摘要:
A wye-branching optical circuit including an input waveguide and at least two output waveguides, which are single mode waveguides or multi-mode waveguides in which only several modes are propagated. The waveguides are formed in a substrate, wherein a portion of the input waveguide is a low effective refractive index waveguide where higher order modes are cut-off, and the effective refractive index of a fundamental mode is lower than in the other waveguides formed in the substrate.

A thick resin film is formed on the joint part of a welded metallic can body by first coating the joint part with a primer composed of a solution of a thermosetting resin in an organic solvent and drying it, and then coating the dried primer layer with a slurry paint composed of a dispersion of a thermoplastic resin powder in a poor solvent, and drying the coating. The resin powder has a specific gravity differing from that of the poor solvent by not more than 0.2.

A pair of magnets for producing a mirror magnetic field are disposed outside of an electrode structure carrying a target. Microwaves from a microwave source are introduced toward and into a space defined by the mirror magnetic field for generating high-density plasma. While maintaining this high-density plasma over a wide area of the surface of the target, an electric field substantially perpendicular to the surface of the target is applied for sputtering of the target material. The optimized conditions for plasma generation can be selected when the high-density plasma formed outside of a processing chamber is guided to migrate toward an area above the target in the processing chamber. Capability of sputtering of the material from the entire surface of the target increases the rate of film deposition on a substrate and improves the target utilization rate (the quantity of the material deposited on the substrate/the usable area of the target).

A coating apparatus is disclosed. The apparatus comprises a coating head having a slide face along which a coating liquid flows down and a roll moving a continuous web downwardly. The slide face and the roll define a space for forming a sustained liquid mass therein. The coating head has a bottom face which is provided with a groove in the proximity of and substantially parallelly to the slide face whereby a thin liquid film is formed on the web at high speed.

A signal modulator that can control transmission power if level adjustment of a continuous signal from an oscillator is executed is provided. A pulse generator of one example of a signal modulator includes an oscillator, a control signal generator, a multiplier, a filter, and a control section. The oscillator and the multiplier are active circuits formed of active elements. A continuous signal is output from the oscillator and is input to the multiplier and the multiplier intermittently operates by a control signal output from the control signal generator, whereby a pulse signal is generated and the power level is easily adjusted by a signal from the control section.
