Abstract:
When there exist two X coils that generate voltages of the same values during the X coil-scan operation (yes in S314), the CPU 56 discards the position coordinate table 58a that is already stored in the work area, and reloads a new position coordinate table 58a from the ROM 58, and then stores the position coordinate table 58a in association with the pen attribute data that is detected in S310. Then, the CPU 58 calculates a ratio r between the detected value d and the reference value g in S318, and multiplies, with the ratio r, each voltage difference value DIFF in the reloaded position coordinate table 58a in S320. As a result, the position coordinate table 58a is corrected in correspondence with the lowering of the output level of the alternating magnetic field of the pen 60. The CPU then calculates the X coordinate based on the corrected position coordinate table 58a.
Abstract:
A wireless communication system capable of communicating by a frequency hopping method, having a base unit that can be connected to an external telephone circuit and multiple handsets that can communicate wirelessly with the base unit. The system generates predetermined hop frequency data In sequence, which is used to transmit and receive signals. The base unit transmits control signals to all the handsets at predetermined intervals, while the handsets transmit control signals to the base unit one by one at predetermined intervals. In this way, the exchange of control signals between the base unit and multiple handsets can be performed more quickly than when the base unit sends control signals to each handset one by one in order to match the individual receiving frequencies of those handsets.

An optical data storage medium having a substrate, and an optical storage layer with a recording track or tracks for storing information to be read by a light beam. An interference layer is formed on the substrate, such that a tracking reflector defining the recording track or tracks is formed on the interference layer. A flattening layer is formed on the interference layer such that the flattening layer covers the tracking reflector and provides a flat surface on which the storage layer is formed. Each of the interference and flattening layers has a thickness substantially equal to 80 /8 or (.lambda./8+m.multidot..lambda./2), where .lambda. represents a wavelength of the light beam as measured while the light beam is travelling through the interference and flattening layers, and m represents a natural number.
Abstract:
A magneto-optical memory medium of a laminar structure comprising at least one non-magnetic layer, and a plurality of magneto-optical storage layers separated from each other by corresponding non-magnetic layers, and wherein information is read out from a selected one of the storage layers by detecting a change in the Kerr rotation angle of a corresponding one of light beams of different wavelengths applied to the memory medium, which change depends upon magneto-optical anisotropy of the storage layers. A thickness of one of the storage layers is determined so that the change in the Kerr rotation angle of each of the light beams repesents the anisotropy of the corresponding storage layer, irrespective of the anisotropy of the other storage layers. Also disclosed is a magneto-optical apparatus for writing and/or reading information on or from the desired magneto-optical layers.
