摘要： PROBLEM TO BE SOLVED: To control a permanent magnet field synchronous motor, operated by a multiphase AC power generating means with a voltage command vector as an input by applying phase voltage in accordance with this voltage command vector, with good accuracy even in a small range of the voltage command vector. SOLUTION: A permanent magnet field synchronous motor current is detected at every control period, a position angle and an angular speed of a rotor are calculated, based on this calculation and a torque command, a voltage command vector is determined. When a level of the voltage command vector is decreased smaller than a prescribed lower limit value, at a correction period formed by a control period of prescribed number thereafter, a pulse voltage vector is added at every control period to the voltage command vector (Vd, Vq) so as to make an average be 0 in the correction period, this vector is inputted as the voltage command vector after correction made to the AC power generating means.

摘要： PURPOSE:To securely detect a precedent vehicle and to prevent a distance display from being interrupted by comparing the absolute values of the speed and acceleration of a body at the front which are calculated from the distance to the body at the front and the speed of the vehicle on this side with absolute values. CONSTITUTION:The distance (r) to the body at the front which is measured by a distance meter 1 and the speed (u) of the vehicle on this side which is measured by a vehicle speed sensor 2 are inputted to a computer 3. Then when the absolute value of the acceleration of the body at the front exceeds the specific value or when the speed of the body at the front is less than the specific value, it is decided that the body at the front is the precedent vehicle and the distance display 4 is started. If a distance measuring beam deviates from the precedent vehicle in this state owing to the pitching vibration of the vehicle on this side, the absolute value of the acceleration exceeds the specific value. In this case, a distance which is predicted from a distance which is a certain period before and the relative speed with the body at the front is outputted until the precedent vehicle is caught within a specific time and the difference between the detected distance and predicted distance decreases below a constant error, thereby evading the interruption of the display 4.

摘要： PURPOSE:To narrow the dead angle area at which no laser light will hit an obstacle by additionally emanating a laser light with a large angle of emanation thereto enough to overlap the emission area of a laser with a specified angle of emanation. CONSTITUTION:An obstacle is irradiated with a laser light from long-range optical systems 200 and 300 with a specified angle of emanation. In addition, it is irradiated with a laser light with a large angle of emanation enough to overlap the emission area of the laser light from a short-range optical system 400. With such an arrangement, laser light is irradiated on a short-range obstacle to narrow the dead angle area at which no laser light will hit the obstacle.

摘要： PURPOSE:To accurately detect the distance of an obstacle and to attain to enlarge the titled apparatus while avoiding the rising in cost without widening the dynamic range of a receiving circuit, by controlling the gain of the variable gain amplifier provided to a transmission circuit or a receiving circuit so that the output of the receiving circuit is not saturated while stopping distance operation when the output of the receiving circuit is saturated. CONSTITUTION:Because distance data K1 is outputted from a counter 83a, the output from the terminal E of a comparator 84 comes to an ''1'' level. When a timing pulse signal (a) is inputted to an AND gate 89b, a gate 89b is opened and a clock pulse signal (g) is inputted to an AND gate 89c and a counter 83b. Unless the output signal (h) of an amplifier circuit is saturated, a signal (n) comes to an ''1'' level and a gate 89c is opened to input the clock pulse signal (g) to a counter 85 as a signal (p). The signal (p) is continued before the gate 89b is closed when count data K2 becomes equal to the distance data K1. By this method, the distance data K1 is integrated in the counter 85.

摘要： PROBLEM TO BE SOLVED: To suppress a peak value of a recovery surge voltage from becoming large. SOLUTION: A power supply device includes: a battery 29; a film capacitor 21; transistors 23, 25; gate resistors 24, 26; a flywheel diode 22; a current sensor 27; and a control unit 30. When a load current detected by the current sensor 27 is equal to or lower than a prescribed value, the control unit 30 outputs an on-signal to one of transistors 23, 25 (for example, only the transistor 23), and when the load current is larger than the prescribed value, the control unit outputs on-signals to both the transistors 23, 25. By this arrangement, the peak value of the recovery surge voltage can be suppressed from becoming large without using a large gate resistor, and a loss caused by the gate resistor can be suppressed.

摘要： PROBLEM TO BE SOLVED: To provide an on-vehicle antenna for communications between road and vehicle in which communications between a road and a vehicle can be performed without being interrupted even when a communication disable area exists in the boundary of mutually adjacent blocks. SOLUTION: An on-vehicle antenna 12 is composed of a pair of loop antennas (coils) 12a and 12b having the same form (cylindrical form), the same size and the same number of winding wires while being serially connected to generate the magnetic fields of the same strength and the same direction when currents flow and a tuning capacitor 12c constituting a resonance circuit together with a pair of loop antennas 12a and 12b. When the radius of a loop part is defined as (d) and a distance between the antenna terminals of road side antennas is defined as (y), the loop antennas 12a and 12b are fixed on the lower surface of a vehicle M with the location so that an interval (x) between the central points of both the loop antennas 12a and 12b can satisfy the condition of y
