IPC: F16H1/28
Filed: 1988-11-18
Abstract: PURPOSE:To reduce vibration by constituting a device to be composed of the speed reduction section of a spur gear speed reduction mechanism which consists of a planetary gear meshed with a sun gear fixed on an input shaft, and of the speed reduction section of a speed reduction mechanism depending on the difference in a small number of teeth which is meshed with an external teeth gear pivotally mounted on a crank section and with an internal teeth gear pivotally mounted on an output side member. CONSTITUTION:Three planetary gears 3 are arranged at 120 deg. intervals around a sun gear 2 fixed on an input shaft 1, and each planetary gear pivotally mounts a crank shaft 4 composed of two crank sections, and each crank section pivotally mounts external teeth gears 6 and 7 rotatably via a bearing 5. Each of two crank sections in the crank shaft 4 in the eccentric direction is dislocated by 180 deg. in phase, and the phases among three each of the crank shafts in the eccentric direction are synchronized. The gears 6 and 7 are therefore dislocated by 180 deg. in phase. Internal teeth gears 9 and 10 are coaxially arranged around a gear 2 wherein the gear 9 pivotally mounted by a stationary side member is meshed with the gear 6, and the gear 10 pivotally mounted by an outside member is engaged with the gear 7. This constitution permits speed reduction to be performed in two steps.

Then, after electric charges are discharged, the layer 9 is thrown to Z' side, thus enabling a capacity C and tan delta to be measured. Then, a carrier resistance R is obtained by R=1/(omegaCtan delta). An angular frequency omega is determined by a measurement frequency f, namely omega=2pif. Also, the resistance R is expressed as R=(g/s).rho by using a resistivity rho. s indicates a sectional area of the electrode, thus obtaining rho=(s/g).R=(s/ g).(1/omegaCtan delta). A relationship among the gap, resistance, and resistivity can be obtained from the above expression.

Title: Position detector
Inventor: SHIMIZU OSAMU
IPC: G01C21/00
Filed: 1993-11-24
Abstract: PURPOSE:To improve the detection accuracy of a global positioning system (GPS) without deteriorating the advantage of the GPS by removing the amount of an error from GPS signals during a fixed period of time after finding the error contained in the GPS signals. CONSTITUTION:A position detecting and processing section 2 detects the accurate position of a vehicle based on the positional data of map matching or a beacon receiver 6 or the picture information of a picture recognizing and processing section 7. Then the section 2 compares the position detected by means of a GPS receiver 1 only with the accurate position and finds the error contained in the detected results of the receiver 1 only. The error contained in the signal of a GPS satellite 3 thus found hardly changes during a fixed period of time (about 10-20 minutes). Therefore, the section 2 stores the error and corrects the position of the vehicle detected by the receiver 1 only by subtracting the error from the detected results of the receiver 1 only during a fixed period of time. The position detecting error is updated whenever the accurate position of the vehicle is detected.
