Title: Method for measuring amount of carbon
Inventor: SENOO YOSHIO
IPC: G01N7/18
Filed: 1991-07-19
Abstract: PURPOSE:To obtain a device for measuring an amount of carbon which improves a reaction efficiency between an organic body within a sample liquid and ozone which is an oxidizer and can measure an accurate amount of carbon. CONSTITUTION:Ozone gas which is generated by an ozone gas generation device 6 is introduced into a deaerator 4, thus enabling a sample liquid to be subjected to bubbling by the ozone gas. Therefore, an inorganic carbon such as carbon dioxide and ion bicarbonate which are dissolved into the sample liquid is deaerated and further ozone gas is dissolved into the sample liquid in saturation state. Then, ozone which is dissolved into the sample liquid by the deaerator 4 converts an organic body within the sample liquid to carbon dioxide efficiently within a reaction vessel 6.

Title: Output selecting system for triplicate system
Inventor: YAMADA TAKAO
IPC: G06F11/18
Filed: 1986-08-01
Abstract: PURPOSE:To simplify the constitution, to reduce the cost and to improve the reliability by sharing a triple system output selecting circuit and a dual system output selecting circuit circuit. CONSTITUTION:When the system is normally operated as a triplicate system, data from an output buffer 24 is eliminated by buffers 22A-22C in an output selecting part 22. Output data of controllers A-C are used as the input of a majority selecting circuit 23A of two out of three (2/3). If the controller in one system is faulty during operation of the triplicate system and the system is operated as the dual system, the output data of the faulty controller is eliminated in the output selecting part 22. The data of the output buffer 24 is used as one input of the majority selecting circuit 23A of 2/3 inserted of output data of the faulty controller. When coincidence between two input data out of three input data is detected by three AND gates AN1-AN3 and an OR gate OR in the majority selecting circuit 23A of 2/3, coinciding data is taken into the output buffer 24 and is outputted.

Title: Method of forming resist mask
Inventor: JIYOOJI AREKISANDAA UOOKAA
IPC: G03F1/00
Filed: 1983-09-30
Abstract: A method for forming a self-aligning resist mask (14) over a surface of an alumina ceramic substrate (10) having a molybdenum or other metal pattern (12) at said surface. First, the surface is blanket coated with a negative resist (14) sensitive to aluminum-emitted X-rays. A blanket dosing of the substrate with resist-insensitive X-rays induces X-ray emission by the aluminum penetrating said resist. The aluminum X-ray emission is screened by said molybdenum pattern at the surface and the resist adjacent the surface molybdenum pattern is penetrated by the aluminum X-ray emission. The resist is developed for removal thereof over the molybdenum pattern while retaining the resist doped by said aluminum X-ray emission. Further metallization can be accomplished by evaporation or sputtering to blanket coat the developed resist with a conductive metal followed by removal of the resist with the metal coating thereon such that the metal coating is retained on the molybdenum pattern.

Title: Repetitive signal detecting circuit
Inventor: HIRAGUCHI MASAYOSHI
IPC: H04L27/38
Filed: 1986-07-31
Abstract: PURPOSE:To preclude misdetection due to noise by deciding levels of the sent signals of a 1st and a 2nd filters. CONSTITUTION:A demodulated signal is sent to a low-pass filter 1, also sent to a subtracter 2 to subtract its DC component, and sent to a delay device 3 and a multiplier 4. The delay device 3 delays the signal by one cycle and the multiplier 4 multiplies the sent output of the subtracter 2 by the conjugate signal of the sent signal of the delay device 3 and sends the result to a low-pass filter 5. The LPF 5 extracts the DC component of the sent signal of the multiplier 4 and sends it to a decision circuit 6, which generates a pulse only when the signal exceeds a predetermined threshold value. An absolute value circuit 7, on the other hand, calculates and sends the absolute value of the sent signal of the LPF 1 to a decision circuit 8, which generates a pulse only when the absolute value exceeds a predetermined threshold value. A discriminating circuit 9 generates a pulse indicating the arrival of a repetitive signal according to whether or not a pulse arrives. Consequently, the threshold values for the level indentification of the discriminating circuits 6 and 8 are set properly to preclude misdetection due to the noise.

Abstract: PURPOSE:To economically remove phenols and(or) aromatic amines from the aq. soln. thereof with a small amt. of catalyst by reacting hydrogen peroxide kept at a specified concn. with the org. compds. above-mentioned in the presence of peroxidase as catalyst. CONSTITUTION:The peroxidase is dissolved in a phenol aq. soln. and hydrogen peroxide is added at intervals of fixed time period.
