Title: Bipolar ram
Inventor: AKIMOTO KAZUYASU
IPC: G11C11/414
Filed: 1983-06-10
Abstract: PURPOSE:To attain switching between an alternative current and a 1/2 current approximately equal to said alternative current which are supplied to a pair of output transistors with a simple circuit, by adding a function to an input data buffer to deliver a fixed intermediate level through a read-out operation. CONSTITUTION:In a writing mode of a terminal WE at a low level, a constant current I is flowed alternatively only to the side of an output transistor (TR) that produces output voltage V1 or V2 of a low level in an ON/OFF mode of a differential TR Q31 or Q30. A data input buffer DIB turns on a TRQ11 with a high level of the terminal WE to supply a constant current to resistances R4 and R5 by 1/2 respectively and fixes the output level at an intermediate level regardless of the signal supplied from an external terminal Din. The current I flows to the TRs Q30 and Q31 by 1/2 owing to the intermediate level of the output of the buffer DIB. Thus the reference voltage Vref can be obtained.

Title: Fluorescent x-ray analysis
Inventor: OCHI HIROTOMO
IPC: G01N23/223
Filed: 1985-05-15
Abstract: PURPOSE:To suppress the occurrence of bubbles in the midst of X-ray irradiation and to attain the fluorescent X-ray analysis of a liquid specimen by carrying out the X-ray irradiation under conditions where the liquid specimen is subjected to convection. CONSTITUTION:The liquid specimen 14 is previously heated within a desired temperature range, and put into a liquid specimen container. The surface to be analyzed of the specimen 14 is merely covered by a thin Mylar film or beryllium thin plate 6. Accordingly even if the partial irradiation with the X-ray 9 causes heating, the surface to be analyzed can be cooled by an external temperature. As a result the temperature difference between upper and lower parts permits the upper cool specimen to flow downward and the lower specimen to rise, thereby causing the convection. Due to the convection arising in the specimen 14, the partial heating is relaxed to prevent the occurrence of bubbles, whereby the fluorescence analysis can be possible without a drop in X-ray intensity.
