Patent JP-H0210763-A (JP)
Title: Semiconductor integrated circuit
Inventor: DENDA AKIRA
IPC: G11C11/407
Filed: 1988-06-28
Abstract: PURPOSE:To seek to reduce the number of elements by controlling the input threshold voltage from the outside. CONSTITUTION:If a control signal is defined as L, a P-channel MOS transistor (PMOS Tr) 9 is turned ON, and an N-channel MOS transistor (NMOS Tr) is turned off. The potential at joint A rises up to VDD, and the PMOS Tr 11 and the NMOS Tr 12 become ordinary inverter connection. When a control signal becomes H, a Tr 9 is turned off, and a Tr 10 is turned on, which let currents flow to a diode group, and the joint A becomes VDD-VF, and VGS as of the Tr 11 lowers and ¦VT¦ increases by the substrate effect of VF and an ON resistance increases and input threshold voltage lowers than that when the control signal is L. By doing it this way, there is no necessity of constituting an input circuit for every input threshold voltage, and the number of elements can be reduced.

Abstract: PURPOSE:To provide a novel method for generating nuclear energy as a difference between an amplified energy and a thrown-in energy. CONSTITUTION:A multi-stage energy generating method comprises a step for providing a magnetic body 1 with primary and secondary conductor coils 2, 3, a step for providing two gap forming terminals 4, 5 having gap regulating mechanism at the opposite ends of the primary coil, a step for providing a pulsating 7 DC power supply 8 having variable primary potential 6, and a step for feeding the primary coil 2 with a current having potential overcoming the voltage drop across a resistor having resistance increasing as the gap widens. Electromagnetic energy generated in the primary coil is taken out from a secondary coil 3 in a first stage I and the energy generated in the first stage I is fed as power supply for a second stage II in the inventive multi-stage energy generating method. When the primary coils in two electric circuits A, B are fed with pulsating power, one circuit is interrupted during conduction of the other circuit and powers generated in two secondary coils are combined and continuous DC electric, i.e. energy, is taken out in the form of magnetic force from the magnetic body 1 at some stage.

Title: Atomic absorption analysis method
Inventor: DAIDOJI HIDEHIRO
IPC: G01N21/27
Filed: 1987-07-01
Abstract: PURPOSE:To enable the qualitative or quantitative detection of a desired substance, by utilizing a plurality of spectral lines generated by the substance to be detected. CONSTITUTION:First the detection of copper is conducted sequentially by means of a spectral line of 324.7nm. When the concentration of a sample is found within a range from 10<-2> to 10ppm, an output is generated on the basis of a calibration curve I. When this output is not detected, the detection based on a calibration curve II is conducted by using a spectral line of 327.4nm. Then an output is generated when the concentration of the sample is 10<-1>-10<+2>ppm. When the output is not yet obtained, the spectral line is switched further over to 249.2nm and the detection is conducted on the basis of a calibration curve III. When the concentration is 10<3>ppm or below on the occasion, the existence of copper is detected and the output is generated. Accordingly, a qualitative analysis can be implemented by conducting the above-stated operation automatically. In the case of a quantitative analysis, the concentration of a standard solution to be measured is indicated. Thereby an appropriate working curve is called out in the same way as in the qualitative analysis, and the concentration thereof can be known from an absorbance A.
