Title: Vehicle body inclination angle controller for rolling stock
Inventor: SATO KUNIHITO
IPC: B61F5/10
Filed: 1998-01-09
Abstract: PROBLEM TO BE SOLVED: To keep a vehicle body almost at a central position in the lateral direction for preventing occurrence of impulsive force by a contact of the vehicle body with a stopper by generating the force kept almost at a central position in the lateral direction against the displacement force of the vehicle body in the lateral direction to a truck while it is running through the curved sections of tracks. SOLUTION: While a railway vehicle is running on tracks 26, centrifugal force and centripetal force are almost cancelled by each other at the upper surface part of a diaphragm type air spring 24. At the lower surface part 35 of the diaphragm type air spring 24, the air spring 24 receives only centripetal force by cant angle ϕ0, therefore, centrifugal force is not cancelled. The air spring 24 has flexibility in the lateral direction, therefore the diaphragm type air spring 24 is deflected to the outside in the turning direction because of centrifugal force of no cancellation, so that the vehicle body 14 deflects to the outside in the turning direction. By the centripetal force canceling the centrifugal force of no cancellation is applied to the vehicle body 14, the vehicle body 14 is maintained at the central position in the lateral direction even while turning.

The respective analyzed brain wave signals are inputted to a band pass filter 6 and only an alpha-wave component is extracted. For this alpha-wave, for example, the average of the alpha-wave appearance ratio from the past to present in the worker is obtained by using a 1st time coverage value calculation I7 and defined as the average alpha wave appearance rate of the worker. When a ratio R of the alphawave appearance rate is almost equal with '1', and the alpha-wave appearance rate at the time of working is considered almost equal with the average alpha-wave appearance rate of the worker and it is decided that work execution ability is not especially lowered. When the R is lowered less than '1', it is decided that the worker is in an instable period.

Abstract: PURPOSE:To eliminate the need for a high-accuracy resistance and to reduce higher harmonic distortion by providing a circuit which shapes output pulses which vary in the sum of pulse width in a period of (n) clock pulses according to the contents of digital data and also vary in pulse width and pulse period. CONSTITUTION:A pulse generating circuit 6 which inputs digital data from a data input part 1 and the output of an (n)-scale counting circuit 5 varies the sum of pulse width in an (n)-clock period as one conversion period according to the contents of digital data and also varies the pulse width and pulse period. Further, a selective synthesizing means 7 selects and adds either of the 1st and the 2nd potentials according to the output pulse of the pulse generating circuit 6 and outputs an analog signal so that the 1st and the 2nd potentials are dispersed widely in one conversion period according to the digital data. Consequently, the higher harmonic spectrum of the analog signal output is large in a high frequency range and small in a low frequency range. The output of a D/A converter is band-limited to <=1/2 as large as a conversion frequency, so this invented converter having a small higher harmonic spectrum in a low frequency range reduce higher harmonic distortion.
