    • A brushless motor drive circuit including at least one hall effect element and a drive transistor circuit adapted to produce a signal to energize at least two drive coils, which coils operate to drive the brushless motor. The amplitude of the signal applied to said drive coils is determined by the current supplied to the drive transistor circuit. A control circuit is provided for controlling said supplied current in response to the speed of the motor. The control circuit includes a single transistor coupled to said drive transistor circuit, the series connection of a constant voltage produced by a voltage limiting device and a voltage representative of motor speed being coupled to the base of the transistor to bias the control transistor to maintain a constant motor speed.

    • An image display system transmits and receives supplied data which can be converted by a virtual machine among plural processing devices which are connected via a transmission line, and creates and displays an image. At least two processing devices among the plural processing devices each includes an image display device. At least one of the image display devices includes a conversion device, in which a virtual machine is provided, that converts the supplied data into a data format in which an image can be displayed, a communication interface section that receives the supplied data from another processing device, and a storage device in which created images are stored and which can be accessed from another processing device via the communication interface section. Each of the at least one of the image display device and the other image display device reads some of the images from the storage device and display the images in a shared manner, the other image display device having the conversion device and the communication interface section.
