Title: Vehicle traveling control method for carrier
Inventor: NISHII HISAO
IPC: G05D1/02
Filed: 1992-12-02
Abstract: PURPOSE:To eliminate the influence of gravity on a sloping surface and also to reduce the error of a traveling lows in regard of a vehicle traveling control method by calculating the reaction affecting the right and left wheel motors by the gravity from the stress affecting both motors and then by applying the feedforward control to these motors in order to eliminate the influence of the reaction. CONSTITUTION:The reaction fmR to a right wheel motor MR due to influence of the gravity is given to a resistance/torque element 71a, and the reaction fmL to a left wheel motor ML is given to a resistance/torque element 71b, respectively. Then, each motor voltage is given to the subtraction elements 63a and 63b, respectively. Thus, the armature voltage of both motors ML and MR obtained by the amplification elements 62a and 62b are added to the motor voltage obtained by both elements 71a and 71b. At the same time, the counter electromotive voltage proportional to the rotational angle velocity fed back from the counter electromotive voltage constant elements 69a and 69b are subtracted from the result of the preceding voltage addition. The result of this subtraction is given to the resistance/torque elements 64a and 64b.

Abstract: PROBLEM TO BE SOLVED: To prevent the loss of light quantity from occurring, when color resolution and color combining are executed by separating a light beam into two light beams having angular difference, rotating the plane of the polarization of only the light beam in a specified wavelength area, while maintaining the angle difference and converging the light beams. SOLUTION: Light beams RP, GP, BP, RS, GS and BS emitted from a light source 11 are separated into the P-polarized light beams RP, GP and BP and the S-polarized light beams RS, GS and BS by giving the angular difference by polarized light separation device 12 and are made incident on a specified wavelength region polarized light conversion device 13. Since the plane of the polarization of only the G light beam in the specified wavelength region is rotated by 90 deg. by the conversion device 13, the G light beam GP which was the P-polarized light beam is converted into the G light beam GP which zwas the P-polarized light beam and the G light beam GS which was the S-polarized light beam is converted to the G light beam GP which was the P-polarized light beam.  Therefore, two sets of light beams RP, GS and BP and light beams RS, GP and BS are emitted from the conversion device 13 and made incident on a converging optical system 14. Moreover, a 1/2 wavelength plate 15 is arranged near the converging part of the light beams RP, GS and BP and the plane of the polarization of the transmitted light beam is rotated by 90 deg.. Thus, the R light RP which was the Ppolarized light beam, the G light beams GS which was the S-polarized light beam and the B light beam BP the P-polarized light beam are converted to the R light beam RS being the S-polarized light beam, the G light beam GP being the P-polarized light beam and the B light beam BS being the S-polarized light beam.

Title: Method and system for monitoring of collapse of slope
Inventor: CHICHIBU AKIYOSHI
IPC: G08B21/00
Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To obtain a method and a system in which the collapse of a slope as cut, filling or the like is judged with high accuracy without any malfunction. SOLUTION: An AE waveform which is detected by an AE sensor which is installed at a slope or the like is input to an AE parameter part 5 via an AE amplifier 4. The AE parameter part 5 computes the AE waveform so as to obtain a continuity degree parameter. The continuity degree parameter expresses a continuity degree in such a way that the input AE waveform is envelope-detected and that the time which exceeds a threshold value within a unit time is measured. A data analytical part 6 judges whether the continuity degree parameter which is continued for a prescribed time in the prescribed number of seconds contains the prescribed numbers of times or higher.  When the number of continuity degrees in the continuity degree parameter is at a judgment reference or higher, the generation of the collapse of the slope is detected, and an emergency signal is output to a warning device together with slope position information which is set in an input data part 7.
