Abstract: A product having a glass layer is produced that can be produced at low cost and can exhibit excellent antibacterial function. A base body, a first glazing material capable of forming a first glass layer on a surface of the base body, and a second glazing material capable of forming a second glass layer containing a silver compound on the surface of the base body. A first glazing material layer comprising the first glazing material and, on the surface side, a second glazing material layer comprising the second glazing material are formed on the surface of the base body. The first glazing material layer and the second glazing material layer are melted to form a first glass layer and a second glass layer. The second glazing material layer has a higher viscosity upon melting than the first glazing material layer.

Abstract: A system having a motor operatively connected to a steering system for reducing the steering effort. The system is provided with a torsion torque sensor provided for detecting torsion torque generating in the steering system in steering operation. In response to the output signal of the torsion torque sensor, an assist signal is produced. The system has a dead zone for the output signal of the torsion torque sensor. Only when the output signal exceeds the dead zone, the assist signal is produced to operate the motor.

Abstract: An electric power steering system has a torsion torque sensor provided for detecting torsion torque generating in a steering system of a motor vehicle, for providing an assist signal for driving a motor to turn a steering wheel. A steering angle sensor is provided for detecting steering angle of the steering wheel and for producing a steering angle signal. In response to the steering angle signal, a return torque signal is produced for steering wheel. A vehicle speed sensor is provided for producing a vehicle speed signal dependent on speed of the vehicle, and a calculator is provided calculating lateral acceleration impared to the vehicle and for producing a lateral-acceleration-dependent-return torque signal. In accordance with the vehicle speed signal, the lateral-acceleration-dependent-return torque signal is corrected to produce return torque correcting signal, the absolute value of which reduces with increase of vehicle speed.
