摘要： A device for deactivating a magnetomechanical EAS marker includes two coils and an energizing circuit for alternately driving the coils. One coil is driven for one cycle of an alternating power signal, and then the other coil is driven for one cycle, and this sequence is repeated. The driving signal is switched from one coil to the other at a point in time which corresponds to a zero crossing of the current level of the driving signal.

摘要： A digital controller in a photographic camera comprises a microcomputer and one or more digital computer controlled input and output transducers such as scene light measuring means, subject distance measuring means, and means for controlling aperture size, shutter time, or focus adjustment. The microcomputer receives inputs from the input transducers and controls the output transducers in response thereto according to a control program stored in a computer memory. The controller includes a programable memory containing custom control constants to custom tailor the operating program for the specific apparatus in which it resides. According to a preferred embodiment of the invention, a high precision photographic camera is produced by first making the photographic camera, then operating the camera under known operating conditions using a nominal control program. The responces of the output transducers under the known operating conditions are measured and custom tailored control constants are generated for the camera. The custom tailored control constants are then programed into the programable memory to bring the operation of the camera into conformity with desired parameters to complete the manufacture of the camera.

摘要： The present invention provides for magnetic and magneto-optic recording media, transducers and data storage devices constructed therefrom that have highly oriented films having long range order in the crystal structure of the film. The recording medium includes a magnetic recording layer comprised of Co-based material, such as Co or one or more Co alloys having a (10{overscore (1)}0) crystal texture, a substrate, a first underlayer having a fcc structure and a (110) crystal texture disposed between the substrate and the magnetic recording layer. A second underlayer having a bcc structure and a (112) crystal texture is also disposed between the magnetic recording layer and the first underlayer. In particular, if a (110) Si single crystal substrate is non-oxidized certain metals having fcc structures, such as Ag, Cu, Al, and Au and fcc derivative structures, such L10 and L12 structures, can be epitaxially grown on the Si surface. While the one unit cell to one unit cell lattice match between fcc Ag and A4 (diamond) Si is quite poor, multiples of the Ag unit cell distance fit very well on the Si surface. The long range order of the Si surface induces the epitaxial growth of the Ag fcc structure. Upon this fcc structure, a bcc structure, such as Cr, or a bcc derivative, such as B2, DO3 and/or L21 can be epitaxially grown.

摘要： A flow modulation valve has a slidably translating hollow armature with at least one energizable coil wound around and fixably attached to the hollow armature. The energizable coil or coils are influenced by at least one permanent magnet surrounding the hollow armature and supported by an outer casing. Lorentz forces on the energizable coils which are translated to the hollow armature, increase or decrease the flow area to provide flow throttling action. The extent of hollow armature translation depends on the value of current supplied and the direction of translation depends on the direction of current flow. The compact nature of the flow modulation valve combined with the high forces afforded by the actuator design provide a flow modulation valve which is highly responsive to high-rate input control signals.

摘要： A rangefinder device includes means for projecting a beam of light to illuminate a spot on an object in a scene. A linear image sensor views the scene and produces a series of photosignals representing the brightness of the scene. Signal processing electronics responsive to the photosignals from the linear image sensor detect the location of the illuminated spot in the scene and produce a distance signal representing the distance to the object. The signal processing electronics include:a counter that is advanced each time a photosignal is received from the image sensor;a latch connected to the counter and responsive to a control signal for temporarily storing the current count of the counter; anda peak detector responsive to the photosignals for producing an output signal each time a new greater photosignal is received.The output signal of the peak detector is supplied to the latch as the control signal. After the series of photosignals has been produced by the image sensor, the count remaining in the latch represents the location of the illuminated spot in the scene. The peak detector includes means for setting a threshold peak value below which no peak is detected.
