Abstract: Integrated, juxtaposed head units of a magnetic head have transducing gaps directly adjacent a central plane transverse to the longitudinal direction of relative movement of a magnetic recording medium, adjacent transducing gaps being to opposite sides of the central plane. Head units adjoin each other so that a recording channel density of 100% is achieved. In one embodiment a common electrical conductor passes through a plurality of head units to one side of the central plane, and electrical connection tracks extending from a portion of the conductor form inductive transducing elements.

Abstract: A threaded insert is designed to snap into a standard bone plate hole. The insert has an upper section divided into sectors by slots, a lower section having deflectable tabs with external projections, and a central threaded hole. When a standard bone screw is tightened in the insert, the insert rigidly fixes the screw to the plate by collapsing the threads of the insert onto the threads of the screw, and by expanding the sectors of the upper section to clamp the bone plate.

Abstract: The invention relates to an electromotor comprising a stator part and a rotor part, which parts form an oil-containing spiral groove bearing system. Surface areas of said parts are provided with a so-called oil barrier in order to prevent the oil from creeping from the bearing system to the environment. According to the present invention, said oil barrier comprises a monolayer of perfluorocarboxylic acid anions, especially those having a chain length of 10-20 C-atoms and/or perfluoroalkylthiol anions. Oil barriers of this type can be easily provided on the rotor part and stator part by means of dipping. These oil barriers have a very small thickness and can very suitably be used to prevent oil creepage.

Abstract: A peak detector that is particularly suitable for measuring the peak value of an RSSI-signal in a digital communication device. The peak detector includes a peak value storage capacitor which is charged by a high current or by a low current. When the RSSI-signal is greater than the output voltage of the peak detector, the storage capacitor is charged with the low current. When the RSSI-signal is substantially greater than the output voltage of the peak detector, the storage capacitor is charged with the high current. Herewith, it is achieved that the peak value of the RSSI-signal is determined quickly, without any overshoot, i.e. the peak value is determined accurately.

Abstract: A circuit having a Cartesian amplifier is disclosed. The Cartesian amplifier includes a re-combining stage which re-combines an input signal from a signal source with a correction signal to output a result signal. A first mixer mixes the result signal with a first oscillating signal from a local oscillator. A power amplifier amplifies the mixed signal and a coupler couples part of the amplified signal to form an outcoupling signal. A feedback path has a second mixer for forming the correction signal by mixing the outcoupling signal with a second oscillating signal from the local oscillator. An envelope curve detector detects the envelope of the amplified signal to produce an envelope signal, and a phase adjustor adjusts the phase of the first or second oscillating signal. A control circuit is provided to control the phase errors in a phase locked loop of the Cartesian amplifier and to minimized the envelope signal.

Abstract: A ring binder (10) stores hole (H) punched sheets of paper (P). A mechanism (16) is a bolt action mechanism which positively locks binder rings (18) which hold paper in its stored position. Each binder ring includes a fixed section (20) and a movable section (22). All of the movable binder ring sections are commonly mounted on a bolt (36) and move in unison with the bolt. A manually operable lever (38) is secured to one end of the bolt. When the lever is moved in one direction, the bolt is rotated so to move the movable sections of the binder rings away from the fixed sections and open the binder. Operation of the lever in the opposite direction brings the movable sections back into contact with the fixed sections to close the binder.
