Patent GB-2186139-A (GB)
Title: Phase and quadrature receiver
Inventor: SAUL PETER HENRY
IPC: H03D1/22
Filed: 1986-01-30
Abstract: A broadband receiver comprising two pairs of signal mixers (M1 and M2, M3 and M4), a summing node (???) and a subtracting node ( DELTA ). High frequency input signal is applied to one pair of these mixers (M3, M4) and a quadrature phase related input signal is applied to the other pair (M1, M2). Quadrature phase related reference local oscillator signals are applied to the mixers of each pair (M1 and M2; M3 and M4). In-phase mixer product signals are subtracted at one node ( DELTA ) and quadrature phase mixer product signals are summed at the other node (???), eliminating higher order product terms, and obviating need for critical matched low-pass filtration. The receiver may be implemented using analogue and/or digital components. <IMAGE>

The control 34 may be operated by hand or foot or in response to detection of the motion, voice or eyelid movement of the user. Control 34 may be linked to the power control circuitry by power line carrier transmission, optical fibre, a telephone system or a wireless link, one or two photosensors may be used to control ambient light level or ambient/local contrast. An interface 42 for use with a fluorescent light fitting has a plug (50), (Figs. 5,7)) to engage a power supply socket, a socket (46) to receive a plug (48) connected to the fitting, and is connected to a remote user control 34.

Title: A radio communication system
Inventor: KOBAYASHI HIDEO
IPC: H04J3/10
Filed: 1988-08-23
Abstract: A radio communication system with improved interference rejection characteristics has a frequency division multiplexed transmission signal of a plurality of sub-signals C5 formed by carrier signals (f1000 fn) of different frequency each modulating a common signal data signal. On a receive side, these signals are coherently detected, and the detected signals are combined. The combined signal is the arithmetical sum of each of the sub-signals, whilst the combined noise is the power sum of the noise in each sub-signals. Therefore, the carrier to noise ratio is improved. The receive side may select and combine only some of the detected signals to optimise the carrier to noise ratio, for example omitting carriers f3, fn-1 which are coincident with interference I1, I2. <IMAGE>

Title: Window system synchronising protective circuit
Inventor: ITOI SATOSHI
IPC: H04L7/08
Filed: 1988-11-25
Abstract: The circuit (11) has a window forming circuit (12) forming windows having a predetermined position which detect the forthcoming synchronizing signal (B) in accordance with a counted value of bit clock pulses produced by a bit clock (2). The window forming circuit forms a window corresponding to a predetermined number of bit clock pulses before and after detecting a synchronizing signal. The window forming circuit generates a window signal (F) (Fig 2). A protective synchronizing circuit (13) which receives the detected synchronizing signal (B) and the window signal (F) generates a protective synchronizing signal (L) which has a phasic relation to the detected synchronizing signal. If no synchronizing signal has been detected in the windows then the protective synchronizing signal is output. If the synchronizing signal has not been detected after a predetermined period a window reset circuit (14) changes the position of the windows.

Filed: 1990-02-15
Abstract: A tape tensioning device for a tape recorder which automatically eliminates possible slack in a tape within a tape cassette in response to loading of the tape cassette and without necessitating any additional manual operation. Upon loading of a tape cassette (5), a tape feeding motor (9) is energized by way of a cassette detecting switch (6) and a tape tensioning motor switch (8) to start its rotation, and the rotation is transmitted to a specific one reel spindle (2a) by way of a tape tensioning rotation transmitting means (25) while the other reel spindle (2b) is inhibited from rotation by a brake means (16), thereby absorbing possible slack in the tape (5b) to tension the tape (5b). A tension detecting means (37: 37a) detects the tensioned condition of the tape (5b) to move a controlling member (11) away from its home position to disconnect the tape tensioning rotation transmitting means (25), cancel the braked condition and switch the tape tensioning motor switch (8) off to deenergize the tape feeding motor (9) to stop rotation of the motor (9). <IMAGE>
