    摘要: A method for controlling and regulating the working cycles of a machine tool on a workpiece, including the steps of measuring the workpiece during the machining and programming the feed speed of the tool depending on another variable quantity, which foresees generating a signal responsive to the elastic strains suffered, during the machining, by the kinematic chain comprising the workpiece and the tool, as a consequence of the tool thrust. The signal is used for controlling the feed speed. An apparatus for controlling and regulating the working cycles of a machine tool including a measuring device for the measurement of the sizes of the workpiece being machined, a stepping motor, a digital counter, a digital analogue converter and adapter responsive to the position of the tool relative to a reference position, a differential amplifier, a program unit for programming the feed speed of the tool and a control unit for varying the feed speed. The stepping motor, digital counter, digital analogue converter and adapter responsive to the position of the tool and the measuring device are connected to the differential amplifier adapted to provide a signal responsive to the elastic strains suffered, during the machining, by the tool, workpiece and kinematic chain, due to the tool thrust. The output of the differential amplifier is connected to the program unit for varying the feed speed of the tool depending on the elastic strains.

    摘要: A method of transmitting signals from a base station towards user terminals in a cellular communication system. The method includes generating diversity signals, wherein at least one of the diversity signals is subjected to a selectively variable RF phase shift. Specifically, a set of radio link quality indicators is determined at the base station, wherein each radio link quality indicator is representative of the quality of the radio link between the base station and a respective one of the user terminals. The set of radio link quality indicators is used to generate an aggregated radio quality indicator, which in turn is used to selectively vary the variable RF phase shift. For example, the phase shift may be selected, which optimizes the aggregated radio quality indicator.

    摘要: An automatic safety syringe comprising a syringe body, hollow on the side and open at the front and rear; and a plunger sliding inside the syringe body with an injection stroke extending from a retracted syringe-filling position to a forward syringe-emptying position, the plunger being provided at the rear with a shaft that can be operated manually and brought out of the syring body through the rear end thereof. An injection needle integral with a needle carrier is egageable with the fore end of the syringe body. A hooking device is connected to the shaft of the plunger, to hook the needle carrier when the shaft is at the end of the injection stroke. An automatic device causes automatic retraction of the shaft of the plunger when the injection has been completed. a locking device is operatively connected to the shaft to block forward movement thereof when it is in the retracted position after intervention of the automatic device.

    摘要: An external heat sink is soldered to an internal heat sink incorporated into the bottom of a molded body of encapsulating resin for a package of an integrated power device. The power device is for surface mounting on a printed circuit board. The internal heat sink has at least a portion protruding from an outer surface of at least one face of the molded body. An external heat sink is mounted on the printed circuit board. The external heat sink has at least a surface abutting with a surface of the body, thus defining a separation gap between at least a surface of the protruding portion of the internal heat sink and an opposing surface of the external heat sink. This separation gap is filled with molten solder alloy during a normal soldering treatment of the printed circuit board.

    摘要: A radio resource scheduling method for scheduling radio resources used for communications in a radio communication system includes user equipment configured to communicate with transceiver stations on the radio resources. The transceiver stations are configured to exchange coordination messages concerning radio resources affected by intra-system interference. The radio resource scheduling method includes allocating to each user equipment served by a transceiver station a corresponding radio resource and a corresponding transmission power level to communicate with the serving transceiver station. Allocating is based on coordination messages exchanged by the serving transceiver station.
