Title: Driving force controller for vehicle
Inventor: TAMURA MINORU
IPC: B60T8/175
Filed: 1990-02-14
Abstract: PURPOSE:To decrease cornering force and prevent generation of spin by forbidding control of decrease in driving force in the case sideslip of driven wheel is detected, or varying a threshold value of detection of driving slip used for the control. CONSTITUTION:Output pulse signals of wheel rotation sensors 4-7 provided at every wheel are inputted to a CPU 11 via a F/V converter 9 an A/D converter 10 of a driving force control part 8, and existence of generation of driving slip of driving wheels is judged based on every rotation number of the wheel. At the judging time of the driving slip, a fuel cut signal is transmitted to a fuel supply control unit 12, and the fuel cut with respect to cylinders 13-1 - 13-6 is excessed so as to suppress the driving slip. It is judged whether sideslip of the driving wheel is generated or not based on a comparison result of respective threshold values of deceleration speed of the driving and driven wheels. When it is judged YES, the fuel cut control is forbidden.

Title: Electric contact and its manufacture
Inventor: UCHIDA MASAKI
IPC: H01R43/16
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To provide such an electric contact that corrosion resistance is improved or the cost is decreased in the case that corrosion resistance is sufficient even if it is equal to the former one. SOLUTION: Irregulaities or a non-conductive layer on the surface of a parent metal is removed by polishing a contact surface to thereby make surface roughness of the parent metal smaller, before plating the parent metal such as a copper alloy or the like of the electric contact. The surface roughness is made 0.05 μm-0.7 μm by polishing. Hereby, under the same gold plating conditions, corrosion resistance can be improved remarkably by decreasing the number of pinholes remarkably, and even in the case of thin gold plating, corrosion resistance equal to that of a comparatively thick former plating can be obtained.
