Title: Refreshment controller for random access memory
Inventor: HITOMI AKIRA
IPC: G11C11/406
Filed: 1980-12-19
Abstract: PURPOSE:To shorten the overhead time of memory access, by outputting a refreshment signal repeatedly right before the start of the transfer operation of a DMA controller every time a memory-bus use acknowledge signal is outputted from an arithmetic controller. CONSTITUTION:When a DMA controller sends a bus request to an arithmetic controller, a bus-use acknowledge signal BUSACK is supplied to an FF104 to operate an FF105, whose output is supplied to a multiplier 103; and the output of a counter 102 is sent to a DRAM as a refreshment address signal MADR. Then, the output of an FF106 is converted through an AND gate 107 into a refreshment signal RASREF, which is outputted. The input of the multiplier 103 is switched to the side of a multiplier 101, and the inverted output of the FF105 is supplied to an AND gate 108, whose output is inputted to the counter to update a refreshment address, thereby outputting a refreshment signal repeatedly shortly before the start of DMA transfer in response to every signal BUSACK. Consequently, the overhead time of memory access is shortened.

Title: Inspection cell
Inventor: HAARARUTO DAANIGERU
IPC: G01N21/05
Filed: 1988-07-21
Abstract: PURPOSE: To prevent the fluctuation of the distance between windows for measurement caused by the ambient temperature by matching the efficient of thermal expansion of the material of window holders holding the windows to that of the material constituting a frame holding the holders in an inspection cell using an optical means. CONSTITUTION: A pair of windows 3 and 3 which lead light waves from one light wave transmitting body 13 to another light wave transmitting body 13 is provided in a measurement chamber 2 which passes a medium to be measured and the windows 3 and 3 are held by window holders 4 and 4. In an optical inspection cell having such a constitution, the coefficient of thermal expansion of the material of a frame 5 holding the holders 4 and 4 is matched to that of the material constituting the holders 4 and 4. When the coefficients of thermal expansion of the materials are matched to each other, the fluctuation of the measurement distance 18 between the windows 3 and 3 by the variation of the ambient temperature can be compensated with the length fluctuation of the frame 5.  Since the distance fluctuation between the windows 3 and 3 caused by a temperature change becomes smaller, the measurement error caused by the temperature change can be reduced.
