Patent EP-0249980-A2 (EP)
Inventor: WATABE KENZO
IPC: G01R27/02
Filed: 1987-06-19
Abstract: Disclosed is a method and apparatus for detecting conductive material contained in glass fiber (5), in which it is possible to detect fine conductive material contained in glass fiber (5) under the condition that the glass fiber (5) is running in the process of manufacturing the glass fiber (5), and in which it is possible to detect only the conductive material accurately without being affected by moisture or the like. The method and appa­ratus are arranged such that a state of oscillation is generated in advance by using an LC oscillator (2) or the like disposed in the vicinity of a moving path of glass fiber (5) in the manufacturing process so that a change may be caused in a reactance element (l) in the oscillator (2) by conductive material which may be contained in the glass fiber (5) to thereby cause a change in the state of oscillation, the change in oscillation output being taken out as changed in amplitude and frequency by using an AM detector (6) and an FM detector (7) respectively, the taken-out AM and FM detection signals (S₁, S₂) being combined with each other by a composite wave generator (8), the composite wave signal (S₃, S₄) being compared with a reference level (V₀) to thereby detect the con­ductive material maldistributed in the glass fiber (5).

Abstract: A diaphragm condenser for measuring very small pneumatic alternating pressures, as occur in particular in gas analysers with optopneumatic detectors, has a ceramic base plate (1). The ceramic base plate (1) carries an annular stem (2) over which a metal diaphragm (4) is stretched. Arranged inside the annular stem (2) is a fixed electrode (3) which together with the metal diaphragm (4) forms a condenser whose capacitance is a function of the deflection of the metal diaphragm (4). The annular stem (2) is formed by application of material to the ceramic base plate (1), and its height determines the distance between the fixed electrode (3) and the undeflected metal diaphragm (4). The fixed electrode (3) is formed by application of a metal coating to the ceramic base plate (1). The metal diaphragm (4) is held between two rings (5, 6) of a tension-ring arrangement which is connected to the ceramic base plate (1) via at least three screws (7, 8, 9). The tension in the metal diaphragm (4) can be set via the screws (7, 8, 9). A disc spring (10) is arranged between the tension- ring arrangement and the ceramic base plate (1). The screws (7, 8, 9) are passed through through-holes in the disc spring (10). The disc spring (10) absorbs the forces arising due to the weight of the rings (5, 6). <IMAGE>

Abstract: Disclosed is a control apparatus (14) for a multi-joint manipulator (10) constituting a multijoint robot arm having links (12a, 12b) mechanically and rotatably coupled to each other at joint portions. Actuators (22a, 22b) for rotating the links and angle sensors (24a, 24b), for measuring the amount of link rotation, are provided at the joint portions. The control apparatus (14) includes a driver (30) for the actuators (22a, 22b), a detector (32) for detecting the actually measured data of the links (12a, 12b), in response to the output signals from the sensors (24a, 24b), and a parameter identifier unit (36) which is made operative when it is designated. The parameter identifier unit (36) is automatically connected to the driver unit (30) and the detector (32) via a switch unit (34), only when an initial dynamical model of the manipulator (10) exceeds a predetermined allowance, thereby identifying the dynamical model of the manipulator (10). The identification result is supplied to a parameter computation unit (40), which calculates new manipulator control parameters in accordance with the identification result. The new control parameters are calculated to compensate for a change in the manipulator dynamical model. The new control parameters are transferred to a software servo unit (38), and replace standard control parameters stored therein.

Abstract: A chemiluminescence method for assaying compounds containing primary amino groups using 1-cyano-2-substituted benz[f]- or naphth[f]-isoindole fluorescers is disclosed. The 1-cyano-2-substituted benz[f]- or naphth[f]-isoindole (CBI or CNI) is formed by reacting a compound containing a primary amino group with naphthalene-2-3-dicarboxaldehyde or anthracene-2,3-­dicarboxaldehyde in the presence of cyanide ion. The reaction product of hydrogen peroxide with an oxalate ester is then combined with the CBI or CNI to form an analyte which exhibits chemiluminescence. A detector is used to measure the chemilumi­nescence emission from the chemiluminescence derivatized analytes. Compounds containing primary amino groups which may be assayed according to the present invention include primary amines, amino acids, peptides and catechloamines. The method can also be adapted to the analysis of trace amounts of cyanide ion and hydrogen peroxide.
