摘要： A transformer with an electrostatic shield body between its primary and secondary windings, one end of the shield body being connected to a zero potential point of the primary side from the AC standpoint. This reduces the capacity coupling between the primary and secondary windings. This transformer is particularly useful with an inverter.The transformer may include primary and secondary windings, each having a pair of terminals, and a magnetic core provided in connection with the primary and secondary windings magnetically. First and second static shield bodies may be provided at each side of the primary and secondary windings and therebetween, and these first and second static shield bodies are electrically connected to one terminal of the primary and secondary windings, respectively, so as to reduce the capacitance therebetween.

摘要： A transistor inverter includes at least a pair of switching transistors, a transformer with primary and secondary windings, a DC voltage source with a pair of output terminals and a voltage reference terminal, and a rectifying circuit connected to the secondary winding of the transformer. A collector electrode of one of the switching transistors is insulated from a chassis by an insulation means comprising a first insulating layer, a conductive layer such as a heat sink and a second insulating layer. The conductive layer is electrically connected to the voltage reference terminal of the DC voltage source so as not to produce an undesirable radiation through the chassis.

摘要： A surge current protection circuit includes an input terminal supplied with a rectified alternating voltage, an output terminal to be connected to a load, and a semiconductor controlled rectifier having its anode and cathode electrodes connected in series between the input and output terminals. The collector and emitter electrodes of a control transistor are connected between the gate and cathode electrodes of the rectifier. The base-emitter voltage is supplied with any sharp transients, and the transistor becomes conductive before the rectifier if the transients are sharp enough and of high enough amplitude. Conduction of the transistor prevents the semiconductor controlled rectifier from conducting surge currents and protects circuits connected in series with the rectifier.

摘要： A method of manufacturing a tubular carbon molecule capable of regularly aligning a carbon nanotube with a finer spacing is provided. A catalyst is arranged on a material substrate (10) made of a semiconductor such as silicon (Si) and including iron (Fe) as a catalyst through the use of melting according to a modulated heat distribution (11). The heat distribution (11) is formed, for example, through diffracting an energy beam (12) by a diffraction grating (13). As a method of arranging the catalyst, for example, iron may be deposited in a planar shape or a projection shape in a position corresponding to the heat distribution (11), or the deposited iron may be used as a master to be transferred to another substrate. A carbon nanotube is grown through the use of the arranged catalyst. The grown carbon nanotube can be used as a recording apparatus, a field electron emission device, an FED or the like.

摘要： An optical recording medium on which a data signal is formed comprises an area A of recording tracks for recording a data signal between pairs of grooves Gr and a d.c. offset cancel area B for canceling d.c. offset by the push-pull system, which serves as a predetermined area. In the d.c. offset cancel area B, no grove Gr is formed, and grooves are formed at the recording track center positions Tc. The groove at the recording track center position Tc is caused to have the same width and depth as those of the groove Gr. In carrying out recording/reproduction of a data signal by using this optical recording medium, a return light from the optical recording medium is detected by a bisected detector. A difference signal between outputs from the detector is determined by an amplifier. In accordance with an output signal of a sample-hold signal supply unit, first and second sample-hold units respectively hold signals having output phases different from each other by 180 degrees. An adder adds these signals to take out only a d.c. fluctuation component to eliminate the d.c. fluctuation component superimposed on a tracking error signal at a d.c. offset eliminating unit.

摘要： An optical pickup is controlled to move to a target track on an optical information storage disc based on target value information representing the sum of speed information indicative of a speed at which the optical pickup is to move, and distance information indicative of a distance which the optical pickup has moved toward the target track. A first subtractor produces a differential signal indicative of the difference between the target value information and remaining distance information which represents a remaining distance that the optical pickup is to move. The differential signal is supplied to a second subtractor which determines the difference between the differential signal and actual speed information indicating an actual speed at which the optical pick is moving. The second subtractor produces a differential signal which is supplied to an actuator to move the optical head.
