. When '1' is given to the terminals l-5, the output of a NOR circuit 7 becomes '0' and a latch 9 holds. As a result, the output of an OR circuit 10 becomes '1'. When '1' is given as a test input signal in such state, a test signal 1 is outputted from an AND circuit 11. In case at least one terminal short-circuits with a grounding line in an IC or is not connected to the pad of a semiconductor chip due to defecting bonding, the outputs of both circuits 6 and 10 become '0'. Therefore, the test signal 1 is not outputted from the circuit 11 and the defective bonding can be detected.

Title: Air-fuel ratio control device for internal combustion engine
Inventor: TAKESHIMA SHINICHI
IPC: F02D21/08
Filed: 1989-07-20
Abstract: PURPOSE:To increase HC, which is effective for reduction of NOx, so as to decrease NOx emission by controlling air-fuel ratio to slightly a rich side with introduction of EGR, in the case of exhaust gas at a high temperature. CONSTITUTION:A lean operative condition discriminating means discriminates whether an operation is a lean operative condition or not in accordance with an engine operative condition parameter, for instance, cooling water temperature, while an exhaust gas temperature discriminating means discriminates whether or not an exhaust gas temperature is a predetermined value, for instance, 600 deg.C or more. When an engine is in a lean operative condition with the exhaust gas temperature less than the predetermined value, the first air-fuel ratio adjusting means adjusts air-fuel ratio to the first lean air-fuel ratio, and when the engine is in the lean operative condition with the exhaust gas temperature in not less than the predetermined value, the second lean air-fuel ratio adjusting means adjusts the air-fuel ratio to the second air-fuel ratio in a rich side from the first air-fuel ratio. While when the engine is in the lean operative condition with the exhaust gas temperature not less than the predetermined value, an EGR-on means turns on an EGR valve 11. Thus, NOx emission can be reduced.
