Patent GB-2307316-A (GB)
Title: Switching power supply apparatus
Inventor: HAYASHI HIROSHI
IPC: H02M3/156
Filed: 1996-10-23
Abstract: The apparatus comprises a switching transistor Q1 and an inductance coil L connected in series between input and output terminals. A Zener diode ZD and a resistor R3 are connected in series between the output terminal and ground. When the voltage across the resistor exceeds a predetermined value, the switching transistor is rendered non-conducting by a drive circuit Q2. The drive transistor Q2 is connected between the base of the switching transistor and the output terminal. A diode D1 provides a path for current resulting from a back emf that is developed in the inductance coil when the switching transistor is rendered non-conducting. Overcurrent protection is provided by a resistor R4 and transistor Q4. A second diode (17, Fig.6) may be connected with its cathode connected to the cathode of the diode D1 (18) and its anode connected to the base of the drive transistor Q2 (14) in order to keep the switching transistor in its non-conducting state until the back emf developed in the inductance coil becomes too small to maintain a forward voltage of the diode D1 (18). In this case, the drive transistor (14) is connected in series between the base of the switching transistor and ground.

Title: Rotor support with one or two pairs of permanent magnetic bearings and a pivot
Inventor: ISHIZUKA KACHU
IPC: F16C39/06
Filed: 1999-02-25
Abstract: A bearing structure has one or two (figs 2, 5) pairs of axially spaced permanent magnetic bearings 3, 4 for radially supporting a rotor 1 at two supporting points in a non-contact manner. Thrust forces F1, F2 of each magnetic bearing in a pair act in opposite axial directions and a pivot 5a on an axis 7 of the rotor 1 bears a shaft end 5b of the rotor 1 when the shaft end 5b is displaced in an axial direction from the neutral position where all thrust forces acting on the rotor balance. The magnetic bearings 3, 4 may attract or repel (figs 4-6) and be orientated axially or radially (figs 4-6) of the rotor 1. To cope with excessive rotor displacements in both axial directions, a further stop 6 (8 fig 4) or second pivot (figs 7, 8) may be used. Stop 6 may also space the magnets 4a, 4b to prevent sticking. Two pairs of magnetic bearings may be concentric (fig 2). The rotor may be for a motor, fan or polygonal mirror.
Patent GB-2347831-A (GB)
Title: Synchronisation in digital data transmission systems
Inventor: BURTON MARK
IPC: H04B7/26
Filed: 1999-03-06
Abstract: Synchronisation burst decoding is improved by making use of the auto correlation property of a subset of the training sequence. The sequence of received symbols in a subset of the training sequence is more temporally localised than the full set of training sequence symbols. Cross correlation of a subset of the received training sequence with the expected training sequence provides an initial channel estimate and a frequency error estimate (4). The frequency error estimate is used to correct the frequency of the synchronisation burst (5) before equalisation using the complete training sequence (6).

Date Dec. 7, 1995A radio range finding system includes a radio range finder and a plurality of remote mobile transponders. The radio range finder transmits a signal modulated with an address code identifying a particular mobile transponder. When a mobile transponder receives the modulated signal Ms transmitted by the radio range finder and the modulated signal has been modulated with an address code that corresponds to the address assigned to that mobile transponder, the mobile transponder transponds a return signal Rs to the radio range finder. A receiver in the radio range finder conveys the received signal to a mixer which also receives an internal carrier signal identical to the modulated signal output by transmitter. The output of the mixer is then filtered and demodulated to yield an output signal proportional to the distance between the mobile transponder and the radio range finder.
