Title: Ceramic package
Inventor: YAMAKAWA KOJI
IPC: H01L21/82
Filed: 1992-06-04
Abstract: PURPOSE:To form a ceramic package capable of dealing with a high density wiring used for a large power LSI package by disposing a plurality of lines of the electric pads on the same flat plane around a semiconductor device mounting part. CONSTITUTION:An LSI 13 is mounted on the upper surface of a ceramic substrate 10, and is connected with electrode pads 15 (inside electrode pad) and 16 (outside electrode pad) disposed into two lines through a wire 14. The electrode pad 15 is used for signal wiring, and the electrode pad 16 is used for power supply wiring and for ground wiring. Since the two lines of the electrode pads are disposed on the same flat plane these electrode pads can be formed even in a thin film process which uses a mask, and can satisfactorily deal with high density wiring. Further, the power supply and ground wiring electrode pads are made larger in their sizes by disposing them into two lines, and hence wiring characters cart be made thick and short to reduce inductance between the power supply and ground wirings and further increase the pitch of an internal wiring.

IPC: G07G1/14
Filed: 1984-07-13
Abstract: PURPOSE:To improve the actual efficiency of a communication line by allowing a master unit to give a temporary identification code effective only at corresponding logical coupling and using the temporary identification code as an address at communication when each slave unit establishes logical coupling with the master unit. CONSTITUTION:When the master unit receives a start-out request packet, the unit finds out the tempoary identification code not in use for the point of time, corresponds it to a specific identification code received just now and then transmits a start-out response packet 21 representing the correspondence between identification codes after the communication line becomes idle. Each slave unit references a control code and when it is a start-out response, if the own unit does not await the start-out response, it packet is disregard. In case of response waiting, the specific identification code of the informatio itself is looked for. If it is coincident with the own specific identification code, the succeeding temporary identification code is fetched and the temporary identification code is used for the succeeding communication.

Title: Air-fuel ratio control device for engine
Inventor: ARIMA MANABU
IPC: F02D41/00
Filed: 1983-08-05
Abstract: PURPOSE:To control the air-fuel ratio properly at all times regardless of the variation of exhaust gas temperature, by controlling the air-fuel ratio in accordance with the exhaust gas composition by the output of an O2 sensor and at the same time by changing the control value corresponding to the variation of the exhaust gas temperature. CONSTITUTION:When an engine is operated, the rotational speed of the engine is calculated from an ignition signal 12 in a control circuit 5 and when a cooling water temperature signal 13 is above a prescribed value, the suction negative pressure detected by a suction sensor 7 is below a prescribed value, and the rotational speed of the engine is less than a prescribed value, a feedback control of the air-fuel ratio is carried out on the basis of the output of an O2 sensor 4. In other words, the fundamental fuel injection quantity calculated from the suction negative pressure and the cooling water temperature is corrected by a feedback coefficient obtained on the basis of the output of the O2 sensor 4. In this case, when the exhaust gas temperature detected by an exhaust gas temperature sensor 3 is the lower, the feedback coefficient is made the smaller, and thus a fuel supply means 8 is controlled so that the fuel injection quantity becomes the value corrected by this coefficient.
