Title: Slip control device for vehicle
Inventor: YAMASHITA TETSUHIRO
IPC: F02D45/00
Filed: 1990-11-29
Abstract: PURPOSE:To prevent slip control from starting unnecessarily by compensating an apparent slip length, based on a compensating constant which is set so that a compensating amount may become larger as a bad road level is higher. CONSTITUTION:In a control means 8, based on a bad road level discriminated by a bed road level discrimination means 24, an apparent slip length detected by an apparent slip length calculating means 11 is compensated, based on a compensating constant which is set so that a compensating amount may become larger as the bad road level is higher. By this, even if the speed of driving wheels 2FL, 2FR becomes high instantaneously, slip control is prevented from starting by it. This compensation is not uniform, however, the compensating amount is changed according to a bad road level, so it is possible to obtain basic increasing or decreasing tendency of slip length regardless of the bad road level, and to ensure slip control response without any interference.

Title: Method for evaluating thin steel-plate product
Inventor: ISONO TAKAHIRO
IPC: G01N33/20
Filed: 1996-12-16
Abstract: PROBLEM TO BE SOLVED: To make the shipping schedule changeable to a schedule for a usage, where no quality problem is generated due to an inclusion, by estimating the maximum particle diameter of the inclusion from the inclusion particle diameter measurement result of a small amount of sample, and predicting a product defect detection frequency based on the correspondence relationship between the maximum particle diameter of the inclusion and the product quality that are made clear for every steel kind in advance. SOLUTION: Strictly speaking, all inclusions exceeding a critical particle diameter are required to be evaluated to predict a defect caused by the inclusions. However, by using a mutual relation, information corresponding to the number of inclusions with a large particle diameter can be obtained by determining the particle diameter of the maximum inclusions instead of evaluating the number of inclusions with a large diameter, thus predicting the occurrence frequency of defect. The maximum particle diameter of the inclusions observed in a plurality of samples sampled from a steel material is measured, and the maximum particle diameter of the inclusions contained in the steel material of a base material is estimated from the extreme value statistics.  The corresponding relationship between the maximum particle diameter of the inclusions and the quality defect differs depending on the applications of the steel, for example, between a material that is used as a flat plate without being machines nearly at all and a steel material subjected to strong machining.

Filed: 1988-12-29
Abstract: PURPOSE:To improve the working efficiency by interrupting an executing working program on demand to permit the manual operation and immediately continuing the working program from interruption coordinates at the time of restarting the working program after the completion of this manual operation. CONSTITUTION:When an interrupt switch 25a is turned on while the working program is executed, a CPU part 21 interrupts execution of the working program and executes an interrupt program preliminarily stored in a storage part 22 and stores coordinates Pn of a working process Kn, where the working program is interrupted, in the storage part 22. When the working program is restarted, a table and a working head are moved to stored coordinates Pn, and the working program is restarted from this position. Thus, idle working is eliminated when the working program is restarted after being interrupted, and the working time is shortened to improve the working efficiency.

Abstract: PURPOSE: To surely confirm before starting supplying propellant the possibility of propellent leakage at the time of supplying the propellant from a supplying craft to a spacecraft by providing a test gas detector for detecting the existance of the test gas inside a bellows at the time of connection. CONSTITUTION: When there is a poor connection between a propellant receiving unit 2 and a propelleant delivery unit 32, He gas leaks from a connection 29 but the leaked He gas is not dispersed in the space but floats within a space 47 completely enveloped airtightly by bellows 18, 40, specially near the connection 29 connecting a propellant injection tube 6 to a propellant supply tube 35. For this reason, the leaked He gas is collected by a detector line 22 and sent to a test gas detector 26 carried on the spaceraft 1 where its existance is detected. Thus He gas mixing in the atmosphere near the connection 29 of the propellant receiving unit 2 to the propellant delivery unit 32, or in other words, poor connection of the connection 29 and propellant leakage at the time of supplying caused by the poor connection is immediately confirmed.
