Title: Magnetic recording and reproducing device
Inventor: OSAWA TOSHIO
IPC: G11B21/02
Filed: 1985-03-08
Abstract: PURPOSE:To prevent the occurrence of azimuth and the reduction of output by arranging a guide material, which is used as the guide for movement of a carriage to which a magnetic head is set, near a line extended from a gap position for magnetic head recording and reproducing in the direction of the revolving shaft of a medium. CONSTITUTION:A slide part of the guide material where the carriage is slided is arranged near the line extended from the gap position for magnetic head recording and reproducing in the direction of the revolving shaft of a disc. Though coefficients of expansion of the carriage 2 and a chassis are different from each other, the relative position of a gap for magnetic head recording and reproducing to the chassis in the direction perpendicular to the normal of a rotation center 6 is hardly changed by the variance of temperature. Since it is necessary that the reduction of output by azimuth is <=0.5%, it is necessary that (n) is smaller than 0.235R when the track width is >=165mum and the line recording density is >=70kBPI.

Title: Method for receiving selective call signal and receiver
Inventor: SAKA NOBUAKI
IPC: H04W84/02
Filed: 1995-03-06
Abstract: PURPOSE: To attain reception immediately after the recovery of a disturbance by detecting simultaneously a synchronizing code and a preamble even when the disturbance takes place during reception. CONSTITUTION: When a preamble detection circuit 3 detects a preamble from an output of a reception circuit 2, the detection circuit 3 sends a reset signal to a counter circuit 6, which is reset. Then an output of the circuit 6 activates a synchronizing code detection circuit 4 via a 1st timing generating circuit 7. When the synchronizing code of the circuit 4 is detected, the detection output activates a call code detection circuit 5 via a 2nd timing generating circuit 8 to make detection. When a signal is tentatively interrupted on the way of reception and the circuit 4 does not detect the synchronizing code, the circuit 4 stops an output of the circuit 8 to inactivate the circuits 2, 5 but the circuit 6 continues its operation, then the circuit 7 continues the operation.  Thus, the circuits 2, 3, 4 are active and then have provision for recovery of disturbance and arrival of new preamble immediately while being synchronously with the transmission signal having been so far received.
