Title: Glass antenna system for vehicle
Inventor: WATANABE FUMINORI
IPC: H01Q1/32
Filed: 1996-10-02
Abstract: PROBLEM TO BE SOLVED: To obtain a high reception sensitivity without a preamplifier by placing an antenna conductor and an earth conductor in parallel, connecting electrically a parallel connection circuit of a 1st coil and a capacitor between the antenna conductor and a receiver and causing 1st resonance with a stray capacitance between the 1st coil and a cable. SOLUTION: In the case of receiving a low reception frequency band, an inductance of a 1st coil 3 and a stray capacitance cause series resonance (1st resonance). An antenna conductor 1 has a stray capacitance, and an inductance of a 2nd coil 8 and a stray capacitance mainly cause apparent parallel resonance (2nd resonance). The reception sensitivity at a desired reception frequency band is improved by the two resonance phenomena and made flat. Furthermore, a capacitance of a capacitor 7 shows a low impedance at a high reception frequency band and indicates a high impedance at a low reception frequency band. Thus, a reception signal at a high reception frequency band induced in the antenna conductor 1 is fed to the receiver via the capacitor 7.

Title: Power steering device
Inventor: IJIMA YOSHITAKA
IPC: B62D6/00
Filed: 1990-09-29
Abstract: PURPOSE:To perform stable running responding to a road surface state by detecting the grasping force of a driver in relation to a steering wheel and controlling an assist amount by a power steering device in response to the detecting grasping force. CONSTITUTION:When a vehicle enters an extremely uneven adverse road or an adverse rod, such as a snow road, where a slip is easy to occur, a driver naturally firmly grasps a steering wheel 10. In which case, since a rubber hose 44, injected and sealed with oil, of a gasping force sensor 12 mounted on a steering wheel 10 is strongly pressed, the pressure oil with which the interior is sealed is increased, a pressure value is measured by a pressure sensor 42, and a pressure signal is outputted to a controller 40. The controller 40 also inputs the steering angle of the steering wheel 10 measured by a steering angle sensor 14. When the steering angle is within, for example, 5 deg. on both sides, the drive current of an electric motor 20 is decreased to decrease an assist amount and increase a steering force felt by a driver.
