摘要： A filter element has an upstream-side filter layer and a downstream-side filter layer. The downstream-side filter layer is attached to the upstream-side filter layer. A non-woven fabric made of resin fibers formed by a spinning process constitutes the upstream-side filter layer. The resin fibers have an average diameter within a range of 2.5 μm and 10 μm. The non-woven fabric has a weight per unit area within a range of approximately 2.5 g/m2 to 15 g/m2. The downstream-side filter layer has a finer mesh than the mesh of the upstream-side filter layer.

摘要： A filter element has an upstream-side filter layer and a downstream-side filter layer. The downstream-side filter layer is attached to the upstream-side filter layer. The upstream-side filter layer has a coarser mesh than the mesh of the downstream-side filter layer. The upstream-side filter layer has a plurality of through-holes formed therein and extending throughout the thickness of the upstream-side filter layer. The plurality of through-holes allows the filter element to continue to be used when the rest of the upstream-side filter layer is clogged and the downstream-side filter layer still possesses filtering capability.

摘要： A speed detector for detecting the speed of a moving body is of the type including a magnetic core, a detection coil wound about the core, a magnet with one pole thereof faced toward the periphery of the detection coil with a definite air gap therebetween, and means for relatively moving the magnet with respect to the core and the coil in accordance with the movement of the moving body. the magnet is arranged such that the magnetic flux produced thereby crosses the detection coil two times, thereby inducing a direct current voltage in the detection coil having a magnitude proportional to the speed of movement of the moving body and a polarity depending upon the direction of movement thereof.
