Title: Breakerless i.c. engine ignition system with electronic advance
Inventor: DYKSTRA RICHARD A
IPC: F02P1/08
Filed: 1992-04-14
Abstract: A generator 4 operating in synchronism with the engine generates current pulses in a winding 5. An ignition circuit connected across the winding includes a power switching transistor 7 connected in series with a collector voltage dropping means 10 to the winding. A bias circuit for the power transistor 7 includes a resistor 12 and is connected to a control switch 8 controlled by a capacitive control circuit 23, 24, 25 connected across the winding 5. The capacitive control circuit operates, via the bias circuit to turn the power transistor 7 off following the peak current in the winding 5, with a delay which decreases progressively with engine speed. Current interruption in the winding generates a high voltage ignition pulse. <IMAGE>

Title: Structure for fixing permanent magnets in motor
Inventor: FUKUI MASASHI
IPC: H02K1/17
Filed: 1992-05-15
Abstract: A fixing structure is disclosed which is capable of fixing permanent magnets (6) to an internal peripheral surface of a cylindrical yoke (8, 12) in a short time without producing a positional deviation. The fixing structure has magnet receiving pieces (12e) which project from the internal peripheral surface of an internal cylinder (12), and magnet holders (13) each having elastically deformable magnet pressure pieces (13A) formed therein, so that arcuate permanent magnets (6) are respectively held between the elastically deformed magnet pressure pieces and the magnet receiving pieces and pressed against the side of the magnet receiving pieces in a normal direction due to the elastic restoring force on the magnet pressure pieces. The permanent magnets can thus be retained against the internal peripheral surface of the internal cylinder. <IMAGE>

Title: Record carrier and eddy current reader.
Inventor: OGAWA TATSUYA
IPC: B42D15/10
Filed: 1993-01-06
Abstract: A method of reading patterned information from a record carrier formed by partially removing a vapor deposited metal layer from the carrier according to a predetermined pattern, wherein it is sensed as a series of eddy current signals by scanning a sensor head which senses the difference in eddy currents between the portion having the vapor deposited metal layer and the removed portion. Thus, the information can be reliably read from the carrier in a non-contact manner, even when hidden by an opacifying layer. The record carrier in the form of a magnetic card C comprises a magnetic layer 2, a vapour deposited metal layer 2, an opacifying layer 4 and a wear-resistant protective layer 5 and a printed layer 6. The metal layer comprises a non-deposited portion 3A and a removed portion 3B forming the information pattern. <IMAGE>

Title: Coin selection device
Inventor: RATZKER HENRY BERTHOLD
IPC: G07F1/04
Filed: 1993-04-05
Abstract: A coin selection device for a vending machine comprises a coin receiving chute, first coin sensing means at an entrance 9 to the chute and second coin sensing means (37, 41) for detecting the presence of correct coinage within the chute. A control circuit of the coin selection device is arranged to respond to signals from the first and second coin sensing means and to operate a coin rejection means if signals are not received from both the first and second coin sensing means within a predetermined period of time. As described a coin entering the device at (9) causes linkage to operate a microswitch (60) to actuate the control circuitry. The coin then falls to a position between sensing means (37, 41) which are in the form of electrical contacts. If the coin (or possibly a plurality of coins) bridges the contacts an acceptance signal is generated thus causing a flap (18) to pivot in a first direction to allow the coins to pass to an acceptance region. If no acceptance signal is generated within a set time of actuating the control circuitry the flap (18) is pivoted in the opposite direction to reject the coin. The device may include a thickness gauge (14) and means to separate parts of the device to release jammed coins. <IMAGE>

Patent GB-2280810-A (GB)
Title: Distance measurement
Inventor: KISE KATSUYUKI
IPC: G01C3/00
Filed: 1994-03-23
Abstract: The system stereoscopically determines the distance of all points within fields of view obtained by cameras 11a, 11b, 12a, 12b. The outputs of the cameras are processed eg to increase contrast 31, 32 and stored 33. Small regions (eg 4 x 4 pixels) of the stored images are compared with various shifts; if the minimum difference exceeds one threshold, the difference between the maximum and minimum differences exceeds a second threshold, and the change in brightness within a region exceeds a third threshold, the comparison is deemed to be valid, and the shift which produces the minimum difference gives the range of the small region. In order to compensate for variations in sensitivity between the cameras, their outputs are also fed to a buffer memory 16. The images are divided up into zones (sky, long-range road, short-range road, left or right of road) and a correction for each zone, based on the average intensity or intensity variation, is obtained; these are summed to obtain a required variation in shutter speed which is used 17 to control the corresponding camera. <IMAGE>

Abstract: The invention relates to a device (2) designed and adapted to bring an in per se known mixing body (11) to correspond to a fluid flow area which e.g. is defined by a pipeline (1, 3) wherein a two-phase fluid may flow, said fluid being desired to be mixed in connection with sampling (4), and to withdraw the mixing body (11) easily and rapidly in order to release said fluid flow area. For this purpose, the 6 device according to the invention comprises a valve housing (6) formed for fluid-tight connection to said pipeline in an area of two diametrally opposite openings (1', 1") of the pipeline, enclosing said openings. Within the valve housing (6), a sluice body (5) carrying said mixing body (11) has been displaceably arranged. The sluice body (5) and thus the mixing body (11) is displaceable between two main positions. In one main position, the mixing body (11) has been brought to correspond with said fluid flow area. In the other main position, the mixing (11), through the sluice body (5), has been drawn into the valve housing (6) to a position wherein the fluid flow area has been uncovered. In the last mentioned main position, a through-going bore (10) of the sluice body (5) can be brought to correspond with the fluid flow area, said through-going bore (10) having a diameter substantially corresponding to the diameter of the flow area of the pipeline (1, 3), downstreams the sluice body (5). <IMAGE>

Title: Device and method of regulating the start of fuel injection in an otto engine
Inventor: GILLBRAND PETER
IPC: F02D41/34
Filed: 1993-06-30
Abstract: The invention relates to a device and a method which can be applied primarily to computer controlled fuel systems for Otto engines, with sequential injection of fuel in each cylinder to the inlet valves. In order to utilize the capacity of the hot inlet valves for evaporating the fuel, in normal operating cases, the invention is characterised in that the start of injection (60) is continuously adapted to the prevailing fuel demand and the injection time consequently required, so that the injection D is substantially completed before the inlet valve A towards which the injector is directed will begin to open (50). The control of the start of injection according to the invention provides, by simple means, improved evaporation of the fuel and more homogeneous fuel-air mixture, which in turn provides a more complete combustion and reduced emissions. <IMAGE>
