    摘要: In a control system for a power transmission and distribution system, a plurality of distributed power supplying and receiving units each including a control unit are provided and connected along a power distribution line. The power supplying and receiving unit function to generate active and reactive powers of fundamental and higher harmonic waves to supply and receive the same to and from the power distribution line. A first central control unit controls the power distribution line and is designed to store information relating to the configuration of the power distribution line, to collect information with regard to instant open and close conditions of respective disconnecting switches connected for sectioning the power distribution line, and with regard to current electrical quantities on the power distribution line. Individual control command signals specific to the respective power supplying and receiving units are produced based on the stored and collected information and the respective power supplying and receiving units are controlled so that a desired target condition of the power distribution line is achieved autonomously within the power distribution line through an optimum cooperation control of the units.

    摘要: A composite longitudinal vibration mechanical filter for delivering out a supplied high-frequency signal in a predetermined frequency range includes a plurality of vibratable bodies including input and output longitudinal vibratable tuning bars with piezoelectric members superposed thereon, coupling elements by which the longitudinally vibratable tuning bars are coupled to each other, supporting elements projecting respectively from the input and output longitudinally vibratable tuning bars, and a holder to which the supporting elements are attached. At least one resonant frequency adjusting finger is disposed on at least one of the vibrational bodies. Grooves are defined in the longitudinally vibratable tuning bars at the same time that they are fabricated. The grooves extend in the direction in which the longitudinally vibratable tuning bars are longitudinally vibratable, and are shorter than the length of the longitudinally vibratable tuning bars. Through holes may instead be defined in the longitudinally vibratable tuning bars, the through holes having an opening size smaller than the wavelength of the longitudinal vibration of the longitudinally vibratable tuning bars. Piezoelectric members are fixedly superposed on the input and output longitudinally vibratable tuning bars in sandwiching relation thereto.

    摘要: There is disclosed a disk loading device capable of transferring a disk without damaging a face of the disk. The disk loading device includes a roller movement mechanism for moving a roller toward and away from a path of transfer of the disk, and a roller drive mechanism for rotating the roller. The roller is brought by the roller movement mechanism into contact with an outer peripheral surface of the inserted disk, so that the disk is transferred by the rotational drive force of the rotating roller in a predetermined direction. For discharging the disk, the outer peripheral surface of the disk is urged by an eject mechanism operatively connected to the roller drive mechanism, so that the disk is ejected.

    摘要: An apparatus for effecting a fine movement of an object for making use of impact produced by a piezoelectric/electrostrictive element having a moving member, a piezoelectric/electrostrictive element attached to said moving member, means for driving the piezoelectric/electrostrictive element, and an inertia member operative in response to the driving of the piezoelectric/electrostrictive element so as to impart an impact to the moving member. As an electric field is applied to the piezoelectric/electrostrictive element, a strain is caused by a stress which acts to expand or contract the piezoelectric/electrostrictive element to a length determined by the level of the electric field. By making use of this phenomenon, impact is produced by the inertia member which operates in response to the stress, thereby effecting a step-like fine movement of the moving member. Thus, the inertia member is impactingly driven by elongation or contraction of the piezoelectric/electrostrictive element so that a reactional force overcomes the friction acting between the moving member and a base so as to realize a fine movement of the moving member.

    摘要: A PLL synthesizer for a multi-channel civil band transceiver uses a D-flip-flop between a voltage controlled oscillator and a programmable divider which are parts of the loop. A reference signal is divided in a first divider to form a signal representing the frequency difference between adjacent transceiver channels which is applied to a phase comparator in the loop and the reference signal is frequency divided in a second divider to obtain a signal applied to the clock input of the D-flip-flop.
