Title: Vehicle-position detecting system
Inventor: SUGIURA TADASHI
IPC: G01C21/00
Filed: 1985-07-27
Abstract: PURPOSE:To make the entire system simple and accurate and to eliminate accumulation of errors, by detecting the magnetic intensities of magnets, which are embedded in the front wheels of a vehicle, by a plurality of detecting elements. CONSTITUTION:When front wheels are rotated, magnets, which are embedded in the front wheels, are approached to or separated from magnetism detecting elements 1-5 and 11-15. Thus the magnitudes of the electric outputs of the elements 1-5 and 11-15 are changed. The maximum value of the electric output is changed by the angle of each front wheel. Then, the outputs of the elements 15-5 and 11-15 are amplified by an amplifier part 41 and converted into digital values in an A/D converter part 41. The values are inputted to an operating part CPU 43. Starting data at the time of starting is imparted to the CPU from an input part 46. The outputs of the elements 1-5 and 11-15 give the slant angles of the wheels in the right and left directions. The slant angles and the numbers of rotations of the front wheels are computed in the CPU and outputted. In a memory part 47, map data including the running range of the vehicle are stored. The map data are inputted in the CPU. After processing, the data are displayed on a display part 45 through a display driving part 44.

IPC: G01N3/32
Filed: 1981-10-19
Abstract: PURPOSE:To perform a high-precise measurement of an internal friction, by a method wherein a phase difference between a torgue and a twisting displacement is detected as a time delay between a current, flowing to a Helmholtz coil, and a detecting signal, corresponding to a twisting displacement of twist pendulum photoelectrically detected. CONSTITUTION:A measuring device for internal friction is provided with a sample 10, a concave mirror 14, a Helmholtz coil 22, amplifiers 24, 32 and a light volume difference meter 30.

Title: Apparatus for measuring amount of oil application
Inventor: TANAKA TAKEO
IPC: G01N31/12
Filed: 1983-09-12
Abstract: PURPOSE:To measure the amount of the application of oil on a sample highly accurately, by burning the oil on the sample by heating, generating CO2 gas, operating the output signal from an infrared-ray gas analyzer, and multiplying the result by a coefficient corresponding to the kind of the oil. CONSTITUTION:When a sample 2 is put in a sample containing part 1, oil that is applied on the sample is burned with air as a supporting burning gas, and CO2 gas is generated. The CO2 concentration in mixed gas of the CO2 gas and air, which is guided to an analyzer 9, is increased. When the burning of the oil is completed, the CO2 concentration in the mixed gas, which is guided to the analyzer 9, is returned to the CO2 concentration in the air. The amount of the generated CO2 gas depends on the kind and the amount of the applied oil. An operating circuit 11 performs operation with respect to a signal 9a. An output signal 11a of the circuit 11 is increased when the CO2 is started to flow into the analyzer 9. When the flowing of the gas into the analyser 9 is completed, the signal 11a is saturated at a constant value.
