    摘要： A differential amplifier includes an input differential pair constituted by differential pair transistors whose common emitter is current-biased by a negative voltage source through a constant current source. An active load is formed by interconnecting through resistors input and output of a first and second current mirror circuit whose emitters serve as positive voltage sources. A collector output of each of the input differential pair is connected to each of the outputs of the first and second current mirror circuits. An output current amplifying stage comprises three emitter-grounded current amplifying stages whose emitters serve as positive voltage sources. The first current amplifying stage includes a capacity provided between the base and collector thereof and connected to one of current mirror outputs of the active load at the base thereof. The second and third current amplifying stages are connected to the other current mirror output of the active load at a common base. One of collector outputs thereof is connected to a negative voltage source through a resistor with a capacity provided between the base and collector. The other collector output is connected to the input of a third current mirror circuit whose emitters serve as negative voltage sources.

    摘要： In each odd-numbered frame, a game image generated by a three-dimensional image processing unit 31 is supplied to a first LCD 11, and then a game image identical to the generated game image is stored in a first VRAM 21a. Also, a two-dimensional image processing unit 37 supplies the game image stored in the immediately-preceding even-numbered frame in a second VRAM 21b to a second LCD 12. On the other hand, in each even-numbered frame, a game image generated by the three-dimensional image processing unit 31 is supplied to the first LCD 12, and then a game image identical to the generated game image is stored in the second VRAM 21b. Also, the two-dimensional image processing unit 37 supplies the game image stored in the immediately-preceding odd-numbered frame in the first VRAM 21a to the first LCD 11. With this, in a portable game machine including two display units, different three-dimensional game images can be simultaneously displayed by a single three-dimensional image processing unit on the two display units without flicker on the display screens.

    摘要： A recording apparatus includes a feed roller which feeds a paper sheet, a feed motor which drives the feed roller, and a loss-of-synchronism detecting unit which detects loss of synchronism of the feed motor. When loss of synchronism of the feed motor is detected by the loss-of-synchronism detecting unit, the rotational speed of the feed motor is reduced stepwise. Accordingly, it is not necessary to provide a high operational margin in the motor, and a recording apparatus, in which the motor and power supply costs are reduced, can be provided.
