Title: Method for controlling automated guided vehicle
Inventor: CHIN SHIYOMEI
IPC: G05D1/02
Filed: 1995-11-28
Abstract: PROBLEM TO BE SOLVED: To perform steering control by discriminating a linear track and a circular track by operating the curvature radius of guide line from the induced voltage of three pickup coils fixed at the lower part of car body. SOLUTION: A perpendicular coordinate system O-XY is taken at a representative car body point O of an automated guided vehicle, and lateral displacements x1, x2 and x3 are detected by three lateral displacement sensors S1, S2 and S3 at coordinate positions y1, y2 and y3 on the Y axis. The track can be instantaneously expressed circular from these detected values, and a radius γ, lateral displacement quantity δ and azimuth angle deviation θ of car body are calculated by following equations; γ=√((x2-x0)<2> +(y2-y0)<2> ), δ=√(x0<2> +y0<2> )-γ and θ=tan<-1> (y0/x0). When the radius can not be found, it is discriminated that the vehicle travels on the linear track.

IPC: F02M25/07
Filed: 1991-12-18
Abstract: PURPOSE:To reduce generation of smoke and suppress increase of NOx in a wide load region without damaging operation performance in abrupt acceleration or deceleration operation. CONSTITUTION:Various kinds of data are read in to calculate an EGR command value DFIN in compliance with a load state (S10, S20), a change speed term TDD is calculated based on change speed DNE of engine rotation speed in a transient state, further a response time term KTD is calculated based on a present DFIN, and an EGR command correction value TD, being a product of both the TDD and KTD, is added to the EGR command value DFIN (S30-S80).

Abstract: PROBLEM TO BE SOLVED: To provide a station that can receive information including Walsh coding in a plurality of channels and eliminate disturbance from the received information and to provide a method for eliminating the disturbance. SOLUTION: The station is provided with a memory that stores a received signal including a Walsh code in each of a plurality of channels and a signal that is reflected and refracted and with a plurality of 1st signal paths coupled with the memory. Each signal path receives the signal in the memory. The signal passing through the signal path is subjected to a delay and inverse fast Walsh transform and the Walsh code is eliminated from the signal. The phase shift and attenuation in each path can be estimated and the conjugation of the estimation is multiplied with the signal from which the Walsh code is eliminated to produce path outputs of each channel. By combining them, estimation of data from which disturbance is eliminated is obtained.  The disturbance can furthermore be eliminated by providing a plurality of 2nd signal paths corresponding to the 1st signal paths and conducting the above processing.
