    摘要: A multilayer inductor includes first and second conductive coil patterns which are disposed in two layers in an upper portion of a multi-layered body and are electrically connected consecutively in series to third and fourth conductive coil patterns disposed in a lower portion of the multi-layered body through via-holes formed in an insulation sheet, thereby forming a spiral coil. The first conductive coil patterns and the second conductive coil patterns overlap each other at edges thereof. The fourth conductive coil patterns and the third conductive coil patterns overlap each other at edges thereof.

    摘要: A wet friction member which can maintain boundary lubrication by decreasing the thickness of oil film on a friction surface even when the sliding velocity increases. In a case where the friction surface of the friction member is in pressure contact with a mated member while rotating in a state of boundary lubrications a shearing resistance owing to viscosity of cooling oil is circumferentially applied to cooling oil in outer grooves in the friction surface. Since outer grooves extend from starting position of intermediate portions of the friction surface and terminate at the outer peripheral edge in a volute shape toward the direction of rotation, cooling oil in the outer grooves flows along the groove walls and is quickly discharged from opening portions at the outer peripheral edge.

    摘要: A ceramics circuit board is manufactured by preliminarily preparing a circuit pattern base composed of a plurality of circuit pattern elements connected by bridging pieces each having a thickness smaller than that of the circuit pattern element, preferably less than half thickness of the circuit pattern base, applying and bonding the circuit pattern base onto one surface of a ceramics board base and removing the bridging pieces by effecting an etching treatment to thereby form a circuit pattern having a predetermined shape on the one surface of the ceramics board base. The circuit pattern base and the bridging pieces are formed of one metallic plate by partially effecting etching treatment. The bridging pieces are arranged so as to have a gap between a rear surface thereof and the one surface of the ceramics board base when the circuit pattern base is applied on the one surface of the ceramics board base. The bonding step may be carried out by forming, on a surface to be bonded, an eutectic material composed of the same metallic material as that composing the circuit pattern base and oxygen. It is preferred that the method further includes the step of applying and bonding a copper plate to another surface of the ceramics board base before the etching treatment.
