IPC: G01R31/01
Filed: 2000-07-05
Abstract: PROBLEM TO BE SOLVED: To reduce unit test time and improve production efficiency by determining a measurement date in a learning phase beforehand to an application phase by means of a criterion applied to a population of accepted components and adjusting the measurement date determined in the course of an adjustment phase during an application phase. SOLUTION: In a first learning phase, an electronic component is tested at a measurement date which is equal to a nominal measurement date, and after the test, an allowable component and a rejected component are discriminated on a wafer and an earliest possible date is chosen between a minimum threshold value and a nominal value. In the course of the adjustment phase during an application phase, an earliest possible measurement date chosen at the time of a learning phase is considered val, an adjustment phase is much faster than a learning phase, and a measurement date which is proper for characteristics of a batch to be tested can be chosen. As a result, it is possible to define a new measurement time for another time each for each new manufacturing batch and each wafer, thus cutting a unit time test and improving production efficiency.

IPC: B60W10/06
Filed: 2000-07-10
Abstract: PROBLEM TO BE SOLVED: To prevent braking distance from becoming long against the driver's will, during braking in a state that slipping of drive wheels involved in braking cannot be detected. SOLUTION: Drive wheels 12 are braked by the regenerative braking of a drive motor 26, based on the switchback operation on an acceleration lever 22, and further slipping velocity ΔVD for detecting slipping of the drive wheels 12 is determined from the number of front wheel revolutions NLF (NRF) and the number of rear wheel revolutions ND1 (ND2).
