Filed: 1988-07-28
Abstract: In a method for controlling a lens (24) of an image forming apparatus (1), the lens (24) is moved at a high speed from a present position till passing a home position, and thereafter the lens (24) is moved at a low speed in the reverse direction to stop at the home position. Waste of time can be decreased and rapid control of the lens (24) can be achieved by high speed movement of the lens (24) to a position near the home position, and the lens (24) can be precisely stopped at the home position by low speed movement of the lens before stopping.

Abstract: Compositions containing acrylamide functional polyorganosiloxanes, methacrylate functional and dialkoxy functional terminated polydiorganosiloxanes, a photo-­initiator, and an organic titanate provide a dual curing characteristics. The compositions cure by exposure to ultraviolet radiation and also cure by exposure to moisture, such as atmospheric moisture. The moisture cure characteristic provides these compositions with the capability to cure in the shadows where the ultraviolet radiation does not reach. Some of these compositions are useful as conformal coating for printed wire boards.

Abstract: A method, which can be implemented with little expenditure, for shifting the phase of a signal (S) in dependence on a control signal (p) specifying the phase shift proceeds in such a manner that two orthogonal cartesian signal components (x,y) are allocated to the phase in each case represented by the control signal, that the signal to be shifted in accordance with this phase is split into two signal portions (S1, S2) which are phase-shifted by 90 DEG  with respect to one another, and one of these two signal portions (S1, S2) is weighted proportional to one of the two orthogonal signal components (x, y) and the other signal portion is weighted proportional to the other signal component and that the signal portions thus weighted are subsequently combined again to form one output signal (a). <IMAGE>

Abstract: A contactless switch comprising a moveable body assembly (18) including a plunger (5) and a lens carrier (16) received in a casing (1) in an axially slidable manner between a light emitting element (9) and a light receiving element (10) which are also disposed along and on the axial line of the casing (1). Thus, the radial dimension of the switch can be reduced, and a compact design is made possible. Additionally, the actuating stroke of the moveable body assembly (18) can be made large without increasing the dimensions of the switch. In particular, since a switch output can be produced from a signal processing circuit when the amount of the light received by the light receiving element (10) has reached a certain predetermined level, the point of activation of the switch can be accurately defined by adjusting a reference level for the level of the light received by the light receiving element (10), and this adjustment can be easily carried out.

Zu Beginn jedes Ueberwachungsvorgangs werden für die einzelnen Sollwerte generalisierte Startgrössen verwendet, welche während des Ablaufs der Ueberwachung in Absolutwerte umgewandelt werden. Diese werden ständig aktualisiert und bilden die Kerndaten für einen automatischen Schlussfolgerungsprozess. Dadurch wird die Arbeitsweise des Systems, welches insbesondere in Spulereien zur Ueberwachung von Spulautomaten eingesetzt werden kann, automatisiert und objektiviert, und die Auswertung der Messergebnisse wird von der Interpretation durch das Bedienungspersonal unabhängig.

Abstract: A direction finding, motion-sensitive transducer, such as a hydrophone, includes an inertial mass (20) and a mounting base (21). A resilient means (24) interconnects the inertial mass with the mounting base. The inertial mass (20) extends along a symmetry axis when at rest in a non-accelerated condition, and the resilient means is adapted to permit the inertial mass (20) to wobble relative to the mounting base (21) in radial directions relative to the symmetry axis in response to and in accordance with the direction of components of acceleration of the mounting base which are transverse to the symmetry axis. A plurality of stress-­sensitive sensing elements (28-31) are arranged to respond to the wobbling motion of the inertial mass (20) relative to the mounting base (21), the sensing elements being located so as to define multiple directional channels which are adapted to produce outputs dependent on the directions of said acceleration components. The inertial mass (20), the resilient means (24) and the sensing elements (28-31) together define resonant systems. Damping means (40-41) common to the inertial mass, the resilient means, the sensing elements and the multiple directional channels defined by the latter are provided for controlling the resonance of the systems.

Abstract: 64 regions are set on an image sensed picture of a video camera, where evaluating values r ij , b ij  and y ij  are obtained by averaging color difference signals R-Y and B-Y and luminance signal Y obtained from an image sensing signal for over 1 field period by each region. When determination is made that the difference in the evaluating values between two continuing regions do not exceed a predetermined value according to the obtained evaluating values, that is, when determination is made that continuing regions have the same color, the weighing amount of the color evaluating values of a corresponding region is reduced in producing gain control signals regarding the color difference signals. As a result, the effect of objects of the same color towards white balance adjustment is reduced.
