Title: For measuring sulfur content
Inventor: YAGAWA AKINORI
IPC: G01N31/00
Filed: 1993-07-29
Abstract: PURPOSE:To allow easy and convenient determination of the content of sulfur derived from sulfides in a sample by bringing a solid sample containing sulfides into contact with an acid to produce hydrogen sulfide and then measuring the concentration thereof. CONSTITUTION:An inner tube 4 is inserted through a solid sample throw-in port 3 into an outer tube 1 thus forming a closed space 5. The volume of the space 5, i.e., the inner volume, is determined based on the extent of insertion of the inner tube 4. When the inner volume is regulated to a predetermined volume A and a predetermined quantity of solid sample and an acid, e.g. hydrochloric acid, are contained therein and brought into contact each other, sulfides in the solid sample reacts on the hydrochloric acid to produce carbon dioxide gas and hydrogen sulfide gas. Consequently, the inner volume of the variable inner volume reaction vessel increases. After ending production of gas, the liquid component is discharged through a gas suction/discharge port 2 and the inner volume B is measured. A concentration measuring means is coupled to the port 2 and the quantity C of hydrogen sulfide in the vessel is determined. The content of sulfur derived from sulfides in the sample is then calculated based on the values A, B, C.

Abstract: PROBLEM TO BE SOLVED: To ensure enough bonding strength between a fiber reinforced plastic tubular body and a metal member and realize a low cost assembly by a method wherein the circumferential linear expansion coefficient of the inner peripheral surface of a fiber reinforced plastic tubular body is specified. SOLUTION: By making the circumferential linear expansion coefficient of the inner peripheral surface of a fiber reinforced plastic tubular body equal to 8×10<-6> / deg.C-15×10<-6> / deg.C or adjacent to be equal to or nearly equal to the linear expansion coefficient of a metal or of steel so as to eliminate or make extremely small the difference between the mounts of thermal expansion of both the tubular body and the metal member at the bonding between them, a high bonding strength is obtained. As the reinforcing fiber of the FRP tubular body, a carbon fiber is mainly used preferably so as to obtain a lightweight and highly rigid tubular body and two or more different reinforcing fibers may well be employed jointly.  When two or more different reinforcing fibers having different moduluses of elasticity are used in layers, which run obliquely by the tilting angle to an axial direction of ±75-90 deg., circumferential moduluses of rigidity are separately and respectively calculated and then added together.

Title: Magnet generator
Inventor: TAKAGI ATSUSHI
IPC: H02P9/48
Filed: 1991-07-04
Abstract: PURPOSE:To obtain a generator in which output voltage can be maintained constant regardless of variation of load through the use of a synchronous generator employing a permanent magnet as a field pole. CONSTITUTION:Output voltage of a synchronous magnet generator 1 is detected through a voltage detector 5. A comparator 6 outputs the difference between a detected output voltage and a reference voltage. When the output voltage is higher than the reference voltage, a controller 8A delivers a phase control amount corresponding to the difference to a phase controller 4. Consequently, a compensation current having phase lag corresponding to the difference flows through a reactor 3. The compensation current causes to increase lagging component of armature current and thereby armature reaction is enhanced thus lowering the output voltage.
