摘要:
An ultrasonic manipulation apparatus has a plurality of ultrasonic wave oscillators arranged in two dimensions to trap, fix or move particles to an optional position in the solution or perform cell fusion by using a gradient force obtained by superposing one over another the gradient force fields generated by ultrasonic waves produced by a plurality of ultrasonic wave oscillators. The ultrasonic wave oscillators, functioning independently of one another, can emit ultrasonic waves with optional intensities and phases, and by using an external force produced by superposed gradient force fields generated by ultrasonic waves, particles are handled easily.

A chamber for exerting an ultrasound beam on a sample solution containing particles to be concentrated, separated or arranged is provided with a view toward arbitrarily controlling the shape of a spatial distribution of potential energy created by the ultrasound beam and concentrating, separating or periodically arranging the particles. In contrast to the chamber, irradiation ultrasound sources for generating ultrasound beams are provided to create an ultrasonic intensity distribution for producing a position potential energy distribution used to exert a force forwarded in a predetermined direction or a force staying at a predetermined region to each particle. Thus, a specific spatial distribution of potential energy can be realized by ultrasound beams each having a specific intensity, a specific frequency and a specific phase or an ultrasound beam formed by superimposing these on one another. Further, at least one suction hole for recovering separated solvents or particles is defined in a wall surface of the tube, which is orthogonal to the flow of the sample solution.

A process for producing a protein-oriented membrane which is enhanced physically and chemically by orienting protein and cross linking the oriented protein together, is described. The proteinaceous membrane which is subjected to orientation treatment alone is weak physically and chemically, and its processing and handling are therefore difficult. However, according to the present invention, the protein after the process of orientation is cross linked together to produce a protein-oriented membrane remarkably enhanced physically and chemically.

A metal vapor discharge lamp and a lighting fixture are downsized without causing breakage of an outer tube because of optimization of a positional relation among the outer tube (34), an inner tube (32), and an arc tube (40). The metal vapor discharge lamp has the arc tube, the inner tube housing the arc tube, and the outer tube housing the inner tube. The positional relation satisfies the relation of 2×A+B≧1.06. In a cross section of the lamp (the cross section of the arc tube is unshown for convenience), A (mm) represents the shortest distance between the arc tube and the inner tube along a line in a radial direction of the inner tube, and B (mm) represents a distance between the inner tube and the outer tube on a line segment C that is extension of the line.

According to one embodiment, a method for manufacturing a thin film magnetic head includes forming on a substrate magnetic head portions having a magnetoresistive element and resistance detection elements for measuring an amount of polishing; slicing the substrate to form at least one row bar; polishing the ABS of each row bar; forming rails on the polished ABS; and cutting each row bar to separate each magnetic head portion. The step of polishing the ABS includes measuring a resistance of each resistance detection element and a resistance of each magnetoresistive element; calculating an offset value between the resistance detection element and the magnetoresistive element; and calculating a final resistance of the resistance detection element by using the calculated offset value. When the resistance of the resistance detection element reaches the final resistance, polishing of the ABS of the row bar is terminated. Other methods are presented as well.

To improve the laser annealing process for polycrystallizing amorphous silicon to form silicon thin films having large crystal particle diameters at a high throughput, the present invention is directed to a process of crystallization by irradiation of a semiconductor thin film formed on a substrate with pulsed laser light. The process comprises having a means to shape laser light into a linear beam and a means to periodically and spatially modulate the intensity of pulsed laser in the direction of the long axis of the linear beam by passing through a phase-shifting stripy pattern perpendicular to the long axis, and collectively forming for each shot a polycrystalline film composed of crystals which have grown in a certain direction over the entire region irradiated with the linear beam.

摘要:
A laser light is projected to a thin film deposited on a transparent substrate, and measurement is performed on the entire measurement area of the substrate, and transmission intensity is measured by a transmission light intensity monitor and reflection light intensity is measured by a reflection light intensity monitor at the same points and at the same number of points on the substrate. From the value of “A=1−(R+T)” where R represents reflectivity and T is transmissivity, film thickness is measured and evaluated from the relation of the value A with film thickness. By this procedure, film thickness can be determined on 10,000 substrates or more per minute and film thickness of thin film can be measured over the entire substrate surface.
