    摘要: A method and apparatus for improving the sharpness of a video picture displayed on the screen of a cathode ray tube. At least one electron beam scans the screen in line-scanning and vertical directions, respectively, the electron beam having its intensity modulated in accordance with a video signal. The scanning velocity of the electron beam is modulated in the line-scanning direction in accordance with transitions of the video signal which correspond to transitions between high and low brightness levels of the displayed video picture. Each electron beam is shaped to have a substantially oval shape whose longer axis is disposed in the line-scanning direction and whose shorter axis is disposed in the vertical direction, whereby the oval-shaped beam impinges upon the display screen and the sharpness of the displayed video picture in the vertical direction is improved.

    摘要: In a circuit for controlling the current flow through a coil, such as the horizontal deflection coil of a television receiver, a first switching device including, for example, a first switching transistor and a first damper diode is connected in parallel with a first resonant circuit including a first capacitor and a first coil, which is the coil through which the current flow is to be controlled. A second switching device including for example, a second switching transistor and a second damper diode is connected in parallel with a second resonant circuit including a second capacitor and a second coil. First and second charging capacitors are connected in series with the first and second coils, respectively, and the power is supplied to the first and second resonant circuits for example through a third coil. Switching signals of the same frequency, for example, the horizontal frequency of a video signal, are applied to the first and second switching transistors with the phase difference between such signals being controlled to vary the relative voltages across the first and second charging capacitors and hence "to control" the current flowing through the first coil. The phase difference between the switching signals can be varied by a parabolic correcting signal having the vertical frequency of a video signal to cause the current flow through the horizontal deflection coil to correct for the side pin-cushion distortion of the raster of a cathode ray tube. In another embodiment of the invention, the phase difference between the switching signals can be modulated by a sawtooth wave signal having the vertical frequency so that the voltage across the first or second charging capacitor varies in a sawtooth manner at the vertical frequency and so that if a vertical deflection coil is connected across the first or second charging capacitor a sawtooth shaped current flow will take place through it, causing proper vertical deflection.

    摘要: On a single chip are formed a plurality of magnetoresistance effect elements provided with pinned layers having fixed magnetization axes in the directions that cross each other. On a substrate 10 are formed magnetic layers that will become two magnetic tunnel effect elements 11, 21 as magnetoresistance effect elements. Magnetic-field-applying magnetic layers made of NiCo are formed to sandwich the magnetic layers in plan view. A magnetic field is applied to the magnetic-field-applying magnetic layers. The magnetic field is removed after the magnetic-field-applying magnetic layers are magnetized in the direction shown by arrow A. As a result of this, by the residual magnetization of the magnetic-field-applying magnetic layers, magnetic fields in the directions shown by arrows B are applied to the magnetic layers that will become magnetic tunnel effect elements 11, 21, whereby the magnetization of the pinned layers of the magnetic layers that will become magnetic tunnel effect elements 11, 21 is pinned in the directions shown by arrows B.
