A record carrier includes a pattern of substantially parallel tracks for storing data in the form of marks, in which the data is encoded by a channel code. A second control signal bus line receives a second control signal that lags behind the first control signal. For example, a topical administration may contain between about 50 pgml drug to about 50 \u03bcgml drug in a formulation which may be applied at bedtime or throughout the day. According to the spin polarized ion scattering spectroscopy apparatus, the spin status in a region at a depth of about 2 to 3 atomic layers from the surface of the specimen can be measured while discriminating the elements from the atomic layer with a reduced measurement time and with a high accuracy impossible in the conventional technique. In one embodiment, the receiver and method for weight detection may be suitable for use in closed loop diversity mode communication systems, including a Wideband Code Division Multiple Access system. More specifically, the present invention relates to methods for determining a dive angle for grain.
