    摘要: A semiconductor integrated circuit receiving at its input pin the terminal voltage of a capacitor which is connected to a power source through a resistor so as to detect the level of the power voltage. The circuit is provided with a level shift circuit which shifts the incoming power voltage level by a predetermined value so that a reset signal is produced by detecting the output of the level shift circuit falling below the threshold level of a logic circuit.

    摘要: A magnetic bubble memory device is provided with a plurality of memory modules each having at least one magnetic bubble chip. Each module generates a clock for determining the timing to drive the magnetic bubble chip and controls the operation of the magnetic bubble chip. The addresses of a main memory are cyclically allocated to the memory modules in a given unit, so that data transmission can be performed between the memory modules operated asynchronously with each other and the main memory allocated thereto.

    摘要: The present invention provides an improved method and apparatus for driving a magnetic bubble device, in which a d-c voltage supply and drive coils are connected to a bridge circuit consisting of four bi-directional switches, and alternating currents with steps (such as currents consisting of triangular waves or trapezoidal waves) are produced in the drive coils by suitably controlling the turn on or off of the bi-directional switches. As a result, the d-c level in the alternating current is not shifted by the variation in width of pulses which control the opening and closing of the bi-directional switches, and the magnetic bubble device is provided with a greatly improved operation margin.

    摘要: An image display apparatus includes a light-source driving circuit that drives a light source to cyclically change brightness. A control unit controls a pixel to turn on and off over a plurality of subfields in a field so that transmittance or reflectance in the pixel over the plurality of subfields in the field corresponds to a gray level specified for the pixel. The control unit also arranges the plurality of subfields such that two or more gray-level defining subfields maintain a predetermined relationship with respect to the cyclical change in brightness of the light source caused by drive of a light-source driving circuit.
