    摘要: A dielectric filter in which input/output coupling electrode layers are arranged on the surfaces of the substrate sections, separated from the resonating conductors by an adjustable distance, the coupling capacitance of the device can be chosen within a wide range of selection because of the relatively large area of the surfaces. The dielectric filter comprises an interstage coupling electrode layer which is formed on a temporary surface of a dielectric substrate that has a relatively large area and becomes internal in the final product with a predetermined but adjustable distance from a pair of resonating conductors arranged in the dielectric substrate.

    摘要: A method of and a system for controlling a hydraulic shock absorber of an automobile are provided. In the shock absorber, a flow of damping fluid induces a load on an actuator of the shock absorber during bouncing and rebouncing of the shock absorber, and the actuator is actuated in response to an output signal of a control unit. In order for the actuator to counteract the load applied thereto, the output signal is modified in response to the load. According to the embodiment, the load is determined by a table look-up operation based on an input load detected by a load sensor mounted to the automobile.
