Abstract: A system for inspecting a condition of parts (102) packaged on a printed-circuit board (101). The inspection system includes a position detecting device (114,115) to receive scattered light due to illumination of the printed-circuit board with a laser beam and convert the received scattered light into a position signal. This position signal is used for obtaining luminance data and at least two height data of the parts on the printed-circuit board. Proper height data of the parts is determined on the basis of the difference between the two height data. The inspection system determines the package condition by comparing the final height data with a predetermined reference data.

Abstract: A lock which is adapted to transduce the code from a key by electronic means is constructed to resemble the form and functionality of a conventional mechanical cylinder lock. A main casing 1 houses the bolt 3, a rotatable thrower or cam for retracting the bolt, an electro­mechanical release mechanism which normally blocks rotation of the thrower, and a processor to control the release mechanism in response to the detected key code. The electronic reading means are located in association with the keyway 26 of a rotatable barrel 25 in a cylinder unit 19 manufactured as a separate unit from the main casing 1. The thrower and barrel 25 have respective cooperating mechanical couplings 36/37 and the main casing 1 and cylinder unit 19 have respective cooperating electrical connectors 34/33. The lock is therefore assembled by attaching the cylinder unit 19 to the outside of the main casing 1, thus establishing a rotary driving connection from the barrel 25 to the thrower and establishing an electrical connection from the key reader to the processor.

Abstract: A digital filter (10) for prewhitening digital noise is realized without the need to perform multiplication or division operations to weight any of the digital samples. Instead, the data samples that need weighting are bit shifted to achieve multiplication or division by a power of two. In the preferred embodiment, the filtering function is 1-z/8, where z is a single sample delay. This function is implemented by bit shifting one sample three bits to the right and computing the difference between it and an adjacent sample.

Abstract: A light beam from a source (14) is chopped by a chopper (16) and split by a beam splitter (24) into two beams. The intensity of a first beam is changed by using, e.g., an electrooptic material (12) in accordance with a change in a signal to be detected, such as a voltage in an electronic device. The intensity of the first beam is detected by a first photodetector (22). The second beam is detected by a second photodetector (26) without its intensity being changed to provide a reference signal. At least one of the outputs of the first (22) and second (26) photodetectors are adjusted so that they are equal when no signal is applied to the light intensity changing means (12). The difference of the thus adjusted output signals is detected a narrow band detecting means (28) such as a lock-in amplifier (42C) in a narrow band at the chopping frequency to provide an output having a greater sensitivity.

Abstract: Injection-moulding machine, plastics processing, platen fixed, moving, injection unit, high-speed cylinders, pivot point, sliding shoe which can swivel, longitudinal axis, inclined, piston rod, vertical distance. The invention relates to an injection-moulding machine comprising an injection unit, a fixed platen and a platen which can be moved on sliding shoes by long-stroke hydraulic high-speed cylinders on a guide track of a base frame. When the mould is closed, the platens are able to be locked by means of tie bars mounted self-supportingly therein. The mould height can be set by a mould height adjusting device. The aim is to develop an inexpensive high-speed drive which is arranged in a space-saving manner and reduces the amount of wear occurring. The solution provides for the high-speed cylinder(s) to be arranged between the moving platen and the injection unit in such a way that the longitudinal axis is inclined by an acute angle in relation to the horizontal guide track and, at the moving-out end for the piston rod is mounted in the base frame in such a way that it can swivel about a pivot point. The end of the piston rod is jointedly connected to the sliding shoes at a pivot point, the vertical distance from the mass centre of the moving platen to the pivot point in the sliding shoe being less than the vertical distance to the pivot point of the high-speed cylinder. <IMAGE>
