Abstract: The invention relates to an overcentre spring device for a motor-vehicle pedal mechanism with components pivotable relative to one another about a bearing pivot, in which a telescopic guide and connecting rod spring-loaded in the direction of extension by a helical compression spring surrounding it is supported loosely by each of its end pieces in abutments of the components pivotable relative to one another, the interacting abutments and end pieces each having mutually corresponding concave and convex sliding surfaces. According to the invention, at least one of the two abutment/end piece pairs is provided with outer, chamfered assembly run-in surfaces adjacent to its sliding surfaces, the said run-in surfaces being designed and matched to one another in such a way that the pressure spring device can be fitted into the foot lever mechanism without recourse to technical aids, solely by means of a force exerted on the connecting rod essentially transversely to the longitudinal extension of the connecting rod. <IMAGE>

Abstract: The invention relates to an arrangement and a method for removing printing ink from guide rollers (11) in a printing press. 
     As a paper web (2) moves along its normal path through the printing press while printing is suspended, a prin­ting-ink solvent (6), preferably a mineral-oil frac­tion, is sprayed onto the paper web, either upstream or downstream of a printing machine (1). The printing-ink deposits on the rollers (11) are dissolved by the sol­vent as the sprayed paper-web (2) passes over the roll­ers (11), and the dissolved printing ink is then wiped from the rollers with a non-sprayed part of the paper web (2). 
     In accordance with one preferred embodiment, the sol­vent (6) is sprayed onto the paper web (2) in one or more sinusoidal paths and the guide rollers (11) are subsequently braked, preferably to a complete stop and preferably pulse-wise when the sprayed part of the web and the wiping part of the web (2) passes over the rollers. The duration of the pulses is preferably vari­able and adapted to the cleaning effect desired.

Abstract: In a semiconductor device fabrication process, a so-called alignment mark or position-alignment mark (1, 11, 21, 22), and a laser trimmer are used. The position-alignment mark makes a considerable difference in amount between a vertically reflected laser beam light from the position-alignment mark and that from the background thereof to strengthen a contrast between the position-alignment mark and the background surrounding the mark, so that a signal-to-noise ratio (SN ratio) is considerably improved to enable a precise position alignment to be performed in the semiconductor device fabrication process. The position-alignment mark comprises: a position-detecting target (2) having high reflectance; and a pair of low-reflectance regions (3) which sandwich the position-detecting target (2) therebetween.

Abstract: A tuning system includes a microcomputer-based synchronization signal detector which does not require the use of a hardware timer/counter. The microcomputer (117) samples the output signal of a sync separator (111) coupled to an ordinary input/output port (143) during a number of different evaluation intervals to determine if respective characteristics of a valid sync signal occur. During one evaluation interval, a test is performed to determine if a "high" level is present for a time duration less than a given time duration (e.g., 10µS) corresponding to the maximum duration of horizontal sync pulses. During another evaluation interval, a test is performed to determine if a "low" level is present for a time duration greater than another given time duration (e.g., 40µS) corresponding to the minimum separation between horizontal sync pulses. The sampling intervals and evaluation intervals are established by the time required to execute instruction cycles.

Abstract: In known spectrophometers, a single light source is used to illuminate both a sample and a reference. A single detector is used to detect the light at both the sample and the reference. A chopper wheel having aperture portions is used to allow the light to pass through a selected filter in the apertures. However, in such devices, the beams from the sample and the reference arrive at the detector at the same time and movable shutters need to be employed. Described herein is a spectrophotometer (10) comprising a single light source (12), a single detector (14), optics (30, 36, 340, 42, 44, 46, 48, 50, 52, 54, 56, 58, 90, 92, 100) for dually and alternatively reading a sample (94) and a reference (96), and which employs only one moving part. That moving part is a chopper (42) containing multiple pass-through apertures (60a, 60b, 60c, 60d, 60e, 60f), each filled with a unique bandpass filter to select wavelengths to specifically illuminate the sample (94) or reference (96). To inform the spectrophotometer (10) whether and when it is reading the sample (94) or the reference (96), energy relay means (70a, 70b, 70c, 70d, 70e, 70f, 70g, 70h, 70i, 70j, 70k, 70l) are provided between an energy emitter (80) and an energy detector (82) in an amount of at least twice the number of the pass-through apertures (60a, 60b, 60c, 60d, 60e, 60f).

Abstract: In a connector, a terminal lock member has openings in correspondence to terminal accommodating chambers formed in a connector housing. Of the vertical plates forming the terminal lock member, two are suitably selected. Each of the vertical plates thus selected has a first locking protrusion on one end face thereof, and a flexible arm formed by cutting a slit therein in such a manner that the flexible arm has a second locking protrusion on the other end fact. On the other hand, the connector housing has first and second engaging portions and in correspondence to the first and second locking protrusions. When the terminal lock member is inserted into the housing through the cavity to a temporary locking position where the openings align with the terminal accommodating chambers, the first locking protrusions are engaged with the first engaging portions, so that the terminal lock member is temporarily locked there. When the terminal lock member is further inserted into the housing from the temporary locking position to a real locking position where the terminal locking portions are engaged with terminals to prevent the latter from coming off backwardly, the second locking protrusions are engaged with the second engaging portions, whereby the terminal lock member is positively locked there.
