A device and method for testing a fiber-composite component, which is to be processed by means of bonding, for the presence of at least one substance out of a selection of possible contaminants. A surface heating device for regional heating of a part-zone of the fiber-composite component to be bonded is performed for desorption of contaminants. A sensor array with a plurality of sensors detects contaminants in the gas phase, and a control device ascertains and signals contaminations which are found. An extractor device can be employed to extract machining dust from the fiber-composite component to a desorption device.

A coated nickel hydroxide powder that has a cobalt compound coating having improved uniformity and adhesion properties on the surface of particles thereof and is therefore suitable for a positive electrode active material of an alkaline secondary battery is obtained by coating the surface of nickel hydroxide particles with a cobalt compound, and has a transmittance ratio of 30% or higher as determined by (A−B.sub.max)/(B.sub.0−B.sub.max). The transmittance A (coated nickel hydroxide powder), the transmittance B.sub.0 (nickel hydroxide powder), or the transmittance B.sub.max (nickel hydroxide powder and cobalt compound containing cobalt in an amount corresponding to the amount of cobalt contained in the coating) can be determined by measuring the transmittance of a tubular transparent cell after shaking the tightly-closed transparent cell containing each powder for a certain time and then taking the contents out of the transparent cell.

First and second operations are executed under control of a peeling inspection control apparatus functioning as a peeling and grasping control unit. In the first operation, a processed surface contact state in which a processed outer peripheral surface of a contact roller and a surface of a lead wire are in contact with each other is maintained, and contact roller rotation operation is executed in which the contact roller is moved on the surface of the lead wire while the contact roller is being rotated. During execution of the first operation, a tip portion of the lead wire is peeled from a glass substrate. Thereafter, in the second operation, grasping operation is executed in which the tip portion of the lead wire peeled from the glass substrate is grasped by a grasping mechanism.

An apparatus and method for separating welded multi-layered samples has a slotted engine-driven spindle that twists and pulls a layer from the sample, breaking the welds as the layer winds around the spindle. The sample is held between two clamps and a tensioning cylinder pulls a movable first clamp against the second stationery clamp. Sensors may sense the force required to break the welds and the data may be stored and analyzed in a computer.

The present invention relates to a prediction model for a lip sticking force of a cigarette tipping paper, a construction method and a prediction method thereof, which belongs to the technical field of analysis and detection. In the method, the stepwise regression analysis is performed on the lip sticking force and values of the dynamic friction coefficient and the grammage of the cigarette tipping paper to obtain a model for predicting the lip sticking force of the cigarette tipping paper. When checking the accuracy of the model, it is found that the predicted value and the measured value basically fall near the 1:1 line, R.sup.2 index is 0.99, and the normalized root mean square error (nRMSE) is 2.64%. The present invention provides a method capable of quickly and simply quantifying a sticking force of the cigarette tipper paper to lips
