Title: Memory interleave control system
Inventor: SAKAGUCHI KAZUAKI
IPC: G06F12/06
Filed: 1988-05-31
Abstract: PURPOSE:To realize a high-speed access to a memory by securing the reading and writing actions in an interleave system between plural memory circuits and a memory bus. CONSTITUTION:A 0-th memory circuit (0) delays an access signal 1' received from a memory control circuit 21 by an extent equal to several clocks to change the signal 1' into an access signal 2'. This signal 2' is sent to a 1st memory circuit (1). Hereafter the signals 2' delayed by the fixed time are sent in sequence to plural memory circuits in the same way. Then the control is performed via a memory control circuit 21 so that the reading and writing actions are carried out via a memory bus 1 synchronously with the signal 1' (2'). Thus it is possible to realize a memory access applying an interleave system that works for each delay time of the access signal of the memory circuits (0), (1), (2),... respectively just by preparing a single access signal line led from the circuit 21. As a result, a high-speed memory access is possible.

Title: Inspecting device for surface fault
Inventor: KAMEI MITSUHITO
IPC: G01N21/892
Filed: 1981-08-26
Abstract: PURPOSE:To inspect a surface fault without moving parts to be inspected, by making a scanning pattern that scanning light draws similar to the outward  shape of the part to be inspected, and performing three-dimensional scanning  while varying the size with time. CONSTITUTION:Driving mirrors 6a and 6b are arranged while having driving axes set at right angles to each other, and are driven around their axes respectively. Incident light is scanned circularly by the driving mirrors 6a and 6b and reflected by a cylindrical internal surface reflecting mirror 5 to scan on a body 1 to be inspected in a circumferential direction. The driving mirrors 6a and 6b are driven by multiplying the input waveform by a factor K through AGC circuits 7a and 7b and then inputting the results to driving circuits 8a and 8b. When the coefficient K is varied as shown in the graph by a gain control signal generator 9, maximum angles of oscillation of the driving mirrors 6a and 6b  vary and the diameter of the circularly scanned pattern varies similarly. As a  result, while the body 1 to be inspected is fixed, the circumferential scanning  light 4 is moved in an axial direction for three-dimensional scanning.
