Title: Bit synchroniser for nrz data
Inventor: LEE BHUM CHEOL
IPC: H03L7/089
Filed: 1993-03-17
Abstract: A bit synchronizer for NRZ data wherein a loop gain of a phase locked loop in the bit synchronizer is not varied sensitively to bit pattern and rate of the NRZ data and a voltage controlled oscillator in the bit synchronizer oscillates synchronously with a multiple of a frequency of an external reference clock pulse oven in the absence of NRZ data transitions or over a wide range of variation of a clock frequency of the voltage controlled oscillator, so that the NRZ data and clock can be recovered stably. According to the invention, the bit synchronizer comprises a phase comparator (21), a first gain controller (22), a frequency comparator (23), a second gain controller (24), a N-frequency divider (25), a low pass filter (26) and a voltage controlled oscillator (27). The first and second gain controllers limit the gains of the place and frequency comparators, respectively, to predetermined values. <IMAGE>

Title: Ultrasonic transducer
Inventor: TURNER CHARLES WILLIAM
IPC: B06B1/06
Filed: 1993-03-25
Abstract: The transducer comprises a thin conical membrane 1 fixed at its open end to a piezoelectric disc 2 and produces acoustic radiation from the vibrating membrane into the adjacent fluid medium along the axis of the cone. The transducer is capable of operation in air at ultrasound frequencies well above 100 KHz both as a transmitter and a receiver. The piezoelectric disc operates in the radial mode. The conical membrane enclosed angle is chosen to ensure that the radiated ultrasound beam is directed in the desired manner, e.g. as a focussed beam, a divergent beam or as a collimated beam. A tuning inductance is connected electrically at the input terminals to ensure maximum efficiency. <IMAGE>

Patent GB-2302921-A (GB)
Title: Labyrinth and magnetic seal
Inventor: BROOKS DOUGLAS ALAN
IPC: F16J15/43
Filed: 1995-07-04
Abstract: The seal is made up of a combination of two components. A labyrinth arrangement, and a magnetic circuit arrangement. The labyrinth arrangement having a gap 7 can, of itself, form a barrier to ingress of particulates or fluids. It can also be packed with grease to enhance this capability. The magnetic circuit is designed to entrap a magnetic fluid and has pole-pieces 2 and a magnetically permeable sleeve and provides a virtually hermetic rotating seal. This part of the seal relies on: the ability of this trapped fluid to withstand a small pressure differential and to be impervious to all gases including helium, and, the buoyancy effect induced by the magnetic fluid on non-magnetic particles, effectively expelling them from penetrating the magnetic field.

Title: Passing programming constructs across a foreign interface
Inventor: CHESSELL AMANDA ELIZABETH
IPC: G06F15/16
Filed: 1997-08-28
Abstract: Passing information, such as an object or other programming construct, between two computer software applications 11, 13, which would usually communicate through a language independent interface 12. Sending application 11 sends an item of information to be transferred to a memory store such as a cache 14, without first converting the information to the neutral interface language. A token uniquely representing that item of information is returned to the sending application 11, and then passed through interface 12, where it is converted to the neutral language, and received by receiving application 13 which converts the token back to its native language. Receiving application 13 uses the token to access the information stored in store 14. Processing load is reduced since, despite the presence of the language independent interface 12, the information to be transferred need not be converted to language neutral form.

Title: Phase detecting method of a digital vestigial sideband modulation communication device
Inventor: LEE MYEONG-HWAN
IPC: H04L27/00
Filed: 1996-04-17
Abstract: A phase detecting method of a digital vestigial sideband modulation communication device has the steps of: digital-filtering I channel data applied from the exterior to restore Q channel data; compensating for a phase of the I and Q channel data by a prescribed phase error value; estimating an I channel level value which approximates to the I channel data from the phase-compensated I channel data; and obtaining a difference between the phase-compensated I channel data and the estimated I channel level value, and generating as the phase error value an operation value obtained by multiplying the difference by a sign of the Q channel data. The phase error is optimised by non-linear processing involving elimination of an isolated point.

Title: Radio signal receiving apparatus with audio signal receiving and reproducing function
Inventor: BANNO SATOSHI
IPC: H04B1/16
Filed: 1997-10-23
Abstract: In a radio signal receiving apparatus with an audio signal receiving and reproducing function, if a message signal is received by a receiver 2 from an external device when an accompanying sound reproducer 10 is in use, the sound volume of a signal from the sound reproducer 10 is automatically changed continuously by a variable amplifier 9b to a prescribed non-zero value. An audio signal from the message receiver is mixed in a circuit 7 with the audio signal of which the sound volume is changed to be supplied to a loudspeaker 8. In this construction, even if an external message sent is fed to the receiver 2 when the sound reproducer 10 is in operation, the sound of the message signal can be produced without interrupting the output operation of the audio signal from the sound reproducer.
