Patent EP-0034808-A2 (EP)
Inventor: YANASE TAKAO
IPC: H02P27/16
Filed: 1981-02-19
Abstract: The invention relates to a circuit arrangement for the compensation of a phase difference between the actual values of multi-phase load currents (iR, iS, iT) and required currents (iR<*>, iS<*>, iT<*>) in a power converter. In this arrangement, the multi-phase currents (iR<*>, iS<*>, iT<*>) are converted into two-phase currents I cos omega t, I sin  omega t in a coordinate converter (80). A vector rotator (70), connected downstream, shifts the phase of the two-phase currents by the phase difference k omega . Subsequently, in a coordinate converter (60) connected downstream, the two-phase currents I cos ( omega t + k omega ), I sin ( omega t + k omega ) are converted, with a shifted phase, into multi-phase currents ((iR<*>), (iS<*>), (iT<*>)) for driving the power converter (2) such that the phase shift between the actual values (iR, iS, iT) of the multi-phase currents and the required currents (iR<*>, iS<*>, iT<*>) is compensated for. By means of this compensation, the phase between a required current and an actual value of the load current in a power converter can be matched to one another so that the required currents can be used for computing circuits rather than the actual currents, which are encumbered with interference. <IMAGE>

Abstract: In a method of molding a large plastic structure which includes applying a vacuum to draw the molds together, injecting resin into the space between the molds while the vacuum is applied, maintaining the vacuum at least until the resin gels, removing the vacuum, allowing the molded structure to harden, removing the male mold and then removing the molded structure, molding is carried out on a moving production line without danger of disturbing the resin while gelling by disposing the molds on bogies and moving the bogies onto motor driven glide rollers at the point where the resin is injected, and the bogies transported on the glide roller drive until initial gelling has taken place. 
     In order to maintain a vacuum at a plurality of molds on an assembly line, each mold has its own vacuum unit operating with compressed air and a plurality of molds are interconnected to supply compressed air in series to each of the molds.

Abstract: A circuit for performing sustaining and pulsing operations for an AC plasma panel is disclosed, wherein two MOSFET transistors are used to alternatively, selectively provide a two level output signal. The circuit requires only a single logic input, thus preventing both transistors from conducting simultaneously, and features full slew rate control of the output. The drive circuitry is improved so that the waveforms applied to the panel electrodes to perform the sustain, write, erase, and bulk-erase functions are simplified to comprise a sequential series of rectangular waves, and only one high voltage power supply is required. High voltage is supplied to the driver chips only when they are to perform a write or erase function, thus greatly reducing the amount of power which must be dissipated in the driver chips.

Abstract: A low resistance ohmic contact to a layer (6) of n-type GaAs is made by first vapour depositing layers (8, 10, 12) of Ni, Au and Ge on the GaAs, followed by a layer (14) of SiO z . This structure is heated to a temperature of 450°C within ten seconds and the structure is maintained at that temperature for 30 seconds to form an alloy ohmic contact. The structure is then rapidly cooled by applying a heat sink (20) to the back surface (5) of the substrate (2) supporting the GaAs layer (6). The technique may be used to form ohmic contacts to other n-type Group III-V semiconductors. Ohmic contacts formed using this method exhibit a very fine, high density, uniform granular structure.

Abstract: In an automatic recording instrument having a thermal recording-pen to record on a heat sensitive recording-paper, an operational amplifier output supplies the heating current to the thermal pen through a resistor. A non-linear transfer element receives the output voltage of the amplifier and delivers a voltage having a predetermined non-linear relation to its input. The voltage difference between the output of the non-linear transfer element and the junction point of the thermal pen to the resistor is feedback connected to the input of the amplifier. When the relative velocity between the pen and the paper is increased, the input voltage of the amplifier is increased to increase the output voltage, and when the output voltage is increased, the resistance of the thermal pen is increased, to balance to the output of the non-linear transfer element for reducing the input to the amplifier. This means that the heated temperature of the thermal pen is raised when the pen moves faster on the paper and a constant thickness of the recording is maintained in a wide range of the relative velocity between the pen and the paper.

Abstract: n a repeater station for use in a repeater station to repeat a sequence of downward time slots and a succession of upward time slots, a detector (40) detects a synchronizing signal included in a particular one of the downward time slots. A timing circuit (41) produces a first timing signal when a first predetermined duration lapses after detection of the synchronizing signal. The first predetermined duration is preferably predictively determined in consideration of a reception time instant of a particular one of the upward time slots that corresponds to the particular downward time slot. Signals included in each upward time slot are memorized in a memory section (60) with reference to the first timing signal. The timing circuit further produces a second timing signal after the first timing signal to transmit the memorized signals to an upward station. The second timing signal is produced in consideration of a deviation with the upward time slots reach the upward station.
