  • Patent number: 5662755
    Abstract: A method of making a multi-layered ceramic substrate which includes the steps of laminating a desired number of green sheets each being made of glass ceramics containing at least an organic binder and a solvent and each having a pattern of electrodes formed thereon by the use of an electroconductive paste, to thereby provide a green sheet laminate, The electrodes on opposite surfaces or an entire surface layer of the green sheet laminate are subsequently printed with a paste comprising an inorganic component added with at least an organic binder containing a Zn composition. On each surface of the laminate printed with the paste of the Zn composition, a green sheet made of an inorganic composition incapable of being sintered at a temperature of crystallization of the glass ceramics is then laminated thereby providing a laminate plate which is subsequently fired.

  • Patent number: 4740002
    Abstract: The rear wheels of a vehicle are turned together with the front wheels in response to the operation of a steering wheel. Turning ratio changing means is provided so as to be able to change a turning ratio of the rear wheels to the front wheels. In altering the turning ratio, a speed of changing the turning ratio is designed to get delayed when a road surface is more slidable or slippery, i.e., a road surface friction coefficient .mu. is smaller, as compared to when a road surface is less slidable or less slippery, i.e., a road surface friction coefficient .mu. is larger.

  • Patent number: 4719981
    Abstract: A four-wheel steering system for a vehicle comprises a steering wheel, a front wheel turning mechanism for turning front wheels in response to operation of the steering wheel, and a rear wheel turning mechanism which turns rear wheels in response to operation of the steering wheel and is provided with an electric actuator for changing the position of a movable member the position of which determines a rear wheel turning angle ratio which is the ratio of the turning angle of the rear wheels to the turning angle of the front wheels for a given turning angle of the steering wheel. A control circuit receives a vehicle speed signal from a vehicle speed sensor and controls the electric actuator according to the detected vehicle speed so that a target rear wheel turning angle ratio determined in advance according to the vehicle speed is obtained. A preset vehicle speed detector detects a preset vehicle speed and a rear wheel turning angle ratio detector detects the actual rear wheel turning angle ratio.
