Title: Air-fuel ratio controller for internal combustion engine
Inventor: MIYASHITA KOTARO
IPC: F02D41/04
Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To provide a controller which changes air-fuel ratio smoothly to targeted lean air-fuel ratio in starting the lean feedback control of the air-fuel ratio, minimizes NOx exhaust amount, and conducts feedback control at a point where the drivability and fuel consumption harmonize with each other. SOLUTION: It is discriminated whether or not the absolute value |DKCMD| of a deviation between the present value KCMD (n) of a targeted air-fuel ratio coefficient KCMD calculated from KBS value and a previous value KCMD (n-1) is larger than a combustion variation determination prohibiting threshold value DKCMDX2 (S1507, S1509), and if it is larger, a combustion unstableness monitoring determination flag FSLBFB is set at zero, so correcting the targeted air-fuel ratio coefficient KCMD value to a rich side, which is caused by unstable combustion, is not conducted. Therefore, the targeted air-fuel ratio is prohibited from being corrected erroneously to the rich side by erroneously-judging a torque variation generated when a targeted air-fuel ratio is changed from theoretical air-fuel ratio to targeted lean air-fuel ratio to be unstable combustion.  It is thus possible to change the targeted air-fuel ratio to the targeted lean air-fuel ratio smoothly.

Title: Tape tension mechanism
Inventor: UCHIYAMA SADAO
IPC: G11B15/43
Filed: 1989-08-31
Abstract: PURPOSE:To quickly perform migration from a stopping state or a fast feeding state to a playing state by providing two tape contact parts at a tape contact member. CONSTITUTION:Two tension adjusting pins 14, 14 are provided at the tape contact member 25. If a tension adjusting pin 14' with a prescribed energizing force comes in contact with a magnetic tape 4, an angle theta is formed. Since the pins 14 are located at a position in the neighborhood of a guide post 6 or a tape loading post 8 at the member 25 compared with one pin 14', it is enough to rush them to the tape 4 lightly to impart the same tension. Therefore, a gap B between a tape contact position and a tape separating position is reduced by width where rushing quantity is reduced. In such a way, the migration from the stopping state or the fast feeding state to the playing state is quickly performed in a short time.

Filed: 1990-08-30
Abstract: PURPOSE:To effectively prevent disturbance of performance of heat resistance, solder wettability, die bondability of a gold plated layer by heat treating by employing platinum or platinum alloy plating as gold base plating. CONSTITUTION:Platinum or platinum alloy plating is employed as a base of gold plating. That is, platinum and platinum alloy are scarcely oxidized as the base of gold plating, and have excellent characteristics as metal diffusion barrier and characteristic for scarcely generating gold and metal compounds. Accordingly, platinum or platinum alloy plated layer is interposed as a barrier between the metal and the gold plating layer of an electronic component package. Thus, even if the package is heat treated, the metal part is not present on the surface of the gold plating, and gold plating is not discolored. Thus, performance such as die bondability, cap sealing, solder wettability of the gold plated layer is prevented from deteriorating.
