摘要： An object is to provide in a positioning device of a moving body such as a vehicle, a technique which can modify a built-in clock error of a moving body to increase accuracy of a velocity. The positioning device includes a built-in clock error estimating unit which estimates a built-in clock error of the vehicle as a built-in clock error based on a difference between a delta range and a calculated range rate, and a range rate estimating unit which estimates a vehicle stop range rate based on position and velocity of GPS satellite based on transmission signal and a vehicle position, and modifies a calculated range rate, based on the built-in clock error. Further, the positioning device includes an own vehicle velocity calculating unit which calculates own vehicle velocities in three axial directions which form an orthogonal coordinate system, based on a navigation matrix, the vehicle stop range rate and the modified calculated range rate.

摘要： A vehicle position display controller performs a branch determination processing of determining whether a vehicle has entered a branch road. In addition, in a case where a connecting road through which a currently traveled road is connected to a road extending in parallel with the currently traveled road lies ahead of a position of the vehicle, the vehicle position display controller performs a road shape conversion processing of subjecting the road extending in parallel to the branch determination processing on the assumption that the road extending in parallel is the branch road by making a correction of an angle between the currently traveled road and the connecting road. However, in a case where the vehicle travels at a speed equal to or greater than a predetermined speed, the vehicle position display controller does not perform the road shape conversion processing.

摘要： In a method of corona discharge processing of resin formings surface, excellent corona discharge processing is possible, even if there is a distance between the resin formings and the discharge electrode, by generating a high voltage pulse having a pulse width of 1 .mu.s or more, an average electric field strength of 4 to 20 kv/cm denoted by applied voltage (wave height) versus interelectrode distance, and a pulse frequency of 10 pps or more. This processing is performed by the apparatus which comprises arranging a transfer conveyor to transfer the resin formings, a counter-electrode placed in a down side of the transfer conveyor, a dielectric to cover a surface of the counter-electrode, and a number of discharge electrodes which are arranged in a definite distance above the resin formings along the transfer route.
