IPC: G01N30/90
Filed: 1982-04-14
Abstract: A chromatographic plate for use in thin-layer chromatography for the detection of drugs in a physiological medium comprises an inert substrate and an adsorbent material impregnated with a heavy metal oxidising agent, preferably a vanadium salt, which chemically reacts with a broad range of drugs, preferably basic amine-containing drugs, in the presence of a strong acid reagent, preferably concentrated sulphuric acid, to produce a characteristic colour on the chromatographic plate.

Abstract: PURPOSE:To automatically adjust the delivery speed of a mandrel to the optimum by changing over the operation/stop of a motor for an uncoiler and changing over the rotating speed of the motor to several stages when a coil material reaches an upper or a lower limit position. CONSTITUTION:The upper or the lower limit position of a loop in the coil material is detected by a detecting device 11 as a detecting means.

N increases the pitting corrosion resistance remarkably, yet above the upper limit of N deteriorates the hot workability, etc. Si dissolves in the matrix to strengthen it and improves the corrosion resistance, etc. The lower limit of Si is decided from the viewpoint of hot workability, etc., and the upper limit from the viewpoint of a reduction in the N dissolving limit and the structural balance. The upper limit of Cr is decided from the viewpoint of the structural balance, and that of Ni from the viewpoint of hot workability and a reduction in the N dissolving limit. Mn raises the N dissolving limit according to the Si, Cr and Ni contents, yet above the upper limit of Mn deteriorates the hot workability. Nb makes the grains fine and enhances the strength and hot workability, yet above the upper limit of Nb deteriorates the workability.

IPC: G11C19/28
Filed: 1984-03-31
Abstract: PURPOSE:To prevent a racing phenomenon and also to simplify the peripheral circuits by controlling a clocked selector and a clocked inverter with clock signals having phases reverse to each other. CONSTITUTION:A clocked selector 14 consists of the 1st AND gate 15, the 2nd AND gate 17 and a clocked NOR gate 18 which receives supply of the outputs of both gates 15 and 17 is synchronized with a clock signal phi1'. The output of the gate 18 is supplied to an input terminal of a clocked inverter 19 which is synchronized with the signal phi1. Then an output signal OUT is obtained from an output terminal of the inverter 19. Thus data are selected by a logical circuit not by the clock signal, and no delay is caused between both clock signals owing to latch signals phi1 and phi1'. This prevents a racing phenomenon. Furthermore the number of clocked drivers and clock signal wirings can be decreased since just clock signals phi1 and phi1' are needed to attain a suited application to conversion into a CMOS circuit.
