Abstract: A printing medium has information printed thereon in the form of a bit pattern of dots. The arrangement of those dots is determined by an array of dot sites (1a), some of which correspond to information bits (logic "1") and some (1b) to space bits (logic "0"). If ink dots of a small size (e.g. dimensions (Pd) less than 50µm) are printed, there is the risk that the ink will spread so as to make the dots difficult to identify clearly, and hence, make the information difficult to read. Therefore spaces (Ps) are defined between the dot sites, which spaces are large enough (at least 2µm) to prevent liquid ink at one dot site spreading to another dot site. Hence the information is easier to read. Edge markers (2a,2b) may be provided to define the scanning of rows and columns of the dots, and the dots may be printed in more than one colour, or with more than one size or with more than one density, to measure the information thereof.

Abstract: A method of processing information in an artificial neural network comprising a plurality of artificial neurons (1a to 1n) and weighted links (2) coupling the neurons. In the method, those of the artificial neurons (1a to 1n) whose output values change by a value greater than a threshold value (T) are selected. The output values of the selected neurons are calculated, and the influence which the changes in the output values of the selected neurons impose on the input values of the other artificial neurons is computed. The threshold value (T) is changed such that an appropriate number of neurons are selected. The information processing in the artifi­cial neural network is stopped when the threshold value decreased below a predetermined small value and the values output by all artificial neurons change by a value equal to or less than the threshold value.

The rope engaging surfaces are mounted in a frame (10) so as to be moveable in relation to each other such that a force applied to the rope engaging surfaces (18,19) and acting in one direction of the rope passageway will tend to move the rope engaging members (16,17) closer to each other towards a locking position, while a force applied to the rope engaging surfaces (18,19) and acting in the opposite direction of the rope passageway will tend to increase the spacing of the rope engaging surfaces and to move the rope engaging members towards a releasing position. At least one (16) of the rope engaging members (16,17) is connected to an operating handle (31) by means of a lost motion connection (34,35). When the operating handle is moved from an inactive position to an active position the rope engaging members (16,17) are moved to their releasing position. A releasable retaining member (42) is connected to said at least one rope engaging member (16) and is adapted to retain the rope engaging member (16) in relation to the frame (10) in said releasing position. The operating handle (31) may then be moved back into its inactive position, while the rope engaging members are retained in their releasing position. When it is desired to lock or grip the rope (20) the retaining means (42) may be released.

Abstract: A distance measuring device using two kinds of modulation frequencies (frequency f₁, frequency f₂) is disclosed. More particularly, the distance measuring device is an electro-optical distance meter for measuring a distance by combining the results of fine measurement and rough measurement. The fine measurement is effected by detecting a phase difference between a modulation signal generated from a light emitting device (4) and a reflected modulation signal generated from a light receiving device (5), while the rough measurement is effected by measuring a lag time between the modulation signal and the reflected modulation signal. Further, the distance may be measured by detecting a phase difference and a lag time of a multiplex modulation signal, in which the measurements of the phase difference and the lag time may be carried out in parallel with use of a single frequency. Particularly, a measuring time can be shortened as compared with that in an electro-optical distance meter time-divisionally using three frequencies.

Abstract: A storage medium, such as a rotatable disk having a signal-storing magneto-optic layer, stores a large plurality of data records in a plurality of tracks. The erasure status of portions of each track is indicated by an erasure indicator (E) located between two predetermined data records in each track. The erasure indicator indicates the erased status between a last data record in each track and the end of the track when moving in a direction of recording signals on the storage medium. The erasure indication points to an area of the track separated from the erasure indicator by the last data record of the track, i.e. a predetermined portion of the track remote from the erasure indicator. The recorder operative with a magneto-optic storage medium requires that the area of the storage medium to be written to be erased before writing or recording can occur; this requirement is termed "pre-write erasure" requirement.

Abstract: In a process for forming field oxide regions (40) between active regions in a semiconductor substrate (10), pad oxide, polysilicon and first silicon nitride layers (12,14,16) are successively formed over substrate active regions. The first nitride layer (16), polysilicon layer (14), pad oxide layer (12) and a portion of the substrate (10) are then selectively etched to define field oxide regions with substantially vertical sidewalls (21). A second silicon nitride (32) is provided on the substantially vertical sidewalls (21), and field oxide (40) is grown in the field oxide regions. The first silicon nitride, polysilicon and pad oxide layers (16,14,12) are then removed. The employment of the polysilicon layer (14) prevents the exposure of corners (44) between the field oxide (40) and active regions if an overetch occurs during the removal of the pad oxide layer (12).
