Title: Method for measuring immune reaction by intensity fluctuation of light
Inventor: NANBA AKIHIRO
IPC: G01N21/51
Filed: 1985-01-28
Abstract: PURPOSE:To improve measurement accuracy by removing the frequency component higher than the relaxation frequency of powder spectral density in the stage of measuring immune reaction by making use of the intensity fluctuation of scattered light by fine particles. CONSTITUTION:The immune reaction based on an antigen-antibody reaction is measured by making use of the intensity fluctuation of the scattered light by fine particles. A laser beam 2 from a light source 1 is made into a beam 4 by a semi-transparent mirror 3 in this stage. Said beam is condensed by condenser lens 6 and is projected to a cell 7 in which the antigen-antibody reactive liquid contg. the fine particles 9 is contained. The scattered light thereof is made incident through a collimator 10 on a photodetector 11 and the output thereof is supplied via a low-pass filter 16 which removes the frequency component substantially higher than the relaxation frequency of the detected power spectral density to a data processing unit 14. The measurement with high accuracy is thus made possible without being affected by noise, etc. even if the particle concn. and the quantity of the measuring light are low.

Title: Control system for time division type high frequency inverter
Inventor: SHIBUYA TADASHI
IPC: H02M7/48
Filed: 1981-02-03
Abstract: PURPOSE:To prevent a thyristor from being damaged by supplying a gate current in advance when the thyristor is refired due to the increase of a load voltage. CONSTITUTION:The firing pulses of the thyristors S11-S14, S21-S24 of respective thyristor circuits ST1, ST2 use the gate current of double pulses. For example, double pulses P12 to be applied to thyristors S11, S14 are employed, the first pulse is applied at the time t1 to turn ON the thyristors S11, S14, then flowing a load current of half cycle, and then the second pulse is applied to the thyristors S21, S24 at the time t2 at the same timing as the first pulse of the thyristors S21, S24. The load voltage is raised to the value capable of refiring the thyristors S11, S14, by the second pulse, but since it becomes the refiring state (at the time t2') in the state that the gate current is applied to the thyristors, it can prevent the damage of the thyristors in this manner.
