Title: Driver circuit for light emitting elements
Inventor: KADOTA DAISUKE
IPC: H04B10/564
Filed: 1994-05-26
Abstract: A driver circuit, particularly for the light emitting elements of an optical amplifying repeater, maintains power to the remaining operational light-emitting elements LDm when one or more of a series of light-emitting elements has a disconnection fault. The elements may be laser diodes. The driver circuit has series-connected multiple light-emitting elements LD1  SIMILAR  LDn, connected to a constant-current power source and a corresponding emitted light power control circuit 1 for each of the light-emitting elements. Each control circuit 1 has a bypass current control element 2 connected in parallel to the corresponding light-emitting element, LDm a light-receiving element 3 detecting the light emitted by the associated light-emitting element LDm, a current control circuit 4 controlling current flowing through the bypass current control element 2 in accordance with the light receipt level and a voltage detecting circuit 5 which increases the current flowing to the bypass current control element 2 when the voltage between the terminals of the corresponding light-emitting element LDm reaches or exceeds a fixed voltage value. <IMAGE>

Inventor: COCKBURN IAN
IPC: G01B5/24
Filed: 1994-09-03
Abstract: The angle measuring apparatus, comprises jaws 11 and 12 which are pivotally mounted, by means of hinges 11a and 12a respectively, on an elongate fixed member 13. The fixed member 13 comprises upper and lower portions 13a, 13b between which is slidably mounted an elongate actuating member 14. The jaws 11 and 12 are respectively connected pivotally to first ends of linkage members 15 and 16 at regions remote from their respective hinges 11a and 12a. The linkage members 15 and 16 are pivotally connected at their second ends to the slidable actuating member 14.

Title: Noise-excising Communications Receiver
Inventor: LATHAM NICHOLAS HUGH JAMES
IPC: H04B1/10
Filed: 1995-08-03
Abstract: A receiver extracts a wanted VLF signal from a wide signal band also containing unwanted signals and impulsive noise. Analyser 103 identifies the most powerful unwanted signals and sets mix frequencies for unwanted signal removal and noise excision stages 202, 203, 204. Each stage detects noise above a threshold level, set above the mean signal band power, excises the noise, patches the signal and removes the unwanted signal. The wanted signal is extracted by final stage 205. Unwanted signals are removed in decreasing order of power. The analyser may use a spectral analysis (FFT) technique on blocks of the received signal.

Title: Five valve manifold for use with a pressure sensing apparatus
Inventor: HUTTON PETER B
IPC: F16K27/02
Filed: 1994-03-02
Abstract: A five valve manifold for use with a pressure sensing apparatus is disclosed. It has an integral body having a first face, a second face, parallel with the first face. A peripheral wall section, spans the distance between the first and second face sections. The distance is smaller than at least one of the width and the length of the second face section. A passage system within said body and includes a pluarlity of mutually intercommunicating passages extending from one said face to the other. A set of five valves operates selective opening and closing of the passages. The centres of the instrument outlets at one face are suited to new type of "smart" pressure transmitters, while the inlet ports at the other correspond to the usual spacing used in the industry. The invention eliminates the use of a so-called parallel flange used by the manufacturers of pressure transmitters to accommodate the difference in the centres of connecting ports of the instrument from that previously used by the industry. The device is also provided with an arrangement which facilitates the venting of entrapped air. <IMAGE>

Title: Cylinder cut out control system
Inventor: MORIKAWSA KOJI
IPC: F02D41/00
Filed: 1996-06-21
Abstract: In a two cycle direct injection engine, fuel injection 6 and ignition 7 in a cylinder is cut out with a frequency that reduces as the engine load increases when the engine speed 31 and target load 10 indicate that the engine is operating a cylinder disable region where misfires might occur. The frequency with which the operation of a particular cylinder is suspended can be controlled independently to ensure that it is not always the same cylinder that is disabled. The map 35 can be adjusted according to the detected fuel properties, if the engine continues to misfire or to compensate for cooling of a cylinder following a suspension of its operation.

Title: Apparatus for pressing a recording head to a transfer roller in an image reproduction apparatus
Inventor: BAE CHI-WAN
IPC: B41J2/315
Filed: 1996-07-31
Abstract: A facsimile system is disclosed which comprises a recording head 12, a roller 10 capable of transferring sheets of recording paper to the recording head 12 and an elastic body 16 capable of pressing the recording head 12 and roller 10 into contact with one other at a prescribed pressure when in an elastically deformed state. A first frame portion 28 includes a rib 30 which engages a hole 18 in the elastic body 16 to prevent it from moving in two dimensions. A second frame portion 24 includes a projection 26 which overlies the elastic body 16 and prevents its motion in the remaining direction. The rib 30 and projection 26 thus retain the elastic body 16 when it is in the elastically deformed state, but they allow the elastic body 16 to be detached either by a twisting movement of the elastic body 16 when it is in a relaxed state or by detachment of the two frame portions 24, 28 from one another.
