An organic EL device in the present invention comprises a light-transmissive substrate, an organic light emitting layer, a light-transmissive electrodedisposed between the light-transmissive substrateand the organic light emitting layer, and a light guiding layerwhich is disposed between the substrateand the light-transmissive electrode. The light guiding layeris configured to alter light direction. The organic EL device is configured to emit light from the organic light emitting layer, and allow the light to propagate out through said light guiding layer, the light-transmissive electrode, and the light-transmissive substrate. The light guiding layerincludes a light dispersion layer. The light dispersion layeris formed with a light dispersion regionand a light-transmissive region, which are arranged in a coplanar relation within said light dispersion layer. The light dispersion regioncontains light dispersion particlesand a binder resin. The light-transmissive regioncontains the light dispersion particlesat a lower ratio than the light dispersion region. The organic EL device in the present invention enables to improve an overall light output by suppressing the reduction of light output in the front direction as well as increasing light output in diagonal directions.

A position sensor with excellent linearity of coil impedance is provided. This position sensor is equipped with a tubular detection coil, a magnetic core movable in the detection coil, a drive circuit for the detection coil, a signal processing circuit for converting a change in impedance of the detection coil into an electric signal, and a shield member disposed around the detection coil. The shield member is a tubular member having a first inner surface for surrounding an axial region of the detection coil, and a second inner surface for surrounding another axial region of the detection coil. The tubular member is formed such that a distance between the second inner surface and the detection coil is smaller than the distance between the first inner surface and the detection coil.

An actuator includes a casing, a stationary member having a coil member and mounted in the casing and a movable member having a moving element and supported by the casing. The moving element has a shaft and is supported by the casing so as to be moved in an axial direction of the shaft and in a rotational direction having the axial direction of the shaft as its rotational axis and the moving element is moved in the axial direction and in the rotational direction by causing electric current to flow through the coil member. The stationary member includes a first stationary member for imparting to the movable member a force oriented in the axial direction and a second stationary member for imparting to the movable member a force oriented in the rotational direction, while the coil member includes a first coil member for exciting a first magnetic path passing through the first stationary member and a second coil member for exciting a second magnetic path passing through the second stationary member.
