Title: Optical magnetic field measurement apparatus
Inventor: SAWA TAKESHI
IPC: G01R33/032
Filed: 1990-09-20
Abstract: PURPOSE:To provide an optical magnetic field measurement apparatus with high measurement precision even when an environmental temperature changes by subtracting a DC voltage proportional to the temperature of a light source from a DC component of an output voltage of a photo-detector when an AC component of the output voltage of the photo-detector is divided electrically by the DC component. CONSTITUTION:An optical magnetic field measurement apparatus for measuring alternative current magnetic field consists of a light source 1, a magneto-optic material 5 a photo-detector 9, and a signal processor 10, in which the Faraday effect is used and the measurement is carried out through dividing electrically an AC component of an output voltage of the photo-detector by a DC component. The characteristics are presented as a DC voltage proportional to the temperature of the light source 1 is subtracted from the DC component of the photo-detector output voltage. When temperature of the light source 1 changes, the emitted peak wavelength changes and the AC component of the photo-detector output voltage changes, however, by using this optical magnetic field measurement apparatus, the DC component of the output voltage of the photo-detector 9 changes in the same way as that of the AC component according to the DC voltage proportional to the temperature variation of the light source 1 therefore, the output after dividing operation by the signal processor 10 can be maintained constant.

IPC: B62D57/024
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To safely and efficiently transport a maximum loadage by moving a loading part so that a composed gravity center position falls within a proper range by considering the total weight of the loading part including a live load or the live load. SOLUTION: In a moment when the rear end of a rear crawler mechanism separates from a single step of stairs, a contact point with the crawler mechanism in a step above by a single pitch is denoted by Y. An intersection between a perpendicular A from the contact point Y and a bottom surface of a loading part 5 is denoted by (a). A perpendicular B perpendicular to a traveling device by passing through this intersection (a) becomes the lower limit of a gravity center proper range of the traveling device of the composed center G of gravity. In a condition where the composed center G of gravity comes to the lower side of the stairs than the perpendicular A, the possibility of overturning to the lower side of the stairs is produced. Then, in order to prevent overturning, a loading part 5 is slidingly moved the upper side of the stairs according to a calculated moving distance.  As a result, the center G2 of the gravity of a live load moves in the upward direction of the stairs, and as a result, the composed center G of gravity also moves in the upward direction of the stairs, and can be made to fall within a proper range.

RB and RC take the same resistance value and the intermediate value of measured value voltage VA and reference voltage VM is taken out to the connection point of both resistors as VB. A control part 1 outputs a graded digital value rising or falling by minute voltage DELTAV at every predetermined minute time DELTAt and, when the output logic of an OP amplifier IC3 is reversed, for example, returns the digital value to the output value one step before and again outputs the rising or falling digital value. The control part 1 outputs the reversed output value or the output value one step before as a measured data.
