Title: Semiconductor integrated circuit
Inventor: KANBARA SHIRO
IPC: H01L21/8234
Filed: 1995-03-06
Abstract: PURPOSE: To completely fix a substrate potential and to completely suppress the creeping of minority carriers into partial circuits constituting an integrated circuit by a method wherein a carrier recombination layer formed by a gold diffusion or a charge irradiation is formed in the prescribed boundary between the partial circuits constituting the circuit. CONSTITUTION: Bonding pads 8 and a lead frame 3 are connected by using respective bonding wires 4 so that an integrated circuit constituted on a silicon substrate 2 arranged on a ceramic package 101 can be connected to external pins. In addition, in order to fix a substrate potential, the lead frame is brought into direct contact with the substrate by using a lead frame 5 for the rear of the substrate. A carrier recombination layer 1 is formed in the boundary between desired poartial circuits constituting the integrated circuit. The recombination layer 1 functions so as to prevent a minority carrier noise from creeping into the desired partial circuits. The recombination layer 1 is formed while an electron beam or protons are irradiated or gold is diffused.

Title: Shift control device for vehicular automatic transmission
Inventor: TABATA ATSUSHI
IPC: F16H61/06
Filed: 1995-03-06
Abstract: PURPOSE: To prevent the occurrence of an erroneous learning correction control process by stopping a control process on the operation of an overshoot learning control means, upon judging that an engine overspeed prevention control process is under way during a clutch-to-clutch gear change. CONSTITUTION: An engine overspeed prevention means 158 cuts out a fuel from a fuel injection valve 80 on the operation of an engine electronic control device 76 and a gear change electronic control device 78, when an engine speed exceeds an overspeed judgement reference value during a clutch-to-clutch up-shift gear change during a travel under a high load.

An overspeed prevention control and execution judgement means 168 makes judgement as to whether a control process with an engine overspeed prevention means 158 is under way during the gear change.  If affirmative, a control stopping means 170 interrupts the control process with the means 164. As a result, erroneous learning can be prevented.

Title: Semiconductor logical circuit
Inventor: NOKUBO JIYOUJI
IPC: H03K19/086
Filed: 1983-03-18
Abstract: PURPOSE:To avoid oscillating phenomenon even if a high performance transistor (TR) is used by connecting one end of a load resistor of a differential amplifier to a base of an output TR and connecting the other end to a collector of the said output TR. CONSTITUTION:Load resistors R1, R2 of differential amplifiers Q3, Q4 are connected to a VCCA terminal, i.e., a collector of an output TRQ1. Since a parasitic impedance Z existing between the base and collector of the output TRQ1 is connected in parallel with R1 and the relation of ¦Z¦<R exists, the impedance between the base and collector of the Q1 depends on nearly a pure resistor, R1. Since the feedback from the collector to the base is in-phase in terms of phase, an output of the collector is shifted by 90 deg. by the operation of an L2 to a minute input voltage to the base due to initial noise, and the phase is not shifted further by >90 deg. nor fed back to the base, then no oscillation is produced.
