摘要： A vehicle door lock system has a lock mechanism for locking or unlocking the vehicle door. A control mechanism for controlling an operation of the lock mechanism includes first and second resonators. The first resonator resonates at a predetermined first value Q for transmitting a first signal to the outside of the vehicle. The second resonator is connected in series with the first resonator and resonates at a second value Q which is greater than the first value Q, and changing a resonant condition in accordance with a change of a capacitance. A single actuator is provided for actuating the first and second resonators. A switching mechanism is provided which utilizes the actuator for alternatively switching actuation between the first and the second resonators. The control mechanism controls the switching operation of the switching mechanism and the operation of the door lock mechanism in accordance with the resonant condition of the second resonator.

摘要： A microstrip antenna device for circularly polarized waves includes a dielectric sheet member, one surface of which has a radiating conductor sheet member while the opposite surface has a ground conductor sheet member. Denoting a point where a segment of a line passing through a geometrical center o, o of the radiating conductor sheet member intersects with the substantial periphery of the radiating conductor sheet member by a and denoting a point where the segment intersects with the substantial periphery of the ground conductor sheet member by b, the ratio of the length between the points o and b to the length between the points o and a should be at least equal to 1.5. Where rectangular radiating and ground conductor sheet members are used, a good circular polarization is achieved without any disturbance in the radiating pattern when the diagonal ratio of the respective members is equal to or greater than 1.5.
