摘要： An angular velocity sensor includes a movable bi-directional electrode and a fixed bi-directional electrode wherein L-shaped electrode plates of the movable bi-directional vibration-urging electrode mesh in spaced relationship with L-shaped electrode plates of the fixed bi-directional electrode. In one embodiment in response to a vibration driving signal applied between the electrodes, a vibration plate vibrates with a large amplitude in one direction parallel to the direction in which bent parts of the L-shaped electrode plates extend. If an angular velocity .OMEGA..sub.Z about the Z axis is applied to the vibration plate, the vibration plate is greatly displaced in the Y direction by Coriolis force. This displacement is detected by a displacement detecting part with high accuracy. In another embodiment, the bi-directional electrodes serve as the displacement detecting part.

摘要： A novel slow wave structure capable of ultrabroadband operation includes a meander line of a predetermined length on a layer of insulative material, a first series of spaced metal fingers forming a comb line are attached to the layer and extend in parallel from a front edge of the layer into the facing concave portions of the meander line and a second series of spaced metal fingers forming a comb line are attached to the layer and extend in parallel into the concave portions of the meander line from the opposed back edge of the layer. A metal layer or ground plane is connected to the underside of the layer and both series of metal projecting fingers are placed electrically in common together with the bottom ground plane. In a preferred method of manufacturing of the invention the insulative layer is completely coated or covered with metal on all surfaces and using a photoresist etching process the insulative spaces between the meander lines and the fingers are etched out leaving the desired structure.

摘要： PROBLEM TO BE SOLVED: To provide an electric circuit part having a conductor layer satisfying both an electric characteristic and a mechanical characteristic on a porcelain substrate by constituting the conductor layer of a first conductor layer, an intermediate layer formed on the surface of the first conductor layer and a second conductor layer formed on the intermediate layer in the electric circuit part containing the porcelain substrate and the conductor layer formed on the surface of the porcelain substrate. SOLUTION: Respective conductors are constituted of stacked conductors 23 formed of first and second layers 21 and 22. Conductive paste is applied to the first and second layers 21 and 22 and they are formed of baked layers. When the surface part 21b of the first layer 21 is arranged between an inner part 21a and the second layer 22, the mutual diffusion of solder and conductive particles in the inner part 21a of the first layer 21 is suppressed on the surface part 21b with much glass components, which functions as an intermediate layer, at the time of soldering, and a solder consumed phenomenon can be prevented, Then, the first layer 2 can mechanically be protected by the second layer 22.
