Abstract: PURPOSE:To obtain the device which has high-speed scanning functions over a wide range by fixing an imaging means consisting of an objective lens to the tip of a mechanical oscillator such as tuning fork or cantilever and optically detecting the scanning position by a mirror fixed to the tip of the oscillator as well as a Michelson interferometer. CONSTITUTION:The objective lens 25 for imaging, a reflecting prism 26, and a retroprism 27 for measuring displacement are mounted to the tip 24 of the tuning fork 23. The objective lens 25 and reflecting prism 26 at the tip of the tuning fork move back and forth along the optical axis 34 of a luminous flux when the tuning fork 23 is excited by a driving coil 35. An object 33 is displaced in such position where the surface thereof is paralleled with the oscillating direction at the tip of the tuning fork 24. As a result, the focus 36 of the objective lens 25 scans the surface of the object 33. The retroprism 27 is provided to the side face at the tip of the tuning fork 23. The amplitude at the tip of the tuning fork 23 is measured by the Michelson interferometer 37. The graph indicating the scanning position is displayed at the horizontal axis of an oscilloscope and the graph indicating the quantity of the reflected light at the vertical axis. The optical scanner suitable for the high-speed and high- accuracy scanning over a wide range is obtd. in this way.

Title: Information processor
Inventor: NAKAJIMA YASUSHI
IPC: G06F13/28
Filed: 1990-10-04
Abstract: PURPOSE:To transfer the data to an output device from a main memory at a high speed by providing a FIFO to temporarily hold the data transferred in DMA from the main memory and performing the DMA transfer of data between the main memory and the FIFO and the transfer of data between the FIFO and the output device asynchronously with each other. CONSTITUTION:An input/output timing control part 7 gives a DMA request to a DMA controller 4 when a FIFO 6 provided between a main memory 3 and an output device is ready to receive the data. Thus the controller 4 transfers in DMA the data stored in the memory 3 to the FIFO 6. At the same time, the part 7 applies a strobe signal to the output device to fetch the output data on the FIFO 6 when the FIFO 6 is ready to output the data and also the output device is ready to receive the data. These two data transfer operations are carried out asynchronously with each other and at the same time. Thus the data can be transferred to the output device from the memory 3 at a high speed.
