    摘要: In picture-reproducing equipment with higher scanning frequencies (e.g., flicker-free television, visual display unit), the generation of the horizontal-deflection current is separated in frequency from the generation of the operating voltages by supplying the horizontal-deflection circuit from a DC voltage source which is part of the voltage power supply providing the operating voltages. The supply circuit is preferably connected to the grounded deflection capacitor. This makes it possible to influence the picture geometry in a simple manner, particularly to perform horizontal pincushion correction.

    摘要: The spatial position of the core of an optical waveguide (1) can be observed exactly in that the optical waveguide is irradiated, in two mutually perpendicular directions, with parallel light, which thereafter passes through each time one rod lens (31, 32) and into a deflecting optical system (8, 9, 10). With the aid of this deflecting optical system it is possible to produce two side-by-side images of the optical waveguide and its core. With the aid of such an arrangement the cores of two optical waveguides to be joined, can be optically aligned with respect to each other in a simple way.

    摘要: A flexible hinge device comprises a laminar silicon body having a groove portion etched away to define a thin flexible strip joining two rigid end portions. The silicon forming the hinge is usually of a single crystal structure. Break-off supports may be provided to support the structure prior to use.

    摘要: In a push-button switch, the switch element is a cantilever (2) of thin silicon strain gauge material with a small magnet (1), e.g. of samarium cobalt alloy at its free end. Adjacent to the free end there is an annular magnet (3), e.g. of plastics material impregnated with samarium cobalt alloy, on the push rod (4) of the switch. The annular magnet (3) is so poled that movement of the rod (4) causes, due to magnetic forces, the deflection of the silicon strain gauge to give an electrical output.The return force, plus collapse action, is provided by a soft iron collar (5) on the switch structure.

    摘要: A transmission chip for a telephone subscriber's instrument can be used in a variety of modes, some of which involve use with other chips. Depending on which mode is in force, different amplifiers are used. Thus for plain ordinary telephone (POT) service, amplifiers 30,35 and 43 are used, for loudspeaking mode amplifiers 30, 35 and 43 are used, for handsfree use amplifiers 35, 43 and 46 are used, while for VF "dialling" amplifier 46 is used. To save power, the control block (42) detects the mode in which the set is operating and, via a control bus, operates electronic switches to disable the amplifiers not needed.

    摘要: The invention relates to a method of transferring information between microcomputers in a decentralized process control system, particularly for telephone systems. To prevent contention for possession of the information transfer bus without the need for central equipment, a simple bus system consisting of a multiwire data bus and two single-wire control buses is proposed. Bus mastership is passed on after transmission, with the address of the next transmitter being determined by each microcomputer itself and forming part of each message. Bus mastership is determined by communication of the previous transmitter and by calculations performed by the microcomputer itself.
