Title: Analyzing method of total nitrogen in water quality
Inventor: OJIWA SHINICHI
IPC: G01N31/00
Filed: 1978-02-18
Abstract: PURPOSE: To analyze the total nitrogen contents in water quality accurately and yet continuously by converting the nitrogen compounds in water to nitrogen monoxide and quantitatively analyzing this nitrogen monoxide.  
     CONSTITUTION: Watre containing nitrogen compounds such as ammonia-, nitrate-  or nitrogens is steadily introduced into a carburettor 3 by a metering pump 2. On  the other hand, a gas containing oxygen, e.g., air, is fed at a constant flow rate into  the carburettor 3 via flowmetr 1. The carburettor is heated at the temperature sufficient for the water under measurement to perfectly vaporize, by which the water  under measurement is perfectly vaporized to a gas state and the gas is then admitted into an ammonia/nitrogen monoxide converter 4 filled with oxidation catalysts  having been heated at 700 to 800°C. The vaporized gas is then contacted with the  oxidation catalysts to convert the nitrogen compounds in the vaporized gas entirely  to nitrogen monoxide gas. Next, this nitrogen monoxide gas is admitted into a moisture remover 5 to get rid of the moisture in the gas, after which its nitrogen  monoxide concentration is measured with a nitrogen monixide analyzer 6 of chemiluminescence or infrared absorption type, whereby the total nitrogen components in  the water under measurement are detected as nitrogen monoxide quantity.

IPC: G06F7/50
Filed: 1985-02-01
Abstract: PURPOSE:To employ both addition and subtraction between a sign absolute value and a sign complementary number at a high speed stably in terms of circuitry by selecting the output of a carry look ahead circuit with the carry of the most significant digit of one of doubled carry look ahead circuits and then controlling an adder. CONSTITUTION:The adder is a carry look ahead type connected to the 1st and the 2nd carry look ahead circuits 31 and 32. A sign control circuit 10 outputs the signs of a couple of operands inputted to the adder independently of each other as the 1st and the 2nd sign outputs as they are, while the polarities are inverted, or while the positive or negative sign is replaced. A preliminary complementary circuit 20 makes either of the couple of operands inputted to the adder into a complementary number when the 1st and the 2nd sign outputs from the sign control circuit are different from each other. A post-end complementary circuit 25 makes the addition output of the adder into a complementary number when the 1st and the 2nd sign outputs from the sign control circuit are different from each other and there is no carry from the most significant digit of the 1st carry lock ahead circuit.

Title: Retrieving device of target track position

IPC: G11B21/08
Filed: 1983-02-10
Abstract: PURPOSE:To stop accurately a shift stage for optical system at a desired address of the track designated on a disk despite the large eccentricity of the disk, by controlling the counting of the clock signals obtained from the tracking error signals by means of the detecting signal. CONSTITUTION:The output of each stage of an up/down counter 30 is used to the address signal of a function generating circuit 32 consisting of a read-only memory and supplied to the circuit 32 via an address decoding circuit 31. The output of the circuit 32 undergoes D/A conversion through a D/A converting circuit 23 and turned into the voltage which controls the actual speed of the shift stage for optical system. The output of a relative phase detecting circuit 34 is supplied to a clock control circuit 35. Thus the control is carried out so that the clock pulse delivered from a waveform shaping circuit 33 is not supplied to the counter 30 for a period when the track on a disk moves back, i.e., while the output of the circuit 34 is kept at a high level. Thus the position shift errors can be decreased.
