  • Patent number: 5741963
    Abstract: To improve the accuracy of the automatic adjustment of a spark plug and the adjustment of the eccentricity of a multiple-electrode spark plug, a spark plug holder 2 for supporting and fixing a lower portion of the multiple-electrode spark plug 1 and a positioning device 3 for supporting and positioning an upper portion of the multiple-electrode spark plug 1 are provided to an adjustor for automatically regulating the gap and the eccentricity of the multiple-electrode spark plug having a center electrode and at least one ground electrode. A projector 4 projects light to the multiple-electrode spark plug 1 from above the positioning device 3. A CCD camera 5 produces images of the spark gap/eccentricity of the multiple-electrode spark plug 1. An image processor 6 executes image processing for inputting the images from the CCD camera 5 and determining the spark gap/eccentricity.

  • Patent number: 5021725
    Abstract: An arrangement for preventing inductive interference in an electric car having a power receiver for receiving DC power from a feeder line connected to a DC power supply, an inverter connected between the power receiver and a ground side terminal connected to a rail via a wheel for converting the DC power fed from the power supply into AC power, and a motor driven by the output of the inverter, the arrangement being adapted to prevent a high-frequency signal current transmitted from and/or to a signal station from being affected by inductive interference due to switching currents of the inverter flowing from switching elements of the inverter to a return line by way of a capacitance between a frame and a stator winding of the motor.

  • Patent number: 4757240
    Abstract: A main circuit of an electric vehicle using an induction motor is constituted by an invertor for producing three phase AC power having a variable frequency and a variable voltage and a three-phase induction motor supplied with the AC power by the invertor. The rotational speed of the induction motor is detected and a slip frequency signal is added (in power running) or subtracted (in regenerating running) to or from the rotational speed to control the output frequency of the invertor. On the other hand, the output voltage of the invertor is controlled to be in proportion to the output frequency thereof. The output voltage of the invertor is limited in accordance with notch positions of a master controller of the electric vehicle so as to be provided with a voltage notch stopping characteristic of the conventional electric vehicle.

  • Patent number: 4600048
    Abstract: A thin metal strip excellent in both shape and quality is produced by a continuous casting process which comprises the steps of jetting a molten metal through a nozzle onto the surface of a moving chill body maintained at a pertinent temperature range by irradiating a high density energy at a place positioned at the rear of the nozzle, and subjecting the molten metal to quenching so as to effect solidification.

  • Patent number: 4437907
    Abstract: Amorphous alloys have attractive properties which make possible their use as cores for transformers, these properties being a low watt loss, which is due to an inherently low magnetic anisotropy, and a high resistivity. However, one of the most serious disadvantages of amorphous alloys is the low thermal stability of the magnetic properties and the fact that their magnetic properties, such as saturation flux density (Bs), decrease at the temperature of the energized or excited core.In order to eliminate the disadvantages of the known amorphous alloys, the present invention proposes an amorphous alloy having a composition of Fe.sub.74-80 Si.sub.8-19 B.sub.6-13 C.sub.0-3.5. This alloy is specifically adapted so that it can be used as a transformer core which can be energized or excited at a high flux density.
