Title: Learning control of air-fuel ratio of internal-combustion engine
Inventor: SUEMATSU TOSHIO
IPC: F02D45/00
Filed: 1982-06-29
Abstract: PURPOSE:To prevent learing memorization with erroneous value by prohibiting learning memorization of the corrected value of an air-fuel ratio when the temperature of an O2 sensor increases, in said learning memorization of the corrected value which is corrected according to the difference between the real air-fuel ratio and the aimed air-fuel ratio, when the air-fuel ratio feedback conditions are satisfied. CONSTITUTION:In the captioned control, the basic injection amount which is obtained from each output of an air flow meter 12 and a revolution angle sensor 32 is corrected according to the output of a cooling water temperature sensor 34, in a digital control circuit 38. When the air-fuel ratio feedback conditions are satisfied, the air-fuel ratio is feedback-controlled according to the difference between the air-fuel ratio obtained from the output of an O2 sensor 26 and the aimed air-fuel ratio, and the corrected value of air-fuel ratio is learning-memorized. Said corrected memory value is used when the air- fuel ratio is feedback-controlled when the feedback conditions are not satisfied. With such a constitution, when the temperature rise of the O2 sensor 26 is foreseen, the feedback control of air-fuel ratio and learning memorization of the corrected value of air- fuel ratio are prohibited.

Title: Rolling sliding component
Inventor: NOGUCHI SHOJI
IPC: F16H53/06
Filed: 1992-04-06
Abstract: PURPOSE:To cause a rolling sliding component to exhibit excellent abrasion resistance for both sliding friction and rolling friction so as to enhance durability of various machine equipment by increasing the maximum compression residual stress of the surface layer portion of the rolling sliding component, and heightening the hardness of the surface layer portion while increasing the average value of the radius of curvature of each micro protrusion. CONSTITUTION:This rolling sliding component is used in rolling or sliding contact with another opposite component. Particularly when the surface layer portion of the component has a depth of 0 to 50mum from the surface the surface layer portion has a maximum compression residual stress of 90kgf/mm<2> or more and a hardness of HV 780 or more. The radius of curvature of the end of each micro protrusion present on the surface has an average value of 90mum or more. Stress applied to the end portion of each micro protrusion is thereby reduced to a small amount and abrasion of the end portion can be reduced to a small amount.

IPC: G06Q20/42
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To realize high security without imposing load to a user and a system in a user authentication device to be used for used authentication. SOLUTION: The user authentication device 1 is provided with a calculation means 14 for calculating a numerical value to be used for user authentication from random numbers presented to a user and a calculation expression corresponding to a user authentication object and a judgment means 15 for judging whether a numerical value inputted in response to the indication of the random numbers coincides with the numerical value calculated by the calculation means 14 or not. When the calculation expression is a numerical string not including an operator, the calculation means 14 outputs the numerical string as a calculated result. Even when a numerical value inputted by the user is looked at by another person, the secrecy of the numerical value can be held in the constitution and high security can be realized.  Since it is sufficient for the user to memorize only the calculation expression and for the system to store only the calculation expression, high security can be realized without imposing load to the user and the system.

Title: Spin coater
Inventor: YAMADA MAMORU
IPC: H01L21/027
Filed: 1988-05-09
Abstract: PURPOSE:To change the direction and position of discharge during the overshoot of the discharge pressure of an organic solvent, and to prevent attachment onto the surface of a semiconductor substrate of the organic solvent by moving a discharge nozzle for the organic solvent for washing the rear. CONSTITUTION:A photo-resist is applied to a semiconductor substrate 1, and a nozzle 3a discharges an organic solvent as a locus 4a. Even when the discharge pressure of the organic solvent overshoots immediately after the start of discharge, the organic solvent is discharged during overshoot at a position near a shaft because the organic solvent does not fly up to a coater cup wall surface 5. When the period of overshoot is completed, the nozzle 3a is moved up to a position 3b, discharges the organic solvent and removes the photo-resist adhering on the rear of the substrate 1. Accordingly, bonding with the surface of the substrate 1 of the organic solvent is prevented.
