Abstract:
A method of reclaiming a head suspension includes detaching a slider 225 from a tongue 221 of the head suspension and removing an adhesive 227 remaining on the tongue 221. Removing the adhesive 227 remaining on the tongue 221 includes feeding a solvent 243, which promotes the removal of the adhesive 227, to a part of the tongue 221 where the adhesive 227 remains and promoting the removal of the remaining adhesive 227 from the tongue 221 by applying physical energy to the adhesive remaining part on the tongue 221. The physical energy is produced by heating, supersonic vibration, and the like. The method easily removes the adhesive 227 from the tongue 221 without directly applying mechanical force to the tongue 221, thereby improving yields.

Abstract:
An actuator is provided with an output shaft connected to a driving gear, a pair of cam followers turned by the shaft and driving the cams held on driven shafts urging members held in housings of the driving gear, a rotation retaining plate mounted on the output shaft so that the rotation retaining plate cannot be rotated relatively to the output shaft, a plurality of pressing parts formed on the rotation retaining plate so as to project therefrom, and slits for preventing the driving gear and pressing parts from interfering with each other. The rotation of the driving gear is transmitted to the output shaft via the springs and rotation retaining plate. When the rotation of the driving gear is continued with the output shaft locked and stopped, one of both end portions of each spring is pressed by the corresponding pressing member.
Abstract:
An analytical method capable of easily, rapidly, and accurately determining concentrations of a multi-component aqueous solution. Near-infrared spectra of a standard solution containing k components of known concentrations are measured n times within a range of 1,500 to 1,850 nm. A loading matrix of p columns by m rows and an intermediate matrix of k columns by m rows for an appointed factor number m are obtained from a response matrix of p columns by n rows consisting of p absorbance values of the respective spectra in a calibration stage and p absorbance values of a near-infrared spectrum within a wavelength range of 1,500 to 1,850 nm of a test liquid. The test liquid contains k components including pure water of unknown concentrations. The concentrations of the k components are determined from a group of absorbance values and the loading and intermediate matrices obtained in the calibration stage by a matrix operation in an prediction stage. In the calibration stage, k+1 characteristic contents can be obtained by adding a solution temperature as one of characteristic items, and k concentration values and one temperature value can be obtained in the prediction stage.
Abstract:
A device according to the present invention includes an interferometer which produces interference fringes from light received from a light source. The interference fringes are imaged onto a photo-diode array which transforms the imaged interference fringes into a single set of electric signals. The single set of electric signals is digitized and stored as a group of consecutive data points which represent an interferogram signal containing a DC component. The data points are processed to obtain moving average values representing the DC component of the interferogram signal. The moving average values are subtracted from the data points to obtain a clean interferogram signal which is Fourier-transformed to obtain a spectrogram of the light source.
